Further, the smoke dust adsorption device is one of an activated carbon adsorption device or an electrostatic adsorption device. After the bag-type dust collector adsorbs large particles, the active carbon adsorption device or the electrostatic adsorption device is adopted to adsorb the small particles, so that the smoke dust can be removed by 99.9 percent.

Further, the incinerator is lined with a heat insulation protective layer. The gas in the incinerator is usually as high as 400-500 ℃, and the arrangement of the heat insulation protective layer is favorable for prolonging the service life of the incinerator.
