Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water treatment, and in particular to a purified water distribution system. Background Technology
[0002] Existing purified water distribution systems typically include storage tanks to store purified water produced during production, which is then pumped to usage points in the workshop via transfer pumps. To reduce the risk of microbial growth, unused purified water in the system is continuously circulated. Heaters are usually installed in the circulation lines to heat the water for pasteurization.
[0003] However, this traditional purified water distribution system has several significant drawbacks. First, the pasteurization process consumes a large amount of industrial steam, leading to a substantial increase in operating costs. This not only increases the economic burden on enterprises but may also affect overall production efficiency. Second, when purified water is not used at the downstream end, it continuously circulates in the pipeline, where the rate of microbial growth gradually accelerates. Although pasteurization can kill microorganisms, it cannot remove their dead cells. This results in a gradual increase in the organic matter content of the purified water, which in turn causes its conductivity to rise continuously. Ultimately, the quality of the purified water may deteriorate to an unusable level, severely impacting the production process and product quality. Utility Model Content
[0004] The purpose of this invention is to provide a purified water distribution system to reduce the operating cost and conductivity of purified water and improve the water quality.
[0005] To solve the above-mentioned technical problems, this utility model provides a purified water distribution system.
[0006] The purified water distribution system of this utility model includes a water storage tank, a delivery pump, and a circulation pipeline;
[0007] The delivery pump is connected to the circulation pipeline and is used to pump the purified water in the delivery pump to the circulation pipeline;
[0008] The water storage tank is provided with a first water inlet, a second water inlet and a water outlet. The circulation pipeline has a water inlet end and a water outlet end. The water outlet is connected to the water inlet end. The first water inlet is connected to the water outlet end. The second water inlet is used to replenish water to the water storage tank.
[0009] A water intake node is provided on the circulation pipeline;
[0010] The circulation pipeline is also equipped with an ultraviolet sterilizer, an ion exchange column, and a sterilization filter in sequence.
[0011] Furthermore, the ultraviolet sterilizer, the ion exchange column, and the sterilization filter are located upstream of the water intake node.
[0012] Furthermore, the ultraviolet sterilizer is a flow-through ultraviolet sterilizer.
[0013] Furthermore, the flow-through ultraviolet sterilizer is equipped with a medium-pressure ultraviolet lamp.
[0014] Furthermore, the delivery pump is located between the water storage tank and the ultraviolet sterilizer.
[0015] Furthermore, the water intake node includes a water intake pipeline and a water intake valve for controlling the opening or closing of the water intake pipeline. One end of the water intake pipeline is connected to the circulation pipeline, and the other end is provided with a connector.
[0016] Furthermore, the water storage tank is equipped with a spray ball, and the first water inlet is connected to the spray ball. The spray ball is used to spray the purified water entering the first water inlet onto the inner wall of the water storage tank.
[0017] Furthermore, the portion of the circulation pipeline upstream of the delivery pump is equipped with a first valve and a drainage branch pipeline, the drainage branch pipeline is equipped with a second valve, and the first valve is located downstream of the connection between the drainage branch pipeline and the circulation pipeline.
[0018] Furthermore, a breather is connected to the water storage tank, which is used to balance the air pressure inside the water storage tank.
[0019] Furthermore, the circulation pipeline is also equipped with a sampling valve, a conductivity meter, and a wastewater discharge pipeline.
[0020] Compared with the prior art, the present invention has at least the following beneficial effects:
[0021] In operation, this application sequentially installs an ultraviolet sterilizer, an ion exchange column, and a sterilization filter in the circulation pipeline. The ultraviolet sterilizer kills and inhibits microbial growth, reducing the total organic carbon content in the purified water. The ion exchange column replaces calcium and magnesium ions in the purified water, reducing its conductivity and creating a low-nutrient environment to inhibit microbial growth. The sterilization filter removes the very small amount of dead microorganisms remaining upstream. These three components work synergistically to effectively prevent microbial growth and increased conductivity during the circulation process. Furthermore, the more cycles the purified water undergoes, the better its quality. Compared to existing pasteurization methods using heaters, this application consumes less energy and is less prone to long-term circulation that degrades water quality. Therefore, this purified water distribution system ensures water quality while reducing operating costs. Attached Figure Description

It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0033] The following is in conjunction with the instruction manual appendix. Figure 1 This paper introduces the purified water distribution system of this utility model.
