ELEKTRO-BAROMEMBRANE APPARATUS WITH FLAT COOLERS Russian patent published in 2017 - IPC B01D61/42 B01D61/08 

FIELD: technological processes.

SUBSTANCE: electrically-baffle apparatus with flat cooling chambers is provided in which the first and the last flanges of the apparatus body are formed with a protrusion and a depression respectively along a flat sealing surface in which monopolar porous electrodes are installed and membranes are laid, and between the first and last flanges there are unified intermediate flanges of the housing with channels For the circulation of the solution and the gasket, in which there are also openings for circulation of the solution. Between the first and second, third and fourth, fifth and sixth, seventh and eighth intermediate flanges of the casing are located on both sides of the rubber gaskets dielectric plates, which in pairs form a cooling chamber. On the respective intermediate flanges of the housing are located the connections for the input and output of the cooling agent, and on the first and last flanges of the housing, there are channels and connections for the input and output of the separated solution. Solution separation chambers and cathode and anode permeate cooling chambers alternate in the unit. Housing chamber has cathode and anode permeate discharge unions depending on via which unipolar porous electrode and membrane flows the permeate. To prevent leakage of the initial and concentrated solution, as well as to provide the necessary path of circulation of the solution in the apparatus, on the outer sealing surface of the flanges of the housing there are unified external paronit gaskets whose internal cut-out size, in order to simplify the alignment of cylindrical flange channels and gasket holes during assembly, The dimensions of the flange of the housing flanges. To ensure the circulation of the divided solution in the intermembrane space, rubber gaskets are installed with holes that are aligned with the cylindrical channels of the intermediate flanges of the housing. Ion-exchange spacers are arranged nearby membrane surface and consisting of ion-exchange substance granules and mesh. The supply of electric current to the monopolar porous electrodes is carried out from a DC power source through electrical wires and openings located in the intermediate flanges of the housing and on the last flange of the housing and filled with the sealing composition. To ensure the strength and rigidity of the structure of the electro-barrier apparatus with flat cooling chambers, metal plates are installed on the outer surface of the first and last flanges of the housing.

EFFECT: increase in the effective area of the membranes, simplification of manufacturing and simplification of assembly due to Changes in the design of the device.
