Description
La présente invention concerne un arrangement comprenant un berceau de suspension pour supporter un échangeur pendentif à tubes verticaux tel que défini dans le préambule de la revendication 1.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.
L'invention s'applique en particulier, par exemple, pour supporter un surchauffeur pendentif dans une chaudière.The invention applies in particular, for example, to support a pendant superheater in a boiler.
Un tel échangeur comprend un collecteur d'entrée et un collecteur de sortie reliés par des tubes verticaux en U.Such an exchanger includes an inlet manifold and a outlet manifold connected by vertical U-shaped tubes.
Les tubes sont groupés par éléments d'échangeur de quelques tubes par élément. Les tubes d'un même élément sont disposés dans un même plan et les différents éléments sont alignés les uns derrière les autres avec un certain intervalle.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.
D'une façon connue, un tel échangeur pendentif à tubes verticaux, est suspendu à la charpente du bâtiment par l'intermédiaire de deux berceaux de suspension : un berceau pour supporter les éléments d'échangeur du côté du collecteur d'entrée, et un berceau pour supporter les éléments d'échangeur du côté du collecteur de sortie.In a known manner, 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.
Un berceau de suspension connu comporte classiquement deux poutres principales situées de part et d'autre du collecteur et suspendues à la charpente par des tiges, et, à ces poutres principales est accrochée transversalement une suite de supports transversaux.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.
Ces supports transversaux sont ainsi disposés les uns derrière les autres et chacun supporte un élément d'échangeur. Chaque support transversal est une traverse, formée de deux profilés en ] encadrant les tubes d'un élément échangeur. Les deux profilés sont reliés à leurs extrémités par des pièces assurant l'écartement entre les deux profilés. Les tubes d'un élément d'échangeur reposent ainsi sur cette traverse par l'intermédiaire d'une douille soudée sur l'un des tubes de l'élément d'échangeur, les tubes étant par ailleurs liés les uns aux autres.These transverse supports are thus arranged one behind the others and each supports an element exchanger. 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.
Ainsi, ces supports transversaux constituant une suite de traverses accrochées le long des poutres principales, travaillent en flexion. Ces supports, dont la température de calcul est élevée (550 à 570 °C), nécessitent d'avoir une inertie importante et donc un poids important.Thus, 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.
La présente invention a pour but de proposer un berceau de suspension permettant une réduction de poids.The object of the present invention is to provide a suspension cradle for weight reduction.
L'invention a ainsi pour objet un berceau de suspension pour supporter un échangeur pendentif à tubes verticaux, ledit échangeur comportant au moins un élément d'échangeur comprenant n tubes groupés dans un même plan et reliés à chaque extrémité à un collecteur, le berceau comprenant deux poutres principales situées parallèlement de part et d'autre d'un collecteur et au moins un support transversal accroché transversalement auxdites poutres principales, un dit support transversal supportant un dit élément d'échangeur, caractérisé en ce que ledit support transversal a la forme d'une ferme triangulaire de charpente pointe en bas, ledit élément d'échangeur prenant appui contre la partie inférieure de ladite ferme à la rencontre des deux branches formant ladite pointe.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.
Selon une réalisation particulière de la présente invention, ledit support transversal en forme de ferme triangulaire de charpente est constitué de deux cadres ayant ladite forme, liés l'un à l'autre et encadrant lesdits tubes d'un dit élément d'échangeur, l'appui dudit élément d'échangeur se faisant par l'intermédiaire d'une douille soudée au tube central dudit élément et reposant sur un canon de section externe rectangulaire maintenant l'écartement des deux cadres de la ferme à sa pointe inférieure, soudé à ces cadres et percé d'un trou central au diamètre externe dudit tube central. According to a particular embodiment of this invention, 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.
On va maintenant donner la description d'un exemple de mise en oeuvre de l'invention en se reportant au dessin annexé dans lequel :We will now give the description of an example of implementation of the invention with reference to the drawing annexed in which:
La figure 1 est une vue partielle en perspective d'un berceau de suspension d'un échangeur pendentif à tubes verticaux de l'art antérieur tel que défini dans l'introduction.Figure 1 is a partial perspective view of a suspension cradle of a tube pendant exchanger prior art verticals as defined in the introduction.
La figure 2 est une vue partielle en perpective d'un berceau de suspension selon l'invention.Figure 2 is a partial perspective view of a suspension cradle according to the invention.
La figure 3 montre le détail repéré III de la figure 2.Figure 3 shows the detail marked III in the figure 2.
Ainsi, la figure 1 montre partiellement un berceau de suspension connu tel que défini dans l'introduction, d'un échangeur pendentif.Thus, Figure 1 partially shows a cradle of known suspension as defined in the introduction, a pendant exchanger.

Pour supporter l'élément 1, la traverse qui travaille à température élevée, supérieure à 500 °C, doit être très résistante à la flexion et comporte de nombreuses cloisons de raidissement 12. Cette pièce a ainsi un poids important.To support element 1, 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.
La figure 2 montre ainsi un berceau de suspension
conforme à l'invention, dans lequel la traverse 7 est
remplacée par un support transversal 14.Figure 2 thus shows a suspension cradle
