Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and more particularly to a high-pressure high-frequency vibration membrane equipment system. Background Technology

[0002] Wastewater treatment equipment is used to treat wastewater, preventing its direct discharge and pollution of soil and water bodies. Some common wastewater treatment devices filter wastewater using static membranes. However, when treating high-turbidity wastewater, the membrane surface is easily clogged by contaminants, leading to a sharp decrease in filtration efficiency and affecting the overall treatment effectiveness. While some equipment uses centrifugal separation to separate denser impurities, contaminants can still adhere to the inner walls or key components during centrifugation, similarly affecting long-term stable operation and separation performance.

[0003] In existing technologies, a motor is used to drive the entire frame to vibrate, thereby causing the water treatment device to vibrate and remove impurities from the membrane, extending the service life of the water treatment device. However, this method only has a single vibration mode and lacks the ability to dynamically improve the antifouling ability and separation efficiency of the membrane surface by utilizing the synergistic effect of high-frequency vibration with centrifugal force field and swirling flow field. Furthermore, when using a vibrating membrane to filter wastewater, it is impossible to perform secondary separation of wastewater inside the membrane, which reduces the treatment effect of wastewater. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies that lack the synergistic effect of high-frequency vibration with centrifugal force field and swirling flow field to dynamically improve the antifouling ability and separation efficiency of membrane surface, and proposes a high-pressure high-frequency vibration membrane equipment system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The high-voltage high-frequency resonant diaphragm equipment system includes a base and also includes:

[0007] A sealed container, wherein the sealed container is connected to a mounting plate, and a plurality of elastic seats are fixedly connected between the mounting plate and the base;

[0009] An ultra-high frequency vibration membrane system includes a drive motor and an exciter mounted on the bottom of a mounting plate. A hollow tube is coaxially fixedly connected to the output end of the drive motor. The end of the hollow tube away from the drive motor passes through the mounting plate and the bottom wall of a sealed tank in sequence and is coaxially fixedly connected to multiple vibration plates. Filter membranes are mounted on the vibration plates. The vibration end of the exciter is fixedly connected to the bottom of the mounting plate and reciprocates in the vertical direction. The interiors of the multiple filter membranes are all connected to the hollow tube.

[0010] Preferably, an auxiliary frame is fixedly connected to the side of the sealed container, and the bottom of the auxiliary frame is fixedly connected to the mounting plate.

[0011] Preferably, the auxiliary frame includes multiple vertical frames fixedly connected between the sealed container and the mounting plate, and multiple ring frames fixedly connected to the multiple vertical frames. The uppermost ring frame is fixedly connected to the outside of the sealed container and has an opening for the air jet device to pass through.

[0012] Preferably, the pressurizing device includes a water inlet pipe tangentially connected to the side of the sealed tank, and a pressurizing pump is connected in series at the end of the water inlet pipe near the sealed tank, with the outlet of the pressurizing pump facing the sealed tank.

[0013] Preferably, the jetting device includes a jet pump mounted on a mounting plate. The inlet end of the jet pump is connected to an external inert gas source, and its jetting end is connected to a jet pipe. Multiple nozzles are connected to the side of the jet pipe. The ends of the multiple nozzles away from the jet pipe are tangentially connected to the side of the sealed container. The multiple nozzles are staggered with multiple vibrating plates.

[0014] Preferably, the bottom of the sealed tank is connected to a drain pipe, and a drain valve is installed on the drain pipe.

[0015] Preferably, the hollow tube is internally connected to a water pumping assembly, which includes a water pump installed on the top of the sealed tank. The water pump's pumping end is sealed through the sealed tank and communicates with the interior of the hollow tube, and its outlet end is connected to an outlet pipe.

[0016] Preferably, a fixing plate is fixedly connected to the bottom of the mounting plate, the drive motor is mounted on the fixing plate, and there are two exciters in the high-frequency vibration membrane system, which are symmetrically distributed on both sides of the drive motor.

[0017] Preferably, each of the plurality of filter membranes has a wastewater hole extending through it. The axis of the wastewater hole is parallel to the axis of the hollow tube and communicates with the interior of the sealed tank. The filter membrane has a plurality of guide grooves inside it. The guide grooves are all arc-shaped and are distributed alternately with the wastewater holes. The hollow tube has a water inlet hole that communicates with the end of the guide groove near the hollow tube. The end of the guide groove away from the hollow tube has a plurality of water outlet holes extending through it. The end of the water outlet hole away from the guide groove communicates with the interior of the sealed tank.

[0018] Preferably, the sealed container is cylindrical, with its diameter gradually decreasing from both ends to the middle.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] 1. This invention, by setting up a centrifugal system and an ultra-high frequency vibrating membrane system, utilizes the pressurizing device and jetting device in the centrifugal system to inject sewage flow and airflow in the same direction along the tangential direction of the sealed tank, forming a stable vortex. When the sewage flow forms a vortex, it generates centrifugal force, which can throw high-density pollutants toward the tank wall, creating a low-pollution zone in the center of the tank, reducing the filtration load on the membrane surface. The injection of gas in the same direction enhances the stability of the vortex, forming a gas-liquid boundary layer, and continuously cleaning the membrane surface through the air knife effect, reducing pollutant adhesion. Utilizing the drive motor and vibrator in the ultra-high frequency vibrating membrane system, the filter membrane can be simultaneously driven by vibration and rotation, thereby generating a high shear linear velocity on the membrane surface, peeling off the attached pollutants, and simultaneously forming a velocity gradient and turbulence on the membrane surface, destroying the gel layer deposited by pollutants, forming dynamic antifouling, thereby extending the filter membrane life and improving its separation performance.

