How to choose aeration equipment? Comparison of mass transfer effects of micropore aeration, traditional jet and GW jet aeration When selecting aerobic processes for sewage treatment, common solutions include microporous aeration, MTS jet aeration, traditional jet aeration and GW jet aeration. Many people will ask: Which type of aeration equipment has higher oxygen mass transfer efficiency? Can high-salt wastewater be used? Will maintenance costs get out of control in the future? This article uses unified comparison dimensions to help engineers quickly complete the selection of aeration equipment. 1. First, the conclusion: what aeration selection really compares Under the same water quality, gas source, air pressure, temperature and other conditions, the mass transfer coefficient of oxygen molecules per unit time is constant. Therefore, what really widens the gap is not "whether it can be oxygenated", but whether the following factors can be done correctly at the same time: 1. Bubble size (specific surface area) - the smaller the bubble, the larger the gas-liquid contact area is usually 2. Gas-liquid contact time - the longer oxygen stays and diffuses in water, the more complete the mass transfer will be. 3. Mixing intensity - the stronger the turbulence, the faster the interface is updated and the more uniform the dissolved oxygen distribution is. 4. Frequency and difficulty of maintenance - whether it is prone to scaling and clogging, and whether it can be maintained without stopping water. Combined with the actual performance of the equipment material and structure in sewage, you can determine which type of aerator is more suitable for your working conditions. 2. Comparison table of mass transfer effects of four types of aeration equipment Comparison item Microporous aeration MTS jet aeration Traditional jet aeration GW jet aeration Bubble size Small Large Large Small Gas-liquid contact time Changes with water depth Changes with water depth From the suction port to the bottom of the pool + the bubbles rise The longest (including pipeline transportation and secondary injection diffusion) Mixing intensity General (rising by gas) Strong (water vapor jet) Limited (no nozzle at outlet) Strong (secondary jet from the enhanced nozzle at the bottom of the pool) High salt wastewater adaptability Not suitable, prone to scaling and clogging Not suitable, prone to scaling and clogging Not suitable, prone to scaling and clogging Suitable, no obvious water-vapor interface, large diameter and not easy to block Mass transfer efficiency High at the beginning, then decays with use Not high Not high High and more stable Maintenance features High maintenance costs After blockage, water needs to be drained for repair. Easy to scale and clog Correct installation requires no maintenance under water, mainly maintaining the water pump outside the pool. 3. Microporous aeration: high initial efficiency, long-term attenuation and maintenance costs must be calculated The advantages of microporous aeration are small bubbles and high initial mass transfer efficiency. The gas-liquid contact time will change with the water depth; stirring mainly relies on the rise of gas, and the stirring force is average. It should be noted that microporous aeration has a water and air interface, so it is not suitable for wastewater with high salinity and is prone to scaling and clogging. The mass transfer efficiency will decrease with the increase of use time, and the maintenance cost will be high. If the project places more emphasis on long-term stable operation and low maintenance, this must be included in the full life cycle cost assessment. 4. MTS jet aeration: strong stirring power, but obvious shortcomings in mass transfer and maintenance MTS jet aeration has larger bubbles, and the gas-liquid contact time changes with the water depth; stirring relies on water vapor injection, and the stirring force is strong. Also due to the existence of water and air interface, it is not suitable for wastewater with high salinity and is prone to scaling and clogging. The overall mass transfer efficiency is not high. Once clogged, water can usually only be drained for repair. The impact of shutdown and maintenance difficulty are greater. It is more suitable for scenarios where the inspection window is not strict and the risk of water scaling is low. 5. Traditional jet aeration: simple structure, but large bubbles and limited stirring Traditional jet aeration has large bubbles; the gas-liquid contact time is from the suction port to the bottom of the pool, plus the time for the bubbles to rise to the liquid surface. There is no nozzle at the outlet of the equipment, and the stirring intensity is limited. There is also a water and gas interface, which is not suitable for wastewater with high salinity. It is easy to scale and block, and the mass transfer efficiency is not high. If the project requires higher oxygen utilization and stronger mixing in the pool, it is often necessary to upgrade to a high-efficiency jet solution with enhanced nozzles. 6. GW jet aeration: the longest contact time, more friendly to high-salt working conditions and low maintenance GW jet aeration bubbles are small. The gas-liquid contact time starts from the suction port and includes the transportation time in the horizontal and vertical pipes, as well as the time for the bubbles to spread and rise in the water after being sprayed through the booster nozzle - among all types of aeration devices, the gas-liquid contact time is the longest. The synergistic nozzle performs secondary jet injection at the bottom of the pool with strong stirring power. There is no obvious water and gas interface in the equipment, so it can be suitable for wastewater with high salinity; the nozzle has a large diameter, is not easy to scale and block, and has high mass transfer efficiency. Under correct installation conditions, the underwater part usually does not require maintenance and repair, and only routine maintenance or repairs are required on the water pump outside the pool. For sewage plants with standard upgrades, high-salt industrial wastewater, and sewage plants that want to reduce venting and maintenance, GW jet aeration is often a more reliable selection direction. 7. Selection suggestions: match according to working conditions, rather than just looking at nominal efficiency 1. If more emphasis is placed on initial fine bubbles and short-term oxygen utilization, microporous aeration can be evaluated, but a maintenance budget should be reserved for scaling and clogging and efficiency attenuation. 2. If strong jet agitation is required in the pool, but the risk of water scaling is high or it is difficult to drain the water for maintenance, MTS or traditional jets should be chosen carefully. 3. If you also pay attention to bubble fineness, longest gas-liquid contact time, secondary jet mixing, high salt adaptability and low underwater maintenance, give priority to comparing GW jet aeration. The core goal of aeration equipment selection is always to achieve a stable, maintainable, and full-cycle cost-controllable oxygenation solution under the target dissolved oxygen and mixing effects. 8. FAQ What are the main factors that affect the mass transfer effect of aeration equipment? Under the same water quality, gas source, air pressure, temperature and other conditions, the mass transfer coefficient of oxygen molecules per unit time is constant. The main factors that affect the mass transfer effect are bubble size (specific surface area), gas-liquid contact time and mixing and stirring intensity; the engineering selection should also simultaneously evaluate the frequency and difficulty of maintenance. Which aeration method is more suitable for high-salt wastewater? Micropore aeration, MTS jet aeration and traditional jet aeration all have water and air interfaces, which are more prone to scaling and clogging under high-salt conditions. GW jet aeration has no obvious water-vapor interface and a large nozzle diameter, making it more suitable for wastewater with higher salinity. Why is it said that GW jet aeration has the longest gas-liquid contact time? Because its contact process starts from the suction port, covers pipeline transportation, and then reaches the diffusion and rise of bubbles after the secondary injection of the booster nozzle at the bottom of the pool, the path is more complete, so the gas-liquid contact time is usually longer than other aeration devices.

Application of Jet Aeration in Sugarcane Wastewater Treatment I. Basic Project Overview Sucrose wastewater primarily originates from wastewater generated during ethanol production, Poor biodegradability, high viscosity, Poor humus formation, COD concentrations as high as 100,000–120,000 mg/L, Fully treated using biological methods, Complex manufacturing processes, high costs, and significant investment requirements. Based on the characteristics of this wastewater, Employing biological fertilizer technology, Utilizing facultative anaerobic bacteria to ferment and oxidize alcohol waste distillate into mature humic acid. Due to the high viscosity of the alcohol wastewater produced from sucrose, Microporous aeration discs or tubes are prone to clogging and produce uneven aeration, Low oxygen utilization rate, insufficient oxygen supply capacity, Traditional MTS jet aeration systems exhibit low oxygen utilization efficiency, Pipeline layout is complex, investment is high, and energy consumption is high. To address the above issues, Yunnan Yingmao Sugar Industry Co., Ltd. procured GW jet aerators from Chengdu Greenwater Technology Co., Ltd. for oxygen supply and aeration in the anoxic tank. III. Operational Processing Results In the anoxic tanks with dimensions of 18×18×3m, 25×15×4.5m, 20×20×3m, 14×14×3m, and 15×15×4.5m respectively, 2 sets, 3 sets, 2 sets, 2 sets, and 2 sets of GW1200 jet aerators were installed.

What are the components of an ozone jet dosing system? The PID flow of the jet ozone dosing system designed by Chengdu Lushui Technology Co., Ltd. is as follows: In the diagram, the markings are: 1-Oxygen source system, 2-Power water pump, 3-Venturi jet injector (primary jet), 4-Enhancing nozzle (secondary jet). A. Oxygen Source System: This mainly includes a liquid oxygen storage tank, vaporizer, oxygen pressure regulating and delivery pipelines or an oxygen generator, and oxygen pressure regulating and delivery pipelines. The oxygen source system supplies the raw gas for ozone production to the ozone generator. Under certain circumstances, it can also supply oxygen to the aeration tank simultaneously or separately, increasing the total oxygenation capacity of the aeration tank. B. Jet Aerator The jet aerator, powered by a pump, consists of a primary Venturi jet aerator outside the pool, secondary booster nozzles and piping installed inside the pool, and switching valves. 1. The pump provides the necessary energy for the Venturi jet aerator to draw in ozone, for the transport of the water-air mixture, and for the secondary spraying and mass transfer by the booster nozzles. 2. The Venturi jet aerator is the core component of the entire aeration system; the ozone mass transfer aeration process begins here. Ozone is drawn in by the high-speed water flow at the throat, forming a water-air mixture with uniform microbubbles within the primary Venturi jet aerator, thus initiating the mass transfer process. The water-air mixture is then transported through pressurized piping to the secondary booster nozzles, where ozone continues to transfer mass within the pool. 3. The enhancement nozzle is also a key component of the aeration system. Its function is to allow the supersaturated oxygen-laden water-air mixture to be sprayed a second time at the bottom of the tank, thoroughly mixing with the relatively low ozone content of the wastewater, thus facilitating mass transfer and improving ozone transfer efficiency and aeration uniformity. 4. The valve system's operation allows the ozone supply to be adjusted according to changes in water quality during the aeration process, while ensuring that water does not enter the ozone pipeline, guaranteeing the safety and cost-effectiveness of the system operation. C. Piping System 1. The piping system for the entire high-difficulty wastewater treatment system, combining biological treatment with advanced O3 oxidation for zero-discharge effluent, is simple, easy to manufacture and maintain. 2. For new projects, the power pump and Venturi jet aerator are located outside the tank. The jet aerator outlet is connected to the secondary enhancement nozzles via a pipe. The connecting pipe passes through pre-embedded holes in the wall to place the enhancement nozzles at the bottom of the tank. Normal maintenance and repair are only required for the power pump; the jet aerators require no maintenance and their performance does not degrade over long-term operation. 3. For renovation projects, the power pump and Venturi jet aerator are located outside the tank. The main pipe connecting the jet aerator outlet to the enhancement nozzles extends above the wall and then runs along the tank wall, connecting to the enhancement nozzles located at the bottom of the tank via branch pipes. Depending on the design size, the enhancement nozzles can be manually placed into the tank bottom or hoisted in. After positioning, the connecting pipe extending above the water surface is connected to the branch pipe on the main pipe. D. Summary The jet ozone dosing system consists of an oxygen source, a power pump, a venturi jet injector for primary mixing, and a bottom-mounted booster nozzle for secondary mass transfer. Valves and pipelines enable the system to adjust gas supply according to water quality, prevent backflow, and ensure safe and economical operation.

No power required, flood-resistant, and operational during blackouts. Drainage Jet Pump for Hydropower Plants Product Overview The drainage jet pump is a critical component in hydropower plant drainage systems, widely used for turbine cover drainage, powerhouse leakage drainage, and sump sediment removal. Powered by the energy of the working fluid itself—not plant auxiliary power—it can operate fully submerged. In blackout or emergency conditions, it continues to drain effectively, serving as a vital safeguard against powerhouse flooding. Why Choose a Drainage Jet Pump? Jet pumps have long been overlooked due to their relatively low efficiency (typically 28%–35%). In leakage and emergency drainage applications at hydropower plants, however, their safety redundancy often outweighs pure hydraulic efficiency. Key Advantages No Power Required — Operates During Blackouts The jet pump is driven by the energy of the working fluid and requires no electrical supply. When the plant loses auxiliary power, it continues to operate normally, effectively eliminating the risk of powerhouse flooding. Flood-Resistant — Fully Submersible The jet pump can be installed and operated fully submerged. Even if a valve misoperation floods the drainage system, it remains functional and rapidly mitigates the incident. Proven Emergency Drainage Equipment With a simple, stable design, it is ideally suited for emergency and contingency drainage, providing a final line of defense for powerhouse safety. Replaces Slurry Pumps for Sump Desilting The jet pump can remove accumulated sediment from collection sumps. Compared with conventional slurry pumps, it offers clear advantages: 1. Compact layout — installs directly inside the sump 2. Simple maintenance — no complex rotating machinery 3. Robust performance — air content in the water does not affect suction or desilting efficiency When a water turbine is used to agitate sediment at the sump bottom, variations in dissolved air content do not impair the jet pump’s suction or desilting performance. Applications Application Description Turbine Cover Drainage Removes leakage water from the turbine cover area Powerhouse Leakage Drainage Continuously removes water seeping into the powerhouse Sump Desilting Replaces slurry pumps to remove accumulated sediment Emergency Drainage Protects the powerhouse during blackouts or operational errors Design Notes for Sediment Removal When used to remove sediment from collection sumps, flow inside the pump is two-phase (liquid–solid). Performance equations, optimal area ratio, and other design parameters depend not only on conventional factors, but also on: 1. Concentration of the suction liquid 2. Specific weight of the suction liquid 3. Maximum particle size of the solids being conveyed Therefore, sediment-removal jet pumps must be designed using mud/slurry jet pump performance curves and dedicated calculation methods. Standard water jet pump formulas should not be applied directly. Product Comparison Feature Drainage Jet Pump Slurry Pump Conventional Electric Pump Power Required No Yes Yes Operates During Blackout Yes No No Submersible Operation Yes Limited Limited Emergency Drainage Capability Strong Moderate Weak Peak Efficiency ~28%–35% Higher Higher Installation Compact; direct sump mounting Larger footprint Dedicated pump room required Suitability Guide Recommended applications: 1. Powerhouse leakage drainage at hydropower plants 2. Continuous drainage when auxiliary power is unavailable 3. Emergency and contingency drainage systems 4. Sump sediment removal (requires dedicated design) Selection guidance: If safety redundancy, blackout protection, and emergency drainage are the priority, the drainage jet pump is the ideal choice.

Ejector Installation Guide Chengdu Chengdu GreenWater Co., Ltd. 1. Overview Venturi jet is a high-efficiency jet device. The working (power) fluid under pressure enters the injection chamber from the inlet of the jet to form a high-speed jet fluid. The high-speed fluid generates a pressure drop, causing the material to be added (liquid/gas) to be sucked in from the suction port and enter the working fluid. The mixed liquid reaches the outlet through the diffusion section, and the flow rate slows down and the pressure rises (but is lower than the inlet pressure). As long as there is a small pressure difference between the inlet and outlet, a negative pressure can be formed to suck in liquid or gas. The structure of the jet aeration system includes ejector, efficiency nozzle (secondary ejector), circulating water pump, etc. It is suitable for various water depths, maintenance-free, easy to install and construct, and can be constructed and modified without water discharge. The same set of equipment can use different gas sources such as air, fan-pressurized air or pure oxygen to meet processing load fluctuations. 2. Installation method 2.1 Installation outside the pool According to the water pump, the installation outside the pool is mainly divided into pipeline pump, vertical pump and self-priming pump dry installation. It is suitable for newly built or renovated above-ground aeration tank and underground aeration tank structures. The installation is very fast and convenient, and the pipeline is simple. Only the water pump needs to be maintained, and the ejector and booster nozzle do not require maintenance for long-term operation. Figure a: Horizontal pump dry installation Figure b: Dry installation of self-priming pump Figure c: Air blast and pressurized installation 2.2 Pipeline installation If the power water volume and pressure on the pipeline are within the working range of the selected ejector, the ejector can be installed directly on the main pipeline; when the power flow and pressure remain unchanged, the ejector will inhale a constant amount of gas or liquid. If the power flow on the main pipeline is greater than the working flow of the selected ejector, the ejector can be installed on the bypass, and the flow and pressure through the ejector can be adjusted through the main flow regulating valve to adjust the suction volume or liquid volume. 2.3 GWQ/B jet aerator installation form GWQ/B jet aerator is mainly composed of water pump, Venturi jet, efficiency nozzle and secondary jet guide tube (optional). The system is simple and does not require blowers, complex pipelines and other equipment; the structure is compact and easy to install. During maintenance, only the water pump is required to be repaired. Repairing one piece of equipment does not require stopping the operation of other equipment. GWQ: Submersible jet aerator, which can be hoisted into the pool; GWB: Dry installation outside the jet aeration tank. GWQ submersible jet aerator hoisting Dry installation outside GWB jet aeration tank 2.4 GW integrated jet aeration unit GW jet integrated equipment uses liquid as the working medium and uses the Venturi principle to generate negative pressure when the liquid is sprayed at high speed, so that the mixed liquid (sewage + sludge) sucked in by the water pump is jet-mixed with air/oxygen in the ejector to form a supersaturated oxygen mixed liquid. It is small in size, compact in structure and movable. It is suitable for various renovation or new aeration and oxygenation occasions. It can also be used in renovation projects where water is not stopped or water is discharged. 3. Self-priming height and suction port layout When the self-priming jet aeration jet is installed outside the pool, the height of the suction port of the jet should be higher than the water surface. If the ejector is installed inside the pool, or installed outside the pool but the height of the suction port is lower than the water surface, the suction port of the ejector needs to be extended above the water surface. 4. Arrangement of efficiency-enhancing nozzles in the aeration tank The service distance in the spray direction of the booster nozzle is generally 5 m to 6 m. When selecting, first determine the nozzle specifications and quantity according to the unit configuration table, and then filter according to the pool layout. 4.1 Pool width ≤ 6 m Arranging a row of synergistic nozzles in the width direction of the pool can meet the service distance in the spray direction; in the length direction of the pool, arrange the nozzle spacing allowed for each model (for example, N70 spacing ≤ 3.5 m, N70B/N70C/N60 spacing ≤ 3 m, N40/N30 spacing ≤ 2.5 m). 4.2 Pool width＞6m Multiple rows of synergistic nozzles need to be arranged in the direction of the pool width. The number of rows can be estimated according to N=pool width/5 m (rounded); after the number of nozzles is allocated according to the row number, check whether the spacing in the length direction of the pool meets the requirements. 5. Key points for startup and shutdown after installation After the correct installation is completed, the valve must be started and stopped according to the correct status, especially the blowing and pressurizing method to prevent air from entering the water pump body or water from the fan/air duct. 5.1 Self-priming jet aeration Startup: Start the water pump according to the water pump manual and confirm that it is running in the forward direction; the submersible pump can measure the wind speed at the self-suction port, and the motor rotation can be observed for the pump outside the pool; if the air suction port is obvious, the operation is normal. Shutdown: Stop the water pump according to the water pump manual. 5.2 Air blast and pressurized jet aeration The initial state after the equipment is installed: the water pump and fan are stopped; the blast air inlet valve FI is closed; the self-priming bypass valve SI is fully open; the blower vent valve FV is open. 1. When using the blast and pressurization mode to start the water pumps one by one, the self-priming bypass valve of the ejector of the unstarted water pump must be opened. 2. It is prohibited to use a blower alone to aerate through the jet without turning on the jet pump. 3. After confirming that the self-priming is working normally, open the blast air inlet valve FI and the blower, close the self-priming bypass valve SI, and gradually close the vent valve FV. 4. Shutdown: When the system shuts down, first turn on the SI exhaust, then stop the fan and turn off the FI, and finally stop the water pump; do not stop the water pump when the fan is running and FI is on. 5. When the blower is stopped, the ejector corresponding to the water pump that is not stopped/not started should close FI and open SI to prevent siphonage from causing pool water to enter the blast pipe. Valve opening and closing reference table Condition FO FV FI SI PI PO Water pump stops/fan stops close open close open close close Water pump on/fan off close open close open open open Water pump on/fan on open close open close open open Water pump stops/fan starts (fault) open close close open close close FO blower outlet valve; FV vent valve; FI blower air inlet valve; SI self-priming bypass valve; PI/PO water pump inlet/outlet valve. 5.3 Jet plus ozone After the equipment is installed, the water pump is stopped and the ozone inlet valve is closed. After starting the water pump and confirming that the self-priming is normal, close the self-priming air valve and then open the ozone air inlet valve. When stopping, first close the ozone inlet valve, then close the water pump and valve according to the instructions. 6. Pay attention to the installation site of pure oxygen/diving equipment Engineering practice (coking wastewater pure oxygen aeration test) shows: 1. After the oxygen supply equipment, busbar and starting cabinet are in place, the oxygen supply pipeline is laid, and the diffuser is lifted into the sewage pool with a crane; 2. In order to prevent the original air aeration pipe from being crushed, a support platform should be set up underwater; 3. When installing in water, it is recommended to turn off the blower briefly to eliminate the influence of water and air flow turbulence and ensure that the equipment is correctly positioned; 4. Oxygen-related equipment and pipelines must be cleaned and degreased according to the properties of oxygen, and must comply with oxygen pipeline installation specifications. 7. Installation of jet pump for foundation pit dewatering (related applications) 7.1 Light well points The jet pump and supporting centrifugal pump are arranged above the ground of the foundation pit: each well point pipe is connected to the suction port of the jet pump through the main pipe, and the centrifugal pump uses clean water circulation. The ultimate suction depth of the jet pump is about 10 m, and the normal precipitation depth is about 8 m. Installation and debugging process: Install the ground centrifugal pump, jet pump, water tank and ground pipeline; determine the well point layout, sink the well point pipe after drilling and fill it with sand filter material; test to ensure that the well point pipe does not leak air or water before putting it into use. 7.2 Jet well point (jet deep well pump) The jet pump is placed in the jet well pipe (integrated jet deep well pump), and the burial depth is determined according to the precipitation depth; the suction depth can usually be considered to be about 4 to 6 m lower than the jet pump, and a high-pressure water pump is generally required. Installation and debugging process: Install ground centrifugal pumps, water tanks and ground pipelines; determine the well point layout, sink the injection well point pipes after drilling and fill with sand filter material; test to ensure there is no air leakage or water leakage before putting it into use. 8. Troubleshooting related to installation The ejector itself cannot generate a pressure difference, but relies on the pressure loss of the power source through the ejector and the pipeline to form a pressure difference. When it cannot work normally, the installation position can be appropriately changed to meet the pressure difference requirements, and it is recommended to install pressure gauges at the inlet and outlet. 1. The inlet pressure is low and the pressure difference is not enough: increase the pump head or add a pressure pump; 2. The matching inlet and outlet connecting pipe is too small: use a pipe that is consistent with the inlet and outlet of the ejector; 3. There is a blockage in the connecting pipe: clear the blockage; 4. The suction pipe is dirty or blocked: blow it clean and remove the blockage; 5. Dimensional changes caused by internal dirt during long-term operation: usually soak in 30% hydrochloric acid for about 30 minutes to clean, and then rinse with clean water.

Jet Pump for Foundation Pit Dewatering In underground engineering projects, it is often necessary to artificially lower the groundwater level. When open ditch drainage with large-scale excavation is not suitable, well point dewatering is an excellent alternative, including light well points suitable for shallow drawdown and jet well points capable of drawdown depths exceeding 10 to 20 meters. I. Light Well Point Dewatering Light well point dewatering uses a jet pump with a supporting centrifugal pump arranged above ground level at the foundation pit (see Figure 1). Each well point pipe is connected to the suction inlet of the jet pump via a common header pipe, and the centrifugal pump circulates clean water. The ultimate suction depth of the jet pump is 10 meters, typically achieving a dewatering depth of approximately 8 meters. Figure (1) Light Well Point Dewatering System Flow Diagram 1.

Test to confirm that the well point pipes are free of air and water leaks before placing the system into operation. II. Jet Well Point Dewatering An alternative approach is jet well point dewatering, in which the jet pump is installed inside the jet well pipe (our company has integrated this into a single jet deep well pump unit). The burial depth of each jet deep well pump is determined based on the required dewatering depth (see Figure 2). Typically the suction depth (required dewatering depth) can be approximately 4 to 6 meters below the jet pump position. This type of jet pump generally requires a supporting high-pressure water pump.

How does a venturi injector work? Fluid with a certain pressure passes through the nozzle, converts hydrostatic energy into kinetic energy, forms a certain negative pressure, and at the same time transfers kinetic energy to the second fluid to achieve the purpose of sucking the second fluid. The two fluids are mixed in the ejector, and the mixed liquid is discharged after passing through the diffuser tube. The diffuser tube can reduce the flow rate of the mixed liquid and increase the static pressure to reduce losses. In this process, the requirements for fluid transportation and mass transfer are achieved. Working principle diagram of the jet (the energy of the jet comes from the difference between the power fluid pressure and the mixed fluid pressure) Core structure composition The structure of the jet is generally: nozzle, suction chamber, throat, diffuser tube.

Working Principle - Chengdu GreenWater - URL: https://cd-greenwater.com/english/how-ejector-creates-vacuum.html - Canonical: https://cd-greenwater.com/english/how-ejector-creates-vacuum.html - Language: en - Source: english/how-ejector-creates-vacuum.html - Description: A simple explanation of how an ejector uses motive fluid, nozzle, suction chamber, throat and diffuser to create a vacuum, plus key factors affecting vacuum level. How Does an Ejector Create a Vacuum? An ejector uses high-pressure motive fluid passing through a nozzle to form a high-speed jet. After the motive fluid accelerates, the static pressure near the nozzle exit and inside the suction chamber drops. When this pressure falls below the pressure in the vessel being evacuated, gas enters the ejector through the suction inlet. The entrained gas mixes with the motive fluid in the throat, then the mixed flow decelerates through the diffuser section, recovering part of its pressure before being discharged. As gas is continuously carried away, the pressure inside the evacuated vessel steadily decreases, thereby creating a vacuum. Four Steps of Vacuum Creation by an Ejector 1. Motive Fluid Enters the Nozzle Water, air, or steam at a certain pressure and flow rate enters the ejector. The motive fluid can be supplied by a pump, compressor, or steam system. 2. The Nozzle Converts Pressure into Velocity As the motive fluid passes through the converging nozzle, the flow area decreases, the velocity increases rapidly, and the static pressure drops simultaneously. The high-speed jet creates a low-pressure zone in the suction chamber. 3. The Low-Pressure Zone Draws in Gas When the pressure in the suction chamber is lower than the pressure inside the equipment or vessel being evacuated, the pressure differential drives gas through the suction inlet. The high-speed jet continuously entrains and carries away this gas, gradually reducing the number of gas molecules in the vessel and steadily lowering the internal absolute pressure. 4. The Mixed Flow Passes Through the Diffuser and Is Discharged The motive fluid and entrained gas exchange momentum and mix in the throat. After the mixed flow enters the gradually expanding diffuser section, its velocity decreases and part of the kinetic energy is converted into pressure energy, enabling the mixed flow to overcome the discharge back pressure and be expelled. The entire process can be summarized as: Motive fluid pressure energy → High-speed nozzle jet → Low-pressure zone formation and gas entrainment → Throat mixing → Diffuser pressure recovery and discharge Is Vacuum "Sucked" Out? Strictly speaking, an ejector does not directly create an empty cavity. Rather, it uses the pressure differential and high-speed jet to continuously remove gas from the vessel. When the rate at which gas is expelled exceeds the rate at which external air leaks in or process gas is generated, the pressure inside the vessel decreases, forming a sub-atmospheric vacuum condition. Therefore, the ultimate vacuum level an ejector can achieve depends on the balance between its gas extraction capacity and the system's air leakage, vapor generation, and other gas loads. Main Structural Components of an Ejector Component Function Motive Inlet Receives high-pressure water, compressed air, or steam Nozzle Converts pressure energy into a high-speed jet Suction Inlet Connects to the vessel or pipeline to be evacuated Suction Chamber Forms a low-pressure zone and receives the entrained gas Throat Allows momentum exchange and mixing of the motive fluid and entrained gas Diffuser Reduces flow velocity, recovers part of the pressure, and drives the mixed flow to discharge What Factors Affect Vacuum Level? 1. Motive Fluid Pressure and Flow Rate If the motive pressure or flow rate is insufficient, the nozzle cannot produce the design-specified high-speed jet, and the suction chamber pressure cannot be adequately reduced. 2. Nozzle and Throat Dimensions The nozzle exit area, throat area, and their ratio determine the ejector's gas extraction capacity, vacuum level, and allowable discharge pressure. If the dimensions are mismatched, an ideal vacuum may not be achieved even with high motive pressure. 3. Discharge Back Pressure Excessively narrow, long, or blocked discharge piping, or excessive downstream pressure, will impede the discharge of the mixed flow. When the back pressure exceeds the design range, gas extraction capacity drops, and in severe cases, vacuum may be lost entirely. 4. Suction Line Resistance Excessive suction line length, undersized pipe diameter, too many elbows, or insufficient valve opening all increase resistance, causing the vacuum measured at the equipment inlet to differ from the actual vacuum inside the evacuated vessel. 5. System Air Leaks Leaks at flanges, valves, seals, instrument connections, or welds continuously introduce outside air into the system. If the leakage rate is too high, the ejector may never reach the target vacuum level. 6. Gas Properties and Temperature The molecular weight, temperature, moisture content, and condensability of the gas being extracted all affect ejector performance. When using steam ejectors, the quality of the motive steam and the condensation conditions are also critically important. Why Don't Ejectors Need Moving Parts? Ejectors do not rely on impellers or pistons to extract gas. Instead, they use the energy of the motive fluid itself to accomplish acceleration, entrainment, and transport. Consequently, the ejector body typically has no moving parts, offering advantages such as simple construction, low maintenance, and the ability to handle wet or corrosive gases. However, "no moving parts" does not mean no energy is consumed. The motive water, compressed air, or steam must all be supplied by external systems, and their energy consumption should be accounted for in the overall vacuum system calculation. What If the Ejector Cannot Establish a Vacuum? Check the following in sequence: 1. Whether the motive fluid pressure and flow rate meet the design values; 2. Whether the motive fluid valve and suction inlet valve are properly opened; 3. Whether the nozzle, throat, or discharge piping is blocked; 4. Whether the discharge back pressure exceeds the allowable range; 5. Whether the suction line and the evacuated system have air leaks; 6. Whether the vacuum gauge range, installation position, and readings are correct; 7. Whether the actual gas load exceeds the ejector's design extraction capacity; 8. Whether the nozzle is worn, corroded, or scaled. Frequently Asked Questions What is the difference between an ejector and a vacuum pump? A mechanical vacuum pump expels gas through rotating or reciprocating components; an ejector uses a high-speed motive fluid to entrain gas. Ejectors have a simpler construction but require a continuous supply of motive fluid. What motive fluids can be used in an ejector? Common motive fluids include pressurized water, compressed air, and steam. The choice should be based on the target vacuum level, extraction capacity, gas properties, on-site energy availability, and material requirements. Does higher motive pressure always mean a higher vacuum level? Not necessarily. An ejector needs to operate near its design operating point. While excessively low motive pressure degrades performance, blindly increasing pressure may only increase energy consumption without further improving the vacuum level. The nozzle, throat, gas load, and discharge back pressure must all be mutually matched. Can an ejector achieve absolute vacuum? No. In any real system, gas loads, leaks, flow losses, and equipment performance limits always exist. In engineering practice, the target should be expressed as an absolute pressure or a vacuum level under specified conditions; "vacuum" should not be interpreted as pressure equal to zero. Conclusion The core mechanism by which an ejector creates a vacuum is: allowing the motive fluid to form a high-speed jet through the nozzle, establishing a low-pressure zone in the suction chamber, and continuously entraining, mixing, and discharging the gas being extracted. Whether the target vacuum level can be achieved depends not only on the motive pressure, but also on the nozzle and throat geometry, gas extraction load, suction resistance, discharge back pressure, and system airtightness.

How to inject ozone using a venturi injector? Working principle A venturi injector (also called a high-efficiency jet injector) is a gas–liquid mixing device. Pressurized motive water enters the injector, jets through a nozzle and converts static pressure into high velocity. The high-speed jet creates vacuum at the suction port, which draws ozone gas (or ozone off-gas / oxygen / air) into the motive flow and mixes it instantly. The mixture then passes through a divergent diffuser, slows down, recovers part of the static pressure, and discharges. Two-stage mass transfer 1. Primary injection (venturi): Ozone is sheared into fine micro-bubbles at the throat; mass transfer starts almost simultaneously with suction. 2. Secondary ejection (efficiency-plus nozzle): The mixture is piped to bottom nozzles and ejected at high speed, entraining about 4–5 times its own flow of tank water for further mixing and transfer. Medium-scale clean-water tests with a GW200 injector (DN50) showed oxygen transfer efficiency above 90% (pure oxygen) and ozone utilization above 99%. How to connect and operate Typical connection： 1. Motive loop: circulating pump → venturi injector inlet → mixed-flow outlet → contact tank / secondary nozzles. 2. Gas side: ozone generator outlet → injector suction port (ozone-compatible piping required). Start / stop sequence for ozone injection 1. Initial state: pump OFF, ozone inlet valve CLOSED. 2. Start the pump and confirm self-suction / air draw is normal. 3. Close the self-suction air valve, then OPEN the ozone inlet valve. 4. To stop: CLOSE the ozone inlet valve first, then shut down the pump and valves per the manual. Design factors that control transfer 1. Gas-to-water ratio: smaller ratio → higher ozone transfer efficiency (but needs more circulating water / pump power). 2. Water depth: deeper water → higher transfer efficiency (higher civil cost). 3. Injector inlet pressure: higher inlet pressure → higher transfer efficiency (higher pump power). 4. Material: use ozone-resistant stainless steel such as 316 / 316L.

