Description

technical field [0001] The invention relates to the field of exhaust gas catalytic treatment devices, in particular to a catalytic combustion device suitable for organic waste gas treatment and an exhaust gas treatment process. Background technique [0002] The catalytic combustion method is also called flameless combustion. Its essence is a catalytic oxidation reaction. Using a suitable catalyst and utilizing the deep catalytic oxidation activity of the catalyst, the organic component is combined with oxygen at a temperature below the ignition point (200-400°C) to form a non-toxic Toxic CO 2 and H 2 O, to achieve the purpose of purification. The catalytic combustion method is especially suitable for the purification of organic waste gas with high concentration of organic matter, complex components and no recovery value. [0003] For low-concentration organic waste gas, the existing catalytic combustion devices not only have low treatment efficiency for waste gas, but als...
