SEAWATER FLUE GAS DESULFURIZATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an aeration apparatus and a seawater flue gas desulfurization apparatus having the same where oxidation reaction is accelerated and good processing is achieved.

SOLUTION: The seawater flue gas desulfurization apparatus include: a flue gas desulfurization absorption tower 102 which allows exhaust gas 101 and seawater 103 to be in gas-liquid contact to desulfurize SO2into sulfurous acid (H2SO3); a dilution mixing tank 105 which is disposed under the flue gas desulfurization absorption tower 102 and which dilutes and mixes used seawater 103A containing sulfur with diluting seawater 103; and an oxidation tank 106 having the aeration apparatus 120 which is disposed downstream of the diluting-mixing tank 105 to carry out water quality recovery of diluted and used seawater 103B. In the seawater flue gas desulfurization apparatus, microbubble 151 is supplied by a microbubble generator 150 to the seawater 103 which is supplied to the flue gas desulfurization absorption tower 102.
