EXHAUST GAS TREATMENT FOR ELECTRIC FURNACE

摘要

PROBLEM TO BE SOLVED: To efficiently remove harmful substance such as dioxines contained in the exhaust gas from an electric furnace and to prevent the scattering. SOLUTION: In an exhaust gas treatment device for the electric furnace consisting of a direct sucking system exhaust path A for directly sucking the exhaust gas from the electric furnace 1 and a building system exhaust path B for indirectly sucking the exhaust gas from a ceiling hood 4 of a building of the electric furnace, fine powdery activated carbon is blown into the direct sucking system exhaust path A to be mixed with the exhaust gas in a mixing tower 9 and then the exhaust gas is introduced into the building system exhaust path B to mix the activated carbon with the exhaust gas in the building system exhaust path, and then the activated carbon is collected with a bag house 13 provided on the building system exhaust path B.
