Description

La présente invention concerne un réfrigérant atmosphérique à ruissellement.The present invention relates to an atmospheric trickle refrigerant.

Elle concerne tout particulièrement un réfrigérant atmosphérique à ruissellement du type comprenant une coque présentant des ouvertures d'entréed'air inférieures périphériques et, disposés à l'intérieur de cette coque, un réseau de distribution d'un liquide à refroidir, un corps de mise en contact s'étendant sous le réseau de distribution et des dispositifs récepteurs du liquide, à goulottes, disposés sous le corps de mise en contact.It relates more particularly to an atmospheric trickle refrigerant of the type comprising a shell having peripheral lower air inlet openings and, arranged inside this shell, a distribution network for a liquid to be cooled, a setting body. in contact extending under the distribution network and liquid receiving devices, with chutes, arranged under the contacting body.

Un réfrigérant de ce type a été décrit notamment dans le brevet FR N° 876525.A refrigerant of this type has been described in particular in patent FR No. 876525.

Les réfrigérants de ce type trouvent une application notamment dans les réfrigérations des eaux de centrales électriques. Actuellement, dans ces réfrigérants, la coque en forme de tour repose sur des piliers obliques solidaires les uns des autres. Par ailleurs, dans ces réfrigérants, l'eau à refroidir arrive au centre de la tour et est récupérée après ruissellement par les goulottes qui renvoient l'eau refroidie à nouveau vers le centre de la tour d'où elle est évacuée.Refrigerants of this type find application in particular in the refrigeration of water from power plants. Currently, in these refrigerants, the tower-shaped shell rests on oblique pillars integral with each other. Furthermore, in these refrigerants, the water to be cooled arrives at the center of the tower and is recovered after runoff by the chutes which return the cooled water again to the center of the tower from where it is discharged.

L'utilisation de piliers obliques est apparue ne pas être une solution totalement satisfaisante. En effet, dans le cas où les terrains ont une stabilité irrégulière, il risque de se produire des tassements différentiels conduisant à une inclinaison de la tour.The use of oblique abutments appeared not to be a completely satisfactory solution. Indeed, in the case where the terrains have an irregular stability, there is a risk of differential settlements leading to an inclination of the tower.

On a proposé de remédier à cet inconvénient par l'utilisation de piles indépendantes régulièrement réparties à la périphérie du réfrigérant sur lesquelles repose la coque du réfrigérant.It has been proposed to remedy this drawback by the use of independent batteries regularly distributed around the periphery of the refrigerant on which the shell of the refrigerant rests.

La présence d'un bassin central d'évacuation de l'eau refroidie limite la zone de mise en contact, ainsi que l'alimentation en air sous cette zone de mise en contact. Cette présence pose également des problèmes de nature hydraulique en raison notamment du tourbillon qui tend à se produire dans ce bassin.The presence of a central basin for evacuating the cooled water limits the contacting zone, as well as the air supply under this contacting zone. This presence also poses hydraulic problems due in particular to the vortex which tends to occur in this basin.

Par ailleurs, cette présence entraîne la construction d'un talus tronconique de support des charges, talus qui est très gênant pour les opérations de montage des dispositifs internes aux réfrigérants et pour celles de maintenance.Furthermore, this presence leads to the construction of a frustoconical embankment for supporting the charges, an embankment which is very troublesome for the operations of mounting the devices internal to the refrigerants and for those of maintenance.

En outre, les vannes permettant le contourne- _ ment, c'est-à-dire le passage direct de l'arrivée d'eau chaude à la sortie d'eau froide, sont d'un accès difficile.In addition, the valves allowing the bypass, that is to say the direct passage from the hot water inlet to the cold water outlet, are difficult to access.

La présente invention vise à remédier à ces différents inconvénients.The present invention aims to remedy these various drawbacks.

A cet effet, elle a pour objet un réfrigérant atmosphérique à ruissellement du type comportant une coque reposant sur des piles indépendantes régulièrement réparties à la périphérie et, disposés à l'intérieur de cette coque, un réseau de distribution d'un liquide à refroidir, un corps de mise en contact s'étendant sous le réseau de distribution et des dispositifs récepteurs du liquide, à goulottes, disposés sous le corps de mise en contact, caractérisé en ce que la coque du réfrigérant repose sur les piles par l'intermédiaire d'un linteau périphérique large, qui comporte, à sa partie supérieure, un rebord interne et un rebord externe formant un bassin périphérique dans lequel est évacué par gravité le liquide refroidi recueilli dans les goulottes.To this end, it relates to an atmospheric trickle refrigerant of the type comprising a shell resting on independent batteries regularly distributed at the periphery and, arranged inside this shell, a distribution network for a liquid to be cooled, a contacting body extending under the distribution network and liquid receiving devices, with chutes, arranged under the contacting body, characterized in that the shell of the refrigerant rests on the batteries by means of 'a wide peripheral lintel, which has, at its upper part, an internal rim and an external rim forming a peripheral basin in which is evacuated by gravity the cooled liquid collected in the chutes.