[0021] 2. By setting a guide groove, the present invention can temporarily store the produced water filtered by the filter membrane. When the filter membrane rotates at high speed, the produced water is separated a second time by centrifugal force, so that the less dense clean water gathers in the hollow tube, while the more dense impurities are discharged from the water outlet, thereby further improving the purity of the produced water and improving the treatment effect of sewage.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figures 1-4 The high-voltage high-frequency vibration diaphragm equipment system includes a base 1, and also includes:

[0032] A sealed container 16 is connected to a mounting plate 3, and multiple elastic seats 2 are fixedly connected between the mounting plate 3 and the base 1.

[0033] An auxiliary frame 9 is fixedly connected to the side of the sealed container 16, and the bottom of the auxiliary frame 9 is fixedly connected to the mounting plate 3.

[0034] The auxiliary frame 9 includes multiple vertical frames fixedly connected between the sealed tank 16 and the mounting plate 3. Multiple ring frames are fixedly connected to the multiple vertical frames. The uppermost ring frame is fixedly connected to the outside of the sealed tank 16 and has an opening for the jetting device to pass through, so as to avoid interference with the jetting device.

[0035] The auxiliary frame 9 provides fixation and support for the sealed container 16, while also protecting the sealed container 16 from the outside.

[0036] The centrifugal system includes a pressurizing device and a jetting device that are tangentially connected to the side of the sealed tank 16. The pressurizing device is located above the jetting device, and the water outlet direction of the pressurizing device is consistent with the jetting direction of the jetting device.

[0037] The pressurization device includes a water inlet pipe 10 that is tangentially connected to the side of the sealed tank 16. A pressurization pump 11 is connected in series at one end of the water inlet pipe 10 near the sealed tank 16, and the outlet end of the pressurization pump 11 faces the sealed tank 16.

[0038] The booster pump 11 uses existing technology to increase the kinetic energy of the water flowing through it through mechanical drive, thereby increasing the flow rate of the water. This facilitates the high-speed injection of sewage into the sealed tank 16, where a vortex is formed to initially separate the sewage and reduce the load on subsequent sewage treatment.

[0039] The jet device includes a jet pump 8 mounted on the mounting plate 3. The air inlet of the jet pump 8 is connected to an external inert gas source, and its jet end is connected to a jet pipe 15. Multiple nozzles are connected to the side of the jet pipe 15. The ends of the multiple nozzles away from the jet pipe 15 are tangentially connected to the side of the sealed tank 16. The multiple nozzles are staggered with multiple vibrating plates 17.

[0040] The jet pump 8 uses existing technology. When it is working, it introduces a high-pressure inert gas flow into the interior of the sealed tank 16 through the jet pipe 15 and multiple nozzles. While increasing the internal pressure of the sealed tank 16, it can also maintain the stability of the swirling flow through the unidirectional flow field, thereby improving the treatment effect of sewage.

[0041] The high-frequency vibration membrane system includes a drive motor 4 and an exciter 7 installed at the bottom of the mounting plate 3. The output end of the drive motor 4 is coaxially fixedly connected to a hollow tube 6. The end of the hollow tube 6 away from the drive motor 4 is sealed and passes through the bottom wall of the mounting plate 3 and the sealed tank 16 in sequence, and is coaxially fixedly connected to multiple vibration plates 17. Filter membranes 20 are installed on the vibration plates 17. The vibration end of the exciter 7 is fixedly connected to the bottom of the mounting plate 3 and moves back and forth in the vertical direction. The interior of the multiple filter membranes 20 is connected to the hollow tube 6.

[0042] The bottom of the sealed container 16 is connected to a drain pipe 14, and a drain valve is installed on the drain pipe 14. By opening and closing the drain valve, it is easy to discharge the pollutants at the bottom of the sealed container 16 through the drain pipe 14.

[0043] The hollow tube 6 has a water pumping assembly inside, which includes a water pump 13 installed on the top of the sealed tank 16. The water pump 13 has a water pumping end that passes through the sealed tank 16 and is connected to the inside of the hollow tube 6. Its water outlet end is connected to a water outlet pipe 12.

[0044] The mounting plate 3 is fixedly connected to the bottom of the mounting plate 5. The drive motor 4 is mounted on the mounting plate 5. There are two exciters 7 in the high-frequency vibration membrane system. The two exciters 7 are symmetrically distributed on both sides of the drive motor 4, so that the vibration energy is evenly distributed in space and the vibration effect of the system is improved.

