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 a type of environmental pollution, with VOCs being volatile organic compounds. These gases have a significant impact on human health, and at a certain level, they can cause damage to the brain and nervous system. Therefore, the key to treating VOC organic waste gases is to handle 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 usually added based on the specific conditions of the waste gases.
