The working principle is as follows:

the process gas is horizontally added from the gas inlet 701, changes direction downwards through the elbow connection pipe 702, passes through the upper transition taper pipe 703, reduces the flow section, and accelerates the gas flow speed to enter the mixer 704. The washing water tangentially enters the mixing chamber 704 through the second washing water conveying pipe 14, and water flow rotates at a high speed in the mixing chamber under the action of pressure and violently collides with high-speed air flow from the air inlet 701 to realize first mixing of air and water. Under the dual action of the driving of the pressure of the air inlet 701 and the gravity, the air-water mixture makes downward spiral motion, reaches a tangential inlet 6 of a 2 nd washing water conveying pipe, collides with water flow entering in a reverse tangential direction to generate second air-water mixture, and then spirally moves downward to reach an air-water outlet pipe 706 to be discharged into a space around the mixer. The space in the cylinder 8 downward from the elbow joint 702 is filled with the gas-water mixture, the gas in the gas-water mixture upwards floats, the water downwards sinks, and a large amount of upwards-floating bubbles are generated; the gas in some bubbles is broken before forming new bubbles, the gas is contacted with water, solid particles are absorbed by the water, the gas in the bubbles is not contacted with the water if the gas in some bubbles, particularly some larger bubbles, is not broken, and fine solid particles in the bubbles are wrapped in the bubbles, so that the smaller the bubbles, the better, and the contact interface between gas and water is maximized. Therefore, the air-water outlet pipe 706 is formed in a zigzag shape, thereby achieving the effect of breaking bubbles. In addition, a bubble breaker 4 is arranged above the air-water outlet pipe 706, and bubbles which are not broken before are cut again. When the gas floats out of the liquid level from the gas-water mixed liquid, most solid particles, particularly larger particles, in the process gas are washed away, but a small amount of solid particles are not washed away; thus, a plurality of stages 9 are provided to further purify the rising process gas. Purified water is added from the water inlet 13, flows through the first layer of tower plate, overflows the overflow weir, falls into the second layer of tower plate, and then flows through the third layer of tower plate, the fourth layer of tower plate, the fifth layer of tower plate and the sixth layer of tower plate in the same way; the rising process gas passes through the dense small holes of the tower plate 9 and contacts with the purified water flowing through the tower plate, a large amount of floating bubbles are generated on the tower plate at the moment, and the gas is fully contacted with the water to transfer the solid particles in the water into the water again; the process gas is purified by the multi-layer tower plate 9 and flows away from the process gas outlet when reaching the top. The water containing the solid particles slowly sinks and is drawn off from the sewage drain 15. Larger particles sink to the bottom of the conical shell quickly and are discharged from the slag discharge port 17 periodically, and the rest is black water which is discharged from the second sewage discharge port 16.
