Description

Technical Field

[0001] This invention relates to the field of reverse osmosis membrane cleaning technology, and in particular to an online reverse osmosis membrane cleaning system. Background Technology

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane with specific characteristics, mimicking a biological semi-permeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis is that, under pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus separating them from water. The membrane pores of a reverse osmosis membrane are extremely small, effectively removing dissolved salts, colloids, microorganisms, and organic matter from water. As the membrane is used, the desalination rate and permeate rate decrease. To ensure the membrane's lifespan, it needs to be cleaned.

[0003] Existing reverse osmosis membrane cleaning devices can only perform simple rinsing of the reverse osmosis membrane in the reverse osmosis membrane unit (the unit containing the reverse osmosis membrane). For some reverse osmosis membranes, simple rinsing is not enough to clean them thoroughly. It is necessary to remove the reverse osmosis membrane from the reverse osmosis membrane unit and manually take it to the cleaning chamber for cleaning using manual decontamination methods, which is inconvenient. Summary of the Invention

[0045] The beneficial effects of this invention are as follows:

[0046] When a simple flushing of the reverse osmosis membrane is required, connect the inlet water line, clear water line, and concentrate line to their respective ports. With the second valve closed, open the first valve to inject cleaning agent into the reverse osmosis membrane unit for flushing. During the initial flushing process, open the fourth and fifth valves and close the third and sixth valves. The concentrate output from the reverse osmosis membrane unit, containing a large amount of impurities, is poured into the wastewater tank, while the purified water output from the reverse osmosis membrane unit is filtered and then fed into the reagent tank via the transmission line. After flushing for a period of time, when the impurities in the concentrate output from the reverse osmosis membrane unit are reduced, close the fourth and fifth valves and open the third and sixth valves. The concentrate output from the reverse osmosis membrane unit 11 is filtered and then fed into the reagent tank via the transmission line, while the purified water output from the reverse osmosis membrane unit 11 is stored in the clear water tank. During the flushing process, the pH value of the cleaning agent is monitored using a pH measuring device. If the value exceeds the cleaning requirements, reagent is added to adjust the cleaning agent value to ensure its cleaning effect. A thermometer and heating rod are installed in the reagent tank to heat the cleaning agent, thereby improving its cleaning effect.

[0047] Once the pH of the circulating cleaning agent no longer changes significantly, close the first, fourth, and fifth valves, and open the second, third, and sixth valves. The purified water in the clear water tank is then fed into the reverse osmosis membrane unit for rinsing, cleaning the cleaning agent from the reverse osmosis membrane unit until there is no cleaning agent in the output water. The output concentrated water passes through the filter and enters the chemical tank, while the output purified water is circulated back into the clear water tank.

[0048] If the reverse osmosis membrane unit is found to be severely contaminated during the cleaning process, and the rinsing method cannot effectively clean the reverse osmosis membrane unit, then the reverse osmosis membrane is removed from the unit and placed in a deep cleaning device for deep cleaning.

[0049] Different cleaning methods are selected for each reverse osmosis membrane unit based on its varying degree of fouling, ensuring effective cleaning and improving cleaning efficiency.

[0050] This invention solves the problem raised in the background art: existing reverse osmosis membrane cleaning devices can only perform simple rinsing of the reverse osmosis membrane in the reverse osmosis membrane device (the device containing the reverse osmosis membrane). For some reverse osmosis membranes, simple rinsing is not enough to clean them thoroughly. It is necessary to remove the reverse osmosis membrane from the reverse osmosis membrane device and manually take it to the cleaning chamber for cleaning by manual decontamination, which is inconvenient.

[0059] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0060] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0061] Example 1: This embodiment of the invention discloses an online cleaning system for reverse osmosis membranes, such as... Figure 1As shown, the device includes a base plate 1, on which are installed the following: a reverse osmosis membrane device 11, an inlet water pipe 3, a clean water pipe 4, a concentrate water pipe 5, a transmission pipe 6, a wastewater tank 7, a clean water tank 8, a filter 9, a reagent tank 10, and a deep cleaning device 12.

[0062] The raw water inlet 1101 of the reverse osmosis membrane unit 11 is connected to the clear water tank 8 and the reagent tank 10 respectively through the inlet pipe 3;

[0063] The inlet of the clear water tank 8 is connected to the clean water outlet 1102 of the reverse osmosis membrane device 11 through the clear water pipe 4;

[0064] The inlet of the wastewater tank 7 is connected to the concentrated water outlet 1103 of the reverse osmosis membrane device 11 through the concentrated water pipeline 5;

[0065] The first inlet of filter 9 is connected to the clean water outlet 1102 of reverse osmosis membrane device 11 through clean water pipeline 4, and the second inlet of filter 9 is connected to the concentrated water outlet 1103 of reverse osmosis membrane device 11 through concentrated water pipeline 5.

[0066] The inlet of the reagent tank 10 is connected to the outlet of the filter 9 via the transmission pipe 6. The reagent tank 10 stores existing reagents for cleaning the reverse osmosis membrane.

