Abstract
A method for treating waste gases contaminated with toxic or odorous compounds in the form of a mist using a regenerative incinerator system is provided. The contaminated waste gas is passed through a first regenerator so that the waste gas is heated by contact with the packing material contained therein. This hot contaminated waste gas is passed through a combustion chamber to oxidize the compounds in the waste gas. The hot treated waste gas is passed through another regenerator to cool the gas and heat the packing material contained therein. The cleaned gas is discharged. Part of the cleaned gas is heated and passed through the regenerator to volatilize and/or remove compounds remaining in the regenerator after passage of the waste gas, thereby cleaning the regenerator.
