[0002] Oxygen is a colorless and odorless gas, which is the most common elemental form of oxygen. Its melting point is -218.4°C, boiling point is -183°C, it is not easily soluble in water, about 30 mL of oxygen is dissolved in 1 L of water, oxygen accounts for about 21% in the air, and liquid oxygen is sky-blue. Solid oxygen is a blue crystal.

[0003] For example, an industrial oxygen preparation device for removing moisture and dust with the patent application number CN202222071246.0 includes a first box body, an oxygen-enriched membrane is installed on the inner wall of the first box body, a first fan is installed at the bottom of the inner wall of the first box body, and the output end of the first fan is fixedly connected with a first pipeline. In this industrial oxygen preparation device for removing moisture and dust, the water pump in the dust removal mechanism is connected to an external power supply. The water pump can inject the water inside the second box body into the inner wall of the pipe body and spray it out through multiple atomizing nozzles to form multiple water mists. Then, when air is injected into the air inlet, the air is purified through multiple water mists to carry out dust removal work. The water mist after contacting the air will be re-introduced into the water on the inner wall of the second box body for recycling. It can also drain and inject water through two valve bodies. Without using a filter screen to filter dust, it can also carry out dust removal work on the air. There is no need to disassemble, only water discharge and injection are required, which is time-saving and labor-saving and relatively convenient.

[0004] Although the above-mentioned industrial oxygen preparation device for removing moisture and dust is time-saving and labor-saving and relatively convenient, the oxygen purification efficiency and the oxygen purification effect are not high. Content of the Utility Model

[0008] Preferably: A sealing ring II is fixedly arranged at the connection between the air delivery pipe and the fixing plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

Specific implementation mode

[0016] Specific embodiment 1: Please refer to Figures 1-3 A purification device for oxygen preparation, including a purification tank 10; the upper end of the purification tank 10 is clamped with an upper cover 11; the upper end of the upper cover 11 is fixedly provided with a water injection port 16; the inner side of the water injection port 16 is threadedly connected with a screw plug 15; the outer circumference of the upper end of the purification tank 10 is fixedly provided with a water storage tank 17; a water pump 14 is arranged between the water storage tank 17 and the purification tank 10; the input end of the water pump 14 is communicated with the purification tank 10; the output end of the water pump 14 is communicated with the water storage tank 17; an air transmission pipe 13 is fixedly arranged on one side of the purification tank 10; the air transmission pipe 13 is communicated with the inner side of the upper cover 11; an air outlet pipe 12 is fixedly arranged on the lower side of the purification tank 10; the air outlet pipe 12 communicates the inside and outside of the lower end of the purification tank 10; six high-pressure spray heads 18 are equidistantly arranged inside the purification tank 10 corresponding to the lower end of the water storage tank 17; the purification tank 10 is communicated with the water storage tank 17 and each high-pressure spray head 18 respectively; a first filter plate 19 is arranged at the upper end of the air transmission pipe 13; the first filter plate 19 abuts against the inner upper end of the purification tank 10; a fixing plate 24 is fixedly arranged at the lower end of the connection between the water pump 14 and the purification tank 10; it further includes an oxygen pipeline 28 fixedly arranged on the fixing plate 24; the lower end of the oxygen pipeline 28 is threadedly connected with a cover 27; the upper end of the cover 27 abuts against an oxygen-enriched membrane 26; the upper side of the oxygen-enriched membrane 26 abuts against a porous sponge 25; a second filter plate 20 is fixedly arranged inside the purification tank 10 between the fixing plate 24 and the first filter plate 19; the second filter plate 20 is slidably connected with six buoys 21; the diameter of the outer circumference of the lower end of each buoy 21 is greater than the aperture of the lower end surface of the second filter plate 20; the highest point of the movement track of each buoy 21 presses against the lower end surface of the first filter plate 19; by arranging a porous sponge 25 and an oxygen-enriched membrane 26 inside the oxygen pipeline 28, the water flow and air first pass through the porous sponge 25 and then through the oxygen-enriched membrane 26, ensuring the purification effect of oxygen; by arranging the porous sponge 25 to occupy a certain space inside the oxygen pipeline 28, the water flow directly contacting the oxygen-enriched membrane 26 is reduced, and at the same time, the dust and impurities in the water flow close to the oxygen-enriched membrane 26 are blocked, improving the efficiency of oxygen purification.

[0017] Please refer to Figure 2 where a first sealing ring 22 is fixedly arranged at the connection between the gas delivery pipe 13 and the second filter plate 20; a second sealing ring 23 is fixedly arranged at the connection between the gas delivery pipe 13 and the fixing plate 24; by arranging the buoy 21 to be slidably connected to the second filter plate 20, when the high-pressure spray head 18 sprays water, the buoy 21 is located at the lower side between the fixing plate 24 and the second filter plate 20. As the water gradually enters the space between the fixing plate 24 and the second filter plate 20, the buoy 21 blocks the pores of the second filter plate 20, so that when the water pump 14 pumps water again, there is sufficient water on the upper side of the fixing plate 24, and the air on the upper side of the fixing plate 24 must pass through the water flow before entering the porous sponge 25, improving the air purification efficiency.

[0018] During operation, the gas to be treated is largely input into the inner side of the upper cover 11 through equipment such as an air pump arranged outside the gas delivery pipe 13. The water pump 14 is started, and the dust in the air is blocked by the first filter plate 19. Subsequently, the high-pressure spray head 18 sprays water flow to impact the first filter plate 19, washing away the dust on the first filter plate 19, and at the same time dissolving the oxygen in the air into the water flow. Then the water flow flows downward, pressing down the buoy 21. The gap between the buoy 21 and the second filter plate 20 forms a channel for the gas and water flow to flow. After the water flow moves to the porous sponge 25, the water flow and part of the air pass through the porous sponge 25 and then reach the oxygen-enriched membrane 26. Through the oxygen-enriched membrane 26, the water and oxygen are separated, and the oxygen is discharged from the air outlet pipe 12;

[0019] When a certain amount of water flow sprayed by the high-pressure spray head 18 flows out, the buoy 21 rises, blocking the gaps of the second filter plate 20. The air between the second filter plate 20 and the fixing plate 24 fully passes through the water flow on the fixing plate 24 and is purified. Subsequently, the air gradually diffuses out from the oxygen-enriched membrane 26. Since the porous sponge 25 occupies a certain volume, excessive water will not accumulate in the oxygen pipeline 28, thus not affecting the purification of oxygen; the water pump 14 is started, and the water pump 14 pumps the sufficient water flow on the upper side of the fixing plate 24 into the water storage tank 17. The water flow sprays out from the high-pressure spray head 18, scouring the dust in the air and the dust on the first filter plate 19. The buoy 21 descends, and the water flow flows down again from the pores between the buoy 21 and the second filter plate 20 to complete the cycle.
