Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas recovery, in particular to an organic waste gas activated carbon fiber adsorption recovery device. Background Art

[0002] Organic waste gas is the general name for volatile organic compounds, abbreviated as VOCs in English. It refers to organic solids or liquids that are easily volatilized at normal temperature and pressure and exist in the form of gas. Volatile organic compounds (VOCs) in organic waste gas are one of the important precursors to the formation of atmospheric pollutants. They themselves are also highly toxic. In order to avoid affecting the environment, it is usually necessary to recycle and treat the organic matter in the waste gas.

[0003] Most of the current organic waste gas recovery devices have a relatively simple internal structure. The activated carbon fibers used to adsorb organic waste gas are usually directly arranged and installed inside the device. Due to the fluidity of the gas, the waste gas stays in the activated carbon fibers for a short time, making it difficult for some organic matter to be fully absorbed, thereby reducing the recovery efficiency.