[0045] Reference Figures 5-7 Multiple filter membranes 20 are provided with wastewater holes 19. The axis of the wastewater holes 19 is parallel to the axis of the hollow tube 6 and is connected to the interior of the sealed tank 16. Multiple guide grooves 21 are provided inside the filter membranes 20. The multiple guide grooves 21 are all arc-shaped and are distributed alternately with the multiple wastewater holes 19. A water inlet hole 22 is provided on the hollow tube 6 and is connected to the end of the guide groove 21 near the hollow tube 6. Multiple water outlet holes 18 are provided at the end of the guide groove 21 away from the hollow tube 6. The end of the water outlet hole 18 away from the guide groove 21 is connected to the interior of the sealed tank 16.

[0046] The water filtered by the filter membrane 20 is centrifuged again through the guide groove 21. The resulting clean water enters the interior of the hollow tube 6 through the water inlet 22, while the impurities are discharged through the water outlet 18, thereby improving the filtration effect.

[0047] The sealed container 16 is cylindrical, with its diameter gradually narrowing from both ends to the middle. This facilitates the increase of fluid velocity at the narrowed diameter structure, thereby enhancing the scouring ability of the swirling flow on the surface of the filter membrane 20 and ensuring the continuous and stable operation of the filter membrane 20.

[0048] When using this invention, the drive motor 4 and vibrator 7 at the bottom of the mounting plate 3 are started. When the drive motor 4 is working, its output end drives multiple vibrating plates 17 to rotate through the hollow tube 6. When the vibrator 7 is working, the mounting plate 3 vibrates vertically at high frequency through the elastic seat 2, thereby driving multiple vibrating plates 17 to vibrate vertically at high frequency through the auxiliary frame 9, the hollow tube 6, and the sealed tank 16.

[0049] When treating sewage, the sewage to be treated is introduced into the sealed tank 16 through the inlet pipe 10. The pressurization pump 11 works to pressurize the sewage flowing through it. The pressurized sewage is injected tangentially into the sealed tank 16 at high speed, generating a swirling flow inside the sealed tank 16.

[0050] At the same time, the jet pump 8 is turned on, and its jet end sprays high-pressure inert gas into the sealed tank 16 through the jet pipe 15 and multiple nozzles thereon. The multiple nozzles and multiple vibrating plates 17 are staggered, and the jet direction of the nozzles is consistent with the direction of the sewage swirl. In this way, while increasing the pressure inside the sealed tank 16, it can also avoid the flow field conflict between the liquid flow and the air flow and maintain the stability of the swirl.

[0051] Under the centrifugal force of the high-speed swirling flow, the gas-liquid mixture forms an ultra-thin gas-liquid boundary layer on the inner wall of the sealed tank 16, generating ultra-high shear force to directly peel off pollutants, effectively preventing pollutants from adhering to the inner wall of the sealed tank 16. At the same time, it forms a "air knife" effect, continuously physically cleaning the membrane surface of the filter membrane 20, reducing the risk of membrane pore blockage.

[0052] When the sewage inside the sealed tank 16 flows, it enters the gap between the two vibrating plates 17 radially, and then flows tangentially along the membrane surface of the filter membrane 20. When the vibrating plates 17 vibrate vertically at high frequency, the filter membrane 20 vibrates synchronously, thereby forming a tangential shear force and velocity gradient on the membrane surface of the filter membrane 20. Small molecules (such as water) in the sewage pass through the filter membrane 20 to become product water and enter the guide tank 21, while pollutants are trapped on the membrane surface of the filter membrane 20.

[0053] When the filter membrane 20 vibrates, the vibration energy is transferred to the liquid, generating high-intensity turbulence, thereby enhancing the mass transfer efficiency, increasing the permeate flux, and disrupting the adhesion of pollutants on the membrane surface, preventing the formation of a gel layer, delaying the clogging of the membrane pores, and finally the pollutants intercepted on the filter membrane 20 fall into the bottom of the sealed tank 16 through the wastewater hole 19.

[0054] Because the vibrating plate 17 is rotating at high speed, a small amount of impurities that pass through the filter membrane 20 and are denser than water enter the guide tank 21 with the produced water. Under the action of centrifugal force, the less dense clean water approaches the hollow tube 6, while the denser impurities approach the outlet hole 18. Finally, the clean water passes through the guide tank 21, through the inlet hole 22 on the surface of the hollow tube 6, and enters the interior of the hollow tube 6. The water pump 13 works, its pumping end draws the clean water inside the hollow tube 6, and its outlet end discharges the clean water through the outlet pipe 12. The impurities that pass through the outlet hole 18 fall into the bottom of the sealed tank 16, and finally the pollutants and impurities are discharged from the bottom of the sealed tank 16 through the drain pipe 14.

[0055] The sealed tank 16 is a cylindrical shape with a narrowed middle diameter. The narrowed middle diameter structure forces the fluid to accelerate when passing through the narrow area, increasing the scouring speed and shear force of the fluid on the membrane surface, and further enhancing the antifouling effect. At the same time, the narrowed diameter structure helps to guide and maintain the vortex formed by the high-pressure water inlet on the side, making the vortex more concentrated and stable. By enhancing the local flow velocity and shear force and optimizing the vortex path, the overall antifouling ability and separation efficiency can be improved.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
