METHOD FOR TREATING EXHAUST GAS CONTAINING PFC AND/OR HFC AT LOW WORKING TEMPERATURE AND APPARATUS THEREFOR

摘要

PURPOSE: To provide a method and an apparatus for treating exhaust gas containing PFC and/or HFC by treating the exhaust gas at low working temperature, thereby reducing energy consumption and danger of fire. CONSTITUTION: The apparatus comprises a heating device(1) for heating incoming waste gas containing PFC and/or HFC and water at 50 and 300 deg.C; an ozone generator(2) for generating ozone; a mixing device(4) for receiving and uniformly mixing the ozone from the ozone generator and the waste gas containing PFC and/or HFC and the water from the heating device to form a gas mixture; and a reactor(3) for receiving the gas mixture from the mixing device, wherein the reactor contains an iron oxidation catalyst and the gas mixture and the iron oxidation catalyst are subjected to gas/solid contact and oxidation reaction at 50 to 300 deg.C.
