Its purpose is to change the mechanical properties, physical properties and chemical properties of metal materials to meet the different requirements of different workpieces or different parts of the same workpiece. Heat treatment of metal materials is an important part of mechanical manufacturing. It can improve the wear resistance, fatigue resistance, corrosion resistance and oxidation resistance of metal materials, thereby improving the quality and life of products.

[0003] Waste gas is generated during the heat treatment of metal materials. These waste gases mainly come from the heat treatment of various metals, non-metals and mineral materials, such as annealing, quenching, tempering, etc. These waste gases contain a large amount of particulate matter, sulfur oxides and nitrogen oxides, as well as volatile organic compounds. These substances not only pollute the atmosphere, but may also cause harm to human health.

[0004] In order to solve the problem of waste gas generated by heat treatment of metal materials, effective treatment measures need to be taken. At present, a variety of effective waste gas treatment technologies have been developed, including dry treatment and wet treatment. Among them, dry treatment includes activated carbon adsorption, combustion and other methods, while wet treatment includes absorption, adsorption and other methods. These treatment methods can effectively remove harmful substances in waste gas and protect the environment and human health.

[0005] However, the position of the suction hood for absorbing exhaust gas in the common heat treatment waste gas treatment device is fixed, which makes it inconvenient to adjust the height and angle of the suction hood. In view of this, the present application proposes a heat treatment waste gas treatment device. Utility Model Content