Step-by-Step Startup Guide - Chengdu GreenWater - URL: https://cd-greenwater.com/english/how-to-prime-a-jet-pump.html - Canonical: https://cd-greenwater.com/english/how-to-prime-a-jet-pump.html - Language: en - Source: english/how-to-prime-a-jet-pump.html - Description: How to prime a well jet pump: power-off checks, water filling, air venting, startup observation, repeat filling, and common priming failure causes. How to Prime a Jet Pump? Quick Answer: To prime a well jet pump, fill the pump casing and suction pipe with as much clean water as possible through the priming port on the pump body before starting, and expel all air. After closing the priming port, start the pump briefly and observe the pressure and water output. If a stable water flow is not established, stop the pump immediately, add more water and vent air again. Never let the pump run dry for an extended period. Note: The priming procedure described in this article applies to shallow-well or deep-well jet pumps equipped with a motor, impeller, and jet assembly. Industrial eductors or ejectors have no impeller and typically rely on an external motive fluid supply; they do not use the same priming method. What to Prepare Before Priming Clean water compatible with the pump system; A funnel or clean fill hose; A wrench for removing and reinstalling the priming plug; The pump manufacturer's instruction manual; Appropriate gloves and safety goggles. Before starting, verify that the suction pipe, fittings, check valve, or foot valve are properly installed. If the suction side has air leaks or the check valve has failed, the pump may fail to prime even after repeated water filling. Jet Pump Priming Steps 1. Cut Off Power Turn off the pump power supply and confirm that the equipment cannot start unexpectedly. Do not remove the priming plug or inspect the pump body while the motor is energized. 2. Release System Pressure Open a nearby faucet or drain valve to release residual pressure in the piping. Confirm that the pressure gauge has returned to zero before operating the priming port. 3. Open the Priming Port Locate the priming plug or priming port on top of the pump casing and carefully remove it. The location may vary between models — always consult the manufacturer's manual first. 4. Slowly Add Clean Water Slowly pour water through the priming port, allowing it to fill the pump casing and suction pipe. Wait for air bubbles to escape and continue adding water until the water level near the priming port no longer drops noticeably. Deep-well jet pumps or systems with long suction pipes may require multiple rounds of refilling. Do not use water containing sediment, debris, or corrosive substances for priming. 5. Reinstall the Priming Plug Once the pump body is confirmed to be full of water, reinstall and tighten the priming plug. The seal must be reliable, but avoid over-tightening, which can damage the threads or sealing components. 6. Start the Pump Briefly Restore power and start the pump, observing the pressure gauge and water outlet. Under normal conditions, the pump will gradually build pressure and produce a continuous, stable water flow. 7. Stop Immediately If No Water Appears If no water is discharged within a short time, the pressure does not rise, or the pump makes unusual noises, stop the pump immediately. Once the equipment is safe, reopen the priming port and add more water while venting air again. Never allow a jet pump to run without water. Dry running can damage the mechanical seal, impeller, and other components. The allowable trial-run duration should follow the equipment manual. Why Does a Jet Pump Still Fail to Draw Water After Priming? Common causes include: 1. Suction pipe air leaks: Leak points exist at fittings, sealant tape, piping, or the pump casing; 2. Foot valve or check valve failure: Water drains back into the well after shutdown and the pump body cannot remain filled; 3. Water level too low: The actual suction lift exceeds the jet pump's working range; 4. Suction pipe blockage: The strainer, foot valve, or piping is clogged with sediment and debris; 5. Inadequate priming: Significant air remains inside the pump casing or suction pipe; 6. Incorrect pressure switch or valve settings: The discharge valve is closed or the control system is not functioning properly; 7. Nozzle or venturi assembly clogged: Scale, sediment, or foreign matter impairs jet suction; 8. Damaged impeller or mechanical seal: The pump cannot build the required pressure or continuously draws in air. If water flow cannot be established after repeated priming attempts, stop trying and inspect the suction-side airtightness, foot valve, well water level, and jet assembly. If the cause cannot be identified, contact a pump service technician. Frequently Asked Questions Does a jet pump need to be primed before every start? In a properly sealed system with a well-functioning check valve, priming is normally required only after initial installation or after maintenance that drains the system. Routine daily startups should not require adding water each time. If the pump frequently loses its prime, investigate air leaks or water backflow issues. Can I let the jet pump run dry to self-prime? Not recommended. Most well jet pumps must be filled with water before starting. Prolonged dry running can overheat the mechanical seal and damage the pump. How much water is needed for priming? There is no standard volume. Fill the pump casing and suction pipe as fully as possible until the water level at the priming port stabilizes. Systems with long piping or deep wells typically require more water and multiple refills. Do industrial eductors need to be primed this way? Typically not. An industrial eductor body has no impeller; it relies on an external pump or other pressure source to supply motive fluid. At startup, first confirm that the motive fluid has reached the specified flow rate and pressure, then vent air, open valves, and commission according to the system operating procedures. Conclusion The key to priming a jet pump is: cut power first, fill the pump casing and suction pipe with clean water, thoroughly expel all air, seal the priming port, then start briefly and observe. If a stable water flow cannot be established, stop and inspect immediately to avoid dry running the pump. Different brands and models vary in construction, valve positions, and allowable trial-run duration. Always follow the equipment manufacturer's instruction manual for actual operation.

Application of jet aeration in grease wastewater treatment engineering Grease wastewater has high organic load and large operation fluctuations. Once the oxygen supply of the aeration system is insufficient or degrades for a long time, it will often cause chain problems such as unstable water output, high energy consumption, and frequent maintenance. Jet aeration is based on "high oxygen utilization + more reliable structure + more convenient maintenance" to provide a more stable oxygenation capacity for the oil wastewater biochemical section, and through transformation to achieve continuous cost reduction and stable compliance with standards. Why grease wastewater needs more reliable oxygen supply 1. Insufficient oxygen utilization: the oxygenating capacity is insufficient and the water output is easy to fluctuate. 2. Easily clogged/corroded: The longer the mesopore aeration pipe runs, the more obvious the clogging, rust and corrosion will be, and the efficiency will continue to decline. 3. Frequent maintenance affects continuous production: The maintenance cycle of mechanical aeration equipment is short, and water outage maintenance will affect the stability of subsequent processes. 4. Weak impact resistance: unstable processing effects are more likely to occur when the load fluctuates. Solution: Jet Aeration Transformation Ideas The original combined oxygen supply method of "compressed mesopore aeration + mechanical aeration" was upgraded to "compressed pressurized jet aeration". Jet aerators and synergistic nozzles are arranged in the aeration tank to achieve higher oxygen utilization and more stable oxygenation performance through jet flow, while simplifying the system and reducing the risk of performance degradation caused by clogging and corrosion. Program features 1. More efficient oxygenation: high oxygen utilization rate, improved oxygen supply capacity, and more stable water output. 2. More stable long-term operation: the pipeline system is relatively simple, reducing clogging, rust and corrosion, and the oxygenation performance is not easy to decay. 3. More convenient maintenance: the water pump and ejector can be installed outside the pool; the ejector and the synergistic nozzle are maintenance-free, and the water pump is mainly maintained; there is no need to stop and drain the water for maintenance.4. Lower noise and energy consumption: it can replace mechanical surface exposure machines and provide a better overall operating experience. Case verification Project background: The oil wastewater of a certain oleochemical enterprise is treated by biological methods. The process is grille-anaerobic digestion-primary aeration tank-secondary aeration tank-effluent. The original aeration system was a combination of mechanical surface aerator and compressed mesopore tube aeration, which had problems such as low oxygen utilization, insufficient oxygenation, easy clogging and corrosion, frequent maintenance, and unstable water output. Later, ejector was used to transform the oxygen supply equipment of the two-stage aeration tank. Treatment water volume: about 360m³/d Water inlet and outlet results (mg/L): BOD₅：2000 → 25 CODcr：4500 → 70 TKN：200 → 3 Comparison of energy consumption and installed capacity (quantifiable transformation results) 1. Installed power before transformation: 44kW (surface exposure machine 11kW × 4)2. Installed power after transformation: 30 kW (GW jet aeration 7.5kW × 4)3. The installed power is reduced: 14kW, and the operating cost is significantly reduced. 4.Unit energy consumption: Energy consumption per 1 kg/COD degraded is reduced from 0.61kWh to 0.45kWh. Implementation configuration reference (from case) 1. Primary and secondary aeration tanks: A total of 4 GW400 jet aerators are used. 2. Each jet: equipped with 4 N40 booster nozzles. 3. Matching water pump: head 15m, flow 100m³/h, power 7.5kW (single set). Applicable scenarios 1. The oil and fat wastewater biochemical section has insufficient oxygen supply and fluctuates water output, making it difficult to reach standards stably. 2. The mesoporous aeration pipe is seriously blocked/corroded, and the aeration efficiency continues to decrease. 3. The surface exposure machine has a high failure rate and frequent maintenance, which affects continuous production.4. It is necessary to achieve "stable compliance with standards + reduction of energy consumption + reduction of operation and maintenance" through transformation. Frequently Asked Questions (FAQ) Q1: Why will the water flow be more stable after modification? A: Jet self-priming/pressurized jet aeration can provide more stable oxygenation capacity, and the system is less susceptible to efficiency degradation due to clogging and corrosion, thereby improving the long-term operation stability of the biochemical section. Q2: Will the maintenance workload be greater? A: The case shows that the water pump and ejector can be installed outside the pool, and the ejector and booster nozzle are maintenance-free.

Advantages of jet aerators in aerobic processes oxygen utilization rate and maintenance costs Jet aerators combine the advantages of high oxygen transfer efficiency, energy savings, and easy installation. They can significantly reduce both operating and capital costs, while also reducing the required footprint by increasing sludge concentration and sludge loading. Advantages of Jet Aerators: 1. Jet aerators provide very high oxygen transfer efficiency, which can reach 30% to 45% depending on water depth. Since water depth is not a limiting factor, they can achieve excellent power efficiency. In engineering practice, the theoretical power efficiency can reach up to 6.4 kg(O2)/kWh, greatly reducing the operating cost of wastewater aeration. 2. The piping layout and installation requirements of jet aerators are very simple, which minimizes piping and installation expenses and therefore lowers equipment investment costs. 3. Jet aerators can significantly increase sludge concentration, with MLSS exceeding 5000 mg/L, as well as improve sludge loading. This helps save land area and reduce civil construction investment.

Covers working principles, advantages over diffused aeration. Complete Analysis Of Jet Aerator When many people first hear the term "jet aerator," their immediate reaction is often: how is it different from ordinary aerators? You can think of it as an aeration method that excels at "air intake, mixing, stirring, and oxygen transfer." It doesn't simply pump air into the water; instead, it uses a high-speed water flow to draw in air, pure oxygen, and even ozone, and then, through jetting and circulation, allows the gas to more fully enter the water body. To put it more bluntly, the real strength of a jet aerator lies not only in its ability to aerate, but also in its ability to perform air intake, mixing, circulation, and mass transfer all at once. I. How Does a Jet Aerator Work? If we break down its working process, it can be basically divided into two steps. The first step is to spray the water quickly. Under the action of the pump, the water is ejected at high speed through the nozzle, converting pressure energy into velocity energy. At this time, a negative pressure zone is formed inside the ejector. Air or oxygen is "drawn" in by this negative pressure and then mixes with the high-speed liquid flow inside the ejector to form finer and more uniform bubbles. The second step is to send the mixed water and air to the bottom of the pool and then spray it out. At this point, the jet not only propels itself forward, but also carries more surrounding water, creating a significant circulation, mixing, and entrainment effect. This allows for more thorough contact between oxygen and the wastewater and sludge, resulting in higher oxygen transfer efficiency. Therefore, the core logic of jet aerators is not "bubbling," but rather "high-speed ejection + forced mixing + secondary injection + circulating mass transfer." This is also the biggest difference between it and many traditional aeration methods. Structure diagram: II. Why is it more attractive than traditional aeration? a. Higher Oxygen Transfer EfficiencyThe finer and more evenly distributed the bubbles, the easier it is for oxygen to enter the water.Existing data indicates that self-priming and pressurized jet aeration systems can achieve oxygen utilization rates of 30% to 45% under suitable operating conditions; pure oxygen jet aeration achieves even higher rates, exceeding 90%; and in ozone application tests, ozone utilization rates can even reach over 99%.This is crucial for wastewater treatment projects. Higher oxygen supply efficiency allows for smoother system operation and more stable treatment results. b. Not just aeration, but also mixing and circulation.Many problems in wastewater treatment plants are not just insufficient oxygen, but also uneven mixing, dead zones, and poor sludge suspension.Jet aerators, because of their significant jetting and entrainment capabilities, can often perform mixing, circulation, and aeration all at once. This capability is very practical for tank types such as oxidation ditches, plug flow tanks, mixing tanks, and oxidation ponds. c. The system is relatively simple and more flexible in modification. Taking the GWQ/B jet aerator in the documentation as an example, the system mainly consists of a water pump, a Venturi jet aerator, enhancement nozzles, and necessary piping, with a relatively compact overall structure. For blower-pressurized solutions, it can also be upgraded by combining it with the existing blower or compressor system. In other words, many projects do not require a complete overhaul of the entire system; instead, performance can be improved based on the existing foundation. 4. Easier MaintenanceTraditional aeration heads are prone to clogging, aging, and cracking after prolonged use, often requiring water outages and drainage for repairs.Existing data repeatedly mentions that jet aeration systems are more suitable for retrofitting without water outages or drainage, with maintenance focusing more on equipment such as pumps. This is particularly significant for many older wastewater treatment plants, as it directly impacts the difficulty of repairs, downtime, and operating costs. 5. Lower noise and more adaptable to changing operating conditions. The information states that, under certain installation methods, jet aeration systems have relatively low noise levels, with some even approaching silence. Furthermore, it can switch between air, fan air source, or pure oxygen source according to load changes, and can also adapt to different operating conditions through frequency conversion regulation. Therefore, the system is usually more adaptable when facing fluctuations in water volume and quality. 6. There are also some additional benefits to the process operation. The data on pure oxygen jet aeration also mentions that this type of system can reduce foam and odor, improve sludge settling properties, reduce the risk of sludge bulking, and help improve the treatment capacity of existing wastewater treatment plants. These additional advantages are even more pronounced in scenarios with higher requirements, such as high-concentration wastewater, ozone exhaust gas reuse, and pure oxygen aeration. III. Where are jet aerators generally used? Based on the information gathered this time, jet aerators have a wide range of applications, not just traditional sewage tank aeration. 1. Municipal sewage and industrial wastewater treatment: This is the most common and core application area. Existing case studies and data cover a wide range of wastewater types, including domestic sewage, pharmaceutical wastewater, landfill leachate, dyeing and printing wastewater, food processing wastewater, papermaking wastewater, coking wastewater, alcohol wastewater, and chemical wastewater. Any project requiring improved oxygen supply efficiency, enhanced mixing within the treatment tank, and reduced downtime for retrofitting is well worth considering. 2. Pure oxygen aeration and high-load enhanced treatment If the project itself has a high load, tight treatment targets, and limited pool capacity, then pure oxygen jet aeration will be particularly valuable. It can inject pure oxygen into the water more efficiently, making it suitable for upgrading, expansion, and high-concentration organic wastewater treatment. 3. Ozone dosing and ozone exhaust gas reuse This document contains a great deal of information related to ozone, including design guidelines and numerous engineering achievements. This indicates that jet injectors already have a relatively mature application foundation in scenarios such as ozone dosing, ozone exhaust gas reuse, and enhanced oxidation. This type of capability is very attractive for advanced treatment projects. 4. River reoxygenation, iron and manganese removal, and water supply pretreatment Besides wastewater treatment plants, jet injectors can also be used for reoxygenation of rivers and lakes, removal of iron and manganese from groundwater, and oxygenation of water supply systems. Because its essence is to enhance gas-liquid mixing and mass transfer, it can be used as long as there is a need in the scenario to "deliver gas into liquid more efficiently". 5. Air flotation, chemical dosing, vacuuming, and industrial mixing Although these are not all "aeration" in the strict sense, the underlying logic is the same: they all utilize the ejector's ability to induce and mix air.Its engineering achievements also show that it has been used in industrial applications such as air flotation aeration, liquid-gas jet vacuum pumps, reagent dosing, tank circulation mixing, and powder and gas transportation. In other words, it is essentially not just an aeration device, but more like a fluid mixing platform. Engineering drawings： IV. How to understand its true engineering value From an engineering perspective, the true value of jet aerators lies not just in having a higher performance on a single parameter, but in their ability to integrate previously separate functions such as oxygen supply, mixing, circulation, and agitation into a single fluid system. The benefits of this are straightforward: 1. More compact system 2. More flexible modification ideas 3. Easier to balance mixing and oxygen transfer 4. Relatively less operational and maintenance pressure Especially for older wastewater treatment plants, if the original aeration heads have deteriorated, the air volume is insufficient, and the oxygen supply in the tank is uneven, then jet aeration is often not as simple as "replacing the equipment", but rather a route to improve efficiency and upgrade. V. Summary In short, jet aerators are a highly efficient aeration technology based on Venturi jet injection and secondary jet-enhanced mass transfer. Its real advantage lies not only in rapid oxygenation but also in its ability to simultaneously complete air intake, mixing, circulation, and agitation. Therefore, it is highly adaptable to various scenarios, including municipal sewage, industrial wastewater, pure oxygen aeration, ozone dosing, and river reoxygenation. If a project faces requirements such as upgrading standards, expanding capacity, noise reduction, reduced maintenance, and improved oxygen utilization, then jet aerators are indeed a technology route worthy of serious evaluation.

Jet Aerator Why Use Jet Aerator? Currently, the most common method of aeration is the blower system. However, after prolonged operation, issues such as aging, cracking, and clogging of the aeration heads, as well as wear and tear on the blowers, often arise. To account for these factors, blower capacity is typically oversized during the design phase. Additionally, traditional aeration equipment requires annual maintenance, which involves shutting down the system and draining the water—a process that is both complex and costly. Furthermore, as the volume of treated water increases and load fluctuations occur, this often leads to problems such as insufficient oxygen supply. Principle of Jet Aerator To address this issue, Chengdu Greenwater Technology Co., Ltd. has developed a jet aerator, which is primarily used in the biological aeration process for treating municipal sewage and industrial wastewater. The jet aerator mainly consists of water pump, Venturi Injector, energy-enhancing nozzle, secondary jet guide tube (optional). After the mixed liquid (sewage + sludge) is drawn in by the water pump, it undergoes jet mixing with air/ oxygen within the Venturi jet mixer to form a supersaturated oxygen-water mixture. This mixture is then jetted through a set of energy-enhancing nozzles into the tank or secondary jet guide tube. The secondary jet generated by the energy-enhancing nozzles recovers the pump’s energy, creating a flow effect in the tank or guide tube equivalent to five times the pump’s flow rate, thereby facilitating the process of hydraulic circulation and oxygenation within the tank. This characteristic enhances the efficiency of oxygen transfer in water, thereby significantly improving oxygen utilization and the kinetic efficiency of oxygen transfer, and ensuring the required dissolved oxygen concentration in the mixed liquor for the efficient treatment of industrial and domestic wastewater. Jet Aerator Pic： Advantages of Jet Aerator： 1. High oxygen utilization and high power efficiency, with no decline over time. 2. Maintenance can be performed without interrupting water flow, making repairs convenient and cost-effective. 3.

Existing blower/compressor systems can be utilized for pressurized jet aeration, significantly improving oxygen utilization. 5. Combining blower systems with jet aeration can significantly reduce operational energy consumption. 6. Enhanced resistance to shock loads. 7. Eliminates the complex piping of traditional blower systems; maintenance is convenient and cost-effective without the need to shut down water supply Applications of Jet Aerator： Jet aerator are suitable for various wastewater treatment applications, including push-flow aeration tanks, mixed-flow aeration tanks, extended-retention-time aeration tanks, oxidation channels, and oxidation ponds.

Jet aerator printing and dyeing wastewater treatment case In the field of printing and dyeing wastewater treatment, the stability and oxygenation efficiency of the aeration system directly affect the biochemical treatment effect, operating energy consumption and subsequent maintenance costs. For many sewage treatment stations that have been in operation for many years, traditional microporous aeration devices often suffer from problems such as blockage, cracking, and reduced efficiency after long-term use, which in turn affects the compliance of water output and the stable operation of the system. In response to the pain points of this industry, the application of jet aerators in printing and dyeing wastewater treatment renovation projects has demonstrated strong engineering adaptability and practical operation value. A small and medium-sized printing and dyeing wastewater treatment renovation project implemented by Chengdu Chengdu GreenWater Co., Ltd. in Changzhou, Jiangsu Province is one of the more representative cases. The original aeration tank of this project used a microporous aeration device. However, as the use time increased, the microporous tubes gradually aged and appeared clogging and cracking, resulting in a decrease in aeration efficiency and difficulty in achieving the design specifications. At the same time, when the original system is overhauling and replacing the microporous aeration device, the water needs to be stopped and drained, and the sludge must be re-cultivated after the overhaul is completed. Not only does it take a long time, but the maintenance cost is high, which puts great pressure on the customer's daily operation and management. Project diagram Against this background, the project party chose to use jet aerators to transform the original system. Compared with traditional microporous aeration methods, jet aerators have obvious advantages in installation methods, operation and maintenance, and system adaptation. The system is mainly composed of water pumps, connecting pipes, ejectors and synergistic nozzles. The pipeline layout is relatively simple, and it can realize non-stop and discharge installation, which greatly reduces the impact of the transformation process on the operation of the original sewage treatment system. From the perspective of process design parameters, the project's designed water treatment volume is 3000m3/d, and the aeration time is 24h. The size of the aeration tank is 40m×19.5m×5.4m, divided into 5 grids, with a super height of 0.6m and an MLVSS of 2500mg/L. The designed inlet water COD is 800~1200mg/L, and the design outlet water requirement is ≤100mg/L. Based on the actual needs of the project and equipment performance parameters, 4 sets of GW3600 jet aerators were finally selected, equipped with 108 N40 efficiency-enhancing nozzles. One set of GW3600 is equipped with a 37kW water pump, with a flow rate of 550m3/h, and a lift of 15m; the other three sets are equipped with a 30kW water pump, with a flow rate of 480m3/h , and a lift of 14m. This selection method is not standardized, but customized according to the project pool type, water volume, water quality and customer requirements. Because of this, the jet aerator can not only meet the aeration and oxygenation needs, but also take into account the mixing effect in the pool, avoid waste of energy consumption, and achieve an effective match between equipment configuration and treatment goals. Judging from the actual operating results, after the equipment was put into operation, the water treatment volume of this project remained at 3000m3/d. The measured COD of the incoming water is 800-1000mg/L, and the COD of the effluent is stable at ≤80mg/L, which is better than the original designed effluent index. The total power used by the project is 127kW, the corresponding COD degradation amount is 2.16~2.76t/d, and the unit degradation energy consumption is 1.41~1.1kWh/kgCOD. It can be seen from these operating data that the jet aerator can not only meet the treatment effect requirements in the printing and dyeing wastewater treatment renovation project, but also has good energy consumption control performance. In addition to treatment effect and energy consumption performance, jet aerators also have obvious advantages in terms of operational stability and maintenance convenience. After the project is put into operation, the mixing and oxygenation in the aeration tank will be more uniform, and there will be no dead zones, which will help maintain the stable operation of the biochemical system. At the same time, the jet aerator has low noise, successfully solving the problem of high noise in the original blast aeration system and improving the on-site operating environment. More importantly, the ejector and water pump are installed outside the pool, so installation and maintenance can be completed without stopping or draining water, significantly reducing the risk of downtime. From a maintenance perspective, the ejector and booster nozzle themselves require little maintenance, and only require regular maintenance of the water pump. This is in sharp contrast to traditional microporous aeration systems. Once the traditional microporous aerator is clogged or aged, it will not only be complicated to repair, but will also affect the operation of the entire pool. The core components of the jet aerator have low maintenance requirements, small maintenance workload, and the comprehensive maintenance cost of long-term operation is significantly lower. This is especially important for printing and dyeing enterprises, because continuous and stable production usually means that the sewage treatment system must maintain a high online rate and reliability. From the perspective of industry application, printing and dyeing wastewater has the characteristics of large fluctuations in organic matter concentration, obvious changes in treatment load, and high requirements for aeration and mixing. Simply relying on traditional aeration methods is often prone to problems such as insufficient oxygenation, local dead zones, and difficulty in maintenance after the equipment ages or the working conditions change. The jet aerator can better adapt to the complex working conditions in printing and dyeing wastewater treatment through the synergy of "oxygenation + stirring", and is especially suitable for project scenarios such as upgrading and renovation of old sewage stations, updating aeration systems, and projects that require non-stop production and renovation. Based on this case, it can be seen that the application value of jet aerator in printing and dyeing wastewater treatment is mainly reflected in the following aspects: first, flexible installation, which can realize non-stop water discharge construction; second, uniform mixing and oxygenation, which helps to reduce the aeration dead zone; third, low noise, which improves the on-site operating environment; fourth, the maintenance workload is small, which significantly reduces the cost of later maintenance; fifth, the water output is stable and can meet the first-level requirements of the national comprehensive sewage discharge standard. For companies that are upgrading printing and dyeing wastewater treatment, building new sewage station facilities, or planning to replace the original microporous aeration system, jet aerators provide a solution that takes into account treatment effects, maintenance convenience, and comprehensive operating costs. Especially as environmental protection standards continue to improve and companies pay more attention to stable compliance and energy conservation and consumption reduction, choosing aeration equipment suitable for actual working conditions has become one of the key factors for the success or failure of industrial wastewater treatment projects. If you are paying attention to the application of jet aerators in printing and dyeing wastewater treatment, or want to know more about the aeration transformation plan that is more suitable for your own project, equipment selection and system design based on specific water volume, water quality and tank conditions will be more helpful in improving project operation effects and investment returns.

Why Are More and More Slaughterhouse Wastewater Projects Choosing Jet Aerators In practical engineering applications, the SBR process is widely used for slaughterhouse wastewater treatment because of its compact flow arrangement, strong resistance to shock loads, and flexible operation. In the aeration stage of SBR tanks, jet aerators are gradually becoming the preferred equipment solution for more and more projects. 1. What Requirements Does Slaughterhouse Wastewater Treatment Place on Aeration Systems? Slaughterhouse wastewater treatment conditions usually have the following characteristics: 1. High concentration of organic pollutants, requiring strong oxygen supply capacity; 2. High content of suspended solids and grease, requiring better equipment adaptability; 3. Concentrated discharge periods with obvious instantaneous flow variation; 4. The system must ensure treatment performance while also maintaining long-term operational stability. This means that if a conventional aeration method is insufficient in mixing performance, anti-clogging capability, or maintenance convenience, problems are likely to appear during long-term operation. Especially for small and medium-sized slaughterhouse wastewater treatment projects, users are often more concerned about whether the equipment is stable, worry-free, and easy to maintain. 2. Advantages of Jet Aerators in the SBR Process Jet aerators use high-speed liquid flow to create negative pressure and draw in air, allowing efficient air-water mixing and achieving both oxygen transfer and mixing. When applied in slaughterhouse wastewater SBR systems, they usually offer the following advantages: 1. High oxygen transfer efficiency, helping improve aerobic biological treatment performance; 2. Strong mixing capacity, promoting full contact between sludge and oxygen in the tank; 3. Good adaptability to fluctuating operating conditions, making them suitable for intermittent discharge characteristics of slaughterhouse wastewater; 4. Easy maintenance, with pumps and major components arranged outside the tank; 5. Low clogging risk, suitable for wastewater environments with high suspended solids; 6. Lower noise, improving on-site operating conditions; 7. Simple system configuration, convenient for management and maintenance. For enterprises pursuing stable compliance and long-term operating economy, jet aerators are not only a type of aeration equipment, but also an engineering solution that balances treatment performance and ease of management. 3. Application Overview of an SBR Project for Slaughterhouse Wastewater In one slaughterhouse wastewater treatment project, the wastewater mainly came from pre-slaughter and post-slaughter washing, meat and organ cleaning, and equipment and floor washing. The wastewater had high organic content, high suspended solids, and concentrated discharge periods, making it a typical industrial wastewater with highly fluctuating conditions. 1. The project adopted the aerobic SBR treatment process and used GWB jet aerators in the aeration stage. 2. After model selection and configuration based on tank parameters and operating conditions, the system showed good oxygen supply and mixing performance in actual operation, with stable effluent indicators that met treatment requirements. From the engineering application results, the use of jet aerators in slaughterhouse wastewater SBR tanks not only ensured treatment performance, but also reduced equipment maintenance difficulty, demonstrating strong practical value. 4. Why Do Companies Care More About Aeration Equipment with Stable Operation? For wastewater treatment projects, equipment procurement is only the first step. What truly determines the project experience is long-term operational stability. When selecting equipment, many users increasingly focus on the following questions: 1. Is the equipment prone to clogging? 2. Is maintenance convenient? 3. Is the aeration performance stable? 4. Can the system adapt to fluctuations in water quality and flow? 5. Is long-term operation and management complicated? Jet aerators are receiving attention in the slaughterhouse wastewater field precisely because they perform well in these aspects. Especially for enterprise users that require stable long-term operation, choosing suitable aeration equipment can effectively reduce downtime and maintenance risks while improving overall system efficiency. 5. Selection Suggestions for Slaughterhouse Wastewater Treatment Equipment If your project falls into one of the following categories, the SBR process plus jet aerator solution is worth considering: 1. Slaughterhouse wastewater projects with large flow variation; 2. Industrial wastewater projects with high organic concentration and high suspended solids; 3. Retrofit projects aiming to reduce clogging and maintenance risks; 4. Small and medium-sized wastewater stations that emphasize stable operation and easy management. Depending on treatment scale, tank size, operating cycle, and effluent requirements, the model of the jet aerator, nozzle configuration, and supporting pump parameters will also vary. In actual selection, the design should be tailored to project conditions to balance oxygen supply capacity, circulation effect, and operational economy. 6. Conclusion In slaughterhouse wastewater treatment systems, selecting suitable aeration equipment is a key step in ensuring treatment performance and operational stability. When used together with the SBR process, jet aerators can provide advantages such as high oxygen transfer efficiency, strong mixing performance, easy maintenance, and low clogging risk, offering enterprises a more reliable wastewater treatment solution.

Factors in selecting jet aeration systems Under conditions where the oxygen demand has been determined, jet aerator selection is an optimization process that balances capital investment and operating cost. Chengdu Lvsui Technology Co., Ltd. can provide customers with jet aerator selection and layout design services to achieve an optimized configuration of investment and operating costs, thereby reducing the overall cost of wastewater treatment. In the specific selection process, we mainly consider the following factors: 1. Working Pressure of the Jet Aerator The greater the water flow rate, the higher the working pressure of the jet aerator, and the more air it can entrain. Under a specific oxygen transfer requirement, fewer jet aerators may be needed, which lowers equipment procurement cost. However, because higher pressure requires greater pump power and reduces power efficiency, the operating cost will increase. 2. Operating Water Depth Jet aerators are suitable for any water depth. As the water depth increases, both oxygen transfer efficiency and power efficiency improve, and hydraulic power can be reduced, resulting in lower operating costs, as shown in Figure 2. However, greater water depth will also increase civil construction costs. 3. Number of Jet Aerators Increasing the number of jet aerators can reduce the required supporting power. Although the initial investment will rise, the operating cost will decrease. 4. Suction Pressure and Altitude The air intake capacity of a jet aerator is determined under the condition of one atmosphere. When the suction pressure is lower than one atmosphere, it should be corrected by the factor: Correction factor = vacuum pressure / 1 atmosphere When the suction pressure is higher than one atmosphere, it should be corrected by the factor: Correction factor = (gauge pressure + 1 atmosphere) / 1 atmosphere 5. Gas-Liquid Ratio The higher the gas-liquid ratio, the more gas is entrained per unit volume of water. This improves power efficiency but reduces oxygen transfer efficiency. When the gas-liquid ratio reaches 60% to 80%, however, the increase in power efficiency becomes gradual. The reason is that smaller bubble diameter and better bubble distribution in water are generally achieved at lower gas-liquid ratios. Therefore, in pure oxygen aeration, it is not recommended to pursue higher gas-liquid ratios solely for better power efficiency. Instead, an optimal balance point should be identified to consider both oxygen utilization efficiency and oxygen transfer power consumption. In addition to the factors above, water temperature, salinity, operating dissolved oxygen concentration, and the chemical properties of the water will also have important effects on the selection of jet aerator model, quantity, and supporting power.

Product Venturi Injector Jet Pump Jet Compressor Liquid Jet Vacuum Ejector Steam Jet Vacuum System Venturi Scrubber Packed Tower Jet Scrubber Jet Mixing Nozzle Jet Compressor In many fields such as energy, chemical industry, environmental protection, mining, etc., there is a demand for transportation and compression of specific gases. Ejectors for gas transportation and compression can be divided into two types according to the power fluids: gas-powered ejectors and liquid-powered ejectors. Gas-powered ejectors use high-pressure gas as power to pump low-pressure gas, mix it into medium-pressure gas, then discharge it to the downstream process. Its typical applications include high-pressure steam recovery of exhaust steam, low-pressure natural gas recovery, etc. Liquid-powered ejectors use high-pressure liquid as power to transport/compress low-pressure gas to its downstream process.

