[0002] Volatile organic compounds usually refer to organic compounds with a saturated vapor pressure greater than 133 Pa at 25°C. Their main components are hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons, sulfur hydrocarbons, nitrogen hydrocarbons, aromatic hydrocarbons and polycyclic aromatic hydrocarbons. Volatile organic waste gas usually has complex components, large changes in emission concentration, is not easily soluble in water, contains acids or alkalis, and is difficult to treat.

[0003] The treatment steps of volatile organic waste gas include filtration, adsorption and incineration. When filtering, multi-layer filter plates are often required to perform multi-stage filtration of organic waste gas. However, multi-layer filter plates are prone to clogging after long-term use, and the surface of the filter plates is not convenient to clean. When adsorbing, activated carbon is often used to adsorb compounds in organic waste gas. The adsorption capacity of activated carbon will decrease after adsorbing too many compounds. The existing device is not convenient to replace activated carbon for adsorption. The waste gas after adsorption may still contain harmful compounds. The existing device is not convenient for detecting the waste gas after adsorption, and it is not convenient to perform secondary adsorption. For this reason, a volatile organic waste gas catalytic combustion device is proposed. Utility Model Content
