Description

Structure de condenseur horizontal et chaufferie nucléaire comportant au moins une telle structureHorizontal condenser structure and nuclear boiler plant comprising at least one such structure

La présente invention concerne une structure de condenseur horizontal à tubes. L’invention concerne également une chaufferie nucléaire comportant au moins une telle structure de condenseur.The present invention relates to a horizontal tube condenser structure. The invention also relates to a nuclear boiler with at least one such condenser structure.

Il existe déjà dans l’état de la technique, des structures de condenseur horizontal à tubes qui comportent au moins une entrée et une sortie, au moins un faisceau de tubes et au moins un puits de collecte de condensât.In the state of the art, there are already horizontal tube condenser structures which comprise at least one inlet and one outlet, at least one bundle of tubes and at least one condensate collection well.

En règle générale, les faisceaux de tubes sont relativement compacts et les entrées et sorties mentionnées précédemment sont disposées dans les parties supérieure et inférieure de ces faisceaux.As a rule, the bundles of tubes are relatively compact and the inputs and outputs mentioned above are arranged in the upper and lower parts of these bundles.

Mais ces structures présentent un certain nombre d’inconvénients.But these structures have a number of disadvantages.

En effet, dans de telles structures, il est difficile d’alimenter les rangées de tubes inférieures.Indeed, in such structures, it is difficult to feed the rows of lower tubes.

Par ailleurs, on assiste également à un engorgement des tubes, notamment dans les parties basses de la structure, par le ruissellement s’opérant sur l’ensemble des rangées de tubes.In addition, there is also a clogging of the tubes, especially in the lower parts of the structure, by runoff occurring on all rows of tubes.

Des détériorations de tubes ont également été constatées sous l’effet par exemple de la projection de gouttelettes contenues dans la vapeur entrante.Pipe deterioration has also been noted under the effect for example of the projection of droplets contained in the incoming vapor.

Le but de l'invention est donc de résoudre ces problèmes en proposant une structure dont le fonctionnement soit optimisé et qui permette de limiter le ruissellement créé et de mieux évacuer le condensât.The aim of the invention is therefore to solve these problems by proposing a structure whose operation is optimized and which makes it possible to limit the runoff created and to better evacuate the condensate.

De plus, l’invention vise également à mieux protéger les tubes de l’impact des gouttelettes contenues dans la vapeur entrante et à améliorer la distribution de la vapeur au sein du condenseur. A cet effet, l’invention a pour objet une structure de condenseur horizontal à tubes, comportant au moins une entrée et une sortie, au moins un faisceau de tubes et au moins un puits de collecte de condensât, caractérisée en ce que le faisceau de tubes est divisé en sections de faisceau superposées, entre lesquelles sont placées des plaques de répartition de la vapeur sur la section de faisceau inférieure correspondante et de canalisation des condensats de la section de faisceau supérieure correspondante vers le puits de collecte.In addition, the invention also aims to better protect the tubes from the impact of the droplets contained in the incoming vapor and to improve the distribution of steam within the condenser. For this purpose, the subject of the invention is a horizontal tube condenser structure, comprising at least one inlet and one outlet, at least one tube bundle and at least one condensate collection well, characterized in that the bundle of The tubes are divided into superimposed beam sections, between which are placed steam distribution plates on the corresponding lower bundle and condensate pipe section of the corresponding upper bundle section towards the collection well.

Selon d’autres caractéristiques de la structure selon l’invention, prises seules ou en combinaison : - le faisceau de tubes est inscrit dans une section au moins en partie circulaire de cette structure ; - ladite entrée et ladite sortie sont désaxées et tangentes à cette structure ; - les plaques sont inclinées en direction de la sortie de condensais pour optimiser la répartition de vapeur sur les sections de faisceau et la récupération des condensais et leur canalisation vers le puits.According to other characteristics of the structure according to the invention, taken alone or in combination: the bundle of tubes is inscribed in an at least partly circular section of this structure; said input and said output are off-axis and tangent to this structure; the plates are inclined towards the condensate outlet to optimize the steam distribution on the beam sections and the recovery of the condensates and their channeling to the well.

Selon un autre aspect, l’invention a également pour objet une chaufferie nucléaire, comportant au moins une telle structure de condenseur. L’invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d’exemple et faite en se référant au dessin annexé qui représente une vue en coupe schématique illustrant la structure et le fonctionnement d’une structure de condenseur horizontal à tubes selon l’invention.In another aspect, the invention also relates to a nuclear boiler, comprising at least one such condenser structure. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawing, which represents a schematic sectional view illustrating the structure and operation of a condenser structure. horizontal tube according to the invention.

On a en effet illustré sur cette figure, une structure de condenseur horizontal à tubes.In fact, this figure shows a horizontal condenser structure with tubes.

