The working principle is as follows: after the motor 12 is started, the output shaft of the motor 12 drives the driving rod 13 to rotate, the fan blades 14 rotate under the action of the driving rod 13, air flow is formed by the fan blades 14 in the upper cavity 6, negative pressure is formed at a position close to the air inlet 4, tail gas entering from the air inlet 4 flows downwards along with the air flow, the tail gas is accumulated at the collecting groove 15 and is led into the air guide pipe 8 from the air guide port 9 at an accelerated speed, the tail gas enters into the upper cavity 6 from the air inlet 4 and is led into the air guide pipe 8 from the air guide port 9 under the flow guide of the flow guide equipment, the tail gas in the air guide pipe 8 is sprayed into water from the spray head 11 through the air guide pipe 10 at the lower end, the air guide pipe 8 rotates under the action of the driving equipment, the tail gas in the air guide pipe 8 is diffused to the periphery of the water, the air guide pipe 8 rotates under the driving of the driving rod 13, the first crushing blades 16 on the air guide pipe 8 rotate along with the rotation of the air guide pipe 8, and crush tail gas bubbles sprayed from the spray head 11, so that tail gas in bubbles can not be contacted with water due to the isolation of the bubbles, the second crushing blade 18 rotates along with the air duct 8, and the second crushing blade 18 is blown by gas under the action of bottom tail gas bubbles, so that the first spring 19 moves up and down in a reciprocating manner, after chlorine in the air duct 8 reacts with water at the tail end of the air duct 8, water enters the air duct 8 from the tail end of the air duct 8, tail gas quickly enters the air duct 8, so that the whole air duct 8 is filled with chlorine, water possibly flows back to the upper chamber 6, so that the tail gas can not enter water in the lower chamber 7, after the air pump 24 is started, the air pump 24 blows outside cold air into the lower chamber 7 of the water treatment tank 5, so that the water temperature in the lower chamber 7 is reduced, the temperature in the water is guided out under the action of the heat conducting plate 27, and heat on the heat conducting plate 27 is quickly diffused by the heat radiating fins 28 on the heat conducting plate 27, the concentration of the solution is higher and higher along with the gradual entering of tail gas in water, the buoyancy force borne by the floating ball 31 is larger and larger along with the increase of the concentration of the solution, the height of the floating ball 31 in the solution is gradually increased, when the floating ball 31 and the conductive block 29 are contacted with each other, a circuit is connected, current passes through the alarm 32, the alarm 32 gives an alarm, redundant tail gas in the lower cavity 7 after water treatment rises to the upper part of the water surface, the tail gas in the transition box 5 flows back into the upper cavity 6 along with the airflow to be treated by the negative pressure formed in the upper cavity 6, the impeller 36 rotates under the airflow formed by the exhaust pipe 33 and the air return pipe 34, the rotating shaft 35 rotates under the driving of the impeller 36, the worm wheel 37 on the rotating shaft 35 rotates along with the rotation of the rotating shaft 35, the worm 38 and the worm wheel 37 are meshed with each other, the worm wheel 37 rotates along with the rotation of the worm wheel, the reciprocating lead screw 39 rotates under the driving of the worm 38, the lead screw nut 41 sleeved on the reciprocating lead screw 39 reciprocates, the lead screw nut 41 is fixedly installed in the annular scraper 40, the limiting rod on the upper end of the annular scraper 40 and the transition box 5 is acted on the inner wall of the transition box to limit slide groove 40, so that the reciprocating scraper moves up and the transition box 5 up-down, thereby enabling the reciprocating scraper to move up and down.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
