FLUID CLEANING MEMBRANE MODULE Russian patent published in 2015 - IPC B01D63/00 B82B1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to power engineering, transport, petrochemical and other industries. Membrane module comprises housing (4), filtration elements arranged therein and mounted on tube plate (15) with the help of unions (18), hydraulic accumulator (3), feed branch pipe (11), lateral (1) and bottom (10) discharge branch pipes, perforated distributing grid (14) communicated with said branch pipes (1, 10, 11), and valves (5, 6, 7). Filtration elements consist of cylindrical porous substrate (12) and nanostructured membrane (8) constricted by bottom (9) and top (2) adapters from below and above. One filter element is arranged at the centre of housing (4) while other filter elements are arranged in one row to make a hexagonal package. Guide plate (19) is secured above tube plate (15) and has holes for passage of unions (18) to make therewith a flat slit channel. Outer side surface of unions (18) is arranged to contact with inner side surface of guide plate (19) holes. Lower ends of filtration elements are embedded into appropriate orifices of distributing grid (14) to form annular channels there between. Separation shell (13) is arranged inside housing (4), along its inner side surface, to make a circular channel there between. Top part of separation shell (13) is connected with peripheral section of guide plate (19). Guide plate (19) cannot get beyond separation shell (13) in radial direction.

EFFECT: higher efficiency of cleaning.
