TREATMENT OF WASTE GAS AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a waste gas treating method and device capable of treating waste gas at a temperature higher than a prescribed temp, earlier capable of keeping stable irradiation strength without polluting a light source and also capable of improving decomposition efficiency. SOLUTION: The organic chlorine compound in waste gas 3 is absorbed to a photocatalyst 5 by introducing the waste gas 3 into photocatalytic reactor 1 housing the photocatalyst 5 and agitating the photocatalyst 5 by the waste gas 3 and the organic chlorine compound adsorbed to the photocatalyst 5 is decomposed and removed by irradiating the photocatalyst 5 in the photocatalyst reactor 1 with the light from a light source at the outside of the photocatalyst reactor 1 through an optical fiber by the oxidizing function of the photocatalyst 5 manifested by the irradiation.
