Why do factories emit toxic gases?

It is necessary to burn fossil fuels because factories have to start machines when they are working. Combustible substances of fossil fuels will produce carbon monoxide and carbon dioxide when burned. Carbon monoxide is toxic, which can lead to tissue suffocation and even death in severe cases. Carbon dioxide released by combustion (one of the main sources of greenhouse gases) is one of the factors that accelerate global warming.

In addition to combustible substances, fossil fuels also contain many impurities, such as sulfur dioxide, carbon disulfide and other sulfide particles, which are released into the air with the combustion of fossil fuels, making the discharged places have pungent odor, which will increase the incidence of respiratory diseases and make the condition of patients with chronic diseases deteriorate rapidly.

Extended data:

Exhaust emission refers to the pollutants in the exhaust gas discharged from the chimney or exhaust pipe hole of the factory. It is a serious pollution source of atmospheric environment. All kinds of waste gases emitted by industrial enterprises in the process of combustion and production. Organic volatile substances in coatings are the main cause of air pollution, and the pollution in the coating process is much more serious than that in the coating factory.

In the production of coatings, the amount of solvent put into the atmosphere does not exceed 2% of the solvent used in the production of coatings, and the solvent volatilizes less than 0.25% in the process of ball milling production. However, in the coating process, the loss varies from 20% to 80% with different types of coatings and coating methods.

For example, in the air spraying operation, 50% ~ 70% of solvent-based coatings are dispersed in the paint mist during the painting process, and all organic solvents are volatilized and released into the atmosphere. The harmful waste gas emitted in painting is mainly concentrated in the painting production line, and the spray booth, drying room and drying room are the main sources of waste gas.
