Description

An apparatus and method for producing ultrapure water based on the principle of reverse osmosis

[0001] This invention relates to the field of ultrapure water production technology, and in particular to an apparatus and method for producing ultrapure water based on the principle of reverse osmosis. Background Technology

[0002] Ultrapure water refers to water that has undergone rigorous purification treatment and contains almost no dissolved impurities or microorganisms. It has extremely high purity and is usually used in industries and experiments with very strict water quality requirements. Ultrapure water is generally produced by filtration using reverse osmosis equipment with ultra-low pore size reverse osmosis membranes.

[0003] Existing reverse osmosis equipment uses reverse osmosis filter cartridges, which are generally spiral wound membranes. During filtration, water enters and exits simultaneously from the top of the filter cartridge, resulting in the presence of both pure water and wastewater inside, which can easily lead to cross-contamination. Therefore, CN118767679A discloses a reverse osmosis filtration assembly, which includes a filter bottle, a reverse osmosis filter cartridge, and a lower end cap. A central tube is provided inside the central hole, and a baffle is provided inside the central tube. The baffle extends along the length of the central tube, dividing the central tube into a clean water channel and a wastewater channel. Several annular grooves are formed on the outer wall of the central tube, and at least one water passage hole is formed at the bottom of each annular groove. Water filtered by the reverse osmosis filter cartridge enters the clean water channel through the water passage hole, and wastewater generated by the reverse osmosis filter cartridge enters the wastewater channel through the lower end cap.

[0004] The aforementioned reverse osmosis filtration unit employs a central tube separation design, ensuring that the outflow paths of pure water and wastewater do not interfere with each other. This reduces the possibility of cross-contamination between pure water and wastewater, thus guaranteeing the filtration effect of the reverse osmosis filtration unit.

[0005] However, in practical use, the aforementioned reverse osmosis components and existing reverse osmosis equipment require continuous high pressure release at the inlet to complete the reverse osmosis of low-purity water, resulting in high energy consumption and high cost of ultrapure water preparation. At the same time, ultrapure water enters from the reverse osmosis membrane roll and exits from the outlet pipe. The number of inlet holes opened on the outlet pipe is limited, so the filtered ultrapure water cannot be discharged through the outlet pipe in a timely manner, resulting in a decrease in the ultrapure water output rate and affecting the efficiency of ultrapure water preparation.

[0006] Therefore, a new device and method for producing ultrapure water based on the principle of reverse osmosis can be adopted to overcome the shortcomings of existing technologies. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of high energy consumption and low preparation efficiency in the prior art, and to propose an apparatus and method for producing ultrapure water based on the principle of reverse osmosis.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An apparatus for producing ultrapure water based on the principle of reverse osmosis includes a reverse osmosis unit and a tubular outlet support.

[0010] The reverse osmosis unit includes an outlet cover, on which a cover is fixedly installed. A high-pressure pipe is rotatably installed inside the outlet cover. An inlet pipe is fixedly connected to the top of the high-pressure pipe. Multiple outlet holes are opened on the high-pressure pipe. A filter membrane roll is wrapped around the high-pressure pipe.

The rotating platform is equipped with multiple linkage mechanisms that cooperate with the corresponding sliding plates.

[0013] Preferably, the linkage mechanism includes a first rack fixedly mounted on a sliding plate, a second rack slidably mounted on a rotating platform, a first gear rotatably mounted on the rotating platform that meshes with both the first and second racks, a centrifugal ball fixedly mounted on the second rack, and a reset structure that cooperates with the second rack and a support structure that cooperates with the centrifugal ball mounted on the rotating platform.

[0014] Preferably, the reset structure includes a fixed plate fixedly installed on the rotating platform, and an elastic reset telescopic rod is fixedly installed on the fixed plate. The telescopic end of the elastic reset telescopic rod is fixedly connected to the second rack.

[0015] Preferably, the support structure includes a plate fixedly installed at the bottom of the rotating platform, a support telescopic rod fixedly installed on the plate, a connecting plate fixedly installed at the drive end of the support telescopic rod, the connecting plate being fixedly connected to the centrifugal ball, and a locking component cooperating with the connecting plate installed on the rotating platform.

[0016] Preferably, the locking component includes a fixed frame fixedly installed at the bottom of the rotating platform, an electromagnetic plate fixedly installed on the fixed frame, a permanent magnet plate cooperating with the electromagnetic plate fixedly installed on the connecting plate, and an energizing component cooperating with the electromagnetic plate installed on the tubular liquid outlet support.

