[0029] The present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, the ozone production device includes an electrolytic cell 1, a hydrogen separation tank 2, an oxygen separation tank 3, a circulation pipeline 4, a drying pipeline 5, an oxygen drying tank 6, an oxygen booster pump 7, an oxygen storage tank 8 and an ozone generator 9. In the figure, the cathode of the electrolytic cell 1 is connected to the upper part of the hydrogen separation tank 2 through a cathode air inlet pipe 101, and the anode of the electrolytic cell 1 is connected to the upper part of the oxygen separation tank 3 through an anode air inlet pipe 102. The gas-liquid mixture of hydrogen and alkali liquid produced by the cathode enters the hydrogen separation tank 2 through the cathode air inlet pipe 101, and the gas-liquid mixture of oxygen and alkali liquid produced by the anode enters the oxygen separation tank 3 through the anode air inlet pipe 102.

[0031] In this embodiment, a voltage and current detector 10 is also included. The voltage and current detector 10 is used to detect the voltage and current values ​​of the electrolyzer 1. The voltage and current detector 10 adopts an existing model or device, such as the MIK-HRI model. Among them, the power of the oxygen production power supply system is 7kw220V, 50HZ. The power supply system is divided into two routes. One route is used for the electrolyzer system. The system undergoes a water electrolysis reaction to produce hydrogen and oxygen, the hydrogen is exhausted, and the oxygen is collected for the production of ozone. At the same time, the system displays the corresponding DC current and voltage when the electrolyzer system reacts, and is linked to the pressure sensor of the oxygen storage tank. The pressure sensor controls the opening and closing of the power supply of the electrolyzer system. One route is used for the ozone system. The system undergoes a process of oxygen conversion into ozone. The system displays the current and voltage when the ozone generator is working.

[0032] In the figure, the circulation pipeline 4 includes a balance pipe 401, an alkali liquid circulation pump 402, a reflux pipe 403, a drain pipe 404 and a drain valve 405. The two ends of the balance pipe 401 connect the bottom of the hydrogen separation tank 2 and the oxygen separation tank 3. The middle part of the balance pipe 401 is connected to the inlet of the alkali liquid circulation pump 402 through a three-way valve. The outlet of the alkali liquid circulation pump 402 is divided into two paths. One path of the outlet of the alkali liquid circulation pump 402 is connected to the internal cavity of the electrolytic cell 1 through the reflux pipe 403, and the other path of the outlet of the alkali liquid circulation pump 402 is connected to the drain tank through the drain pipe 404. A drain valve 405 is provided on the drain pipe 404.

[0033] It should be noted that the electrolyzer is divided into positive and negative electrodes, which will produce hydrogen and oxygen accordingly. Through the alkaline electrolyzer, alkali solution is introduced into the electrolyzer and direct current is passed to produce gas, hydrogen is produced along the way, and enters the hydrogen separator system through the hydrogen outlet pipeline in a gas-liquid mixed state. Oxygen is produced along the way, and enters the hydrogen-oxygen separator system through the oxygen outlet pipeline in a gas-liquid mixed state, with the liquid sinking and the gas rising.

[0034] In the figure, the oxygen separation tank 3 is connected to the oxygen drying tank 6 through the drying pipeline 5. The oxygen dried by the oxygen drying tank 6 is then transported to the oxygen storage tank 8 through the oxygen booster pump 7. The oxygen storage tank 8 is connected to the ozone generator 9 through the pipeline. The ozone generator 9 converts the dry oxygen in the oxygen storage tank 8 into ozone.

[0035] In this embodiment, a water supply port 201 is provided on the top of the hydrogen separation tank 2, and a liquid level meter 202 is provided on the outside of the hydrogen separation tank 2. A liquid level meter is provided on the outside of the oxygen separation tank 3.

[0036] In the figure, the drying pipeline 5 includes a first drying passage 501 and a second drying passage 502, and the number of oxygen drying tanks 6 is two, wherein: the top outlet of the oxygen separation tank 3 is divided into two paths through a two-phase valve 503, and the two paths are connected to the inlet of the independent oxygen drying tank 6 through the first drying passage 501 and the second drying passage 502 respectively, and the outlet of each oxygen drying tank 6 is then merged into one path through a two-phase valve 503 and connected to the oxygen booster pump 7.