[0034] In one embodiment, such as Figure 1As shown, the purified water distribution system of this application includes a water storage tank 10, a transfer pump 20, and a circulation pipeline 30. The transfer pump 20 is connected to the circulation pipeline 30 and is used to pump purified water from the water storage tank 10 into the circulation pipeline 30. The water storage tank 10 is provided with a first inlet 11, a second inlet 12, and an outlet 13. The circulation pipeline 30 has an inlet end and an outlet end. The outlet 13 is connected to the inlet end, the first inlet 11 is connected to the outlet end, and the second inlet 12 is used to replenish water to the water storage tank 10. The circulation pipeline 30 is provided with a water intake node 22, through which purified water can be distributed to the required location. The circulation pipeline 30 is also sequentially provided with an ultraviolet sterilizer 31, an ion exchange column 32, and a sterilization filter 33.
[0035] In use, this application sequentially installs an ultraviolet sterilizer 31, an ion exchange column 32, and a sterilization filter 33 on the circulation pipeline 30. The ultraviolet sterilizer 31 kills microorganisms, inhibits their growth, and reduces the total organic carbon content in the purified water. The ion exchange column 32 replaces calcium and magnesium ions in the purified water, reducing its conductivity and creating a low-nutrient environment to inhibit microbial growth. The sterilization filter 33 filters out the very few microbial remains left upstream. These three components work synergistically to effectively prevent microbial growth and increased conductivity during the circulation process. Furthermore, the more cycles the purified water undergoes, the better its quality. Compared to existing pasteurization methods using heaters, this application consumes less energy and is less prone to long-term circulation that deteriorates water quality. Therefore, this purified water distribution system ensures water quality while reducing operating costs.
[0036] In one embodiment, the ion exchange column 32 is provided with a sodium-type cation exchange resin. Alternatively, a weakly acidic cation exchange resin can be used to replace calcium and magnesium ions.
[0037] In one embodiment, the purified water distribution system further includes a water replenishment pipeline 34, which is connected to the second water inlet 12 to replenish water to the water storage tank 10.
[0038] In one embodiment, the ultraviolet sterilizer 31, the ion exchange column 32, and the sterilization filter 33 are located upstream of the water intake node 22.
[0039] Specifically, the ultraviolet sterilizer 31 kills microorganisms by irradiating with ultraviolet light, the ion exchange column 32 removes ions and impurities from the water through ion exchange, and the sterilization filter 33 further removes microorganisms through physical filtration. These devices work together to ensure that the water quality at the water intake point 22 meets the requirements.
[0040] Therefore, by treating the water before the water intake node 22, this application ensures that all water intake is treated, which can effectively reduce the growth of microorganisms and thus solve the problem of microorganism growth in the circulation pipeline 30.
[0041] In one embodiment, the ultraviolet sterilizer 31 is a flow-through ultraviolet sterilizer 31. In other embodiments, an immersion ultraviolet sterilizer 31 may also be used.
[0042] Specifically, the flow-through UV sterilizer 31 can be equipped with medium-pressure UV lamps. These lamps provide higher UV intensity and a wider wavelength range, thereby improving sterilization efficiency. As a preferred embodiment, the use of medium-pressure UV lamps allows UV light to penetrate the cell walls of microorganisms more effectively, destroying their DNA structure and achieving better sterilization results. Furthermore, the sterilization effect can be further optimized by adjusting the power and number of medium-pressure UV lamps. For example, the UV coverage area can be increased by increasing the number of lamps, or the lamp power can be adjusted to adapt to different water quality and flow conditions.
[0043] In one embodiment, the delivery pump 20 is located between the water storage tank 10 and the ultraviolet sterilizer 31.
[0044] Specifically, the placement of the transfer pump 20 ensures that the purified water flowing from the storage tank 10 is pumped by the transfer pump 20 before entering the ultraviolet sterilizer 31. This design not only guarantees the stability and continuity of the water flow but also helps improve the sterilization efficiency of the ultraviolet sterilizer 31. The stable water flow allows the ultraviolet light to evenly irradiate every part of the water, thereby killing microorganisms more effectively.
[0045] In a preferred embodiment, the transfer pump 20 can be of various types, such as centrifugal pumps or positive displacement pumps. Preferably, a horizontal centrifugal pump can be used to adapt to different flow and pressure requirements. The control of the transfer pump 20 can also be achieved through an automated system to ensure the stability and continuity of the water flow. Furthermore, the material selection for the transfer pump 20 should also take into account corrosion resistance and durability to ensure long-term stable operation.
[0046] In one embodiment, the water intake node 22 includes a water intake pipeline and a water intake valve for controlling the opening or closing of the water intake pipeline. One end of the water intake pipeline is connected to the circulation pipeline 30, and the other end is provided with a connector.
