Description

Technical Field

[0001] The utility model relates to the technical field of sodium hypochlorite processing equipment, in particular to a sodium hypochlorite configuration device. Background Art

[0002] Sodium hypochlorite is an inorganic compound that is often used in disinfection and cleaning work in daily life. Its chemical properties are relatively active, capable of reacting with acids to produce toxic chlorine gas and easily decomposing under light. This substance has a wide range of applications in various industries. For example, in the bleaching processes of pulp, textiles, and chemical fibers, as well as in water treatment as a water purifying agent, bactericide, and disinfectant. Sodium hypochlorite can also be used to manufacture dyes such as sulfur blue and organic industrial chemicals such as chloropicrin. Sodium hypochlorite not only plays an important role in industrial production but is also widely used in the agricultural and food industries. In agriculture, it can be used as a disinfectant and deodorant for vegetables, fruits, breeding farms, and livestock houses. In the food industry, food-grade sodium hypochlorite is used for the disinfection of drinking water, fruits, and vegetables, as well as the sterilization and disinfection of food manufacturing equipment and utensils. When configuring sodium hypochlorite, it is necessary to react diluted sodium hydroxide solution with chlorine gas.

[0003] Currently, before configuration, during the production of sodium hypochlorite, the temperature of the sodium hydroxide solution needs to be controlled and cooled to a temperature suitable for reaction with chlorine gas. When cooling and transporting the diluted sodium hydroxide solution currently, although it is soaked in cooling water, a rapid cooling method still cannot be provided, which is not conducive to actual configuration and use.

[0004] Therefore, it is necessary to provide a sodium hypochlorite configuration device to solve the above technical problems. Summary of the Utility Model
