Abstract

PURPOSE: To obtain stable and high desulfurization efficiency, by providing a supply control system of absorber so that the volume of absorbent in the absorption solution circulating at constant flow rate may be more than the reaction equivalent of the sulfur oxides in the exhaust gas introduced into the absorption tower, in a wet type exhaust gas desulfurization apparatus.
CONSTITUTION: In a wet type exhaust gas desulfurization apparatus consisting of cooling tower to cool the exhaust gas, absorption tower 3 to absorb and remove sulfur oxides from the exhaust gas cooled by the cooling tower 1, and absorption tower circulation tank 4 which circulates the absorption liquid such as lime slurry into the absorption tower, a control system is provided which adjusts the opening degree of an absorbent flow rate control valve 35 so that the supply flow rate of required absorbent slurry may be obtained from the sulfur oxide total volume signal 33 and concentration signal 34 from absorbent slurry flow meter 36 by means of a controller 37, by determining the sulfur oxide total valume by a calculator 32 from the exhaust gas flow rate signal and sulfur oxide concentration signal of the exhaust gas. Thus, a stable and high desulfurization efficiency may be obtained.
