PROCESSING METHOD AND APPARATUS FOR REFUSE INCINERATOR WASTE GAS

摘要

PROBLEM TO BE SOLVED: To effectually utilize heat recovered by a temperature lowering processing, improve efficiency of a dust collector and protect the same, and further prevent dioxin in waste gas from being again synthesized by rapidly lowering temperature of the waste gas and performing a scavenging processing for the same. SOLUTION: In a waste gas processing apparatus which includes a waste heat boiler 2 disposed downstream a refuse incinerator 1 for recovering heat from waste gas, and a dust collector 4 for removing dust from waste gas disposed downstream the waste heat boiler 2, there is disposed a rotary regenerating heat exchanger 14 between the waste heat boiler 2 and the dust removal apparatus 4 for heat exchange between the waste gas and air.
