FLAT-CHAMBER ELECTROBAROMEMBRANE EQUIPMENT Russian patent published in 2017 - IPC B01D61/42 B01D61/46 

FIELD: electricity.

SUBSTANCE: lat-chamber electrobaromembrane equipment is comprised of two flange-mountings, input and output channels of a shareable solute and a permeate diversion, flow of direct current input device, body structure interchangeable dielectric bousings that are concatenated in a male-female joint way, vent for electric conductor supply. It is distinctive in that the interchangeable dielectric bousings of a body structure with "male" and "female" have the square-topped overflow window openings where the drain screens, monopolar diffusers of electrode- cathode or electrode-anode, porous templates of a map paper, cathode and anode membranes are in stages positioned at a full-length and across the entire width of the square-topped overflow window openings in the form of the continuous length of fabric on the top and on the bottom on one side of the body structure interchangeable dielectric bousing with "male" and "female" and up to the other side, respectively to the exterior layings perimeter with exception of those porous templates of a map paper, cathode and anode membranes places where the 2 mm thick slab wafer-insertions are placed that bind the monopolar diffusers of electrode-cathode and electrode-anode. Along the inside perimeter of the layings there are square-topped umbilicate spaces with the size of 0.5 mm of their thickness and across the width of one third of their part, in what connection, in those square-topped umbilicate spaces across the whole inside perimeter of the layings there are mesh- vortex-generator ends that correspond to the intertangled with the 90 grad. angle inplane set of the cation-exchange and anion-exchange membranes lots. The intermembrane channel is accomplished in space of square-topped overflow window opening of interchangeable dielectric bousing of a body structure with "male" and "female". This channel is polymer filled at full width and height under the laying and from laying to laying on the one side of interchangeable dielectric bousing of a body structure with "male" and "female" up to the other side. The intermembrane channel is also formed therein where the mesh-vortex-generator is located. The dielectric body flange internal surfaces are equipped with sequentially arranged against each other drain screens, monopolar diffusers, electrode-cathode, porous templates of a map paper, cathode membranes respectively. There are dual-sided vents for electric conductor supply in the interchangeable dielectric bousings of a body structure with "male" and "female". These vents are polymeric compound filled from the negative and positive terminals of the equipment for the flow of direct current supply and are linked to the drain screens. On the inside of the dielectric body flange, there are a vent for the electric conductor supply from the negative terminal of the equipment for the flow of direct current supply to the drain screen and a channel for the cathode permeate diversion. This channel has the dielectric mesh in the entire area. These vent and channel are located at the same places as in the interchangeable dielectric bousings of a body structure with "male" and "female" where the channels for the cathode and anode permeate diversion are situated and vents for the electric conductor supply, depending on the electrodes "minus" or "plus" connection scheme.

EFFECT: cathode and anode permeate differential exudation capability improvement, quality and solute partitioning efficiency upgrading, resistance to flow in the equipment decrease, space extension of cathode and anode membranes per equipment unit volume, prevention of the mesh-vortex-generator bias from the working surface part.
