However, adsorption is an exothermic process, which results in the heat generated at the bottom, which is not well dissipated. 3. The organic waste gas has various kinds, and some organic substances with oxygen-containing and active properties are easy to catch fire under the condition of local high temperature. This has brought the potential safety hazard for equipment operation, enterprise's production.
