VOC organic waste gases are categorized into: injection molding waste gases, spraying 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 paints and decorative materials. VOC organic waste gases are a type of environmental pollution gas. VOC stands for volatile organic compounds, and these gases have a significant impact on human health, causing damage to the brain and nervous system at certain levels. Therefore, the key to treating VOC organic waste gases lies in the initial stage of their treatment. Treatment processes include: adsorption stage, desorption stage, intermittent watering stage, cooling and drying stage, separation stage, and measurement and recovery stage. Different pretreatment processes are typically added based on the specific conditions of the waste gases.