[0017] Preferably, the energizing component includes a first conductive ring rotatably mounted on a tubular liquid outlet support, a second conductive ring fitted on the tubular liquid outlet support to cooperate with the first conductive ring, a connecting pipe installed on both the first and second conductive rings, the connecting pipe on the first conductive ring being fixedly connected to both the first conductive ring and the electromagnetic plate, the connecting pipe on the second conductive ring being rotatably connected to both the second conductive ring and the electromagnetic plate, the end of the connecting pipe on the second conductive ring near the electromagnetic plate being telescopically designed, and a moving mechanism cooperating with the second conductive ring being installed on the drive disk and the rotating platform.

[0018] Preferably, the moving mechanism includes a plurality of lead screws rotatably mounted on a drive disk, each lead screw having a threaded sleeve rotatably mounted on it, and a moving ring being fixedly mounted on the plurality of threaded sleeves, the moving ring being rotatably connected to a second conductive ring;

[0019] Each lead screw is fixedly mounted with a second gear, and multiple first incomplete gears that cooperate with the corresponding second gears are fixedly mounted on the rotating platform. Multiple second incomplete gears that cooperate with the corresponding second gears are fixedly mounted on the second conductive ring. The diameter of the first incomplete gear is larger than the diameter of the second incomplete gear.

[0020] Preferably, the drive plate includes a fixed plate and a drive motor. The fixed plate is fixedly connected to the tubular liquid outlet support, the drive motor is fixedly connected to the fixed plate, the drive end of the drive motor is fixedly connected to the rotating table, and a liquid outlet conduit is fixedly connected to the side of the tubular liquid outlet support.

[0021] The present invention also provides a method for producing ultrapure water based on the principle of reverse osmosis, comprising the above-mentioned apparatus for producing ultrapure water based on the principle of reverse osmosis, and further comprising the following steps:

[0022] S1. Low-purity water is introduced into the high-pressure pipe from the inlet pipe, and the introduced low-purity water is pressurized by an external pressurization device so that the pressure of the low-purity water in the high-pressure pipe is greater than the natural osmotic pressure of the low-purity water and ultrapure water. During the pressurization process, the water outlet at the bottom of the high-pressure pipe is closed by an electric control valve.

[0023] S2. The pressurized low-purity water will enter the filter membrane roll through the outlet hole on the high-pressure pipe. Under the obstruction of the side baffle, the ultrapure water after being filtered layer by layer by the filter membrane roll will seep out from the inside of the filter membrane roll, pass through the steel mesh support frame and enter the water outlet cover.

[0024] S3. As low-purity water enters the high-pressure pipe, the drive disc drives the rotating table to rotate, which in turn drives the high-pressure pipe to rotate. The high-speed rotation of the rotating table generates centrifugal force, which in turn drives the clamping assembly to operate and clamp the water outlet cover. This causes the water outlet cover to rotate along with the high-pressure pipe, giving the low-purity water in the high-pressure pipe a certain centrifugal force. This allows the low-purity water to diffuse faster after entering the filter membrane roll and accelerates the water outlet speed of the rotating ring, generating negative pressure suction. The centrifugal force generated is used to share some of the pressurization energy of the external pressurization equipment, reducing the energy consumption of the external pressurization equipment.

[0025] S4. The clamping assembly changes shape as the rotating table rotates, intermittently clamping the water outlet cover, causing the water outlet cover to rotate intermittently. The water outlet cover stops rotating to maintain the osmotic pressure inside the water outlet cover.

[0026] Compared with existing technologies, the advantages of this invention are:

[0027] 1. In the preparation of ultrapure water, this ultrapure water production device introduces low-purity water into a high-pressure pipe and then exits it from the filter membrane roll. After the low-purity water is squeezed out of the high-pressure pipe, its pressure is released instantaneously, and the molecular motion is accelerated, which is conducive to the diffusion of low-purity water, thereby improving the water output efficiency of low-purity water. At the same time, the water output area of ​​the filter membrane roll is large, so the ultrapure water output efficiency is high, effectively improving the preparation efficiency of ultrapure water.

