Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation technology for hydrogen production by electrolysis, specifically to a high-efficiency gas-liquid separation device for hydrogen production by water electrolysis that prevents water pollution. Background Technology

[0002] In the field of hydrogen production technology through water electrolysis, especially in AEM (anion exchange membrane) electrolysis hydrogen production systems, the gas-liquid separation device is a core component for ensuring product purity, preventing water pollution, and ensuring stable system operation. As the core of the electrochemical reaction, the AEM electrolyzer inevitably produces hydrogen mixed with electrolyte, forming a gas-liquid mixture. Incomplete separation not only reduces hydrogen purity, affecting subsequent use, but also causes water pollution and waste due to direct discharge or loss of electrolyte. Furthermore, the operational stability, ease of maintenance, and energy consumption of the separation device directly determine the economy and reliability of the entire hydrogen production system. Therefore, efficient, environmentally friendly, and stable gas-liquid separation technology has always been a key focus of industry research and development.

[0003] Existing gas-liquid separation devices for hydrogen production via water electrolysis are mainly designed based on single centrifugal separation, gravity sedimentation, or simple membrane filtration principles. Although they can achieve basic gas-liquid separation, an analysis of the innovative aspects of this application reveals the following significant lack of innovation: Firstly, the separation efficiency improvement mechanism is singular, and the droplet escape problem is prominent: Existing technologies mostly rely on single cyclone separation or gravity settling to achieve gas-liquid separation, without forming a synergistic separation mechanism of "centrifugal enhancement + airflow disturbance". For example, traditional cyclone separators only form a centrifugal force field through tangential inflow, without setting up a linkage disturbance structure of forward and reverse blades, which cannot form a shearing and breaking effect on the airflow in the central region, making it difficult to effectively break up the agglomeration of tiny droplets, resulting in a high droplet escape rate; Secondly, the lack of fault diagnosis and self-cleaning capabilities leads to high maintenance costs: Existing technologies can only provide preliminary warnings of abnormal separation efficiency through pressure or flow sensors. They lack a dual fault identification system of "graded detection of blockage + precise diagnosis of deformation," making it impossible to distinguish whether the fault is caused by membrane module blockage or deformation. This forces maintenance personnel to blindly disassemble and inspect, significantly increasing maintenance time. Furthermore, traditional devices lack self-cleaning functions, requiring manual disassembly, cleaning, or replacement of membrane modules after blockage. This not only results in long downtime (over 2 hours per maintenance session) but also exacerbates component wear due to frequent disassembly, leading to a high proportion of maintenance costs in the overall equipment operating costs.

