Abstract

The invention discloses a high-efficiency sodium chlorate electrolysis system. The high-efficiency sodium chlorate electrolysis system is characterized in that the system comprises electrolysis tanks (1), a reactor (2) and a buffer tank (4), and an inlet and an outlet of each electrolysis tank (1) are connected with the reactor (2) through titanium tubes independently. By the adoption of the round or oval electrolysis tanks, electrolytes in the tanks flow sufficiently, the inlet and the outlet of each electrolysis tank are connected with the reactor through the titanium tubes independently, independent natural circulation is achieved, circulation is more sufficient, and the problem that electrolysis tanks are different in electrolyte inlet amount due to the fact that a traditional sodium chlorate electrolysis system adopts one electrolyte inlet header pipe to supply electrolytes to the electrolysis tanks is solved; and the two rows of electrolysis tanks are distributed symmetrically and more compactly, and a sodium chlorate preparation production line can achieve flexible combination according to the capacity requirement.

Description

technical field [0001] The invention relates to the field of sodium chlorate electrolysis, in particular to an efficient sodium chlorate electrolysis system. Background technique [0002] The chemical formula of sodium chlorate is NaClO 3 , relative molecular mass 106.44. Usually white or yellowish equiaxed crystals. Taste salty and cool, soluble in water, slightly soluble in ethanol. It has a strong oxidation effect in acidic solution and decomposes oxygen above 300°C. Sodium chlorate is unstable, and it is easy to burn and explode when mixed with phosphorus, sulfur and organic matter, and it is easy to absorb moisture and agglomerate, and is poisonous. Sodium chlorate has a wide range of uses. It is mainly used in the manufacture of chlorine dioxide in industry. In the printing and dyeing industry, it is used as an oxidant for dyeing refined fabrics, and can also be used as a dye. It is used as an oxidizing agent in the inorganic industry, and can also be used in the ...
