PROBLEM TO BE SOLVED: To provide an organic solvent recovery system capable of reducing the amount of drainage recovered by cooling condensation and suppressing the deterioration of quality of organic solvent in a system for adsorbing and removing organic solvent-containing gas with a first adsorbent, on the other hand, desorbing the adsorbed organic solvent with heated air, thereby, adsorbing and removing obtained organic solvent-containing concentrated gas with a second adsorbent, desorbing the adsorbed organic solvent with carrier gas, thereafter, cooling and condensing the organic solvent and liquefying and recovering the organic solvent. ! SOLUTION: An organic solvent recovery system is characterized in that, in the system constituted with an adsorption concentration device which adsorbs and removes organic solvent from organic solvent-containing gas with a first adsorbent, discharges clean gas and, on the other hand, desorbs the adsorbed organic solvent with heated gas and discharges the organic solv |
