Definitions

  • the present invention relates to the design of plate type heat exchangers. These are generally distinguished from tubular exchangers by the fact that the fluids in a heat exchange situation circulate longitudinally on either side of plates arranged contiguously parallel to one another.
  • exchangers of this type include a bundle of parallel planar plates which are generally made of thin sheets made of stainless steel, provided with corrugations by which they are in contact with one another and by which they organize the circulation of fluids longitudinally from one end to the other of the exchanger (generally against the current one another), creating turbulence favorable to the heat exchanges that take place between the fluids through each plate.
  • the plates are welded together by means of tongues or frames forming spacers which maintain the spacing between two successive plates.
  • the stack of plates is framed by two relatively thick sheets, which transfer the weight of the beam onto a support.
  • the thick and mechanically resistant sheets which frame the bundle of heat exchange plates serve to support the assembly in a chamber for resistance to fluid pressure or ferrule, to which they are rigidly connected in the middle part of the exchanger, by lateral hooking plates.
  • lateral hooking plates Such an embodiment is for example described in document FR-A-2288287.
  • the invention proposes a plate exchanger corresponding to a new method of mounting the bundle in its enclosure which responds better than previous plate exchangers to the different needs of the practice, in particular in terms of manufacturing convenience, in costs and operational safety.
  • a plate type exchanger comprising a bundle of heat exchange plates between fluids circulating between them which is disposed inside a pressure resistance enclosure, characterized in that it comprises means rigid suspension of said bundle to said enclosure at at least a first collector circuit comprising a first connection box at the upper end of the bundle and guiding a first of said fluids between this end and the outside of the enclosure.
  • the beam is now suspended according to the invention at the upper collector of the exchanger, which considerably limits the thickness of the sheets framing the beam, since they no longer have to take up suspension of the assembly. This also prevents the appearance of forces tending to spread these sheets in the lower part of the beam.
  • said first collector circuit comprises a conduit constituting the suspension means by the fact that it is in rigid connection with said connection box to suspend the latter from an upper cap closing the pregnant.
  • said suspension means comprise at least a first rigid connection plate of the first connection box with a ferrule limiting the enclosure around the beam.
  • connection box is made of thicker sheets than the plates constituting the bundle for use in the suspension of it.
  • the fluid collecting circuits as defined above are designed and dimensioned as a function of the properties of the fluids which they must convey.
  • said collector circuits are intended to receive respectively for the internal collector a fluid to be extracted from the exchanger at a relatively low pressure, and said external collector to receive a fluid at relatively high pressure close to the pressure of this fluid filling the enclosure when it enters the exchanger.
  • they are advantageously intended to respectively receive fluids of neighboring temperatures as follows from the efficiency characteristics of the device.
  • the first fluid is the fluid at relatively low pressure and the second fluid is the fluid at relatively high pressure.
  • the external and internal conduits each in at least two tubular sections welded end to end for the first embodiment or by means of an expansion bellows for the second preferred embodiment, an outer section adjoining the enclosure being made of the same material as the latter and an inner section adjoining the bundle being made of the same material as the latter.
  • the internal section of the external conduit is preferably constituted, for at least part of its length, by two semi-cylindrical walls which are welded together on generators opposite to the manufacture of the exchanger, after the internal conduit is butted .
  • the pressure conditions prevailing on either side of the walls of each of the collector circuits advantageously lead to mechanically suspending the beam by the internal collector circuit, the walls of which are relatively thick, while the construction of the external collector circuit uses relatively thin walls having a sealing function and not a mechanical suspension.
  • the fluid supply and extraction manifold circuits can be produced in any way in themselves conventional.
  • the exchanger according to the invention furthermore comprises means for centering the heat exchange bundle with respect to a cylindrical shell limiting the outer enclosure, which are further dimensioned to be able to support the bundle when it is not operating. in horizontal longitudinal position.
  • the present invention has appreciable advantages in the manufacture of plate heat exchangers and in the safety of their operation.