[0004] Therefore, this invention proposes a high-efficiency gas-liquid separation device for hydrogen production by water electrolysis that prevents water pollution, in order to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a highly efficient gas-liquid separation device for hydrogen production via water electrolysis that prevents water pollution, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency gas-liquid separation device for preventing water pollution in water electrolysis hydrogen production, comprising: an AEM hydrogen production device and a first component installed thereon, wherein the AEM hydrogen production device includes a heat exchange component, a circulating water tank, an AEM electrolyzer, an interface panel, and a gas-liquid separation component, the AEM electrolyzer being the core of the electrochemical reaction of the device, the circulating water tank being connected to the AEM electrolyzer to provide a heat exchange medium, the heat exchange component forming a heat exchange loop with the circulating water tank and the AEM electrolyzer to regulate the operating temperature of the AEM electrolyzer, the gas-liquid separation component being connected to the AEM electrolyzer to separate the gas and liquid in the electrolysis products, and the interface panel being electrically or fluidly connected to the AEM electrolyzer, the heat exchange component, the circulating water tank, and the gas-liquid separation component respectively, for realizing external connection and control signal transmission, the first component comprising: disposed on the gas-liquid separation component The cyclone separator is composed of a cylinder and an inverted cone. The liquid outlet of the cyclone separator is connected to a circulating water tank to realize the recycling and reuse of the separated liquid. A mixture inlet is fixedly connected to the upper end of the cyclone separator. The mixture inlet is tangentially connected to the cyclone separator, and the mixed product is introduced into the cyclone separator along the tangential direction. Under the constraint of the cylinder wall, a high-speed rotating airflow is formed, which generates a strong centrifugal force field. The liquid is quickly thrown towards the cylinder wall and falls along the inverted cone after separating from the gas. It is collected by the liquid collection tank, and the discharged gas forms an upward airflow and is discharged through the gas outlet pipe. A liquid collection tank is fixedly connected to the bottom of the cyclone separator for collecting liquid. The cyclone separator is used to separate the gas-liquid mixture by using centrifugal force and density difference. A conical positioning body is fixedly connected to the lower middle part of the cyclone separator, and an outer shell is fixedly connected to the top of the conical positioning body. The first component also includes: a positioning shaft fixedly connected to the outer casing, the positioning shaft extending upward and fixedly connected to the top surface of the cyclone separator, a forward blade component rotatably connected to the upper end of the positioning shaft, the forward blade component consisting of forward rotating blades and a positive bevel gear, and a reverse blade component rotatably connected to the lower end of the positioning shaft, the reverse blade component consisting of reverse rotating blades and a reverse bevel gear, the reverse blade component being disposed in the middle of the forward rotating blades and the positive bevel gear of the forward blade component, and the bevel gears in both the forward blade component and the reverse blade component being meshed with a linkage bevel gear, the airflow formed by the mixture product entering at the mixture inlet drives the forward blade component to rotate, and the positive bevel gear in the forward blade component, through the meshing of the linkage bevel gear, transmits the rotation of the reverse bevel gear in the reverse blade component, realizing the reverse rotation of the forward blade component and the reverse blade component, thus disrupting the airflow in the cyclone separator; It also includes a second component for improving the degree of gas-liquid separation.

[0007] Preferably, the outlet of the circulating water tank is connected to the inlet of the heat exchange component, the outlet of the heat exchange component is connected to the inlet of the heat exchange medium of the AEM electrolytic cell, and the outlet of the heat exchange medium of the AEM electrolytic cell is connected to the inlet of the circulating water tank, forming a closed heat exchange loop. The heat exchange component is equipped with a temperature regulating unit for regulating the temperature of the heat exchange medium. The outlet of the mixed product after electrolysis of the AEM electrolytic cell is connected to the inlet of the mixture in the gas-liquid separation component.

[0008] Preferably, the forward-rotating blade component and the tangential mixture inlet are on the same plane. The forward-rotating blade in the forward-rotating blade component is an arc-shaped twisted blade. The twist angle causes the airflow to generate "spiral acceleration" between the blades, further enhancing the centrifugal force. The arc-shaped surface can more efficiently capture the kinetic energy of the gas-liquid mixture, improving the efficiency of driving the blade rotation. The reverse-rotating blade in the reverse-rotating blade component is an inclined blade with an outer ring sawtooth shape. The inclination angle causes the blade to form a shear angle with the airflow rotation direction, enhancing the obstruction and shearing effect on the airflow and improving the efficiency of breaking up droplet agglomerates. The sawtooth edge can "cut" the vortex, disrupt the continuity of the central vortex, and reduce droplet escape. The small gap between the sawtooths can prevent large particles of impurities from getting stuck, while facilitating the passage of airflow.

[0009] Preferably, the second component includes an exhaust pipe fixedly connected to the upper end of the cyclone separator. A connecting pipe is spirally connected to the middle of the exhaust pipe. A positioning frame is fixedly connected to the connecting pipe by bolts. A drive gear is rotatably connected to one side of the bottom of the positioning frame. A front-end ratchet is fixedly connected directly below the positioning frame. A driven gear ring is fitted and fixedly connected to the outer ring of the front-end ratchet, meshing with the drive gear. A through hole is provided in the middle of the front-end ratchet for gas flow and filtration. An inner T-groove with a T-shaped cross-section is provided on the lower surface of the front-end ratchet. Preliminary cleaning and testing of the flow rate of the third component.

