OXIDATION TANK, SEAWATER EXHAUST GAS DESULFURIZATION SYSTEM, AND POWER GENERATOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an oxidation tank, a seawater exhaust gas desulfurization system, and power generator system capable of efficiently performing the treatment of sulfur component absorbing seawater and reducing the total air amount supplied into the oxidation tank.SOLUTION: An oxidation tank 12 includes a diluting seawater supply line L14 connected to a tank body and supplying diluting seawater 13b to a sulfur component-containing sulfur component absorbing seawater 14 discharged from an exhaust gas desulfurization absorbing column 11, an aeration device 31 provided in the tank body and supplying air 33 to the sulfur component absorbing seawater 14 discharged from the exhaust gas desulfurization absorbing column 11, and a dissolved oxygen concentration measuring apparatus 32 for measuring the concentration of dissolved oxygen in the sulfur component absorbing seawater 14. On the basis of the relation of the preliminarily calculated length of the oxidation tank 12 and the concentration of the dissolved oxygen in the sulfur component absorbing seawater 14, the air amount supplied to the sulfur component absorbing seawater 14 from the aeration device 31 is adjusted.
