METHOD OF SYNTHESIS OF OXIDIZERS FROM THE WATER SOLUTION OF SODIUM CHLORIDE AND A DEVICE FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: chemical industry.

SUBSTANCE: the invention is dealt with electrochemical unipolar treatment of the liquid mediums, that renders them widely controlled stable and metastable properties of disinfectant solutions that may be used in the most different spheres of human activity at lowering the environmental pressure on the nature. The method provides feeding into the diaphragm electrolyzer anodic chamber of an water solution of Sodium chloride with concentration of 1-3 g/l. The caustic soda solution with concentration of no less than 100 g/l is fed into the cathodic chamber, pumped through its circulation contour with a speed providing a minimum percentage of gases in the cathodic chamber. At that consumption of the water component the caustic soda solution is replenished with supply of pure water into the cathodic contour. The method is realized in the device, which contains a diaphragm electrolyzer, the anodic chamber of which has an inlet for a solution of Sodium chloride and an outlet for a solution of oxidizers, and the cathodic chamber is supplied with a circulation contour. The circulation contour of the cathodic chamber is filled with the caustic soda solution with concentration of no less than 100 g/l. At that the circulation contour has a container filled with a concentrated solution of caustic soda. The container has a branch-pipe supplied with a valve for a makeup pure water supply of a cathodic contour, and also is supplied with a device for speed control of circulation of a the caustic soda solution flow. The device for speed control of circulation of a the caustic soda solution flow contains a pressure pump. The technical result - a decrease of corrosive action caused by fed solution of oxidizers, reduction of consumption of power and salt per a unit of a produced oxidizer.

EFFECT: the invention allows to decrease corrosive action caused by fed solution of oxidizers, to reduce consumption of power and salt per a unit of a produced oxidizer.
