ELECTROBAROMEMBRANE APPARATUS OF ROLL TYPE Russian patent published in 2023 - IPC B01D61/46 

FIELD: roll-type membrane apparatuses.

SUBSTANCE: invention relates to designs of roll-type membrane apparatuses. Roll-type electrobaromembrane apparatus, in which inside the perforated tube there is a hermetically installed transverse partition dividing the perforated tube into two equal parts, on the outer surface of which there are four sets of through perforations in the form of elliptical grooves, along the perimeter of which there are large semi-ellipses, made at a distance of 5 mm from each other, and on the inner surface there are four semi-elliptical grooves, passing along the entire length of the generatrices with the exception of the section of the transverse partition and distributed from the horizontal axis at angles π/4, 3π/4, (-π/4), (-3π/4), the holes in the fixing gasket are made in the form of two crescents with rectangular edges, on the inner surface of the inner tube there are four semi-elliptical grooves and two small semi-elliptical grooves, running along the entire length of the generatrices with the exception of the section of the transverse partition and distributed from the horizontal axis at angles π/4, 3π/4, (-π/4), (-3π/4) and π/2, (-π/2), respectively, in a polymeric perforated partition, along with elliptical holes, there are through holes alternating with them, on a film having notches deepened into half of its thickness, in the form of parallelograms, there are also notches in the form of a sinusoid of the same depth; the body of the device and the cover are sealed through sealing and sealing gaskets with the help of a mating clamping flange using bolts, nuts and washers evenly spaced along the contour of the flange connection, on both sides of the rolled element on the outer surface of the perforated tube there are bushings located between the antibody grating and the cover .

EFFECT: reduction of hydraulic resistance in the channel for removal of retentate and near-anode, near-cathode permeate, increase in productivity and quality of solution separation, increase in the area of near-cathode, near-anode membranes for separation of solutions, increase in the area of the cooling surface and degree of cooling of near-anode, near-anode permeate, reduction of the effect of concentration polarization.