[0028] 2. In the preparation of ultrapure water, this ultrapure water production device uses a rotatable rotating platform to drive the high-pressure pipe to rotate. The high-pressure pipe rotates at high speed during the water outlet process, generating a certain intensity of centrifugal force. Under the action of centrifugal force, the low-purity water has a squeezing force that forces it out of the liquid outlet of the high-pressure pipe. Combined with the additional pressure applied, the reverse osmosis pressure is achieved. This reduces the amount of additional pressure applied, lowers energy consumption, and thus reduces the cost of ultrapure water preparation. Furthermore, the centrifugal force generated by high-speed rotation also accelerates the diffusion rate of low-purity water within the filter membrane roll, making the low-purity water diffuse more evenly within the filter membrane roll and avoiding local blockage that could block the reverse osmosis water path.

[0029] 3. During the preparation of ultrapure water, this ultrapure water production device uses a clamping assembly to hold the outlet cover. The position of the clamping plate in the clamping assembly is adjusted by an energized assembly, causing the clamping assembly to intermittently clamp the outlet cover. The rotation of the high-pressure pipe causes the outlet cover to rotate intermittently through the clamping assembly, which in turn causes the ultrapure water inside the outlet cover to rotate, generating centrifugal force and accelerating the discharge of ultrapure water. Furthermore, during drainage, a negative pressure is generated inside the outlet cover, increasing the reverse osmosis force. This reduces the additional pressure required and further reduces energy consumption.

[0030] In summary, this invention uses a reverse inlet and outlet water method to prepare ultrapure water through reverse osmosis. During the reverse osmosis process, the filter membrane roll rotates to generate centrifugal force, which changes the reverse osmosis water outlet speed and improves the reverse osmosis water outlet efficiency. This not only effectively reduces the energy consumption of ultrapure water reverse osmosis preparation, but also improves the diffusion rate and diffusion uniformity of low-purity water, thereby improving the preparation efficiency of ultrapure water.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1: Referring to Figures 1-7, an apparatus for producing ultrapure water based on the principle of reverse osmosis includes a reverse osmosis unit and a tubular outlet support 4. The tubular outlet support 4 consists of a support and a concentrate discharge pipe. The filtered concentrate will be discharged from the concentrate discharge pipe.

[0050] The reverse osmosis unit includes an outlet cover 1, a cover is fixedly installed on the outlet cover 1, a high pressure pipe 7 is rotatably installed inside the outlet cover 1, an inlet pipe 5 is fixedly connected to the top of the high pressure pipe 7, multiple outlet holes 11 are opened on the high pressure pipe 7, and a filter membrane roll 10 is wrapped around the outside of the high pressure pipe 7.

[0051] The filter membrane roll 10 is a single, fully rolled-up filter membrane, which consists of a reverse osmosis membrane and a separator. The separator is used for water flow.

[0052] A steel mesh support frame 9 is fixedly installed on the outside of the filter membrane roll 10. Side baffles 8 that cooperate with the filter membrane roll 10 are fixedly installed on both sides of the steel mesh support frame 9. An outlet rotating ring 2 is rotatably installed on the outside of the outlet cover 1. A water pipe is fixedly installed on the outlet rotating ring 2 for discharging ultrapure water.

[0053] The side baffle 8 is used to seal both ends of the filter membrane roll 10 to prevent low-purity water from flowing out from both sides of the filter membrane roll 10, and to ensure that low-purity water is filtered layer by layer by the filter membrane roll 10.

[0054] Low-purity water is introduced into high-pressure pipe 7 from inlet pipe 5, and the introduced low-purity water is pressurized by external pressurization equipment so that the pressure of low-purity water in high-pressure pipe 7 is greater than the natural osmotic pressure of low-purity water and ultrapure water.

[0055] After pressurization, the low-purity water will enter the filter membrane roll 10 through the outlet hole 11 on the high-pressure pipe 7. Under the blocking effect of the side baffle 8, the ultrapure water after being filtered layer by layer by the filter membrane roll 10 will seep out from the inside of the filter membrane roll 10, pass through the steel mesh support frame 9 and enter the water outlet cover 1.

[0056] The steel mesh support frame 9 is used to wrap and fix the filter membrane roll 10 to prevent the filter membrane roll 10 from automatically unfolding under its own elastic force.

[0057] Example 2: The difference between this example and Example 1 is that, referring to Figures 1 and 5-15, a rotating platform 3 is rotatably mounted on the tubular liquid outlet support 4, and a drive disk 22 that cooperates with the rotating platform 3 is fixedly mounted on the tubular liquid outlet support 4.

[0058] The drive plate 22 includes a fixed plate and a drive motor. The fixed plate is fixedly connected to the tubular liquid outlet support 4, the drive motor is fixedly connected to the fixed plate, the drive end of the drive motor is fixedly connected to the rotating table 3, and the tubular liquid outlet support 4 has a liquid outlet conduit fixedly connected to its side. The filtered concentrate will be discharged from the liquid outlet conduit.

