Zusammenfassung:To provide a solvent recovery system capable of more precisely diluting a recovered solvent than before.SOLUTION: A solvent recovery system comprising a feed channel for feeding gas including a solvent to a cooler, the cooler for cooling the gas including a solvent fed from the feed channel to liquefy the solvent, a recovery unit for recovering the liquefied solvent, and water adding means of adding water to dilute the solvent recovered by the recovery unit, and further comprising humidity measurement means of measuring the humidity in the feed channel and a controller for controlling the amount of water to be added by the water adding means, is characterized in that the controller controls the amount of water to be added by the water adding means, according to the measurement result measured by the humidity measuring means.SELECTED DRAWING: Figure 1 【課題】回収する溶剤を従来よりも正確に希釈することができる溶剤回収システムを提供することを目的としている。【解決手段】溶剤を含むガスを冷却部に供給する供給路と、前記供給路から供給された前記溶剤を含むガスを冷却し、前記溶剤を液化させる前記冷却部と、液化した前記溶剤を回収する回収部と、前記回収部により回収される前記溶剤を希釈するための水分を加える水分付与手段と、を備える溶剤回収システムであって、前記供給路内の湿度を測定する湿度測定手段と、前記水分付与手段により付与する水分の量を制御する制御部と、をさらに備えており、前記制御部は、前記湿度測定手段による測定結果に基づいて、前記水分付与手段により加える水分の量を制御する構成とする。【選択図】図1
