ELECTRO-BAROMEMBRANE FLAT-CHAMBER APPARATUS Russian patent published in 2017 - IPC B01D61/42 B01D61/14 

FIELD: technological processes.

SUBSTANCE: electro-baromembrane apparatus of planar chamber type consists of two flanges and chambers of the casing with channels for input and output of the separated solution and channels for tapping the cathode and pre-anode permeate, holes for studs, a device for supplying a direct electric current to the chambers of the apparatus, cathodic and pre-anode membranes, gear holes, studs, gaskets, characterized in that the apparatus between the chambers of the housing in the upper and lower parts of the space formed by the adjacent chambers of the shell or the flange of the body and the camera housing is shaped tubes forming flow channels and output of cooling water for separating the sleeve of the working solution and coolant streams soldered centrally in the tube forming the supply and withdrawal of cooling water channels, six cooling tubes in each intermembrane space, interconnecting the channels described above, uniformly distributed across their width, covered with ion exchange membranes and twisted around its axis into a 12 mm diameter spiral, as well as amphoteric ion exchange resin granules in a form resembling a hyperboloid of one sheet, but with this upper and lower surfaces of the granules are convex, which are located on the turns of two adjacent cooling tubes turned to each other, through a step of 40 mm.

EFFECT: simultaneous uniform cooling of all separation chambers, increase in migration rate of cations and anions, increasing the turbulence of solution flow in the separation chamber.
