Chlorine dioxide gas sustained-release device and manufacturing method thereof

Abstract

The invention discloses a chlorine dioxide gas sustained-release device and a manufacturing method thereof. At a cooling low temperature, ready-made chlorine dioxide gas is adsorbed by carriers so as to make chlorine-dioxide-gas-contained solid carriers, the solid carriers are quantitatively subpackaged in good-quality, airtight and opaque containers in small quantity, so that the chlorine dioxide gas products which are lightweight and portable, are safe and easy to carry, can be stored for a long term, and can be taken at any time are formed, and the excellent industrial economic benefits are formed.

Description

technical field [0001] The invention relates to a chlorine dioxide gas slow release device and its manufacturing method, especially to a method for absorbing chlorine dioxide gas on a carrier to provide slow and long-term release and its product. Background technique [0002] Chlorine dioxide (ClO 2 ) is a strong oxidant with high-efficiency disinfection and bactericidal effects. It has been internationally recognized as a bactericidal disinfectant and water purifier with excellent performance and very effective effects, and the World Health Organization has listed chlorine dioxide as A1-level high-level safety disinfectant. [0003] Due to the presence of chlorine dioxide liquid preparations, chlorine dioxide gas is unstable and easy to decompose, and its storage, transportation and use are subject to many restrictions. Therefore, solid chlorine dioxide (i.e. commonly known as stable chlorine dioxide) ) methods are mainly divided into two categories: [0004] 1. For the ...

Problems solved by technology

[0007] Because the above-mentioned method has its shortcoming in the application that obtains gaseous chlorine dioxide, be exactly the by-product that reaction generates and remain unreacted organic matter and inorganic matter, can cause chlorine dioxide gas (ClO 2 ) reacts rapidly with oxidizable substances in water to produce chlorite (ClO 2 - ), chlorate (ClO 3 - ) and chloride salts (Cl - ), rather than the chlorine dioxide gas molecule (ClO 2 )

[0008] In the market, in addition to the above-mentioned stable chlorine dioxide products, there are also chlorine dioxide aqueous solution products on the market, such as U.S. Patent No. 5,296,108 and No. 5,993,864 patents. These products still have many other problems and deficiencies , explained as follows: (1) General traditional manufacturers, no matter by electrolytic method or chemical method, dissolve chlorine dioxide in the water body and transport or store it in the form of aqueous solution. The disadvantage is that chlorine dioxide gas will be released in the water body Decays unstable, rapidly decomposing into ClO 2 - , ClO 3 - and Cl - various anionic forms

(2) Place the equipment of the electrolysis method at the place of the user, and start the equipment to produce the chlorine dioxide aqueous solution when it is used on the spot, which is convenient to use immediately. Easy to use by the general public

(3) Utilize the chemical method at the time and place of use, still on-site manufacturing and use, put various chemical reagents mixed into the water body, and react in the water to produce an aqueous chlorine dioxide solution. The disadvantage is that attention must be paid to avoid being too intense Residual chemical substances and by-products of incomplete reaction will remain in the reaction and aqueous solution
