Abstract
An object is to provide an exhaust-gas treatment apparatus capable of realizing a dissolved-salt spray method easily and at low cost. An exhaust-gas treatment apparatus that removes SOand SOcontained in combustion exhaust gas includes a desulfurization apparatus based on the lime-gypsum method. Desulfurizing effluent, containing dissolved salt, from the desulfurization apparatus is sprayed to an upstream side of the desulfurization apparatus to remove SO. A wet electrical dust precipitator may be provided downstream of the desulfurization apparatus. Furthermore, effluent from the wet electrical dust precipitator may be made to merge with the desulfurizing effluent from the desulfurization apparatus.
