Apparatus for obtaining the anodic oxidation products of a solution of alkaline or alkaline-earth metal chlorides

The present invention relates to an apparatus for obtaining the anodic oxidation products of a chloride solution, wherein said apparatus comprises at least an electro-chemical cell that includes an anode and a cathode made of a material which is not soluble upon electrolysis. The electrode gap between the anode and the cathode is divided by a cylindrical diaphragm made of ceramic so as to obtain two electrode chambers, i.e. an anode chamber and a cathode chamber. This apparatus also comprises systems for supplying or discharging the solution to be treated in the chambers, wherein said systems are connected to solution circulation circuits located in said chambers. This apparatus further comprises a system for removing the gaseous products. The cell comprises an outer electrode (cathode) and an inner electrode (anode) which are coaxial and vertical as well as a diaphragm made of a ceramic containing a mixture of aluminium and zirconium oxides. The cell is further fitted with mounting and fixation lower and upper systems for the electrodes and the diaphragm, wherein said systems respectively comprise ducts for supplying and discharging the solution in and from the electrode chambers. The system for supplying a solution of an alkaline or alkaline-earth metal chloride is hydraulically connected to the lower part of the circulation circuit in the anode chamber.
