Unit for chlorine dioxide generation and chlorine dioxide generation device

A method of producing chlorine dioxide involves generating chlorine dioxide gas by deforming a container body of a chlorine dioxide generator which is deformable in response to application of a force to the container body from outside of the container body. The deforming of the container body causes an enclosure contained in the cylinder body to be broken to bring an aqueous chlorite solution into contact with a solid acidic composition to generate chlorine dioxide gas that is discharged via a gas discharge port of the container body to outside of the container body. The method additionally involves submerging in water at least the gas discharge port of the container body during the generation of the chlorine dioxide gas to dissolve the chlorine dioxide gas discharged via the gas discharge port in the water.

A method of entrapping chlorine dioxide gas, including the steps of using an aqueous solution containing an alkaline substance and an iodide and bringing air containing the chlorine dioxide gas into contact with the aqueous solution.

Method of entrapping chlorine dioxide gas, method of determining concentration of chlorine dioxide and entrapping agent for chlorine dioxide

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.

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.

Electrolyzer apparatus

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.

Device for generating chlorine dioxide

There are provided a chlorine dioxide solution composition whose solute includes dissolved chlorine dioxide and chlorite; and a solution composition encapsulating body including a glass vessel or enameled vessel and the chlorine dioxide solution composition hermetically sealed therein.
