PROBLEM TO BE SOLVED: To provide a decontamination system using hydrogen peroxide capable of shortening a time for detoxifying the hydrogen peroxide.SOLUTION: A decontamination system using hydrogen peroxide includes a decontamination apparatus 20 and a detoxification device 40. The decontamination apparatus 20 is equipped with a nozzle 24 for spraying an aqueous solution of hydrogen peroxide, a compressor 26 for supplying the nozzle 24 with compressed air, and a warm air generator 28 for injecting warm air to a mist of the hydrogen peroxide sprayed from the nozzle 24. The detoxification device 40 is equipped with a catalyst 42 for detoxifying the hydrogen peroxide and a detoxification fan 44 for letting room air pass through the catalyst 42. A control unit 36 controls the system so that the compressor 26 and the warm air generator 28 are operated to evaporate the hydrogen peroxide in the decontamination step and that the compressor 26 is stopped and the detoxification fan 44 of the detoxification device 40 is started continuing the operation of the warm air generator 28 in the detoxification step after the decontamination step.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】過酸化水素の除害に要する時間を短縮することができる過酸化水素除染システムの提供。【解決手段】過酸化水素水溶液を霧状に噴霧するためのノズル24、ノズル24に圧縮空気を供給する圧縮機26、ノズル24から噴霧された霧状の過酸化水素に温風を噴射する温風発生装置28、を有する除染装置20と、過酸化水素を除害する触媒42、及び触媒42に室内空気を通過させるように空気を流通させる除害用ファン44を有する除害器40とを具備し、除染装置20は、除染工程時には、圧縮機26及び温風発生装置28を駆動させて過酸化水素を蒸発させ、除染工程終了後の除害工程時には、圧縮機26を停止させ、温風発生装置28は駆動したまま除害器40の除害用ファン44の駆動を開始する制御部36を有する過酸化水素除染システム。【選択図】図1
