WASTE GAS TREATING METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a treating method and device which can crack and remove hazardous materials, such as dioxins, in waste gases. SOLUTION: The waste gases generated from an incineration equipment of a small scale or middle scale are scrubbed with water or aqueous solution and the water or aqueous solution after the scrubbing is electrolyzed. The aqueous solution is preferably the aqueous solution containing hydroxides of periodic table group I or II metals alone or in combination of a plurality thereof. The hydroxides preferably consist essentially of potassium hydroxide. Further, a process step of removing solid components from the waste gases prior to scrubbing the waste gases with water or the aqueous solution is preferably disposed.
