ELECTRO-BAROMEMBRANE APPARATUS OF FLAT-CHAMBER TYPE Russian patent published in 2023 - IPC B01D61/42 B01D61/14 

FIELD: solution treatment.

SUBSTANCE: separation, concentration and purification of solutions by methods of electro-microfiltration, electro-ultrafiltration, electro-nanofiltration, electro-osmofiltration, used in chemical, engineering, food industry, and the agricultural sector. An electro-baromembrane apparatus of a flat-chamber type consists of dielectric flanges of the body, metal plates, gaskets, negative and positive terminals of the device for supplying direct electric current, fittings for draining cathode and anode permeate, bolts, washers and nuts, fittings for inlet and outlet of the separated solution, dielectric mesh, flanged drainage mesh, overflow window, polymer compound, double-sided openings for supplying electrical wires, channels for draining cathode and anode permeate, polymer composition, channels for inlet and outlet of the solution to be separated, alternating dielectric chambers of the body with a “ledge” and a “pocket”, made with a cavity in the form of a small separation chamber in the form of a rectangular parallelepiped, small cathode and anode membranes, under which there is a recess of 1 mm on the sealing surface of the dielectric chambers of the body with a “ledge” and a “pocket”, for installing a small rectangular linings at the place of installation of the drainage grid from its two opposite ends along a flat surface, monopolar-porous plates are installed in series - an electrode-cathode and a small electrode-cathode, monopolar-porous plates - an electrode-anode and a small electrode-anode, respectively, a porous cathode Whatman substrate and small porous anode Whatman substrate, porous anode Whatman substrate and small porous anode Whatman substrate, respectively, cathode membrane and small cathode membrane, anode membrane and small anode membrane, respectively, on the dielectric chambers of the body with a “ledge” and with “pocket” there are chamber fittings installed on the front and rear walls for input of the initial solution and output of the anode and cathode retentate, respectively, which are located at a distance of 30 mm and 70 mm and 50 mm and 90 mm, respectively, from the base of the apparatus along the central vertical axis of the housing chambers with a “ledge” and with “pocket”, respectively, the turbulence ring mesh is a set of cuts of cation-exchange and anion-exchange membranes intertwined at an angle of ninety degrees in one plane, characterized in that a cooling radiator is installed in the centre of each small separation chamber, which is a curved tube in four places at an angle of one hundred and eighty degrees and at the points of connection with the chamber fittings for the input and output of the coolant at an angle of ninety degrees, located in the same plane.

EFFECT: increase in productivity and quality of solution separation, turbulence, cooling of the separated solution and reduction of the effect of concentration polarization in small separation chambers.
