An efficient electrolysis system for sodium chlorate production may include round or oval cells, reactors, a product pump transfer, a buffer tank, a circulation pump, and explosive clad plate, all of which are connected by way of pipelines. Inlet and the outlet of each cell are separately connected with the reactor via titanium pipes, allowing the electrolyte to recirculate naturally between the cells and the reactors. The outlet of every cell is conical while each reactor includes a standard electrolytic unit with three to eight cells. The electrolytic units are modularly identical and symmetrically linked to the buffer tank. Within each unit, adjacent cells are connected with the explosive clad plates. The buffer tank may be divided into two parts&#x2014;part A and part B&#x2014;with part A connecting with the overflow port of the reactor via pipeline, and the part B connecting with the reactor via the circulation pump. Part B is equipped with a refined brine feed pipe on the top, the bottom of part A connects with a product transfer pump () via pipeline.

Efficient electrolysis system for sodium chlorate production

A system for the integral chlorine dioxide production with relatively independent sodium chlorate electrolytic production and chlorine dioxide production is provided. The system may feed electrolyte solution into a solid-liquid filter, filtering out the crystal and eliminating sodium chloride and sodium dichromate. The sodium chlorate crystal may be fed into a chlorine dioxide generator after dissolving, while sodium chloride and sodium dichromate solution separately return to electrolyzer for electrolysis process. Sodium chloride may be constantly formed as a by-product in the chlorine dioxide production unit, and solution containing the sodium chloride is withdrawn from the generator and, after filtration, washing and dissolution, recycled back to sodium chlorate production unit. This way, there is no need of sodium chloride make-up.