[0059] The rotating platform 3 is equipped with a clamping assembly 6 that cooperates with the water outlet cover 1. The rotating platform 3 is also fixedly equipped with an electric control valve 15 that is fixedly connected to the bottom of the high pressure pipe 7. The electric control valve 15 is rotatably connected to the tubular liquid outlet support 4.

[0060] During the pressurization process, the bottom outlet of the high-pressure pipe 7 is closed by the solenoid valve 15. The solenoid valve 15 is opened and closed intermittently. When it is open, it drains water, and when it is closed, it filters water.

[0061] The clamping assembly 6 includes multiple sliding plates 13 slidably mounted on the rotating platform 3. Each sliding plate 13 is fixedly mounted with a frame, and each frame is fixedly mounted with a clamping plate 12 that cooperates with the water outlet cover 1. Multiple linkage mechanisms 16 that cooperate with the corresponding sliding plates 13 are mounted on the rotating platform 3.

[0062] The linkage mechanism 16 includes a first rack 17 fixedly mounted on the sliding plate 13, a second rack 18 slidably mounted on the rotating table 3, a first gear 19 rotatably mounted on the rotating table 3 that meshes with both the first rack 17 and the second rack 18, a centrifugal ball 14 fixedly mounted on the second rack 18, and a reset structure that cooperates with the second rack 18 and a support structure that cooperates with the centrifugal ball 14 mounted on the rotating table 3.

[0063] As the rotating platform 3 rotates at high speed, it drives the centrifugal ball 14 to rotate. The rotation of the centrifugal ball 14 generates centrifugal force, which drives the centrifugal ball 14 to move away from the center point of the rotating platform 3. This drives the second rack 18 to move. The second rack 18 drives the first rack 17 to move closer to the center point of the rotating platform 3 through the first gear 19. This drives the clamping plate 12 to move closer to the water outlet cover 1 through the sliding plate 13 and the frame. The clamping plate 12 then abuts against the water outlet cover 1 to clamp it. The faster the rotation speed, the greater the centrifugal force of the centrifugal ball 14 and the greater the clamping force. At this time, the rotating platform 3 not only drives the high pressure pipe 7 to rotate, but also drives the water outlet cover 1 to rotate through the clamping assembly 6.

[0064] When the water outlet cover 1 rotates, the ultrapure water inside the water outlet rotating ring 2 will rotate, generating centrifugal force and flowing out of the water pipe at high speed. The outflow will cause the ultrapure water in the upper part of the water outlet cover 1 to be discharged, while the ultrapure water in the lower part of the water outlet cover 1 will remain in the water outlet cover 1 (only half is discharged each time, and the other half is used to maintain the osmotic pressure in the water outlet cover 1).

[0065] The reset structure includes a fixed plate fixedly installed on the rotating table 3, and an elastic reset telescopic rod 21 fixedly installed on the fixed plate. The telescopic end of the elastic reset telescopic rod 21 is fixedly connected to the second rack 18.

[0066] As the rotation speed of the rotating table 3 decreases, the centrifugal force of the centrifugal ball 14 decreases. At this time, the second rack 18 needs to be pulled back to its original position by the elastic reset telescopic rod 21 to reset the centrifugal ball 14.

[0067] The support structure includes a plate fixedly installed at the bottom of the rotating table 3, a support telescopic rod 20 fixedly installed on the plate, a connecting plate fixedly installed at the drive end of the support telescopic rod 20, the connecting plate being fixedly connected to the centrifugal ball 14, and a locking component that cooperates with the connecting plate being installed on the rotating table 3.

[0068] Because the centrifugal ball 14 is relatively heavy, it will detach from the rotating platform 3 when it is thrown out during rotation. At this time, the centrifugal ball 14 is in a suspended state, which will increase the friction between the second rack 18 and the rotating platform 3. This will increase the resistance to the movement of the second rack 18 on the rotating platform 3, affecting the normal sliding of the second rack 18. If a sliding distance is required, the centrifugal force required for the unsupported centrifugal ball 14 is different from that required for the supported centrifugal ball 14. The unsupported centrifugal ball 14 needs a higher rotation speed to push it.

