Technical Field
[0001] The utility model relates to the technical field of processing equipment, in particular to VOC combustion processing equipment. Background Art
[0002] VOC stands for volatile organic compounds. In the ordinary sense, VOC refers to volatile organic compounds; however, in the environmental sense, it refers to a class of active volatile organic compounds, that is, the type of volatile organic compounds that can cause harm. There are many ways to treat VOC. Since VOC organic compounds are flammable, they can be treated at room temperature or by catalytic oxidation combustion. This method is relatively complete and can basically convert VOC into CO2 and H2O.
[0003] However, most of the existing VOC combustion treatment equipment adopts the method of introducing combustion into a boiler or an incinerator. The boiler or the incinerator directly mixes the VOC exhaust gas with the combustion aid in the internal space. Since the VOC exhaust gas and the combustion aid are not mixed evenly in the cavity, the boiler or the incinerator is not in sufficient contact with the combustion aid during the combustion process, which may easily lead to insufficient combustion treatment of some VOCs, harmful residues in the exhaust gas, resulting in exhaust gas emissions not meeting the standards and poor treatment effect. Based on this, the utility model designs a VOC combustion treatment equipment to solve the above problems. Utility Model Content
