Background
With the development of society and the stricter national environmental protection policy, the treatment of various organic waste gases is currently the key point of environmental treatment work in China. At present, the treatment of a large amount of low-concentration organic waste gas is carried out by adopting an activated carbon adsorption process and a device. The process has good effect and low investment, but the activated carbon can reach saturation after running for a certain time, thereby losing effectiveness. At the moment, all the activated carbon of the device is replaced, and new activated carbon is reloaded to restore the adsorption effect; or the spent activated carbon is regenerated. However, the investment of the matched activated carbon regeneration device and the waste gas adsorption treatment system is high, so that the matched activated carbon regeneration device is not abundant at present, and the replaced activated carbon is generally sent back to an activated carbon production plant for uniform regeneration by the plant and then sent back to a use unit. The operation is time-consuming and labor-consuming, the cost is high, and the universal popularization is not facilitated.
Based on the above-mentioned dilemma, the present invention is learned through research: generally, in a production enterprise or an industrial park where organic waste gas is generated, there are organic waste gas generation points distributed at multiple points, which are generally also distributed for treatment, and treatment devices are respectively built.

A set of small activated carbon regeneration device can be established in an enterprise or a park, activated carbon saturated by the activated carbon adsorption device in the whole enterprise or the park is respectively taken to the device for regeneration, and the activated carbon is recycled after regeneration. In order to reduce the investment cost, the existing high-concentration organic waste gas treatment device (various combustion decomposition devices) in an enterprise or a park can be used as a desorption gas treatment and purification device of a regeneration system. The present invention has been designed and studied based on the above-mentioned idea.
