METHOD OF PRODUCTION OF THE CHLORINE DIOXIDE SOLUTION AND CHLORINE IN THE WATER AND THE REACTOR FOR ITS REALIZATION Russian patent published in 2007 - IPC C01B11/02 B01J19/18 

FIELD: chemical industry; methods and devices for production of the chlorine dioxide solution and chlorine in the water.

SUBSTANCE: the invention is pertaining to the method of production of the chlorine-containing oxidizers used at decontamination and purification of the drinking water, sewage and the recycled waters. Production of the chlorine dioxide solution and chlorine in the water is exercised by interaction of the following reactants: the solution of sodium chlorate and sodium chloride with the sulfuric acid in the multi-chamber reactor at the reactor efficiency of no more than 4 g/h per 1 cm² of the reactor cross-section. The reactants are fed into the lower chamber of the reactor. Reactants give to an after bay of the choke. The water used for absorption and removal of the chlorine dioxide and chlorine from the reactor is fed into the upper chamber of the reactor. Process is realized in the reactor (1) including no less than two chambers, which are made flow-through and located which one are fulfilled flow, are allocated sequentially in vertical direction and are divided by partitions (2, 3, 4) with foramens. In the upper chamber (8) there are the fitting pipes (12, 13) used for the water delivery and withdrawal. In the lower chamber (11) there are fitting pipes (14, 16) used for the reactants feeding and the fitting pipe (15) for discharge the reactionary solution.

EFFECT: the invention ensures the effective production of the chlorine-containing oxidizers used at decontamination and purification of the drinking water, sewage and the recycled waters.
