Description

Powder Chlorine Dioxide Activation Spraying Device

technical field

The utility model relates to a preparation and spraying device using powdered chlorine dioxide as a disinfectant raw material in aquaculture, and belongs to the technical field of aquaculture disinfection.

Background technique

Chlorine dioxide is an excellent oxidizing bactericidal disinfectant with broad-spectrum bactericidal function. Its oxidizing ability is 2.6 times that of chlorine, and its ability to inhibit viruses is 3 times higher than that of chlorine. Its bactericidal persistence is 10 times that of chlorine. Above, chlorine dioxide reacts with organic substances such as humic acid and fulvic acid in water without generating carcinogens such as trihalomethanes, and is listed as a grade A1 safe disinfectant by the World Health Organization. At present, the aquaculture industry widely uses chlorine dioxide, especially powdered chlorine dioxide activated reaction disinfectant, to disinfect water in aquaculture waters. When using it, the powdered chlorine dioxide is often first activated in a container next to the pond or in a small pool. Then spray in the pond, the activated chlorine dioxide exposed in the container or small pool is easy to volatilize and decompose, and about half of the remaining activated chlorine dioxide sprayed on the water surface is difficult to effectively disinfect the water at the bottom. In addition, activated chlorine dioxide has severe irritation and damage to human beings during the volatilization and decomposition process. Therefore, we should try to solve the problems of volatilization, waste and stimulation damage during the activation of powder chlorine dioxide.
