Description

La présente invention concerne un séparateur-surchauffeur vertical de vapeur comprenant à l'intérieur d'une virole commune, une partie inférieure formant zone de séparation, et une partie supérieure formant zone de surchauffe, comportant une zone axiale d'arrivée de vapeur sèche, des faisceaux tubulaires de surchauffe disposés dans des enveloppes réparties autour de la zone centrale, et fixées à une virole mince et flexible fixée elle-même à la partie supérieure de la virole commune, et une zone périphérique de collecte de la vapeur surchauffée.The present invention relates to a vertical vapor separator-superheater comprising, inside a common shell, a lower part forming a separation zone, and an upper part forming a superheating zone, comprising an axial zone for the arrival of dry vapor, tubular bundles of overheating arranged in envelopes distributed around the central zone, and fixed to a thin and flexible ferrule itself fixed to the upper part of the common ferrule, and a peripheral zone for collecting superheated steam.

Un séparateur-surchauffeur de ce genre, décrit . dans le document intercalaire FR-A2406157, permet d'absorber les dilatations et contractions des faisceaux surchauffeurs sans dispositif spécial tel que des lyres de dilatation, et facilite l'extraction éventuelle de ces faisceaux en vue de leur réparation. La disposition des éléments séparateurs groupés en plusieurs rangées parallèles d'empilements en forme de V, rend toutefois moins facile l'accès aux parois internes de la zone inférieure du séparateur-surchauffeur, et il impose par ailleurs l'orientation des tubulures d'accès de la vapeur humide à traiter, puisque celle-ci doit arriver symétriquement par rapport aux rangées d'empilements d'éléments séparateurs.A separator-superheater of this kind, described. in the intermediate document FR-A2406157, makes it possible to absorb the expansions and contractions of the superheater bundles without special device such as expansion lyres, and facilitates the possible extraction of these bundles for their repair. The arrangement of the separator elements grouped in several parallel rows of V-shaped stacks, however, makes it less easy to access the internal walls of the lower zone of the separator-superheater, and it also imposes the orientation of the access pipes. wet steam to be treated, since this must arrive symmetrically with respect to the rows of stacks of separating elements.

Une disposition des éléments séparateurs en forme d'une pyramide tronquée est connue par le document FR-A21 87394. Le mélange est admis par une chambre située au-dessous de la pyramide, ce qui augmente la hauteur de l'appareillage. Ce désavantage d'une hauteur excessive est également présent dans le dispositif selon le document FR-A 21 40 391, car on y prévoit entre deux étages de séparation une chambre d'admission pour le mélange. Cette chambre est traversée concentriquement par le tube reliant les deux étages.An arrangement of the separating elements in the form of a truncated pyramid is known from document FR-A21 87394. The mixture is admitted by a chamber located below the pyramid, which increases the height of the apparatus. This disadvantage of an excessive height is also present in the device according to document FR-A 21 40 391, because there is provided between two stages of separation an inlet chamber for the mixture. This chamber is crossed concentrically by the tube connecting the two stages.

La présente invention a pour but de procurer un séparateur-surchauffeur qui permette une excellente accessibilité à toutes les parois internes de la zone inférieure assurant la fonction de séparation, et dont les tubulures d'accès de la vapeur à traiter puissent avoir une orientation quelconque. Il a aussi pour but de procurer un ensemble d'éléments séparateurs dans lequel les organes d'évacuation de l'eau arrêtée tiennent une place très réduite.The object of the present invention is to provide a separator-superheater which allows excellent accessibility to all the internal walls of the lower zone ensuring the separation function, and whose access pipes of the steam to be treated can have any orientation. It also aims to provide a set of separating elements in which the bodies for discharging the stopped water occupy a very small space.

Le séparateur-surchauffeur selon la présente invention est caractérisé en ce que sa partie inférieure comprend une chambre annulaire d'admission de la vapeur humide, reliée à des ouvertures d'introduction de cette dernière, et des éléments séparateurs groupés en deux pyramides tronquées coaxiales, la pyramide externe ayant sa grande base à un niveau inférieur à celui de sa petite base, et la pyramide interne sa grande base à un niveau supérieur à celui de sa petite base, et la chambre annulaire étant reliée par un passage annulaire au volume intérieur à la pyramide externe, mais extérieur à la pyramide interne.The separator-superheater according to the present invention is characterized in that its lower part comprises an annular chamber for the admission of wet steam, connected to openings for introducing the latter, and separating elements grouped in two coaxial truncated pyramids, the external pyramid having its large base at a level lower than that of its small base, and the internal pyramid its large base at a level higher than that of its small base, and the annular chamber being connected by an annular passage to the interior volume at the outer pyramid, but outside the inner pyramid.

