Abstract

This invention belongs to the technical field of waste gas treatment and discloses a solid waste pyrolysis gasification tail gas treatment device, which solves the technical problems of low purification efficiency and poor purification effect of existing pyrolysis gasification tail gas treatment equipment. The device includes a secondary combustion chamber; a quench tower connected to the secondary combustion chamber; a deacidification unit connected to the quench tower; an activated carbon adsorption component connected to the deacidification unit for adsorbing gaseous dioxins and heavy metals in the tail gas; an electrostatic precipitator connected to the activated carbon adsorption component for adsorbing particulate matter in the tail gas; and a denitrification unit connected to the electrostatic precipitator. Therefore, through the cooperation of the electrostatic precipitator and the activated carbon adsorption component, the excellent charge performance of activated carbon powder makes it easier to capture under the action of an electric field. The charged activated carbon powder has a stronger adsorption capacity for gaseous pollutants, thereby enhancing the purification effect and improving the purification efficiency.