[0010] Preferably, a wind speed sensor is installed inside the air outlet pipe. The wind speed sensor is connected to an external controller to detect the internal gas flow rate. The air outlet pipes connected to both ends of the connecting pipe are respectively composed of a positive cone and an inverted cone. The drive gear is driven by an external power supply.

[0011] Preferably, the third component includes a reverse-face ratchet that engages with the positive-face ratchet. The teeth on the reverse-face ratchet engage with the teeth on the positive-face ratchet in a forward rotational engagement, while the reverse rotational engagement allows for transmission. A connecting ring is fixedly connected to the side of the reverse-face ratchet closest to the positive-face ratchet. The connecting ring is slidably inserted into an inner T-groove. An auxiliary spring is fixedly connected to the side of the connecting ring furthest from the reverse-face ratchet. A locking ring is fixedly connected to the side of the auxiliary spring furthest from the connecting ring. The locking ring is rotatably connected to the inner T-groove. The locking ring, the connecting ring, and the auxiliary spring cooperate to engage in the inner T-groove, connecting the reverse-face ratchet and the positive-face ratchet. A trigger ring is fixedly connected to the inner ring of the auxiliary spring. An electromagnetic ring is fixedly connected to the inner ring of the inner T-groove. The electromagnetic ring and the trigger ring cooperate to provide feedback on the degree of blockage. It also includes a fourth component for detecting abnormal causes of wind speed changes.

[0012] Preferably, multiple auxiliary springs are arranged around the center of the ratchet on the reverse end face, and the insertion ring, auxiliary spring, and snap ring are all arranged in the inner T-groove. Three sets of electromagnetic rings are equidistantly distributed on the same vertical line.

[0013] Preferably, the fourth component includes a membrane module fixedly installed at the through hole in the middle of the ratchet on the positive end face. The membrane module is used to separate suspended solids and metal ions in the electrolyte, thereby improving the gas-liquid separation rate. The inner ring of the ratchet on the negative end face has a receiving groove. Each of the four receiving grooves has a sleeve fixedly connected to it. An electrical contact and a strain gauge are fixedly connected to the end of the receiving groove near the center of the membrane module. The electrical contact and the strain gauge are fixedly connected to the sleeve by bolts. The electrical contact and the strain gauge are on the same straight line. The strain gauge is in contact with the upper surface of the membrane module. The four electrical contacts are set in two groups, with those on the vertical line being the same group. When two electrical contacts approach each other under the extension of the sleeve, if the surface of the membrane module is not deformed, the two electrical contacts will come into contact and trigger. If the membrane module is deformed and affects the airflow, the operator will be prompted by the external controller that the membrane module needs to be replaced or repaired.

[0014] Preferably, the storage slots are arranged in four circumferentially around the center of the membrane module. The sleeve is composed of multi-stage tubing and extends towards the center end of the membrane module. The length of the extended sleeve is the same as the radius of the membrane module. An air pump and an air outlet valve are connected to the end of the sleeve away from the center of the ratchet on the positive end face. The air outlet of the air pump is connected to the inner cavity of the sleeve. A return spring is provided in the inner cavity of the sleeve.

[0015] Compared with the prior art, the present invention provides a highly efficient gas-liquid separation device for preventing water pollution in the electrolysis of water to produce hydrogen, which has the following beneficial effects: The mixed product airflow drives the forward blade component to rotate. The "spiral acceleration" effect of its arc-shaped twisted blades can further enhance the centrifugal force field strength. The arc-shaped blades improve the capture efficiency of airflow kinetic energy, ensuring stable high-speed rotation of the blades. The forward blade component drives the reverse blade component to rotate in the opposite direction through the linkage bevel gear transmission. The sawtooth inclined structure of the reverse blade forms a shear angle with the airflow, which can efficiently break up incompletely separated droplet agglomerates. The "cutting" effect of the sawtooth edge on the central vortex reduces the escape rate of small droplets, thereby improving the overall gas-liquid separation efficiency and increasing the purity of hydrogen.