Il répond en outre de préférence à au moins l'une des caractéristiques suivantes :

  • Le passage annulaire reliant la chambre annulaire d'admission au volume compris entre les pyramides externe et interne comporte un coude à 180° environ, délimité sur un côté intérieur par des tôles séparées par des interstices permettant une séparation préliminaire d'une partie de l'eau contenue dans la vapeur humide, sous l'effet de la force centrifuge.
It also preferably meets at least one of the following characteristics:
  • The annular passage connecting the annular admission chamber to the volume between the external and internal pyramids comprises a bend at approximately 180 °, delimited on an internal side by sheets separated by interstices allowing a preliminary separation of a part of the water contained in moist steam, under the effect of centrifugal force.

Des organes d'écoulement de l'eau arrêtée dans les éléments séparateurs sont disposés aux arêtes des pyramides tronquées.Flow organs for the water stopped in the separating elements are arranged at the edges of the truncated pyramids.

Une partie du passage annulaire est formée par la paroi interne du fond de la virole commune.Part of the annular passage is formed by the internal wall of the bottom of the common ferrule.

Il est décrit ci-après, à titre d'exemples et en référence aux figures du dessin annexé, deux séparateurs-surchauffeurs de vapeur selon l'invention.It is described below, by way of examples and with reference to the figures of the appended drawing, two vapor separator-superheaters according to the invention.

La figure 1 représente une coupe axiale selon l'axe I-I de la figure 2 un séparateur-surchauffeur dans lequel le passage annulaire d'introduction de la vapeur humide vers les éléments surchauffeurs descend jusqu'au voisinage du fond de la virole, une partie de ce fond constituant une paroi du passage.FIG. 1 represents an axial section along axis II of FIG. 2 a separator-superheater in which the annular passage for the introduction of wet steam to the superheater elements descends to the vicinity of the bottom of the shell, part of this bottom constituting a wall of the passage.

La figure 2 représente une coupe diamétrale selon l'axe II-II de la figure 1.FIG. 2 represents a diametral section along the axis II-II of FIG. 1.

La figure3 représente en coupe axiale un autre séparateur-surchauffeur dans lequel le passage annulaire d'introduction de la vapeur humide est au-dessus du fond de la virole.Figure 3 shows in axial section another separator-superheater in which the annular passage for the introduction of wet steam is above the bottom of the shell.

