Chemical waste gas often contains a wide variety of pollutants with complex physical and chemical properties and varying toxicity, seriously polluting the environment and affecting human health. The composition of chemical waste gas varies greatly among different chemical production industries. According to the form in which the pollutants exist, chemical waste gas can be divided into particulate pollutants and gaseous pollutants. Particulate pollutants include dust particles, particulate matter, smoke, fog, coal dust, etc., while gaseous pollutants include sulfur-containing compounds, chlorine-containing compounds, carbon oxides, hydrocarbons, halogen oxides, etc.
