    In a permeator containing hollow fiber membranes, a resilient means 126 cooperates between a tubular shell 102 containing the hollow fiber membranes 116 and at least one tube sheet 118 through which bores of the hollow fiber membranes communicate wherein a force directing the tube sheet longitudinally outward from the shell is provided. An end closure cap 128 is adapted to be removably fastened to the end of the shell proximate to the tube sheet. A first sealing means 130 is positioned between the end closure cap and the shell to provide an essentially fluid-tight relationship, and a second sealing means 134 is positioned between the end closure cap and the tube sheet wherein the resilient means provides a sufficient force on the tube sheet that the second sealing means provides an essentially fluid-tight seal. <IMAGE>

    one
    The invention relates to chemical engineering, and more specifically to devices for separating liquid and gas mixtures using semipermeable membranes, and can be used in any industry where such separation is necessary.
    One of the most promising types of devices for membrane separation of a permeator mixture is apparatus with semipermeable membranes in the form of a hollow fiber. Known designs such permeator containing a bundle of hollow semi-permeable fibers, placed in a tubular body. The ends of the bundle of hollow fibers are fixed in tube lattices, usually made of epoxy resins. To seal the apparatus, O-rings are used, placed between the side surface of the tube sheet and the inner surface of the housing. On both sides of the body there are end caps, which form the ka-. measures - collecting component passing through the membrane - permeate 1 and 2.
    A disadvantage of such permeators is the difficulty of assembly and disassembly due to the indicated arrangement of O-seal seals. In addition, careful sealing of the inner surface of the housing and the lateral surface of the tube sheets is necessary to ensure reliable sealing.
    Closest to the proposed one is the Permeator, which contains a tubular body with inlets and outlets for a separable mixture, an end cap with a permeate outlet fitting, a sealing gasket located between the body and the end cap, a bundle of hollow semi-permeable fibers fixed at the end of the tube sheet, the diameter of which is equal to the diameter of the bundle of hollow fibers, as well as a sealing gasket located between the end surface of the tube sheet and around the open ends of the hollow fibers 3.
    A disadvantage of the known permeator is the Violation of its tightness due to a significant difference in the degree of expansion of the tube sheet and the housing when the device is heated, under the action of swelling agents contained in the treated mixture.
    The purpose of the invention is to preserve the sealing of the permeator while changing the dimensions of any of its nodes.
    This goal is achieved due to the fact that
    permeator containing tubular Kopav ;. with fittings for input and output section of the mixture, end cap with permeate outlet fitting, sealing gasket located between the body and the end
    a lid, a bundle of hollow semi-permeable fibers, fixed end in a tube sheet whose diameter exceeds the diameter of the bundle of hollow fibers, as well as a sealing gasket located between the end surface of the tube set and a lid around the open ends of the hollow fibers, and the tube grid it is provided with an elastic element for gujati tube sheet to the end cap in contact with the housing and the tube
    lattice.
    The tube sheet can be located in the housing, and the elastic element can be located between the inner surface of the housing and the tube sheet.
    The tube sheet can be located on the housing side, and the resilient element can be located between the end surface of the body and the tube sheet.
    FIG. 1 given the location of the elastic
    element at the open end of the housing around the coarse grille placed in the housing, a longitudinal section; in fig. 2 - the location of the elastic element between the end surface of the body and the pipe lattice placed outside the body, longitudinal
    incision; FIG. 3 and 4 - the location of the elastic element and the tube sheet inside the body, a longitudinal section.
    The permeator contains a tubular body 1. It can be made of any convenient waterproof material - metal, plastic, etc. The housing may have any convenient profile in cross section, however, a circular cross section is preferred. From one end of the housing is placed; front flange 2,
    necessary to press the end cover: 3, from the other end - the rear flange 4 for fastening the back cover 5 sealed to the housing of the rear cover 5, sealed with a gasket 6. On
    The housing 1 has a fitting 7 for introducing the initial mixture and a fitting 8 for withdrawing it. A plurality of fittings 7 may be located on the housing 1 to provide a better distribution of the mixture to be separated in the housing.
