    In tube heat exchangers are in permeators (100) having hollow fiber membranes (116) suitable for fluid separations, the tubes or fibres are embedded in a tube sheet (120) and the tube sheet is positioned in a fluid tight relationship within a casing (102 by a cup seal (141). The cup seal comprises a polymeric ring which substantially surrounds and cooperates with a resilient member to provide both a pressure- actuated and self-actuated fluid tight seal. <IMAGE>

    1 The invention relates to membrane apparatuses and can be used for separating liquid mixtures of desalting and purification of aqueous solutions, for concentrating solutions in the chemical, food, microbial and other industries. A permeator is known, in which semi-permeable membranes are made in the form of hollow fibers fixed in tube sheets. Installed in a housing. A permeator is also known, between which body and tube sheets are installed gaskets for sealing the joint 2j. The disadvantage of these permeators is the leakage between the casing and the grilles when changing the dimensions of both the casing and the grilles resulting from temperature fluctuations, the influence of agents that cause swelling of construction materials, etc. Closest to the present invention, there is a permeator consisting of an elongated tubular body, having at least one open end and fittings for input and output of a separable solution, waterproof with a permeate outlet fitting, hermetically connected to the body, a longitudinal bundle of hollow parallel semi-permeable one end of which is hermetically sealed with a water-tight tube sheet as well as a sealing gasket in contact with the tube sheet h. However, a tight connection between the housing and the tube grid is provided by a gasket that does not guarantee reliable operation of the permeator when the tube grids are shifted relative to the housing. The purpose of the invention is to increase the reliability of the permeator with a relative shift of the tube sheet. This goal is achieved due to the fact that in the permeator, consisting of an elongated tubular body, having at least one open end and fittings for inlet and outlet of a separable solution, a waterproof cover with a permeate outlet fitting sealed to the body, a longitudinal beam 122 semi-permeable hollow parallel fibers, one end of which is hermetically sealed in a moisture-tight tube sheet, as well as a gasket in contact with the tube sheet, a gasket made in de U -shaped in cross-section of the polymer ring, which is located in the cavity of the resilient member. FIG. 1-5 shows variants of permeators with a different location of the gasket relative to the tube sheet and the housing; in fig. 6-8 are schematic diagrams of transverse sections of gaskets with various designs of elastic elements. The permeator contains a tubular body 1 made of metal or plastic. On one side of the housing there is a fitting 2 for introducing the solution to be separated and a flange 3 to which the end cap 4 is fixed. On Krishka 4 is located fitting 6 output permeate. On the other side of the housing there is a flange 7, a gasket 8 and a bolt 9 with a fitting 10 for the production of the solution to be separated. Inside the housing 1 is a bunch of 11 hollow semi-permeable fibers. Up to 1 million fibers can be in one bundle; the beam section profile repeats the cross section profile of the body. One end of the bundle 11 can be poured in the plug 12 or simply sealed by melting the ends of the hollow fibers. The second end of the beam 11 is fixed in the tube sheet 13, with each fiber constituting the beam extending through the open channel to the opposite side of the tube grid 13. The beam 11 near the tube grid 13 passes through the thickening 14 in the housing 1, in which the flow channels connecting a fitting 2 with an internal volume of the housing 1. A sealing gasket 15 serves to seal the tubular lattice in the housing. A gasket 15 is made under the gasket 15, which is located in different parts of the device in permeators of various design options. B. The embodiment shown in FIG. 1, slot 16 is provided on 3 of the inner surface of the expanded portion of body 1. On the front cover there is an annular protrusion 17 that presses the tube sheet 13 to the springs 18, which create the necessary effort to press the tube plate 13 to the crest 4. In the permeator shown in FIG. 2, the tube sheet 13 has an expanded part 19 and a narrow part 20. A sleeve 22 is placed at the end 21 of the expanded part 19, on the inner surface of which a socket 16 is placed. The sleeve 22 is attached to its flange 23, through which an additional gasket 24 takes place compression of the whole structure. The permeator of the embodiment shown in FIG. 3, has a two-part tube sheet. The end 22 of the expanded part of the tube sheet rests against the sleeve 22, which in this case is hermetically attached to the end cap 4, for example, by welding. The saddle 16 is also provided on the inner surface of the sleeve 22. For ease of installation of the sealing gasket 15, the sleeve 22 is provided with a removable ring 25, which is attached to the sleeve 22 by bolts 26. A narrow part of the tube sheet 13 can be provided with grooves 27 that do not reach the extended end 21 parts. FIG. 4 depicts a variant of the permeator, in which the sealing strip 10 is in contact with the end surface of the tube sheet 13 having also narrow and widened parts. Here, the seat 16 is formed on the end portion of the sleeve 22. The device is compressed by means of a flange 23, a sleeve 22 and springs 18. FIG. 5 shows a variant of the permeator, in which the socket 16 is made on the inner surface of the end cap 4, and the sealing gasket contacts the end of the tubular grille) 3. In all the above versions of the permeator, sealing gaskets can be used, shown in FIG. 6th. Each of them consists of an I) -shaped ring 28 in a cross-section of the research institute, in the cavity of which an elastic element 29 is located. The ring 28 may be made of a polymeric material, preferably of a fluorocarbon polymer. The elastic element 29: may be a helical wire spring (FIG. 6) or an I-shaped metal spring (FIG. 7 and 8). Preferably, the elastic element 29 is made of corrosion-resistant metal alloys, of stainless steel. Permeator works as follows. The separable solution is fed under working pressure to fitting 2, from which it spreads between the fibers of bundle 11 inside housing 1. Permeate penetrating through the walls of hollow fibers through the inner fibers of the fibers passes to the end of the bundle fixed in the tube sheet 13 and collects through the open ends of the fibers the space between the tube sheet 13 and the end cap 4 and the fitting 6 is led out of the permeator. The flow that does not pass through the membranes is removed from the permeator through fitting 10. A sealing gasket 15 is used to seal the tube sheet to prevent mixing of the permeate and stock solution. In those cases, the expansion or shrinkage of the tube grid occurs under the influence of working solutions, chemicals or temperature. body or end cap, which is fraught with depressurization of the apparatus and a decrease in the efficiency of its operation, the size fluctuations taking place at the same time take on a seal 15, in which the elastic element 29 can be compressed or stretched under the force acting on it. The main advantage of such a compacting is its automatic action on any external force. In permeators equipped with such seals, reciprocal movements of the tube sheet and the body will not cause depressurization of the appardt.
