Abstract

The invention relates to the production of chlorine-containing oxidants used as reagents in the decontamination and purification of drinking water, and specifically to the production of an aqueous solution of a mixture of chlorine dioxide and chlorine. The technical problem addressed is that of reducing the energy consumption and increasing the stability of the hydrodynamic regime of the apparatus. The problem is solved in that the method for producing a solution of chlorine dioxide and chlorine is realized by reacting a solution of sodium chlorate and sodium chloride with highly concentrated sulphuric acid and using a low-density atmosphere to remove the resultant vapour-liquid mixture of chlorine dioxide, chlorine and sodium sulphate solution from the reaction zone. The concentration of sodium sulphate is kept lower than the saturation level of the reaction medium, and an absolute pressure of 22-100 kPa is generated in the reaction zone. In order to realize the method, an apparatus is used which comprises a housing with pipes situated in the lower part thereof for introducing the reagents, and a pipe for removing the gaseous products and spent aqueous solution, which is situated in the upper part of the housing and communicates with an ejector connected to the apparatus. A circulating device in the form of a cowl is coaxially secured to the housing, and the pipes for introducing the reagents are situated in the end part of the housing, pass inside the circulating device and are coaxial with the axis of the housing.
