Claim:
A wet flue-gas desulfurization equipment having an absorbing tower, the absorbing tower comprising: an absorption unit configured to use an absorbent slurry to absorb and remove soot/dust, sulfur oxides, and substances attributable to boiler fuel components that are contained in an exhaust gas emitted from a combustion apparatus; a tank unit configured to temporarily store the absorbent slurry flowing down from the absorption unit, wherein a diameter of the tank unit is larger than a diameter of the absorption unit, and the tank unit and the absorption unit are joined together by a conical member, the conical member comprising a conical shell; and an entrance flue having an opening at a front end and configured to allow passage of the exhaust gas, the front end of the entrance flue being defined by at least opposing vertically extending sidewalls, the entrance flue penetrating an outer surface of the conical member and the vertically extending sidewalls of the front end of the entrance flue extending to a region in which the absorbent slurry falls from the absorption unit.