[0037] It should be noted that the hydrogen from the electrolyzer system enters the hydrogen separator through the hydrogen pipeline, the liquid sinks, the gas rises and is emptied or enters the hydrogen storage device. At the same time, because the electrolysis of water to produce oxygen only consumes pure water, pure water is regularly added through the liquid inlet pipe above the hydrogen separator to ensure the continuous electrolysis reaction of the electrolyzer. The sinking liquid is mixed with the alkali solution at the bottom of the separator, and the liquid level is kept balanced through the balance pipe between the two separators. At the same time, the alkali solution at the bottom of the separator and the alkali solution in the electrolyzer will be circulated alternately through the alkali solution circulation pump. Oxygen enters the oxygen separator system through the oxygen pipeline, and after gas-liquid separation, the liquid sinks and the gas rises and enters the two-way oxygen drying tank. When one oxygen dryer is working, the other is closed to fully absorb the moisture in the oxygen. When the water absorption of one oxygen drying tank reaches the limit, the working oxygen dryer is switched through the two-phase valve between the oxygen separator and the oxygen dryer, and then the drying tank that has reached the limit of water absorption is manually replaced to ensure that the two drying tanks can always dry oxygen.

[0038] In the figure, a pressure reducing valve 801 and a pressure sensor 802 are installed on the oxygen storage tank 8, and an airflow monitor 803 is installed on the connecting pipeline between the oxygen storage tank 8 and the ozone generator 9. Specifically, the pressure reducing valve 801, the pressure sensor 802 and the airflow monitor 803 are all existing equipment, for example, the pressure reducing valve 801 is a YQY product, the pressure sensor 802 is a MIK series product, and the airflow monitor 803 is a LC013 product.

[0039] It should be noted that the unit consists of an oxygen booster pump, an oxygen storage tank, a pressure sensor, and a pressure reducing valve. The oxygen dried by the oxygen dryer will be pressurized to 0.6 to 1.0 MPa by the oxygen booster pump and enter the oxygen storage tank for storage. At the same time, a pressure sensor is loaded on the oxygen storage tank. When the gas pressure in the tank is less than 0.6 MPa to 1 MPa, the sensor links the power supply system, and the direct current is turned on by the PLC control power supply system. The electrolyzer system starts the water electrolysis reaction, produces gas, and the oxygen pressure in the tank continues to increase. When the oxygen pressure in the tank is between 0.6 and 1.0 MPa, the pressure sensor detects it, the power supply system is turned off by the PLC, and the electrolyzer system no longer produces the water electrolysis reaction. When the ozone generator system is working, the 0.6 to 1.0 MPa oxygen in the oxygen storage tank is reduced in pressure by the pressure reducing valve to release 0.15 to 0.2 MPa of oxygen into the ozone generator to produce ozone. Specifically, the PLC circuit adopts the existing circuit.

[0040] like Figures 4 to 8As shown, preferably, the ozone generator 9 includes a sealed cabinet 901, a perforated partition 902 and an ozone generating plate 903. In the figure, one or more layers of perforated partitions 902 are horizontally arranged inside the sealed cabinet 901, a plurality of ozone generating plates 903 are equidistantly installed on the perforated partition 902, and an ozone outlet 904 is installed outside the sealed cabinet 901.

[0041] It should be noted that the perforated partition plate 902 is evenly provided with a plurality of waist-shaped holes to facilitate internal air circulation. The installation density of the ozone generating plate 903 can be flexibly adjusted.

[0042] In the figure, the main body of the ozone generating plate 903 is a ceramic substrate, and a plurality of positioning arms 905 are symmetrically arranged on one side of the top of the ozone generating plate 903. The end flange of the positioning arm 905 forms a positioning flange 906, and the positioning flange 906 is provided with connecting holes and connecting screws. The bottom of the ozone generating plate 903 is provided with a connecting surface 907 for fixing the perforated partition plate 902, and the connecting surface 907 is provided with connecting holes and connecting screws. The top of the ozone generating plate 903 is provided with a connecting boss 908 for connecting the positioning flange 906. Specifically, the structure can be flexibly disassembled and assembled, and the number of ozone generating plates 903 can be adjusted conveniently. Adjacent ozone generating plates 903 are limited by the connecting bosses 908 and the positioning flange 906 on the top, and the bottom of the ozone generating plate 903 is fixed by the connecting surface 907.

[0043] In the figure, a discharge layer 909 is provided on one side of the ozone generating plate 903. The discharge layer 909 is a regular hexagonal grid discharge structure, and a discharge pad 910 is welded to the bottom of the discharge layer 909; an induction layer 911 is provided on the other side of the ozone generating plate 903, and an induction pad 912 is welded to the bottom of the induction layer 911. Specifically, the ozone generating plate is made of existing materials, and the regular hexagonal grid discharge structure can fully react with oxygen in the air to generate more ozone.

[0044] In actual operation, the ozone generation system includes an ozone generator, a power supply, and an ozone detector. After 0.15 to 0.2Mpa oxygen enters the ozone generator, the power supply starts and converts oxygen into ozone through a capacitor. The ozone produced by the ozone generator is 0.1 to 0.15Mpa and enters the ozone detector to monitor ozone-related data.
