Description

Technical Field

[0001] This utility model relates to a purified water distribution system for ozone disinfection. Background Technology

[0002] Currently, purified water, which meets specific quality standards after impurities are removed from water, is widely used in pharmaceutical, chemical, and other fields. Pharmaceutical companies need to periodically disinfect the purified water in their distribution systems during production. Some companies choose to use high-temperature steam and heat exchangers to heat and disinfect the purified water in the system. However, disinfecting purified water in the system by heating it with high-temperature steam requires the generation of large amounts of high-temperature steam, consuming a significant amount of energy, leading to high energy consumption and increased energy costs, which is detrimental to energy conservation and emission reduction. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an ozone disinfection purified water distribution system that can generate ozone to disinfect purified water, reduce energy consumption, save energy costs, and is conducive to energy conservation and emission reduction.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a purified water distribution system for ozone disinfection, including a storage tank, a raw water pump, an ozone generator, a water delivery pipeline, a return water pipeline, a connecting pipeline, a first ozone destroyer, and an ozone concentration detector;

[0005] The storage tank is used to receive and store purified water;

[0006] The inlet of the raw water pump is connected to the outlet of the storage tank, the outlet of the raw water pump is connected to the water delivery pipeline, the water delivery pipeline is connected to the connecting pipeline, the connecting pipeline is connected to the return water pipeline, and the return water pipeline is connected to the return water outlet of the storage tank. The raw water pump is used to pump purified water so that the purified water flows from the outlet of the storage tank through the raw water pump, the water delivery pipeline, the connecting pipeline and the return water pipeline in sequence, and then flows back to the storage tank from the return water outlet of the storage tank.

[0007] The inlet of the ozone generator is connected to the water supply pipeline, and the outlet of the ozone generator is connected to the air inlet of the storage tank.

[0008] The first ozone destroyer is connected in the return water pipeline;

[0009] The ozone concentration detector is connected in the return water pipeline and is connected to the outlet of the first ozone destroyer.

[0010] Furthermore, a first valve is connected between the inlet of the ozone generator and the water supply pipeline, and a second valve is connected between the outlet of the ozone generator and the air inlet of the storage tank.

[0011] Furthermore, the ozone disinfection purified water distribution system also includes a breather and a second ozone destroyer. The breather is connected to the storage tank and is used to balance the pressure inside the storage tank. The second ozone destroyer is connected to the breather.

[0012] Furthermore, the ozone disinfection purified water distribution system also includes a water tank and a first sampling valve. The first sampling valve is connected in the water supply pipeline and located above the water tank. The first sampling valve is used to open so that the purified water in the water supply pipeline flows from the first sampling valve into the water tank for sampling.

[0013] Furthermore, the ozone disinfection purified water distribution system also includes a second sampling valve and a third sampling valve. Both the second and third sampling valves are connected in the return water pipeline and are located above the water tank. The second sampling valve is used to open so that the purified water in the return water pipeline flows into the water tank for sampling. The third sampling valve is used to open so that the purified water in the return water pipeline flows into the water tank for sampling.

[0014] Furthermore, in the return water pipeline, both the first ozone destroyer and the ozone concentration detector are located between the second sampling valve and the third sampling valve.

[0015] Furthermore, the ozone disinfection purified water distribution system also includes an emptying pipe connected to the outlet of the storage tank, and the outlet of the water tank is connected to the emptying pipe.

[0016] Furthermore, a first control valve is connected to the inlet of the raw water pump, a second control valve is connected to the drain pipe, and a third control valve is connected between the outlet of the water tank and the drain pipe.

[0017] Furthermore, the connecting pipeline is equipped with multiple water supply points.

[0018] Furthermore, the ozone disinfection purified water distribution system also includes an inlet pipe connected to the storage tank, and an inlet valve is connected in the inlet pipe.

