[0041] The working principle and use process of the utility model are as follows:

[0042] First, the operator starts the second motor 24 and injects high-temperature water vapor into the inside of the oxygen removal box 1 through the high-temperature vapor pipe 13, and then injects oxygen-containing water into the distribution box 16 through the water inlet pipe 15, at this time, the oxygen-containing water in the distribution box 16 is sprayed onto the flow divider 14 through the spray opening 17, at this time, the flow divider 14 can refine the sprayed water droplets to increase the surface area of the oxygen-containing water droplets as much as possible, the refined oxygen-containing water droplets are scattered on the filler 3, at this time, the oxygen-containing water droplets contact the high-temperature water vapor and start to heat up, when the temperature reaches the saturation temperature of water, the carbon dioxide and oxygen in the oxygen-containing water droplets are released in the form of gas, thereby reducing the oxygen content in the oxygen-containing water droplets, and finally the water droplets after oxygen removal fall into the water tank 27 through the filler 3 and the oxygen removal box 1.

[0043] And a part of water beads will be heated to the gasification temperature and start to move upward with oxygen, carbon dioxide in the form of water vapor, and eventually these gas-liquid mixed steam will contact the gas-liquid separator 20, at this time the operation of the second motor 24 will make the drive shaft 25 and the driving gear 26 rotate, and because the driving gear 26 and the driven gear 22 are meshed with each other, therefore the driven gear 22 and the gas-liquid separator 20 as a whole will start to rotate under the meshing of the driving gear 26, and the rotating gas-liquid separator 20 will more fully contact the gas-liquid mixed steam, in this process, water vapor will contact the gas-liquid separator 20 and re-condense into water beads and then fall down, and oxygen, carbon dioxide will directly pass through the gas-liquid separator 20 and the top cover 23 to be discharged outside the oxygen removal tank 1 as a whole.

[0044] When the operator needs to replace the filler 3, the operator first stops the injection of high-temperature steam and oxygen-containing water and removes the closure plate 11 and the bolt 12, and then the operator starts the first motor 6, and with the operation of the first motor 6, the rotating shaft 7 and the first connecting rod 8 will start to rotate, and the rotation of the first connecting rod 8 will drive the second connecting rod 9, so that the second connecting rod 9 also starts to rotate, at the same time, the other end of the second connecting rod 9 will drive the connecting plate 5 in the rotating process, so that the connecting plate 5, the cross rod 4 and the placing tank 2 as a whole start to move to the right, and finally the placing tank 2 and the filler 3 will be completely moved to the right side of the oxygen removal tank 1, at this time the operator can directly replace the filler 3 in the placing tank 2.