[0016] When the membrane module becomes clogged due to impurities, the external controller controls the drive gear to rotate in reverse. The meshing transmission between the drive gear and the driven gear ring drives the front end ratchet to rotate. The inclined tooth structure of the front and back end ratchets, combined with the elastic reset effect of the auxiliary spring, causes the back end ratchet to generate high-frequency vibration in the vertical direction. The vibration is transmitted to the membrane module, which can efficiently shake off the solid and liquid impurities attached to the surface. In conjunction with backflushing, the flow efficiency of the membrane module is restored and improved. Initial unclogging can be completed without disassembly, shortening the maintenance time.

[0017] The wind speed sensor in the outlet pipe monitors the gas flow rate in real time, enabling preliminary fault warning; the electromagnetic ring and trigger ring in the third component can provide feedback on the blockage risk level based on changes in transmission resistance, and the three sets of equidistantly distributed electromagnetic rings can distinguish the degree of blockage; the electrical contacts and strain gauges in the fourth component can determine whether the membrane module is deformed, solving the technical problem that traditional devices can only detect faults but cannot distinguish between "blockage" and "deformation", avoiding cost waste caused by blind maintenance.

[0018] The forward blade component is directly driven by the mixed product airflow, requiring no additional power input and reducing energy consumption; the elastic buffer design of the auxiliary spring makes the transmission between the positive and negative end face ratchet more stable, reducing energy loss caused by mechanical wear; the multi-stage sleeve structure and reset spring design of the sleeve ensure that the detection action of the electrical contacts and strain gauges is activated only when the wind speed is abnormal, further reducing the standby power consumption of the equipment.

[0019] The design of forward and reverse rotation transmission of the ratchet blocks on the positive and negative ends, combined with the sliding connection of the insertion ring and the inner T-groove, and the limiting and locking structure of the auxiliary spring, the insertion ring and the inner T-groove, achieves the dual effects of stable axial connection and precise circumferential transmission, reducing transmission error. The limiting effect of the insertion ring on the auxiliary spring prevents parts from falling off during vibration, thus extending the continuous operating life of the equipment.

A mixture inlet 22 is fixedly connected to the upper end of the cyclone separator 21, and the mixture inlet 22 is tangentially connected to the cyclone separator 21. The mixed product is introduced into the cyclone separator 21 along the tangential direction, forming a high-speed rotating airflow under the constraint of the cylinder wall, thereby generating a strong centrifugal force. In the field, the liquid is quickly thrown against the cylinder wall, and after separating from the gas, it falls along the inverted conical surface and is collected by the liquid collection tank 23. The discharged gas forms an upward airflow and is discharged through the gas outlet pipe 31. The liquid collection tank 23 is fixedly connected to the bottom of the cyclone separator 21. The liquid collection tank 23 is used to collect the liquid. The cyclone separator 21 is used to separate the gas-liquid mixture by using centrifugal force and density difference.

The first component also includes: a positioning shaft 26 fixedly connected inside the outer casing 25, the positioning shaft 26 extending upward and fixedly connected to the top surface of the cyclone separator 21, a forward blade component 27 rotatably connected to the upper end of the positioning shaft 26, the forward blade component 27 being composed of forward rotating blades and a positive bevel gear, a reverse blade component 28 rotatably connected to the lower end of the positioning shaft 26, the reverse blade component 28 being composed of reverse rotating blades and a reverse bevel gear, the reverse blade component 28 being disposed in the middle of the forward rotating blades and the positive bevel gear of the forward blade component 27, and the bevel gears in both the forward blade component 27 and the reverse blade component 28 being meshed with a linkage bevel gear 29, the airflow formed by the mixture product entering at the mixture inlet 22 drives the forward blade component 27 to rotate, the positive bevel gear in the forward blade component 27 being transmitted to the reverse bevel gear in the reverse blade component 28 through the meshing of the linkage bevel gear 29, thereby realizing the reverse rotation of the forward blade component 27 and the reverse blade component 28, and disrupting the airflow inside the cyclone separator 21; It also includes a second component for improving the degree of gas-liquid separation.