[0019] After adopting the above technical solution, under the pumping action of the raw water pump, the purified water in the storage tank flows from the outlet of the storage tank through the raw water pump and into the water delivery pipeline. A portion of the purified water in the water delivery pipeline flows into the ozone generator, which electrolyzes the purified water to generate ozone. The generated ozone flows into the storage tank from the air inlet, thereby disinfecting the purified water and killing microorganisms in it, ensuring the water quality. Simultaneously, most of the purified water pumped into the water delivery pipeline flows sequentially through the connecting pipeline and the return water pipeline, then returns to the storage tank from the return water outlet, forming a circulation. During the circulation of purified water, ozone is carried to disinfect the entire system. The first ozone destroyer decomposes the ozone in the return water pipeline, ensuring that the ozone concentration in the purified water returning to the storage tank does not exceed the standard. The ozone concentration detector can monitor the ozone concentration in the return water pipeline online. In this embodiment, ozone generated by an ozone generator is used to disinfect purified water, eliminating the need to prepare large amounts of high-temperature steam. This significantly reduces energy consumption, saves energy costs, and is beneficial for energy conservation and emission reduction. Attached Figure Description

[0024] The storage tank 1 is used to connect to and store purified water;

[0025] The inlet of the raw water pump 2 is connected to the outlet of the storage tank 1, the outlet of the raw water pump 2 is connected to the water delivery pipeline 4, the water delivery pipeline 4 is connected to the connecting pipeline 6, the connecting pipeline 6 is connected to the return water pipeline 5, and the return water pipeline 5 is connected to the return water outlet of the storage tank 1. The raw water pump 2 is used to pump purified water so that the purified water flows from the outlet of the storage tank 1 through the raw water pump 2, the water delivery pipeline 4, the connecting pipeline 6 and the return water pipeline 5 in sequence, and then flows back to the storage tank 1 from the return water outlet of the storage tank 1.

[0026] The inlet of the ozone generator 3 is connected to the water supply pipeline 4, and the outlet of the ozone generator 3 is connected to the air inlet of the storage tank 1.

[0027] The first ozone destroyer 7 is connected in the return water pipe 5;

[0028] The ozone concentration detector 8 is connected in the return water pipe 5 and is connected to the outlet of the first ozone destroyer 7.

[0029] Specifically, under the pumping action of the raw water pump 2, the purified water in the storage tank 1 flows from the outlet of the storage tank 1 through the raw water pump 2 and then into the water delivery pipeline 4. A portion of the purified water in the water delivery pipeline 4 flows into the ozone generator 3. The ozone generator 3 can electrolyze the purified water to generate ozone. The generated ozone flows into the storage tank 1 from the air inlet of the storage tank 1 to disinfect the purified water, thereby killing microorganisms in the purified water and ensuring the water quality. At the same time, most of the purified water pumped by the raw water pump 2 into the water delivery pipeline 4 flows sequentially through the connecting pipeline 6 and the return water pipeline 5 and then flows back into the storage tank 1 from the return water inlet, thus forming a circulating flow. During the purified water circulation process, ozone is carried to disinfect the entire system. The first ozone destroyer 7 can decompose the ozone in the return water pipe 5, thereby ensuring that the ozone concentration in the purified water flowing back to the storage tank 1 from the return water pipe 5 does not exceed the standard. The ozone concentration detector 8 can detect the ozone concentration in the return water pipe 5 online. In this embodiment, the ozone generated by the ozone generator 3 disinfects the purified water without the need to prepare a large amount of high-temperature steam, thus greatly reducing energy consumption, saving energy costs, and contributing to energy conservation and emission reduction.

[0030] like Figure 1 As shown, a first valve 9 is connected between the inlet of the ozone generator 3 and the water supply pipeline 4, and a second valve 10 is connected between the outlet of the ozone generator 3 and the air inlet of the storage tank 1. Specifically, the first valve 9 and the second valve 10 need to be opened when the ozone generator 3 is working. The first valve 9 can be a pneumatic valve, and the second valve 10 can be a manual valve.

[0031] like Figure 1 As shown, the ozone disinfection purified water distribution system may further include a respirator 11 and a second ozone destructor 12. The respirator 11 is connected to the storage tank 1 and is used to balance the pressure inside the storage tank 1. The second ozone destructor 12 is connected to the respirator 11. Specifically, the second ozone destructor 12 can decompose the ozone discharged into the air from the respirator 11, thereby ensuring that the ozone content in the discharged air does not exceed the standard. The specific structures of the ozone generator 3, the first ozone destructor 7, the second ozone destructor 12, the ozone concentration detector 8, and the respirator 11 are all prior art well known to those skilled in the art, and will not be described in detail in this embodiment.

