VOC organic waste gases are categorized into: injection molding waste gases, spraying waste gases, acid mist waste gases, generator waste gases, and kitchen oil fume 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 a significant impact on human health, potentially causing damage to the brain and nervous system upon reaching a certain level. Therefore, the key to treating VOC organic waste gases lies in the initial stage of processing. The treatment process includes: adsorption stage, desorption stage, intermittent watering stage, cooling and drying stage, separation stage, and measurement recovery stage. Different pretreatment processes are usually added based on varying waste gas conditions.
