PROBLEM TO BE SOLVED: To provide an anesthetic gas recovery device capable of efficiently recovering an anesthetic from a gas to be processed, which is used to kill small animals at an animal custody center or the like and contains moisture and a high-concentration anesthetic gas, and liquefying the anesthetic so that the anesthetic can be reused.SOLUTION: An anesthetic gas recovery device A includes a compressor 1 that compresses a gas to be processed, a preliminary cooler 2 that preliminarily cools the gas to be processed which has been compressed by the compressor 1, a first recovery container 3 that recovers an anesthetic solution and water, which result from condensation in the preliminary cooler 2, so that the anesthetic solution and water can be layered to be a lower layer and upper layer respectively, a cooler 4 that cools a residual gas resulting from processing in the preliminary cooler 2, a second recovery container 6 that recovers the anesthetic solution and water, which result from condensation in the cooler 4, over a solution feeding path R6 having a valve 7 so that the anesthetic solution and water can be layered, a chiller unit 5 serving as a cooling heat source for the preliminary cooler 2 and cooler 4, and an exhaust path R5 over which a processed gas cooled by the cooler is discharged.COPYRIGHT: (C)2015,JPO&INPIT【課題】動物管理センター等で小動物の殺処分に使用された、湿分と高濃度の麻酔性ガスを含む被処理ガスから、麻酔剤を効率よく回収して、再利用できるように液化することができる麻酔性ガス回収装置を提供する。【解決手段】麻酔性ガス回収装置Aは、被処理ガスを圧縮する圧縮機1と、圧縮機1で圧縮された被処理ガスを予備的に冷却する予冷却器2と、予冷却器2で凝縮によって得られた麻酔液と水を下層が麻酔液で上層が水である層を成して回収する第1の回収容器3と、予冷却器2で処理した残ガスを冷却する冷却器4と、冷却器4で凝縮によって得られた麻酔液と水をバルブ7を有する送液経路R6を介し、層を成して回収する第2の回収容器6と、予冷却器2と冷却器4の冷熱源であるチラーユニット5と、冷却器4で冷却処理した処理済ガスを放出する排気経路R5とを備えている。【選択図】図1