[0067] Specifically, during normal operation of the reverse osmosis membrane device 11, raw water enters the device through the raw water inlet 1101. A plug 1108 prevents the raw water from directly passing through the gap between the outer shell 1104 and the membrane 1107 (i.e., the reverse osmosis membrane). The pressure of the water flow allows pure water molecules to pass through the membrane 1107 and enter its inner layer. The purified water then enters the central tube 1105 through the water collection hole 1106 and flows out of the reverse osmosis membrane device 11 through the purified water outlet 1102. Other impurities in the raw water remain on the outside of the reverse osmosis membrane. The concentrated water from the outside of the reverse osmosis membrane flows out of the reverse osmosis membrane device 11 through the concentrated water outlet 1103. This is prior art and can be found in CN212832964U.

[0068] Preferably, the water inlet pipe 3 includes:

[0069] The first pipe section 301 is connected at one end to the raw water inlet of the reverse osmosis membrane device 11, and a booster pump 302 is connected to the first pipe section 301.

[0070] The second pipe section 303 has one end connected to the water outlet of the medicine tank 10, and the other end connected to the other end of the first pipe section 301. A first valve 304 is installed on the second pipe section 303.

[0071] The third pipe section 305 is connected at one end to the outlet of the clean water tank 8 and at the other end to the first pipe section 301. A second valve 306 is provided on the third pipe section 305.

[0072] Preferably, the clean water pipeline 4 includes:

[0073] The fourth pipe section 401, one end of which is connected to the purified water outlet 1102 of the reverse osmosis membrane device 11;

[0074] The fifth pipe section 402 is connected at one end to the inlet of the clean water tank 8 and at the other end to the fourth pipe section 401. A third valve 403 is provided on the fifth pipe section 402.

[0075] The sixth pipe section 404 is connected at one end to the first water inlet of the filter 9 and at the other end to the fourth pipe section 401. A fourth valve 405 is connected to the sixth pipe section 404.

[0076] Preferably, the concentrate pipeline 5 includes:

[0077] The seventh pipe section 501, one end of which is connected to the concentrate outlet 1103 of the reverse osmosis membrane device 11;

[0078] The eighth pipe section 502 is connected at one end to the inlet of the wastewater tank 7 and at the other end to the seventh pipe section 501. The eighth pipe section 502 is connected to the fifth valve 503.

[0079] The ninth pipe section 504 is connected at one end to the second inlet of the filter 9 and at the other end to the seventh pipe section 501. A sixth valve 505 is connected to the ninth pipe section 504.

[0080] Preferably, the reagent tank 10 is provided with a reagent inlet, and the reagent tank 10 is provided with a heating rod, a thermometer, and a pH measuring device. The reagent stored in the reagent tank 10 can be used to remove impurities from the reverse osmosis membrane.

[0081] In this invention, the reverse osmosis membrane device 11, the inlet water pipe 3, the clear water pipe 4, the concentrate water pipe 5, the transmission pipe 6, the wastewater tank 7, the clear water tank 8, the filter 9, the reagent tank 10, and the deep cleaning device 12 are all on the same production line and arranged on the same base plate 1, which is convenient to use.

[0082] The working principle and beneficial effects of the above technical solution are as follows: When a simple flushing of the reverse osmosis membrane is required, the inlet water pipe 3, the clear water pipe 4, and the concentrate pipe 5 are connected to their respective ports. The second valve 306 is closed, and the first valve 304 is opened to inject cleaning agent into the reverse osmosis membrane device 11 for flushing. During the initial flushing process, the fourth valve 405 and the fifth valve 503 are opened, and the third valve 403 and the sixth valve 505 are closed. The concentrate water with a large amount of impurities output from the reverse osmosis membrane device 11 is poured into the wastewater tank 7, while the pure water output from the reverse osmosis membrane device 11 enters the filter 9 for filtration and is then input into the chemical tank 10 through the transmission pipe 6. When flushing... After a period of time, when there are fewer impurities in the concentrate output by the reverse osmosis membrane unit 11, the fourth valve 405 and the fifth valve 503 are closed, and the third valve 403 and the sixth valve 505 are opened. The concentrate output by the reverse osmosis membrane unit 11 enters the filter 9 for filtration and then enters the chemical tank 10 through the transmission pipeline 6. The purified water output by the reverse osmosis membrane unit 11 enters the clean water tank 8 for storage. During the rinsing process, the pH value of the cleaning agent is detected by the pH measuring device. When the pH value exceeds the cleaning requirements, chemicals are added to adjust the pH value of the cleaning agent to ensure the cleaning effect of the cleaning agent. A thermometer and a heating rod are installed in the chemical tank 10 to heat the cleaning agent and improve the cleaning effect of the cleaning agent.

