Wet flue gas desulfurization system

摘要

This invention provides a wet flue gas desulfurization system for removing sulfur dioxide present in flue gas by absorption into an absorbent slurry, which comprises an absorption tower (1) having at the bottom thereof a tank (2) for holding an absorbent slurry; a circulating pump (4) for feeding the absorbent slurry within the tank to a flue gas inlet section (la) in the upper part of the absorption tower and bringing the absorbent slurry into contact with flue gas; and a slurry preparation compartment (22) provided on one side of the tank of the absorption tower and separated from the flue gas passage section (26) by a partition wall (21) having its lower end submerged below the surface of the absorbent slurry, whereby an absorbent and water constituting the absorbent slurry are directly introduced into the slurry preparation compartment. Thus, the absorbent supply system is improved to achieve a marked simplification of the equipment.
