FIELD: removal and processing of solid wastes.
SUBSTANCE: invention relates to the field of thermal processing of solid municipal wastes (SMW) at waste incineration plants (WIP), namely to the part of flue gas cleaning from melting of ash-slag wastes formed during SMW combustion. System for cleaning flue gases from melting ash and slag wastes of a waste incineration plant includes series-arranged electric furnace for melting ash-slag wastes of a waste incineration plant at a temperature of complete decomposition in the formed flue gases of dioxins and carcinogenic substances, water-cooled gas duct, made as a pipe in a pipe, through the annular space of which cooling liquid is pumped, a water-cooled gas cooler, through which flue gases pass, wherein the system includes water nozzles for cooling the gas cooler, installed on top and on the side of the gas cooler, wherein the number and exact location of the nozzles are determined depending on the capacity of the electric furnace and the temperature of the flue gases, water-cooled medium-temperature gas duct, made as a pipe in a pipe, through the annular space of which cooling liquid is pumped, a bag filter, a carbon filter, an exhaust fan.
EFFECT: design of a system for cleaning exhaust flue gases from melting ash and slag wastes of a waste incineration plant, which is characterized by simplicity and compactness.
