Exhaust gas refers to the valueless gas that has been squeezed out of the industry for its release or survival. A wide range of exhaust gases is classified as follows: Exhaust gas treatment
1. Press the emission subcategory of the source of the exhaust gas:
The waste generated by the human industry production campaign is called industrial exhaust (including fuel combustion exhaust gas and production process exhaust gas); the exhaust gas from human survival movement is called living exhaust gas; the exhaust gas from human transportation movement is called traffic exhaust gas, including automobile exhaust gas (car Exhaust), high-altitude aircraft exhaust, train and ship exhaust, etc.; waste generated by human agricultural activities is called agricultural exhaust.
2. According to the classification of pollutants contained in the exhaust gas
According to the physical form of the contained pollutants, it can be divided into: exhaust gas containing particulate matter, including gaseous pollutants, etc. It can also be divided into: fume-containing exhaust gas, industrial dust-containing exhaust gas, coal dust-containing exhaust gas, sulfur-containing compound exhaust gas, nitrogen-containing compound exhaust gas, carbon-containing oxide exhaust gas, halogen-containing compound exhaust gas, and hydrocarbon-containing compound exhaust gas.
3. According to the formation of waste gas classification
(1) The pollutants that are directly discharged by a pollutant from a pollution source are called primary pollutants, and their physical and chemical properties have not yet changed;
(2) Secondary pollutants are secondary pollutants that produce chemical interactions between primary pollutants in the atmosphere or with the normal components of the atmosphere. It is often more severe than the pollution of a single pollutant on the situation and the human body.
