  • Publication number: 20140086821
    Abstract: A chlorine dioxide generator includes a container body deformable in response to application of a force from the outside. The container body contains therein a solid acidic composition and an aqueous chlorite solution under a non-contact state from each other. The solid acidic composition comprises a porous material containing an acidic substance. The aqueous chlorite solution is sealed within an easily breakable enclosure. In operation, when the container body is deformed, the enclosure contained therein is broken to bring the aqueous chlorite solution into contact with the solid acidic composition, whereby chlorine dioxide gas is generated. This generated chlorine dioxide gas is discharged via a gas discharge port to the outside of the container body.

  • Patent number: 8652411
    Abstract: A device for generating chlorine dioxide includes a cartridge having a chemical-holding space, in which a granular chlorite is held, a fan, and ultraviolet LED lamps disposed within a device main body, which can be separated into two or more detachable portions. The cartridge has light-transmitting properties and has a structure, which enables air to pass through the chemical-holding space and the inside of the device main body. When the fan is in operation, air is discharged from the inside of the device main body and, simultaneously therewith, air comes in from the outside of the device main body. By the action of ultraviolet rays, chlorine dioxide gas is generated from the chlorite present in the cartridge. By the operation of the fan, the gas is discharged from the inside of the device main body through air discharge ports.

  • Publication number: 20130043126
    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.

  • Publication number: 20110183004
    Abstract: The invention provides a measure that can readily prevent arthropod-borne diseases such as malaria that are contracted by 3 to 5 hundred million people worldwide yearly and that cause death of as many as 1.5 to 2.7 million people. By spraying in advance on the skin an arthropod-borne disease preventive agent or the like comprising chlorine dioxide as an effective component thereof, it is possible to provide repelling effect against arthropods such as infected mosquitoes that bear malaria protozoa and also to prevent biting of the skin by the arthropod, thus reducing contraction of the arthropod-borne diseases.
