Abstract

本発明の有機溶剤回収システムは、キャリアガスを循環させる循環経路と、導入用経路からの被処理ガスに含有された有機溶剤を吸着する吸脱着素子を備えた吸脱着処理装置と、キャリアガス中の有機溶剤を凝縮させる凝縮回収装置と、キャリアガスを加熱する加熱部と、導入用経路を通流する被処理ガスの一部を吸脱着素子の冷却用に導入する冷却用経路と、吸脱着素子の冷却に用いた被処理ガスを導入用経路へ戻す返却用経路と、を備え、吸脱着処理装置は、導入用経路からの被処理ガスの導入により吸脱着素子にて吸着を行った後、加熱されたキャリアガスを導入して脱着を行い、その後に、冷却用経路からの被処理ガスの導入により吸脱着素子を冷却し、その後再び、導入用経路からの被処理ガスの導入により吸着を行い、凝縮回収装置は、キャリアガスの冷却にて凍結した成分を一時的に加熱して融解させる融解部を有する。
