VOC organic waste gases are categorized into: injection molding waste gases, spraying 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 coatings and decorative materials. VOC organic waste gases are pollutants that harm the environment, with VOCs being volatile organic compounds. These waste gases have a significant impact on human health and can cause damage to the brain and nervous system upon reaching a certain level. Therefore, the key to treating VOC organic waste gases is to handle them at the initial stage. The treatment process includes: adsorption phase, desorption phase, intermittent water washing phase, cooling and drying phase, stratification separation phase, and measurement and recovery phase. Depending on different waste gas conditions, additional pre-treatment processes are typically added.
