Introduction to the Painting Industry

Coating refers to the application of protective or decorative layers on metal and non-metal surfaces, and is the most basic technical means used for surface protection and decoration of products. The painting process can be simply summarized as: pre-treatment → spraying → drying or curing. Pre treatment generally includes oil removal, rust removal, and passivation (phosphating) processes. The selection of oil removal, rust removal, phosphating and other treatment methods for different coatings and corrosion resistance requirements depends on the condition of the workpiece raw materials. In the pre-treatment rust removal process, sandblasting, shot blasting or grinding processes are also selected according to the needs of different industries and departments.

Characteristics of Painting Waste Gas Industry

According to the painting production process, painting exhaust gas mainly comes from pre-treatment, spraying, and drying processes. The pollutants emitted are mainly dust or acid mist generated during pre-treatment, paint mist and organic solvents generated during painting, and organic solvents generated during drying and volatilization. Paint mist mainly comes from the scattering of solvent based coatings during air spraying operations, and its composition is consistent with the coating used. Organic solvents mainly come from solvents and diluents during the use of coatings, with the vast majority being volatile emissions. Their main pollutants are xylene, benzene, toluene, etc. The harmful exhaust gases emitted during painting are mainly concentrated on the painting production line, among which the painting room, drying room, and drying room are the main sources of exhaust gases.

Paintingwaste gas treatmentworkmanship

1. For the painting industry, there are two main processes that generate exhaust gas: spraying and drying.

2. According to the characteristics of exhaust gas generated in the painting industry, for painting exhaust gas with high air volume, low concentration, complex composition and no recycling value, thermal oxidation method is preferred, and the heat is reused in the drying process.

Product advantages:

1. High adsorption efficiency and strong ability;
2. The equipment has a compact structure, small footprint, simple and convenient maintenance and management, and low operating costs;
3. Capable of simultaneously processing multiple mixed organic waste gases;
4. Adopting an automated control operation design, the operation is simple and safe;
