Description
本発明にて使用する第1実施形態に係る処理ガス発生装置1の外観は、図1に示すように、装置側面部に処理ガス供給管2を備え、装置前面部には、処理ガスの濃度、温度、処理時間、処理ガス流量等を設定するための各種操作子3や状態表示器4が設けられている。
本発明では、上記した処理ガス発生装置1に代えて、さらに処理対象区域から有機化合物を分解処理した後の排ガスを排出するガス排出系40を設けた処理ガス発生装置1´を用いてもよい。この第2実施形態に係る処理ガス発生装置1´の外観は、図4に示すように、装置側面部に処理ガス供給管2と排ガス排出管5とを備え、装置前面部に処理ガスの濃度、温度、処理時間、処理ガス流量等を設定するための各種操作子3や状態表示器4を備えている。この処理ガス発生装置1´は、処理対象区域が閉鎖空間のときに効果的である。なお、第1実施形態に係る処理ガス発生装置1と同一の構成には同じ符号を付す。
また、本発明に係る方法では、処理ガスとして、メタノールガスに触媒を作用させることにより発生するヒドロキシルメチルラジカル、ヒドロペルオキシラジカル、水素ラジカル、ヒドロキシルラジカルを使用しており、かかる処理ガスには腐食性、残留性がないため、除染装置の劣化が少なく、装置のメンテナンスが簡易である。また、処理ガスの安全性が高いため、人員除染、武器・車両等の装備品除染、道路等の地域除染、ビル・地下鉄等の施設除染、精密器材除染等のあらゆる対象物への除染が可能である。
・ガス捕集管:TENAX捕集管(GLサイエンス(株)製)
・処理ガス発生装置:メタノールラジカルガス(MR)発生装置((株)ウイングターフ社製)
・暴露条件:温度20℃、湿度90%

Claims (3)
- VEガス、VGガス、VMガス、VXガス、サリン、エチルサリン及びシクロサリンからなる群から選択される有機化合物を処理ガスに常温で暴露することにより除染する方法であって、前記処理ガスが、メタノールガスに触媒を作用させることにより発生するヒドロキシルメチルラジカル、ヒドロペルオキシラジカル、水素ラジカル、ヒドロキシルラジカルを含むことを特徴とする、除染方法。
- 前記有機化合物が、大気中に拡散した気体であることを特徴とする、請求項1に記載の除染方法。
- 前記有機化合物を多孔質体に吸着させて除染することを特徴とする、請求項1又は2に記載の除染方法。
