Abstract
A wet type flue gas desulfurization apparatus desulfurizes flue gas existing inside an absorption tower by causing the flue gas to come into gas-liquid contact with an absorbent, and the absorbent is fed through a header pipe and sprayed through nozzles. In the apparatus, the absorbent accumulated inside the absorption tower is fed to the nozzles to circulate in the absorption tower. The apparatus includes: a bypass pipe feeding the absorbent through the nozzles from a downstream of the nozzles into the absorption tower; a tank arranged at an intermediate location on the bypass pipe; a perforated plate arranged inside the tank; and an access port opening on a side surface of the tank above the perforated plate to communicate between an inside and an outside of the tank. The absorbent that freely falls and passes through the perforated plate while scales or impurities are collected above the perforated plate.
