Abstract
A product gas generated through the decomposition reaction of organohalogen compounds and steam is neutralized with an alkali solution and is left to stand for a predetermined period of time, while a neutralization product generated in this neutralization reaction is caused to precipitate in the alkali solution and is then removed. In order to remove the neutralization product completely, a takeout tube is disposed to plunge into a waste gas processing tank and a disk-shaped plate is fastened at the distal end of the takeout tube in parallel to the bottom surface of the waste gas processing tank , while the takeout tube opens in the lower surface of the plate at the center thereof. Thus the solid-liquid separation efficiency of the neutralization product and the alkali solution is improved and the quantity of alkali solution remaining in the neutralization product that is disposed of as waste is decreased.
