Background
At present, the purification treatment of VOCs mostly adopts an activated carbon adsorption device, and the working principle of the activated carbon adsorption device is as follows: adsorption process because of the unbalanced and unsaturated molecular attraction or chemical health on the activated carbon surface (solid surface), when the activated carbon surface is in contact with a gas, the gas molecules are attracted, concentrated and retained on the activated carbon surface, which is adsorption. The desorption of activated carbon is the reverse of adsorption, and is an operation process in which the adsorbed substance is separated from the saturated adsorbent to regenerate the adsorbent. The adsorbed substance on the surface of the activated carbon decreases with the increase of the temperature, and the temperature of the adsorbent is increased, so that the adsorbed component can be desorbed, and the method is also called temperature-variable desorption.