Priming of centrifugal pump with LJG eductor is one of the various uses.The volume being primed are generally small, so a small quantity of fluid(pressurized water/air)can be applied as motive flow of the eductor GW LJG eductor is also a safe option where it is dangerous to use power driven exhaust. Maintaining Pressure Some apparatus need to keep their internal pressure within a certain extend during operation. meanwhile, there is gas produced or entrained during the process. in this case, GW LJG can be utilized to exhaust gas and keep the pressure at the expected value, The above figure shows an example which is a MBR apparatus for wastewater treatment: When pressure rises in the gas-water separator, a differential pressure signal is given to a motive flow valve which automatically opens and the LJG eductor is activated to draw gas from the separator until the pressure drops to the minus desired point.This configuration not only saves space and investment but also energy since the driving fluid sources(pressure air/water)are always available on-site. --- ### Jet Mixing Nozzle | Mixing Equipment - URL: https://cd-greenwater.com/english/hydraulic-agitation-mixing-nozzle.html - Canonical: https://cd-greenwater.com/english/hydraulic-agitation-mixing-nozzle.html - Language: en - Source: english/hydraulic-agitation-mixing-nozzle.html - Description: Jet Mixing Nozzle Features no moving parts, easy installation and maintenance, suitable for water treatment, exhaust gas treatment, liquid-solid mixing.

So it is highly recommended that injectors be always used in match with nozzles in aeration and ozone dosing application. Jet Mixing Nozzle can be used separately for solo agitating purpose such as anaerobic agitation etc. Number ous cases have proved it as a high reliable and maintenance free device in wastewater treatment industry. Performance Data Function of Jet Mixing Nozzle: 1. To proceed further matter transfer driven by the concentration difference between mixture from the injector and water in ponds/tanks. 2.

Enhancement Nozzles Analysis I. Overview of Enhancement Nozzles Enhancing nozzles are key functional components in jet aeration and fluid mixing systems. Their function is not simply to eject fluid, but rather to further enhance the mixed flow after the initial gas-liquid mixing by the front-end jet injector, thereby improving the system's circulation capacity, mixing efficiency, and mass transfer efficiency. In typical applications, the Venturi jet injector is responsible for creating negative pressure to draw in air, oxygen, or other media and completing the initial mixing; the enhancing nozzle then releases the mixed flow into the pool, container, or pipe in an optimized jet pattern, drawing in more surrounding liquid through diversion, entrainment, and turbulence enhancement. Because of its "secondary enhancement" role at the system's downstream end, the enhancing nozzle becomes a crucial component for improving overall operating efficiency. II. Working Principle of Enhanced Nozzle The working principle of the enhancement nozzle can be summarized as "primary mixing and secondary enhancement". In the first stage, the mixing is completed by the front-end Venturi jet. After the motive water enters the jet, it forms a high-speed fluid in the jet chamber. As the flow velocity increases and the static pressure decreases, air, oxygen or other sucked-in media enter the main fluid and complete the primary gas-liquid mixing inside the jet. In the second stage, secondary intensification is achieved by the enhancement nozzle. After primary mixing, the fluid is injected into the main liquid environment through the enhancement nozzle, where the nozzle structure and jet flow pattern create a stronger entrainment and diversion effect. According to existing local data, the enhancement nozzle can attract approximately 4 to 5 times the amount of surrounding liquid as the working fluid to participate in the mixing, thereby forming a larger-scale circulating flow field and a higher-intensity secondary mixing process. From a fluid mechanism perspective, this process is consistent with the Venturi effect, Bernoulli's principle, and jet entrainment effect. After the fluid accelerates in the contraction section, a low-pressure zone is formed, which in turn draws surrounding fluid into the mixing and diffusion section, achieving flow amplification, enhanced circulation, and improved mass transfer. Therefore, the core value of the efficiency-enhancing nozzle lies not in "ejection," but in "driving more fluid to participate in mixing through jetting." III. Main Advantages of Enhanced Nozzles 1. Improved Oxygen Utilization Efficiency. Enhanced nozzles, through secondary jet intensification, allow the gas-liquid mixture to continue entrainment and turbulence after entering the main liquid phase. This helps expand the contact range between oxygen and water, improving the efficiency of oxygen transitioning from the gas phase to the liquid phase. For wastewater biological treatment systems, this translates to higher oxygen utilization and a more stable oxygen supply. 2. Energy Savings in the System. The efficiency-enhancing nozzles themselves do not directly provide power, but they can make fuller use of existing kinetic water energy by optimizing the jet flow pattern and diversion capacity. Under the same pump power conditions, if the system can achieve a larger circulation range, better mixing effect, and higher oxygen utilization rate, the overall operating energy efficiency will be improved. 3. Expand the area of ​​mixing services. Enhanced nozzles can drive a wider range of liquid flow during spraying, thereby expanding the actual service area of ​​a single unit. For systems that need to maintain sludge suspension, reduce sedimentation, and enhance circulation within the tank, this feature can significantly improve the overall flow field distribution. 4. Improve mixing uniformity. By enhancing secondary mixing and circulation paths, the enhanced nozzles help improve the uniformity of dissolved oxygen distribution, sludge concentration, and overall liquid flow stability within the tank. This advantage is particularly pronounced for aeration tanks, reaction tanks, or container systems where high mixing uniformity is required. 5. Easy to install and requires minimal maintenance. Local data indicates that the N-series enhancement nozzles are characterized by easy installation and maintenance-free operation. As static fluid components, their structure is relatively simple, without complex transmission mechanisms. Provided that the materials and operating conditions are properly matched, they typically have low maintenance requirements and high long-term operational stability. 6. Flexible layout, adaptable to renovation projects. The enhanced nozzles can be flexibly arranged according to the pool type and are suitable for renovation scenarios without interrupting or draining water. This feature has high engineering value for upgrading, expanding, and energy-saving retrofitting existing wastewater treatment facilities. IV. Application Scenarios of Enhanced Performance Nozzles 1. Wastewater treatment aeration system For equalization tanks, homogenization tanks, reaction tanks, and other liquid treatment systems that require strong circulation and anti-deposition capabilities, enhancement nozzles can improve the overall mixing effect by expanding the spray range and strengthening the flow field distribution.... 2. Tanks or containers requiring large-scale circulation and stirring For equalization tanks, homogenization tanks, reaction tanks, and other liquid treatment systems that require strong circulation and anti-deposition capabilities, enhancement nozzles can improve the overall mixing effect by expanding the spray range and strengthening the flow field distribution. 3. Old system efficiency improvement project In existing systems, if there are problems such as insufficient oxygen supply, uneven mixing, weak circulation capacity, or limited modification window, efficiency-enhancing nozzles are suitable as key reinforcement components in efficiency improvement and modification due to their convenient installation and flexible layout. 4. Working conditions requiring high mixing uniformity Enhanced nozzles are also highly applicable in process scenarios requiring improved liquid uniformity, enhanced circulating turbulence, and prevention of localized sedimentation. These needs are not limited to wastewater treatment but are also prevalent in other liquid mixing and circulation applications. Project diagram: V. Engineering Value of Enhanced Nozzles From a system perspective, the efficiency-enhancing nozzle is not simply an end-flow component, but a crucial node that determines whether the mixed flow can fully release energy, form an effective cycle, and achieve efficient mass transfer after entering the main liquid. Its engineering value is mainly reflected in the following aspects: For jet aeration systems, if the front-end jet nozzle solves the problem of "drawing in and initially mixing," then the enhancement nozzle solves the problem of "how to efficiently release and amplify the mixing effect in the main liquid." Only by combining the two can the overall performance of the system be fully realized. VI. Conclusion The enhancement nozzle is a crucial functional component for improving the performance of a jet system. Its core function lies in enhancing oxygen utilization, improving mixing uniformity, expanding the mixing service area, and optimizing the overall system energy efficiency through secondary jet enhancement, entrainment, and circulation amplification. In engineering projects that prioritize aeration efficiency, mixing effect, operating energy consumption, and ease of modification, the enhancement nozzle should not be simply regarded as an ordinary accessory, but rather evaluated and configured as an important component for system performance optimization.

Jet Pump Air Supply Draft tube vortex and air supply requirements When a Francis turbine operates under partial load conditions, vortex bands often appear in the draft tube. This cavity vortex moves periodically in the draft tube, causing strong pressure pulsations and power swings. Adding a certain amount of air to the draft tube is a good measure to destroy the vortex band in the center of the draft tube and eliminate pressure pulsation. Natural air supply and forced air supply According to the operating experience of hydropower stations, when the turbine is installed at a depth of more than 3 to 4 m below the tail water level, natural air replenishment will be difficult due to the increased static pressure on the inner wall of the draft pipe. At this time, forced air replenishment must be performed by equipment such as a jet pump or air compressor. Working principle of air supply jet pump The working liquid of the air supply jet pump is introduced from the high-pressure water in the volute, and a certain amount of free air is sucked in by the nozzle jet; the water and air are mixed into a jet state and supplied to the vortex zone in the draft tube. Factors affecting the air supply effect The air supply effect is related to the suction volume of the jet pump, the outlet pressure of the pump, and the radial distance of the outlet end into the draft tube. When the air intake volume of the jet pump is less than the optimal air supply volume, the pulsating pressure in the draft tube does not decrease but increases. If the outlet pressure of the jet pump is too small, or the distance into the pipe is not enough, air will not be supplied, and sometimes strong noise will occur. In the early stages of operation of the Wujiangdu Hydropower Station, a test was conducted on jet pump air supply, and similar problems were encountered. Design considerations Therefore, when designing an air-supply jet pump, attention should be paid to key parameters such as suction volume, outlet pressure, and extension distance to avoid problems such as insufficient air supply or mismatched parameters that may lead to increased pulsation and noise. Compressed air supply and jet pump series connection solution Compressed air is supplied from behind the water guide vanes of the turbine to the runner area, which has been proven to be an effective air supply method. In the past, it was believed that compressed air consumes a lot and is not widely used; in fact, the amount of air required to eliminate unstable operating conditions of Francis turbines is about 5% of the rated flow rate (m³/s) of the turbine (converted to atmospheric pressure), and the air pressure is 0.5 times the working head of the turbine. If a jet pump is connected in series in a compressed air pipe network, and compressed air is used as the working fluid of the jet pump, allowing it to inhale a certain amount of free air, it will not only improve the air supply effect, but also reduce power consumption by 1/2 to 1/3. Conclusion Jet pump air supply is an effective means to destroy the draft tube vortex and suppress pressure pulsation. In actual projects, the suction volume, outlet pressure and extension distance of the jet pump should be specially designed based on the layout of the water head and draft tube of the power station and the optimal air supply volume requirements. If necessary, a series connection scheme of compressed air and jet pumps can be used to balance the air supply effect and operating economy.

Summary of the Application of Jet Pumps in Hydropower Stations Jet pump is a kind of fluid transport equipment without rotating parts. It has the advantages of simple structure, reliable operation, convenient maintenance and low cost. In recent years, it has been widely used in large and medium-sized hydropower stations at home and abroad, and has received good benefits. Related equipment is also called injection pump, ejector, etc. Definition and characteristics: 1. No rotating parts, simple structure 2. Reliable operation and easy maintenance 3. Low cost, suitable for power station auxiliary system applications 4. Can be driven by using excess power fluid such as high-pressure water in front of the dam or in the volute Application areas: 1. Technical water supply for hydropower station units 2. Removing sediment from water collection wells 3. High-pressure air system, phase-modulated pressurized water, air supply and water level maintenance in series Technical water supply of unit: One of the important applications of jet pumps in hydropower stations is unit technical water supply. Recent research results - needle valve adjustable jet pump, which has the advantages of high efficiency and wide working range, and is suitable for technical water supply systems of hydropower station units with large changes in water head and load. For power stations with small head changes, fixed jet pumps can be used. Draining mud from water collection wells: In the drainage system, it is recommended to use a jet pump to remove sediment from the water collection well. Compared to mud pumps, jet pumps are more efficient and save electrical energy. Series applications in phase-modulated pressurized water: When using a high-pressure air system for phase-modulated water pressure, a jet pump can be connected in series in the high-pressure air system to suck in a certain amount of free air; and a jet pump can be used instead of a blower to maintain the reduced water level in the runner chamber. This can not only obtain the best working parameters for phase-modulated water pressure, but also save investment and greatly simplify the layout of water pressure equipment and air pipe networks. Key points for selection: When selecting a project, a reasonable choice should be made between needle valve-adjustable and fixed jet pumps based on the range of changes in water head and load. In high-pressure gas systems such as phase-modulated water pressure, the comprehensive benefits of the jet pump's series air supply and water level maintenance can be further exploited.

Introduction to the application of jet pumps in sewage discharge from water collection wells in power stations Problems with sewage discharge from deep water collection wells All leaking water and other leaking water in the factory are discharged to the leakage collection well, followed by a large amount of sludge. On rivers with a lot of mud and sand, a large amount of mud and sand will be deposited at the bottom of the maintenance drainage well every time the unit is inspected. For many years, there has been no good way to solve the problem of sewage discharge from deep water collection wells; in the past, manual cleaning was mainly used. The water collection well is tens of meters deep, the working environment is very harsh, and underground operations are very inconvenient and the work efficiency is extremely low. Limitations of mud pump sewage discharge In order to improve working conditions, some power station designs have used mud pumps or ash pumps, which can pump a certain amount of mud to varying degrees, but there are also many problems. First of all, because the centrifugal pump is limited by the suction height, it must be placed at a very low position when used. However, the water collection well has accumulated water for a long time. If the mud pump is installed in the well, it will be submerged by the accumulated water. Therefore, it can only be temporarily placed during mud discharge, and manual flushing is required, which brings trouble to the cleaning work. Secondly, mud pumps sometimes experience mechanical failures due to mud and sand wear. Therefore, even if some power stations are designed with mud pump sewage discharge devices, they sometimes have to use manual cleaning. In view of the above reasons, it is very necessary to research a reliable deep well mud drainage device. Characteristics of jet pump The jet pump has no rotating parts, has a simple structure and works reliably. Easy to install and maintain. Therefore, it is widely used in water conservancy, electric power, chemical industry, water supply and drainage, sewage treatment, heating, ventilation and refrigeration and other departments. Especially in harsh conditions such as high temperature, high pressure, explosive, flammable, humid and deep water, the advantages are more significant. However, the efficiency of the jet pump is low. When used as a vacuum pump, the ultimate vacuum degree is limited by the vaporization pressure of the working liquid. Especially if the operating range is narrow and slightly deviates from the optimal working conditions, the efficiency will be reduced, and sometimes even reverse flow will occur. Product picture: Application conditions of jet pumps in hydropower stations Medium and high head hydropower stations provide reliable working water sources for jet pumps. The compressed air used in phase modulation and braking in power stations can also be used as the pressure air source for liquid-gas jet pumps. Jet pumps are used in various systems in hydropower stations due to their unique advantages. Special advantages of jet mud pump for deep well drainage In addition to the general advantages of jet pumps, using a jet mud pump to operate deep well sewage drainage also has the following special advantages: it can pump solids with larger diameters; it can operate underwater and has great flexibility; it can automatically discharge sewage after configuring a complete mud flushing system, without the need for manual underground operations. Therefore, the use of jet mud pumps for deep well sewage discharge has greatly improved the working conditions of operation and maintenance personnel and better solved the problem of sewage discharge from water collection wells. Engineering application The use of jet pump devices to discharge sewage from water collection wells in the factory has been reported abroad. Jet pump devices are also used to discharge sewage from the water collection wells of Gezhouba Ship Lock in China.

Jet Pumps for Phase-Modulated Water Pressure in Generator Units Phase modulation operation and pressurized water requirements With the development of industry, more and more units are used for phase modulation operation, and some large hydropower stations also need to consider phase modulation operation. In order to make the unit consume less active power during phase adjustment, most power stations use compressed air to press water to dehydrate the runner for phase adjustment operation. Traditional low-pressure gas systems and their limitations In the past, phase-modulated pressurized water used an air system with a pressure of 0.5 to 0.8 MPa. Due to the emergence of large-capacity units or several units performing phase modulation at the same time, the equipment and layout of the gas system have encountered difficulties; if the design is improper, the water pressure often fails. Therefore, in recent years, it has been proposed to use high-pressure gas systems for phase-modulated water pressure, and has been successful in practice. High-pressure gas system phase-modulated water pressure According to reports, high-pressure gas systems with a pressure of 4 MPa or 6.3 MPa are used abroad to perform phase-modulated water pressure. The purpose of using such a high air pressure is to solve the problem of air system equipment and to share the high-pressure air compressor of the speed control system without the need for additional equipment. When the high-pressure air successfully presses water for the first time, use a blower to keep the water level in the runner chamber from rising. Optimal air pressure and risk of air-water hammer According to the high-pressure phase-modulated water pressure test data, the optimal pressure of phase-modulated water pressure is about 2.5 MPa. When the pressure exceeds 2.5 MPa, not only the actual water pressing time cannot be reduced, but on the contrary, air-water hammer is easily generated. High-pressure system equipment utilization At present, the pressure used in the speed control system of large hydropower stations is 4 to 6 MPa or even higher, while the pressure of air compressors is 6 MPa or 15 MPa. In order to give full play to the role of compressed air equipment in high-pressure systems while achieving safety and economical purposes, it is necessary to optimize the phase-modulated water pressure method. Jet pump series high-pressure gas system solution At the Second National Academic Symposium on Jet Technology in 1986, it was recommended to install a jet pump on the high-pressure air system pipeline. The high-pressure air should be used as the working pressure of the jet pump, so that the jet pump absorbs a certain amount of free air. After the two are mixed, they are sent to the runner chamber for phase modulation and first water pressure. When the water pressure is successful, a low-pressure jet pump (outlet pressure is 0.5 to 0.8 MPa) is used to maintain the depressed water level in the runner chamber, replacing the large blower. This not only saves electric energy and obtains the best parameters for phase-modulated water pressure in the high-pressure gas system, but also greatly simplifies the layout of auxiliary equipment and reduces equipment costs. Conclusion Using a jet pump in series with a high-pressure air system for phase-modulated water pressure has the potential to simplify equipment layout and reduce investment and operating energy consumption. Of course, using such a phase-modulated water pressure solution still requires a lot of model testing in order to obtain the best combination of the jet pump structure type and water pressure working parameters.

Product Venturi Injector Jet Pump Jet Compressor Liquid Jet Vacuum Ejector Steam Jet Vacuum System Venturi Scrubber Packed Tower Jet Scrubber Jet Mixing Nozzle Jet Scrubber Jet scrubber is a special ejector for the purpose of washing gas with liquid. The jet scrubber uses a nozzle with a special structure to spray the pressurized liquid (washing liquid) into high-speed flowing conical mist droplets. After the liquid is sprayed into droplets, the specific surface area increases, and the surrounding gas is driven to move with it by viscosity, thereby generating suction force to inhale the washed gas. After being inhaled by the washed gas, the particles in the gas are captured by the droplets due to collision with the droplets, and the gas soluble in the washing liquid in the gas is also transferred into the droplets. Finally, the droplets and gas mixture are separated by the separator, and the gas is discharged at the same time, realizing the entire gas washing process. The jet system has a simple structure, stable operation, and does not require a fan. It can be used for cooling and dust removal of flammable and explosive, high-temperature, high-humidity, and high-dust gases. The size of the standard scrubber can meet the processing capacity requirements from a few cubic meters per hour to thousands of cubic meters.

Design elements of jet injectors for ozone dosing The required ozone quantity and dosage are determined by the customer based on test data for specific projects and the ozone gas concentration specified by the ozone manufacturer. This article addresses the design considerations for ozone mass transfer under conditions of guaranteed ozone supply quantity, concentration, and supply pressure. 1. Ozone transfer efficiency ηo3 ηo3 = Ozone demand / Ozone supply Ozone mass transfer is affected by a series of factors, including water depth, air-to-water ratio, residence time, water quality, pH, water temperature, water pressure, and ozone concentration. Water quality, pH, and water temperature are determined by the customer's specific circumstances. This guide discusses the selection and efficiency optimization of water depth, air-to-water ratio, and residence time. 2. Water depth The impact of water depth on ozone transfer efficiency is obvious. The deeper the water, the higher the ozone transfer efficiency, and vice versa. However, deeper water means greater infrastructure investment. 3. Air-to-water ratio The gas-to-water ratio refers to the ratio of the amount of ozone oxygen drawn into the jet injector to the amount of motive water. Under conditions of constant water depth and jet injector inlet working pressure, a smaller gas-to-water ratio results in higher ozone transfer efficiency. With a fixed air supply, more ozone is actually transferred into the water. This means that a smaller ozone generator and less oxygen supply can be used. However, a smaller gas-to-water ratio, with a fixed air supply, requires a larger circulating water volume, necessitating a larger pump and higher power output for the jet injector. 4. Import pressure With a fixed water depth and air-to-water ratio, the higher the working pressure at the jet injector inlet, the higher the ozone transfer efficiency, and the higher the corresponding power of the jet injector circulating water pump. 5. Summarize Therefore, when designing and selecting equipment, it is necessary to comprehensively balance the water depth, gas-water ratio, inlet and outlet working pressure, and overall operating costs while ensuring the ozone dosing effect, so as to control the operating costs to the minimum.

Product Venturi Injector Jet Pump Jet Compressor Liquid Jet Vacuum Ejector Steam Jet Vacuum System Venturi Scrubber Packed Tower Jet Scrubber Jet Mixing Nozzle Packed Tower A packed tower is a widely used high-efficiency gas-liquid mass transfer equipment with the characteristics of low pressure-drop, low energy consumption and high efficiency. It is widely used in chemical separation processes such as distillation, gas absorption and cooling. It’s usually used for the treatment of clean and particle-free gas. The liquid enters from the upper part of the tower, is evenly distributed on the packing through the liquid distributor, and then flows downward along the surface of the packings to transfer heat and mass with the ascending gas. The gas enters from the lower part of the tower, passes through the gas distribution device, and evenly passes through the packing layer upward, and contacts the spray liquid on the surface of the packing. The packed tower is a continuous contact gas-liquid mass transfer equipment. Usually, the gas phase is a continuous phase, and the liquid phase is a dispersed phase. The composition of the gas phase and the liquid phase changes continuously along the height of the packing layer until the ideal gas phase composition is obtained at the top of the packing layer. Performance Data Basic structure diagram The packed tower is divided into four sections from bottom to top: the tower bottom section, the gas inlet section, the mass transfer section, and the mist removal section at the tower top. The section between the tower bottom and the mass transfer packing layer constitutes the gas inlet section. The structural design of the gas inlet section aims to ensure uniform distribution of the treated gas while minimizing gas pressure drop. The mass transfer section is the most critical part of a packed tower. All structural internals within the mass transfer section must not only meet strength requirements but also ensure uniform distribution and flow of gas and liquid. The largest possible free flow area must be maintained while also meeting the requirements for installation, removal, and maintenance of the tower structure and packing. The packing mass transfer section constitutes the top portion of the tower, primarily serving to remove mist droplets. Demisters are available in various types and materials. --- ### Principle Analysis · Case Studies · Equipment Selection - URL: https://cd-greenwater.com/english/article.html - Canonical: https://cd-greenwater.com/english/article.html - Language: en - Source: english/article.html - Description: This Page offers systematic professional solutions for wastewater treatment, exhaust gas treatment, vacuum conveying, and related fields.

Aeration must deliver oxygenation ≥ oxygen demand. Aeration: Principles, Essence and Purpose The principle of aeration The transfer of oxygen from the air to the water is a gas-liquid two-phase mass transfer process. The mechanism of this process is generally explained by the double-membrane theory. By understanding the principle of double membrane theory, we know that to improve the mass transfer of oxygen in the air in the water body, we must: 1. Reduce the size of the bubbles. The smaller the bubbles, the greater the specific surface area of gas-liquid contact. 2. Increase the gas-liquid contact time. 3. Increase the stirring intensity. The stronger the mixing, the more severe the turbulence and the greater the gas transfer rate. Simplified diagram of the two-mode theory of gas transfer: The nature and purpose of aeration In the sewage treatment process, the purpose of aeration is to: 1. Provide oxygen for the oxidative decomposition of organic matter (process object). 2. Create an aerobic environment for the survival and reproduction of aerobic microorganisms. 3. Make full contact with organic matter, microorganisms and oxygen. Therefore, the essence of the work of the aeration equipment is to transfer the oxygen in the air to the water with efficient oxygenation amount ≥ oxygen demand, thereby achieving: oxygenation amount ≥ oxygen demand.

Steam Ejector (Gas Jet Vacuum Unit) Product overview Steam ejector is the core component and commonly used name for steam jet vacuum units and gas jet vacuum units in industrial sites. A single steam ejector can be used independently; a multi-stage steam ejector combined with a condenser forms a complete steam jet vacuum unit. The "steam ejectors" in this article refer to gas jet vacuum units and other related products provided by Chengdu Chengdu GreenWater. How steam ejectors work Like other ejectors, steam ejectors are also jet devices that work based on the Venturi effect. It is the core product of the vacuum solution of Chengdu Chengdu GreenWater Co., Ltd. It can be used alone or can be connected in multiple stages to form a steam jet vacuum unit to provide stable vacuum for distillation, drying, filtration, degassing and other processes. During operation, motive steam passes through the expansion nozzle, converting pressure energy into kinetic energy and creating a vacuum, thereby injecting a mixture of air, process gas and steam into the Venturi diffuser. After momentum exchange, the kinetic energy of the motive steam is converted into the pressure energy of the mixed medium, and is discharged after reaching the predetermined back pressure. Working process:The steam converts pressure energy into velocity kinetic energy through the expansion nozzle, creates a vacuum, mixes the inhaled fluid, and then slows down the speed in the diffusion section and the pressure rises to overcome the outlet back pressure before being discharged. Product picture Basic structure of steam ejector The steam ejector is the core unit of the steam jet vacuum unit (gas jet vacuum unit). Each steam ejector itself is a complete Venturi jet equipment, consisting of the following four key components: Component Function Expansion nozzle Motive steam enters and accelerates, converting pressure energy into kinetic energy, which is the source of energy to create vacuum Suction chamber The nozzle outlet forms a low-pressure zone that injects air, process gas or steam Mixing chamber The motive steam mixes with the ejected medium, and momentum exchange occurs Diffusion section The flow channel gradually expands, the mixed fluid decelerates and increases pressure, and is discharged after overcoming the outlet back pressure Single unit and multi-stage configuration 1. Single unit: independently responsible for vacuuming, suitable for small occasions with low vacuum requirements.2. Multi-stage series connection (condensing type): Multiple ejectors pump air step by step, and the intermediate condenser reduces the load of the next stage. 3. Multi-stage series connection (non-condensing type): direct series connection, suitable for small and low-consumption working conditions. Material selection Steam ejectors can be made of a variety of materials according to working conditions: Material type Typical materials Applicable occasions Metal material Stainless steel, Monel, Hastelloy, titanium, bronze High temperature, corrosive media Non-metallic material Graphite, polytetrafluoroethylene (PTFE) Strong corrosion, special media Application areas of steam ejectors In addition to being used as vacuum pumps, steam ejectors have been widely used in industrial processes due to their characteristics of generating vacuum, ejection mixing, and boosted discharge: Industry Typical uses Petrochemical industry Crude oil vacuum distillation unit (VDU) pressure reduction system, vacuum distillation Chemical industry Reactor degassing, solvent recovery, vacuum drying Electric power Condenser vacuuming, geothermal power generation Food/Pharmaceutical Vacuum distillation, concentration, drying Metallurgy Vacuum degassing, VD/VOD auxiliary vacuum FAQ What is the difference between a steam ejector and a steam jet vacuum unit? The steam ejector is a single jet vacuum equipment; the steam jet vacuum unit is a complete vacuum system composed of multiple steam ejectors and intermediate condensers connected in series. In engineering applications, "steam ejector" often refers to the entire unit system. What is the relationship between steam ejector and gas jet vacuum unit? Gas jet vacuum unit is a jet vacuum system that uses steam or other gases as the power medium. When steam is used as power, it is a steam jet vacuum unit, and the core equipment is a steam ejector. How to choose condensing or non-condensing type? For small units and situations with low power consumption, fewer stages can be considered, and even a condenser (non-condensing type) is not required. For high vacuum and large flow conditions, it is recommended to use a multi-stage condensing unit to reduce steam consumption and reduce equipment size.

Multi-stage, no moving parts. What is a steam ejector? 1. Introduction In modern industrial processing, creating and maintaining a reliable vacuum environment is essential for optimizing product quality, reducing energy expenditure, and facilitating complex chemical reactions. A Steam Ejector — often referred to as a steam jet vacuum pump or steam jet ejector—is a highly specialized piece of stationary equipment designed to produce a vacuum, compress gases, or transport process fluids. Unlike conventional mechanical vacuum pumps that rely on pistons, impellers, or rotating screws, a steam ejector uses a high-velocity steam jet to entrain and compress gases. For industrial clients, this means a system entirely devoid of internal moving parts. It serves as an ultra-reliable, heavy-duty alternative to mechanical equipment, particularly in harsh processing environments where dust, corrosive vapors, or high-temperature gases would rapidly destroy traditional machinery. Whether used as a single unit or arranged in complex multi-stage configurations, the steam ejector remains a cornerstone of robust process engineering worldwide. 2. Working Principle The engineering architecture of a steam ejector depends on fundamental principles of thermodynamics and fluid mechanics—specifically the Venturi effect and gas dynamics. The entire operation can be broken down into three distinct, continuous phases that happen within the internal geometry of the device. Phase 1: Expansion and Acceleration (The Nozzle Section) The process begins when high-pressure motive fluid (typically superheated or dry saturated steam) enters the ejector's chest. It is directed through a precisely machined convergent-divergent nozzle (also known as a de Laval nozzle). As the steam passes through the restricting throat of the nozzle, its static pressure energy decreases while its velocity increases. Upon exiting the divergent portion of the nozzle into the suction chamber, the steam expands completely, accelerating to supersonic velocities—typically between Mach 2 and Mach 5. Phase 2: Entrainment and Momentum Transfer (The Suction & Mixing Chamber) This drastic acceleration of the steam jet results in a localized, extremely low static pressure zone within the suction chamber. Because the pressure in this chamber is significantly lower than the pressure of the connected process vessel, the process gas, vapor, or air is naturally drawn into the ejector body. Once inside, the process gas meets the supersonic steam jet. In the mixing section, a high-velocity momentum transfer occurs: the fast-moving steam entrains the slower process molecules, creating a uniform, homogeneous mixture of steam and process gas. Phase 3: Compression and Deceleration (The Diffuser Section) The mixed fluid then passes into the diffuser, which features a convergent inlet, a narrow throat, and a divergent outlet. As the mixture flows through the expanding divergent profile of the diffuser, its velocity is deliberately forced to decrease. According to Bernoulli's principle and the conservation of energy, this deceleration forces the kinetic energy of the supersonic stream to convert back into static pressure energy. Consequently, the mixture is compressed to a discharge pressure that is significantly higher than the suction chamber pressure, allowing it to be discharged into a condenser, a subsequent ejector stage, or directly into the atmosphere. 3. Key Advantages of Steam Ejectors When comparing vacuum technologies, engineering teams frequently select steam ejectors over liquid ring pumps, dry screw pumps, or rotary vane systems due to a distinct set of operational and economic advantages. • Zero Internal Moving Parts : Because the device relies entirely on fluid dynamics rather than mechanical motion, there are no bearings, gears, pistons, or seals to lubricate, wear out, or replace. This translates directly into unprecedented mechanical reliability and exceptionally long intervals between overhauls. • High Tolerance for Hostile Process Fluids : Mechanical pumps struggle with carryover. A steam ejector easily handles wet steam mixtures, corrosive chemical gases, abrasive particulate matter, and explosive vapors without risking catastrophic mechanical failure. • Low Capital Investment & Economical Scaling : The initial capital cost of a steam ejector is significantly lower than that of a mechanical pump of equivalent volumetric capacity. For massive volumetric flow rates under deep vacuum conditions, steam ejectors offer the lowest capital-expenditure-to-performance ratio on the market. • Explosion-Proof and Safe Operation : Since they operate without electrical connections or friction-generating components within the process stream, steam ejectors are inherently safe for hazardous environments (such as ATEX Zone 0 or Zone 1 zones) without requiring expensive explosion-proof enclosures. • Flexible and Compact Installation : Ejectors feature a relatively lightweight, compact footprint. They can be mounted horizontally, vertically, or obliquely, and are frequently suspended directly from piping systems, minimizing structural support costs and saving valuable floor space. 4. Primary Application Areas Steam ejectors are highly versatile units utilized across a wide variety of global industries: Oil Refining and Petrochemicals In petroleum refining, the Crude Oil Vacuum Distillation Unit (VDU) is perhaps the most prominent application. To separate heavy hydrocarbons without causing thermal cracking, heavy atmospheric residues must be distilled at pressures as low as 10 to 30 mbar. Multi-stage steam ejector systems, coupled with inter-condensers, are uniquely qualified to manage these heavy, corrosive, and high-temperature hydrocarbon loads continuously. Power Generation In thermal, nuclear, and combined-cycle power plants, steam turbines exhaust into a surface condenser to optimize thermal efficiency. Maintaining a deep vacuum inside this condenser is vital. Steam ejectors are deployed as hogging and holding systems: during startup (hogging), they quickly evacuate air from the condenser; during normal operation (holding), they continuously remove non-condensable gases that leak into the system, preserving peak turbine performance. Chemical and Pharmaceutical Processing Many chemical syntheses, polymerizations, and pharmaceutical ingredient extractions require gentle, low-temperature boiling or drying to prevent product degradation. Steam ejectors provide the stable vacuum necessary for industrial evaporators, crystallization vessels, vacuum dryers, and deodorization plants (common in edible oil processing). Metallurgical Industry In modern steelmaking, technologies like Vacuum Degassing (VD) and Vacuum Oxygen Decarburization (VOD) are used to produce high-purity, low-carbon steels. These processes release massive volumes of hot, dusty carbon monoxide and hydrogen gases. Steam ejectors easily tolerate these harsh, dusty gas streams, evacuating massive metallurgical ladles in minutes. 5. Industrial Case Studies Case Study 1: Eliminating Downtime in an Oil Refinery VDU • Background: A mid-sized refinery in North America was operating a Vacuum Distillation Unit utilizing a mechanical dry-screw vacuum pump system. The process gas carried over highly corrosive sulfur compounds and abrasive catalyst fines, resulting in rotor binding and pump failures every 4 to 6 months. Each failure caused millions of dollars in lost production and specialized maintenance fees. • Solution: The refinery replaced the mechanical system with a custom-engineered 3-Stage Steam Ejector System with Shell-and-Tube Inter-condensers • Results: The steam ejector system successfully accommodated the corrosive compounds and catalyst fines without any loss in performance. The refinery reported zero unscheduled downtime related to the vacuum system over a consecutive 4-year period, resulting in an estimated saving of over $3.2 million in maintenance and lost-revenue costs. Furthermore, the refinery utilized existing waste steam from a neighboring boiler unit as the motive fluid, making the system highly energy-efficient. Case Study 2: Restoring Efficiency in a 500MW Thermal Power Plant • Background: A coal-fired power station was experiencing sub-optimal generating efficiency due to an aging, deteriorating liquid ring vacuum pump system used for condenser air-holding. The system could no longer maintain the design vacuum of 40 mbar, causing turbine backpressure to rise and reducing the facility's net megawatt output. • Solution: Engineers retrofitted the plant with a modern, twin-element 2-Stage Steam Ejector Air Extraction Package. The twin-element configuration offered 2x100% redundancy, allowing maintenance or inspection on one leg without taking the power plant offline. • Results: Immediately upon commissioning, the new ejectors restored the condenser vacuum to its optimal design parameters. The corrected turbine backpressure led to a 0.8% increase in overall plant generation efficiency, translating into substantial annual fuel savings and a full return on investment (ROI) within less than 9 months of operation. 6. Summary & Industry Targeting The steam ejector represents a masterful application of fluid dynamics that solves some of the toughest vacuum-generation challenges in modern engineering. By leveraging high-pressure motive steam to compress and move gases without a single moving component, it achieves operational uptime and reliability that mechanical alternatives simply cannot match. While steam ejectors can be deployed in almost any facility with an active boiler system, specific industrial sectors depend on them as mission-critical infrastructure: • Refineries & Petrochemical Complexes: Essential for continuous vacuum distillation units where equipment failure stops the entire production line. • Power Plants: Required to continuously purge non-condensable gases from large-scale surface condensers to keep electricity generation efficient. • Heavy Metallurgy: Vital for high-volume ladle degassing where hot, abrasive, dust-laden gases would quickly degrade mechanical components. For operations looking to maximize process uptime, lower maintenance overhead, and establish a rugged vacuum infrastructure capable of handling hostile process streams, the steam ejector remains the premier, time-tested choice.

