Activated carbon adsorption desorption condensation recovery device is an organic waste gas treatment device that combines adsorption and condensation methods. Activated carbon adsorption desorption condensation recovery device gives full play to the advantages of both methods, has high purification efficiency, transforms the disadvantages of adsorption and condensation methods, regenerates the adsorbent, uses low-temperature water vapor for desorption, restores the activity of the adsorbent, and recycles the desorbed organic matter to achieve the purpose of purifying waste gas.
