Description

Technical Field

[0001] This application relates to the technical field of waste purification equipment, and in particular to environmental protection equipment for waste gas purification. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially from chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries. The waste gas emitted by these plants has a strong odor and seriously pollutes the environment and affects human health. In order to prevent the direct emission of waste gas from harming the environment and human body, purification and environmental protection devices are often used to filter and purify the waste gas in order to improve the environmental friendliness of production and daily life.

[0003] When the relevant purification and environmental protection equipment is used, the waste gas generated during production and life is usually discharged into a sealed container. Then, the filtration device in the container, such as graphite or activated carbon, absorbs and filters the toxic and harmful substances in the waste gas. After the waste gas has been filtered by graphite or activated carbon and the toxic and harmful substances have been absorbed, it can be discharged from the sealed container, thereby achieving the filtration and purification treatment of the waste gas.

[0004] However, when using the above methods, because the waste gas is often filtered out from the graphite or activated carbon at normal temperature and pressure inside the container when it is introduced into the container to filter and absorb toxic and harmful substances, the filtration process is time-consuming, inefficient, and ineffective. Therefore, those skilled in the art have provided waste gas purification and environmental protection equipment to solve the problems mentioned in the background art. Utility Model Content