Technical Water Supply Jet Pump for Hydropower Units Working principle and efficiency The jet pump for technical water supply of the unit uses the high-pressure water from the volute or the reservoir in front of the dam as working water, absorbs the river water downstream of the power station, and uses all the water flow passing through the jet pump for the technical water supply of the unit. Since both working water and sucked water are effectively utilized, the maximum efficiency of the water supply jet pump can reach 62% to 65%. Jet pump efficiency is closely related to area ratio. Usually, the efficiency is higher when the area ratio is smaller; when the area ratio is 4 to 5, the work efficiency can generally reach 45% to 55%. Water supply safety and scope of application The outstanding advantage of using a jet pump for water supply is that the cooling water of the unit is not easily interrupted, thus ensuring the safe operation of the unit. In the technical water supply system of large and medium-sized hydropower station units with a water head section of 80 to 150 m, using jet pumps instead of conventional water pumps or gravity-reduced water supply not only has significant energy saving effects, but also operates safely and reliably. Noise control under high water head conditions When jet pumps are used in hydropower station technical water supply systems with water heads above 200 m, the operating noise is usually high. Model tests show that when the working head of the jet pump nozzle inlet is 200-250 m, the measured noise is about 101-104 dB. Therefore, when high-head power stations use jet pumps to supply water, sound insulation measures should be taken to meet ergonomic requirements. Model tests also show that covering the jet pump with about 20 cm of sand can reduce operating noise by about 10 dB, providing a reference technical solution for engineering sound insulation design. Fixed jet pump series test According to the requirements of the project "Application of Jet Pumps in Large and Medium-sized Hydropower Stations with Medium and High Heads", a series of model tests of fixed jet pumps for technical water supply of units in the 70-110 m water head section have been completed. The test area ratio ranges from 2.5 to 7.0, with one level set every 0.5. A total of 10 sets of area ratio tests have been completed, which can provide designers with corresponding pressure-flow performance curves. On this basis, a product series of fixed jet pumps with a water head section of 70 to 150 m can be further compiled to provide a basis for the design and selection of the technical water supply system of hydropower station units. Effect of water head changes on fixed jet pump The working conditions of jet pumps in the technical water supply system of hydropower station units are significantly different from those in other industrial applications. Due to the constant changes in water levels upstream and downstream of the power station, the fixed working conditions of the jet pump will be broken, and its flow rate and pressure will also change significantly. When the actual water head deviates from the design working condition of the jet pump by about 30 to 50 m, the equipment may experience insufficient water supply or severe cavitation noise. For power stations with a large range of water head changes, it is difficult for fixed-nozzle jet pumps to cover all operating conditions; if they rely on frequent replacement of nozzles to maintain stable operation, it will increase the inconvenience of maintenance and repair. Needle valve regulated jet pump In order to adapt to changes in water head and load, a movable needle valve can be installed in the jet pump nozzle. By adjusting the needle valve position to change the effective area ratio, the jet pump can adapt to changes in the power station's operating water head and unit load, thereby maintaining stable water supply and achieving energy-saving operation under changing operating conditions. The Northwest Survey and Design Institute of the Ministry of Water and Power and Wuhan Institute of Hydropower have collaborated to conduct a large number of model tests on needle valve-regulated jet pumps, and have achieved a structural type with good performance and low noise. The needle valve-regulated jet pump has the characteristics of wide working range and high efficiency, and is suitable for the technical water supply system of hydropower station units with large changes in water head and load. In addition to improved performance parameters, its operating noise can also be about 5 to 10 dB lower than similar foreign equipment. Technology development direction The model test work of the needle valve regulated jet pump has been initially completed. In the future, it is still necessary to accumulate experience through the actual operation of the power station, continue to improve the design quality, and further study the formation and control methods of operating noise to reduce the equipment noise to the allowable sound level range. Conclusion Unit technical water supply jet pumps have the advantages of energy saving, safety and reliability. Fixed jet pumps are suitable for working conditions with small changes in water head; for power stations with large fluctuations in water head and load, needle valve-regulated jet pumps can provide a wider working range and more stable water supply performance. In actual projects, special design and selection should be carried out based on the water head range, water supply flow rate, pressure requirements and noise control objectives.

Venturi Nozzle (Hydraulic Mixing Nozzle) Venturi nozzle is a common name for hydraulic mixing nozzles and mass transfer diffusion nozzles in industrial and water treatment projects. The three refer to the same type of fluid power equipment that uses liquid jets to achieve stirring and mixing. The "Venturi nozzles" in this article all refer to the hydraulic mixing/mass transfer diffusion nozzle products provided by Chengdu Chengdu GreenWater. Venturi nozzle (hydraulic mixing nozzle) is a fluid mixing device that uses pressure liquid as power. The pressure energy of the high-pressure liquid is converted into kinetic energy at the nozzle and sprayed at high speed. The high-speed jet drives the liquid around the nozzle that is equivalent to 3 to 5 times the flow rate of the sprayed liquid to flow together, and finally achieves uniform mixing in the pool. Product picture Principle of hydraulic mixing The hydraulic mixing of the Venturi nozzle is based on the principles of jet entrainment and momentum transfer, and is in the same vein as the Venturi effect - utilizing the velocity changes in the contraction-expansion flow channel to achieve energy conversion and fluid ejection. Mixing process: 1. The high-pressure liquid is pumped into the Venturi nozzle, and the pressure energy at the nozzle is converted into high-speed kinetic energy. 2. The high-speed jet is ejected from the nozzle and entrains the surrounding liquid, driving 3 to 5 times the flow rate of the liquid in the pool to move together. 3. Momentum exchange occurs between the jet and the surrounding liquid, forming a large-scale circulating flow field. 4. The circulating flow field fully mixes the liquid (or liquid-solid mixture) in the pool to achieve uniform mixing. Venturi nozzles have no moving parts, simple structure, and stable operation. They can be designed according to the mixing speed/energy consumption requirements of different projects, and can be well adapted to the mixing needs of liquids (liquid-solid mixtures) of various sizes and any liquid level depth. Dual action of Venturi nozzle After the hydraulic mixing nozzle is used in the Venturi injector, the remaining pressure at the injector outlet is used for injection, which can simultaneously achieve hydraulic mixing and enhanced gas-liquid mass transfer: 1. Secondary mass transfer The concentration difference between the mixed liquid at the ejector outlet and the liquid in the pool is used to perform secondary mass transfer to improve the gas-liquid two-phase mass transfer efficiency. 2. Hydraulic mixing The remaining pressure head is used to complete the process of mixing the liquid in the pool evenly without additional power. Core advantages No mechanical rotating parts It is driven by pure fluid power and has no wearing parts such as bearings and seals, so the failure rate is extremely low. No scaling or cloggingThe flow channel is smooth, almost no daily maintenance is required, and the maintenance cost is extremely low. Flexible layout and installationIt can be flexibly arranged according to the pool type and liquid level depth to adapt to pools of various sizes. Adapt to special working conditionsIt is suitable for situations where it is difficult for traditional mechanical agitators to operate stably, such as corrosive environments, radiation hazards, and deep liquid levels.

In engineering applications, Venturi nozzles usually refer to hydraulic mixing nozzles. Because its nozzle structure is based on the Venturi effect and uses jet entrainment to achieve mixing, it is called a Venturi nozzle. How does a Venturi nozzle achieve hydraulic mixing? The high-pressure liquid accelerates through the nozzle to form a high-speed jet, entraining 3 to 5 times the flow rate of liquid around it to flow together, forming a circulating flow field in the pool through momentum exchange, and achieving uniform mixing without mechanical parts. What are the advantages of a Venturi nozzle over a mechanical stirrer? It has no moving parts, no scaling and clogging, extremely low maintenance costs, and flexible layout. It is especially suitable for situations with corrosive or radiation hazards or deep liquid levels. It is an irreplaceable choice for traditional mechanical agitators.

Packed Tower Packed tower is a commonly used mass and heat transfer equipment in chemical industry, which is widely used in the fields of oil refining, petrochemical industry, fine chemical industry, chemical fertilizer, pharmaceutical industry, environmental protection, etc. It is the preferred equipment for most of the processes such as cooling, absorption, distillation, purification, separation, desorption, gas extraction, extraction, chemical exchange, washing, and so on. Cyclone Washing Tower: Cyclone scrubber tower is a kind of packing tower equipment developed by our company which combines separator and scrubber tower into one, and is suitable for the process with less solid particles content. Compared with two separate tower equipment, cyclone scrubber tower occupies less space and has smaller investment. Jet Scrubber The use of wet scrubbers to control air pollution has been widely recognized throughout the industry. Injector-Venturi wet scrubbers offer many advantages over many traditional single-purpose units. Particle collectors such as cyclones and electrostatic precipitators do not effectively absorb gases or remove odors. Fabric filters are not designed to handle gas streams with high moisture content and are often subject to highly corrosive gases. Catalytic incinerators can be rapidly poisoned by certain organic wastes. On the other hand, the Injector-Venturi Gas Scrubber is very effective in removing harmful gases, particles, odors, smoke and ash from the air stream. Particulate contaminants are removed by the high velocity spray impact of the scrubbing fluid. Gases and odors are removed by absorption and/or chemical reaction between the gas and the scrubbing solution. When properly matched to the application, these scrubbers are by their very nature better able to cope with the high temperatures and corrosive conditions often encountered.

Working Principles and Applications - Chengdu GreenWater - URL: https://cd-greenwater.com/english/Jet-Pump-detail.html - Canonical: https://cd-greenwater.com/english/Jet-Pump-detail.html - Language: en - Source: english/Jet-Pump-detail.html - Description: What is a jet pump? Guide covering working principle, components (nozzle, throat, diffuser), types, applications, advantages, and selection criteria. What Is a Jet Pump? How Does a Jet Pump Work? A jet pump, also known as an eductor, ejector, or injector, is a device that uses a pressurized motive fluid to entrain and transport a lower-pressure suction fluid. The motive fluid passes through a nozzle, accelerating and reducing its static pressure, creating a low-pressure zone in the suction chamber. The suction fluid then enters the device and mixes with the motive fluid in the throat, exchanging momentum. The mixed flow finally enters the diffuser section, where velocity decreases and part of the kinetic energy is converted back to pressure energy before discharge. Industrial jet pumps typically have no impellers, motors, or other moving parts in the body. They require an external pump, compressor, or high-pressure process fluid to provide motive power, making them particularly suitable for gas-liquid mixing, liquid-liquid mixing, aeration, chemical dosing, vacuum generation, and hard-to-maintain operating conditions. I. What Is a Jet Pump? A jet pump is a fluid device that relies on momentum transfer from a fluid jet to achieve suction, mixing, pressurization, or transport. Unlike a centrifugal pump, which continuously imparts work to a liquid through a rotating impeller, a jet pump converts the existing pressure energy of the motive fluid into a high-speed jet, then uses that jet to drive a second fluid. "Jet Pump" may refer to two related but not identical types of equipment in different fields: 1. Industrial jet pump / eductor: Consists of a nozzle, suction chamber, throat, and diffuser section, with no moving parts in the body. Can be used for gas-liquid or liquid-liquid ejection. This is the meaning adopted in this article and for the GW series products on this site. 2. Domestic shallow-well or deep-well jet pump: Typically combines a centrifugal pump, nozzle, and venturi assembly into a complete water supply unit. The motor and impeller first establish circulating motive water, and the jet assembly then generates suction. Both utilize high-speed jets and low-pressure entrainment, but the equipment boundaries differ. Before selecting a product, confirm whether you need an industrial ejection and mixing device or a complete well water supply unit. II. What Are the Components of a Jet Pump? Component Primary Function Motive Fluid Inlet Receives water, liquid, steam, or gas with sufficient flow rate and pressure Nozzle Reduces the flow area, converting pressure energy into kinetic energy of a high-speed jet Suction Inlet & Suction Chamber Connects to the low-pressure medium and provides a passage for it to enter the main jet Throat / Mixing Tube Allows the motive fluid and suction fluid to exchange momentum and form a relatively uniform mixed flow Diffuser Section Gradually expands the flow passage, reduces the mixed flow velocity, and recovers part of the static pressure Housing & Connections Withstands pressure, secures internal structure, and connects upstream and downstream piping The nozzle outlet area, throat area, and the area ratio between them directly affect suction capacity, allowable back pressure, efficiency, and cavitation resistance. Industrial selection cannot rely solely on connection diameter. III. How Does a Jet Pump Work? Figure 2: The motive fluid enters the nozzle from the left, the suction fluid enters the suction chamber from above, the two fluids mix in the throat, and exit through the diffuser section on the right. The complete working process of a jet pump can be divided into five steps: 1. Motive Fluid Entry An external pump or process system delivers motive fluid with a certain pressure and flow rate into the jet pump. At this stage, the fluid is typically in a relatively high static pressure, low velocity state. 2. Nozzle Acceleration and Low-Pressure Zone Creation As the motive fluid passes through the converging nozzle, the flow area decreases, velocity increases significantly, and static pressure drops accordingly. When the high-speed jet enters the suction chamber, a low-pressure zone forms near the nozzle outlet. The phenomenon often summarized as the "Venturi effect" is only part of this process; a jet pump truly achieves transport through jet entrainment, turbulent mixing, and momentum transfer. 3. Entrainment of the Second Fluid When the pressure in the suction chamber is lower than the pressure in the container or pipeline holding the suction fluid, the pressure difference drives gas or liquid through the suction inlet. The suction fluid can be air, oxygen, ozone, process gas, water, or chemical solution. 4. Mixing and Momentum Transfer in the Throat The high-speed motive jet transfers part of its momentum to the suction fluid. The two fluids shear, break up, and mix in the suction chamber and throat, gradually approaching a common velocity. In gas-liquid applications, proper design helps disperse the gas into fine bubbles; in liquid-liquid applications, it enhances dilution and mixing. 5. Diffusion and Discharge After the mixed flow enters the gradually expanding diffuser section, it decelerates, and part of the kinetic energy is recovered as static pressure. The recovered outlet pressure must overcome the back pressure caused by installation depth, downstream piping, valves, and equipment to maintain stable operation. The energy path can be summarized as: Motive fluid pressure energy → High-speed kinetic energy in the nozzle → Entrainment and mixing → Partial pressure recovery in the diffuser A jet pump does not create energy out of nothing. Increasing suction capacity or overcoming higher discharge back pressure typically requires more motive flow, higher inlet pressure, or a more suitable nozzle-throat combination. IV. What Are the Types of Jet Pumps? 1. Liquid-Gas Jet Pump Uses pressurized liquid as the motive fluid to entrain air, oxygen, ozone, or other gases. Suitable for wastewater aeration, oxidation, ozone dosing, and gas-liquid mass transfer. The typical applications of the GW series in water treatment fall into this category. 2. Liquid-Liquid Jet Pump Uses one liquid to entrain another liquid. Can be used for chemical dosing, dilution, mixing, circulation, and drainage. When selecting, always provide the density, viscosity, temperature, and corrosivity of the suction liquid. 3. Gas-Gas or Steam Ejector Uses compressed gas or steam to entrain low-pressure gas. Commonly used for vacuum generation, tail gas extraction, and process gas transport. The compressible flow, critical pressure, and noise calculations differ from those of liquid-driven jet pumps and require specialized design. 4. Well Jet Pump System A centrifugal pump provides circulating motive water, and the nozzle-venturi assembly provides suction. Can be divided into shallow-well and deep-well types. It is related in principle to industrial motionless ejectors, but the system configuration, performance indicators, and selection methods differ. V. What Are the Applications of Jet Pumps? Introduction of air, pure oxygen, or ozone in wastewater treatment; Jet aeration and high-efficiency gas-liquid mixing; Chemical suction, dilution, and inline blending; Tank circulation, homogenization, and anti-sedimentation mixing; Transport of corrosive, solids-laden, or hard-to-access fluids where rotating equipment is impractical; Industrial vacuum generation, exhaust, and tail gas recovery; Downhole jet lift in oil production; Well water supply, irrigation, and local boosting systems. When used for aeration, the jet pump is only one part of the system. The circulation pump, gas supply method, operating water depth, terminal nozzle, tank flow field, and control strategy collectively determine oxygen transfer and energy consumption. A single "maximum gas suction rate" cannot substitute for system design. VI. Advantages and Limitations of Jet Pumps Key Advantages No moving parts in the body: Simple structure, minimal mechanical wear, suitable for continuous operation and hard-to-maintain locations; Simultaneous suction and mixing: Gas or liquid contacts the motive fluid immediately upon entry; Strong media adaptability: With appropriate material selection, can handle corrosive or solids-containing media; Flexible installation: Can be installed in main line, bypass, external to tank, or combined with aeration systems; Good sealing: Design eliminates leakage points associated with shaft seals; Easy parallel operation and regulation: Multiple units can be combined to accommodate zoned and variable-load conditions. Key Limitations A stable motive fluid supply is essential; the system still requires a pump, compressor, or high-pressure process source; Energy conversion involves losses; not all operating conditions are more energy-efficient than mechanical pumps; Suction capacity is highly sensitive to inlet pressure, motive flow, suction inlet pressure, and discharge back pressure; Nozzle or throat clogging and wear will alter performance; Excessively low suction pressure may cause cavitation, resulting in noise, vibration, and capacity loss; When media properties or operating conditions change significantly, the performance curve must be re-evaluated. VII. Key Parameters Affecting Jet Pump Performance 1. Motive flow rate and inlet pressure: Determine the energy available for conversion; 2. Target suction capacity: Distinguish between gas suction rate and liquid suction rate; they cannot be used interchangeably; 3. Suction inlet absolute pressure: Includes natural suction, pressurized gas supply, suction lift, and piping losses; 4. Discharge back pressure: Composed of installation depth, downstream piping, and equipment resistance; 5. Nozzle-to-throat area ratio: Affects entrainment ratio, pressure rise ratio, efficiency, and cavitation margin; 6. Media properties: Density, viscosity, temperature, gas state, solids content, and corrosivity; 7. Altitude and environmental conditions: Affect atmospheric pressure, natural suction capacity, and gas volumetric flow; 8. Suction piping: Excessive length, undersized diameter, too many elbows, insufficient valve opening, or leaks all reduce capacity. VIII. How to Select the Right Jet Pump? Follow this selection sequence: 1. Clearly identify what the motive fluid and suction fluid each are; 2. Determine the target suction rate, mixing objective, or oxygenation target; 3. Provide motive flow rate, inlet pressure, and temperature; 4. Calculate suction inlet absolute pressure, suction lift, and suction piping loss; 5. Calculate discharge back pressure, including water depth and all downstream resistances; 6. Initially select nozzle, throat, and equipment model based on performance curves; 7. Verify cavitation, materials, connections, installation space, and maintenance conditions; 8. Calculate the flow, head, power, and regulation range of the supporting motive equipment; 9. During commissioning, measure inlet pressure, motive flow, suction rate, and discharge pressure. For the GW series model range, gas/liquid suction parameters, connection sizes, and selection data sheets, please refer to the GW Series Ejector Selection Guide on this site. IX. Common Operating Issues and Troubleshooting Symptom Common Causes Recommended Checks No gas or liquid suction Insufficient motive pressure, excessive back pressure, suction line blockage or leakage Measure pressures at all three connections; check valve positions and airtightness Low suction capacity Low motive flow, nozzle wear, high suction resistance Verify operating point; inspect nozzle and suction line Increased noise or vibration Cavitation, unstable two-phase flow, loose supports Check absolute pressure and cavitation margin; inspect fixtures Insufficient discharge pressure Damaged diffuser, off-design operation, changed downstream resistance Inspect internal structure and recalculate system resistance Gradual performance decline Scaling, deposition, clogging, or corrosion Establish flushing and periodic inspection schedules X. Frequently Asked Questions (FAQ) 1. Does a jet pump require a motor? An industrial jet pump body typically does not require a motor, but it must be supplied with pressurized motive fluid by external equipment. If the circulation pump is counted as part of the complete system, the system still requires energy input. 2. Are a jet pump and a venturi tube the same thing? Not exactly the same. Both involve acceleration and pressure reduction caused by flow passage contraction, but a complete jet pump also includes an independent suction inlet, suction chamber, mixing throat, and diffuser section, and uses momentum exchange to continuously entrain a second fluid. 3. Can a jet pump handle both gas and liquid suction? Yes, but gases and liquids differ in density, compressibility, and flow characteristics. Corresponding performance data and configurations must be used; air suction parameters cannot be directly applied as liquid suction parameters. 4. Is a jet pump a self-priming pump? A jet pump can use its jet to generate suction capability, but whether "self-priming" is achieved depends on system configuration, initial filling, sealing, and installation conditions. Industrial eductors are not the same type of complete machine as self-priming well pumps with accumulator tanks on the market. 5. Is a jet pump highly efficient? Its advantages lie primarily in reliability, no moving parts, and the ability to simultaneously perform suction and mixing, rather than having the highest pumping efficiency under all operating conditions. Compare the overall system's power consumption, mass transfer effectiveness, maintenance costs, and operational reliability. 6. Why is discharge back pressure so important? A jet pump can only recover part of the pressure in the diffuser section. Excessive discharge back pressure compresses the available pressure differential, causing reduced suction capacity and, in severe cases, complete cessation of ejection. XI. Conclusion The core of a jet pump is not rotating machinery, but rather four continuous processes: nozzle acceleration, low-pressure entrainment, throat mixing, and diffuser pressurization. The motive fluid transfers energy and momentum to the suction fluid, enabling the device to accomplish suction, mixing, and transport without internal moving parts. For water treatment and industrial mixing projects, reliable selection must simultaneously establish the three pressure boundaries — motive inlet, suction inlet, and discharge outlet — and comprehensively evaluate flow rate, media, nozzle-throat geometry, cavitation, and materials. Selecting a jet pump based solely on pipe diameter or "maximum gas suction rate" often fails to yield a stable operating point.

What is a Venturi Injector Used for? Venturi injector is mainly used to mix and transfer one fluid into another by creating vacuum with a high-speed jet—especially for aeration and oxygenation. Primary Uses Water and Wastewater Treatment Aeration / oxygen transfer (air, blower-assisted, and pure oxygen), including aerobic biodegradation oxygen transfer. Advanced oxidation and disinfection with ozone (ozone dosing; ozone off-gas recycle to aeration ponds). Gas–liquid two-phase mass transfer and mixing (and related liquid–liquid mixing). Agricultural irrigation fertigation; iron/manganese removal oxygenation; flotation gas injection; river/lake/pond reoxygenation and aquaculture oxygenation. Pumping and Vacuum Technology Liquid-jet / steam-jet vacuum, hydraulic vacuum (e.g. siphon pipelines), eductors for pumping and conveying (sludge, sand, powder). Waste Gas Treatment and Process Technology Venturi scrubbers for flue-gas cleaning. How It Works Pressurized motive water jets through a nozzle, creating vacuum that draws in air/oxygen (or another fluid). The two streams mix instantly as fine bubbles/droplets for efficient mass transfer, then discharge for aeration, agitation, or further mixing. Industry Applications Venturi injector also used in coking, landfill leachate, chemical, dyeing, food, pharma, leather, desulfurization slurry oxidation, flue-gas treatment, and similar processes.

URL: https://cd-greenwater.com/chinese/Ozone-dosing-selection.html - Canonical: https://cd-greenwater.com/chinese/Ozone-dosing-selection.html - Language: zh-CN - Source: chinese/Ozone-dosing-selection.html - Description: 射流器用于臭氧投加的设计要素，分析水深、气水比、进水压力对臭氧传质效率的作用，综合平衡投资与运行成本。 射流器用于臭氧投加的设计要素 臭氧的需要量和气体投加量由客户根据具体项目的试验数据和臭氧制造商的臭氧气体浓度决定。本文解决在臭氧供气量，浓度保证和供气压力一定的情况下，臭氧传质的设计要素问题。 1. 臭氧转移效率ηo3 ηo3=臭氧需要量/臭氧供给量 臭氧传质受水深，气水比，停留时间，水质，PH，水温，水压，臭氧浓度等一系 列因素影响。水质，PH，水温由客户的 具体情况决定。在射流器选型过程中需要考虑的是，气水比，停留时间的选择及效率优化问题。 2. 水深 水深对臭氧转移效率的影响是显而易见的。水越深，臭氧转移效率越高，反之亦然。但是，水越深，意味着基建投资越大 3. 气水比 气水比指的是射流器吸入的臭氧气量与动力水量之比。在水深和射流器进口工作压力一定的条件下，气水比越小，臭氧转移效率越高。在供气量一定时，实际传递到水中的臭氧量越多。这就意味着可以使用更小规格的臭氧机和较少的氧气供应。但气水比越小，在供气量一定的情况下，循环水量就越大，射流器所使用的水泵规格型号就大，配套功率也较高。 4. 进口工作压力 在水深和气水比一定的情况下，射流器进口工作压力越大则臭氧转移效率越高，相应的射流器循环水泵的配套功率会越高。 因此，设计选型时需要在保证臭氧投加效果的前提下，将水深，气水比、进出口工作压力与总体运行成本结合起来综合平衡，将运行成本控制在最低。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 臭氧投加方案｜射流器提升臭氧传质效率 -

Description: 厂内渗漏集水井深井排污难题与泥浆泵局限，以及射流泥浆泵无转动部件、可水下作业、可配置冲泥系统自动排污等优势，改善水电站集水井清污劳动条件。 射流泵在电站集水井排污中的应用简介 集水井深井排污问题 厂内各渗漏水及其它漏水均排至渗漏集水井，大量污泥随之而入。 在多泥砂河流上，每次机组检修时有大量泥砂沉积于检修排水井井底。 多年来，一直没有一个很好的办法解决集水井深井排污问题;以往主要是靠人工清污。 集水井深达几十m，工作环境十分恶劣，并且井下作业非常不便，工作效率极低。 泥浆泵排污的局限 为改善劳动条件，有的电站设计中曾采用泥浆泵或灰渣泵，在不同程度上可以抽送一定泥浆，但是也存在许多问题。 首先离心泵因受吸出高度的限制，使用时必须安放在极低位置，但集水井长期积水，若泥浆泵安装在井内，将会被积水淹没。 所以只有在排泥时临时安放，并且还需人工冲污，给清污工作带来麻烦。 其次，由于泥砂磨损，泥浆泵有时发生机械故障。因此，有的电站即使设计了泥浆泵排污装置，有时也不得不采用人工清污。 鉴于上述原因，研究一套可靠的深井排泥装置是十分必要的。 射流泵的特点 射流泵没有转动部件，结构简单，工作可靠。 安装维护方便。 因此被广泛应用于水利、电力、化工、给排水、污水处理、供热、通风和制冷等部门。 尤其在高温、高压、易爆、易燃、潮湿和深水等恶劣条件下，优点更为显著。 但射流泵效率低，用作真空泵时极限真空度受到工作液体汽化压力限制，特别是运行范围狭窄，稍偏离最优工况，效率即将降低，有时甚至会出现倒流现象。 产品图： 射流泵在水电站中的应用条件 中、高水头水电站为射流泵提供了可靠的工作水源，电站中调相、制动等使用的压缩空气也可以作为液气射流泵的压力气源。射流泵以其独特的优点，应用于水电站中的各个系统。 射流泥浆泵深井排污的特殊优点 用射流泥浆泵运行深井排污除具有射流泵的一般优点外，还具有以下特殊优点:可以抽吸较大直径的固体; 可以在水下作业，具有很大的灵活性; 配置一套完善的冲泥系统后可以自动排污，不需人工井下作业。 因此，使用射流泥浆泵进行深井排污，大大改善了运行和检修人员的工作条件，较好地解决了集水井排污问题。 工程应用情况 利用射流泵装置进行厂内集水井排污，国外有这方面的报道，国内葛洲坝船闸集水井排污也使用了射流泵装置。 公司信息 公司网站：https://www.cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 喷射泵是什么及其工作原理 -