[0069] A support structure is used here to support the centrifugal ball 14. The weight of the centrifugal ball 14 is borne by the support telescopic rod 20, which minimizes the friction between the second rack 18 and the rotating table 3, so that the second rack 18 moves more smoothly on the rotating table 3. Under the premise of ensuring centrifugal force, the required speed is lower and the energy consumption is lower.

[0070] Controlling whether the water outlet cover 1 rotates or not: The locking component includes a fixed frame fixedly installed at the bottom of the rotating platform 3, an electromagnetic plate 34 fixedly installed on the fixed frame, a permanent magnet plate 33 that cooperates with the electromagnetic plate 34 fixedly installed on the connecting plate, and an energizing component that cooperates with the electromagnetic plate 34 installed on the tubular liquid outlet support 4.

[0071] When the electromagnetic plate 34 is energized, it will generate an attractive force on the permanent magnet plate 33, pulling the permanent magnet plate 33 towards the center point of the rotating table 3, so that the centrifugal ball 14 is reset. At this time, the movement of the centrifugal ball 14 will drive the clamping plate 12 to move, so that the clamping plate 12 is separated from the water outlet cover 1, thus preventing the water outlet cover 1 from rotating with the rotating table 3.

[0072] After the electromagnetic plate 34 is de-energized, the permanent magnet plate 33 loses the attraction of the electromagnetic plate 34, and the centrifugal force of the centrifugal ball 14 will pull the second rack 18 again, causing the clamping plate 12 to clamp the water outlet cover 1.

[0073] The energized assembly includes a first conductive ring 23 rotatably mounted on a tubular liquid outlet support 4, and a second conductive ring 24 fitted on the tubular liquid outlet support 4 to cooperate with the first conductive ring 23. A connecting pipe 32 is installed on both the first conductive ring 23 and the second conductive ring 24. The connecting pipe 32 on the first conductive ring 23 is fixedly connected to the first conductive ring 23 and the electromagnetic plate 34. The connecting pipe 32 on the second conductive ring 24 is rotatably connected to the second conductive ring 24 and the electromagnetic plate 34. The end of the connecting pipe 32 on the second conductive ring 24 near the electromagnetic plate 34 is telescopic. A moving mechanism that cooperates with the second conductive ring 24 is installed on the drive disk 22 and the rotating table 3.

[0074] When the first conductive ring 23 comes into contact with the second conductive ring 24, it will cause the electromagnetic plate 34 to be energized and generate an attractive force. This part is existing electrical technology and will not be described in detail.

[0075] The rotation of the rotating platform 3 will cause the centrifugal ball 14 to rotate, and then drive the first conductive ring 23 and the second conductive ring 24 to rotate through the connecting pipe 32 (both the first conductive ring 23 and the second conductive ring 24 will rotate around the tubular liquid outlet support 4).

[0076] The end of the connecting tube 32 located on the second conductive ring 24 near the electromagnetic plate 34 is designed to be telescopic, so that the second conductive ring 24 will not get stuck when it moves, and the second conductive ring 24 can move smoothly.

[0077] The moving mechanism includes multiple lead screws 30 rotatably mounted on the drive disk 22. Each lead screw 30 is threadedly rotatably mounted with a threaded sleeve 31. A moving ring 25 is fixedly mounted on the multiple threaded sleeves 31. The moving ring 25 is rotatably connected to the second conductive ring 24.

[0078] Each lead screw 30 is fixedly mounted with a second gear 28. The rotating table 3 is fixedly mounted with multiple first incomplete gears 26 that cooperate with the corresponding second gears 28. The second conductive ring 24 is fixedly mounted with multiple second incomplete gears 27 that cooperate with the corresponding second gears 28. The diameter of the first incomplete gear 26 is larger than the diameter of the second incomplete gear 27.

[0079] As the rotating platform 3 and the second conductive ring 24 rotate, the first incomplete gear 26 and the second incomplete gear 27 will rotate. The first incomplete gear 26 and the second incomplete gear 27 are arranged in a staggered manner. When the first incomplete gear 26 disengages from the second gear 28, the second incomplete gear 27 meshes with the second gear 28. After the second incomplete gear 27 disengages from the second gear 28, the first incomplete gear 26 will mesh with the second gear 28 again (because the diameter of the second incomplete gear 27 is smaller than the diameter of the first incomplete gear 26, the two diameters are...). The difference is twice the diameter of the second gear 28, and the second gear 28 is located between the rotation path of the first incomplete gear 26 and the rotation path of the second incomplete gear 27. When the first incomplete gear 26 meshes with the second gear 28, it will drive the second gear 28 to rotate clockwise. When the second incomplete gear 27 meshes with the second gear 28, the second gear 28 will rotate counterclockwise (clockwise and counterclockwise are for ease of description, and the specific direction of rotation needs to be determined according to the specific reference diagram), thereby realizing the forward and reverse rotation of the second gear 28.

