Problems solved by technology

However, because chlorine dioxide is unstable and highly corrosive, it is not easy to store and transport. Therefore, the development of equipment that can be prepared on-site and used on-site has become a prerequisite for using chlorine dioxide to disinfect water bodies that are continuously supplied.

Abstract

The invention discloses a chlorine dioxide production device for water disinfection, which comprises a sodium chlorite aqueous solution adding unit, a hydrochloric acid adding unit, a reaction kettle and a control device, and the sodium chlorite aqueous solution adding unit and the hydrochloric acid adding unit respectively comprise a raw material barrel, a connecting pipeline and a metering pump, a metering pump sucks the raw materials in the raw material barrels of the feeding units through a connecting pipeline and feeds the raw materials into the reaction kettle; the two feeding units adopt the raw material barrels with the same shape and specification, and the initial liquid level values of the sodium chlorite aqueous solution and the hydrochloric acid are the same; the sodium chlorite aqueous solution and the hydrochloric acid are added according to a preset volume ratio of 1: 1, and chlorine dioxide generated by reaction in the reaction kettle and reaction residual liquid are added into a water body to be disinfected in real time in the form of a disinfectant. The device is simple in structure, reliable in work and low in requirements on working conditions, and creates conditions for applying chlorine dioxide to water disinfection of small water occasions.

Description

technical field [0001] The invention relates to a chlorine dioxide production device for water body disinfection. Background technique [0002] Liquid chlorine has been widely used in water supply disinfection treatment process, but chlorine disinfection will produce trihalomethanes (THMs), haloacetic acids (HAAS) and other "three causes" substances (cancer, teratogenic and mutagenic), therefore, people Start disinfecting water supplies with chlorine dioxide instead of liquid chlorine. However, because chlorine dioxide is unstable and highly corrosive, it is not easy to store and transport. Therefore, the development of equipment that can be prepared and used on site has become the premise of using chlorine dioxide to disinfect water bodies with continuous water supply. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a chlorine dioxide production device for water disinfection suitable ...
