  • Patent number: 10239032
    Abstract: The present invention provides a chlorine dioxide generation unit that can release practically sufficient amount of chlorine dioxide for an extended period of time while being compact. The present invention provides a chlorine dioxide generation unit, characterized in that said unit comprises an agent storage space portion and at least two light source portions, said light source portion is for generating light consisting of wavelengths substantially in the visible region, said agent storage space portion stores an agent comprising solid chlorite, and said agent storage space portion comprises one or more openings so that air could move in and out of said agent storage space portion, wherein chlorine dioxide gas is generated by irradiating said light generated from said light source portion onto said agent present inside said agent storage space portion.

  • Patent number: 9315911
    Abstract: An electrolyzer apparatus includes an anode tank having an anode and a cathode tank having a cathode which are provided separately from each other. The anode tank includes a feed opening for feeding electrolytic solution into the tank, an anode aeration device for feeding aeration air to the fed electrolytic solution, and a gas extraction pipe for guiding gas generated from the anode tank to outside the tank. A communication pipe allows the amount of electrolytic solution fed into the anode tank to flow into the cathode tank, and via the electrolytic solution in the communication pipe, electric conduction becomes possible between the anode and the cathode. An amount of gas generated by an electrolysis reaction inside the anode tank is discharged to the outside of the anode tank via the gas extraction pipe together with the aeration air. The electrolytic solution introduced into the cathode tank is discharged continuously.
