Description

Industrial waste gas treatment equipment system

technical field

The utility model relates to the technical field of waste gas treatment equipment, in particular to an industrial waste gas treatment equipment system.

Background technique

Exhaust gas refers to the toxic and harmful gases emitted by human beings in the process of production and life. Especially chemical plants, steel plants, pharmaceutical plants, as well as coking plants and oil refineries, etc., the exhaust gas emitted has a strong odor, which seriously pollutes the environment and affects human health. The atmosphere is a mixture of certain proportions of nitrogen, oxygen, carbon dioxide, water vapor and solid impurity particles. As far as dry and clean air is concerned, calculated by volume, under standard conditions, nitrogen accounts for 78.08%, oxygen accounts for 20.94%, argon accounts for 0.93%, carbon dioxide accounts for 0.03%, and the volume of other gases is negligible. With the development of modern industry and transportation, more and more substances are continuously emitted into the atmosphere, and the types are more and more complex, causing drastic changes in the composition of the atmosphere. When substances other than the normal composition of the atmosphere are harmful to human health, the growth of animals and plants, and the weather and climate, we say that the atmosphere is polluted. In industrial or chemical production, a large amount of dusty exhaust gas is generated, and the exhaust gas has a strong odor. The exhaust gas contains a certain amount of oil fume and harmful substances. The direct emission causes great pollution to the environment and seriously affects human health. However, the functions of the existing waste gas treatment device are relatively single, so the treatment of waste gas is not sufficient and thorough, and the discharge into the atmosphere will still pollute the environment and endanger human health. Therefore, a mature and efficient industrial waste gas treatment equipment is urgently needed.
