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.

Chlorine dioxide production device and chlorine dioxide production method

A portable intake air sterilizing apparatus is disclosed, which allows prevention of a worker's infection with virus/bacteria and which can allow, at the same time, the worker to work comfortably. The apparatus includes a cover member C for covering one or both of the nose and the mouth, an air intake portion K for the inner space of the cover member C, and a chlorine dioxide slow-release portion J capable of releasing chlorine dioxide gas into an intake air in association with introduction of this intake air from the air intake portion K.

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.

There is provided a portable intake air sterilizing apparatus which allows prevention of a worker's infection with virus/bacteria and which allows, at the same time, the worker to work comfortably. The apparatus includes a cover member C for covering one or both of the nose and the mouth, an air intake portion K for the inner space of the cover member C, and a chlorine dioxide slow-release portion J capable of releasing chlorine dioxide gas into an intake air in association with introduction of this intake air from the air intake portion K.

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.
