Description

Technical Field

[0001] This invention relates to the field of high-salt ammonia nitrogen wastewater treatment technology, specifically to a vibration-type anti-crystallization and scaling device for reverse osmosis membrane modules used in high-salt ammonia nitrogen wastewater treatment. Background Technology

[0002] High-salinity ammonia nitrogen wastewater is widely generated in industries such as coal chemical engineering, shale gas extraction, landfill leachate treatment, fertilizer production, and pharmaceuticals. This wastewater typically contains high concentrations of divalent ions such as calcium, magnesium, barium, and strontium, as well as scale-forming anions such as sulfate, carbonate, and phosphate. Ammonia nitrogen can also react with some ions (such as magnesium and phosphate) to form sparingly soluble salts like magnesium ammonium phosphate (struvite). On the concentration side of the reverse osmosis membrane, the ion concentration increases sharply with increasing water flux. When the ion product exceeds the solubility product, heterogeneous nucleation easily occurs on the membrane surface, in the flow channel mesh, and inside the membrane module, forming crystalline or dense scale layers.

[0003] To overcome the aforementioned problems, researchers have recently attempted to couple vibration technology with the reverse osmosis process. For example, they have used ultrasonic vibration, mechanical vibration, or hydraulic oscillation to induce micro-amplitude, high-frequency motion in the membrane module, thereby hindering particulate matter deposition on the membrane surface and promoting the removal of existing scale or crystals. However, existing vibration-assisted reverse osmosis devices generally suffer from the following shortcomings: Vibration cleaning can only remove scale or crystals, but large particles or colloids remain inside the membrane module after removal. If they are not removed in time, they will cause secondary wear or block the flow channel under vibration, resulting in a short-lasting cleaning effect. Most vibratory reverse osmosis units rely solely on the feed water flow to carry away detached materials. However, for high-salt ammonia nitrogen wastewater systems, the detached materials typically have a high specific gravity (such as magnesium ammonium phosphate and calcium sulfate crystals), making it difficult to completely remove them using only axial or tangential flushing, which can easily lead to the accumulation of "dead zones." Therefore, it is necessary to develop a reverse osmosis membrane module anti-crystallization and anti-scaling device suitable for treating high-salt ammonia nitrogen wastewater, capable of actively removing scale and crystals from inside the membrane module through vibration. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a vibration-type anti-crystallization and scaling device for reverse osmosis membrane modules used in high-salt ammonia nitrogen wastewater treatment, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a vibration-type anti-crystallization and scaling device for reverse osmosis membrane modules used in high-salt ammonia nitrogen wastewater treatment, comprising: Mounting frame, with the main body of the reverse osmosis membrane module disposed on the outside of the mounting frame; The vibration mechanism includes a U-shaped plate disposed inside the mounting frame, with connecting rings fixedly connected to both ends of the U-shaped plate, a drive motor mounted on the outside of the U-shaped plate, a cam fixedly connected to the output shaft of the drive motor, and two sets of symmetrically distributed springs fixedly connected to the outside of the U-shaped plate, with the ends of the two sets of springs being fixedly connected to the inner wall of the mounting frame. The water outlet mechanism includes a first connector installed at the water outlet end of the main body of the reverse osmosis membrane module. The water outlet of the first connector is fixedly connected to a water outlet pipe. A transfer tank is installed at the end of the water outlet pipe away from the first connector. An air supply pipe is installed on the top of the transfer tank. The water inlet mechanism includes a second connector installed at the water inlet end of the main body of the reverse osmosis membrane module. The water inlet end of the second connector is fixedly connected to a water inlet pipe. A three-way valve is installed at one end of the water inlet pipe near the second connector. A wastewater pipe is fixedly connected to the water inlet pipe through the three-way valve.

[0006] Preferably, the mounting bracket has four fixed feet that are symmetrically distributed in pairs on its outer side, and the outer side of each fixed foot has a through mounting hole.

[0007] Preferably, the inner wall of the mounting bracket is fixedly connected with two vertically symmetrically distributed guide rods, and the top of the U-shaped plate has two through sliding holes, with the guide rods slidably connected to the inner wall of the sliding holes.

[0008] Preferably, a motor base is fixedly connected to the outer side of the U-shaped plate, the drive motor is fixedly connected to the top of the motor base, and the output shaft of the drive motor passes through the U-shaped plate and is rotatably connected to the U-shaped plate through a bearing.

[0009] Preferably, a delivery pipe is installed on the side of the transfer tank away from the water outlet pipe, a first valve is installed at the end of the delivery pipe near the transfer tank, and a second valve is installed at the end of the air supply pipe near the transfer tank.

[0010] Preferably, a fixing frame is fixedly connected to the bottom of the transfer tank.