Description: 系统解答喷射泵是什么、喷射泵如何工作，介绍喷嘴、吸入室、喉管与扩散段的作用，以及气液、液液喷射泵的应用、优缺点和选型要点。 喷射泵是什么？喷射泵如何工作？ 喷射泵（Jet Pump），也称射流泵、射流器、引射器或 Eductor/Ejector，是利用一股具有压力的动力流体卷吸并输送另一股低压被吸流体的设备。动力流体通过喷嘴加速后，静压降低，在吸入室形成低压区；被吸流体因此进入设备，并在喉管内与动力流体交换动量、充分混合；混合流最后进入扩散段，速度降低，部分动能转化为压力能后排出。 工业喷射泵本体通常没有叶轮、电机或其他运动部件。它需要由外部水泵、压缩机或高压工艺流体提供动力，因此尤其适合气液混合、液液混合、曝气、加药、抽真空和难维护工况。 一、什么是喷射泵 喷射泵是一种依靠流体射流的动量传递实现抽吸、混合、增压或输送的流体设备。与离心泵通过旋转叶轮持续向液体做功不同，喷射泵把动力流体已有的压力能转化为高速射流，再用这股射流带动第二股流体。 "Jet Pump"在不同领域中可能指两类相关但不完全相同的设备： 1. 工业喷射泵/引射器：由喷嘴、吸入室、喉管和扩散段组成，本体无运动部件，可用于气液或液液引射。这是本文及本站 GW 系列产品所采用的含义。 2. 家用浅井或深井喷射泵：通常把离心泵、喷嘴和文丘里组件组合成一套供水装置。电机和叶轮先建立循环动力水，再由喷射组件产生抽吸。 两者都利用高速射流和低压卷吸，但设备边界不同。选择产品前，应先确认需要的是工业引射与混合设备，还是完整的井水供水机组。 二、喷射泵由哪些部件组成？ 部件 主要作用 动力流体入口 接收具有足够流量与压力的水、液体、蒸汽或气体 喷嘴 缩小流通面积，把压力能转化为高速射流的动能 吸入口与吸入室 连接低压介质，并为其进入主射流提供通道 喉管/混合管 让动力流体与被吸流体交换动量并形成较均匀的混合流 扩散段 逐渐扩大流道、降低混合流速度并恢复部分静压 壳体与接口 承压、固定内部结构并连接上下游管路 喷嘴出口面积、喉管面积以及两者的面积比会直接影响吸入能力、允许背压、效率和抗汽蚀性能。工业选型不能只看接口口径。 三、喷射泵如何工作 图2：动力流体由左侧进入喷嘴，被吸流体由上方进入吸入室，两股流体在喉管内混合并经右侧扩散段排出。 喷射泵的完整工作过程可以分为五步： 1. 动力流体进入 外部水泵或工艺系统把具有一定压力和流量的动力流体送入喷射泵。此时流体通常处于相对高静压、较低流速状态。 2. 喷嘴加速并产生低压区 动力流体通过收缩喷嘴时，流通面积减小，流速显著升高，静压随之下降。高速射流进入吸入室后，在喷嘴出口附近形成低压区。 常被概括为"文丘里效应"的现象只是这一过程的一部分；喷射泵真正实现输送，还依赖射流卷吸、湍流混合和动量传递。 3. 卷吸第二股流体 当吸入室压力低于被吸流体所在容器或管路的压力时，压差推动气体或液体经吸入口进入。被吸流体可以是空气、氧气、臭氧、工艺气体、水或药液。 4. 在喉管内混合和传递动量 高速动力射流把部分动量传递给被吸流体。两股流体在吸入室和喉管内剪切、破碎与混合，逐渐趋向共同速度。气液工况中，合理结构有助于把气体分散为细小气泡；液液工况中，则可加强稀释与混合。 5. 扩压并排出 混合流进入逐渐扩大的扩散段后减速，部分动能恢复为静压。恢复后的出口压力需要克服安装水深、下游管路、阀门和设备造成的背压，才能保持稳定运行。 可以用一条能量路径概括： 动力流体压力能 → 喷嘴内的高速动能 → 卷吸与混合 → 扩散段中的部分压力恢复 喷射泵不会凭空产生能量。提高吸入量或出口背压，通常需要更多动力流量、更高进口压力或更合适的喷嘴—喉管组合。 四、喷射泵有哪些类型？ 1. 液—气喷射泵 以加压液体作为动力流体，吸入空气、氧气、臭氧或其他气体，适合污水曝气、氧化、臭氧投加和气液传质。本站 GW 系列在水处理领域的典型应用属于这一类。 2. 液—液喷射泵 以一种液体卷吸另一种液体，可用于药剂投加、稀释、混合、循环和排水。选型时应特别提供被吸液体的密度、黏度、温度和腐蚀性。 3. 气—气或蒸汽喷射器 利用压缩气体或蒸汽卷吸低压气体，常用于抽真空、尾气抽吸和工艺气体输送。其可压缩流动、临界压力和噪声计算与液体动力喷射泵不同，需要专门设计。 4. 井用喷射泵系统 由离心泵提供循环动力水，喷嘴—文丘里组件提供抽吸，可分为浅井式和深井式。它与工业无运动部件引射器原理相关，但系统构成、性能指标和选型方法不同。 五、喷射泵有哪些应用？ 污水处理中的空气、纯氧或臭氧引入； 射流曝气与高效气液混合； 药液吸入、稀释和在线混配； 槽罐循环、均质和防沉积搅拌； 腐蚀性、含固体或不便放置旋转设备的流体输送； 工业抽真空、排气和尾气回收； 石油生产中的井下射流举升； 井水供应、灌溉和局部增压系统。 用于曝气时，喷射泵只是系统的一部分。循环泵、供气方式、工作水深、末端喷嘴、池体流场和控制方式共同决定氧传递和能耗，不能用单一"最大吸气量"代替系统设计。 六、喷射泵的优点与局限 主要优点 本体无运动部件：结构简单，机械磨损少，适合连续运行和难维护位置； 能同时抽吸和混合：气体或液体进入后即可与动力流体快速接触； 介质适应性强：选用合适材质后，可处理腐蚀性或含悬浮物介质； 安装方式灵活：可采用主管、旁路、池外或与曝气系统组合安装； 密封性好：结构可避免轴封带来的泄漏点； 容易并联与调节：可通过多台组合适应分区和变负荷工况。 主要局限 必须有稳定的动力流体，系统仍需要水泵、压缩机或高压工艺源； 能量转换存在损失，并非所有工况都比机械泵节能； 吸入量对进口压力、动力流量、吸入口压力和出口背压非常敏感； 喷嘴或喉管堵塞、磨损会改变性能； 吸入压力过低可能发生汽蚀，产生噪声、振动和能力下降； 介质物性或工况变化较大时，需要重新校核性能曲线。 七、影响喷射泵性能的关键参数 1. 动力流量与进口压力：决定可供转换的能量； 2. 目标吸入量：应区分吸气量和吸液量，不能互相套用； 3. 吸入口绝对压力：包括自然吸气、正压供气、吸入高度和管路压损； 4. 出口背压：由安装水深、下游管路和设备阻力共同构成； 5. 喷嘴与喉管面积比：影响吸入比、压升比、效率和汽蚀裕量； 6. 介质性质：密度、黏度、温度、气体状态、固体含量与腐蚀性； 7. 海拔与环境条件：影响大气压、自然吸气能力和气体体积流量； 8. 吸入管路：过长、过细、弯头过多、阀门开度不足或漏气都会降低能力。 八、如何选择合适的喷射泵？ 建议按以下顺序选型： 1. 明确动力流体和被吸流体分别是什么； 2. 确定目标吸入量、混合目标或充氧目标； 3. 提供动力流量、进口压力和温度； 4. 计算吸入口绝对压力、吸入高度及吸入管压损； 5. 计算出口背压，包括水深和所有下游阻力； 6. 根据性能曲线初选喷嘴、喉管和设备型号； 7. 校核汽蚀、材质、接口、安装空间和维护条件； 8. 计算配套动力设备的流量、扬程、功率和调节范围； 9. 调试时实测进口压力、动力流量、吸入量和出口压力。 GW 系列的型号范围、吸气/吸液参数、接口尺寸和选型数据表，可继续参阅本站的《GW系列射流器选型指南》。 九、常见运行问题与检查方法 现象 常见原因 建议检查 不吸气或不吸液 动力压力不足、背压过高、吸入管堵塞或漏气 测量三个接口压力，检查阀位和气密性 吸入量低 动力流量偏小、喷嘴磨损、吸入阻力大 核对工作点，检查喷嘴与吸入管 噪声或振动增大 汽蚀、两相流不稳定、支架松动 核对绝对压力与汽蚀裕量，检查固定件 出口压力不足 扩散段受损、工况偏离设计点、下游阻力变化 检查内部结构并重新计算系统阻力 性能逐步下降 结垢、沉积、堵塞或腐蚀 制定冲洗和定期检查计划 十、常见问题（FAQ） 1. 喷射泵需要电机吗？ 工业喷射泵本体通常不需要电机，但必须由外部设备提供具有压力的动力流体。若把循环泵计算在完整系统内，系统仍然需要能量输入。 2. 喷射泵和文丘里管是一回事吗？ 不是完全相同。两者都涉及流道收缩导致的加速和降压，但完整喷射泵还包含独立吸入口、吸入室、混合喉管和扩散段，并利用动量交换持续卷吸第二股流体。 3. 喷射泵能吸气也能吸液吗？ 可以，但气体和液体的密度、可压缩性及流动特征不同，必须使用对应的性能数据和结构，不能把吸空气参数直接当作吸液参数。 4. 喷射泵是自吸泵吗？ 喷射泵可以利用射流产生吸入能力，但"自吸"是否成立取决于系统结构、初始充液、密封性和安装条件。工业引射器与市场上带储压罐的自吸井用泵不是同一类整机。 5. 喷射泵的效率高吗？ 它的优势主要是可靠、无运动部件并能同时完成抽吸与混合，而不是在所有工况下都具有最高泵送效率。应比较整个系统的动力消耗、传质效果、维护成本和运行可靠性。 6. 为什么出口背压如此重要？ 喷射泵在扩散段只能恢复部分压力。出口背压过高会压缩可用压差，导致吸入量下降，严重时会停止引射。 十一、结论 喷射泵的核心不是旋转机械，而是喷嘴加速、低压卷吸、喉管混合和扩散增压四个连续过程。动力流体把能量和动量传递给被吸流体，使设备在没有内部运动部件的情况下完成抽吸、混合和输送。 对于水处理和工业混合项目，可靠选型必须同时建立动力入口、吸入口和出口三个压力边界，并结合流量、介质、喷嘴—喉管结构、汽蚀和材质综合判断。只按管径或"最大吸气量"选择喷射泵，往往无法得到稳定工作点。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 喷射洗涤器 | 气体洗涤除尘设备-成都绿水科技有限公司 -

Description: 同一工况下对比微孔曝气、MTS射流、传统射流与GW射流曝气：气泡大小、气液接触时间、搅拌强度、结垢堵塞与维修成本，帮助污水厂高效选型。 曝气设备怎么选？微孔曝气、传统射流与GW射流曝气传质效果对比 污水处理好氧工艺选型时，常见方案包括微孔曝气、MTS射流曝气、传统射流曝气和GW射流曝气。很多人会问：哪种曝气设备氧传质效率更高？高盐废水能不能用？后期维修成本会不会失控？本文按统一对比维度，帮助工程人员快速完成曝气设备选型。 一、先看结论：曝气选型比的是什么 在同一水质、气源、气压、温度等条件下，单位时间内氧分子传质系数一定。因此，真正拉开差距的不是“能不能充氧”，而是以下因素能否同时做对： 1. 气泡大小（比表面积）——气泡越小，气液接触面积通常越大 2. 气液接触时间——氧气在水中停留、扩散越久，传质越充分 3. 混合搅拌强度——紊动越强，界面更新越快，溶解氧分布越均匀 4. 维修频率及难易程度——是否易结垢、堵塞，能否不停水检修 再结合设备材质、结构在污水中的实际表现，就能判断哪类曝气器更适合你的工况。 二、四类曝气设备传质效果对比表 对比项 微孔曝气 MTS射流曝气 传统射流曝气 GW射流曝气 气泡大小 小 大 大 小 气液接触时间 随水深变化 随水深变化 吸气口至池底+气泡上升 最长（含管道输送与二次喷射扩散） 混合搅拌强度 一般（靠气体上升） 强（水气喷射） 有限（出口无喷嘴） 强（池底增效喷嘴二次射流） 高盐废水适应性 不适合，易结垢堵塞 不适合，易结垢堵塞 不适合，易结垢堵塞 适合，无明显水气界面，口径大不易堵 传质效率 初期高，随使用衰减 不高 不高 高且更稳定 维护特点 维护成本高 堵塞后需放水维修 易结垢堵塞 正确安装下水下免维护，主要维护池外水泵 三、微孔曝气：初期效率高，长期衰减与维护成本要算清 微孔曝气的优势是气泡小，初期传质效率高。气液接触时间会随水深变化而变化；搅拌主要依靠气体上升，搅拌力一般。 需要注意的是：微孔曝气存在水、气界面，不适合盐度较高废水，容易结垢、堵塞。传质效率会随使用时间增加而降低，维护成本高。若项目更看重长期稳定运行和低维护，这一点必须纳入全生命周期成本评估。 四、MTS射流曝气：搅拌力强，但传质与检修短板明显 MTS射流曝气气泡较大，气液接触时间随水深变化；搅拌依靠水气喷射，搅拌力强。同样因存在水、气界面，不适合盐度较高废水，容易结垢、堵塞。 整体传质效率不高。一旦堵塞，通常只能放水维修，停机影响和维护难度都更大，更适合对检修窗口要求不严、水质结垢风险较低的场景。 五、传统射流曝气：结构简单，但气泡大、搅拌有限 传统射流曝气气泡大；气液接触时间为吸气口至池底，再加上气泡上升到液面的时间。设备出口没有喷嘴，搅拌强度有限。 同样存在水、气界面，不适合盐度较高废水，容易结垢、堵塞，传质效率不高。若项目需要更高氧利用率、更强池内混合，往往要升级到带增效喷嘴的高效射流方案。 六、GW射流曝气：接触时间最长，高盐工况与低维护更友好 GW射流曝气气泡小。气液接触时间从吸气口处开始，包括横向、竖向管道中的输送时间，以及通过增效喷嘴喷射后气泡在水中扩散和上升的时间——在各类曝气装置中，其气液接触时间最长。 增效喷嘴在池底进行二次射流喷射，搅拌力强。设备不存在明显水、气界面，可适合盐度较高废水；喷嘴口径大，不易结垢、堵塞，传质效率高。 正确安装条件下，水下部分通常不需要维护维修，只需对池外水泵进行日常维护或维修。对提标改造、高盐工业废水、希望减少放空检修的污水厂，GW射流曝气往往是更稳妥的选型方向。 七、选型建议：按工况匹配，而不是只看名义效率 1. 若更看重初期细气泡和短期氧利用率，可评估微孔曝气，但要预留结垢堵塞与效率衰减带来的维护预算。 2. 若池内需要较强喷射搅拌，但水质结垢风险高或难以放水检修，应谨慎选择MTS或传统射流。 3. 若同时关注气泡细度、最长气液接触时间、二次射流搅拌、高盐适应性和水下低维护，优先对比GW射流曝气。 曝气设备选型的核心目标始终是：在目标溶解氧和混合效果下，实现稳定、可维护、全周期成本可控的充氧方案。 八、常见问题 FAQ 影响曝气设备传质效果的主要因素有哪些？ 在同一水质、气源、气压、温度等条件下，单位时间内氧分子传质系数一定。影响传质效果的主要因素是气泡大小（比表面积）、气液接触时间和混合搅拌强度；工程选型还要同步评估维修频率及难易程度。 高盐废水更适合哪种曝气方式？ 微孔曝气、MTS射流曝气和传统射流曝气都存在水、气界面，高盐工况下更容易结垢、堵塞。GW射流曝气无明显水气界面，喷嘴口径大，更适合盐度较高废水。 为什么说GW射流曝气的气液接触时间最长？ 因为它的接触过程从吸气口就开始，覆盖管道输送，再到池底增效喷嘴二次喷射后的气泡扩散与上升，路径更完整，因此气液接触时间通常长于其他曝气装置。 公司信息 公司网站：https://www.cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 气体喷射泵 -

Description: 简单介绍井用射流泵如何灌泵，包括停电检查、加水排气、启动观察、重复补水及无法引水的常见原因。 射流泵如何灌泵？ 井用射流泵灌泵，就是在启动前通过泵体上的灌水口，把泵壳和吸水管尽量充满清水并排出空气。关闭灌水口后短时间启动，观察压力和出水情况；如果没有建立稳定水流，应立即停机、再次补水和排气，不能让水泵长时间干转。 注意：本文所说的灌泵适用于带电机、叶轮和喷射组件的浅井或深井射流泵。工业射流器或引射器本体没有叶轮，通常依靠外部动力流体工作，不采用相同的灌泵方法。 灌泵前需要准备什么？ 与水泵系统相容的清水； 漏斗或干净的加水软管； 用于拆装灌水塞的扳手； 水泵制造商说明书； 必要的手套和护目镜。 开始前应确认吸水管、接头、止回阀或底阀已经安装好。吸水侧漏气或止回阀失效时，即使反复加水，水泵也可能无法完成引水。 射流泵灌泵步骤 1. 切断电源 关闭水泵电源并确认设备不会意外启动。不要在电机通电时拆卸灌水塞或检查泵体。 2. 释放系统压力 打开附近的水龙头或排水阀，释放管路中的残余压力。确认压力表回落后再操作灌水口。 3. 打开灌水口 找到泵壳上方的灌水塞或灌水口，缓慢拆下。不同型号的位置可能不同，应优先查看制造商说明书。 4. 缓慢加入清水 通过灌水口缓慢加水，让水进入泵壳和吸水管。等待气泡排出，并继续加水，直到灌水口附近的水位不再明显下降。 深井射流泵或较长吸水管可能需要多次补水。不要使用含泥沙、杂物或腐蚀性物质的水进行灌泵。 5. 装回灌水塞 确认泵体已经充满水后，重新安装并拧紧灌水塞。密封应可靠，但不要过度用力损坏螺纹或密封件。 6. 短时间启动水泵 恢复电源并启动水泵，观察压力表和出水口。正常情况下，水泵会逐渐建立压力，并形成连续、稳定的水流。 7. 没有出水时立即停机 如果短时间内仍未出水、压力没有上升，或者水泵发出异常声音，应立即停机。待设备安全后重新打开灌水口，再次补水和排气。 不要让没有水的射流泵持续运转。干转可能损坏机械密封、叶轮和其他部件。允许的试运行时间应以设备说明书为准。 为什么射流泵灌泵后仍然不上水？ 常见原因包括： 1. 吸水管漏气：接头、密封带、管道或泵壳存在漏点； 2. 底阀或止回阀失效：停机后水倒流回井内，泵体无法保持充水； 3. 水位过低：实际吸程超过射流泵的工作范围； 4. 吸水管堵塞：滤网、底阀或管路被泥沙和杂物堵塞； 5. 灌水不充分：泵壳或吸水管内仍有大量空气； 6. 压力开关或阀门设置不正确：出口阀门关闭或控制系统未正常工作； 7. 喷嘴或文丘里组件堵塞：结垢、泥沙或异物影响射流抽吸； 8. 叶轮或机械密封损坏：水泵无法建立所需压力或持续吸入空气。 如果反复灌水仍无法建立水流，应停止尝试，并检查吸水侧气密性、底阀、井内水位及喷射组件。无法确认原因时，应联系水泵维修人员。 常见问题 射流泵每次启动前都要灌泵吗？ 正常密封且止回阀工作良好的系统，首次启动或维修排空后通常需要灌泵，日常启动不应每次重新加水。如果水泵频繁失去引水，应检查漏气或水倒流问题。 可以让射流泵空转来自动吸水吗？ 不建议。大多数井用射流泵需要先充水，长时间干转可能使机械密封过热并损坏水泵。 灌泵需要加多少水？ 没有统一容量。应把泵壳和吸水管尽量充满，直到灌水口水位稳定。长管路或深井系统通常需要更多水和多次补充。 工业射流器需要这样灌泵吗？ 通常不需要。工业射流器本体没有叶轮，它依靠外部水泵或其他压力源提供动力流体。启动时应先确认动力流体已经建立规定流量和压力，并按系统操作规程排气、开阀和调试。 结论 射流泵灌泵的关键是：先断电，向泵壳和吸水管加满清水，充分排出空气，密封灌水口后再短时间启动观察。如果无法建立稳定水流，应立即停机检查，避免水泵干转。 不同品牌和型号的结构、阀门位置及允许试运行时间不同，实际操作应始终以设备制造商说明书为准。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 射流泵用于机组调相压水-成都绿水科技有限公司 -

Description: 射流曝气器利用文丘里引射与高速射流强化气液传质。本文详解其工作原理、结构特点、氧利用率优势及在市政污水、工业废水、纯氧曝气、臭氧投加等场景的应用。 射流曝气器到底是什么？一篇讲清原理、优势、场景 很多人第一次听到“射流曝气器”这个词，第一反应往往是：它和普通曝气到底有什么区别？ 其实你可以把它理解成一种更擅长“吸气、混合、搅拌、传氧”的曝气方式。它不是简单地往水里打气，而是借助高速水流把空气、纯氧甚至臭氧吸进来，再通过喷射和循环，让气体更充分地进入水体。 说得更直白一点，射流曝气器真正厉害的地方，不只是会曝气，而是它能把吸气、混合、循环和传质这几件事一起做掉。 一、射流曝气器是怎么工作的 如果把它的工作过程拆开来看，基本可以分成两步。 第一步，是先把水“喷快”。 动力水在水泵作用下通过喷嘴高速喷出，压力能变成速度能，这时候射流器内部就会形成负压区。空气或者氧气会被这个负压“吸”进去，然后和高速液流在射流器内部先完成一次混合，形成比较细、比较均匀的气泡。 第二步，是把已经混好的水气混合流送到池底再喷出去。 这时候喷流不只是自己往前冲，它还会把周围更多的水一起带动起来，形成明显的循环、搅拌和卷吸作用。这样一来，氧气和污水、污泥接触得更充分，氧的传递效率也就更高。 所以，射流曝气器的核心逻辑不是“冒泡”，而是“高速引射 + 强制混合 + 二次喷射 + 循环传质”。这也是它和很多传统曝气方式最大的区别。 结构图： 二、它为什么比传统曝气更有吸引力? a. 传氧效率通常更高 气泡越细、分布越均匀，氧气越容易进入水里。 现有资料里提到，自吸式和鼓风加压式射流曝气在合适工况下，氧利用率可以做到 30% 到 45%；纯氧射流曝气更高，可以达到 90% 以上；而在臭氧应用测试中，臭氧利用率甚至可以做到 99% 以上。 对污水处理项目来说，这一点很关键。因为供氧效率上去了，系统运行就更从容，处理效果也更容易稳定下来。 b. 不只是曝气，还能把混合和循环一起做好 很多污水池的问题，不只是氧不够，而是混合不均匀、局部有死角、污泥悬浮不好。 射流曝气器因为有明显的喷流和卷吸能力，往往能把搅拌、循环、增氧这几件事一起做掉。对于氧化沟、推流池、混合池、氧化塘这类池型来说，这种能力很实用。 c. 系统相对简单，改造也更灵活 以资料里的 GWQ/B 射流曝气器为例，系统主要由水泵、文丘里射流器、增效喷嘴和必要管道组成，整体结构比较紧凑。 如果是鼓风加压型方案，还可以结合原来的鼓风机或压缩机系统来做升级改造。换句话说，不少项目并不需要把整套系统全部推倒重来，而是可以在原有基础上提升性能。 4. 维护相对更省事 传统曝气头用久了，比较容易遇到堵塞、老化、开裂这些问题，很多时候还得停水、放水之后才能检修。 而现有资料里多次提到，射流曝气方案更适合不停水、不放水改造，维护重点更多集中在水泵等设备上。对很多老旧污水厂来说，这一点很有现实意义，因为它直接关系到检修难度、停机时间和运维成本。 5. 噪音更低，对工况变化也更友好 资料中提到，部分安装方式下，射流曝气系统的噪音比较低，有些甚至可以接近静音。 同时，它还能根据负荷变化去切换空气、风机气源或者纯氧气源，也能通过变频调节来适配不同工况。所以面对水量、水质波动的时候，系统的适应性通常会更强。 6. 对工艺运行还有一些附加好处 在纯氧射流曝气资料里还提到，这类系统可减少泡沫和臭味，改善污泥沉降性，降低污泥膨胀风险，并有助于提高既有污水厂的处理能力。 尤其是在高浓度废水、臭氧尾气回用、纯氧曝气这类要求更高的场景里，这些附加优势会更明显。 三、射流曝气器一般用在哪些地方? 从这次整理到的资料来看，射流曝气器的应用范围其实挺宽，不只是传统意义上的污水池曝气。 1. 市政污水和工业废水处理 这是最常见、也是最核心的应用方向。 现有案例和资料覆盖了生活污水、制药废水、垃圾渗滤液、印染废水、食品废水、造纸废水、焦化废水、酒精废水和化工废水等多种类型。凡是需要提高供氧效率、改善池内混合效果、减少改造停机时间的项目，都很适合重点考虑 2. 纯氧曝气和高负荷强化处理 如果项目本身负荷高、处理指标紧、池容又有限，那么纯氧射流曝气就会特别有价值。 它能把纯氧更高效地打进水里，比较适合提标改造、扩容升级，以及高浓度有机废水处理这类场景。 3. 臭氧投加和臭氧尾气回用 这次资料里和臭氧相关的内容非常多，既有设计指南，也有大量工程业绩。 这说明射流器在臭氧投加、臭氧尾气回用、强化氧化这些场景里，已经有比较成熟的应用基础。对于深度处理项目来说，这类能力很有吸引力。 4. 河道复氧、除铁除锰和供水预处理 除了污水厂，射流器也可以用在河道湖泊复氧、地下水除铁除锰、供水系统充氧等方向。 因为它的本质是强化气液混合和传质，所以只要场景里对“把气体更高效地送进液体”有需求，它就有发挥空间。 5. 气浮、加药、抽真空和工业混合 虽然这些不全是严格意义上的“曝气”，但底层逻辑是一样的，都是利用射流器的引射和混合能力。 工程业绩里还能看到它被用于气浮加气、液气射流真空泵、药剂投加、罐体循环搅拌、粉体和气体输送等工业用途。也就是说，它本质上不只是一个曝气设备，更像是一种流体混合平台。 工程样例图： 四、怎么理解它真正的工程价值 如果从工程角度看，射流曝气器真正有价值的地方，不只是某一个参数更高一点，而是它把供氧、混合、循环、搅拌这些原本分散的功能，尽量整合进了一套流体系统里。 这样做的好处很直接： 1. 系统更紧凑 2. 改造思路更灵活 3. 混合和传氧更容易兼顾 4. 运维压力相对更小 尤其是对老旧污水站来说，如果原来的曝气头已经衰减，风量也不够，池内供氧还不均匀，那么射流曝气往往不是单纯“换个设备”这么简单，而更像是一条提效和改造路线。 五、总结 简单总结，射流曝气器是一种以文丘里引射和二次射流强化传质为核心的高效曝气技术。 它真正的优势，不只是增氧快，而是能够同步完成吸气、混合、循环和搅拌。所以在市政污水、工业废水、纯氧曝气、臭氧投加、河道复氧等场景里，它都有比较强的适应性。 如果一个项目正面临提标、扩容、降噪、减少检修、提升氧利用率这些需求，那么射流曝气器确实是一条很值得认真评估的技术路线。 六、联系方式 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 射流曝气器选型设计服务｜优化投资与运行成本 -

Description: 成都绿水科技提供射流曝气器选型与设计服务，综合考虑工作压力、水深、数量、吸气压力、海拔、气液比及水质条件。 射流曝气选型的影响因素 在需氧量确定的条件下，射流器的选型是一个平衡投资成本与运行成本的优化过程，成都绿水科技有限公司可为客户提供射流器选型、布置方面的设计服务，以达到投资和运行成本优化配置的目的，综合降低污水处理成本。 在具体的选型过程中，我们考虑的因素主要有以下几个方面: 1. 射流器的工作压力 : 通过水流量越大，射流器的工作压力越大，吸入的气量就越多。在特定充氧量需求条件下，所需的射流器数量较少，设备购置成本较低，但由于压力增大，水泵功率增大，动力效率降低，运行成本会增加。 2. 工作水深 : 射流器可适用于任何水深，水深增加时氧转移效率和动力效率都得到提高，水系功率可以降低，运行成本下降，如图二所示。但水深增加会使基建成本增加。 3. 射流器的数量 : 增加射流器的数量，可以使所需的配套功率降低，投资会增加，但运行成本会下降。 4. 吸气压力与海拔: : 射流器的吸气量在一个大气压的条件下确定。吸气压力低于一个大气压时按修正系数=(真空压力/1个大气压)进行修正。吸气压力高于一个大气压时按修正系数=[(表压+1个大气压)/1个大气压]”进行修正。 5. 气液比 : 气液比越大，单位水量吸入的气体越多，动力效率提高但氧转移效率会下降，但气液比达到60%~80%以后，动力效率增加缓慢。原因在于气泡直径和在水中分布状态是气液比越小越好。 因此，在纯氧曝气时，不主张单纯追求动力效率来提高气液比，而是要有一个最优平衡点，来兼顾氧气利用率和氧气传递功耗。 除以上因素外，水温、盐度、操作溶解氧浓度、水的化学性质都会对射流器的型号、数量及配套功率选择产生重要影响。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 射流曝气器用于屠宰废水处理_充氧效率高_运行稳定 -

Description: 射流曝气器在印染废水处理中的应用展开，介绍其工作原理、工艺优势、适用场景及选型要点，帮助企业提升曝气效率、改善处理效果并降低运行风险。 射流曝气器印染废水处理案例 在印染废水处理领域，曝气系统的稳定性与充氧效率，直接影响生化处理效果、运行能耗以及后期维护成本。对于许多已经运行多年的污水处理站来说，传统微孔曝气装置在长期使用后，往往会出现堵塞、开裂、效率下降等问题，进而影响出水达标和系统稳定运行。针对这一行业痛点， 射流曝气器在印染废水处理改造项目中的应用，展现出较强的工程适配性和实际运行价值。 都绿水科技有限公司在江苏常州实施的一个中小型印染废水处理改造项目，就是较有代表性的案例之一。该项目原有曝气池采用微孔曝气装置，但随着使用时间增长，微孔管逐渐老化，出现堵塞、开裂等现象，导致曝气效率下降，出水难以达到设计指标。同时，原系统在检修更换微孔曝气装置时，需要停水放水，检修结束后还要重新培养污泥，不仅周期长，而且维护成本较高，给客户日常运行管理带来了较大压力。 项目图 在此背景下，项目方选择采用射流曝气器对原有系统进行改造。相较于传统微孔曝气方式，射流曝气器在安装方式、运行维护和系统适配方面具有明显优势。其系统主要由水泵、连接管道、射流器 和增效喷嘴构成，管道布置相对简单，且可实现不停水、放水安装，大大降低了改造过程对原有污水处理系统运行的影响。 从工艺设计参数来看，该项目设计处理水量为3000m3/d ，曝气时间为24h。曝气池尺寸为40m×19.5m×5.4m ，共分为5格，超高0.6m， MLVSS为2500mg/L。设计进水COD为800～1200mg/L ，设计出水要求为≤100mg/L。结合项目实际需求以及设备性能参数，最终选用4套GW3600射流曝气器，配套N40增效喷嘴108个。其中一套GW3600配套 37kW 水泵，流量550m3/h 、扬程15m；其余三套分别配套30kW水泵，流量480m3/h 、扬程14m。 这种选型方式并非标准化套用，而是根据项目池型、水量、水质以及客户要求进行量身定制。也正因为如此，射流曝气器不仅能够满足曝气充氧需求，还能兼顾池内搅拌效果，避免能耗浪费，实现设备配置与处理目标的有效匹配。 从实际运行效果来看，该项目在设备投运后，处理水量保持在3000m3/d 。实测进水COD为 800～1000mg/L，出水COD 稳定达到≤80mg/L，优于原设计出水指标。项目总使用功率为127kW，对应COD降解量为2.16～2.76t/d ，单位降解能耗为1.41～1.1kWh/kgCOD。从这些运行数据可以看出，射流曝气器在印染废水处理改造项目中，不仅能够满足处理效果要求，还具备较好的能耗控制表现。 除了处理效果和能耗表现外，射流曝气器在运行稳定性和维护便利性方面同样具有明显优势。项目运行后，曝气池内搅拌与充氧更加均匀，不存在死区，有利于维持生化系统稳定运行。同时，射流曝气器噪音较低，成功解决了原有鼓风曝气系统噪音大的问题，改善了现场运行环境。更重要的是，射流器与水泵均安装在池外，能够在不停水、不放水的条件下完成安装和维护，显著降低停机风险。 从维护角度来看，射流器和增效喷嘴本身基本不需要维修，仅需定期对水泵进行保养即可。这一点与传统微孔曝气系统形成鲜明对比。传统微孔曝气器一旦堵塞或老化，不仅检修复杂，还会影响整个池体运行；而射流曝气器的核心部件维护需求低，检修工作量小，长期运行的综合维护成本明显更低。这对于印染企业尤其重要，因为连续稳定生产通常意味着污水处理系统必须保持较高的在线率和可靠性。 从行业应用角度分析，印染废水具有有机物浓度波动大、处理负荷变化明显、对曝气与混合要求较高等特点。单纯依赖传统曝气方式，在设备老化或工况变化后，往往容易出现充氧不足、局部死区、检修困难等问题。而射流曝气器通过“充氧+搅拌”协同作用，能更好适应印染废水处理中的复杂工况，特别适合老旧污水站提标改造、曝气系统更新以及需要不停产改造的项目场景。 综合本案例可以看出，射流曝气器在印染废水处理中的应用价值主要体现在以下几个方面：一是安装灵活，可实现不停水放水施工；二是搅拌充氧均匀，有助于减少曝气死区；三是噪音低，改善现场运行环境；四是维护工作量小，显著降低后期检修成本；五是出水稳定，能够满足国家污水综合排放标准一级要求。 对于正在进行印染废水处理升级、新建污水站配套，或计划替换原有微孔曝气系统的企业来说，射流曝气器提供了一种兼顾处理效果、维护便利与综合运行成本的解决方案。尤其是在环保标准持续提高、企业更加重视稳定达标与节能降耗的当下，选择适合实际工况的曝气设备，已经成为工业废水处理项目成败的关键因素之一。 如果您正在关注 射流曝气器在印染废水处理中的应用 ，或希望了解更适合自身项目的曝气改造方案，基于具体水量、水质和池体条件进行设备选型与系统设计，将更有助于提升项目运行效果与投资回报。 公司网站：https://www.cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 射流曝气系统厂家｜高效增氧节能污水处理设备 -

