ABSTRACT:
An electrochemical cell for electrolytic treatment of aqueous solutions, particularly for cyanide detoxification or oxidation, has a solution container with a cell housing mounted on it, in which an electrode stack is located. Solution is delivered to the cell housing in the region of its housing bottom by a circulation device, and after passing through the electrode stack by an overflow over the side walls of the cell housing, is delivered to a cascadelike drain container with its own overflow for the sake of degassing; after passing through the second overflow, the now largely degassed solution is returned to the solution container and recirculated. The invention provides a compact structural form with a pressure-free recirculation system and simple maintenance of the electrode stack or individual electrodes.
