Description
La présente invention concerne les condenseurs de vapeur. On sait qu'un condenseur de vapeur pour centrale électrique est constitué par un ensemble de tubes réunis à chacune de leurs extrémités par une plaque tubulaire, l'ensemble étant placé dans un corps de condenseur réuni à l'échappement des turbines et une boite à eau étant fixée à chaque plaque tubulaire.The present invention relates to steam condensers. It is known that a steam condenser for a power plant is constituted by a set of tubes joined at each of their ends by a tubular plate, the assembly being placed in a condenser body joined to the exhaust of the turbines and a box water being attached to each tube plate.
Habituellement, le montage des tubes dans les plaques tubulaires et leur dudgeonnage ou soudage s'effectue sur le site de la centrale ; or, cette opération est de longue durée, le nombre de tubes à enfiler étant considérable.Usually, the mounting of the tubes in the tube plates and their expansion or welding is carried out on the site of the central; however, this operation is of long duration, the number of tubes to be threaded being considerable.
On a donc cherché à réaliser des faisceaux tubulaires modulaires construits en usine de façon à limiter au maximum le nombre d'opération à réaliser sur le chantier et donc le temps passé sur le site.We have therefore sought to produce modular tubular bundles built in the factory so as to limit as much as possible the number of operations to be carried out on the site and therefore the time spent on the site.
Les figures 1 et 2 montrent ainsi un exemple de réalisation connu, réalisé à la centrale de San Onofré aux Etats-Unis en Californie, d'un condenseur de vapeur dans lequel le faisceau tubulaire, comprenant des tubes 1 et deux plaques tubulaires 2 et 3, est réalisé en usine puis assemblé, sur le site, au corps de condenseur 4.Figures 1 and 2 thus show a known embodiment, produced at the San Onofré power plant in the United States in California, of a steam condenser in which the tube bundle, comprising
Le faisceau tubulaire est réalisé en quatre modules assemblés au moment du montage. Sur place, avant l'arrivée des quatre modules le corps se termine à droite par des pièces 5 et 6. La pièce 6 quatre fenêtres connue le montre la figure 2 et sert à l'assemblage des modules. A gauche, le corps se termine en 7. La plaque tubulaire 3 de chaque module est reliée à un cadre 8 au moyen de vis 9 ; à chaque cadre 8 sont soudées des pièces 10 et 11 sur les faces adéquates de manière à fermer le corps de condenseur. Sur place, la boite à eau 12 de gauche se termine par une plaque 13 dont la forme est également représentée sur la figure 2. Cette plaque sert à l'assemblage des quatre plaques tubulaires 3.The tube bundle is made up of four modules assembled at the time of assembly. On site, before the arrival of the four modules, the body ends on the right with
Le montage s'effectue donc de la manière suivante : chaque module comprend à droite uniquement la plaque tubulaire 2 et à gauche, outre la plaque tubulaire 3, les pièces 8, 10 et 11. Le module ainsi composé est introduit de la droite vers la gauche à travers l'une des quatre fenêtres de la pièce 6 jusqu'à ce que la plaque tubulaire 2 vienne en butée contre la pièce 6, par l'intermédiaire d'un joint 18. On fixe alors l'ensemble au moyen de vis 15 et on fait la soudure 17 qui relie les plaques 11 au corps 4. On vient ensuite fixer la boîte à eau 12, 13 au moyen de vis 16.The assembly is therefore carried out as follows: each module comprises on the right only the
Des joints 18 et 19 sont placés respectivement entre la plaque tubulaire 2 et la pièce 6 et entre la plaque tubulaire 3 et les cadres 8, et un joint 14 est également placé entre le cadre 13 et la plaque tubulaire 3.
Cette construction présente des inconvénients. En particulier, les joints 18 et 19, une fois le montage effectué et la soudure 17 réalisée, sont absolument invisitables ; la soudure 17 est à réaliser sur le chantier ; l'ensemble est asymétrique. Les modules, avant leur montage, manquent de rigidité.This construction has drawbacks. In particular, the
La présente invention a pour but de pallier ces inconvénients et de proposer une solution plus satisfaisante, plus pratique et plus sûre.The present invention aims to overcome these drawbacks and to provide a more satisfactory, more practical and safer solution.
