Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to VOCs waste gas treatment equipment. Background Art

[0002] VOC is the abbreviation of volatile organic compounds. In the common sense, VOC refers to volatile organic compounds. According to the definition of the World Health Organization, compounds with a boiling point of 50℃-250℃ under normal conditions are volatile organic compounds; however, the definition in the environmental sense refers to a class of active volatile organic compounds, that is, the type of volatile organic compounds that can cause harm.

[0003] The filter element is an important device in the exhaust gas treatment device. The stacking of filter elements with different functions plays the role of absorbing different types of exhaust gases. There are two technical difficulties in the replacement of traditional filter elements. First, the exhaust gas treatment needs to be suspended when the filter element is replaced. Second, a shell is set on the outside of the traditional filter element, and adjacent filter elements are connected by bolts. This takes a long time to replace the filter element. Overall, the replacement efficiency of traditional filter elements is low. Utility Model Content
