The harmful substances in the baking process of the baking paint room are mainly benzene based compounds, non methane total hydrocarbons and other organic compounds. Their chemical composition is complex, and the raw materials, composition and concentration of the products are different. There are various treatment methods with different characteristics. Heating the waste to 170-300 degrees and burning it in a catalytic bed to achieve purification is suitable for the treatment of organic waste with high temperature, high humidity, and high concentration. The exhaust gas from the paint baking room is usually at room temperature. To catalyze the waste, it needs to be heated to 170-300 degrees, which consumes a lot of heat energy. After catalysis, the exhaust gas from the flow distributor is directly discharged, which invisibly wastes a lot of heat energy.

The heat recovery core utilizes the catalytic exhaust gas to exchange heat with harmful gases flowing out of the paint baking room. It increases the inlet temperature of the electric heater while reducing the exhaust temperature, achieving energy conservation and emission reduction.
