FLUE GAS DESULFURIZING APPARATUS

摘要

Provided is a flue gas desulfurizing apparatus adopting the sea water method, for preventing or suppressing such an entrainment of a boiler exhaust gas as is caused when the used sea water flows into the water surface of the diluting sea water, thereby to prevent the leakage of the burned exhaust gas. The flue gas desulfurizing apparatus (1A) uses the sea water method, by which the desulfurization is made by the gas-liquid contact between the sea water to flow from the upper portion of a desulfurizing tower (2) and the sea water to rise from below the desulfurizing tower (2).In the exhaust gas desulfurizing apparatus (1A), the sea water used after desulfurization thereof falls from the desulfurizing tower (2) into the diluting sea water flowing in a water passage (9) and is diluted by its mixing with the diluting sea water, and an impact force relaxing device (20) for relaxing the impact force at the time when the used sea water falls into the diluting sea water is provided below the burned exhaust gas inflow position of the desulfurizing tower (2).
