FIELD: separation.
SUBSTANCE: invention relates to cartridges and modules for separation of mixtures of fluids. Cartridge for separation of a mixture of fluids, preferably a mixture of gases, comprising: a pipe for collecting permeate, consisting of one or more sections and having a front end and a rear end, a plurality of hollow fibre membranes located around the tube for collecting permeate and having front ends located on the side front end of the permeate collector tube, and rear ends located on the side of rear end of pipe for collection of permeate, first tube screen located at front ends of hollow fibres and front end of pipe for collection of permeate, and a second tube plate arranged at the rear ends of the hollow fibres and the rear end of the permeate collecting tube, a barrier which is impermeable to the mixture of separable fluids and a surrounding arrangement consisting of a tube for collecting permeate and hollow fibre membranes, in the region between the first tube sheet and a second tube grid, a front end cover located over the first tube plate, and optionally a rear end cap, which if present is located above the second tube sheet, wherein the permeate collection tube or all of its sections are made in the region between the first tube plate tube grid and second tube grid impermeable for mixture of separated fluid media, impermeable barrier in section corresponding to first one-third, preferably first quarter, measured along longitudinal axis of cartridge distance between first tube screen and second tube grid, more preferably on the distance measured from the longitudinal axis of cartridge from 0 to 10 cm from the inner end surface of the first tube plate, most preferably at distance of 2 to 4 cm from the inner end surface of the first tube plate, measured along the longitudinal axis of the cartridge, is configured such that it has one or more openings or slots for the fluid to enter the space between the impermeable barrier and the permeate collecting tube, rear ends of hollow fibres are embedded in second tube plate, wherein hollow fibre cores at their rear ends are closed, leading ends of hollow fibres are embedded in first tube grid, wherein hollow fibre cores at their front ends are open, front end cover is made and located above first tube grid so that in front end cover is formed cavity located between outer end surface of first tube plate, where hollow fibre cores are permeate, and the inner surface of the front end cap, in the permeate collection tube or in the permeate collection pipe section, there are permeate outlet openings located in the cavity of the front end cover and communicating the cavity of the front end cover and the inner space of the permeate collection tube, there is at least one retentate exit opening made in the impermeable barrier in its section corresponding to the last quarter of the distance between the first tube sheet and the second tube grid or embedded into the second tube sheet.
EFFECT: technical result is higher efficiency of separation.
