HAZARDOUS WASTE INCINERATION FLUE GAS PURIFICATION SYSTEM AND PURIFICATION METHOD

Provided in the present invention are a hazardous waste incineration flue gas purification system and purification method, relating to the technical field of hazardous waste incineration flue gas purification. An efficient quenching and deacidification coupling apparatus for hazardous waste incineration flue gas comprises a reaction tower; a spraying device is arranged at a top end of the reaction tower, and a first liquid-intake pipe and a second liquid-intake pipe are arranged at an inlet end of the spraying device and used to convey cooling substances and deacidification substances; a gas intake pipe and a gas output pipe are provided on the reaction tower; and an output pipeline is provided at a bottom end of the reaction tower and is used to output a substance generated in the reaction tower. After flue gas enters the reaction tower through the gas intake pipe, the cooling substances and deacidification substances in the first liquid-intake pipe and the second liquid-intake pipe are mixed with the flue g
