VOC organic waste gases are categorized into: injection molding waste gases, spray painting waste gases, acid mist waste gases, generator waste gases, and kitchen oil smoke waste gases. The primary source of VOC organic waste gases is the VOC content in various coatings and decorative materials. VOC organic waste gases are pollutants that harm the environment. VOC stands for volatile organic compounds, and these waste gases have significant impacts on human health, potentially causing damage to the brain and nervous system. Therefore, the key to treating VOC organic waste gases lies in handling them at the initial stage. The treatment process includes: adsorption stage, desorption stage, intermittent watering stage, cooling and drying stage, stratification separation stage, and metering recovery stage. Different pretreatment processes are typically added based on the specific conditions of the waste gases.
