<p>PURPOSE:To economically and effectively remove ash and acidic gaseous substance contained in exhaust gas. CONSTITUTION:In providing an electric dust-collecting part negatively charging ash particles in exhaust gas by the corona discharge between a discharge electrode and a dust collecting electrode in a casing treating exhaust gas, at least a part of the dust collecting electrode 6 is constituted of reticulated elements 11, 12 and a water flow film Wa is formed on the surface of the dust collecting electrode 6 by a treatment soln W containing water and an alkali agent emitted from above and negatively charged ash particles are collected by the water flow film Wa and the acidic gaseous substance in the exhaust gas is absorbed into the water flow film Wa.</p> |