  • this therefore succeeds in eliminating the use of thick sheets of supports in the sides of the bundle which can constitute, in particular in the event of thermal shock, a thermal bridge between hot and cold parts; to remove any shear stress in the weld wall generally connecting the plates together; to remove any constraint linked to the weight of the beam in heterogeneous beam / enclosure link welds, the materials of which are generally different; and not to interfere with the expansion of the bundle during the operation of the exchanger.
  • the exchanger of the invention essentially comprises a bundle 1 of rectangular plates 2 for heat exchange between two fluids which pass longitudinally through the bundle, and an external enclosure 3, resistant to the pressure of the fluids, which encloses the bundle.
  • the exchanger is intended to operate in a vertical longitudinal position, the fluid inlets and outlets if killing at the two longitudinally opposite ends of the exchanger, at the top and bottom of the outer enclosure. However, it is intended that it can be easily transported in a horizontal position.
  • a first of these fluids is the charge; consisting of napthta, and hydrogen it represents the relatively cold fluid which must be preheated by the effluent in the exchanger.
  • the second is formed by the relatively hot effluent. It also happens that the charge of naphtha reaches the exchanger under a higher pressure than the effluent; this is why it enters, in the lower part of the exchanger, directly into the enclosure 3, which it fills, before crossing the beam.
  • the enclosure, or grille 3 is essentially limited by a cylindrical shell 10, enveloping over its entire length the bundle 1, and by two semi-spherical caps 4 and 5 which close the shell at the top and bottom of the exchanger. Taking into account the individual dimensions of the plates 2 and their number, the parallelepipedic beam 1 is contained axially in the shell 3. The collecting, supply and extraction circuits guide the two fluids between the beam and the exterior of the 'enclosure cross the grille 3 as will be described later.
  • the figures also show a tube 8 which comprises the lower cap 5 for introducing into the enclosure a recycling gas, and a manhole 9 closed by a plate 40, which serves to penetrate into the enclosure for mounting the elements. internal parts of the exchanger and its maintenance.
  • the production of the actual heat exchange bundle is in accordance with that which has been described in FR-A-2 638 226, to which reference will be made in particular as regards the production of the plates 2, as well as that of the orifices for the inputs and outputs of fluids at the ends of the bundle.
  • the plates 2 appear by their edge in FIG. 2, on a scale which does not allow it to be seen how they rest on each other by undulations which simultaneously have the role of providing passages between plates guiding the fluids towards the beam inlet or outlet manifolds.
  • These plates are manufactured with their corrugations by explosion forming of thin sheets of stainless metal. They are stacked together to form the bundle, with the interposition of metal tabs welded on their edges as spacers closing the passages between plates on two opposite longitudinal faces 12 and 13 of the bundle 1.
  • the beam On its two other longitudinal faces, the beam is surrounded by two thick sheets 6 and 7, usually made of stainless steel, so as to constitute a frame for mechanically holding the stack of plates.
  • the thin sheets constituting the plates 2 have a thickness of the order of 1 mm.
  • the thick sheets 6 and 7 have a thickness of 3 to 5 mm while in the prior art a thickness of 10 mm was necessary because these plates had to take up all the mechanical forces and support the entire vertical beam in the shell grille.
  • the exchanger described does not include any truly analogous support piece which is sufficiently resistant and welded both to the sheets 6 and 7 and to the shell 10 to connect them in a rigid structure resistant to the operating conditions.
  • spacers such as those shown in 18 and 19, constituted for example in the form of perforated or star grid, which are used to support the beam 1 in the shell of calender 10, not more when it is in vertical position and in operation, but only when it is in horizontal position for the transport of the complete exchanger. In operation, these spacers simply play the role of centering members, retaining the beam in the axis of the enclosure 3.
  • the bundle is carried suspended from the enclosure 3 at the head of the exchanger, by fluid collecting circuits.
  • the entire exchanger is supported by a base (not shown) on which the enclosure 3 rests on brackets 16 and 17, welded to it at the level of the circular weld connecting the lower cap 5 to the shell 10 in a sealed manner.
