WET EXHAUST GAS PURIFICATION DEVICE

WIPO Patent Application WO/2012/153705

A1

　Provided is a wet exhaust gas purification device that enables the simple cleaning/removal of PM accumulated in a demister, enables the use of a low porosity, high collection efficiency demister, and exhibits high exhaust gas purification efficiency. After converting PM that is accumulated inside a demister (50, 51) and that contains an oil component into a low viscosity liquid using heated wash water, the wet exhaust gas purification device sprays the heated wash water so that the wash time and volume of wash water volume required for cleansing/removal are negligible. After cleansing/removal, the demister (50, 51) can be re-used in a state that is almost as good as new. Thus, the pressure drop between the gas stream upstream side and the gas stream downstream side of the demister (50, 51) is increased, the power of a suction blower (7) is increased by the increase in the pressure drop, and the problem of insufficient exhaust suction by the suction blower (7) is avoided.
