[0002] In the purification equipment of industrial volatile organic pollutants, adsorption beds are often used to adsorb industrial volatile organic pollutants. Activated carbon is generally used as the adsorbent in the adsorption bed. The main structure of the adsorption bed includes the air inlet flared part, activated carbon The bed body and the air outlet constriction, the opposite sides of the activated carbon bed body are respectively connected to the air inlet flaring part and the air outlet constriction part, and the air distribution plate is fixed on the air inlet flaring part, and multi-layer activated carbon is arranged in the activated carbon bed body. The partition is used to place activated carbon. After the industrial volatile organic pollutants in the adsorption bed are saturated, desorption and regeneration will be carried out, that is, the industrial volatile organic pollutants adsorbed on the activated carbon will be desorbed by hot air, so that the activated carbon can be recycled. , the adsorption bed needs a higher temperature during the desorption process. Generally, an electric heating device is installed in front of the air inlet of the adsorption bed to make the hot air entering the adsorption bed reach a temperature suitable for desorption, but each desorption requires electricity. Heating equipment consumes a lot of energy and has high operating costs. In the process of adsorption plus catalytic combustion, if the heat energy of catalytic combustion is not used, it will also cause waste and cause thermal pollution to the environment.
