Description

Technical Field

[0001] The utility model relates to an underwater ozone generating device, belonging to the technical field of environmental protection equipment. Background Art

[0002] Ozone has a strong oxidizing ability and can kill bacteria in water and decompose pollutants in water. After ozone reduction, it can also increase the amount of dissolved oxygen in water and effectively improve the water quality. For example, after water is treated by conventional water purification processes such as activated carbon, ultrafiltration, and reverse osmosis, ozone is injected to deeply remove bacteria and other harmful substances in the water.

[0003] At present, when ozone is used for water disinfection, the ozone generator is usually installed in the machine room around the water tank along with other electrical equipment. The generated ozone needs to be transported through pipelines and injected into the water in the water tank. During the application process, it was found that the ozone power supply, high-voltage transformer, and ozone generator in the current ozone generator are usually integrated together; because ozone is unstable, part of the ozone will decompose during transportation in the pipeline, resulting in ozone transportation loss; in addition, during the working process, the ozone generator electrode needs to be cooled by cooling water to cool the electrode assembly.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] It should be noted that many specific details are described in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0024] like Figure 1 and Figure 2 As shown in the figure, the underwater ozone generating device provided by the present invention comprises a switching power supply module 100 and an oxygen supply module 200 arranged outside the water body, and a high-voltage transformer 300 and an ozone generating tube 410 arranged in the water body.

[0025] The oxygen supply module 200 usually uses an oxygen concentrator, and the oxygen generated by the oxygen concentrator is stored in an oxygen tank. The high-voltage transformer 300 is placed in an insulating waterproof box 310, and the switching power supply module 100 is connected to the high-voltage transformer 300 through an insulating waterproof cable 500.

[0026] The switching power supply module 100 is usually arranged in a machine room around the water tank 1. The switching power supply module 100 provides a medium-frequency current signal, which is transmitted to the underwater high-voltage transformer 300 through an insulated waterproof cable 500. The medium-frequency current signal is boosted by the high-voltage transformer 300 and then used by the ozone generator.

[0027] Specifically, the ozone generating tube 410 is made of quartz or ceramic, and a conductive mesh ground electrode 420 in contact with the water body is provided on the outside of the ozone generating tube 410 . The upper part of the ozone generating tube 410 is sealed and connected to the insulating waterproof box 310 , and a one-way exhaust valve 600 is installed at the lower part of the ozone generating tube 410 .

[0028] An internal high-voltage electrode 430 is provided inside the ozone generating tube 410 , the upper part of the internal high-voltage electrode 430 is connected to the high-voltage transformer 300 , an air intake channel 431 is provided inside the internal high-voltage electrode 430 , and the air intake channel 431 is connected to the oxygen supply module 200 through the air intake pipe 700 .

[0029] An outer high-voltage electrode 440 is arranged outside the inner high-voltage electrode 430. The lower end of the outer high-voltage electrode 440 is closed with a bottom wall and the upper end is open. The outer high-voltage electrode 440 is connected to the inner high-voltage electrode 430 through a plurality of conductive sheets 450 arranged at intervals. A gap D is arranged between the lower end of the air inlet channel 431 of the inner high-voltage electrode 430 and the bottom wall of the outer high-voltage electrode 440. The cavity between the outer high-voltage electrode 440 and the ozone generating tube 410 forms a plasma discharge gap 460. The gap D is used for the airflow discharged from the air inlet channel 431 of the inner high-voltage electrode 430 to enter the gap between the inner high-voltage electrode 430 and the outer high-voltage electrode 440 after reversing, and the airflow is discharged from the gap between the inner high-voltage electrode 430 and the outer high-voltage electrode 440 and then enters the plasma discharge gap 460.