  • the charge constituting the high pressure fluid enters the bottom of the exchanger directly into the enclosure 3 by a pipe 11. It fills this enclosure and it is taken up by the passages between plates at the bottom of the beam.
  • a first manifold comprising a first connection box 21, of semi-cylindrical annular shape, connected to an external conduit 22 which passes axially through the upper calender cap 4 in a sealed manner and opens out to exterior of the exchanger by a lateral connection 14 oriented at an angle, provided at the end with a flange suitable for its connection to pipes no longer forming part of the exchanger.
  • the conduit 22, the nozzle 14 and the box 21 together form what is considered here as constituting an external collector supply circuit of the exchanger for the charge of naphtha.
  • the effluent constituting the relatively low pressure fluid enters the passages between plates at the upper end of the bundle. It leaves at the lower end by a semi-cylindrical lower connection box 24 to an axial duct 35 which completes a collector circuit for extracting the ef flow through the lower calandria cap 5.
  • a second similar upper connection box 23 is welded to the bundle at its upper end to supply the bundle with effluent from an axial internal duct 26 which guides the effluent at the crossing of the upper cap 4 constituting an internal collector circuit.
  • conduit 3 of the effluent extraction collector circuit located in the lower part of the exchanger, is interrupted by a thermal expansion compensator, constituted here by a metal bellows 25.
  • i 1 is similar to those of conventional plate heat exchangers suspended across the bundle itself, except that the nominal properties of the bellows are calculated differently.
  • the embodiment is completely different in the upper part of the exchanger, as it appears in FIGS. 1 and 2.
  • the internal effluent collecting circuit comprising the second upper connection box 23 and the internal conduit 26 is disposed axially at inside the external load supply collector circuit, at the level of the first upper connection box 21 and of the axial external duct 22.
  • a rigid assembly for hanging the beam 1 from the enclosure 3 by its end is thus formed upper, the effluent collector circuit, or internal circuit, being rigidly linked to the load collecting circuit, or external circuit, which is itself rigidly linked to the enclosure 3.
  • the rigid connections in question are produced in practice by welds, which simultaneously seal the fluids.
  • connection boxes and the sections of the external conduit 22 and the internal conduit 26 which are located inside the enclosure 3, under the upper cap 4, are advantageously made of stainless steel like the elements of the bundle itself.
  • the thickness of their walls can be relatively small, for example 25 mm for the internal collector and 4 to 6 mm for the external collector.
  • the conduits also comprise sections 27 and 28, called external sections, respectively welded end to end to the corresponding internal sections, which are inside the enclosure 3. It is at these sections 27 and 28 that the crossing takes place. of the cap 4, with sealed weld.
  • Their walls are thicker and they are made for example of chrome steel like the walls of the enclosure.
  • the section 28 of the internal collector passes through a cover 29 closing the external collector beyond the tap 14 and it ends on the outside by a coupling flange 31.
  • the internal collector with its associated connection box which mechanically supports the beam to the cover 29 closing the external collector.
  • the walls of the section of the external internal collector of the enclosure 3 in this case have a thickness that is substantially less than that of the walls of the internal collector.
  • the internal section of the conduit 22 is formed over part of its length, between the transverse lines 32 and 33, by two semi-cylindrical connecting pieces which are welded on site to close the corresponding circuit.
  • the weld zone between two sections of different metallic materials, on the conduits of the internal and external collector circuits, can have its position calculated precisely in each particular application, according to the operating conditions envisaged. In all cases it will be noted that the temperature differences to which the walls of the circuits are subjected are smaller than in the assemblies of the prior art.
  • conduit the elements of the collecting circuits which have been designated above by the term of conduit are produced essentially in the form of cylindrical tubes, in particular at the level of the crossing of the enclosure 3, at which they are sealed.
  • FIG. 4 A preferred embodiment of the invention illustrated by FIG. 4 will be described below.
