Abstract

The invention discloses a method and equipment for preparing high-purity chlorine dioxide at high conversion rate, accurately controlling chlorine dioxide adding amount, and greatly enhancing the reliability of system operation at the same time. The invention aims to solve the main technical problems that the conversion rate and the purity of the chlorine dioxide are improved, the chlorine dioxide adding is accurately and dynamically controlled, and the reliability and the safety of the system operation are enhanced. In the invention, sulphuric acid, sodium chlorate and a hydrogen peroxide solution are heated, and are subject to gas-liquid separation after being mixed through a Venturi mixer; the adding amount and the adding proportion of a prepared chlorine dioxide gas are accurately controlled by an intelligent environmental adaptation system for multipoint adding, so as to ensure the water quality reaches the standard. The chlorine dioxide preparing and adding equipment of the invention can carry out remote real-time centralized control and management, so that the reliability and the safety of the system operation are greatly enhanced. The invention has the advantages of high conversion rate of preparing the chlorine dioxide, high purity, low disinfection cost, as well as safe and reliable system operation, thereby facilitating centralized management and large-scale promotion.

Description

technical field

[0001] The invention relates to a method and equipment for preparing and adding disinfectant for drinking water, in particular to a method and equipment for preparing high-purity chlorine dioxide with high conversion rate and precisely controlling the dosage of chlorine dioxide. Background technique

[0002] In the past thirty years, chlorine dioxide, as a new type of disinfection oxidant, has been widely used in developed countries, and it is an excellent disinfection oxidant to replace liquid chlorine. The water treated with chlorine dioxide will not produce the carcinogen trihalomethanes that are usually formed when chlorine gas is used for disinfection. Its safety is listed as AI level by the World Health Organization (WHO). , long drug effect, bactericidal effect is not limited by PH value and many other advantages, the killing rate of some bacteria can reach 100%; the use of chlorine dioxide disinfection can also oxidize some reducing metal ions in wate...
