    A membrane separation apparatus of hollow fiber type which comprises a hollow fiber package body in a cylindrical shape comprising a core pipe or tube available as a passage for a fluid and a hollow fiber layer surrounding said core pipe or tube, said hollow fiber layer being formed by arranging hollow fibers having a selective permeability around and on the outer surface of said core pipe or tube, characterized in that (1) at least two perforated holes are provided on the wall of said core pipe or tube at the position near either one of the entrance or exit of said passage so as to flow the fluid into the hollow fiber layer therethrough and (2) the outer surface of the hollow fiber package body is covered by a film non-permeable to the fluid but leaving uncovered the edge portion of the outer surface opposite to the edge portion where said hole is present on the wall of said core pipe or tube.

    专利说明:

    The invention relates to the technique of separation of mixtures using semipermeable membranes made in the form of hollow fibers.
    The aim of the invention is to improve the quality of separation by reducing the effect of concentration polarization.
    FIG. 1 shows a membrane apparatus; figure 2 - the same, with permeable partitions; on fig.Z - the same, with a different arrangement of the inlet and outlet.
    The membrane apparatus consists of a bundle of 1 hollow fibers placed in a cylindrical body 2, and end caps 3 and 4. The bundle 1 contains a plurality of hollow fibers 5 arranged around the central tube 6 and fixed in end plugs 7 and 8 of resin. Outside, the beam 1 is covered with an impenetrable film 9 and a supporting sheath 10. In the central tube 6 near one of the end caps 8 there are several distribution openings 11 placed evenly around the circumference of the tube 6. On the opposite side, near the end cap 7, an annular gap 12 is made 9 and end cap 7.
    In the end cover 3, a passage 13 is formed to discharge permeate fibers penetrated through the walls. Between the end cap 3 and the end plug 7 a permeate collection chamber 14 is formed.
    The end cap 4 includes a fitting 15 for introducing the mixture to be separated and a channel 16 for withdrawing the concentrate. The central tube 6 is connected to the introductory fitting 15 by a sleeve 17. An annular space 18 is formed between the body 2 and the impermeable film 9; In one of the options in

    end plugs 7 and 8 are fixed permeable partition walls 19, made in the form of cylinders.
    The membrane unit operates as follows.
    The separable mixture is fed through the nozzle 15. Through the nozzle 17 it passes into the central tube 6 and through the holes 11 it is distributed radially between the hollow fibers. The mixture then moves longitudinally along the central tube and the hollow fibers 5 and close to the end plug 7 through the annular gap 12 into the annular space 18 formed by the impermeable film 9 and the housing 2. The permeate penetrating through the walls of the fibers 5 collects in the chamber and from the apparatus .. The remaining concentrate in the annular space 18 moves in the opposite direction and after 16 is also removed from the apparatus,
    In the embodiment shown in Fig. 2, in order to better distribute the flow of the mixture to be divided between the fibers, permeable partitions 19 are made of fabric, coarse nonwoven materials and other permeable materials,
    Fig. 3 shows an embodiment of the apparatus in which the distribution holes 11 are located at the end of the central tube 6 far from the point of entry of the mixture to be divided. The apparatus in this case also works.
    The advantages of the apparatus proposed are that the entire flow of the mixture to be divided is distributed among the hollow fibers only at one end of the bundle, and not along the entire length of the central tube. Due to this, the linear velocity of fluid flow along the fibers increases, which reduces the harmful effect of concentration polarization and, accordingly, increases
    machine performance and separation quality.
    Hollow fibers in the beam should be positioned at an angle to the axis of the apparatus, which should not exceed 60 °. In this case, solid particles that may be in the flow of the mixture to be separated do not get stuck between the fibers. This effect is most significant at an inclination angle of 45 ° and less.
    The size of the annular gap 12 should be no more than 20% of the length of the bundle of hollow fibers, optimally 0.4-5.0% of the length.
    The permeable guides 19 should be 20-300 mm long and 0.1-3-3 mm thick and installed with a gap of 1-20 mm.
    Distribution holes 11 in an amount of at least 2 are advantageously made at a distance from the end stoppers of 0.2-30% of the thickness of these end stoppers. The diameter of these holes may be 5-50% of the inner diameter of the central tube.
    The implementation of these recommendations will improve the efficiency of the membrane apparatus.
