EQUIPMENT FOR TREATMENT OF INCINERATION WASTE GAS FOR OBTAINING CLEAN INCINERATION FLY ASH

摘要

PROBLEM TO BE SOLVED: To provide an equipment for treatment of incineration waste gas of an inexpensive cost of equipment without employing the conventional pyrolytic or chemical treatment, and without need of constructing the inside of the high temperature dust-collector in a so-called heat-resistance specification, in which contents of chlorine and sulfur in fly ash can be reduced, and clean incineration fly ash can be obtained when fly ash produced by combustion of domestic and industrial wastes is to be reused to cement or concrete materials. SOLUTION: The equipment for incineration waste gas treatment is provided with an incinerator 1 or an incineration boiler, a first heat exchanger 2 for heat recovery, a high temperature dust collector 3 comprising a multi-cyclone dust collector, a second heat exchanger 4 for heat recovery, and a low temperature dust-collector 5 comprising a bag filter. Contents of chlorine and sulfur in fly ash discharged from the high temperature dust collector 3 can be reduced by setting the temperature in the dust collector 3 at 400-500 deg.C.
