Description

technical field

[0001] The invention belongs to the field of organic waste gas treatment, and in particular relates to a regeneration control system and a regeneration control method for a large-capacity organic waste gas adsorption device. Background technique

[0002] The emission of organic waste gas has the characteristics of complex composition, low concentration and large emission volume, especially the organic waste gas emitted during the coating process is mostly more than 100,000 cubic meters per hour, and the total VOCs concentration is about 100ppm. Adsorption is a cost-effective treatment method for low-concentration organic waste gas. Due to the limited adsorption capacity of a single adsorption device, it is necessary to replace the adsorbent or regenerate the adsorbent after the adsorption is saturated to maintain the treatment effect continuously. However, regular replacement of the adsorbent has problems such as heavy operating workload and high operating co...