Cette structure est désignée par la référence générale 1 et comporte au moins une entrée et une sortie désignées respectivement par les références 2 et 3 sur cette figure. L’entrée est ainsi par exemple illustrée sur la figure en haut à gauche de la structure et la sortie à l’opposé en bas et à droite de celle-ci.This structure is designated by the general reference 1 and comprises at least one input and one output designated respectively by the references 2 and 3 in this figure. The entry is thus for example shown in the figure at the top left of the structure and the output opposite to the bottom right of it.

Cette structure comporte également au moins un faisceau de tubes, désigné par la référence générale 4 sur cette figure, et qui sera décrit plus en détail par la suite, et au moins un puits de collecte de condensât désigné par la référence générale 5 et débouchant au niveau de la sortie 3.This structure also comprises at least one bundle of tubes, designated by the general reference 4 in this figure, which will be described in more detail below, and at least one condensate collection well designated by the general reference 5 and opening at level of the output 3.

Selon l’invention, le faisceau de tubes 4 est divisé en sections de faisceau superposées.According to the invention, the bundle of tubes 4 is divided into superimposed beam sections.

Ainsi par exemple dans la figure, le faisceau de tubes 4 est divisé en trois sections de faisceau superposées, désignées respectivement par les références 6, 7 et 8, pour des sections haute, intermédiaire et basse.Thus for example in the figure, the bundle of tubes 4 is divided into three superimposed beam sections, designated respectively by the references 6, 7 and 8, for high, intermediate and low sections.

Des espaces sont ménagés entre ces sections de faisceau.Spaces are formed between these beam sections.

En effet, des plaques désignées par les références 9 et 10 sont placées dans ces espaces respectivement entre les sections de faisceau 6, 7 et 8.Indeed, plates designated by the references 9 and 10 are placed in these spaces respectively between the beam sections 6, 7 and 8.

Ces plaques sont en fait des plaques de répartition de la vapeur sur la section de faisceau inférieure correspondante et de canalisation des condensais de la section de faisceau supérieure correspondante vers le puits de collecte 5.These plates are in fact steam distribution plates on the corresponding lower beam section and condensate channel of the corresponding upper beam section towards the collection well 5.

Ainsi par exemple la plaque 9 permet d’une part de répartir correctement la vapeur sur la section de faisceau inférieure 7 et d’autre part de canaliser les condensais de la section de faisceau supérieure 6 vers le puits 5 et la sortie 3.For example, the plate 9 makes it possible on the one hand to correctly distribute the steam on the lower beam section 7 and on the other hand to channel the condensates of the upper beam section 6 towards the well 5 and the outlet 3.

Il en est de même pour la plaque 10 pour la section inférieure 8 et la section supérieure 7 de faisceau.It is the same for the plate 10 for the lower section 8 and the upper beam section 7.

Comme cela est illustré, le faisceau de tubes 4 est par exemple inscrit dans une section au moins en partie circulaire de la structure 1.As illustrated, the bundle of tubes 4 is for example inscribed in an at least partly circular section of the structure 1.

En fait, l’entrée 2 et la sortie 3 sont par exemple désaxées et tangentes à cette structure.In fact, the input 2 and the output 3 are, for example, off-axis and tangent to this structure.

Comme cela est également illustré sur cette figure, les plaques 9 et 10 sont inclinées en direction du puits de collecte 5 et de la sortie de condensât 3, pour optimiser la répartition de vapeur sur les sections de faisceau et la récupération des condensats et leur canalisation vers le puits.As is also illustrated in this figure, the plates 9 and 10 are inclined towards the collection well 5 and the condensate outlet 3, to optimize the steam distribution on the beam sections and the recovery of the condensates and their channelization towards the well.

On conçoit alors qu’une telle structure permet d’améliorer la répartition de vapeur sur les sections de faisceau tout en améliorant la canalisation des condensats et leur évacuation.It is conceivable that such a structure improves the distribution of steam on the beam sections while improving the pipe condensate and their evacuation.

Ceci permet également de résoudre les différents problèmes qui ont été évoqués précédemment à propos du ruissellement et de l’impact des gouttes sur les faisceaux. L’engorgement de la structure est également évité.This also makes it possible to solve the various problems that have been mentioned previously about the runoff and the impact of the drops on the beams. Clogging of the structure is also avoided.

Une telle structure de condenseur trouve des applications notamment dans des chaufferies nucléaires qui comportent une ou plusieurs structures de ce type.Such a condenser structure finds applications in particular in nuclear boilers which comprise one or more structures of this type.

Bien entendu d’autres modes de réalisation encore et d’autres applications peuvent être envisagés.Of course, still other embodiments and other applications can be envisaged.
