<p>PROBLEM TO BE SOLVED: To provide a method for recycling an unreacted neutralizer in a collected mixture by a dust collector effectively, decomposing fly ash-containing DXN and the like in the collected mixture by a dust collector more effectively than conventional and treating an exhaust gas with simple equipment. SOLUTION: In the treatment method for defusing a collected mixture by a dust collector which is obtained by collecting a neutralized product, an unreacted neutralizer and fly ash by a dust collector 7, which are produced when the neutralizer is introduced into an exhaust gas generated from a refuse incinerator 1 and a deleterious gas in the exhaust gas is neutralized, the method is characterized by circulating a part of the exhaust gas at the discharge port of the dust collector 7 to a treatment system prior to an inlet of the exhaust gas of the dust collector 7 via an exhaust gas circulation duct 19 and introducing a treating agent to neutralize and adsorb the deleterious gas in the exhaust gas onto the exhaust gas circulation duct 19.</p> |
