Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a multi-stage adsorption purification device for treating organic waste gas. Background Art

[0002] With the acceleration of industrialization, the problem of organic waste gas emissions has become increasingly prominent, posing a serious threat to the environment and human health. Traditional organic waste gas treatment methods, such as combustion and condensation, have achieved certain results, but they have problems such as high energy consumption, low treatment efficiency, and possible secondary pollution.

[0003] At present, in order to achieve better treatment effects and to avoid problems such as secondary pollution, corresponding multi-stage adsorption purification devices are usually used to implement multi-stage adsorption treatment operations for waste gas. There are many types of multi-stage adsorption treatment operations on the market, and most multi-stage adsorption treatment operations directly use multi-layer filters to achieve waste gas purification operations. However, direct use of multi-layer filters for filtration has the disadvantage that some odors or other chemical waste gases in the waste gas are difficult to remove. It is not possible to perform liquid water washing purification operations on the waste gas under the premise of multi-stage adsorption treatment, which is not conducive to removing odors and chemical waste gases, affecting the use effect and bringing inconvenience to users. In view of this, we propose a multi-stage adsorption purification device for organic waste gas treatment. Utility Model Content