[0032] like Figure 1 As shown, the ozone disinfection purified water distribution system may further include a water tank 13 and a first sampling valve 14. The first sampling valve 14 is connected in the water supply pipeline 4 and located above the water tank 13. The first sampling valve 14 is used to open so that the purified water in the water supply pipeline 4 flows from the first sampling valve 14 into the water tank 13 for sampling, thereby enabling water quality testing by taking samples from the water tank 13.

[0033] like Figure 1 As shown, the ozone disinfection purified water distribution system may further include a second sampling valve 15 and a third sampling valve 16. Both the second sampling valve 15 and the third sampling valve 16 are connected in the return water pipeline 5. Both the second sampling valve 15 and the third sampling valve 16 are located above the water tank 13. The second sampling valve 15 is used to open so that the purified water in the return water pipeline 5 flows into the water tank 13 for sampling. The third sampling valve 16 is used to open so that the purified water in the return water pipeline 5 flows into the water tank 13 for sampling.

[0034] like Figure 1 As shown, in the return water pipeline 5, the first ozone destroyer 7 and the ozone concentration detector 8 are both located between the second sampling valve 15 and the third sampling valve 16. Specifically, opening the second sampling valve 15 and the third sampling valve 16 allows purified water from different locations in the return water pipeline 5 to flow into the water tank 13, thereby enabling water quality testing of purified water samples from different locations in the return water pipeline 5.

[0035] like Figure 1 As shown, the ozone disinfection purified water distribution system may further include an emptying pipe 17 connected to the outlet of the storage tank 1, and the outlet of the water tank 13 is connected to the emptying pipe 17.

[0036] like Figure 1As shown, the inlet of the raw water pump 2 is connected to a first control valve 18, the drain pipe 17 is connected to a second control valve 19, and the outlet of the water tank 13 is connected to the drain pipe 17 via a third control valve 20. Specifically, during normal operation, the first control valve 18 is opened and the second control valve 19 is closed. When it is necessary to drain the purified water in the storage tank 1, the second control valve 19 is opened and the first control valve 18 is closed. When it is necessary to drain the water in the water tank 13, the third control valve 20 is opened.

[0037] like Figure 1 As shown, the connecting pipe 6 may be equipped with multiple water points 21.

[0038] like Figure 1 As shown, the ozone disinfection purified water distribution system may further include an inlet pipe 22 connected to the storage tank 1, and an inlet valve 23 is connected in the inlet pipe 22; specifically, the storage tank 1 is connected to external purified water and stores purified water through the inlet pipe 22.

[0039] In summary, under the pumping action of the raw water pump 2, the purified water in the storage tank 1 flows from the outlet of the storage tank 1 through the raw water pump 2 and then into the water delivery pipeline 4. A portion of the purified water in the water delivery pipeline 4 flows into the ozone generator 3. The ozone generator 3 can electrolyze the purified water to generate ozone. The generated ozone flows into the storage tank 1 from the air inlet of the storage tank 1 to disinfect the purified water, thereby killing microorganisms in the purified water and ensuring the water quality. At the same time, most of the purified water pumped by the raw water pump 2 into the water delivery pipeline 4 flows sequentially through the connecting pipeline 6 and the return water pipeline 5 and then flows back into the storage tank 1 from the return water inlet, thus forming a circulating flow. During the purified water circulation process, ozone is carried to disinfect the entire system. The first ozone destroyer 7 can decompose the ozone in the return water pipe 5, thereby ensuring that the ozone concentration in the purified water flowing back to the storage tank 1 from the return water pipe 5 does not exceed the standard. The ozone concentration detector 8 can detect the ozone concentration in the return water pipe 5 online. In this embodiment, the ozone generated by the ozone generator 3 disinfects the purified water without the need to prepare a large amount of high-temperature steam, thus greatly reducing energy consumption, saving energy costs, and contributing to energy conservation and emission reduction.
