Description

technical field [0001] The invention relates to an exhaust gas catalytic device, in particular to a steam waste heat circulation type exhaust gas catalytic device. Background technique [0002] The catalytic combustion process is carried out in a catalytic combustion device; the organic waste gas is first preheated to 200-400 °C through a heat exchanger, and then enters the combustion chamber. When passing through the catalyst bed, the molecules of hydrocarbons and the oxygen molecules in the mixed gas are separated Activated by adsorption on the surface of the catalyst. Since surface adsorption reduces the activation energy of the reaction, hydrocarbons and oxygen molecules are rapidly oxidized at lower temperatures to produce carbon dioxide and water. Generally, it is applied on the carrier, so its shape also varies according to the carrier. Carriers include spheres, cylinders and various special-shaped bodies made of γ-Al2O3, porous ceramic honeycomb bodies covered with...
