UNIT FOR THE NITROGEN FROM AIR SEPARATION USING THE HOLLOW FIBER MEMBRANES Russian patent published in 2018 - IPC B01D63/02 B01D53/22 

FIELD: instrument making.

SUBSTANCE: invention relates to the hollow fiber membrane for the nitrogen selective separation from the compressed air stream. Unit for the nitrogen from air separation using the hollow fiber membranes, comprising the hollow fiber membranes bundle for the nitrogen separation from compressed air stream directed to the hollow fiber membranes bundle first inlet end, at that, the hollow fiber membranes bundle is located inside the outer casing, made with the compressed air stream at least one inlet, at least one second intermediate outlet for the filtrate gases output and the third outlet for the separated nitrogen output, used for painting by means of the pneumatic systems, wherein this opening is located at the opposite relative to the inlet opening casing end, wherein the said fibers bundle forms the free space between the inlet opening and the bundle first end, according to the invention, comprises deflector, communicating with the inlet opening and intended for the compressed air flow deflection within the said space along the flow paths, not directed straight to the said fibers bundle first input end.

EFFECT: technical result is decrease in the membrane fibers wear and simplification of the membrane module construction.
