Description

Technical Field

[0001] This utility model specifically relates to the field of activated carbon adsorption equipment technology, and more specifically to a highly efficient activated carbon adsorption equipment with cyclic desorption capability. Background Technology

[0002] Against the backdrop of an increasingly severe environmental protection situation, industrial waste gas treatment has become a critical issue that urgently needs to be addressed. Volatile organic compounds (VOCs), as a significant component of air pollutants, have a wide range of sources, covering numerous industries such as chemicals, coating, printing, and electronics. The VOCs emitted by these industries have complex and diverse concentrations and compositions, posing a serious threat to the ecological environment and human health.

[0003] Activated carbon adsorption technology is widely used in VOCs treatment due to its high efficiency and economy. Activated carbon has a rich microporous structure and a large specific surface area, which can effectively adsorb pollutants in waste gas and achieve purification. However, in traditional activated carbon adsorption equipment, the adsorption performance will significantly decrease when the activated carbon becomes saturated. Directly replacing the activated carbon is not only costly, but the discarded activated carbon may also become a new source of pollution. Traditional activated carbon regeneration methods, such as thermal regeneration, are energy-intensive, require sophisticated equipment, and are prone to damaging the activated carbon structure. Conventional chemical regeneration is prone to generating secondary pollution. Therefore, realizing the regeneration and recycling of activated carbon is the key to improving the efficiency of adsorption equipment, reducing operating costs, and reducing environmental pollution.

By installing the desorption device and the cleaning device with the adsorption tower body, the activated carbon adsorption device can achieve cyclic desorption while reducing secondary pollution after desorption, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:
