Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas catalytic combustion device. Background Art

[0002] Catalytic combustion is a typical gas-solid phase catalytic reaction. It reduces the activation energy of the reaction with the help of a catalyst. The oxidation of organic matter occurs on the surface of the solid catalyst, producing CO2 and H2O at the same time, and releasing a large amount of heat. Because of its low oxidation reaction temperature, it greatly inhibits the formation of high-temperature NOx from N2 in the air. Moreover, due to the selective catalytic effect of the catalyst, it is possible to limit the oxidation process of nitrogen-containing compounds (RNH) in the fuel, so that most of them form molecular nitrogen (N2); the previous exhaust gas catalytic combustion devices mostly adopt a sealed structure, and the entire exhaust gas catalytic combustion treatment process is invisible. After long-term use, the inner wall of the device is stained with a lot of combustion residual impurities, which are difficult for users to clean in time, not only affecting the normal use of the subsequent device, but also corroding the inner wall of the device and affecting the service life of the device; and in the process of exhaust gas catalytic combustion, a lot of heat will be generated. The heat is directly discharged by the fan, which is easy to cause the outdoor air temperature to be too high, and the energy loss is more obvious. For this reason, we propose an exhaust gas catalytic combustion device. Utility Model Content
