Description

Technical Field

[0001] The utility model relates to the technical field of ozone water treatment, in particular to a water treatment device that generates ozone through electrolysis of water for water treatment. Background Art

[0002] Ozone is widely used in the treatment of tap water, purified water, and drinking water. Within the ozone water treatment industry, large, medium, and small ozone water generators operate by introducing filtered air or oxygen into the device. A high-voltage, high-frequency AC current is supplied to the discharge tube via a power supply system, generating ozone through a glow discharge process. The ozone mixture produced by the ozone generator is then drawn into the water to be treated via a gas-liquid mixing pump or injected into the water via a jet flow, disinfecting and sterilizing the water. Finally, the ozone is produced through a gas-liquid separation device, resulting in ozone water and exhaust gas.

[0003] The raw gas for producing ozone using existing glow discharge technology can be divided into three methods: filtered air, oxygen produced by oxygen generators, and oxygen produced by liquid oxygen tanks. All three methods have the problems of large space requirements, poor mobility, and complex supporting equipment. The complex supporting equipment also brings complex installation issues, as follows:

[0004] (1) If filtered air is used as raw gas, air treatment facilities such as air compressors, cold dryers, and adsorption dryers are required, which occupy a large area. In addition, since the air contains nitrogen, impurities such as nitrogen oxides will be produced after high-voltage discharge, affecting the purity of ozone.

[0005] (2) If oxygen production equipment is used to produce oxygen as raw gas, although nitrogen oxide impurities are reduced, it also requires the configuration of air compressors, oxygen generators and other supporting facilities, which occupy a large area.

[0006] (3) If liquid oxygen storage tanks are used to produce oxygen as raw gas, on the one hand, supporting facilities such as evaporators need to be configured, which occupies a large area. On the other hand, the safety of pressure vessels and pipelines must also be considered. Summary of the Invention

[0045] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 In some embodiments of the present invention, an ozone water treatment device is proposed, including a control system 10, a water supply pipeline 20, a water outlet pipeline 30, an ozone mixing reactor 40 and an ozone generating part.

[0047] The water supply line 20 and the water outlet line 30 are the main system pipelines of the entire ozone water treatment device. The water supply line 20 is used to pass the water to be treated into the ozone water treatment device, and the water outlet line 30 is used to discharge the treated water to the user's water supply area or other occasions. The water to be treated can be tap water, purified water, direct drinking water, or other water sources. The water supply line 20 is divided into a first water supply branch 21 and a second water supply branch 22. After entering the water supply line 20, the water to be treated is distributed in two ways.

[0048] The ozone mixing reactor 40 is used to thoroughly mix the water to be treated with ozone to achieve the effect of fully sterilizing and disinfecting the water to be treated. The water inlet of the ozone mixing reactor 40 is connected to the water outlet of the first water supply branch 21, and the water outlet of the ozone mixing reactor 40 is connected to the water outlet pipeline 30. The ozone mixing reactor 40 uses an existing high-efficiency ozone mixing reaction tank. The water to be treated enters through the water supply pipeline 20 and enters the ozone mixing reactor 40 through the first water supply branch 21. The water to be treated is thoroughly mixed with ozone by the ball ring inside the tank, achieving the effect of sterilizing and disinfecting the water to be treated, or forming ozone water with a certain concentration. After that, the water is discharged through the water outlet pipeline 30 for user use.

[0049] The ozone generating unit, which is used to generate ozone for the ozone mixing reactor 40, includes an electrolytic ozone generator 50 and an electrolytic water tank 60. The electrolytic water tank water inlet 63 is connected to the second water supply branch 22, and the electrolytic water tank water outlet 64 is connected to the electrolytic water inlet 51 of the electrolytic ozone generator 50; the electrolytic ozone generator air outlet 52 is connected to the electrolytic water tank air inlet 61, and the electrolytic water tank air outlet 62 is connected to the ozone mixing reactor air inlet 41.

[0050] The water to be treated that enters through the water supply pipe 20 enters the electrolytic water tank 60 through the second water supply branch 22 as raw water for electrolysis, and then enters the electrolytic ozone generator 50. After electrolysis in the electrolytic ozone generator 50, ozone is generated. The generated ozone passes through the electrolytic ozone generator outlet 52 and the electrolytic water tank 60 and enters the ozone mixing reactor 40 as raw gas for treating the first water to be treated.