[0080] The rotation of the second gear 28 will drive the lead screw 30 to rotate, thereby causing the threaded sleeve 31 to move back and forth on the lead screw 30, which in turn drives the second conductive ring 24 to move up and down, realizing intermittent energization. As can be seen from the above, intermittent energization can realize the intermittent rotation of the water outlet cover 1.

[0081] If it is necessary to keep the water outlet cover 1 rotating continuously, the permanent magnet plate 33 can be replaced with an insulating plate. If it is necessary to keep the water outlet cover 1 stationary, the electromagnetic plate 34 needs to be replaced with a permanent magnet that attracts the permanent magnet plate 33.

[0082] The specific operating steps of this device are as follows:

[0083] Low-purity water is introduced into high-pressure pipe 7 through inlet pipe 5, and the introduced low-purity water is pressurized by external pressurization equipment so that the pressure of low-purity water in high-pressure pipe 7 is greater than the natural osmotic pressure of low-purity water and ultrapure water. During the pressurization process, the bottom outlet of high-pressure pipe 7 is closed by electric control valve 15.

[0084] After pressurization, the low-purity water will enter the filter membrane roll 10 through the outlet hole 11 on the high-pressure pipe 7. Under the blocking effect of the side baffle 8, the ultrapure water filtered by the filter membrane roll 10 will seep out from the inside of the filter membrane roll 10 and pass through the steel mesh support frame 9 into the water outlet cover 1.

[0085] As low-purity water enters the high-pressure pipe 7, the drive disc 22 drives the rotating table 3 to rotate, which in turn drives the high-pressure pipe 7 to rotate. The high-speed rotation of the rotating table 3 generates centrifugal force, which in turn drives the clamping assembly 6 to operate and clamp the water outlet cover 1, causing the water outlet cover 1 to rotate together with the high-pressure pipe 7. This gives the low-purity water in the high-pressure pipe 7 a certain centrifugal force, allowing the low-purity water to diffuse faster after entering the filter membrane roll 10 and accelerating the water outlet speed of the water outlet rotating ring 2, generating negative pressure suction. The generated centrifugal force is used to share some of the pressurization energy of the external pressurization equipment, reducing the energy consumption of the external pressurization equipment.

10. A method for producing ultrapure water based on the principle of reverse osmosis, used in the apparatus for producing ultrapure water based on the principle of reverse osmosis as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. Low-purity water is introduced into the high-pressure pipe (7) through the inlet pipe (5), and the low-purity water is pressurized by an external pressurization device so that the pressure of the low-purity water in the high-pressure pipe (7) is greater than the natural osmotic pressure of the low-purity water and the ultrapure water. During the pressurization process, the bottom outlet of the high-pressure pipe (7) is closed by the electric control valve (15). S2. The pressurized low-purity water will enter the filter membrane roll (10) through the outlet hole (11) on the high-pressure pipe (7). Under the blocking effect of the side baffle (8), the ultrapure water after being filtered layer by layer by the filter membrane roll (10) will seep out from the inside of the filter membrane roll (10), pass through the steel mesh support frame (9) and enter the water outlet cover (1). S3. While low-purity water enters the high-pressure pipe (7), the drive disc (22) drives the rotating table (3) to rotate. The rotating table (3) drives the high-pressure pipe (7) to rotate. The high-speed rotation of the rotating table (3) will generate centrifugal force. Under the action of centrifugal force, the clamping component (6) will operate to clamp the water outlet cover (1), so that the water outlet cover (1) rotates together with the high-pressure pipe (7), so that the low-purity water in the high-pressure pipe (7) has a certain centrifugal force, so that the low-purity water diffuses faster after entering the filter membrane roll (10), and accelerates the water outlet speed of the water outlet rotating ring (2), generating negative pressure suction. The generated centrifugal force is used to share part of the pressurization energy of the external pressurization equipment, reducing the energy consumption of the external pressurization equipment. S4. The clamping component (6) changes shape as the rotating table (3) rotates, intermittently clamping the water outlet cover (1) so that the water outlet cover (1) rotates intermittently. The water outlet cover (1) stops rotating to maintain the osmotic pressure inside the water outlet cover (1).
