ELECTRO-MEMBRANE APPARATUS OF PLANAR CHAMBER TYPE WITH COOLING OF SEPARATED SOLUTION Russian patent published in 2018 - IPC B01D61/42 B01D61/46 

FIELD: electrical engineering.

SUBSTANCE: invention should be attributed to devices that are designed for electrohyperfiltration and electron-nanofiltration separation, concentration and purification of process solutions. Electrobaromembrane apparatus of flat chamber type with cooling of the separated solution, including chambers of separation with the channels of input and output of the separated solution and channels for withdrawing the near-cathode or pre-anode permeate, the cooling chamber, the hole for the hairpins, devices for supplying a direct electric current to the chambers of the apparatus, near-cathode or pre-anode membranes, overflow apertures, gaskets, grid-electrodes, plate-electrodes, ion-exchange membranes, differs in that the cooling chambers in it are located between the separation chambers separated from them by 1.5 mm thick titanium sheets that are covered with a layer of a ceramic polymeric dielectrically conductive dielectric silicone mass, the cooling water inlet and outlet channels are arranged two in each large flange symmetrically to the horizontal axis of the apparatus at a distance of 100–110 mm from it and are displaced 5 to 6 mm to the left of the middle of the cooling chamber, right and left grid-electrodes are configured in the form of ten rods with a diameter of 1.5–2 mm, evenly spaced from each other by a distance of 20 mm, bent in the form of two turns of a sinusoid, but the ends of the bars are not bent to the end and have a straight cylindrical portion and are arranged vertically with respect to the upper and lower boundaries of the separation chambers, as well as soldered each in six places to six straight rods of the same diameter, perpendicular to the curved, two of these straight rods have an elongation on the right or left side, depending on whether the right or left is an electrode grid, with which each electrode grid is attached in two places in an unchanged position to the corresponding large and small flanges of the housing by performing in these flanges and paronite cushions the chambers of the separation of the bores of the same diameter as the elements of the nets-electrodes protruding beyond the body of the apparatus, as well as filling the sealing composition with external grooves with increased diameter.

EFFECT: improved cooling of the separated solution; reduced the temperature load on the membrane; increased degree of turbulence of the separated solution.
