摘要：
PROBLEM TO BE SOLVED: To provide a sterilizing gas purifying closed system capable of performing a sterilizing treatment with a cheap structure.SOLUTION: A gas piping 37 connected to a use area 30 via a first opening 35 opened or closed by opening or closing a first valve and a catalyst area 31 connected to the use area via a second opening 36 opened or closed by opening or closing a second valve are provided, a sterilizing gas is a hydrogen peroxide gas, in the catalyst area, platinum/palladium is provided as the catalyst, during sterilization, by closing the second valve and by opening the first valve, hydrogen peroxide gas is introduced into the use area from the gas piping via the first opening, after introduction, the first valve is closed to make the use area a closed state to perform a sterilization treatment with the hydrogen peroxide gas, after a predetermined time, the first valve and the second valve are opened, via the first opening, a harmless gas is introduced from the gas piping to purify the hydrogen peroxide gas in the form of extruding the hydrogen peroxide gas in the use area into the catalyst area.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】安価な構成で滅菌処理が可能な滅菌ガス浄化閉鎖系装置の提供。【解決手段】使用エリア３０に第１の弁を開閉することで解放または閉鎖される第１の開口３５を介して接続されるガス配管３７と、使用エリアに第２の弁を開閉することで解放または閉鎖される第２の開口３６を介して接続される触媒エリア３１を有し、滅菌ガスは過酸化水素ガスであって、触媒エリアには触媒として白金パラジウムが備えられており、滅菌処理時には、第２の弁を閉じ第１の弁を開き過酸化水素ガスが第１の開口を介してガス配管から使用エリアに導入され、導入後、第１の弁を閉じ使用エリアを密閉状態として過酸化水素ガスによる滅菌処理を行い、所定時間後、第１の弁および第２の弁を開き第１の開口を介してガス配管から無害な気体を導入することで使用エリア内の過酸化水素ガスを触媒エリアに押し出す形で導入し過酸化水素ガスを浄化する。【選択図】図５