L'invention a ainsi pour objet un faisceau tubulaire modulaire pour condenseur de vapeur comprenant deux plaques tubulaires, une série de tubes reliant les deux plaques tubulaires et un ensemble de plaques entretoises supports réparties entre les deux plaques tubulaires, caractérisé en ce que les deux plaques tubulaires ont la même dimension, chacune étant entourée d'un cadre renfort plus épais que ladite plaque tubulaire et en ce que des tirants, pourvus de moyens de réglage de leur longueur, réunissent les deux plaques tubulaires, lesdits tirants étant fixés sur lesdits cadres et répartis le long des cadres.The subject of the invention is therefore a modular tubular bundle for a steam condenser comprising two tubular plates, a series of tubes connecting the two tubular plates and a set of support spacer plates distributed between the two tubular plates, characterized in that the two plates tubulars have the same dimension, each being surrounded by a thicker reinforcement frame than said tubular plate and in that tie rods, provided with means for adjusting their length, join the two tubular plates, said tie rods being fixed on said frames and distributed along the frames.
L'invention a aussi pour objet un condenseur de vapeur comprenant une enveloppe contenant un faisceau tubulaire associé à chaque extrémité à une boite à eau, caractérisé en ce que ledit faisceau tubulaire est réalisé par l'assemblage en parallèle de n dits faisceaux tubulaires modulaires.The invention also relates to a steam condenser comprising an envelope containing a tubular bundle associated at each end with a water box, characterized in that said tubular bundle is produced by the parallel assembly of n said modular tubular bundles.
Selon une réalisation préférée de l'invention, l'assemblage des n faisceaux tubulaires modulaires est réalisé à chaque extrémité de l'ensemble à relier, au moyen d'une bride d'assemblage à n fenêtres, prenant appui contre le cadre de renfort de chaque faisceau modulaire, du côté extérieur par rapport aux tubes et fixé à ces cadres, le périmètre extérieur de la bride comportant un rebord externe s'étendant au-delà du périmètre extérieur du faisceau tubulaire assemblé, ladite bride étant fixé le long de ce dit bord externe contre un flasque fixé à ladite enveloppe du condenseur, la dimension de passage à l'intérieur dudit flasque étant identique de chaque côté du condenseur.According to a preferred embodiment of the invention, the assembly of the n modular tubular bundles is carried out at each end of the assembly to be connected, by means of an assembly flange with n windows, bearing against the reinforcing frame of each modular bundle, on the external side with respect to the tubes and fixed to these frames, the external perimeter of the flange having an external rim extending beyond the external perimeter of the assembled tube bundle, said flange being fixed along said outer edge against a flange fixed to said casing of the condenser, the passage dimension inside said flange being identical on each side of the condenser.

La figure 3 montre ainsi un faisceau tubulaire modulaire selon l'invention. Il comprend deux plaques tubulaires 20 et 21, un ensemble de tubes 22 et un ensemble de plaques entretoises supports 23. Chaque plaque tubulaire est entourée d'un cadre renfort : 24 pour la plaque tubulaire 20 et 25 pour la plaque tubulaire 21. Ces cadres renforts sont soudés à leur plaque tubulaire respective. Enfin, une série de tirants 26 relient les deux plaques et permettent grâce à un moyen de réglage de leur longueur, représenté en vue agrandie figure 4 d'ajuster exactement l'écartement des plaques. Les tirants sont espacés d'environ 500 mm. Au moins certaines des plaques entretoises supports 23 sont reliées aux tirants 26 pour aeeroitre la rigidité de l'ensemble. Le système de réglage comprend un manchon 27 comportant un alésage le traversant de part en part et taraudé d'un côté avec un pas à droite et de l'autre avec un pas à gauche. Les tirants 26 sont en deux parties 26a et 26b se vissant dans le manchon.

Cette figure 5 ne représente qu'une petite partie mais l'ensemble est symétrique, l'assemblage étant identique à droite et à gauche ainsi qu'en haut et en bas.This figure 5 represents only a small part but the whole is symmetrical, the assembly being identical on the right and on the left as well as above and below.
Les modules sont assemblés entre eux au moyen d'une bride 31 prenant appui sur les quatre cadres 25 des quatre modules que l'on veut assembler. La figure 6 montre la géométrie de cette bride 31. La fixation est réalisée au moyen de goujons 32 passant dans des trous 32a de la bride 31, et d'écrous 33. Deux joints 34 et 35 sont interposés sur le pourtour de chaque cadre 25 de chaque module entre la bride 31 et les cadres 25 respectifs.The modules are assembled together by means of a