L'utilisation d'un linteau large reposant sur des piles permet, à la fois, d'améliorer la stabilité du réfrigérant atmosphérique et, d'autre part, de simplifier la construction et le fonctionnement de ce réfrigérant.The use of a wide lintel resting on batteries makes it possible both to improve the stability of the atmospheric refrigerant and, on the other hand, to simplify the construction and the operation of this refrigerant.

Dans un mode particulier de la présente invention, le rebord interne du bassin périphérique peut être formé par la coque elle-même. Dans ce cas, la coque comporte avantageusement un bac périphérique interne communiquant avec le bassin périphérique, de façon à recueillir l'eau ruisselant sur la paroi interne de la coque et à l'évacuer vers le bassin périphérique.In a particular embodiment of the present invention, the internal rim of the peripheral basin can be formed by the shell itself. In this case, the shell advantageously comprises an internal peripheral tank communicating with the peripheral basin, so as to collect the water flowing on the internal wall of the shell and to discharge it towards the peripheral basin.

La coque peut également reposer sur le linteau périphérique par l'intermédiaire de piliers, le rebord interne du bassin périphérique étant alors situé à l'intérieur du réfrigérant, en deçà de la verticale du bas de la coque, de façon à recueillir les eaux ruisselant sur la paroi interne de la coque.The hull can also rest on the peripheral lintel by means of pillars, the internal rim of the peripheral basin then being located inside the cooler, below the vertical of the bottom of the hull, so as to collect the water flowing on the inner wall of the hull.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant des modes de réalisation particuliers. Sur ces dessins:

  • la fig. 2 est une vue suivant 2-2 de la fig. 1 ;

  • La fig. 1 représente un réfrigérant atmosphérique 1 selon la présente invention, en coupe horizontale, la coupe étant effectuée à trois niveaux différents, à savoir: au niveau des piles, au niveau des goulottes et au niveau du réseau de distribution du liquide à refroidir.
The invention is set out below in more detail with the aid of drawings representing particular embodiments. In these drawings:
  • fig. 1 is a horizontal sectional view at different levels of an atmospheric refrigerant according to the present invention;
  • fig. 2 is a view along 2-2 of FIG. 1;
  • fig. 3 is a section on 3-3 of FIG. 1;
  • fig. 4 is a section along 4-4 of FIG. 1;
  • fig. 5 is a section of the same type as that shown in FIG. 3, but of a variant of the invention;
  • fig. 6 is a section of the same type representing another variant of the present invention.
  • Fig. 1 represents an atmospheric refrigerant 1 according to the present invention, in horizontal section, the cutting being carried out at three different levels, namely: at the level of the piles, at the level of the chutes and at the level of the distribution network of the liquid to be cooled.

Le réfrigérant atmosphérique 1 est en forme de tore hyperboloïque et repose sur une série de piles 2 reposant elles-mêmes sur des socles 3. Les piles 2 sont régulièrement réparties à la périphérie du réfrigérant atmosphérique. En section horizontale, leur plus grande dimension est orientée suivant des rayons; leur section comprend une partie rectangulaire centrale et est terminée en amont et en aval par une partie arrondie.The atmospheric refrigerant 1 is in the form of a hyperboloic torus and rests on a series of batteries 2 themselves resting on bases 3. The batteries 2 are regularly distributed around the periphery of the atmospheric refrigerant. In horizontal section, their largest dimension is oriented along radii; their section comprises a central rectangular part and is terminated upstream and downstream by a rounded part.

Comme représenté sur les fig. 1 6, sur l'ensemble des piles 2 repose un linteau 4 annulaire légèrement plus large que la plus grande dimension des piles en section. Ce linteau très rigide repose sur les piles 2 par l'intermédiaire de cales d'appui 5.As shown in fig. 1 6, on all the stacks 2 rests an annular lintel 4 slightly wider than the largest dimension of the stacks in section. This very rigid lintel rests on the piles 2 by means of support wedges 5.

