Definitions

  • the present invention relates to an arrangement comprising a cradle suspension to support a tube pendant exchanger vertical as defined in the preamble to the claim 1.
  • the invention applies in particular, for example, to support a pendant superheater in a boiler.
  • Such an exchanger includes an inlet manifold and a outlet manifold connected by vertical U-shaped tubes.
  • the tubes are grouped by heat exchanger elements a few tubes per element.
  • the tubes of the same element are arranged in the same plane and the different elements are aligned one behind the other with a certain interval.
  • such a tube pendant exchanger vertical is suspended from the frame of the building by through two suspension cradles: a cradle to support the heat exchanger elements on the side of the inlet manifold, and a cradle to support the exchanger elements on the outlet manifold side.
  • a known suspension cradle conventionally comprises two main beams located on either side of the collector and suspended from the frame by rods, and, at these main beams is hung transversely a suite of transverse supports.
  • Each transverse support is a cross, formed of two profiles in] framing the tubes of a exchanger element.
  • the two profiles are connected to their ends by pieces ensuring the spacing between the two profiles.
  • the tubes of an exchanger element rest so on this crosspiece through a socket welded on one of the tubes of the exchanger element, the tubes also being linked to each other.
  • these transverse supports constituting a series sleepers hung along the main beams, work in flexion.
  • These supports including the temperature of calculation is high (550 to 570 ° C), require to have a significant inertia and therefore significant weight.
  • the object of the present invention is to provide a suspension cradle for weight reduction.
  • the subject of the invention is therefore a cradle of suspension to support a tube pendant exchanger vertical, said exchanger comprising at least one element exchanger comprising n tubes grouped in the same plane and connected at each end to a collector, the cradle comprising two main beams located parallel to on either side of a collector and at least one support transverse hooked transversely to said beams main, a said transverse support supporting a said exchanger element, characterized in that said support transverse in the shape of a triangular frame truss points downward, said exchanger element being supported against the lower part of said farm to meet of the two branches forming said point.
  • said transverse support in the form of a farm triangular frame consists of two frames having said shape, linked to each other and framing said tubes of a said exchanger element, the support of said element heat exchanger by means of a socket welded to the central tube of said element and resting on a barrel of rectangular outer section now the spacing of the two frames of the farm at its tip lower, welded to these frames and drilled with a central hole in the outer diameter of said central tube.
  • Figure 1 is a partial perspective view of a suspension cradle of a tube pendant exchanger prior art verticals as defined in the introduction.
  • Figure 2 is a partial perspective view of a suspension cradle according to the invention.
  • Figure 3 shows the detail marked III in the figure 2.
  • Figure 1 partially shows a cradle of known suspension as defined in the introduction, a pendant exchanger.
  • This element here comprises six tubes 2. A the upper end, these tubes are connected to a collector 15. A plurality of such elements are thus arranged parallel one behind the other and all the tubes of all the elements are connected to the same collector 15. The tubes extend downwards then go up forming a U and the other end of the tubes is connected to a second collector arranged parallel to the first.
  • a complete exchanger is supported by two cradles of suspension: one at each collector.
  • Figure 1 partially shows one of these cradles.
  • Such a suspension cradle supports the exchanger just below the collector 15. It includes as said above two parallel main beams 3 located respectively on either side of the collector. On the Figure 1, only one of these two beams 3 is shown. It consists of two sections 4 and 5 in] placed back to back. They are suspended from the frame of the building by rods 6.
  • Each sleeper 7 supports an exchanger element.
  • a single cross member 7 is shown supporting element 1 of an exchanger.
  • the cross member 7 is composed of two sections 8 and 9 in [framing the tubes 2 of element 1.
  • Profiles 8 and 9 have stiffening partitions 12.
  • the exchanger element 1 is supported by the cross-member 7 by means of a socket 13 welded to one of the tubes 2 of the element and resting directly on the profiles 8.9 of the crossing.
  • the connecting pieces 10.11 maintain the spacing of the profiles 8.9 to a value equal to the diameter outside of tubes 2. All tubes 2 of element 1 are linked together by means of connection not shown.
  • the working cross member at high temperature above 500 ° C, must be very resistant to bending and has many partitions stiffening 12. This part thus has a significant weight.
  • Figure 2 thus shows a suspension cradle according to the invention, in which the cross member 7 is replaced by a transverse support 14.
  • the figure shows only one element: element 1 and therefore a single transverse support 14, but a plurality elements, not shown, are thus supported on other transverse supports aligned one behind the others and hung on the main beams 3 by by means of attachment pieces 16.17.
  • the transverse support 14 has the shape of a triangular truss of framework pointed in low.
  • a frame is formed from a sheet 20 cut in the shape of V and a connecting tube 21 connecting the upper end of the two branches of V.
  • the tip of the V has a small horizontal portion 22 for the correct support of the element 1 by one of its tubes 2, by means of a socket 23 welded to the tube and of a barrel 24 of rectangular external section now the spacing of the two frames 20-21 at their tip.
  • the Canon 24 is shown in Figure 3, it is welded to the frames. he carries a central hole corresponding to the external diameter of the tube 2.
  • element 1 rests on the tip of the V of the firm working its branches in traction, while that the horizontal bar 21 works in compression. grace in this arrangement, all of this transverse support 14 allows to gain weight, compared to the cross 7 of Figure 1 of the prior art, of the order of 40%.