Le séparateur-surchauffeur de la figure 1 comprend, à l'intérieur d'une virole cylindrique 1, soutenue grâce à un support annulaire habituel par un plancher 2, une partie inférieure 3 (formant séparateur) et une partie supérieure 4 (formant surchauffeur). La partie inférieure est munie de tubulures 4A d'alimentation en vapeur humide. Celles-ci débouchent dans une chambre annulaire 5 reliée à un passage annulaire 6 d'accès aux éléments séparateurs, formant un coude à 180°. Une partie de la paroi interne de ce passage est formée par la paroi 6A du fond de la virole. ceci permet de réduire la hauteur totale de la partie séparateur3, mais nécessite que la paroi 6A soit revêtue d'acier inoxydable, comme le reste de la paroi du passage, afin d'éviter le phénomène d'érosion-corrosion par la vapeur humide à vitesse élevée. L'autre partie de la paroi externe du passage est constituée par des tôles 7 décalées angulairement par rapport à l'axe vertical et séparées par des interstices 7A à des niveaux étagés, assurant une séparation préliminaire des gouttelettes d'eau sous l'effet de la force centrifuge résultant du changement de direction de la vapeur. L'eau séparée sur les tôles 7 et s'écoulant par les interstices 7A se rassemble dans le fond 8 avec l'eau retenue dans les éléments séparateurs, comme il sera indiqué plus loin, et s'évacue par la tubulure axiale 9. Les éléments séparateurs sont groupés en deux pyramides tronquées à base octogonale, la pyramide externe 10 ayant sa grande base vers le bas, et la pyramide interne 11 sa grande base vers le haut, cette dernière étant sensiblement au contact de la petite base de la pyramide externe. Il apparaît donc entre les deux pyramides un intervalle annulaire 12, de largeur décroissant vers le haut, pour l'accès de la vapeur humide aux éléments séparateurs. Ceux-ci sont analogues à ceux décrits dans le document intercalaire FR-A 2 406 157.The separator-superheater of FIG. 1 comprises, inside a cylindrical shell 1, supported by a usual annular support by a floor 2, a lower part 3 (forming a separator) and an upper part 4 (forming a superheater) . The lower part is fitted with 4A pipes for supplying wet steam. These open into an annular chamber 5 connected to an annular passage 6 for access to the separating elements, forming a 180 ° bend. Part of the internal wall of this passage is formed by the wall 6A of the bottom of the shell. this makes it possible to reduce the total height of the separator part 3, but requires that the wall 6A be coated with stainless steel, like the rest of the passage wall, in order to avoid the phenomenon of erosion-corrosion by wet steam at high speed. The other part of the external wall of the passage consists of sheets 7 angularly offset with respect to the vertical axis and separated by interstices 7A at stepped levels, ensuring a preliminary separation of the water droplets under the effect of the centrifugal force resulting from the change in direction of the vapor. The water separated on the sheets 7 and flowing through the interstices 7A collects in the bottom 8 with the water retained in the separating elements, as will be indicated further on, and is evacuated via the axial tubing 9. The separating elements are grouped in two truncated pyramids with an octagonal base, the external pyramid 10 having its large base downwards, and the internal pyramid 11 its large base upwards, the latter being substantially in contact with the small base of the external pyramid. It therefore appears between the two pyramids an annular gap 12, of decreasing width upwards, for the access of the wet steam to the separating elements. These are similar to those described in the intermediate document FR-A 2 406 157.

Les pyramides d'éléments séparateurs, sont munies le long de leurs arêtes externes d'éléments d'évacuation de l'eau séparée, tels que 13A pour la pyramide externe et 13B pour la pyramide interne. Des tôles 29 verticales, puis inclinées vers l'axe de la virole 1, assurent la collecte de l'eau et son ruissellement jusqu'au fond de la virole, au-dessus de la tubulure d'évacuation 9.The pyramids of separating elements are provided along their external edges with elements for discharging separate water, such as 13A for the external pyramid and 13B for the internal pyramid. Vertical sheets 29, then inclined towards the axis of the shell 1, collect the water and its runoff to the bottom of the shell, above the discharge pipe 9.

La vapeur séchée sortant des éléments séparateurs se réunit d'une part, dans une zone axiale 14A, d'autre part dans une zone périphérique 14B. L'ensemble s'élève alors à travers une zone intermédiaire 13 vers la partie supérieure de surchauffe 4.The dried steam leaving the separating elements meets on the one hand, in an axial zone 14A, on the other hand in a peripheral zone 14B. The assembly then rises through an intermediate zone 13 towards the upper overheating part 4.

Cette partie de surchauffe est semblable à celle décrite dans le document intercalaire FR-A 24 06 157 et ne sera donc pas décrite en détail à nouveau. Elle comporte une zone axiale 15, autour de laquelle sont disposés quatre faisceaux surchauffeurs tels que 16, 17. Ceux-ci sont fixés sur la surface interne d'une virole mince 30, elle-même soudée par son bord supérieur au fond supérieur 31 de la virole. La vapeur séchée monte donc vers la zone axiale 15, traverse ensuite radialement les faisceaux en se surchauffant et atteint par une zone périphérique 18 de collecte de la vapeur surchauffée une tubulure 19 de sortie.This overheating part is similar to that described in the intermediate document FR-A 24 06 157 and will therefore not be described in detail again. It has an axial zone 15, around which are arranged four superheater bundles such as 16, 17. These are fixed to the internal surface of a thin shell 30, itself welded by its upper edge to the upper bottom 31 of the ferrule. The dried steam therefore rises towards the axial zone 15, then passes radially through the bundles while overheating and reaches an outlet pipe 19 through a peripheral zone 18 for collecting the superheated steam.

L'alimentation des faisceaux surchauffeurs en vapeur à haute pression s'effectue par la tubulure 20, le collecteur torique 21 et les raccords 22 reliés aux chambres d'extrémité 23. La vapeur à haute pression condensée en majeure partie dans les faisceaux tubulaires tels que 16, 17 et arrivant dans les chambres d'extrémité 24, est recueillie dans le collecteur 25, puis envoyée par le conduit 26 au pot de recette 27.High pressure steam is supplied to the superheater bundles via the pipe 20, the O-manifold 21 and the fittings 22 connected to the end chambers 23. The high pressure steam condensed mainly in the tubular bundles such as 16, 17 and arriving in the end chambers 24, is collected in the collector 25, then sent via the conduit 26 to the recipe pot 27.

La figure 2 montre de façon plus précise la disposition des organes de collecte de l'eau séparée, tels que 13A, 13B, respectivement aux arêtes des pyramides externe et interne des empilements d'éléments séparateurs, donc dans les angles morts entre les séparateurs rectangulaires, dont deux seulement ont été représentés. Cette disposition permet de ne réduire que dans une faible mesure le volume utile offert, tout en assurant un écoulement satisfaisant de l'eau séparée. On voit un séparateur 32 de la pyramide tronquée externe, et un séparateur 33 de la pyramide tronquée interne. On voit par ailleurs que le système séparateur est symétrique par rapport à l'axe vertical de la virole. Ceci à pour inconvénient une légère dissymétrie dans le débit de vapeur à travers les éléments séparateurs, mais permet de disposer les tubulures d'introduction de la vapeur humide, telles que 4A, en n'importe quel point sur le pourtour de la virole, de façon à réduire la longueur de la tuyauterie d'alimentation, et assure une circulation de la vapeur séchée symétrique par rapport à l'axe vertical, ainsi qu'une excellente accessibilité à toutes les parois pour leur inspection et des réparations éventuelles tant sur le pourtour de la pyramide externe que sur celui de la pyramide interne.FIG. 2 shows more precisely the arrangement of the separate water collection members, such as 13A, 13B, respectively at the edges of the outer and inner pyramids of the stacks of separating elements, therefore in the blind spots between the rectangular separators , only two of which have been represented. This arrangement allows the useful volume offered to be reduced only to a small extent, while ensuring satisfactory flow of the separated water. We see a separator 32 of the external truncated pyramid, and a separator 33 of the internal truncated pyramid. It can also be seen that the separator system is symmetrical with respect to the vertical axis of the shell. This has the disadvantage of a slight asymmetry in the flow of steam through the separating elements, but makes it possible to arrange the pipes for introducing wet steam, such as 4A, at any point around the periphery of the shell, so as to reduce the length of the supply piping, and ensures a circulation of the dried steam symmetrical with respect to the vertical axis, as well as excellent accessibility to all the walls for their inspection and possible repairs both around the perimeter of the outer pyramid than on that of the inner pyramid.

La figure 3 représente un séparateur-surchauffeur analogue à celui des figures 1 et 2, mais dans lequel le passage 6 de la vapeur humide des tubulures d'entrée aux éléments séparateurs est plus éloigné du fond de la virole. Les organes identiques ne seront donc pas décrits à nouveau. Dans ce cas, il n'est pas nécessaire de disposer un revêtement interne d'acier inoxydable sur la partie du fond de la virole au contact de la vapeur humide entrante. Le passage 6 imprime toujours à la vapeur humide un coude à 180°, ce qui permet une séparation préliminaire des gouttelettes d'eau sur les tôles 7 délimitant le passage, avec évacuation de l'eau par les interstices 7A entre ces tôles.FIG. 3 represents a separator-superheater similar to that of FIGS. 1 and 2, but in which the passage 6 of the wet steam from the inlet pipes to the separating elements is more distant from the bottom of the shell. The identical members will therefore not be described again. In this case, it is not necessary to have an internal coating of stainless steel on the bottom part of the shell in contact with the incoming wet steam. The passage 6 always prints a 180 ° bend with wet steam, which allows a preliminary separation of the water droplets on the sheets 7 delimiting the passage, with evacuation of the water by the interstices 7A between these sheets.

Le nombre de côtés des pyramides tronquées formées par les empilements de séparateurs peut être inférieur ou supérieur à huit. On peut prévoir un soutirage partiel de vapeur séchée avant son introduction dans la zone de surchauffe.The number of sides of the truncated pyramids formed by the stacks of separators may be less than or greater than eight. It is possible to provide for a partial withdrawal of dried steam before it is introduced into the overheating zone.
