The function of this design is to enable the lower part of the gas-liquid mixing chamber 19 to form a gas-liquid mixing chamber 19 by controlling the rotation speed or the liquid inlet amount in the later stage. Figure 2The cavity area 30 shown in the dotted line portion is formed to facilitate the gas to be purified to be sprayed smoothly into the gas-liquid mixing chamber 19 . A rotating shaft 15 is provided at the lower part of the centrifugal rotating disk 20; the rotating shaft 15 is rotatably arranged on the middle part of the partition 6 of the device body through a rolling bearing 17; a liquid inlet chamber 11 is provided in the rotating shaft 15, and the liquid inlet chamber 11 is communicated with the bottom of the gas-liquid mixing chamber 19, and then a plurality of support blocks 10 are provided in the liquid inlet chamber 11; a power drive assembly is provided on the rotating shaft 15; a rotary joint 12 is provided at the lower part of the rotating shaft 15; the liquid inlet 13 of the rotary joint 12 is connected to the liquid inlet pipe 34; the bottom of the rotating disk upper shell is connected to the bottom of the rotating disk bottom shell, and the connection constitutes a connecting platform 20-1; the connecting platform 20-1 also serves to improve the rigidity of the connection between the rotating disk upper shell and the rotating disk bottom shell; an air inlet chamber 29-1 is provided in the connecting platform 20-1. In this embodiment, in order to improve the uniformity of gas entering the gas-liquid mixing chamber 19, as Figure 2 As shown, the outer wall of the connecting platform 20-1 is provided with a circle of grooves 29, and the inner side of the grooves 29 is provided with a circle of the air inlet chamber 29-1; the air inlet chamber 29-1 is connected to the main air inlet hole 26 through a plurality of air delivery channels 28; the main air inlet hole 26 is connected to the rotary joint 22. The rotary joint 22 can be an existing rotary joint, which can provide gas transportation under the relative rotation of the pipeline, and the air inlet chamber 29-1 is connected to the gas-liquid mixing chamber 19; the air inlet of the rotary joint 22 is connected to the air inlet pipe 24, and when in use, the gas to be purified is transported by the air inlet pipe 24 after passing through the air pump.

The mixed gas-liquid mixture continues to be swung toward the periphery under the action of centrifugation.

Then, the rotation speed of the driving motor 8 or the opening of the regulating valve 35 is controlled by the control circuit, so that the amount of liquid discharged from the top of the gas-liquid mixing chamber 19 is caused to be the same as the amount of liquid flowing in from its bottom, so as to dynamically maintain the cavity area 30 and realize continuous gas-liquid mixing.

[0028] A purification method, using a purification system as described above, comprises the following steps:
