Technical Field

The invention relates to the technical field of disinfectants, and discloses a chlorine dioxide generating device which is composed of a solid chlorite, delignified wood, polyethylene glycol and an acid mist manufacturing tank.

Background

Chlorine dioxide is gaseous at normal temperature, very easily dissolves in water and does not react with water, and the solubility in water is 5 ~ 8 times of chlorine, and hardly takes place to hydrolyze. Chlorine dioxide has a strong oxidizing property, and its available chlorine is 2.6 times that of chlorine gas, and therefore, it is commonly used as an oxidizing agent, a deodorizing agent, a biocide, an antistaling agent, a bleaching agent, etc.

The chlorine dioxide can well play roles of deodorization, disinfection, sterilization and bleaching no matter in a gaseous state or in an aqueous solution, the disinfection effect of the chlorine dioxide disinfectant is enhanced along with the increase of the concentration, the candida albicans is killed by using 500ppm of the chlorine dioxide disinfectant solution for 1min, and the killing rate reaches 100%; when 250ppm is used, the effect is performed for 10min, and 99.99 percent can be achieved.

However, the volume concentration of chlorine dioxide in the air is more than 10%, so that the explosion risk exists, and the concentration of chlorine dioxide in the environment is more than 5ppm, so that the chlorine dioxide has obvious toxic action on a human body. Thus, chlorine dioxide is generally not suitable for storage in gas cylinders, and storage in solution also presents a potential hazard due to the ease of leakage.

Therefore, chlorine dioxide is generally used in a manner that is currently available, and a solid chlorine dioxide releasing agent is used. However, most common chlorine dioxide solid releasing agents in the market at present cannot well control the release rate of chlorine dioxide or ensure long-term effective concentration, and are easy to crack and pulverize in the transportation process and difficult to store.