[0011] Preferably, a wastewater storage tank is provided below the mounting frame, and a first water pump is installed next to the wastewater storage tank. The outlet of the first water pump is connected to the end of the inlet pipe away from the second connector, and the pump outlet of the first water pump is fixedly connected to a pumping pipe that communicates with the inside of the wastewater storage tank.

[0012] Preferably, a wastewater tank is provided below the mounting bracket, and the end of the wastewater pipe away from the three-way valve extends into the interior of the wastewater tank, and an inclined filter membrane is provided inside the wastewater tank.

[0013] Preferably, a second water pump is provided between the wastewater storage tank and the wastewater container. The pump's inlet is fixedly connected to a connecting pipe that communicates with the inside of the wastewater container, and the pump's outlet is fixedly connected to a return pipe that communicates with the inside of the wastewater storage tank.

[0014] Preferably, the wastewater storage tank is equipped with a water inlet pipe at the top, and both the middle sections of the inlet pipe and the middle sections of the outlet pipe are designed to be retractable.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. This invention utilizes the rotation of a cam driven by a drive motor when crystallization or scaling occurs in the main body of the reverse osmosis membrane module. This causes the main body of the reverse osmosis membrane module to vibrate, dislodging the crystallized or scaled parts at the inlet end. Simultaneously, filtered wastewater is injected at the outlet end to backwash the main body of the reverse osmosis membrane module. The two processes work together to thoroughly dislodge the internal debris from the main body of the reverse osmosis membrane module and discharge it into the wastewater treatment system, thereby significantly improving the long-term operational stability and service life of the reverse osmosis membrane module.

[0016] 2. By setting up a transfer tank, an air supply pipe, a first valve, and a second valve, the present invention utilizes the filtered wastewater temporarily stored inside the transfer tank and the pressure provided by the air supply pipe to backwash the reverse osmosis membrane module during backwashing. The entire backwashing process does not require the use of external cleaning water, thus reducing water consumption.

[0017] 3. By setting up a three-way valve, wastewater pipe and wastewater tank, the wastewater carrying crystals and scale will be discharged from the wastewater treatment system through the wastewater pipe when the reverse osmosis membrane module is backwashed. This avoids the crystals and scale remaining in the pipe after cleaning, prevents the wastewater treatment system from being blocked, and ensures the subsequent treatment efficiency of high-salt ammonia nitrogen wastewater.

[0018] 4. By setting up a filter membrane and a second water pump, the wastewater generated during the backwashing of the reverse osmosis module is filtered by the filter membrane and then transported back to the wastewater storage tank. After being mixed with untreated high-salt ammonia nitrogen wastewater, it is then treated again by the main body of the reverse osmosis membrane module, thus avoiding secondary pollution of the environment by the wastewater generated during backwashing.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] The present invention will be further described below with reference to embodiments. Example 1

[0024] Reference Figure 1 and Figure 4-6 The first embodiment of the present invention discloses a vibration-type anti-crystallization and scaling device for reverse osmosis membrane modules of high-salt ammonia nitrogen wastewater, comprising: Mounting frame 1, with reverse osmosis membrane module body 2 installed on the outside of mounting frame 1; The vibration mechanism 3 includes a U-shaped plate 35 installed inside the mounting frame 1. Connecting rings 31 are fixedly connected to both ends of the U-shaped plate 35. A drive motor 37 is mounted on the outside of the U-shaped plate 35. A cam 33 is fixedly connected to the output shaft of the drive motor 37. Two sets of symmetrically distributed springs 32 are fixedly connected to the outside of the U-shaped plate 35, with one end of each set of springs fixedly connected to the inner wall of the mounting frame 1. When crystallization or scaling occurs in the reverse osmosis membrane module body 2, the drive motor 37 rotates the cam 33, and the springs 32, in conjunction with their resetting action, cause the entire reverse osmosis membrane module body 2 to generate high-frequency, low-amplitude mechanical vibration. This vibration can directly dislodge the crystals or scaling adhering to its inlet end and the internal reverse osmosis membrane surface, loosening and removing them, creating favorable conditions for subsequent backflushing. The combined effect of vibration and backflushing thoroughly removes the dislodged crystals and scaling, thereby significantly improving the long-term operational stability and service life of the reverse osmosis membrane module.

[0025] Specifically, the mounting frame 1 has four fixed feet that are symmetrically distributed in pairs on the outside. The fixed feet have through mounting holes on the outside. Through the fixed feet and mounting holes, the entire device can be firmly installed in the predetermined position, ensuring that the device remains stable when the vibration mechanism 3 is working, avoiding displacement or loosening of the connecting pipes due to vibration, and ensuring that the vibration energy is effectively transferred to the reverse osmosis membrane module 2, rather than being absorbed or dispersed by the frame.

