[0002] Waste gas treatment, also known as waste gas purification or waste gas management, primarily refers to the management of industrial waste gases generated in industrial sites. These waste gases may include dust particles, smoke and soot, odorous gases, and toxic and hazardous gases. The purpose of waste gas treatment is to pre-treat waste gases before they are discharged to meet emission standards. Adsorption is a commonly used waste gas treatment method that utilizes the adsorption properties of adsorbents to transfer odorous substances from the gas phase to the solid phase. This method is suitable for treating a variety of waste gases, including organic waste gases.

[0003] However, existing waste gas treatment systems often need to be shut down for cleaning and desorption after adsorbing the waste gas. The cleaning time is long and the work efficiency is low. In addition, the recyclable part of the waste gas after desorption will be wasted, which wastes this part of resources and increases operating costs. Utility Model Content