[0083] Once the pH of the circulating cleaning agent no longer changes significantly, close the first valve 304, the fourth valve 405, and the fifth valve 503, and open the second valve 306, the third valve 403, and the sixth valve 505. The purified water in the clear water tank 8 is fed into the reverse osmosis membrane device 11 for rinsing, cleaning the cleaning agent in the reverse osmosis membrane device 11 until there is no cleaning agent in the output water. The output concentrated water passes through the filter 9 and enters the chemical tank 10, while the output purified water enters the clear water tank 8 for circulation.

[0084] If the reverse osmosis membrane unit is found to be severely contaminated during the cleaning process, and the rinsing method cannot effectively clean the reverse osmosis membrane unit 11, then the reverse osmosis membrane is removed from the unit and placed into the deep cleaning device 12 for deep cleaning.

[0085] Different cleaning methods are selected for each reverse osmosis membrane unit based on its varying degree of fouling, ensuring effective cleaning and improving cleaning efficiency.

[0086] This invention solves the problem raised in the background art: existing reverse osmosis membrane cleaning devices can only perform simple rinsing of the reverse osmosis membrane in the reverse osmosis membrane device (the device containing the reverse osmosis membrane). For some reverse osmosis membranes, simple rinsing is not enough to clean them thoroughly. It is necessary to remove the reverse osmosis membrane from the reverse osmosis membrane device and manually take it to the cleaning chamber for cleaning by manual decontamination, which is inconvenient.

[0095] Rotating rod 32, which is rotatably connected to the bottom surface of lifting groove 133, and rotating rod 32 is connected to output shaft 15 through belt drive device 33;

[0096] A rotating plate 34 is fixedly connected to a rotating rod 32, and a protrusion 35 is provided on the lower surface of the rotating plate 34;

[0097] Mounting bracket 36 includes a mounting part 361 and a sliding part 362. The mounting part 361 is located inside the cleaning tank 134. A spring 37 is fixedly connected between the lower surface of the mounting part 361 and the bottom surface inside the cleaning tank 134. The sliding part 362 is fixedly connected to the upper rear side of the mounting part 361 and is slidably mounted on the rotating rod 32 in the vertical direction.

[0098] Preferably, the cleaning device includes: a water supply pipe 30, one end of which is inserted into the bottom of the detergent chamber 132, and the other end of which is connected to the nozzle 29. A water pump 31 is connected to the water supply pipe 30.

[0099] Preferably, the cleaning device further includes:

[0100] A toggle plate 18 is fixedly connected to the upper surface of the annular wheel 16;

[0101] A sliding rod 19 slides through the front wall of the detergent chamber 132 in the front-back direction, and a fixing plate 2 is fixedly connected to the upper surface of the sliding rod 19.

[0102] A push plate 20 is fixedly connected to the rear end of the sliding rod 19. The push plate 20 is disposed inside the detergent chamber 132 and is used to contact the actuating plate 18.

[0103] Spring 21, one end of which is fixedly connected to the outer wall of the detergent chamber 132, and the other end of which is fixedly connected to the fixing plate 2;

[0104] A connecting plate 22 is fixedly connected to the front end of the sliding rod 19. The connecting plate 22 is located outside the detergent chamber 132. A brush 23 is fixedly connected to the lower end of the connecting plate 22.

[0105] Rack 24, which is fixedly connected to the lower side of sliding rod 19, and is disposed outside detergent chamber 132;

[0108] The working principle and beneficial effects of the above technical solution are as follows: When some reverse osmosis membranes are severely fouled, they need to be removed separately for cleaning. First, the removed reverse osmosis membrane is fixed on the mounting part 361 of the mounting frame 36. Cleaning agent is injected into the cleaning agent chamber 132. The motor 14 is started, and the motor 14 drives the annular wheel 16 to rotate. The stirring rod 17 fixed on the lower surface of the annular wheel 16 stirs the cleaning agent to ensure that the components in the cleaning agent are uniform and to maintain a good cleaning effect. As the annular wheel 16 rotates, the actuating plate 18 fixedly connected to the upper surface of the annular wheel 16 will periodically contact the pushing plate 20, and under the elastic force of the spring 21, the sliding rod 19 moves back and forth, thereby driving the connecting plate 22 to move, so that... The brush 23 connected to the lower end of the connecting plate 22 cleans the surface of the reverse osmosis membrane. As the sliding rod 19 moves back and forth, the rack 24 fixed to the lower surface of the sliding rod 19 meshes with the gear 27, driving the rotating wheel 26 to rotate. The nozzle 29 adjusts its angle as the rotating wheel 26 rotates. The nozzle 29 draws cleaning agent from the detergent chamber 132 through the water supply pipe 30 and sprays it. Together with the brush 23, it can thoroughly clean the surface of the reverse osmosis membrane. The rotating rod 32 rotates with the output shaft 15, driving the rotating plate 34 to rotate. The protrusion 35 on the lower surface of the rotating plate 34 periodically presses down on the mounting bracket 36. Combined with the upward elastic force of the spring 37, the reverse osmosis membrane body is periodically immersed in the cleaning agent, improving the cleaning effect on the reverse osmosis membrane body.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
