PURPOSE:To enhance the recovery rate of an org. solvent by sending the exhaust in a condenser from the primary absorption and desorption device side to a secondary org. solvent adsorption and desorption device connected to the condenser to intermittently adsorb the solvent and returning the uncondensed component to the primary adsorption device to adsorb the solvent. CONSTITUTION:A gas S contg. the org. solvent is continuously adsorbed by the primary org. solvent adsorption and desorption device 12 provided with plural adsorption chambers 14 and 15, the adsorption chambers 14 and 15 are alternately desorbed, and the waste desorbed gas is treated by a condenser 11 connected to the primary device 12. The exhaust in the condenser 11 is supplied to the secondary org. solvent adsorption and desorption device 29 and intermittently adsorbed. The desorbed gas is introduced into the secondary device 29 in the course of the adsorption, and the waste desorbed gas is supplied to the condenser 11 and treated. The exhaust in the condenser 11 from the secondary device 29 side is joined to the treated gas inlet part of the primary device 12.