Description: 文丘里射流器安装方式、安装注意事项、启动停机要点及相关技术资料说明，涵盖管路布置、故障排查与运行维护建议。 射流器安装指南 成都绿水科技有限公司 一、概述 文丘里射流器是一种高效射流装置。带压工作（动力）流体从射流器入口进入喷射腔形成高速喷射流体，高速流体产生压降使待加入物质（液/气）从吸入口吸入并进入工作流体，混合液经扩散段到达出口，流速减慢、压力回升（但低于进口压力）。进出口之间只要有很小的压差即可形成负压吸入液体或气体。 射流曝气系统结构包括射流器、增效喷嘴（二次喷射器）、循环水泵等，具备适于各种水深、免维修、安装施工方便、可以不放水施工改造等特点。同一套设备可使用空气、风机加压空气或纯氧等不同气源，以满足处理负荷波动。 二、安装方式 2.1 池外式安装 池外式安装根据水泵主要分为管道泵、立式泵和自吸泵干式安装方式。适用于新建、改建的地上式曝气池和地下式曝气池结构，安装十分快捷方便，管道简单。仅需对水泵进行维护，射流器和增效喷嘴长期运行不需维修。 图a：卧式泵干式安装 图b：自吸泵干式安装 图c：鼓风加压式安装 图a 卧式泵干式安装示意 图b 自吸泵干式安装示意 图c 鼓风加压式安装示意 2.2 管道式安装 若管道上的动力水量和压力在所选射流器的工作范围下，射流器可直接安装在主管道上；在动力流量和压力不变时，射流器吸入恒定量的气体或液体。 若主管道上的动力流量大于所选射流器的工作流量时，则可把射流器安装在旁路上，通过主管流量调节阀对经射流器的流量、压力进行调节，从而对吸气量或液量进行调节。 图e 主管式安装 图f 旁路式安装 2.3 GWQ/B射流曝气器安装形式 GWQ/B射流曝气器主要由水泵、文丘里射流器、增效喷嘴及二次射流导流筒（备选）组成。系统简单，无需鼓风机、复杂管道等设备；结构紧凑，安装方便，维护时仅需维修水泵，维修一台设备不需要停止其他设备的运行。 GWQ：潜水射流曝气器，可采用吊装方式入池； GWB：射流曝气池外干式安装。 GWQ潜水射流曝气器吊装 GWB射流曝气池外干式安装 2.4 GW一体化射流曝气机组 GW射流一体化设备是用液体作工作介质，利用文丘里原理，在液体高速喷射时产生负压，使水泵吸入的混合液（污水+污泥）在射流器内与空气/氧气进行射流混合形成超饱和氧混合液的集装式设备。体积小、结构紧凑可移动，适用于各种改造或新建曝气充氧场合，也可用于不停水、不放水改造项目。 GW一体化射流曝气机组安装示意 三、自吸高度与吸气口布置 自吸射流曝气射流器安装在池外时，射流器吸气口高度应该高于水面。 如果射流器安装在池内，或者安装在池外但吸气口高度低于水面，需要将射流器吸气口延长至水面以上。 四、增效喷嘴在曝气池内的布置 增效喷嘴喷射方向的服务距离一般为5 m～6 m。选型时先按机组配置表确定喷嘴规格与数量，再按池型布置筛选。 4.1 池宽≤6 m 在池宽方向布置一排增效喷嘴即可满足喷射方向的服务距离；池长方向按各型号允许的喷嘴间距布置（例如N70间距≤3.5 m，N70B/N70C/N60间距≤3 m，N40/N30间距≤2.5 m）。 4.2 池宽＞6 m 在池宽方向需布置多排增效喷嘴，排数可按 N＝池宽/5 m（取整）估算；喷嘴数量按排数分配后，再校核池长方向间距是否满足要求。 五、安装后的启动与停机要点 正确安装完成后，须按正确阀门状态启停，尤其鼓风加压方式，防止水泵泵体进气或风机/风管进水。 5.1 自吸射流曝气 启动：按水泵说明书开启水泵，确认正向运转；潜水泵可测自吸气口风速，池外泵可观察电机转向；吸气口吸气明显则运转正常。 停机：按水泵说明书关停水泵即可。 5.2 鼓风加压射流曝气 设备安装后初始状态：水泵、风机停机；鼓风进气阀FI关闭；自吸旁通阀SI全开；鼓风机放空阀FV开启。 1. 使用鼓风加压模式逐台启动水泵时，未启动水泵所带射流器的自吸旁通阀必须开启。 2. 禁止不开启射流泵而单独使用鼓风机通过射流器曝气。 3. 确认自吸工作正常后，再开启鼓风进气阀FI与鼓风机，关闭自吸旁通阀SI，逐步关闭放空阀FV。 4. 停机：系统停机时先打开SI排气，再停风机并关闭FI，最后停水泵；不可在风机运转且FI开启时停水泵。 5. 鼓风机停机时，未停机/未启动水泵对应射流器均应关闭FI并打开SI，防止虹吸使池水进入鼓风管道。 阀门开闭参考表 情况 FO FV FI SI PI PO 水泵停 / 风机停 闭 开 闭 开 闭 闭 水泵开 / 风机停 闭 开 闭 开 开 开 水泵开 / 风机开 开 闭 开 闭 开 开 水泵停 / 风机开（故障） 开 闭 闭 开 闭 闭 FO鼓风机出口阀；FV放空阀；FI鼓风进气阀；SI自吸旁通阀；PI/PO水泵进/出口阀。 5.3 射流加臭氧 设备安装后，水泵停机，臭氧进气阀关闭。启动水泵并确认自吸正常后，关闭自吸空气阀，再开启臭氧进气阀。停止时先关闭臭氧进气阀，再按说明书关闭水泵和阀门。 6、纯氧/潜水设备安装现场注意 工程实践（焦化污水纯氧曝气试验）表明： 1. 供氧设备、汇流排和启动柜就位后铺设供氧管道，扩散器用吊车吊入污水池； 2. 为防止压坏原有空气曝气管，宜在水下设置支撑平台； 3. 安装入水时建议短暂关闭鼓风，排除水气流湍动影响，使设备正确到位； 4. 氧气相关设备与管道须按氧气性质进行清洗脱脂处理，并符合氧气管道安装规范。 7、基坑降水用射流泵安装（相关应用） 7.1 轻型井点 射流泵及配套离心泵布置于基坑地面之上：各井点管通过总管接入射流泵吸入口，离心泵采用清洁水循环。射流泵极限抽吸深度约10 m，通常降水深度约8 m左右。 安装调试流程：安装好地面离心泵、射流泵、水箱及地面管道；确定井点布置，钻孔后沉没井点管并灌填砂滤料；试验确保井点管不漏气漏水后投入使用。 7.2 喷射井点（射流深井泵） 将射流泵安置于喷射井管内（一体化射流深井泵），埋深按降水深度确定；抽吸深度通常可按低于射流泵4～6 m左右考虑，一般需配套高压水泵。 安装调试流程：安装地面离心泵、水箱及地面管道；确定井点布置，钻孔后沉没喷射井点管并灌填砂滤料；试验确保无漏气漏水后投入使用。 8、与安装相关的故障排查 射流器本身不能产生压差，而是依靠动力源经射流器及管道的压损形成压差工作。不能正常工作时，可适当改变安装位置以满足压差要求，并建议进出口装压力表。 1. 进口压力低、压差不够：提高水泵扬程或增设加压泵； 2. 配套进出连接管太小：改用与射流器进出口相一致的管道； 3. 连接管道有堵塞物：清除堵塞物； 4. 吸气管道不净或被堵塞：吹扫干净，清除堵塞物； 5. 长期运行内部污垢导致尺寸变化：通常可用30%盐酸浸泡约30分钟清洗，再用清水冲洗。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 射流器工作原理 -

Description: 简单解释引射器如何利用动力流体、喷嘴、吸入室、喉管和扩散段产生真空，并介绍影响真空度的主要因素。 引射器如何产生真空？ 引射器利用高压动力流体通过喷嘴形成高速射流。动力流体加速后，喷嘴出口和吸入室附近的静压降低；当这里的压力低于被抽容器的压力时，气体便从吸入口进入引射器。被吸入的气体与动力流体在喉管内混合，随后经过扩散段减速并恢复部分压力，最后一起排出。气体持续被带走，被抽容器内的压力随之下降，于是形成真空。 引射器产生真空的四个步骤 1. 动力流体进入喷嘴 具有一定压力和流量的水、空气或蒸汽进入引射器。动力流体可以由水泵、压缩机或蒸汽系统提供。 2. 喷嘴把压力转换为速度 动力流体通过收缩喷嘴时，流通面积变小，流速迅速升高，同时静压下降。高速射流在吸入室形成一个低压区域。 3. 低压区吸入气体 当吸入室压力低于被抽设备或容器内的压力时，压差推动气体进入吸入口。高速射流不断卷吸并带走这些气体，使容器内的气体分子逐渐减少，内部绝对压力持续下降。 4. 混合流经过扩散段排出 动力流体和被吸气体在喉管中交换动量并混合。混合流进入逐渐扩大的扩散段后速度降低，部分动能转化为压力能，使混合流能够克服出口背压并排出。 整个过程可以概括为： 动力流体压力能 → 喷嘴高速射流 → 形成低压并卷吸气体 → 喉管混合 → 扩散段恢复压力并排出 真空是被"吸"出来的吗？ 严格来说，引射器不是直接制造一个空洞，而是利用压力差和高速射流不断移走容器内的气体。当气体被排出的速度大于外界气体泄漏或工艺气体产生的速度时，容器内压力就会降低，形成低于大气压的真空状态。 因此，引射器能够达到的最终真空度，取决于抽气能力与系统漏气量、蒸发气量及其他气体负荷之间的平衡。 引射器的主要结构 部件 作用 动力入口 接收高压水、压缩空气或蒸汽 喷嘴 把压力能转换为高速射流 吸入口 连接需要抽真空的容器或管路 吸入室 形成低压区并接收被吸气体 喉管 让动力流体和被吸气体交换动量、完成混合 扩散段 降低流速、恢复部分压力并推动混合流排出 哪些因素会影响真空度？ 1. 动力流体压力和流量 动力压力或流量不足时，喷嘴无法形成设计要求的高速射流，吸入室压力就不能充分降低。 2. 喷嘴和喉管尺寸 喷嘴出口面积、喉管面积及其比例决定引射器的抽气量、真空度和允许出口压力。尺寸不匹配时，即使动力压力很高，也不一定能够获得理想真空。 3. 出口背压 出口管路过细、过长、堵塞或下游压力过高，会妨碍混合流排出。背压超过设计范围时，抽气量会下降，严重时可能失去真空。 4. 吸入管路阻力 吸入管过长、管径过小、弯头过多或阀门开度不足，都会增加阻力，使设备入口测得的真空与被抽容器内的实际真空不同。 5. 系统漏气 法兰、阀门、密封件、仪表接口或焊缝漏气，会不断把外界空气带入系统。漏气量过大时，引射器可能始终无法达到目标真空度。 6. 气体性质和温度 被抽气体的分子量、温度、含湿量和可凝性都会影响引射性能。使用蒸汽引射器时，动力蒸汽品质和冷凝条件也非常重要。 为什么引射器不需要运动部件？ 引射器不依靠叶轮或活塞抽气，而是使用动力流体本身的能量完成加速、卷吸和输送。因此，引射器本体通常没有运动部件，具有结构简单、维护量小、可处理潮湿或腐蚀性气体等特点。 但是，"没有运动部件"并不表示不消耗能量。动力水、压缩空气或蒸汽都需要由外部系统提供，其能耗应纳入整套真空系统计算。 引射器无法建立真空怎么办？ 可以依次检查： 1. 动力流体压力和流量是否达到设计值； 2. 动力流体阀门和吸入口阀门是否正确开启； 3. 喷嘴、喉管或出口管路是否堵塞； 4. 出口背压是否超过允许范围； 5. 吸入管路和被抽系统是否漏气； 6. 真空表量程、安装位置和读数是否正确； 7. 实际气体负荷是否超过引射器设计抽气量； 8. 喷嘴是否磨损、腐蚀或结垢。 常见问题 引射器和真空泵有什么区别？ 机械真空泵通过旋转或往复部件排出气体；引射器利用高速动力流体卷吸气体。引射器结构简单，但需要持续消耗动力流体。 引射器可以使用哪些动力流体？ 常见动力流体包括加压水、压缩空气和蒸汽。应根据目标真空度、抽气量、气体性质、现场能源条件和材质要求选择。 动力压力越高，真空度一定越高吗？ 不一定。引射器需要在设计工作点附近运行。动力压力过低会降低性能，但盲目提高压力也可能增加能耗，并不一定继续提高真空度。喷嘴、喉管、气体负荷和出口背压必须相互匹配。 引射器能达到绝对真空吗？ 不能。实际系统始终存在气体负荷、泄漏、流动损失和设备性能极限。工程上应以绝对压力或规定条件下的真空度表示目标，不能把"真空"理解为压力等于零。 结论 引射器产生真空的核心，是让动力流体通过喷嘴形成高速射流，在吸入室建立低压区，并持续卷吸、混合和排出被抽气体。能否达到目标真空度，不仅取决于动力压力，还取决于喷嘴与喉管结构、抽气负荷、吸入阻力、出口背压及系统密封性。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 在线技术手册｜成都绿水科技 -

Description: 增效喷嘴是射流曝气与流体混合系统中的二次强化部件，前端射流器完成一次混合后，通过二次射流、卷吸引流和紊流强化，提升循环能力、氧利用率与混合均匀性。 增效喷嘴原理、优势及应用价值 一、增效喷嘴概述 增效喷嘴是射流曝气与流体混合系统中的关键功能部件，其作用并非单纯完成流体喷出，而是在前端射流器完成一次气液混合后，进一步对混合流进行二次射流强化，从而提升系统的循环能力、混合效率和传质效率。 在典型应用中，文丘里射流器负责形成负压吸入空气、氧气或其他介质，并完成第一次混合；增效喷嘴则将混合流以优化的喷射流态释放到池体、容器或管道中，通过引流、卷吸和紊流强化，带动更多周围液体参与循环。正因其在系统后端承担“二次强化”的作用，增效喷嘴成为提升整体运行效率的重要组成部分。 二、增效喷嘴工作原理 增效喷嘴的工作原理可概括为"一次混合、二次强化"。 第一阶段，由前端文丘里射流器完成一次混合。动力水进入射流器后在喷射腔内形成高速流体，随着流速升高、静压降低，空气、氧气或其他被吸入介质进入主流体，并在射流器内部完成初级气液混合。 第二阶段，由增效喷嘴完成二次强化。经过初级混合后的流体通过增效喷嘴射入主体液体环境，在喷嘴结构和喷流流态作用下形成更强的卷吸与引流效应。根据现有本地资料，增效喷嘴可吸引约 4 至 5 倍于工作流体的周围液体共同参与混合，从而形成更大范围的循环流场和更高强度的二次混合过程。 从流体机理角度看，该过程与文丘里效应、伯努利原理以及喷流卷吸效应具有一致性。流体在收缩段加速后形成低压区，进而带动周围流体进入混合扩散段，实现流量放大、循环强化和传质提升。由此可见，增效喷嘴的核心价值不在于“喷出”，而在于“通过喷射带动更多流体共同参与混合”。 三、增效喷嘴的主要优势 1. 提高氧利用效率 增效喷嘴通过二次射流强化，使气液混合流进入主体液体后继续形成卷吸与紊流，有助于扩大氧气与水体的接触范围，提高氧从气相进入液相的效率。对于污水生化处理系统而言，这意味着更高的氧利用率和更稳定的供氧效果。 2. 节约系统能耗 增效喷嘴本身不直接提供动力，但能够通过优化喷射流态和引流能力，更充分地利用已有动力水能量。在相同泵功条件下，若系统能够获得更大的循环范围、更好的混合效果和更高的氧利用率，则整体运行能效将得到提升。 3. 扩大搅拌服务面积 增效喷嘴在喷射过程中可带动更大范围液体流动，从而扩大单套设备的实际服务区域。对于需要保持污泥悬浮、减少沉积、增强池内循环的系统而言，这一特点能够显著改善整体流场分布。 4. 改善混合均匀性 通过强化二次混合和循环路径，增效喷嘴有助于提高池内溶解氧分布均匀性、污泥浓度均匀性及整体液体流态稳定性。对于对混合均匀度要求较高的曝气池、反应池或容器系统，该优势尤为明显。 5. 安装简便，维护量低 现有本地资料显示，N 系列增效喷嘴具有安装简便、免维修等特点。作为静态流体部件，其结构相对简单，无复杂传动机构，在材质和工况匹配合理的前提下，通常具备较低的维护需求和较高的长期运行稳定性。 6. 布置灵活，适配改造项目 增效喷嘴可根据池型条件灵活布置，并可适用于不停水、不放水改造场景。对于既有污水处理设施的提标、扩容和节能改造，该特点具有较高工程价值。 四、增效喷嘴的应用场景 1. 污水处理曝气系统 增效喷嘴最典型的应用场景是射流曝气系统，尤其适用于城市生活污水和工业废水处理中的生化曝气过程。与文丘里射流器组合使用时，可同时实现传氧、搅拌和循环强化。 2. 需要大范围循环搅拌的池体或容器 对于调节池、均化池、反应池及其他需要较强循环和防沉积能力的液体处理系统，增效喷嘴可通过扩大喷流作用范围和强化流场分布，提升整体搅拌效果。 3. 老系统提效改造项目 在既有系统中，若存在供氧不足、混合不均、循环能力弱或改造窗口有限等问题，增效喷嘴由于安装方便、布置灵活，适合作为提效改造中的关键强化部件。 4. 对混合均匀度要求较高的工况 在需要提高液体均匀度、强化循环紊流、防止局部沉积的工艺场景中，增效喷嘴同样具有较强适用性。这类需求不仅存在于污水处理中，也广泛存在于其他液体混合和循环应用中。 项目图： 五、增效喷嘴的工程价值 从系统角度看，增效喷嘴并非单纯的末端出流部件，而是决定混合流进入主体液体后能否充分释放能量、形成有效循环和实现高效传质的重要节点。 其工程价值主要体现在以下几个方面： 对于射流曝气系统而言，如果前端射流器解决的是“吸入并初步混合”的问题，那么增效喷嘴解决的则是“如何在主体液体中高效释放并放大混合效果”的问题。二者配合，才能更完整地体现系统的整体性能。 六、结语 增效喷嘴是提升射流系统性能的重要功能部件。其核心作用在于通过二次射流强化、卷吸引流和循环放大，提高氧利用率、改善混合均匀性、扩大搅拌服务面积，并优化系统整体能效表现。 在关注曝气效率、混合效果、运行能耗及改造便利性的工程项目中，增效喷嘴不应被简单视为普通配件，而应作为系统性能优化的重要组成部分加以评估和配置。 七、联系方式 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ### 蒸汽喷射器 | 蒸汽喷射真空机组 | 气体喷射真空机组 -

URL: https://cd-greenwater.com/chinese/steam-ejector.html - Canonical: https://cd-greenwater.com/chinese/steam-ejector.html - Language: zh-CN - Source: chinese/steam-ejector.html - Description: 提供多级蒸汽喷射器真空系统，适用于VDU减压蒸馏、凝汽器抽不凝气及化工真空。无运动部件，耐腐蚀耐含尘，运行稳定；支持按蒸汽条件与真空度定制。 什么是蒸汽喷射器 1. 引言 在现代工业加工中，创建和维持可靠的真空环境对于优化产品质量、降低能耗以及促进复杂的化学反应至关重要。蒸汽喷射器（通常被称为蒸汽喷射真空泵或蒸汽喷射器）是一种高度专业化的固定设备，用于产生真空、压缩气体或输送工艺流体。 与依赖活塞、叶轮或旋转螺杆的传统机械真空泵不同，蒸汽喷射器利用高速蒸汽喷射来卷吸和压缩气体。对于工业客户而言，这意味着该系统完全没有内部运动部件。它是一种超可靠、重型的机械设备替代方案，尤其适用于粉尘、腐蚀性蒸汽或高温气体会迅速损坏传统机械的恶劣加工环境。无论是作为单个单元使用，还是配置成复杂的多级结构，蒸汽喷射器仍然是全球稳健工艺工程的基石。 2. 工作原理 蒸汽喷射器的工程结构基于热力学和流体力学的基本原理——特别是文丘里效应和气体动力学。整个运行过程可分为三个不同的、连续的阶段，这些阶段均发生在装置的内部几何结构中。 第一阶段：膨胀与加速（喷嘴段） 该过程始于高压动力流体（通常为过热蒸汽或干饱和蒸汽）进入喷射器壳体。动力流体被引导通过一个精密加工的收缩-扩张喷嘴（也称为德拉瓦尔喷嘴）。当蒸汽通过喷嘴的喉部时，其静压能降低，速度增加。当蒸汽从喷嘴的扩张段进入吸入室时，它完全膨胀，加速至超音速——通常在马赫数 2 到 5 之间。 第二阶段：卷吸和动量传递（吸入和混合室） 蒸汽射流的急剧加速会在吸入室内形成一个局部极低静压区。由于该腔室内的压力远低于所连接的工艺容器的压力，工艺气体、蒸汽或空气会被自然地吸入喷射器本体。进入喷射器本体后，工艺气体与超音速蒸汽射流相遇。在混合段，发生高速动量传递：高速运动的蒸汽卷吸速度较慢的工艺分子，从而形成均匀的蒸汽和工艺气体混合物。 第三阶段：压缩和减速（扩散器段） 混合流体随后进入扩散器，该扩散器具有收缩的入口、狭窄的喉部和扩张的出口。当混合物流经扩散器扩张的扩张型腔体时，其速度被强制降低。根据伯努利原理和能量守恒定律，这种减速迫使超音速流体的动能转化为静压能。因此，混合物被压缩到远高于吸入室压力的排出压力，从而可以将其排放到冷凝器、后续的喷射器级或直接排放到大气中。 3. 蒸汽喷射器的主要优势 在比较真空技术时，工程团队经常选择蒸汽喷射器而不是液环泵、干式螺杆泵或旋转叶片系统，因为蒸汽喷射器具有一系列明显的运行和经济优势。 1. 无内部运动部件：由于该装置完全依靠流体动力学而非机械运动，因此无需润滑、磨损或更换轴承、齿轮、活塞或密封件。这直接转化为前所未有的机械可靠性和超长的检修间隔。 2. 对恶劣工艺流体具有极高的耐受性：机械泵难以应对夹带现象。蒸汽喷射器可以轻松处理湿蒸汽混合物、腐蚀性化学气体、磨蚀性颗粒物和爆炸性蒸汽，而不会发生灾难性的机械故障。 3. 低资本投入和经济的规模化：蒸汽喷射器的初始资本成本远低于同等容积容量的机械泵。对于深真空条件下的大流量应用，蒸汽喷射器是市场上性价比最高的选择。 4. 防爆且安全运行：由于蒸汽喷射器无需电气连接或摩擦产生部件即可在工艺流程中运行，因此无需昂贵的防爆外壳，即可在危险环境（例如 ATEX 0 区或 1 区）中安全运行。 5. 安装灵活紧凑：喷射器重量轻、占地面积小。它们可以水平、垂直或倾斜安装，并且通常直接悬挂在管道系统上，从而最大限度地降低结构支撑成本并节省宝贵的地面空间。 4. 主要应用领域： 蒸汽喷射器是一种用途广泛的装置，广泛应用于全球众多行业： 炼油和石油化工： 在炼油领域，原油真空蒸馏装置 (VDU) 或许是最突出的应用。为了在不引起热裂解的情况下分离重质烃，必须在低至 10 至 30 毫巴的压力下蒸馏重质常压残渣。多级蒸汽喷射器系统与中间冷凝器相结合，能够持续处理这些重质、腐蚀性和高温烃类负荷。 发电： 在火力发电厂、核电厂和联合循环发电厂中，蒸汽轮机的废气排入表面冷凝器以优化热效率。保持冷凝器内部的深度真空至关重要。蒸汽喷射器用作抽气和保压系统：在启动阶段（抽气），它们快速排出冷凝器中的空气；在正常运行阶段（保压），它们持续去除泄漏到系统中的不凝性气体，从而保持涡轮机的最佳性能。 化学和制药加工： 许多化学合成、聚合反应和药物成分提取都需要温和的低温煮沸或干燥，以防止产品降解。蒸汽喷射器可提供工业蒸发器、结晶釜、真空干燥器和脱臭装置（常见于食用油加工）所需的稳定真空。 冶金工业： 在现代炼钢中，真空脱气 (VD) 和真空氧脱碳 (VOD) 等技术用于生产高纯度低碳钢。这些工艺会释放大量高温、含尘的一氧化碳和氢气。蒸汽喷射器能够轻松应对这些恶劣的含尘气流，在几分钟内即可排出大量冶金钢包中的气体。 5. 工业案例研究 案例研究1：消除炼油厂真空蒸馏装置停机时间 背景：北美一家中型炼油厂的真空蒸馏装置采用机械式干式螺杆真空泵系统。工艺气体中含有高腐蚀性硫化物和磨蚀性催化剂细粉，导致转子卡滞和泵每4至6个月发生一次故障。每次故障都会造成数百万美元的生产损失和专门的维护费用。 解决方案：该炼油厂用定制设计的带有壳管式冷凝器的三级蒸汽喷射器系统替换了原有的机械系统。 结果：蒸汽喷射器系统成功地处理了腐蚀性化合物和催化剂细粉，且性能未受影响。该炼油厂报告称，在连续4年期间，与真空系统相关的非计划停机时间为零，预计节省了超过320万美元的维护和收入损失成本。此外，该炼油厂利用邻近锅炉装置的现有废蒸汽作为动力流体，使该系统具有很高的能源效率。 案例研究2：提升 500MW 火电厂效率 背景：某燃煤电厂由于冷凝器储气所用的液环真空泵系统老化且性能下降，导致发电效率低于最佳水平。该系统无法维持 40 mbar 的设计真空度，造成汽轮机背压升高，进而降低了电厂的净兆瓦输出功率。 解决方案：工程师为电厂改造了一套现代化的双元件两级蒸汽喷射器排气装置。双元件配置提供了 2x100% 的冗余度，允许在不停机的情况下对其中一台机组进行维护或检查。 结果：新喷射器投入使用后，立即将冷凝器真空度恢复到最佳设计参数。修正后的汽轮机背压使电厂整体发电效率提高了 0.8%，这意味着每年可节省大量燃料成本，并在不到 9 个月的运行时间内实现了投资回报。 6. 摘要及行业目标 蒸汽喷射器巧妙地运用流体动力学原理，解决了现代工程中一些最棘手的真空产生难题。它利用高压驱动蒸汽压缩和输送气体，无需任何移动部件，从而实现了机械替代方案无法比拟的运行时间和可靠性。 蒸汽喷射器几乎可以部署在任何配备锅炉系统的工厂中，但某些特定行业将其视为关键基础设施：炼油厂和石化联合企业：对于连续真空蒸馏装置至关重要，因为设备故障会导致整条生产线停产。 发电厂：需要持续清除大型表面冷凝器中的不凝性气体，以保持发电效率。 重冶金：对于大容量钢包脱气至关重要，因为高温、磨蚀性强、含尘气体的装置会迅速损坏机械部件。 对于希望最大限度地延长工艺正常运行时间、降低维护成本并建立能够处理恶劣工艺流的坚固真空基础设施的运营而言，蒸汽喷射器仍然是首选的、经过时间考验的选择。 公司信息 公司网站：https://cd-greenwater.com 技术联系电话：028-85130135 客服联系电话：18515915124 联系邮箱：jane1984@cd-greenwater.com 地址：成都市双流区西航港长城路一段191号 返回目录 --- ## Traditional Chinese Pages ### 常見問題解答(FAQ)_使用幫助_成都綠水科技 -

Language: zh-Hant - Source: Traditional-Chinese/Composition-of-ozone-jet-dosing-system.html - Description: 系統由氧氣源、動力水泵、文丘里射流器（一次射流）與池底增效噴嘴（二次射流）組成，實現臭氧負壓吸入、微泡混合與二次噴射攪拌傳質。 臭氧噴流投加系統的組成是什麼 成都綠水科技股份有限公司設計的噴流臭氧投加系統的PID流程如下： 圖中標記：1-氧氣源系統，2-動力水泵，3-文丘里射流器（一次射流），4-增效噴嘴（二次射流） A. 氧氣源系統: 主要包括液氧儲槽、汽化器、氧氣壓力調節和輸送管道或製氧機、氧氣壓力調節和輸送管道。 氧氣源系統供應臭氧產生器生產臭氧的原料氣，在特定情況下也可同時或單獨向曝氣池供氧，增加曝氣池的總充氧量。 B. 噴射曝氣器 噴射曝氣器由動力水泵提供動力水源，分為水池外部的一級文丘里射流器、安裝在水池中的二級增效噴嘴和管道，以及切換閥門。 1. 動力循環水泵為文丘里射流器吸入臭氧、水氣混合液的輸送以及增效噴嘴的二次噴射攪拌傳質提供必須的能量。 2. 文丘里射流器是整個曝氣系統的核心元件，臭氧質傳曝氣過程從這裡即行開始。臭氧在喉部被高速水流吸入，在一級文丘里射流器內形成帶有均勻微型氣泡的水氣混合液，傳質過程即行開始。水氣混合液在壓力管道中輸送至二級增效噴嘴，臭氧在水池內繼續傳質。 3. 增效噴嘴也是曝氣系統的關鍵元件，它的作用是讓帶超飽和氧的水氣混合液在池底完成二次噴射，與池中含臭氧相對較低的污水充分攪拌混合，再次進行傳質，提高臭氧轉移效率和曝氣均勻度。 4. 閥門系統的動作使曝氣過程根據水質變化調整臭氧的供氣量，同時確保臭氧管道內不會進水，確保系統運作的安全性和成本的經濟性。 C. 管路系統 1. 整個高難度廢水生化法處理+O3深度高階氧化法處理出水零排放系統的管路系統簡單，製作及維護方便。 2. 對於新建項目，動力水泵和文丘里射流器在池外佈置，射流器出口透過管道連接二級增效噴嘴。連接管道穿過牆體上的預埋孔將增效噴嘴佈置在池底。平時只需對動力水泵進行維護和維修，射流曝氣器均不需要維修和維護，性能長期運轉不衰減。 3. 對於改造項目，動力水泵和文丘里射流器在池外佈置，射流器出口連接增效噴嘴的主管道伸到牆體上方後沿著水池壁佈管，再通過支管連接佈置在池底的增效噴嘴。增效噴嘴視設計的大小可直接人工放入池底或吊裝入池底，定位後將伸出水面的連接管與主管上的支管連接起來即可。 D. 總結 噴射臭氧投加系統由氧氣源、動力水泵、文丘里射流器一次混合與池底增效噴嘴二次噴射傳質組成，並透過閥門與管路實現按水質調節供氣、防倒灌與安全經濟運作。 公司資訊 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城一段路191號 返回目錄 --- ### 成都綠水科技 -

