SEAWATER FLUE GAS DESULFURIZATION SYSTEM AND POWER GENERATION SYSTEM

摘要

This seawater flue gas desulfurization system (10) is characterized by comprising: a flue gas desulfurization absorption tower (11) for cleaning exhaust gas (25) by bringing the exhaust gas (25) and absorbed seawater (21a) into gas liquid contact with each other; an oxidation tank (12) which is provided on the downstream side of the flue gas desulfurization absorption tower (11) and provided with an aeration device (41) for supplying air (29) to sulfur content absorbed seawater (14) containing sulfur content and performs water quality restoration treatment on the sulfur content absorbed seawater (14); a seawater supply line (L11) for supplying seawater (21) to the flue gas desulfurization absorption tower (11); and an air branching line (L12) for supplying part of the air (29) to be supplied to the oxidation tank (12) to a tower bottom part (11a) of the flue gas desulfurization absorption tower (11).
