Abstract: FIELD: electrical engineering.SUBSTANCE: invention relates to design of tubular-type membrane apparatuses. Tubular type electric baromembrane device consists of: cylindrical housing with mating and end flanges, unipolar electrodes – anodes and cathodes, collectors of anode and cathode permeate, channels of anode and cathode permeate, through and non-through holes for tubes with anode and cathode membranes located outside, respectively, sealing of tube grids through sealing gaskets and gaskets with pressure grids and cylindrical housing with mating flanges respectively is performed by means of tightening end flanges and mating flanges on cylindrical housing by means of bolts, washers and nuts, which are located on end flanges in their section at angles from horizontal axis 0, π/3, 2π/3, π, 4π/3 and 5π/3, respectively, located from edge of end flanges at distance of 15 mm, terminals of device for supply of electric current, nozzles of input of initial solution and withdrawal of retentate, nozzles for output of pre-anode and cathode permeate, gaskets, probes of right and left cylindrical, hold-down grids, wherein between tube plates and pressure grids there are monopolar electrodes – anode and cathode, respectively, in which there are through holes for cooling tubes, as well as in pressure grids, cooling tubes are sealed through annular gaskets, terminals of device for supply of electric current, touch monopolar electrodes of round shape – anodes and cathodes respectively, which are located in corresponding to them round seating areas in clamping grates on thread at location from horizontal axis in section of device at an angle π/2, right and left cylindrical probes have a welded connection at the base with unipolar electrodes – anodes and cathodes and arranged in staggered order in the apparatus section, as well as tubes with anode and cathode membranes located outside, respectively, with the exception of those places, where there are cooling tubes, which are from horizontal axis in section of apparatus, limited by sector from 0 to π/2, are located in the first, third and fifth row and column respectively on: – third, – first, third, fifth, – third place respectively, as well as in other sectors from π/2 to π, from π up to 3π/2 and from 3π/2 to 2π during mirror display of sector from 0 to π/2 along vertical and horizontal axes in apparatus section, end flanges are made in the form of flat round covers, from the outer side of which in the centre there are through holes with thread, into which the coolant inlet and outlet connecting pipes are screwed, between end flanges and pressure grids there is a limiting gasket, which creates a gap for distributing and collecting channels of cooling liquid, respectively, channels of anode and cathode permeate, which are formed between tube plates and unipolar electrodes – anode and cathode respectively, and tubes with out-of-the-ate and near-cathode membranes located on the outside are larger in diameter, respectively.EFFECT: increased area of membranes for separation of solutions, implementation of cooling process of initial (separated) solution and permeate, reduction of hydraulic resistance in chamber of separated solution.1 cl, 6 dwg