[0026] The forward blade component 27 and the tangential mixture inlet 22 are on the same plane. The forward rotating blade in the forward blade component 27 is an arc-shaped twisted blade. The twist angle causes the airflow to generate "spiral acceleration" between the blades, further enhancing the centrifugal force. The arc surface can more efficiently capture the kinetic energy of the gas-liquid mixture, improving the efficiency of driving the blade rotation. The reverse rotating blade in the reverse blade component 28 is an inclined blade with an outer ring sawtooth shape. The inclination angle causes the blade to form a shear angle with the airflow rotation direction, enhancing the obstruction and shearing effect on the airflow and improving the efficiency of breaking up droplet agglomerates. The sawtooth edge can "cut" the vortex, disrupt the continuity of the central vortex, and reduce droplet escape. The small gap between the sawtooths can prevent large particles of impurities from getting stuck, while facilitating the passage of airflow.

[0027] A further embodiment: Please refer to Figures 6 to 10 As shown: The second component includes an exhaust pipe 31 fixedly connected to the upper end of the cyclone separator 21. A connecting pipe 32 is spirally connected to the middle of the exhaust pipe 31. A positioning frame 33 is fixedly connected to the connecting pipe 32 by bolts.

A driven gear ring 35 is fitted and fixedly connected to the outer ring of the front-end ratchet 36. The driven gear ring 35 meshes with the drive gear 34. A through hole is opened in the middle of the front-end ratchet 36 for gas flow and filtration. An inner T-groove 37 is opened on the lower surface of the front-end ratchet 36.

[0028] An air speed sensor is installed inside the air outlet pipe 31. The air speed sensor is connected to an external controller and is used to detect the internal gas flow rate. The air outlet pipes 31 connected to both ends of the connecting pipe 32 are composed of a positive cone and an inverted cone, respectively. The drive gear 34 is driven by an external power supply.

[0029] The third component includes a reverse end ratchet 41 that engages with the positive end ratchet 36. The toothed blocks on the reverse end ratchet 41 engage with the toothed blocks on the positive end ratchet 36 in a forward rotational engagement and in a reverse rotational drive. A plug ring 42 is fixedly connected to the side of the reverse end ratchet 41 near the positive end ratchet 36. The plug ring 42 is slidably inserted into the inner T-groove 37.

[0030] Multiple auxiliary springs 43 are arranged around the center of the ratchet 41 on the reverse end face. The insertion ring 42, auxiliary springs 43, and snap ring 44 are all arranged in the inner T-groove 37. Three sets of electromagnetic rings 45 are equidistantly distributed on the same vertical line.

[0031] The fourth component includes a membrane module 51 fixedly installed at the through hole in the middle of the ratchet 36 on the positive end face.

The inner ring of the ratchet 41 on the reverse end face has a receiving groove 52. Each of the four receiving grooves 52 is fixedly connected to a sleeve 53. An electrical contact 54 and a strain gauge 55 are fixedly connected to one end of the receiving groove 52 near the center of the membrane module 51. The electrical contact 54 and the strain gauge 55 are fixedly connected to the sleeve 53 by bolts. The electrical contact 54 and the strain gauge 55 are on the same straight line.

The sleeve 53 extends towards the center end of the membrane module 51. The length of the extended sleeve 53 is the same as the radius of the membrane module 51.

