[0028] The water distribution pipe 202 is used to transport the condensed solution, and the water distribution pipe 202 is provided with two groups and staggered. At the same time, the water distribution pipe 202 is connected with a nozzle 203, and the nozzle 203 is suitable for spraying the condensed solution;

[0029] A flow blocking mechanism 3 is installed on the tower body 1, and the flow blocking mechanism 3 is used to fully contact the tail gas with the condensed solution. The flow blocking mechanism 3 includes a sealing plate 301 installed on the tower body 1, and an opening groove 106 with a size matching that of the sealing plate 301 is opened on the tower body 1;

[0030] A connecting plate 302 is fixedly mounted on the sealing plate 301, and a fastener 303 is connected to the connecting plate 302. The fastener 303 is suitable for penetrating the connecting plate 302 and connecting with the tower body 1;

[0031] In the present application, a sealing gasket is provided at the contact position between the sealing plate 301 and the tower body 1 to prevent the condensed solution from flowing out from the gap between the sealing plate 301 and the tower body 1;

[0032] At the same time, four groups of baffles 304 are fixedly installed on one side of the sealing plate 301 close to the tower body 1. The baffles 304 have through holes, and the four groups of baffles 304 are all arranged tilted downward, and the four groups of baffles 304 are staggered in the vertical direction, and separate the interior of the tower body 1 into an S-shaped channel;

[0033] The baffle plate 304 has a sliding rod 305, and a sliding slot 107 adapted to the sliding rod 305 is provided on the inner wall of the tower body 1. The baffle plate 304 is adapted to be engaged in the sliding slot 107 through the sliding rod 305, so as to provide auxiliary support for the baffle plate 304.

[0040] In summary: through the coordinated use of the cylinder 401, the support rod 402, the cross bar 403, the mounting cover 404, the scraper 405, the sealing plate 301, the fastener 303 and the screen 104, the dirt attached to the inner wall of the tower body 1 can be scraped, and the screen 104 can collect the fallen dirt.
