Multipurpose electrolytic device (MPED) for forced or spontaneous electrolytic processes, with independent electrolytes

Multipurpose electrolytic device (MPED) for forced or spontaneous processes of electrowinning of metals, electrooxidation (EOXI) or electroreduction (ERED) of ionic species with independent electrolytes which allows the electrolytic transformation of ions in a controlled manner, wherein the device (MPED) is a tank of solid and monolithic structure, manufactured of non-electrically conductive strategic material based on polymers, acrylic material or cellular cement and of a rectangular geometric shape;

• wherein the device MPED comprises two end containing sides, one right and one left, and two contiguous perforated inner sides or walls joined by bolts with washers and nuts inserted into perforations arranged in register on each inner side;
• wherein the MPED further comprises two inner compartments, one cationic and the other one anionic, each formed by two lateral sides and one lower horizontal side adhered to said end containing sides and coincidentally overlapping when facing each other;
• wherein said two inner compartments are connected by means of a selective and unidirectional ion exchange membrane centrally disposed in between a window or perforation formed in each of the inner perforated sides or walls, the membrane being either a cationic ion exchange (CIEM) membrane or anionic ion exchange (AIEM) membrane, depending on the process, wherein a strategic solution (SS) is respectively injected into each inner compartment as catholyte or anolyte and strategic electrodes corresponding to a cathode and an anode are respectively submerged into the catholyte and anolyte;
• wherein each electrode is connected to a respective conductive bar;
• wherein in the lower part of each inner compartment there is located a solution distributing pressurized tank;
• wherein said solution distributing pressurized tank is connected by one of its ends to a solution inlet pipe and in the upper face of said solution distributing pressurized tank there is located a perforated solution distribution bar or plate;
• wherein the perforations of the distribution bar or plate have an inclination angle pointing toward the surface of the ionic exchange membranes;
• wherein the other end of the solution distributing pressurized tank is closed;
• wherein each of the inner compartments comprise therein a vertical side wall which is smaller in height than that of the lateral sides of the compartment, thus forming an overflow tank opposite the solution inlet pipe for discharging strategic solution (SS);
• wherein said overflow tank is connected to a solution outlet pipe;
• wherein the MPED incorporates a compartment lid or seal for controlling the pressure of the fluid contained therein as a strategic solution (SS), either as catholyte or anolyte, wherein said compartment lid or seal incorporates a gas conveying pipe.
