In today's era of social and economic development, the development of industry has brought progress to mankind, but also has many negative effects on society. Air pollution is one of the important ones. It is not only one of the most prominent environmental problems in the world but also in our country. It not only causes huge losses to the national economy, but also brings serious harm to people's lives. The large amount of pollutants contained in industrial waste is an important cause of air pollution in China. The country strongly supports the treatment of industrial waste gas, and waste gas treatment equipment manufacturers have taken a major step towards sustainable development.
　　Exhaust gas refers to the unused gas emitted in the process of industrial baking or life. There are many types of exhaust gas, which are classified as follows.
　　1. Particulate pollutants: Particulate substances that pollute the atmosphere are also called aerosols. In environmental science, aerosol is defined as a solid or liquid substance suspended in the atmosphere, or particulate matter or particulate matter. According to the nature of their source, aerosol can be divided into primary aerosol and secondary aerosol. The former refers to the particulates emitted from the emission source, such as the smoke particles discharged from the smoke box, the dust blown by the wind, and the waves sprayed by the sea; the latter refers to the emission from the source as a gas, formed by some atmospheric chemical processes The particles, such as H2S and S02 gas from the emission source, are finally converted into sulfate particles through the atmospheric oxidation process. The soot mainly comes from thermal power plants, steel plants, metal smelters, chemical plants, cement plants, and industrial and civil boilers.
　　2. Radioactive pollution: Since the 1940s, air pollution caused by radioactive dust has attracted increasing attention. This is mainly caused by nuclear weapons tests and nuclear power plant accidents. People need to breathe air to sustain life. According to statistics from exhaust gas treatment equipment manufacturers, an adult breathes about 20,000 times a day and inhales 15 to 20 cubic meters of air. Therefore, the polluted air has a direct impact on human health. The hazards of atmospheric pollutants to the human body are various, mainly manifested as respiratory diseases and physiological dysfunctions, as well as the irritation of eyes and nose and other mucosal tissues. Advocate everyone to protect the environment, starting from industrial factories, it is imperative to control industrial exhaust pollution.
