<p>PROBLEM TO BE SOLVED: To provide a solvent adsorbing method and device which includes an adsorption part where the gas to be treated is permeated through a circulating adsorption mat to adsorb a solvent and a desorption part where a high temp. desorption gas is permeated to separate the solvent from the adsorption mat, and to decrease the amt. of the desorption gas, and to provide a small-sized solvent recovering device. SOLUTION: A preheating part C where preheating air G3 is permeated through an adsorption mat 6 is disposed just prior to a desorption part B so as to preheat the adsorption mat 6. By this method, the amt. of desorption gas G2 supplied to the desorption part B can be decreased. Further, by repeatedly permeating the heating air G3 in the opposite direction to the traveling direction of the adsorption mat 6, heat exchange between the adsorption mat 6 and the heating air G3 is enough performed, and the air g3 used for preheating is enough cooled to become such a state including almost no solvent.</p> |
