VOC organic waste gases are categorized into: injection molding waste gas, spray painting waste gas, acid mist waste gas, generator waste gas, and kitchen油烟 waste gas. The primary source of VOC organic waste gases is the VOC content in various paint and decorative materials. VOC organic waste gases are pollutants that significantly impact the environment, with VOCs being volatile organic compounds. These waste gases have a profound effect on human health, leading to brain and nervous system damage at high levels. 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 spray phase, cooling and drying phase, stratification separation phase, and metered recovery phase; different pre-treatment processes are usually added based on varying waste gas conditions.