A：噴射自吸/加壓噴射曝氣可提供更穩定的充氧能力，且系統更不易因阻塞、腐蝕導致效率衰減，進而提升生化段長期運作穩定性。 Q2：維護工作量會不會更大? A：案例表明，水泵和射流器可池外安裝，射流器與增效噴嘴免維修，主要維護水泵；檢修不需停水放水，維護更便捷。 公司資訊 公司網站：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城路一段191號 返回目錄 --- ### 成都綠水科技 - 氣體洗滌分離器 | 工業廢氣處理設備 - URL: https://cd-greenwater.com/Traditional-Chinese/Gas-Scrubbers.html - Canonical: https://cd-greenwater.com/Traditional-Chinese/Gas-Scrubbers.html - Language: zh-Hant - Source: Traditional-Chinese/Gas-Scrubbers.html - Description: 氣體洗滌分離器適用于工業廢氣，具有除塵、除臭、化學吸收(99.5%去除效率)、耐腐蝕等特點，可處理高溫、高腐蝕性等有毒有害及高濕氣體。 氣體洗滌分離器 文丘里射流洗滌器(氣體洗滌分離器)目前已被各類工業用于處理廢氣，由于射流産生負壓，可以抽吸各類高溫、粉塵、腐蝕、有毒有害等氣體，高速噴射的洗滌劑沖擊可以去除顆粒汙染物，有害氣體和臭味通過吸收和化學作用去除，可以達到很好的洗滌除塵及化學吸收的效果(99.5%)，滿足下遊工藝的使用或合格排放的要求。 作爲壹種高效廢氣處理設備，射流洗滌具備除塵能力強、廢氣和臭味去除率高、適應高濕氣體處理、耐腐蝕、不懼處理物毒性等特性，因此被廣泛用于各種工民用廢氣處理中。 爲滿足不同處理負荷的要求，射流噴嘴爲可更換型式。水氣混合液排出後通過氣液分離器氣水分離，讓排放氣體含濕量盡可能低以確保處理效果。 氣體洗滌分離器性能: 氣體洗滌分離器效率圖表: 處理能力可按客戶需求設計。 去除效率還取決于噴嘴進口壓力、顆粒負荷總量和密度等因數。 聯絡方式 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城一段路191號 返回目錄 --- ### 成都綠水科技 蒸汽噴射真空機組 | 真空/輸送解決方案 - URL: https://cd-greenwater.com/Traditional-Chinese/pump-vaccum.html - Canonical: https://cd-greenwater.com/Traditional-Chinese/pump-vaccum.html - Language: zh-Hant - Source: Traditional-Chinese/pump-vaccum.html - Description: 專業提供射流器、液體/氣體真空泵、多級蒸汽噴射真空機組，用于固液氣輸送、真空幹燥蒸餾、化工冶金環保等場景，公司是真空/輸送解決方案的供應商。 應用領域 水處理 好氧生化充氧 氣、液兩相傳質輸送 臭氧高級氧化及消毒 水力攪拌 物料投加 輸送與真空 固體/液體/氣體的輸送 液體/氣體真空泵 多級蒸汽噴射真空機組 廢氣處理與過程技術 文丘里洗滌器 填料塔 噴射洗滌器 固體/液體/氣體的輸送 利用自身抽吸輸送的原理及結構簡單可靠的特點，射流器廣泛應用于各個行業及領域。 農牧漁業：供水灌溉，與機械泵聯合工作提高能效，深井提水，鮮活魚類輸送，養殖增氧機。 交通運輸：河道海港疏浚，射流泥漿/砂漿輸送泵，射流挖泥船；船舶艙底排水排汙，艦船抽氣排熱隱身，射流推進，射流供油等。 給排水工程：輔助啓泵，提高機械泵揚程流量等性能；下水道排汙；糞便抽吸輸送轉運。 礦山冶金：礦井排水排汙，精礦水力輸送。 油氣勘探輸送：射流采油，低壓天然氣增壓輸送，鑽機中的泥漿抽排。 航空航天：發動機增大推力，射流供油，改善燃料泵性能。 固體粉末/顆粒的氣力輸送: 廣泛應用于建築、化工、輕工、冶金、礦山及發電等行業。 水利行業：與機械泵聯合工作提高能效，增加流量，提高吸程，輔助啓動，抽氣充水，造虹吸，泵房排水排淤，河道取水清淤，射流加藥等；船閘充水，魚道補水；高地灌溉，基坑排水； 電力行業：水電站技術供水，水輪機頂蓋核集水井排水，虹吸抽氣，尾水管補氣；鍋爐給水泵增壓防汽蝕，凝汽器抽氣，射流供油， 爐渣汙水排放，噴射加熱；核電站的冷卻劑射流循環系統。 化工醫藥等行業：安全可靠，適用于清潔和危險材料；可抽吸輸送有毒、易燃、易爆和具有放射性的固體/液體或溶液， 可抽吸含顆粒，有腐蝕性氣體雜質的幹/濕混合氣體，可用作混合化學反應設備。 液體/氣體真空泵 液體/氣體真空泵可單獨使用于壹些低真空場所。比如主機械泵啓動時的抽氣充水，內燃機的燃氣射流自吸； 化工醫藥環保行業裏的真空幹燥、 升華、蒸餾、結晶、提純、過濾、運輸、滅菌、回潮等工藝過程。 大氣噴射器與液體真空泵配套使用，可克服後者的極限真空度限制。 多級的氣體噴射泵最廣泛的使用爲多級蒸汽噴射真空機組，有少量的多級氣體真空泵可不需冷凝器，實現較高的真空度。 多級蒸汽噴射真空機組 蒸汽噴射器用于加工、食品、金屬冶煉、化工等諸多行業的過濾、蒸餾、吸收、混合、真空包裝、冷凍幹燥、脫水和脫氣等生産工藝。 它們將處理可冷凝和不可冷凝的氣體、蒸氣以及兩者的混合物。 相對于其他類型的真空發生裝置，蒸汽噴射真空機組由如下的優點： 1：低成本。 2：無活動部件，可靠性高。幾乎無須維修，確保優越的運行可靠性。 3：結構簡單緊湊，安裝簡易方便。 4：高真空性能。多級蒸汽噴射真空機組可以實現絕對壓力爲幾帕斯卡的真空。 5：耐腐蝕/侵蝕。可以制成幾乎任何可行的材料都可以提供最大的耐腐蝕和侵蝕 大氣式混合冷凝器: 大氣式混合冷凝器是多級蒸汽噴射真空機組的主要組成設備之壹，主要用于將前級噴射器中的可凝蒸汽冷凝，降低後級噴射器的抽吸負荷，從而降低設備的造價，提高經濟性。 大氣式混合冷凝器與蒸汽噴射泵組成的真空機組，可以實現絕對壓力爲幾帕斯卡的真空。 --- ### 成都綠水科技-技術文檔｜原理剖析·案例分享·設備選型 - URL: https://cd-greenwater.com/Traditional-Chinese/article.html - Canonical: https://cd-greenwater.com/Traditional-Chinese/article.html - Language: zh-Hant - Source: Traditional-Chinese/article.html - Description: 成都綠水科技技術文檔涵蓋原理、案例及設備，爲廢水處理、廢氣處理、真空輸送等領域提供專業解決方案。 原理 案例 設備 什麽是文丘里射流器 了解更多+ 純氧曝氣的優勢 了解更多+ 射流曝氣器結構 了解更多+ 射流曝氣器在蔗糖廢水處理中的應用 了解更多+ 射流曝氣器在垃圾滲濾液中的應用 了解更多+ 氣體洗滌分離器 了解更多+ 射流器-臭氧投加 了解更多+ 射流曝氣器 了解更多+ 壹體化汙水處理設備 了解更多+ --- ### 成都綠水科技-射流曝氣在蔗糖廢水處理中的應用 - URL: https://cd-greenwater.com/Traditional-Chinese/Jet-Aerator-Solves-Sucrose-Wastewater-Treatment.html - Canonical: https://cd-greenwater.com/Traditional-Chinese/Jet-Aerator-Solves-Sucrose-Wastewater-Treatment.html - Language: zh-Hant - Source: Traditional-Chinese/Jet-Aerator-Solves-Sucrose-Wastewater-Treatment.html - Description: 蔗糖廢水處理中存在微孔曝氣盤易堵塞、曝氣不均勻，氧利用率低等問題，射流曝氣器有充氧能力好，安裝維修簡便，噪音低、能耗低等優點。 射流曝氣器在蔗糖廢水處理中的應用 I. 工程基本概況 蔗糖廢水主要來源于生産酒精的廢水，可生化性差，粘度高，腐殖性不好，COD濃度高達100000-120000mg/L，完全采用生物法處理，工藝複雜，成本高，投資高。 結合本汙水特點，采用生物制肥技術，利用兼氧菌將産生的酒精廢醪液發酵氧化成熟的腐殖酸(液體肥)。 由于蔗糖産生的酒精汙水粘性大，微孔曝氣盤或管易堵塞、曝氣不均勻，氧利用率低，供氧能力不足，傳統的MTS射流曝氣系統氧利用率低，管道布置複雜，投資高，能耗高。 爲解決以上問題，雲南英茂糖業有限公司采購了成都綠水科技有限公司GW射流器對缺氧池進行供氧曝氣。 II. 實施情況 本工程缺氧池共設 5 座，池型及配套的射流曝氣器數量分別爲：18×18×3 m 池 2 套、25×15×4.5 m 池 3 套、20×20×3 m 池 2 套、14×14×3 m 池 2 套、15×15×4.5 m 池 2 套。 各池配套的射流泵流量分別爲: 1. 流量200m3/h，揚程18m，裝機功率15kw，數量2台； 2. 流量300m3/h，揚程18m，裝機功率22kw，數量3台； 3. 流量310m3/h，揚程22m，裝機功率30kw，數量2台； 4. 流量150m3/h，揚程22m，裝機功率15w，數量2台； 5. 流量200m3/h，揚程18m，裝機功率15kw，數量2台。 III. 運行處理效果 根據客戶原設計采用GW鼓風加壓射流曝氣方式進行供氧，而在實際運行中，不需采用鼓風加壓射流曝氣方式，只需采用GW射流自吸曝氣方式即可達到充氧效果。自投運以來：射流器具有以下顯著優點： 1. 充氧能力好，出水水質滿足液體肥要求； 2. 安裝維修簡便，水泵安裝在池外，水泵的維護和維修方便，解決了傳統微孔曝氣管易堵塞，氧利用率低，供氧能力不足，維修複雜、維修費用高的問題； 3.

Description: 射流器用於臭氧投加的設計要素，分析水深、氣水比、進水壓力對臭氧傳質效率的作用，綜合平衡投資與運行成本。 噴射器用於臭氧投加的設計要素 臭氧的需要量和氣體投加量由客戶根據特定項目的試驗數據和臭氧製造商的臭氧氣體濃度決定。本文解決在臭氧供氣量，濃度保證和供氣壓力一定的情況下，臭氧傳質的設計要素問題。 1. 臭氧轉移效率ηo3 ηo3=臭氧需要量/臭氧供給量 臭氧傳質受水深，氣水比，停留時間，水質，PH，水溫，水壓，臭氧濃度等一系 列因素影響。水質，PH，水溫由顧客的 具體狀況決定。在射流器選型過程中需要考慮的是，氣水比，停留時間的選擇及效率最佳化問題。 2. 水深 水深對臭氧轉移效率的影響是顯而易見的。水越深，臭氧轉移效率越高，反之亦然。但是，水越深，代表基建投資越大 3. 氣水比 氣水比指的是射流器吸入的臭氧氣量與動力水量之比。在水深和噴射器進口工作壓力一定的條件下，氣水比越小，臭氧轉移效率越高。在供氣量一定時，實際傳遞到水中的臭氧量越多。這就意味著可以使用較小規格的臭氧機和較少的氧氣供應。但氣水比越小，在供氣量一定的情況下，循環水量就越大，噴射器所使用的水泵規格型號就大，配套功率也較高。 4. 進口工作壓力 在水深和氣水比一定的情況下，射流器進口工作壓力越大則臭氧轉移效率越高，相應的射流器循環水泵的配套功率會越高。 因此，設計選型時需要在確保臭氧投加效果的前提下，將水深，氣水比、進出口工作壓力與總體運行成本結合起來綜合平衡，將運行成本控制在最低。 公司資訊 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城一段路191號 返回目錄 --- ### 臭氧投加方案｜射流器提升臭氧傳質效率 -

Description: 系統解答噴射泵是什麼、噴射泵如何工作，介紹噴嘴、吸入室、喉管與擴散段的作用，以及氣液、液液噴射泵的應用、優缺點和選型要點。 噴射泵是什麼？噴射泵如何工作？ 噴射泵（Jet Pump），也稱射流泵、射流器、引射器或 Eductor/Ejector，是利用一股具有壓力的動力流體捲吸並輸送另一股低壓被吸流體的設備。動力流體通過噴嘴加速後，靜壓降低，在吸入室形成低壓區；被吸流體因此進入設備，並在喉管內與動力流體交換動量、充分混合；混合流最後進入擴散段，速度降低，部分動能轉化為壓力能後排出。 工業噴射泵本體通常沒有葉輪、電機或其他運動部件。它需要由外部水泵、壓縮機或高壓製程流體提供動力，因此尤其適合氣液混合、液液混合、曝氣、加藥、抽真空和難維護工況。 一、什麼是噴射泵（What Is a Jet Pump）？ 噴射泵是一種依靠流體射流的動量傳遞實現抽吸、混合、增壓或輸送的流體設備。與離心泵通過旋轉葉輪持續向液體做功不同，噴射泵把動力流體已有的壓力能轉化為高速射流，再用這股射流帶動第二股流體。 "Jet Pump"在不同領域中可能指兩類相關但不完全相同的設備： 1. 工業噴射泵/引射器：由噴嘴、吸入室、喉管和擴散段組成，本體無運動部件，可用於氣液或液液引射。這是本文及本站 GW 系列產品所採用的含義。 2. 家用淺井或深井噴射泵：通常將離心泵、噴嘴和文丘里組件組合成一套供水裝置。電機和葉輪先建立循環動力水，再由噴射組件產生抽吸。 兩者都利用高速射流和低壓捲吸，但設備邊界不同。選擇產品前，應先確認需要的是工業引射與混合設備，還是完整的井水供水機組。 二、噴射泵由哪些部件組成？ 部件 主要作用 動力流體入口 接收具有足夠流量與壓力的水、液體、蒸汽或氣體 噴嘴 縮小流通面積，把壓力能轉化為高速射流的動能 吸入口與吸入室 連接低壓介質，並為其進入主射流提供通道 喉管/混合管 讓動力流體與被吸流體交換動量並形成較均勻的混合流 擴散段 逐漸擴大的流道、降低混合流速度並恢復部分靜壓 殼體與接口 承壓、固定內部結構並連接上下游管路 噴嘴出口面積、喉管面積以及兩者的面積比會直接影響吸入能力、允許背壓、效率和抗汽蝕性能。工業選型不能只看接口口徑。 三、噴射泵如何工作（How Does a Jet Pump Work）？ 圖2：動力流體由左側進入噴嘴，被吸流體由上方進入吸入室，兩股流體在喉管內混合並經右側擴散段排出。 噴射泵的完整工作過程可以分為五步： 1. 動力流體進入 外部水泵或製程系統把具有一定壓力和流量的動力流體送入噴射泵。此時流體通常處於相對高靜壓、較低流速狀態。 2. 噴嘴加速並產生低壓區 動力流體通過收縮噴嘴時，流通面積減小，流速顯著升高，靜壓隨之下降。高速射流進入吸入室後，在噴嘴出口附近形成低壓區。 常被概括為"文丘里效應"的現象只是此過程的一部分；噴射泵真正實現輸送，還依賴射流捲吸、湍流混合和動量傳遞。 3. 捲吸第二股流體 當吸入室壓力低於被吸流體所在容器或管路的壓力時，壓差推擠氣體或液體經吸入口進入。被吸流體可以是空氣、氧氣、臭氧、製程氣體、水或藥液。 4. 在喉管內混合和傳遞動量 高速動力射流把部分動量傳遞給被吸流體。兩股流體在吸入室和喉管內剪切、破碎與混合，逐漸趨向共同速度。氣液工況中，合理結構有助於把氣體分散為細小氣泡；液液工況中，則可加強稀釋與混合。 5. 擴壓並排出 混合流進入逐漸擴大的擴散段後減速，部分動能恢復為靜壓。恢復後的出口壓力需要克服安裝水深、下游管路、閥門和設備造成的背壓，才能保持穩定運行。 可以用一條能量路徑概括： 動力流體壓力能 → 噴嘴內的高速動能 → 捲吸與混合 → 擴散段中的部分壓力恢復 噴射泵不會憑空產生能量。提高吸入量或出口背壓，通常需要更多動力流量、更高進口壓力或更合適的噴嘴—喉管組合。 四、噴射泵有哪些類型？ 1. 液—氣噴射泵 以加壓液體作為動力流體，吸入空氣、氧氣、臭氧或其他氣體，適合污水曝氣、氧化、臭氧投加和氣液傳質。本站 GW 系列在水處理領域的典型應用屬於這一類。 2. 液—液噴射泵 以一種液體捲吸另一種液體，可用於藥劑投加、稀釋、混合、循環和排水。選型時應特別提供被吸液體的密度、黏度、溫度和腐蝕性。 3. 氣—氣或蒸汽噴射器 利用壓縮氣體或蒸汽捲吸低壓氣體，常用於抽真空、尾氣抽吸和製程氣體輸送。其可壓縮流動、臨界壓力和噪聲計算與液體動力噴射泵不同，需要專門設計。 4. 井用噴射泵系統 由離心泵提供循環動力水，噴嘴—文丘里組件提供抽吸，可分為淺井式和深井式。它與工業無運動部件引射器原理相關，但系統構成、性能指標和選型方法不同。 五、噴射泵有哪些應用？ 污水處理中的空氣、純氧或臭氧引入； 射流曝氣與高效氣液混合； 藥液吸入、稀釋和在線混配； 槽罐循環、均質和防沉積攪拌； 腐蝕性、含固體或不便放置旋轉設備的流體輸送； 工業抽真空、排氣和尾氣回收； 石油生產中的井下射流舉升； 井水供應、灌溉和局部增壓系統。 用於曝氣時，噴射泵只是系統的一部分。循環泵、供氣方式、工作水深、末端噴嘴、池體流場和控制方式共同決定氧傳遞和能耗，不能用單一"最大吸氣量"代替系統設計。 六、噴射泵的優點與局限 主要優點 本體無運動部件：結構簡單，機械磨損少，適合連續運行和難維護位置； 能同時抽吸和混合：氣體或液體進入後即可與動力流體快速接觸； 介質適應性強：選用合適材質後，可處理腐蝕性或含懸浮物介質； 安裝方式靈活：可採用主管、旁路、池外或與曝氣系統組合安裝； 密封性好：結構可避免軸封帶來的洩漏點； 容易並聯與調節：可通過多台組合適應分區和變負荷工況。 主要局限 必須有穩定的動力流體，系統仍需要水泵、壓縮機或高壓製程源； 能量轉換存在損失，並非所有工況都比機械泵節能； 吸入量對進口壓力、動力流量、吸入口壓力和出口背壓非常敏感； 噴嘴或喉管堵塞、磨損會改變性能； 吸入壓力過低可能發生汽蝕，產生噪聲、振動和能力下降； 介質物性或工況變化較大時，需要重新校核性能曲線。 七、影響噴射泵性能的關鍵參數 1. 動力流量與進口壓力：決定可供轉換的能量； 2. 目標吸入量：應區分吸氣量和吸液量，不能互相套用； 3. 吸入口絕對壓力：包括自然吸氣、正壓供氣、吸入高度和管路壓損； 4. 出口背壓：由安裝水深、下游管路和設備阻力共同構成； 5. 噴嘴與喉管面積比：影響吸入比、壓升比、效率和汽蝕裕量； 6. 介質性質：密度、黏度、溫度、氣體狀態、固體含量與腐蝕性； 7. 海拔與環境條件：影響大氣壓、自然吸氣能力和氣體體積流量； 8. 吸入管路：過長、過細、彎頭過多、閥門開度不足或漏氣都會降低能力。 八、如何選擇合適的噴射泵？ 建議按以下順序選型： 1. 明確動力流體和被吸流體分別是什麼； 2. 確定目標吸入量、混合目標或充氧目標； 3. 提供動力流量、進口壓力和溫度； 4. 計算吸入口絕對壓力、吸入高度及吸入管壓損； 5. 計算出口背壓，包括水深和所有下游阻力； 6. 根據性能曲線初選噴嘴、喉管和設備型號； 7. 校核汽蝕、材質、接口、安裝空間和維護條件； 8. 計算配套動力設備的流量、揚程、功率和調節範圍； 9. 調試時實測進口壓力、動力流量、吸入量和出口壓力。 GW 系列的型號範圍、吸氣/吸液參數、接口尺寸和選型數據表，可繼續參閱本站的《GW系列射流器選型指南》。 九、常見運行問題與檢查方法 現象 常見原因 建議檢查 不吸氣或不吸液 動力壓力不足、背壓過高、吸入管堵塞或漏氣 測量三個接口壓力，檢查閥位和氣密性 吸入量低 動力流量偏小、噴嘴磨損、吸入阻力大 核對工作點，檢查噴嘴與吸入管 噪聲或振動增大 汽蝕、兩相流不穩定、支架鬆動 核對絕對壓力與汽蝕裕量，檢查固定件 出口壓力不足 擴散段受損、工況偏離設計點、下游阻力變化 檢查內部結構並重新計算系統阻力 性能逐步下降 結垢、沉積、堵塞或腐蝕 制定沖洗和定期檢查計劃 十、常見問題（FAQ） 1. 噴射泵需要電機嗎？ 工業噴射泵本體通常不需要電機，但必須由外部設備提供具有壓力的動力流體。若將循環泵計算在完整系統內，系統仍然需要能量輸入。 2. 噴射泵和文丘里管是一回事嗎？ 不是完全相同。兩者都涉及流道收縮導致的加速和降壓，但完整噴射泵還包含獨立吸入口、吸入室、混合喉管和擴散段，並利用動量交換持續捲吸第二股流體。 3. 噴射泵能吸氣也能吸液嗎？ 可以，但氣體和液體的密度、可壓縮性及流動特徵不同，必須使用對應的性能數據和結構，不能把吸空氣參數直接當作吸液參數。 4. 噴射泵是自吸泵嗎？ 噴射泵可以利用射流產生吸入能力，但"自吸"是否成立取決於系統結構、初始充液、密封性和安裝條件。工業引射器與市場上帶儲壓罐的自吸井用泵不是同一類整機。 5. 噴射泵的效率高嗎？ 它的優勢主要是可靠、無運動部件並能同時完成抽吸與混合，而不是在所有工況下都具有最高泵送效率。應比較整個系統的動力消耗、傳質效果、維護成本和運行可靠性。 6. 為什麼出口背壓如此重要？ 噴射泵在擴散段只能恢復部分壓力。出口背壓過高會壓縮可用壓差，導致吸入量下降，嚴重時會停止引射。 十一、結論 噴射泵的核心不是旋轉機械，而是噴嘴加速、低壓捲吸、喉管混合和擴散增壓四個連續過程。動力流體把能量和動量傳遞給被吸流體，使設備在沒有內部運動部件的情況下完成抽吸、混合和輸送。 對於水處理和工業混合項目，可靠選型必須同時建立動力入口、吸入口和出口三個壓力邊界，並結合流量、介質、噴嘴—喉管結構、汽蝕和材質綜合判斷。只按管徑或"最大吸氣量"選擇噴射泵，往往無法得到穩定工作點。 公司資訊 公司網站：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城路一段191號 返回目錄 --- ### 噴射曝氣器詳解—運作原理、特性及應用 | 成都綠水科技 -

Description: 噴射曝氣器利用文丘里引射與高速射流強化氣液傳質。本文詳解其工作原理、結構特徵、氧利用率優勢及在市政污水、工業廢水、純氧曝氣、臭氧投加等場景的應用。 噴射曝氣器到底是什麼？一篇講清原理、優勢、場景 很多人第一次聽到「噴射曝氣器」這個詞，第一個反應往往是：它和普通曝氣到底有什麼不同？ 其實你可以把它理解成一種更擅長「吸氣、混合、攪拌、傳氧」的曝氣方式。它不是簡單地往水裡打氣，而是藉助高速水流把空氣、純氧甚至臭氧吸進來，再透過噴射和循環，讓氣體更充分地進入水體。 說得更直白一點，射流曝氣器真正厲害的地方，不只是會曝氣，而是它能把吸氣、混合、循環和傳質這幾件事一起做掉。 一、噴射曝氣器是怎麼運作的 如果把它的工作過程拆開來看，基本上可以分成兩步。 第一步，是先把水「噴快」。 動力水在水泵作用下經由噴嘴高速噴出，壓力能變成速度能，這時候射流器內部就會形成負壓區。空氣或氧氣會被這個負壓「吸」進去，然後和高速液流在射流器內部先完成一次混合，形成比較細、比較均勻的氣泡。 第二步，是把已經混好的水氣混合流送到池底再噴出去。 這時候噴流不只是自己往前衝，它還會把周圍更多的水一起帶動起來，形成明顯的循環、攪拌和捲吸作用。這樣一來，氧氣和污水、污泥接觸得更充分，氧的傳遞效率也更高。 所以，噴射曝氣器的核心邏輯不是“冒泡”，而是“高速引射 + 強制混合 + 二次噴射 + 循環傳質”。這也是它和許多傳統曝氣方式最大的差別。 结构图： 二、為什麼它比傳統曝氣更有魅力? a. 傳氧效率通常更高 氣泡越細、分佈越均勻，氧氣越容易進入水裡。 現有資料中提到，自吸式和鼓風加壓式射流曝氣在合適工況下，氧利用率可以做到 30% 到 45%；純氧射流曝氣更高，可以達到 90% 以上；而在臭氧應用測試中，臭氧利用率甚至可以做到 99% 以上。 對污水處理專案來說，這一點很關鍵。因為供氧效率上去了，系統運作就更從容，處理效果也更容易穩定下來。 b. 不只是曝氣，還能把混合和循環一起做好 很多污水池的問題，不只是氧不夠，而是混合不均勻、局部有死角、污泥懸浮不好。 噴射曝氣器因為有明顯的噴射和捲吸能力，往往能把攪拌、循環、增氧這幾件事一起做掉。對於氧化溝、推流池、混合池、氧化塘這類池型來說，這種能力很實用。 c. 系統相對簡單，改造也更靈活 以資料裡的 GWQ/B 射流曝氣器為例，系統主要由水泵、文丘里射流器、增效噴嘴和必要管道組成，整體結構比較緊湊。 如果是鼓風加壓型方案，也可以結合原廠的鼓風機或壓縮機系統來做升級改造。換句話說，不少專案並不需要把整套系統全部推倒重來，而是可以在原有基礎上提升效能。 4. 維護相對更省事 傳統曝氣頭用久了，比較容易遇到堵塞、老化、開裂這些問題，很多時候還得停水、放水之後才能檢修。 而現有資料裡多次提到，射流曝氣方案更適合不停水、不放水改造，維護重點更集中在水泵等設備上。對許多老舊污水廠來說，這點很有現實意義，因為它直接關係到檢修難度、停機時間和維運成本。 5. 噪音更低，對工況變化也更友善 資料中提到，部分安裝方式下，射流曝氣系統的噪音比較低，有些甚至可以接近靜音。 同時，它還能根據負荷變化去切換空氣、風機氣源或純氧氣源，也能透過變頻調節來適配不同工況。所以面對水量、水質波動的時候，系統的適應性通常會更強。 6. 對製程運作還有一些附加好處 在純氧射流曝氣資料裡也提到，這類系統可減少泡沫和臭味，改善污泥沉降性，降低污泥膨脹風險，並有助於提高既有污水廠的處理能力。 尤其是在高濃度廢水、臭氧廢氣回用、純氧曝氣這類要求更高的場景裡，這些附加優勢會更明顯。 三、噴射曝氣器一般用在哪些地方? 從這次整理到的資料來看，噴射曝氣器的應用範圍其實挺寬，不只是傳統意義上的污水池曝氣。 1. 市政污水和工業廢水處理 這是最常見、也是最核心的應用方向。 現有案例和資料涵蓋了生活污水、製藥廢水、垃圾滲濾液、印染廢水、食品廢水、造紙廢水、焦化廢水、酒精廢水和化學廢水等多種類型。凡是需要提高供氧效率、改善池內混合效果、減少改造停機時間的項目，都很適合重點考慮 2. 純氧曝氣和高負荷強化處理 如果專案本身負荷高、處理指標緊、池容又有限，那麼純氧射流曝氣就會特別有價值。 它能把純氧更有效率地打進水里，比較適合打標改造、擴容升級，以及高濃度有機廢水處理這類場景。 3. 臭氧投加與臭氧廢氣回收 這次資料里和臭氧相關的內容非常多，既有設計指南，也有大量工程業績。 這說明射流器在臭氧投加、臭氧廢氣回收、強化氧化這些場景裡，已經有比較成熟的應用基礎。對於深度處理項目來說，這類能力很有吸引力。 4. 河道復氧、除鐵除錳及供水預處理 除了污水廠，噴射器也可以用在河道湖泊復氧、地下水除鐵除錳、供水系統充氧等方向。 因為它的本質是強化氣液混合和傳質，所以只要場景裡對「把氣體更有效率地送進液體」有需求，它就有發揮空間。 5. 氣浮、加藥、抽真空和工業混合 雖然這些不全是嚴格意義上的“曝氣”，但底層邏輯是一樣的，都是利用射流器的引射和混合能力。 工程業績裡還能看到它被用於氣浮加氣、液氣射流真空泵、藥劑投加、罐體循環攪拌、粉體和氣體輸送等工業用途。也就是說，它本質上不只是一個曝氣設備，更像是一種流體混合平台。 工程範例圖： 四、怎么理解它真正的工程价值 如果從工程角度看，射流曝氣器真正有價值的地方，不只是某一個參數更高一點，而是它把供氧、混合、循環、攪拌這些原本分散的功能，盡量整合進了一套流體系統裡。 這樣做的好處很直接： 1. 系統更緊湊 2. 改造思維更有彈性 3. 混合和傳氧更容易兼顧 4. 維運壓力相對較小 尤其是對老舊污水站來說，如果原來的曝氣頭已經衰減，風量也不夠，池內供氧還不均勻，那麼射流曝氣往往不是單純「換個設備」這麼簡單，而更像是一條提效和改造路線。 五、總結 簡單總結，射流曝氣器是一種以文丘里引射和二次射流強化傳質為核心的高效曝氣技術。 它真正的優勢，不只是增氧快，而是能夠同步完成吸氣、混合、循環和攪拌。所以在市政污水、工業廢水、純氧曝氣、臭氧投加、河道復氧等場景裡，它都有強烈的適應性。 如果一個專案正面臨提標、擴容、降噪、減少檢修、提升氧利用率這些需求，那麼射流曝氣器確實是一條很值得認真評估的技術路線。 六、聯絡方式 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城一段路191號 返回目錄 --- ### 噴射曝氣器選型設計服務｜優化投資與運作成本 -

Description: 成都綠水科技提供噴射曝氣選型與設計服務，綜合考慮工作壓力、水深、數量、吸氣壓力、海拔、氣液比及水質條件。 射流曝氣選型的影響因素 在需氧量確定的條件下，射流器的選型是一個平衡投資成本與運行成本的優化過程，成都綠水科技有限公司可為客戶提供射流器選型、佈置方面的設計服務，以達到投資和運行成本優化配置的目的，綜合降低污水處理成本。 在具體的選型過程中，我們考慮的因素主要有以下幾個面向: 1. 射流器的工作壓力 : 通過水流量越大，射流器的工作壓力越大，吸入的氣量就越多。在特定充氧量需求條件下，所需的噴射器數量較少，設備購買成本較低，但由於壓力增加，水泵功率增加，動力效率降低，運作成本會增加。 2. 工作水深 : 射流器可適用於任何水深，水深增加時氧轉移效率和動力效率都提高，水系功率可以降低，運行成本下降，如圖二所示。但水深增加會使基建成本增加。 3. 射流器的數量 : 增加噴射器的數量，可以使所需的配套功率降低，投資會增加，但運作成本會下降。 4. 吸氣壓力與海拔: : 射流器的吸氣量在一個大氣壓力的條件下決定。吸氣壓力低於一個大氣壓力時依修正係數=(真空壓力/1個大氣壓力)進行修正。吸氣壓力高於一個大氣壓力時按修正係數=[(表壓+1個大氣壓力)/1個大氣壓力]”進行修正。 5. 氣液比 : 氣液比越大，單位水量吸入的氣體越多，動力效率提高但氧轉移效率會下降，但氣液比達到60%~80%以後，動力效率增加緩慢。原因在於氣泡直徑和在水中分佈狀態是氣液比越小越好。 因此，在純氧曝氣時，不主張單純追求動力效率來提高氣液比，而是要有一個最優平衡點，來兼顧氧氣利用率和氧氣傳遞功耗。 除以上因素外，水溫、鹽度、操作溶氧濃度、水的化學性質都會對射流器的型號、數量及配套功率選擇產生重要影響。 公司資訊 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城一段路191號 返回目錄 --- ### 噴射曝氣器用於屠宰廢水處理_充氧效率高_運轉穩定 -

Description: 介紹混流式水輪機尾水管渦帶補氣原理、強迫補氣射流泵工作方式及效果因素，以及壓縮空氣管網串聯射流泵節能方案。 射流泵補氣 尾水管渦帶與補氣需求 混流式水輪機在部分負荷工況下運作時，尾水管往往會出現渦帶。這種空腔渦帶在尾水管內做週期性運動，會產生強烈的壓力脈動和功率擺動。向尾水管補入一定的空氣量，是破壞尾水管中心渦帶、消除壓力脈動的較好措施。 自然補氣與強迫補氣 根據水力發電廠運作經驗，當水輪機安裝在尾水位以下深度超過 3～4 m 時，由於尾水管內壁靜壓加大，自然補氣便發生困難，這時必須依靠射流泵或空壓機等設備進行強迫補氣。 補氣射流泵工作原理 補氣射流泵的工作液體引自蝸殼的高壓力水，利用噴嘴射流吸入一定量的自由空氣；水與氣混合後呈射流狀態，向尾水管內的渦帶區補給。 補氣效果的影響因素 補氣效果與射流泵的吸氣量、泵的出口壓力、以及出口端伸入尾水管內的徑向距離有關。當射流泵吸氣量小於最優補氣量時，尾水管內的脈動壓力非但沒有減少，反而增加。 若射流泵出口壓力偏小，或伸入管內距離不夠，則補不進空氣，而且有時還會出現強烈的噪音。烏江渡水電站運作初期對射流泵補氣做了試驗，曾遇到類似問題。 設計注意事項 因此，設計補氣射流泵時，應重視吸氣量、出口壓力與伸入距離等關鍵參數，避免補氣不足或參數不匹配導致脈動加劇、噪音增加等問題。 壓縮空氣補氣與射流泵串聯方案 由水輪機導水葉後向轉輪區補入壓縮空氣，實務證明是效果較好的補氣方法。過去認為壓縮空氣耗量大而應用不廣；實際上，消除混流式水輪機不穩定工況所需的空氣量約為水輪機額定流量（m³/s）的 5%（已換算為大氣壓力），空氣壓力為水輪機工作水頭的 0.5 倍。 如果在壓縮空氣管網中串聯射流泵，以壓縮空氣為射流泵的工作流體，使其吸入一定量的自由空氣，不僅能提高補氣效果，而且可使電力消耗減少 1/2～1/3。 結語 射流泵補氣是破壞尾水管渦帶、抑制壓力脈動的有效手段。實際工程應結合電站水頭、尾水管佈置及最優補氣量需求，對射流泵吸氣量、出口壓力與伸入距離進行專項設計；必要時可採用壓縮空氣與射流泵串聯的方案，以兼顧補氣效果與運行經濟性。 返回目錄 --- ### 射流泵如何灌泵？Jet Pump引水啟動步驟 -