    Inside the housing 1, a bundle 9 en composed of a set of hollow semi-permeable fibers (depending on the ratio of fiber and body diameters from 10,000 to 1 million) is en. Hollow fibers can be made of any synthetic or natural material, depending on the conditions of the separation process. The outer diameter of the hollow fiber can vary from 20 to 1000 µm, and the wall thickness from 5 to 3000 µm. The bundled fibers can be straight or spirally twisted.
    One end of the beam 9 is fixed in the tube sheet 10. Each hollow fiber passes through the tube sheet 10 and has an open channel on the end surface of the tube sheet. The other end of the beam can be fixed in the plug 11 (Fig. 1), can be turned up and fixed in the tube sheet 10, so that the beam becomes U-shaped, can be fixed in the second, symmetrical first tube tube. The tube rack 10 and the plug 11 can be made in any convenient way, for example, by casting a bonding material or by impregnating the ends of the hollow fibers with a bonding material.
    As shown in FIG. 1, the tube sheet 10 in this embodiment is placed in the pipe 12 and is fastened to it with a plurality of screws 13. A flange element 14 is attached to the pipe 12. Between the element 14 and the flange 2 of the housing 1 there are a number of installation pins 15 with elastic elements 16 made in the form springs. The pins 15 are placed in the drilling 17 made in the flange 2 of the housing 1. A sealing gasket 18 is placed between the end cap 3 and the flange 2. In the end cap 3 there is an annular groove 19 in which a sealing seal 20 is placed around the open ends of the hollow fibers in a pipe grate 10. The diameter of the tube sheet 10 is smaller than the internal diameter of the housing 1. As a result, the pipe lattice can move along the axis of the housing. The spring 16 presses the tube sheet 10 through the flange element 14 to the end cap 3, on which is placed the fitting 20 for the output of permeate.
    FIG. 2 shows a variant of the permeator, in which the tube grid 10 is placed
    outside the housing 1, in the cavity of the end cover 3 with the possibility of movement along the permeator axis. The elastic element 16 is made in the form of a wavy spring and is placed between the end of the housing 1 and the tube sheet 10.
    FIG. Figure 3 shows a variant of the permeator, in which the housing 1 is designed as a cylindrical tube extending into the inside of the flange 2. To fix the relative position
    0 of the housing 1 and the flange 2, a sleeve 22 is inserted with holes 23 for the passage of the mixture to be divided and its distribution between the fibers of the bundle 9. An elastic element 16 in the form of a wavy spring is placed between the sleeve 22 and the tube sheet 10. The latter can
    5 move along the axis of the permeator in the flange 2. Between the end cap 3 and the flange 2 is placed an intermediate element 24 provided with an additional gasket 25. In FIG. 4 shows a variant of the permeator Q in which the beam 9 passes through a distribution element 26 having channels (not shown) and serving as a support for an elastic element. The latter is made in the form of two springs 27 and 28, separated by washer 29. By selecting various springs and washers, one can obtain the required intermediate distances and elasticity of the whole element. The sealing seal is also made of a composite and contains an intermediate ring 30, on two end sides of which O-o different gaskets 31 and 32 are placed in the grooves. The choice of the width of the intermediate ring 30 provides the required compressive force of the springs 27 and 28.
    Permeator in any case works as follows.
    The split mixture through the nozzle 7 is inserted into the body I, where it is distributed between the hollow fibers of the beam 9 and, having washed them, passes along the entire beam and is withdrawn from the permeator through the nozzle 8. The penetrating component, the permeate, passes
    0 into the hollow fibers and through the capillaries is led out of the beam through the open ends of the hollow fibers fixed in the tube sheet 10, and then out of the permeator through the nozzle 21.
     The advantage of the proposed permeators is that the replacement of the hollow bundle of fibers is greatly facilitated, the need for careful treatment of the inner surface of the housing is eliminated, changes in the dimensions of the tube sheet, sealing the seal that can occur when the permeator is heated or the swelling agents of the separable mixture are easily compensated .