[0033] Among them, the four electrical contacts 54 are set in two groups, with those on the vertical line being the same group. When the two electrical contacts 54 approach each other under the extension of the sleeve 53, if there is no deformation on the surface of the membrane assembly 51, the two electrical contacts 54 will stick together and trigger. If the membrane assembly 51 is deformed and affects the airflow, the operator will be prompted through the external controller that the membrane assembly 51 needs to be replaced or repaired.

[0034] The working principle of all the content in the above embodiments is as follows: The following is the working process of the first component: In operation, the AEM electrolyzer 14 serves as the core of the electrochemical reaction. The hydrogen gas and electrolyte mixture generated during electrolysis are discharged through its product outlet and enter the cyclone separator 21 through the mixture inlet 22 inside the gas-liquid separation component 16. The mixture inlet 22 is tangentially connected to the cyclone separator 21, guiding the mixed product tangentially into the cyclone separator 21, which consists of a cylinder and an inverted cone. Under the constraint of the cylinder wall, a high-speed rotating airflow is formed, generating a centrifugal force field hundreds to thousands of times stronger than gravity. Based on the gas-liquid density difference, the denser electrolyte is rapidly thrown against the cylinder wall of the cyclone separator 21 and slides down the inverted cone surface to the collection tank 23 fixedly connected to the bottom for collection. The collection tank 23 is connected to the circulating water tank 13, allowing the collected electrolyte to flow back to the circulating water tank 13 for recycling and reuse, avoiding direct discharge of electrolyte and water pollution. Simultaneously, the airflow generated by the mixed product entering the cyclone separator 21 drives the forward blade component 27 in the upper section to rotate. The forward blade component 27 consists of forward rotating blades and a positive bevel gear, and is on the same plane as the mixture inlet 22. The twist angle of its arc-shaped twisted blades can generate a "spiral acceleration" effect between the blades, further enhancing the centrifugal force field strength; the arc-shaped blade surface can efficiently capture the kinetic energy of the gas-liquid mixture, improving the efficiency of driving the blade rotation; the positive bevel gear of the forward blade component 27 transmits power to the reverse blade component 28 at the lower end of the positioning shaft 26 through the meshing linkage bevel gear 29. The reverse blade component 28 consists of reverse rotating blades and a reverse bevel gear, and is located in the middle of the forward rotating blade and the positive bevel gear of the forward blade component 27. Under the transmission action of the linkage bevel gear 29 and the two bevel gears, it achieves the opposite rotation to the forward blade component 27. The outer ring of the serrated inclined blades of the reverse blade component 28 has an inclination angle that forms a shear angle with the direction of airflow rotation. This can impede and shear the airflow in the central area, effectively breaking up droplet agglomerates that have not been completely separated in the airflow. The serrated edges can "cut" the central vortex, disrupting the continuity of the vortex and reducing the probability of small droplets escaping with the airflow. At the same time, the small gap serrations can prevent large particles of impurities from getting stuck and ensure airflow passage. The conical positioning body 24 fixed in the lower middle part of the cyclone separator 21 and the outer shell 25 fixed above provide positioning support for components such as the positioning shaft 26 and the forward blade component 27. The separated liquid can flow into the collection tank 23 along the inclined surface of the conical positioning body 24, ensuring that the airflow disturbance generated by the reverse rotation acts stably on the separation process and improving the centrifugal separation efficiency. Please refer to the above work process. Figures 1 to 5 .

[0035] The following describes the working process of the second, third, and fourth components: In use, the hydrogen gas, after initial separation by the first component, forms an upward airflow along the central region of the cyclone separator 21 and enters the outlet pipe 31, which is fixedly connected to the upper end of the cyclone separator 21. A connecting pipe 32, spirally connected in the middle of the outlet pipe 31, divides it into two sections: a positive cone and an inverted cone, facilitating a smooth transition of airflow. A wind speed sensor installed inside the outlet pipe 31 is connected to an external controller to detect the hydrogen flow rate in real time and feed it back to the controller, achieving real-time monitoring of the flow rate.

