SEAWATER EXHAUST GAS DESULFURIZATION SYSTEM, AND POWER GENERATOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a seawater exhaust gas desulfurization system for efficiently treating sulfur component absorbing seawater and reducing the size of an oxidation tank, and a power generator system.SOLUTION: A seawater exhaust gas desulfurization system 10 includes an exhaust gas desulfurization absorbing column 11 for bringing exhaust gas 25 into gas-liquid contact with absorbing seawater 21a to wash exhaust gas 25 and an aeration device 41 provided downstream of the exhaust gas desulfurization absorbing column 11 to supply air 29 to sulfur component-containing sulfur component absorbing seawater 14 and has an oxidation tank 12 for performing the water quality restoring treatment of the sulfur component absorbing seawater 14, a seawater supply line L11 for supplying seawater 21 to the exhaust gas desulfurization absorbing column 11, and an air branch line L12 for supplying a part of the air 29 supplied to the oxidation tank 12 to a column bottom part 11a of the exhaust gas desulfurization absorbing column 11.
