[0038] The working principle of the present invention is as follows: (1) Before starting work, the treatment tank 501 and the rotating door 502 are sealed through a bolt. Then, the flue gas to be treated is sent into the treatment cylinder 2 through the inlet pipe 1. When the flue gas flows into the inlet pipe 1, it blows the first fan blade 303. Under the action of the spring 302, the first fan blade 303 drives the first rotating shaft 301 to rotate by a certain angle. The greater the flow rate of the flue gas in the inlet pipe 1, the greater the rotation angle of the first rotating shaft 301. The first rotating shaft 301 drives the first connecting shaft 305 to move through the first connecting rod 304. The first connecting shaft 305 drives the first slider 309 to move through the second connecting rod 306. At the same time, the first connecting rod 304 drives the third connecting rod 311 to move, and the third connecting rod 311 drives the second slider 313 to slide, thereby driving the moving parts of the first rheostat and the second rheostat to move, so as to adjust the output pressure of the first water pump 316 and the second water pump 317, and then increase the amount of alkaline solution sprayed. The greater the rotation angle of the first rotating shaft 301, the greater the output pressure of the first water pump 316 and the second water pump 317. The alkaline solution in the second water tank 314 is pressed into the first water tank 307 through the first water pump 316. Then, under the action of the second water pump 317, the alkaline solution in the first water tank 307 is sent into the nozzle 322, and then sprayed into the treatment cylinder 2 through the nozzle 322, so as to achieve that the greater the flue gas rate in the inlet pipe 1, the greater the spraying rate of the alkaline solution.

[0039] (2) The flue gas entering the treatment cylinder 2 through the inlet pipe 1 enters the circulation pipe in the second water tank 314 through the air supply pipe 319, and then is sent back into the treatment cylinder 2 through the return pipe 320. The alkaline solution in the second water tank 314 is heated through the circulation pipe, so as to recover the heat of the flue gas. At the same time, it is avoided that the over-cooled alkaline solution contacts the over-heated treatment cylinder 2 and causes damage to the treatment cylinder 2. The flue gas in the treatment cylinder 2 is neutralized by the sprayed alkaline solution, and the dust in the flue gas is collected in the alkaline solution. Then, the mixture of the solution and the dust enters the installation cylinder 520 through the drain plate 503.

[0040] (3) While the flue gas is sent into the treatment cylinder 2 through the inlet pipe 1, it blows the second fan blade 513 to rotate. The second fan blade 513 drives the rotating disk 515 to rotate through the transmission shaft 514. The rotating disk 515 drives the fourth connecting rod 517 to move through the third connecting shaft 516. The fourth connecting rod 517 drives the lifting plate 518 to reciprocate up and down through the vertical shaft 506. The lifting plate 518 drives the top shaft 519 to lift and lower. The top shaft 519 is inserted into the circular through hole of the leakage hole 521 to complete dredging, so as to avoid the solution in the installation cylinder 520 from being unable to be discharged. After the treatment is completed, the solution in the treatment tank 501 is discharged through the valve 510. Then, the bolt between the treatment tank 501 and the rotating door 502 is opened. Subsequently, under the rotation of the support plate 511, the fixed plate 512 descends, and then the dust on the installation cylinder 520 is scraped off.
