PROBLEM TO BE SOLVED: To provide a chlorine dioxide gas generator which reduces mixing of acidic mist and allows taking out of chlorine dioxide gas at a low humidity.SOLUTION: A chlorine dioxide gas generator 1 is for generating chlorine dioxide gas d by supplying a chlorite solution a and an acidic solution b to a closed reaction vessel 10 to cause a chemical reaction of the solutions a and b and includes a suction tube 50 which is opened above the liquid surface of the mixed solution c of the chlorite solution a and the acidic solution b reserved in the bottom of the reaction vessel 10 and takes air into the reaction vessel 10 and a discharge tube 51 which is opened above the liquid surface of the mixed solution c of the chlorite solution a and the acidic solution b reserved in the bottom of the reaction vessel 10 and discharges outside the chlorine dioxide gas d generated in the reaction vessel 10. Since the chlorine dioxide gas d is taken out from the reaction vessel 10 without aeration into the mixed solution, mixing of acidic mist is reduced, and the chlorine dioxide gas d can be taken out at a low humidity.COPYRIGHT: (C)2015,JPO&INPIT【課題】酸性ミストの混合が少なく低湿度で二酸化塩素ガスを取り出すことができる二酸化塩素ガスの発生装置を提供する。【解決手段】密閉された反応容器10に亜塩素酸塩溶液aと酸性液bを供給し、両者の化学反応によって、二酸化塩素ガスdを発生させる二酸化塩素ガス発生装置1であって、反応容器10の底部に溜められた亜塩素酸塩溶液aと酸性液bの混合溶液cの液面よりも上方において開口した、反応容器10に空気を取り入れる吸込み管50と、反応容器10の底部に溜められた亜塩素酸塩溶液aと酸性液bの混合溶液cの液面よりも上方において開口した、反応容器10内で発生させた二酸化塩素ガスdを外部に吐出する吐出管51を備える。二酸化塩素ガスdを混合溶液中に曝気(エアレーション)することなく反応容器10から取り出しているので、酸性ミストの混合が少なく低湿度で二酸化塩素ガスdを取り出すことができる。【選択図】図1
