Multiple connecting rods 303 are symmetrically distributed with the center of the installation bottom plate 301 as the center.

[0026] Furthermore, the installation bottom plate 301 is connected to the installation top plate 302 through the connecting rod 303, and both the installation bottom plate 301 and the installation top plate 302 are fixedly connected inside the upper box body 1.

[0027] The inner wall of the upper box body 1 is fixedly communicated with the inner wall of the lower box body 2. The filter bag 3 is located inside multiple connecting rods 303. The two ends of the filter bag 3 are respectively fixedly connected to the surface of the installation bottom plate 301 and the surface of the installation top plate 302. The inner wall of the filter bag 3 is fixedly communicated with the inner wall of the lower box body 2. An adsorption carbon plate 304 is arranged above the installation top plate 302, and the surface of the adsorption carbon plate 304 is slidably connected to the inner wall of the upper box body 1.

[0028] Furthermore, the adsorption carbon plate 304 is slidably connected to the upper box body 1, which is more convenient for replacement.

[0029] A cleaning mounting plate 305 is fixedly connected to the surface of the upper box body 1. A cleaning telescopic rod 306 is fixedly connected to the surface of the cleaning mounting plate 305. The surface of the cleaning telescopic rod 306 is slidably connected to the surface of the upper box body 1. A dust ejecting plate 307 is fixedly connected to the surface of the cleaning telescopic rod 306. The surface of the dust ejecting plate 307 is movably connected to the surface of the filter bag 3.

[0030] Furthermore, the cleaning telescopic rod 306 drives the dust ejecting plate 307 to beat the filter bag 3 back and forth to clean the dust.

[0031] The discharging mechanism further includes an exhaust pipe 401. The two ends of the exhaust pipe 401 are respectively fixedly communicated with a detection box 402 and a first shunt pipe 403. The two ends of the first shunt pipe 403 are respectively fixedly communicated with the inner walls of the two upper box bodies 1. First control valves 404 are fixedly connected to both ends of the first shunt pipe 403.

[0032] Furthermore, the detection box 402 detects the treated waste gas, which is convenient for cleaning or replacing the dust removal mechanism in time.

[0037] Before use, the waste gas enters from one side of the second shunt pipe 405 through the intake pipe 4 below the device, enters the interior of the filter bag 3 in the upper box body 1 from the lower box body 2, and the waste gas continues to rise after being filtered and dust-removed on the surface of the filter bag 3. It passes through the exhaust hole in the installation top plate 302, is adsorbed and filtered by the adsorption carbon plate 304, and then enters the exhaust pipe 401 through the first shunt pipe 403. The detection box 402 on the exhaust pipe 401 detects the flow rate and composition of the waste gas after treatment to determine whether the filter bag 3 and the adsorption carbon plate 304 inside the device need to be cleaned and replaced. When the adsorption carbon plate 304 needs to be replaced, the adsorption carbon plate 304 is directly slid out along the inner wall of the upper box body 1 for replacement. When the filter bag 3 needs to be cleaned, a plurality of cleaning telescopic rods 306 are driven to drive the ash-discharging plate 307 to slap the surface of the filter bag 3 back and forth, so that the dust falls from the inner wall of the filter bag 3 into the dust collection box 407 inside the lower box body 2. When the adsorption carbon plate 304 is replaced, the dust collection box 407 is simultaneously slid out along the inner wall of the lower box body 2 for replacement and cleaning. When the entire filter bag 3 needs to be replaced or overhauled, the first control valve 404 on the surface of the first shunt pipe 403 on the same side and the second control valve 406 on the surface of the second shunt pipe 405 are closed, and the first control valve 404 on the surface of the first shunt pipe 403 on the other side and the second control valve 406 on the surface of the second shunt pipe 405 are opened to load and unload the upper box body 1 and the lower box body 2 as a whole, without affecting the normal operation of the lime kiln.
