Abstract: Through a practical example of treatment of the flue gas from the remelting process of aluminum alloy tailings, the design an d calculation method of exhaust hood, as well as the principles and the equipment s of dust removal, smoke abatement and harmful gas elimination were studied. Com bination of centrifugal and wet dust removal can purify the dust high efficiently. The carbon black and harmful gases in the flue gas can be removed by adding a small quantity of activator to the absorption solution. The application results are that the dedusting efficiency is 97.43%, Cl2 control efficiency is 88.03%, the exhaustfume blackness is lower than Ringelman number I, and the purification device resistance is 126Pa.