[0036] Hydrogen continues to flow upwards to membrane module 51, where it further separates the liquid from the gas, causing the intercepted liquid to flow back to the collection tank 23 at the bottom of the cyclone separator 21. During long-term use, as hydrogen flows upwards, if the internal airflow becomes abnormal and slow, as detected by the wind speed sensor, it indicates that membrane module 51 is blocked or deformed, causing abnormal airflow. At this time, the external controller controls the drive gear 34 to rotate in reverse. Under the meshing transmission between the drive gear 34 and the driven gear ring 35, the driven gear ring 35 is driven to rotate in the forward direction. Since the driven gear ring 35 is fixedly connected to the positive end ratchet 36, the positive end ratchet 36 rotates in the forward direction synchronously. Under the tooth surface transmission between the positive end ratchet 36 and the negative end ratchet 41, the inclined surface of the tooth block of the positive end ratchet 36 abuts against the inclined surface of the tooth block of the negative end ratchet 41. The inclined surface causes the reverse end ratchet 41 to move downwards. With the assistance of components such as the insertion ring 42, the reverse end ratchet 41 is elastically connected to the positive end ratchet 36. The downward movement of the reverse end ratchet 41 pulls the insertion ring 42 to move vertically downwards, while the auxiliary spring 43 is stretched to store elastic potential energy. The snap ring 44 is used to help stabilize the connection between the reverse end ratchet 41 and the positive end ratchet 36 when the reverse end ratchet 41 moves downwards. When the forces of the inclined surfaces of the positive end ratchet 36 and the reverse end ratchet 41 are canceled out, the reverse end ratchet 41 moves upwards under the restoring force of the auxiliary spring 43. The elastic potential energy of the auxiliary spring 43 causes the reverse end ratchet 41 to vibrate vertically. Under the transmission of vibration, the membrane module 51 shakes off the metal ion solid and liquid impurities attached to it during this vibration process, which flow along the outlet pipe 31 into the collection tank 23, initially restoring the airflow efficiency of the membrane module 51. Furthermore, if the membrane module 51 is severely blocked, the airflow will be greatly reduced, the air pressure below the membrane module 51 will increase, and the airflow pressure will push the reverse end ratchet 41 to move upward. The insertion ring 42 will gradually insert into the inner T groove 37. At this time, the electromagnetic ring 45 on the insertion ring 42 will gradually approach the trigger ring 46 in the inner T groove 37. As the blockage becomes more severe, the electromagnetic ring 45 will gradually move deeper into the inner T groove 37, thereby triggering the trigger ring 46. There are three sets of trigger rings 46 in the vertical direction, which are connected to an external controller and represent different blockage levels. With the cooperation of the electromagnetic ring 45 and the trigger ring 46, the blockage level of the reverse end ratchet 41 will be fed back, prompting the operator to start the backflushing device to restore the flow rate of the membrane module 51. Furthermore, when the wind speed changes, the air pump connected to the sleeve 53 outputs air, causing the air pressure inside the sleeve 53 to increase. This causes the sleeve 53 to extend towards the center of the membrane assembly 51. The extension of the sleeve 53 simultaneously pushes the electrical contact 54 and the strain gauge 55 closer to the center of the membrane assembly 51. At this time, the strain gauge 55 moves against the surface of the membrane assembly 51. Because the airflow impacts the membrane assembly 51 from bottom to top, it causes the membrane assembly 51 to bulge upwards, and its surface to deform. If the surface of the membrane assembly 51 is normal, the two electrical contacts 54 will stick together and trigger, feeding back to the external controller and providing data feedback to the operator. If the membrane assembly 51 is deformed, the pressure data of the strain gauge 55 will change under the influence of the deformation of the membrane assembly 51. At the same time, the electrical contacts 54 will not stick together, and the data will be transmitted to the external controller to provide feedback on the deformation of the membrane assembly 51 and whether the membrane assembly 51 needs to be replaced. With the cooperation of the third and fourth components, the feedback indicates whether the change in wind speed is caused by blockage or deformation.
