The industrial kiln refers to heating equipment used in industrial production and is widely applied to industries such as metallurgy, chemical industry, building materials, machinery and the like. The waste gas treatment of the industrial kiln is to reduce pollution, meet the environmental protection requirement, realize resource recycling and ensure safe production. The existing industrial kiln has a plurality of defects. First, an industrial kiln without an exhaust gas treatment structure directly emits a large amount of exhaust gas, which contains various pollutants such as particulate matters, sulfur oxides, nitrogen oxides, etc. These exhaust gases are produced on the one hand by insufficient combustion of the fuel and by reactions of the materials at high temperatures, and on the other hand by the air flow in the kiln and by volatilization of the materials. For the defects, the conventional treatment method mainly optimizes the combustion process, improves the fuel combustion efficiency, reduces the generation of incomplete combustion products, enhances the sealing performance of the kiln, and reduces the air mixing and the volatilization of materials. However, these methods have certain drawbacks. Optimizing the combustion process often requires more advanced combustion equipment and precise control techniques, is costly and requires high technical demands on the operator. Strengthening the kiln tightness may affect the ventilation effect in the kiln, leading to insufficient combustion or excessive local temperature, affecting the product quality and the service life of the kiln.
