At this time, the spring 5 fixedly connected to the inner side of the slide bar 4 loses pressure and recovers its elasticity, so that the outer side of the slide bar 4 is connected with the slot of the smoke inlet body 3, so that when the smoke that has been filtered once enters the desulfurization and denitrification agent installed in the smoke inlet body 3, the burden of the desulfurization and denitrification agent is reduced.

[0028] When it is necessary to speed up the outflow of smoke, the second motor 19 is started to drive the rotating rod 18 fixedly connected to the front end of the second motor 19 to rotate, so that the rear side of the upper end of the rotating rod 18 rotates inside the front end of the connecting plate 17, and drives the connecting plate 17 to move up and down, so that the right end of the main gear 16 rotatingly connected to the inner side of the connecting plate 17 is meshed with the fixed seat 20, so that the main gear 16 slides up and down on the left end of the fixed seat 20, and drives the rack 15 meshed with the left end of the main gear 16 to move up and down, and the smoke outlet of the smoke outlet body 14 tightly fitted on the right side of the rack 15 is intermittently scraped, and at the same time, the outer side of the upper end of the rack 15 is slidably connected to the upper left side of the fixed seat 20, and the rack 15 is limited.
