Description

Chlorine dioxide gas generator {APPARATUS FOR GENERATING CHLORINE DIOXIDE}

The present invention relates to a chlorine dioxide gas generator, and more particularly, to a chlorine dioxide gas generator for continuously and stably generating chlorine dioxide gas used for odor removal and the like.

Odor reduction facilities or general discharge facilities discharge air to the atmosphere or through dedicated dust collection and treatment facilities using air circulation devices and other equipment for various purposes such as ventilation and reduction of odors and dust inside. On the other hand, it is often the case that the performance of the treatment facility is deteriorated due to adhesion, adhesion or clogging due to the characteristics of the substances contained in the air, and various symptoms.

Therefore, as a means for removing the odor, _{research on a method using chlorine dioxide (ClO 2} ) gas is in progress. Chlorine dioxide is an excellent substance for sterilization and odor removal due to its strong oxidizing power by oxygen, and is used for various purposes such as toxic inorganic substance removal, heavy metal removal, sterilization and disinfection, clothing bleaching, and odor removal. This chlorine dioxide has about 25 times stronger oxidizing power than latex, and has a strong deodorizing and sterilizing action without irritating odor. disassemble

As described above, in order to effectively remove odors and the like by oxidation and decomposition, it is necessary to continuously and stably produce and supply the chlorine dioxide gas.