[0051] In the ozone generating section, the electrolytic water tank 60 serves, on the one hand, to introduce a portion of the water to be treated as raw water for electrolysis of the electrolytic ozone generator 50 and to temporarily store the raw water. On the other hand, the ozone generated by electrolysis in the electrolytic ozone generator 50 is discharged through the gas outlet 52 of the electrolytic ozone generator and then enters the electrolytic water tank 60 first, and gradually accumulates in the upper part of the electrolytic water tank 60, thereby increasing the ozone pressure so that it can smoothly enter the ozone mixing reactor 40.

[0052] The ozone water treatment device in the embodiment of the present invention adopts an electrolytic ozone generator 50 to generate ozone as raw gas for water treatment. There is no need to introduce additional raw gas, which reduces the supporting air compressor, cold dryer, oxygen generator, liquid oxygen storage tank and other facilities, reduces equipment cost and reduces space occupancy; each component can be integrated inside the device to form a whole, which is convenient for the movable design of the entire device. After power is supplied, ozone can be generated to treat the water to be treated; the ozone water treatment device in the embodiment of the present invention directly generates ozone, and only hydrogen and oxygen elements participate in the reaction, and no nitrogen oxide impurities are generated.

[0053] A main water inlet valve 23 is provided on the water supply pipeline 20, which is used to manually open the water inlet; a water inlet solenoid valve 24 is provided on the first water supply branch 21, which is used to automatically adjust the opening and closing of the water inlet according to the liquid level in the ozone mixing reactor 40; an electrolysis water replenishment solenoid valve 25 is provided between the second water supply branch 22 and the electrolysis water tank inlet 63, which is used to automatically adjust the opening and closing of the electrolysis water inlet pipeline according to the liquid level in the electrolysis water tank 60.

[0054] The water outlet pipe 30 is provided with a water outlet pump 31, which is used to provide kinetic energy for the treated water or ozone water to be transported to the user's water use location; the water outlet pipe 30 is also provided with a water outlet valve 32, which is used to manually start the water outlet, and the water outlet valve 32 can also be manually adjusted to adjust the water outlet pressure to an appropriate pressure.

[0055] A water outlet pressure gauge 33 is provided on the water outlet pipe 30 for displaying the water pressure.

[0056] In some embodiments of the present invention, a pretreatment device 70 is provided on the second water supply branch 22 for pretreating the water flowing through the second water supply branch 22, thereby pretreating the raw water for electrolysis entering the electrolysis water tank 60 and the electrolytic ozone generator 50 to meet electrolyzed water standards. The pretreatment device 70 is specifically a water treatment module, such as an RO reverse osmosis module.

[0057] The top of the ozone mixing reactor 40 is connected to a drain pipe 42, which is equipped with an ozone tail gas destroyer 43. The drain pipe 42 is used to discharge the remaining ozone and oxygen mixed with water, and the ozone tail gas destroyer 43 is used to decompose the ozone discharged from the drain pipe 42 into oxygen before releasing it.

[0058] In some embodiments of the present invention, the ozone mixing reactor water inlet 44 is located at the top of the ozone mixing reactor 40, the ozone mixing reactor water outlet 45 is located at the bottom of the ozone mixing reactor 40, and the ozone mixing reactor air inlet 41 is located at the bottom of the ozone mixing reactor 40. Ozone enters through the bottom of the ozone mixing reactor 40 and countercurrently reacts with water entering from the top of the ozone mixing reactor 40 to form a reaction in the ball ring packing, thereby improving the mixing reaction effect.

[0059] A high liquid level detection switch is provided at the top of the ozone mixing reactor 40 for monitoring the high liquid level position of the liquid in the ozone mixing reactor 40; a low liquid level detection switch is provided at the bottom of the ozone mixing reactor 40 for monitoring the low liquid level position of the liquid in the ozone mixing reactor 40; by monitoring the liquid level in the ozone mixing reactor 40, it is convenient to control the liquid level in the ozone mixing reactor 40 between the high liquid level position and the low liquid level position to ensure the working reliability and safety of the ozone mixing reactor 40.

[0060] Similarly, a high liquid level detection switch is provided at the top of the electrolytic water tank 60 for monitoring the high liquid level position of the liquid in the electrolytic water tank 60; a low liquid level detection switch is provided at the bottom of the electrolytic water tank 60 for monitoring the low liquid level position of the liquid in the electrolytic water tank 60; by monitoring the liquid level in the electrolytic water tank 60, it is convenient to replenish water in the electrolytic water tank 60 in a timely manner, so that the liquid level in the electrolytic water tank 60 is between the high liquid level position and the low liquid level position, so as to ensure the reliability and safety of the electrolytic ozone reactor.