Source: Traditional-Chinese/how-to-prime-a-jet-pump.html - Description: 簡單介紹井用射流泵如何灌泵，包括停電檢查、加水排氣、啟動觀察、重複補水及無法引水的常見原因。 射流泵如何灌泵？ 簡單回答：給井用射流泵灌泵，就是在啟動前通過泵體上的灌水口，把泵殼和吸水管盡量充滿清水並排出空氣。關閉灌水口後短時間啟動，觀察壓力和出水情況；如果沒有建立穩定水流，應立即停機、再次補水和排氣，不能讓水泵長時間乾轉。 注意：本文所說的灌泵適用於帶電機、葉輪和噴射組件的淺井或深井射流泵。工業射流器或引射器本體沒有葉輪，通常依靠外部動力流體工作，不採用相同的灌泵方法。 灌泵前需要準備什麼？ 與水泵系統相容的清水； 漏斗或乾淨的加水軟管； 用於拆裝灌水塞的扳手； 水泵製造商說明書； 必要的手套和護目鏡。 開始前應確認吸水管、接頭、止回閥或底閥已經安裝好。吸水側漏氣或止回閥失效時，即使反覆加水，水泵也可能無法完成引水。 射流泵灌泵步驟 1. 切斷電源 關閉水泵電源並確認設備不會意外啟動。不要在電機通電時拆卸灌水塞或檢查泵體。 2. 釋放系統壓力 打開附近的水龍頭或排水閥，釋放管路中的殘餘壓力。確認壓力表回落後再操作灌水口。 3. 打開灌水口 找到泵殼上方的灌水塞或灌水口，緩慢拆下。不同型號的位置可能不同，應優先查看製造商說明書。 4. 緩慢加入清水 通過灌水口緩慢加水，讓水進入泵殼和吸水管。等待氣泡排出，並繼續加水，直到灌水口附近的水位不再明顯下降。 深井射流泵或較長吸水管可能需要多次補水。不要使用含泥沙、雜物或腐蝕性物質的水進行灌泵。 5. 裝回灌水塞 確認泵體已經充滿水後，重新安裝並鎖緊灌水塞。密封應可靠，但不要過度用力損壞螺紋或密封件。 6. 短時間啟動水泵 恢復電源並啟動水泵，觀察壓力表和出水口。正常情況下，水泵會逐漸建立壓力，並形成連續、穩定的水流。 7. 沒有出水時立即停機 如果短時間內仍未出水、壓力沒有上升，或者水泵發出異常聲音，應立即停機。待設備安全後重新打開灌水口，再次補水和排氣。 不要讓沒有水的射流泵持續運轉。乾轉可能損壞機械密封、葉輪和其他部件。允許的試運行時間應以設備說明書為準。 為什麼射流泵灌泵後仍然不上水？ 常見原因包括： 1. 吸水管漏氣：接頭、密封帶、管道或泵殼存在漏點； 2. 底閥或止回閥失效：停機後水倒流回井內，泵體無法保持充水； 3. 水位過低：實際吸程超過射流泵的工作範圍； 4. 吸水管堵塞：濾網、底閥或管路被泥沙和雜物堵塞； 5. 灌水不充分：泵殼或吸水管內仍有大量空氣； 6. 壓力開關或閥門設置不正確：出口閥門關閉或控制系統未正常工作； 7. 噴嘴或文丘里組件堵塞：結垢、泥沙或異物影響射流抽吸； 8. 葉輪或機械密封損壞：水泵無法建立所需壓力或持續吸入空氣。 如果反覆灌水仍無法建立水流，應停止嘗試，並檢查吸水側氣密性、底閥、井內水位及噴射組件。無法確認原因時，應聯繫水泵維修人員。 常見問題 射流泵每次啟動前都要灌泵嗎？ 正常密封且止回閥工作良好的系統，首次啟動或維修排空後通常需要灌泵，日常啟動不應每次重新加水。如果水泵頻繁失去引水，應檢查漏氣或水倒流問題。 可以讓射流泵空轉來自動吸水嗎？ 不建議。大多數井用射流泵需要先充水，長時間乾轉可能使機械密封過熱並損壞水泵。 灌泵需要加多少水？ 沒有統一容量。應把泵殼和吸水管盡量充滿，直到灌水口水位穩定。長管路或深井系統通常需要更多水和多次補充。 工業射流器需要這樣灌泵嗎？ 通常不需要。工業射流器本體沒有葉輪，它依靠外部水泵或其他壓力源提供動力流體。啟動時應先確認動力流體已經建立規定流量和壓力，並按系統操作規程排氣、開閥和調試。 結論 射流泵灌泵的關鍵是：先斷電，向泵殼和吸水管加滿清水，充分排出空氣，密封灌水口後再短時間啟動觀察。如果無法建立穩定水流，應立即停機檢查，避免水泵乾轉。 不同品牌和型號的結構、閥門位置及允許試運行時間不同，實際操作應始終以設備製造商說明書為準。 公司資訊 公司網站：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城路一段191號 返回目錄 --- ### 射流泵用於機組調相壓水-成都綠水科技有限公司 -

Description: 文丘里射流器安裝方式、安裝注意事項、啟動停機要點及相關技術資料說明，涵蓋管路佈置、故障排查與運行維護建議。 射流器安裝指南 成都綠水科技有限公司 一、概述 文丘里射流器是一種高效能射流裝置。帶壓工作（動力）流體從噴射器入口進入噴射腔形成高速噴射流體，高速流體產生壓力降使待加入物質（液/氣）從吸入口吸入並進入工作流體，混合液經擴散段到達出口，流速減慢、壓力回升（但低於進口壓力）。進出口之間只要有很小的壓力差即可形成負壓吸入液體或氣體。 噴射曝氣系統架構包括噴射器、增效噴嘴（二次噴射器）、循環水泵等，具備適合各種水深、免維修、安裝施工方便、可不放水施工改造等特性。同一套設備可使用空氣、風扇加壓空氣或純氧等不同氣源，以滿足處理負荷波動。 二、安裝方式 2.1 池外式安裝 池外式安裝依水泵主要分為管路幫浦、立式幫浦和自吸泵乾式安裝方式。適用於新建、改建的地上式曝氣池和地下式曝氣池結構，安裝十分快速方便，管道簡單。僅需對水泵進行維護，射流器和增效噴嘴長期運轉不需維修。 圖a：臥式幫浦乾式安裝 圖b：自吸幫浦乾式安裝 圖c：鼓風加壓式安裝 圖a 臥式幫浦乾式安裝示意 圖b 自吸幫浦乾式安裝示意 圖c 鼓風加壓式安裝示意 2.2 管道式安裝 若管道上的動力水量和壓力在所選射流器的工作範圍下，射流器可直接安裝在主管道上；在動力流量和壓力不變時，射流器吸入恆定量的氣體或液體。 若主管道上的動力流量大於所選射流器的工作流量時，則可將射流器安裝在旁通上，透過主管流量調節閥對經射流器的流量、壓力進行調節，從而對吸氣量或液量進行調節。 圖e 主管式安裝 圖f 旁路式安裝 2.3 GWQ/B射流曝氣器安裝形式 GWQ/B射流曝氣器主要由水泵、文丘里射流器、增效噴嘴及二次射流導流筒（備選）組成。系統簡單，無需鼓風機、複雜管道等設備；結構緊湊，安裝方便，維護時僅需維修水泵，維修一台設備不需要停止其他設備的運作。 GWQ：潛水射流曝氣器，可採用吊裝方式入池； GWB：噴射曝氣池外乾式安裝。 GWQ潛水噴射曝氣器吊裝 GWB噴射曝氣池外乾式安裝 2.4 GW一體化射流曝氣機組 GW射流整合設備是用液體作工作介質，利用文丘里原理，在液體高速噴射時產生負壓，使水泵吸入的混合液（污水+污泥）在射流器內與空氣/氧氣進行射流混合形成超飽和氧混合液的集裝設備。體積小、結構緊湊可移動，適用於各種改造或新建曝氣充氧場合，也可用於不停水、不放水改造工程。 GW一體化噴流曝氣機組安裝示意 三、自吸高度與吸氣口佈置 自吸射流曝氣射流器安裝在池外時，射流器吸氣口高度應高於水面。 如果射流器安裝在池內，或安裝在池外但吸氣口高度低於水面，則需要將射流器吸氣口延長至水面以上。 四、增效噴嘴在曝氣池內的佈置 增效噴嘴噴射方向的服務距離一般為5 m～6 m。選型時先依機組配置表確定噴嘴規格與數量，再依池型佈置篩選。 4.1 池寬≤6 m 在池寬方向佈置一排增效噴嘴即可滿足噴射方向的服務距離；池長方向依各型號允許的噴嘴間距佈置（例如N70間距≤3.5 m，N70B/N70C/N60間距≤3 m，N40/N30間距≤2.5 m）。 4.2 池寬＞6 m 在池寬方向需佈置多排增效噴嘴，排數可依 N＝池寬/5 m（取整）估算；噴嘴數量依排數分配後，再校核池長方向間距是否符合要求。 五、安裝後的啟動與停機要點 正確安裝完成後，須依正確閥門狀態啟停，尤其鼓風加壓方式，防止水泵泵體進氣或風扇/風管進水。 5.1 自吸射流曝氣 啟動：按水泵說明書開啟水泵，確認正向運轉；潛水泵可測自吸氣口風速​​，池外泵可觀察電機轉向；吸氣口吸氣明顯則運轉正常。 停機：按水泵說明書關停水泵即可。 5.2 鼓風加壓噴射曝氣 設備安裝後初始狀態：水泵浦、風扇停機；鼓風進氣閥FI關閉；自吸旁通閥SI全開；鼓風機放空閥FV開啟。 1. 使用鼓風加壓模式逐台啟動水泵時，未啟動水泵所附噴射器的自吸旁通閥必須開啟。 2. 禁止不開啟噴射幫浦而單獨使用鼓風機透過噴射器曝氣。 3. 確認自吸工作正常後，再開啟鼓風進氣閥FI與鼓風機，關閉自吸旁通閥SI，逐步關閉放空閥FV。 4. 停機：系統停機時先開啟SI排氣，再停機並關閉FI，最後停水幫浦；不可在風機運轉且FI開啟時停水幫浦。 5. 鼓風機停機時，未停機/未啟動水泵對應噴射器均應關閉FI並開啟SI，防止虹吸使池水進入鼓風管。 閥門開閉參考表 情況 FO FV FI SI PI PO 水泵停 / 風扇停 閉 開 閉 開 閉 閉 水泵開 / 風扇停 閉 開 閉 開 開 開 水泵開 / 風扇開 開 閉 開 閉 開 開 水泵停 / 風扇開（故障） 開 閉 閉 開 閉 閉 FO鼓風機出口閥；FV放空閥；FI鼓風進氣閥；SI自吸旁通閥；PI/PO水泵進/出口閥。 5.3 射流加臭氧 設備安裝後，水泵停機，臭氧進氣閥關閉。啟動水泵並確認自吸正常後，關閉自吸空氣閥，再開啟臭氧進氣閥。停止時先關閉臭氧進氣閥，再依說明書關閉水泵和閥門。 6.純氧/潛水設備安裝現場注意 工程實務（焦化污水純氧曝氣試驗）顯示： 1. 供氧設備、匯流排及啟動櫃就位後鋪設供氧管道，擴散器用吊車吊入污水池； 2. 為防止壓壞原有空氣曝氣管，宜在水下設置支撐平台； 3. 安裝入水時建議短暫關閉鼓風，排除水氣流湍動影響，使設備正確到位； 4. 氧氣相關設備與管道須依氧氣性質清洗脫脂處理，並符合氧氣管道安裝規範。 7.基坑降水用射流幫浦安裝（相關應用） 7.1 輕型井點 射流泵浦及配套離心泵佈置於基坑地面之上：各井點管經總管接入射流泵吸入口，離心泵採用清潔水循環。射流泵浦極限抽吸深度約10 m，通常降水深度約8 m左右。 安裝調試流程：安裝好地面離心泵、射流泵、水箱及地面管道；確定井點佈置，鑽孔後沉沒井點管並灌填砂濾料；試驗確保井點管不漏氣漏水後投入使用。 7.2 噴射井點（射流深井泵浦） 將射流泵安置於噴射井管內（一體化射流深井泵），埋深依降水深度確定；抽吸深度通常可按低於射流泵4～6 m左右考慮，一般需配套高壓水泵。 安裝調試流程：安裝地面離心泵、水箱及地面管道；確定井點佈置，鑽孔後沉沒噴射井點管並灌填砂濾料；試驗確保無漏氣漏水後投入使用。 8.與安裝相關的故障排除 射流器本身不能產生壓力差，而是依靠動力源經射流器及管道的壓損形成壓力差工作。無法正常運作時，可適當改變安裝位置以滿足壓力差要求，並建議進出口裝壓力表。 1. 進口壓力低、壓差不夠：提高水泵揚程或加壓加壓泵； 2. 配套進出連接管太小：改用與射流器進出口一致的管路； 3. 連接管道有堵塞物：清除堵塞物； 4. 吸氣管路不淨或阻塞：吹掃乾淨，清除阻塞物； 5. 長期運轉內部污垢導致尺寸變化：通常可用30%鹽酸浸泡約30分鐘清洗，再用清水沖洗。 公司資訊 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城路一段191號 返回目錄 --- ### 射流器工作原理 -

Description: 介紹水力發電廠機組技術供水射流泵的工作原理、效率、適用水頭、噪音控制、固定噴嘴限制及針閥調節式特點。 水力發電廠機組技術供水射流泵 工作原理與效率 機組技術供水射流泵以蝸殼或壩前水庫的高壓水作為工作水，吸取電站下游河水，並將通過射流泵的水流全部用於機組技術供水。由於工作水和被吸水均有效利用，供水射流泵的最高效率可達 62%～65%。 射流泵效率與面積比有密切關係。通常面積比較小時效率較高；當面積比為 4～5 時，工作效率一般可達 45%～55%。 供水安全與適用範圍 採用射流泵供水的突出優點，是機組冷卻水不易中斷，從而能保障機組安全運作。在 80～150 m 水頭段的大中型水力發電廠機組技術供水系統中，以射流泵取代常規水泵或自流減壓供水，不僅節能效果明顯，而且運作安全可靠。 高水頭工況下的噪音控制 當射流泵用於 200 m 以上水頭的水力發電廠技術供水系統時，運轉噪音通常偏高。模型試驗表明，當射流泵噴嘴入口工作水頭為 200～250 m 時，實測噪音約為 101～104 dB。因此，高水頭電站採用射流泵供水時，應採取隔音措施，以滿足人體工學要求。 模型試驗還表明，在射流泵外覆蓋約 20 cm 厚的沙土，可使運行噪音降低約 10 dB，為工程隔音設計提供了可參考的技術方案。 固定式射流泵系列試驗 根據「射流泵在中高水頭大中型水力發電廠應用」課題要求，目前已完成 70～110 m 水頭段機組技術供水固定式射流泵的系列模型測試。試驗面積比從 2.5 至 7.0，每隔 0.5 設定一級，共完成 10 組面積比試驗，可提供設計人員相應的壓力—流量表現曲線。 在此基礎上，可進一步編製 70～150 m 水頭段固定式射流泵產品系列，為水力發電廠機組技術供水系統的設計與選型提供基礎。 水頭變化對固定式射流泵的影響 射流泵在水力發電廠機組技術供水系統中的工作條件，與其他工業應用有明顯差異。由於電站上下游水位不斷變化，射流泵的固定工作條件會被打破，其流量和壓力也會隨之改變。 當實際水頭偏離射流泵設計工況約 30～50 m 時，設備可能出現供水量不足或嚴重的汽蝕噪音。對於水頭變化範圍較大的電站，固定式噴嘴射流泵難以覆蓋全部運轉工況；若依靠頻繁更換噴嘴保持穩定運行，又會增加維護和檢修的不便。 針閥調節式射流泵 為適應水頭和負載變化，可在射流泵噴嘴內設定可移動針閥。透過調節針閥位置改變有效面積比，使射流泵能夠適應電站運轉水頭與機組負荷的變化，從而在變工況下保持穩定供水並實現節能運轉。 水電部西北勘測設計院與武漢水電學院曾合作進行針閥調節式射流泵的大量模型試驗，並取得了性能良好、噪音較低的結構型式。針閥調節式射流泵具有工作範圍廣、效率高的特點，適合水頭和負載變化較大的水力發電廠機組技術供水系統；除性能參數有所改善外，其運轉噪音也可比國外同類設備低約 5～10 dB。 技術發展方向 針閥調節式射流泵的模型試驗工作已初步完成。後續仍需透過電站實際運作累積經驗，持續提升設計質量，並進一步研究運轉噪音的形成與控制方法，使設備噪音降低到允許聲級範圍內。 結語 機組技術供水射流泵兼具節能、安全與可靠等優點。固定式射流泵適用於水頭變化較小的工況；對於水頭和負載波動較大的電站，針閥調節式射流泵能夠提供更寬的工作範圍和更穩定的供水性能。實際工程應結合水頭範圍、供水流量、壓力需求及噪音控制目標進行專案設計與選用。 返回目錄 --- ### 水力發電廠排水射流泵-成都綠水科技有限公司 -

成都綠水科技有限公司 - URL: https://cd-greenwater.com/Traditional-Chinese/how-ejector-creates-vacuum.html - Canonical: https://cd-greenwater.com/Traditional-Chinese/how-ejector-creates-vacuum.html - Language: zh-Hant - Source: Traditional-Chinese/how-ejector-creates-vacuum.html - Description: 簡單解釋引射器如何利用動力流體、噴嘴、吸入室、喉管和擴散段產生真空，並介紹影響真空度的主要因素。 引射器如何產生真空？ 引射器利用高壓動力流體通過噴嘴形成高速射流。動力流體加速後，噴嘴出口和吸入室附近的靜壓降低；當這裡的壓力低於被抽容器的壓力時，氣體便從吸入口進入引射器。被吸入的氣體與動力流體在喉管內混合，隨後經過擴散段減速並恢復部分壓力，最後一起排出。氣體持續被帶走，被抽容器內的壓力隨之下降，於是形成真空。 引射器產生真空的四個步驟 1. 動力流體進入噴嘴 具有一定壓力和流量的水、空氣或蒸汽進入引射器。動力流體可以由水泵、壓縮機或蒸汽系統提供。 2. 噴嘴把壓力轉換為速度 動力流體通過收縮噴嘴時，流通面積變小，流速迅速升高，同時靜壓下降。高速射流在吸入室形成一個低壓區域。 3. 低壓區吸入氣體 當吸入室壓力低於被抽設備或容器內的壓力時，壓差推動氣體進入吸入口。高速射流不斷捲吸並帶走這些氣體，使容器內的氣體分子逐漸減少，內部絕對壓力持續下降。 4. 混合流經過擴散段排出 動力流體和被吸氣體在喉管中交換動量並混合。混合流進入逐漸擴大的擴散段後速度降低，部分動能轉化為壓力能，使混合流能夠克服出口背壓並排出。 整個過程可以概括為： 動力流體壓力能 → 噴嘴高速射流 → 形成低壓並捲吸氣體 → 喉管混合 → 擴散段恢復壓力並排出 真空是被"吸"出來的嗎？ 嚴格來說，引射器不是直接製造一個空洞，而是利用壓力差和高速射流不斷移走容器內的氣體。當氣體被排出的速度大於外界氣體洩漏或製程氣體產生的速度時，容器內壓力就會降低，形成低於大氣壓的真空狀態。 因此，引射器能夠達到的最終真空度，取決於抽氣能力與系統漏氣量、蒸發氣量及其他氣體負荷之間的平衡。 引射器的主要結構 部件 作用 動力入口 接收高壓水、壓縮空氣或蒸汽 噴嘴 把壓力能轉換為高速射流 吸入口 連接需要抽真空的容器或管路 吸入室 形成低壓區並接收被吸氣體 喉管 讓動力流體和被吸氣體交換動量、完成混合 擴散段 降低流速、恢復部分壓力並推動混合流排出 哪些因素會影響真空度？ 1. 動力流體壓力和流量 動力壓力或流量不足時，噴嘴無法形成設計要求的高速射流，吸入室壓力就不能充分降低。 2. 噴嘴和喉管尺寸 噴嘴出口面積、喉管面積及其比例決定引射器的抽氣量、真空度和允許出口壓力。尺寸不匹配時，即使動力壓力很高，也不一定能夠獲得理想真空。 3. 出口背壓 出口管路过细、過長、堵塞或下游壓力過高，會妨礙混合流排出。背壓超過設計範圍時，抽氣量會下降，嚴重時可能失去真空。 4. 吸入管路阻力 吸入管過長、管徑過小、彎頭過多或閥門開度不足，都會增加阻力，使設備入口測得的真空與被抽容器內的實際真空不同。 5. 系統漏氣 法蘭、閥門、密封件、儀表接口或焊縫漏氣，會不斷把外界空氣帶入系統。漏氣量過大時，引射器可能始終無法達到目標真空度。 6. 氣體性質和溫度 被抽氣體的分子量、溫度、含濕量和可凝性都會影響引射性能。使用蒸汽引射器時，動力蒸汽品質和冷凝條件也非常重要。 為什麼引射器不需要運動部件？ 引射器不依靠葉輪或活塞抽氣，而是使用動力流體本身的能量完成加速、捲吸和輸送。因此，引射器本體通常沒有運動部件，具有結構簡單、維護量小、可處理潮濕或腐蝕性氣體等特點。 但是，"沒有運動部件"並不表示不消耗能量。動力水、壓縮空氣或蒸汽都需要由外部系統提供，其能耗應納入整套真空系統計算。 引射器無法建立真空怎麼辦？ 可以依次檢查： 1. 動力流體壓力和流量是否達到設計值； 2. 動力流體閥門和吸入口閥門是否正確開啟； 3. 噴嘴、喉管或出口管路是否堵塞； 4. 出口背壓是否超過允許範圍； 5. 吸入管路和被抽系統是否漏氣； 6. 真空表量程、安裝位置和讀數是否正確； 7. 實際氣體負荷是否超過引射器設計抽氣量； 8. 噴嘴是否磨損、腐蝕或結垢。 常見問題 引射器和真空泵有什麼區別？ 機械真空泵通過旋轉或往復部件排出氣體；引射器利用高速動力流體捲吸氣體。引射器結構簡單，但需要持續消耗動力流體。 引射器可以使用哪些動力流體？ 常見動力流體包括加壓水、壓縮空氣和蒸汽。應根據目標真空度、抽氣量、氣體性質、現場能源條件和材質要求選擇。 動力壓力越高，真空度一定越高嗎？ 不一定。引射器需要在設計工作點附近運行。動力壓力過低會降低性能，但盲目提高壓力也可能增加能耗，並不一定繼續提高真空度。噴嘴、喉管、氣體負荷和出口背壓必須相互匹配。 引射器能達到絕對真空嗎？ 不能。實際系統始終存在氣體負荷、洩漏、流動損失和設備性能極限。工程上應以絕對壓力或規定條件下的真空度表示目標，不能把"真空"理解為壓力等於零。 結論 引射器產生真空的核心，是讓動力流體通過噴嘴形成高速射流，在吸入室建立低壓區，並持續捲吸、混合和排出被抽氣體。能否達到目標真空度，不僅取決於動力壓力，還取決於噴嘴與喉管結構、抽氣負荷、吸入阻力、出口背壓及系統密封性。 公司資訊 公司網站：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城路一段191號 返回目錄 --- ### 增效噴嘴原理、優點及應用 | 成都綠水科技 -

Description: 公司提供多級蒸汽噴射器真空系統（含級間冷凝器），適用於VDU減壓蒸餾、凝汽器抽不凝氣及化工真空。無運動部件，耐腐蝕耐含塵，運行穩定；支持按蒸汽條件與真空度定制。 什麼是蒸氣噴射器 1. 引言 在現代工業加工中，創建和維持可靠的真空環境對於優化產品品質、降低能耗以及促進複雜的化學反應至關重要。蒸汽噴射器（通常被稱為蒸汽噴射真空幫浦或蒸汽噴射器）是一種高度專業化的固定設備，用於產生真空、壓縮氣體或輸送製程流體。 與依賴活塞、葉輪或旋轉螺桿的傳統機械真空泵不同，蒸汽噴射器利用高速蒸汽噴射來捲吸和壓縮氣體。對於工業客戶而言，這意味著該系統完全沒有內部運動部件。它是一種超可靠、重型的機械設備替代方案，特別適用於粉塵、腐蝕性蒸氣或高溫氣體會迅速損壞傳統機械的惡劣加工環境。無論是作為單一單元使用，還是配置成複雜的多層結構，蒸汽噴射器仍然是全球穩健製程工程的基石。 2. 工作原理 蒸汽噴射器的工程結構是基於熱力學和流體力學的基本原理—特別是文丘里效應和氣體動力學。整個運轉過程可分為三個不同的、連續的階段，這些階段都發生在裝置的內部幾何結構中。 第一階段：膨脹與加速（噴嘴段） 過程始於高壓動力流體（通常為過熱蒸汽或乾飽和蒸汽）進入噴射器殼體。動力流體被引導通過一個精密加工的收縮-擴張噴嘴（也稱為德拉瓦爾噴嘴）。當蒸氣通過噴嘴的喉部時，其靜壓能降低，速度增加。當蒸汽從噴嘴的擴張段進入吸入室時，它完全膨脹，加速至超音速——通常在馬赫數 2 到 5 之間。 第二階段：捲吸和動量傳遞（吸入和混合室） 蒸氣噴流的急遽加速會在吸入室內形成一個局部極低靜壓區。由於該腔室內的壓力遠低於所連接的製程容器的壓力，製程氣體、蒸氣或空氣會被自然地吸入噴射器本體。進入噴射器本體後，製程氣體與超音速蒸氣噴射相遇。在混合段，發生高速動量傳遞：高速運動的蒸氣捲吸速度較慢的製程分子，從而形成均勻的蒸氣和製程氣體混合物。 第三階段：壓縮與減速（擴散器段） 混合流體隨後進入擴散器，該擴散器具有收縮的入口、狹窄的喉部和擴張的出口。當混合物流經擴散器擴張的擴張型腔體時，其速度強制降低。根據伯努利原理和能量守恆定律，這種減速迫使超音速流體的動能轉換為靜壓能。因此，混合物被壓縮到遠高於吸入室壓力的排出壓力，從而可以將其排放到冷凝器、後續的噴射器級或直接排放到大氣中。 3. 蒸氣噴射器的主要優點 在比較真空技術時，工程團隊經常選擇蒸汽噴射器而不是液環泵、乾式螺桿泵或旋轉葉片系統，因為蒸汽噴射器具有一系列明顯的運行和經濟優勢。 1. 無內部運動部件：由於本裝置完全依賴流體動力學而非機械運動，因此無需潤滑、磨損或更換軸承、齒輪、活塞或密封件。這直接轉化為前所未有的機械可靠性和超長的檢修間隔。 2. 對惡劣製程流體具有極高的耐受性：機械幫浦難以應付夾帶現象。蒸汽噴射器可以輕鬆處理濕蒸汽混合物、腐蝕性化學氣體、磨蝕性顆粒物和爆炸性蒸汽，而不會發生災難性的機械故障。 3. 低資本投入和經濟的規模化：蒸汽噴射器的初始資本成本遠低於同等容積容量的機械泵。對於深真空條件下的大流量應用，蒸汽噴射器是市場上性價比最高的選擇。 4. 防爆且安全運行：由於蒸汽噴射器無需電氣連接或摩擦產生部件即可在製程流程中運行，因此無需昂貴的防爆外殼，即可在危險環境（例如 ATEX 0 區或 1 區）中安全運行。 5. 安裝靈活緊湊：噴射器重量輕、佔地面積小。它們可以水平、垂直或傾斜安裝，並且通常直接懸掛在管道系統上，從而最大限度地降低結構支撐成本並節省寶貴的地面空間。 4. 主要應用領域： 蒸氣噴射器是一種用途廣泛的裝置，廣泛應用於全球眾多產業： 煉油與石油化學： 在煉油領域，原油真空蒸餾裝置 (VDU) 或許是最突出的應用。為了在不引起熱裂解的情況下分離重質烴，必須在低至 10 至 30 毫巴的壓力下蒸餾重質常壓殘渣。多級蒸汽噴射器系統與中間冷凝器結合，能夠持續處理這些重質、腐蝕性和高溫烴類負荷。 發電： 在火力發電廠、核電廠和聯合循環發電廠中，蒸汽渦輪機的廢氣排入表面冷凝器以優化熱效率。保持冷凝器內部的深度真空至關重要。蒸汽噴射器用作抽氣和保壓系統：在啟動階段（抽氣），它們快速排出冷凝器中的空氣；在正常運作階段（保壓），它們持續去除洩漏到系統中的不凝性氣體，從而保持渦輪機的最佳性能。 化學和製藥加工： 許多化學合成、聚合反應和藥物成分提取都需要溫和的低溫煮沸或乾燥，以防止產品降解。蒸汽噴射器可提供工業蒸發器、結晶釜、真空乾燥器和脫臭裝置（常見於食用油加工）所需的穩定真空。 冶金工業： 在現代煉鋼中，真空脫氣 (VD) 和真空氧脫碳 (VOD) 等技術用於生產高純度低碳鋼。這些製程會釋放大量高溫、含塵的一氧化碳和氫氣。蒸氣噴射器能夠輕鬆應對這些惡劣的含塵氣流，在幾分鐘內即可排出大量冶金鋼包中的氣體。 5. 工業案例研究 案例研究1：消除煉油廠真空蒸餾裝置停機時間 背景：北美一家中型煉油廠的真空蒸餾裝置採用機械式乾式螺桿真空幫浦系統。製程氣體中含有高腐蝕性硫化物和磨蝕性催化劑細粉，導致轉子卡滯和泵浦每4至6個月發生一次故障。每次故障都會造成數百萬美元的生產損失和專門的維護成本。 解決方案：該煉油廠用定制設計的帶有殼管式冷凝器的三級蒸汽噴射器系統替換了原有的機械系統。 結果：蒸汽噴射器系統成功地處理了腐蝕性化合物和催化劑細粉，且性能未受影響。該煉油廠報告稱，在連續4年期間，與真空系統相關的非計畫停機時間為零，預計節省了超過320萬美元的維護和收入損失成本。此外，該煉油廠利用鄰近鍋爐裝置的現有廢蒸汽作為動力流體，使該系統具有很高的能源效率。 案例研究2：提升 500MW 火力發電廠效率 背景：某燃煤電廠因冷凝器儲氣所使用的液環真空幫浦系統老化且性能下降，導致發電效率低於最佳水準。該系統無法維持 40 mbar 的設計真空度，造成汽輪機背壓升高，進而降低了電廠的淨兆瓦輸出功率。 解決方案：工程師為電廠改造了一套現代化的雙元件兩級蒸汽噴射器排氣裝置。雙元件配置提供了 2x100% 的冗餘度，允許在不停機的情況下對其中一台機組進行維護或檢查。 結果：新噴射器投入使用後，立即將冷凝器真空度恢復最佳設計參數。修正後的汽輪機背壓使電廠整體發電效率提高了 0.8%，這意味著每年可節省大量燃料成本，並在不到 9 個月的運行時間內實現了投資回報。 6. 摘要及產業目標 蒸汽噴射器巧妙地運用流體動力學原理，解決了現代工程中一些最棘手的真空產生難題。它利用高壓驅動蒸汽壓縮和輸送氣體，無需任何移動部件，從而實現了機械替代方案無法比擬的運行時間和可靠性。 蒸汽噴射器幾乎可以部署在任何配備鍋爐系統的工廠中，但某些特定行業將其視為關鍵基礎設施：煉油廠和石化聯合企業：對於連續真空蒸餾裝置至關重要，因為設備故障會導致整條生產線停產。 發電廠：需要持續清除大型表面冷凝器中的不凝性氣體，以維持發電效率。 重冶金：對於大容量鋼包脫氣至關重要，因為高溫、磨蝕性強、含塵氣體的裝置會迅速損壞機械部件。 對於希望最大限度地延長製程正常運作時間、降低維護成本並建立能夠處理惡劣製程流程的堅固真空基礎設施的營運而言，蒸氣噴射器仍然是首選的、經過時間考驗的選擇。 公司資訊 公司網址：https://cd-greenwater.com 技術聯絡電話：028-85130135 客服聯絡電話：18515915124 聯絡信箱：jane1984@cd-greenwater.com 地址：成都市雙流區西航港長城一段路191號 返回目录 --- ## English Online Manuals ### Gas Jet Eductor | Gas-Water, Gas-Solid and Gas-Gas Data -

One of the examples is sampling in which motive gas jet through eductor nozzle and draws sampled liquid out for continuous or interval analyzing. Gas delivery: When the dry delivery is a must, It is applicable to use pressurized air or nitrogen to transport solids. Granular solids enter into the suction chamber under vacuum effect produced by gas jet, mix and move with gas through a diffuser to increase gas-solids mixture pressure. Gas and solids are separated after reaching to the reception point. Ultrasonic Gas Ejector In the so called high pressure ejectors, vacuum entrainment and momentum exchange are realized by ultrasonic jets of motive gases.

Priming of centrifugal pump with LJG eductor is one of the various uses. The volume being primed are generally small, so a small quantity of fluid (pressurized water/air)can be applied as motive flow of the eductor.GW LJG eductor is also a safe option where it is dangerous to use power driven exhaust. Maintaining pressure: Some apparatus need to keep their internal pressure within a certain extend during operation, meanwhile, there is gas produced or entrained during the process. In this case, GW LJG can be utilized to exhaust gas and keep the pressure at the expected value. The above figure shows an example which is a MBR apparatus for wastewater treatment: When pressure rises in the gas-water separator, a differential pressure signal is given to a motive flow valve which automatically opens and the LJG eductor is activated to draw gas from the separator until the pressure drops to the minus desired point.