[0026] Specifically, two vertically symmetrically distributed guide rods 34 are fixedly connected to the inner wall of the mounting bracket 1. Two through-holes are opened at the top of the U-shaped plate 35. The guide rods 34 are slidably connected to the inner wall of the through-holes. The sliding fit between the guide rods 34 and the through-holes provides precise vertical movement guidance for the U-shaped plate 35 and the reverse osmosis membrane module body 2 mounted on it. This ensures that the vibration direction generated under the action of the cam 33 and spring 32 is unique and stable, avoiding lateral swaying or torsion. This allows the vibration energy to be concentrated on the crystallization and scaling areas, improving the efficiency and reliability of vibration cleaning. It also prevents damage to the reverse osmosis membrane module body 2 and its connecting pipelines caused by irregular vibration.

[0027] Specifically, a motor base 36 is fixedly connected to the outside of the U-shaped plate 35, and a drive motor 37 is fixedly connected to the top of the motor base 36. The output shaft of the drive motor 37 passes through the U-shaped plate 35 and is rotatably connected to the U-shaped plate 35 through a bearing. The motor base 36 provides a stable mounting platform for the drive motor 37, while the bearing connection ensures the smoothness of the motor output shaft when driving the cam 33 to rotate at high speed, reducing friction and energy loss, so that the cam 33 can continuously and stably generate vibration, ensuring the continuity and effectiveness of the vibration cleaning process. Example 2

[0028] Reference Figure 1-3This is the second embodiment of the present invention, which differs from the first embodiment in that: The water outlet mechanism 4 includes a first connector 45 installed at the water outlet end of the reverse osmosis membrane module body 2. A water outlet pipe 44 is fixedly connected to the outlet of the first connector 45. A transfer tank 42 is installed at the end of the water outlet pipe 44 furthest from the first connector 45. An air supply pipe 43 is installed on the top of the transfer tank 42. During normal wastewater treatment, the purified water filtered by the reverse osmosis membrane module body 2 is stored in the transfer tank 42 through the water outlet pipe 44. When backwashing is required, the transfer tank 42 serves as the flushing water source. Compressed air is injected into the transfer tank 42 using an external air source connected to the air supply pipe 43. Under air pressure, the temporarily stored filtered wastewater inside the transfer tank 42 is forced back into the reverse osmosis membrane module body 2, achieving backwashing of the membrane module. The entire process does not require external cleaning water, greatly reducing water consumption.

[0029] Specifically, a delivery pipe 41 is installed on the side of the transfer tank 42 away from the outlet pipe 44. A first valve is installed at the end of the delivery pipe 41 closest to the transfer tank 42, and a second valve is installed at the end of the air supply pipe 43 closest to the transfer tank 42. In the normal wastewater treatment process, the first valve is open, and the treated clean water is sent to the next process through the delivery pipe 41; the second valve is closed to prevent gas from entering. In the backwash mode, the first valve is closed, cutting off the delivery of clean water to the subsequent process, while the second valve is open, allowing compressed air to enter the transfer tank 42. By switching and controlling the first and second valves, the system can precisely switch between the "normal water production" and "backwash" working states, ensuring the independence and controllability of the cleaning process.

[0030] Specifically, a fixing frame 46 is fixedly connected to the bottom of the transfer tank 42. The fixing frame 46 is used to securely fix the transfer tank 42 to the mounting frame 1 or other support structure to prevent the transfer tank 42 from shifting or tilting due to pipeline vibration or external impact, and to ensure the stability of its internal liquid level and the reliable connection between the gas supply pipe 43 and the delivery pipe 41.

[0031] The water inlet mechanism 5 includes a second connector 56 installed at the water inlet end of the reverse osmosis membrane module 2. A water inlet pipe 57 is fixedly connected to the water inlet end of the second connector 56. A three-way valve 55 is installed at the end of the water inlet pipe 57 near the second connector 56. A wastewater pipe 58 is fixedly connected to the water inlet pipe 57 via the three-way valve 55. During backflushing, the three-way valve 55 is switched to connect the water inlet pipe 57 to the wastewater pipe 58, while disconnecting it from the first water pump 54 and the wastewater storage tank 51. In this way, the wastewater carrying a large amount of crystals and scale, which is backflushed from the water inlet end of the reverse osmosis membrane module 2, will not flow back to the wastewater storage tank 51, but will directly enter the wastewater pipe 58 through the three-way valve 55 and be discharged in a directed manner. This effectively avoids the crystals and scale remaining inside the pipes after cleaning, preventing blockages in the wastewater treatment system and ensuring the efficiency of subsequent treatment of high-salt ammonia nitrogen wastewater.