[0030] When working, the oxygen supply module 200 delivers oxygen flow of a certain pressure to the inner high-voltage electrode 430 through the air intake pipe 700. The oxygen flow is discharged from the lower end of the air intake channel 431 of the inner high-voltage electrode 430, and flows upward in the opposite direction after being blocked by the bottom wall of the outer high-voltage electrode 440, and then enters the plasma discharge gap 460 between the outer high-voltage electrode 440 and the ozone generating tube 410. In the process of passing through the plasma discharge gap 460, part of the oxygen is converted into ozone. The airflow mixed with ozone can open the one-way exhaust valve 600 in one direction, so that the ozone airflow is injected into the water body. When not working, the one-way exhaust valve 600 is closed to prevent water backflow.

[0031] The utility model arranges the switch power supply module on the ground, and arranges the high-voltage transformer and the ozone generating tube in the water body, so that the generated ozone can directly enter the water body, and compared with the traditional ozone generator which adopts pipeline transportation and pressurizes the ozone into the water body, the transportation loss of the ozone is avoided.

[0032] Moreover, the ozone generating tube is set in the water body, and the heat generated during operation directly heats the water body, eliminating the electrode water cooling component, which is more energy-saving. At the same time, it can also increase the water temperature, thereby improving the oxidation and decomposition efficiency of ozone.

[0033] Preferably, the plasma discharge gap 460 between the ozone generating tube 410 and the outer high voltage electrode 440 is filled with a conductive mesh 470 to increase the discharge area.

[0034] In one specific embodiment, the underwater ozone generating device provided by the utility model further includes an upper fixing seat 810 and a lower fixing seat 820 respectively arranged at the top and bottom of the ozone generating tube 410, and the upper fixing seat 810 and the lower fixing seat 820 are both provided with mounting holes 830. After the upper fixing seat 810 and the lower fixing seat 820 are fastened and connected by tension bolts 840, the upper port of the ozone generating tube 410 is sealedly connected to the bottom of the mounting hole of the upper fixing seat 810, and the lower port of the ozone generating tube 410 is sealedly connected to the top of the mounting hole of the lower fixing seat 820, and the one-way exhaust valve 600 is arranged in the mounting hole of the lower fixing seat 820.

[0035] Furthermore, an airflow distribution head 900 is installed at the bottom of the mounting hole of the lower fixing seat 820, and a plurality of air outlet pipes 910 are arranged on the airflow distribution head 900. The airflow mixed with ozone enters the airflow distribution head 900 from the ozone generating pipe 410, and then dispersedly sprayed into the water body through the air outlet pipes 910, so that the ozone is fully mixed into the water body, and the organic matter in the water body is oxidized and decomposed, so that the water body is purified.

[0036] The insulating waterproof box 310 is sealed and connected to the top of the mounting hole of the upper fixing seat 810 .

[0037] Specifically, sealing rings should be provided on the connecting surfaces including the connecting surface between the internal high-voltage electrode and the upper fixing seat mounting hole, the connecting surface between the ozone generating tube and the upper fixing seat mounting hole, the connecting surface between the ozone generating tube and the lower fixing seat mounting hole, and the connecting surface between the airflow distribution head and the lower fixing seat mounting hole.

[0038] The upper fixing seat mounting hole and the lower fixing seat mounting hole can be set as stepped holes and internal threads can be processed as needed, so as to be conveniently connected with various structures.

[0039] The underwater ozone generating device provided by the utility model is installed at a lower position of a water body through a bracket when in use, and the generated ozone directly enters the water body, thereby avoiding the transport loss of the ozone.

[0040] If the high-voltage transformer 300 is set in the machine room, the high-voltage high-frequency current signal needs to be transmitted to the underwater ozone generator 400 through the insulated waterproof cable 500, which causes radiation loss of high-voltage transmission. In the present invention, the high-voltage transformer 300 is set inside the waterproof box 310 in the water body, and the medium-frequency current signal provided by the switching power supply module 100 is transmitted to the high-voltage transformer 300 through the insulated waterproof cable 500, which reduces the radiation loss of cable transmission.
