MEMBRANE APPARATUS WITH THE TOROIDAL VORTEX GENERATORS Russian patent published in 2006 - IPC B01D63/06 

FIELD: food industry; pharmaceutical industry; microbiological industry; agricultural industry; devices and methods of reversed osmose and ultrafiltration.

SUBSTANCE: the invention is pertaining to the field of separation, concentration and a desalting of various solutions and may be used in food industry, pharmaceutical industry, microbiological industry and also agricultural industry. The membrane apparatus includes: a tubular membrane unit, branch pipes for an initial solution feeding and withdrawal of a filtrate and a concentrate; and creating turbulence devices. On the surface of the semipermeable membrane there are the stationary mounted gear racks. In the tubular membrane module coaxially to the surface of the semipermeable membrane there a pusher is located, on the surface of which there are the stationary mounted support shaped washers equidistantly spaced from each other, to which along the circumference of the pusher are welded gear racks. At that the symmetry axes of the gear racks located on the surface of the semipermeable membrane coincide with the symmetry axes of the pusher gear racks. Between the gear racks arranged on the surface of the semipermeable membrane and the gear racks of the pusher there are the toroidally-shaped vortex generators with the closed gear-type belts interacting with the gear racks, the quantity and location of which are chosen so, that to ensure the correct geometrical shape of the toroidally-shaped vortex generators. On an outer surface of each toroidally-shaped vortex generator there are the blades mounted between the closed gear-type belts. The technical result of the invention is an increased productivity of the membrane apparatus due to improvement of the hydrodynamic impact on the separated flow.

EFFECT: the invention ensures an increased productivity of the membrane apparatus due to improvement of the hydrodynamic impact on the separated flow.
