[0012] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0013] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0014] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0015] In order to solve the above technical problems, Figure 1As shown, the utility model designs an industrial deionized water generating system, including a water reservoir 1, a water treatment device, and a deionized water storage tank 2. The water treatment device includes a first multi-media filter 3, a second multi-media filter 4, a reducing agent adding mechanism 5, an activated carbon adsorption device 6, a precision filter 7, a high-pressure water pump 8, a first reverse osmosis membrane group 9, and a second reverse osmosis membrane group 10. The water reservoir 1 is used to store a water source to be treated. The water reservoir 1 is connected to the inlet of the first multi-media filter 3 through a first water conduit 11. The first water conduit 11 branches out a second water conduit 12. The second water conduit 12 is connected to the second multi-media filter 4. The outlet of the first multi-media filter 3 is connected to the inlet of the activated carbon adsorption device 6 through a third water conduit 13. The outlet of the second multi-media filter 4 is connected to a fourth water conduit 14. The fourth water conduit 14 is connected to the third water conduit 13, and the reducing agent adding mechanism 5 is connected to the fourth water conduit 14. When the pollution degree of the incoming water is high, the water can flow from the second water conduit 12 into the second multi-media filter 4. The multi-media filter can pass the water with high turbidity through a certain thickness of granular or non-granular materials under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment to remove turbidity and soften water. As a pre-stage pretreatment method, a reducing agent is added during the dewatering. The reducing agent can be selected from sodium bisulfite, etc., to prevent the subsequent reverse osmosis membrane surface from being contaminated and damaged by microbial oxidants and suspended impurities, thereby ensuring the long-term stable operation of the reverse osmosis device. If the pollution degree of the incoming water is low, it is directly allowed to flow into the first multi-media filter 3 through the first water conduit 11 and be dewatered, which can save costs.

[0016] The inlets and outlets of the first multi-media filter 3, the second multi-media filter 4, the activated carbon adsorption device 6 and the precision filter 7 are all provided with stop valves 15, which have a relatively simple structure, are convenient to manufacture and maintain, and are easy to adjust and control.

[0017] When the water to be treated passes through the activated carbon adsorption device 6, the odor, natural and synthetic dissolved organic matter, micro-pollutants, etc. of the water can be effectively removed. The outlet of the activated carbon adsorption device 6 is connected to the precision filter 7 through the fifth water conduit 16. The precision filter can efficiently remove solid particles in the water. The outlet of the precision filter 7 is connected to the high-pressure water pump 8. The high-pressure water pump 8 is connected to the first reverse osmosis membrane group 9 through the sixth water conduit 17. The high-pressure water pump 8 works continuously as a power source for water flow to make it flow into the first reverse osmosis membrane group 9. Reverse osmosis is to separate these substances and water under the action of a pressure higher than the osmotic pressure of the solution based on the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water. The outlet of the first reverse osmosis membrane group 9 is connected to a seventh water conduit 18, and the seventh water conduit 18 branches into an eighth water conduit 19 and a ninth water conduit 20. The eighth water conduit 19 is connected to the second reverse osmosis membrane group 10, and the outlet of the second reverse osmosis membrane group 10 is connected to a tenth water conduit 21. The sixth water conduit 17, the eighth water conduit 19, the ninth water conduit 20 and the tenth water conduit 21 are all provided with a ball valve 22, and the ball valve 22 can be used for regulating and controlling the fluid. In the fully open or fully closed state, the fluid flows unimpeded, and the flow control is stable. Through the control and regulation of the ball valve, the water can be processed again by the second reverse osmosis membrane group 10 after passing through the first reverse osmosis membrane group 9 or directly exported. Corresponding adjustments are made according to different water quality requirements, which is more flexible and has better adaptability.

[0018] The tenth water conduit 21 is connected to the deionized water storage tank 2 after being combined with the ninth water conduit 20. The deionized water storage tank 2 is provided with a float valve 23. The upper side of the deionized water storage tank 2 is also provided with an overflow port 24. The setting of the float valve 23 can close the water inlet pipe of the deionized water storage tank 2 when the liquid level is too high. The overflow port 24 can discharge part of the water to eliminate the pressure when the water level is too high.

[0019] The deionized water storage tank 2 is connected to the deionized water delivery pump 26 through the eleventh water conduit 25. The deionized water delivery pump 26 can deliver deionized water. The inlet of the deionized water delivery pump is provided with a Y-type filter 27. The Y-type filter 27 can filter mechanical impurities in the medium, and can filter rust, sand in sewage, a small amount of solid particles in the liquid, etc. to protect the accessories on the equipment pipeline from wear and blockage, and can protect the normal operation of the equipment. The outlet of the deionized water delivery pump is provided with a check valve 28, and the check valve 28 is set to prevent backflow.

[0020] This system can adjust each valve accordingly according to different incoming water and different outflow water quality requirements to form a reasonable and more cost-effective water treatment process, which can significantly reduce costs, increase the service life of equipment, and reduce maintenance costs.

[0021] It is worth noting that the technical features of the multi-media filter, water pump, reducing agent addition mechanism, activated carbon adsorption device, precision filter, reverse osmosis membrane, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional selection in the field, and should not be regarded as the invention point of this utility model patent. This utility model patent will not be further elaborated.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