[0047] Specifically, the design of the water intake pipeline enables it to effectively connect the circulation pipeline 30 and the water intake point, while the water intake valve controls the opening or closing of the water intake pipeline, thereby achieving precise control and distribution of purified water.
[0048] In a preferred embodiment, the water intake valve can be an electric valve or a pneumatic valve, and the opening and closing of the water intake pipeline can be achieved through remote control or an automatic control system. Furthermore, the connectors of the water intake pipeline can be designed as quick-connect couplings to facilitate rapid connection or disconnection when needed, improving system flexibility and operational efficiency.
[0049] In one embodiment, the water storage tank 10 is provided with a spray ball 14, and the first water inlet 11 is connected to the spray ball 14. The spray ball 14 is used to spray the purified water entering the first water inlet 11 onto the inner wall of the water storage tank 10.
[0050] Specifically, the design of the spray ball 14 allows purified water to be sprayed evenly onto the inner wall of the water storage tank 10, ensuring uniform distribution of purified water within the tank and reducing its residence time on the inner wall, thereby lowering the risk of microbial growth. As a preferred embodiment, the spray ball 14 can have a porous structure, allowing purified water to be sprayed evenly through multiple small holes, further improving the spraying effect. Furthermore, the position and angle of the spray ball 14 can be adjusted according to the internal structure of the water storage tank 10 to ensure that purified water covers all parts of the inner wall of the tank.
[0051] In one embodiment, the portion of the circulation pipeline 30 upstream of the delivery pump 20 is provided with a first valve 35 and a drainage branch pipeline 36, a second valve 37 is provided on the drainage branch pipeline 36, and the first valve 35 is located downstream of the connection between the drainage branch pipeline 36 and the circulation pipeline 30.
[0052] Specifically, when it is necessary to drain the residual water in the water storage tank 10 to reduce the accumulation of microorganisms, the first valve 35 is closed and the second valve 37 is opened, and the residual water will be discharged from the drainage branch pipe 36. During normal use, the first valve 35 is opened and the second valve 37 is closed.
[0053] A third valve 38 is also installed downstream of the transfer pump 20. When the transfer pump 20 malfunctions, closing the first valve 35 and the third valve 38 can isolate the water in the circulation pipeline 30 from the transfer pump 20, thereby facilitating the maintenance and replacement of the transfer pump 20. The first valve 35, the second valve 37, and the third valve 38 are diaphragm valves.
[0054] In addition, the drainage branch pipe 36 can be designed to be detachable for regular cleaning and maintenance, ensuring the long-term stable operation of the system.
[0055] In one embodiment, a breather 15 is connected to the water tank 10, and the breather 15 is used to balance the air pressure inside the water tank 10.
[0056] Specifically, the respirator 15 regulates the air pressure within the water tank 10 to ensure it remains at a stable level, preventing structural damage to the water tank 10 or a decline in purified water quality due to pressure imbalance. As a preferred embodiment, the respirator 15 can employ an automatic regulating valve that automatically opens or closes to maintain pressure balance by sensing pressure changes within the water tank 10. Furthermore, the respirator 15 can be equipped with a pressure sensor and a control unit for more precise pressure regulation.
[0057] In one embodiment, the circulation pipeline 30 is also equipped with a sampling valve 39, a conductivity meter 40, and a wastewater discharge pipeline 41.
[0058] Specifically, the wastewater discharge pipeline is located downstream of the conductivity meter 40. The sampling valve 39 is used to collect purified water samples from the circulation pipeline 30 for quality testing. The conductivity meter 40 is used to detect the conductivity of the purified water, reflecting changes in water quality. When the conductivity meter 40 detects an increase in conductivity and the water sample obtained by the sampling valve 39 is unqualified, the unqualified purified water in the circulation pipeline 30 is discharged from the system via the wastewater discharge pipeline, thereby preventing the problem of increased conductivity caused by the accumulation of microbial remains.
[0059] In a preferred embodiment, the wastewater discharge pipeline can be set to automatic control, automatically activating the discharge function when the conductivity exceeds a preset threshold and the water sample obtained from sampling valve 39 is unqualified. Furthermore, the wastewater discharge pipeline can also be connected to an external treatment system for further treatment of the discharged wastewater, reducing environmental pollution.
[0060] In addition, a pressure gauge 42 and a flow meter 43 are also installed on the circulation pipeline 30. The pressure gauge 42 is used to monitor the water pressure in the circulation pipeline 30 in real time to ensure stable system operation. The flow meter 43 is used to monitor the flow rate of purified water to ensure accurate control of water flow.
[0061] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
