<P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment apparatus which suppresses the deterioration of a denitration catalyst and has a long life. <P>SOLUTION: The exhaust gas treatment apparatus is provided with a first bag filter 15 which removes dusts in exhaust gas, an activated carbon supply means 23 which is arranged on the back stream side of the first bag filter 15 and mixes activated carbon to the dust-removed exhaust gas and a second bag filter 17 which is arranged on the back stream side of the activated carbon supply means 23, carries the denitration catalyst and allows the activated carbon supplied by the activated carbon supply means 23 to be stuck to the surface thereof. The exhaust gas is cleaned by the first bag filter 15 metals in the dusts is removed, by passing through the first bag filter 15, a treating temperature of the second bag filter 17 is lowered up to the temperature which does not cause firing of the activated carbon, by allowing the dust-removed exhaust gas to pass through the second bag filter 17, heavy metals and dioxins in the exhaust gas are removed with the activated carbon stuck to the surface thereof and denitration is performed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