[0061] Since the electrolytic ozone generator 50 generates heat when working, in order to dissipate the heat in time and ensure the working reliability of the electrolytic ozone generator 50, in some embodiments of the present invention, the ozone water treatment device also includes a cooling device for dissipating the heat of the electrolytic ozone generator 50.

[0062] In some embodiments of the present invention, the cooling device includes a cooling water tank 80 and a radiator 90. The cooling water tank inlet 83 is connected to the second water supply branch 22, specifically connected to the outlet of the pretreatment device 70 on the second water supply branch 22, so that the water entering the cooling water tank 80 as cooling water is also a part of the untreated water after being treated by the pretreatment device 70 to reduce the TDS value of the water; the cooling water tank outlet 84 is connected to the cooling water inlet 53 of the electrolytic ozone generator 50 to introduce cooling water into the electrolytic ozone generator 50. A cooling water pump 100 is provided on the connecting pipeline between the outlet of the cooling water tank 80 and the cooling water inlet 53 of the electrolytic ozone generator 50 to drive the flow of cooling water. The cooling water outlet 54 of the electrolytic ozone generator 50 is connected to the inlet of the radiator 90.

[0063] The electrolytic water inlet 51 and the electrolytic ozone generator outlet 52 of the electrolytic ozone generator 50 are arranged on the anode side of the electrolytic ozone generator 50, and the cooling water inlet 53 and the cooling water outlet 54 of the electrolytic ozone generator 50 are arranged on the cathode side of the electrolytic ozone generator 50.

[0064] A portion of the untreated water in the second water supply branch 22 is used as cooling water, which is passed into the electrolytic ozone generator 50. The cooling water flows through the radiator 90, removing the heat generated by the electrolysis in the electrolytic ozone generator 50, effectively dissipating heat from the electrolytic ozone generator 50. On the electrolytic ozone generator 50, the cooling water inlet 53 and cooling water outlet 54 are located on the cathode side, while the electrolytic water inlet 51 and electrolytic ozone generator outlet 52 are located on the anode side. These are separated by a solid polymer electrolyte membrane within the electrolytic ozone generator 50, preventing cooling water from entering the anode side, i.e., the reaction side, and affecting the electrolysis reaction.

[0065] Furthermore, the cooling water tank 80 is provided with a cooling water tank return port 81. The water outlet of the radiator 90 is connected to the cooling water tank return port 81. Then, driven by the cooling water pump 100, the cooling water can be circulated, reducing the amount of cooling water used. The cooling water pump 100 can also increase the flow of cooling water and enhance the heat dissipation effect.

[0066] In some embodiments of the present invention, a drain port is provided on the top of the cooling water tank 80 , and the drain port is connected to the cooling drain pipe 82 for discharging hydrogen generated by electrolysis and excess cooling water.

[0067] A low liquid level detection switch is provided at the bottom of the cooling water tank 80 to monitor the low liquid level of the cooling water tank 80 so as to replenish water into the cooling water tank 80 in time.

[0068] In the case where the raw water for electrolysis entering the electrolytic water tank 60 and the cooling water entering the cooling water tank 80 both flow through the pretreatment device 70, the pretreatment device 70 is arranged on the second water supply branch 22, and the outlet pipe of the pretreatment device 70 is divided into two routes, one route is connected to the electrolytic water tank 60, and the other route is connected to the cooling water tank 80. The electrolysis water replenishment solenoid valve 25 is arranged on the connecting pipe between the pretreatment device 70 and the electrolytic water tank 60, and the cooling water tank water replenishment valve 110 is provided on the connecting pipe between the pretreatment device 70 and the cooling water tank 80, which is used for manual start-up to replenish the cooling water tank 80.

[0069] The control system 10 is used to control the operation of the ozone water treatment device and monitor its operating status. As a preferred embodiment, the control system 10 is a PLC control system. It detects the system liquid level by receiving liquid level switch signals from the ozone mixing reactor 40, electrolytic water tank 60, and cooling water tank 80. It also controls the water inlet solenoid valve 24, the water outlet pump 31, the electrolytic water replenishment solenoid valve 25, the cooling water pump 100, and the power supply to the electrolytic ozone generator 50 to ensure stable operation of the device.

[0070] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
