摘要： [PROBLEMS] To suppress an increase in the discharge amount of harmful substances and operating cost in a cement kiln. [MEANS FOR SOLVING PROBLEMS] This combustion exhaust gas G processing device comprises a dust collector (6) collecting dust in combustion exhaust gas G, a wet dust collector (7) collecting water soluble components and dust in the combustion exhaust gas G passed through the dust collector (6), and a catalyst tower (12) decomposing and removing NOx and/or dioxins in the combustion exhaust gas G passed through the wet dust collector (7). The device also comprises a reheater (11) heating the combustion exhaust gas G discharged from the wet dust collector (7) at the front stage of the catalyst tower (12) and an oxidizer adding device (10) adding an oxidizer to the combustion exhaust gas G passed through the dust collector (6). The device desirably comprises a solid/liquid separator (16) separating slurry discharged from the wet dust collector (7) into solid and liquid phases, a mercury adsorbing tower (17) adsorbing mercury in liquid separated in the solid/liquid separator (16), and a heat recovering device (13) heating the combustion exhaust gas G discharged from the catalyst tower (12) at the rear stage of the catalyst tower (12).
