Energy-efficient diaphragm-electrolyser

摘要

The invention relates to the field of electrochemical production of disinfectants, where a solution of alkaline metals is used as the electrolyte in the anode chamber. The invention offers a new design for electrolysers, reducing power consumption in the production of disinfectants by known methods. As a result of this invention, power consumed in the production of 1 gram of active chlorine by known methods will be reduced by 20%, and the possibilities for producing disinfectants with active chlorine content 7500 ppm in an electrolyser without channelling the water into external cooling devices will also expand.

主权项

1) A diaphragm electrolyser comprising a tubular cathode, an anode, a cylindrical diaphragm, and an upper cover and a lower cover, wherein
in the electrolyser an inflow of water to be mixed with concentrated anolyte is allowed in the upper cover, and wherein:
the cathode forms a tubular inner electrode, said electrode having a lower end and an upper end and being sealed with the lower cover from the lower end and with the upper cover from the upper end;the upper cover having a water inlet opening and a disinfectant outflow opening on a same axis on opposite sides of the upper cover and being interconnected with a straight channel, the lateral surface of which is tangential in relation to the cylindrical surface of the diaphragm; andat least one of the covers of the cathode is made of current conductive material, and is fitted with a terminal and transfers voltage to the cathode and by its measurements with the terminal included is smaller or equal with the external diameter of the cathode.