[0032] Specifically, a wastewater storage tank 51 is installed below the mounting frame 1, and a first water pump 54 is installed next to the wastewater storage tank 51. The outlet of the first water pump 54 is connected to the end of the inlet pipe 57 away from the second connector 56. The suction port of the first water pump 54 is fixedly connected to a suction pipe 53 that communicates with the inside of the wastewater storage tank 51. During normal treatment, the first water pump 54 draws high-salt ammonia nitrogen wastewater from the wastewater storage tank 51 through the suction pipe 53 and pumps it into the inlet pipe 57 to provide raw water for treatment to the main body 2 of the reverse osmosis membrane module. This design ensures the stability and continuity of wastewater supply.

[0033] Specifically, a wastewater tank 510 is located below the mounting bracket 1. The end of the wastewater pipe 58 furthest from the three-way valve 55 extends into the wastewater tank 510. Inside the wastewater tank 510 is a sloped filter membrane 59. Wastewater generated from backwashing flows into the wastewater tank 510 via the wastewater pipe 58 and first passes through the sloped filter membrane 59. The filter membrane 59 effectively intercepts solid crystals and scale particles in the wastewater, while the filtered clear liquid passes through the filter membrane 59 and collects at the bottom of the wastewater tank 510. The sloped design helps the trapped solids slide down under gravity, preventing premature clogging of the filter membrane 59 and extending its effective working time.

[0034] Specifically, a second water pump 512 is installed between the wastewater storage tank 51 and the wastewater tank 510. The pump's inlet is fixedly connected to a connecting pipe 511 that communicates with the inside of the wastewater tank 510, and its outlet is fixedly connected to a return pipe 513 that communicates with the inside of the wastewater storage tank 51. The pump draws the clarified liquid filtered by the filter membrane 59 through the connecting pipe 511 and then returns it to the wastewater storage tank 51 through the return pipe 513 to mix with the untreated high-salt ammonia nitrogen wastewater. This allows the wastewater generated by backwashing to be recycled, avoiding secondary environmental pollution that may be caused by direct discharge, while also recovering water resources and improving the overall environmental friendliness and economy of the system.

[0035] Specifically, a water inlet pipe 52 is installed on the top of the wastewater storage tank 51. The water inlet pipe 52 is used to replenish the wastewater storage tank 51 with high-salt ammonia nitrogen wastewater to be treated. The middle sections of the inlet pipe 57 and the outlet pipe 44 are both designed to be telescopic. The telescopic design of the middle sections of the inlet pipe 57 and the outlet pipe 44 can perfectly adapt to the vertical vibration generated by the vibration mechanism 3 during operation, avoiding fatigue fracture or leakage at the connection due to repeated vibration of the rigid connection pipes, and ensuring the sealing and structural integrity of the device during the vibration cleaning process.

[0036] The remaining structure is the same as that in Example 1.

[0037] The workflow of this invention is as follows: When treating high-salt ammonia nitrogen wastewater, the wastewater enters the wastewater storage tank 51 through the water inlet pipe 52. Driven by the first water pump 54, it enters the reverse osmosis membrane module 2 through the inlet pipe 57 and the second connector 56. After being filtered by the reverse osmosis membrane inside the reverse osmosis membrane module 2, it is discharged through the first connector 45 and transported to the transfer tank 42 for storage through the outlet pipe 44. Excess wastewater is transported to the next process through the conveying pipe 41. When cleaning the inside of the reverse osmosis membrane module 2, the first valve and the first water pump 54 are closed, the second valve is opened and the drive motor 37 is started. The drive motor 37 drives the cam 33 to rotate through the output shaft. Under the action of the spring 32, the reverse osmosis membrane module 2 vibrates up and down, shaking off the crystals and scale inside the reverse osmosis membrane module 2. The detached material after shaking off stays at the inlet end of the reverse osmosis membrane module 2. Air is injected into the transfer tank 42 through the air supply pipe 43 via an external air source. Under pressure, the treated wastewater in the transfer tank 42 is reversed and enters the reverse osmosis membrane module 2. The reverse osmosis membrane inside the reverse osmosis membrane module 2 is reverse-flushed. With the cooperation of the vibration structure, the crystals and scale on the reverse osmosis membrane are further removed. The detached crystals and scale are discharged through the three-way valve 55 and wastewater pipe 58 and enter the wastewater tank 510. After being filtered by the filter membrane 59, they are stored inside the wastewater tank 510. The second water pump 512 draws wastewater from the wastewater tank 510 through the connecting pipe 511 and returns it to the wastewater storage tank 51 through the return water pipe 513, thus cleaning the main body 2 of the reverse osmosis membrane module and achieving the purpose of preventing the reverse osmosis membrane module from vibrating to prevent crystallization and scaling in high-salt ammonia nitrogen wastewater.
