VOC organic waste gases are categorized into: injection molding waste gases, spray painting waste gases, acid mist waste gases, generator waste gases, and kitchen油烟 waste gases. The primary source of VOC organic waste gases is the VOC content in various paints and decorative materials. VOC organic waste gases are pollutants that harm the environment. VOC stands for volatile organic compounds, and these gases have a significant impact on human health, potentially causing damage to the brain and nervous system at high levels. Therefore, the key to VOC organic waste gas treatment is to address it at the initial stage. The treatment process includes: adsorption stage, desorption stage, intermittent watering stage, cooling and drying stage, separation stage, and measurement and recovery stage. Different pretreatment processes are often added based on the specific conditions of the waste gases.