Dans le mode de réalisation représenté sur les fig. 1, 2, 3, 4 et 6, sur la partie interne de ce linteau, repose la partie inférieure de la coque 6 du réfrigérant atmosphérique. Le linteau 4 comprend, par ailleurs, à sa partie supérieure, un rebord externe 7 qui forme avec le linteau 4 et la partie inférieure de la coque 6 un bassin 8 qui est destiné à recueillir le liquide refroidi.In the embodiment shown in FIGS. 1, 2, 3, 4 and 6, on the internal part of this lintel, rests the lower part of the shell 6 of the atmospheric refrigerant. The lintel 4 further comprises, at its upper part, an external rim 7 which forms with the lintel 4 and the lower part of the shell 6 a basin 8 which is intended to collect the cooled liquid.

Comme représenté sur la fig. 1, le liquide à refroidir (généralement de l'eau) est amené depuis le sol par deux colonnes verticales 9 disposées au voisinage du centre du réfrigérant atmosphérique. Le liquide arrivant par ces colonnes 9 est alors déversé dans deux canaux de distribution 10 (ou galeries) sensiblement horizontaux qui sont munis de tubes latéraux 11 de distribution du liquide à refroidir, eux-mêmes munis d'un grand nombre de buses de pulvérisation. Sous ces tubes de distribution 11 sont disposés des éléments de garnissage 12 assurant le contact entre le liquide à refroidir et l'air entrant à la partie inférieure du réfrigérant entre les piles 2. Sous ces éléments de garnissage 12 est disposée une série de parois inclinées 13 se terminant par des goulottes 14. Ces goulottes 14 sont disposées suivant deux pentes permettant leur déversement dans un collecteur 15 passant par le centre du réfrigérant. Ce collecteur 15 débouche lui-même, par un orifice 16, dans le bassin périphérique 8.As shown in fig. 1, the liquid to be cooled (generally water) is brought from the ground by two vertical columns 9 arranged in the vicinity of the center of the atmospheric refrigerant. The liquid arriving through these columns 9 is then poured into two substantially horizontal distribution channels 10 (or galleries) which are provided with lateral tubes 11 for distributing the liquid to be cooled, themselves provided with a large number of spray nozzles. Under these distribution tubes 11 are arranged packing elements 12 ensuring the contact between the liquid to be cooled and the air entering the lower part of the refrigerant between the batteries 2. Under these packing elements 12 is arranged a series of inclined walls 13 ending in chutes 14. These chutes 14 are arranged on two slopes allowing their discharge into a collector 15 passing through the center of the refrigerant. This collector 15 opens itself, through an orifice 16, into the peripheral basin 8.

Sur la paroi interne de la coque est disposé un bac périphérique 17, sensiblement au niveau des goulottes 14, qui communique avec le bassin périphérique 8 par des orifices 18. Comme représenté sur les fig. 1 et 2, le bassin périphérique 8 comporte une sortie 19 du liquide refroidi disposée sensiblement dans le prolongement du collecteur 15. Cette sortie amène le liquide refroidi vers une conduite 20. Elle possède un système à batardeaux 21 permettant la commande de la sortie du liquide refroidi du bassin périphérique 8.On the inner wall of the shell is disposed a peripheral tank 17, substantially at the level of the troughs 14, which communicates with the peripheral basin 8 through orifices 18. As shown in FIGS. 1 and 2, the peripheral basin 8 has an outlet 19 for the cooled liquid disposed substantially in the extension of the manifold 15. This outlet brings the cooled liquid to a pipe 20. It has a cofferdam system 21 allowing the control of the outlet of the liquid cooled from the peripheral basin 8.

Comme représenté sur les fig. 1 et 4, les canaux de distribution 10 traversent la coque 6 et débouchent au-dessus du bain périphérique 8. Leur extrémité est munie d'une vanne de by-pass 22. L'ouverture de cette vanne 22 permet d'évacuer directement le liquide à refroidir dans le bassin périphérique 8 en abaissant alors suffisamment le niveau du liquide pour ne plus envoyer de liquide dans les tubes de distribution 11. Un tel contournement est destiné notamment à permettre un arrêt rapide de l'écoulement de l'eau parvenant sur les éléments de garnissage en cas de période de froid intense pour éviter la formation de gel sur ces éléments de garnissage.As shown in fig. 1 and 4, the distribution channels 10 pass through the shell 6 and open out above the peripheral bath 8. Their end is provided with a by-pass valve 22. The opening of this valve 22 makes it possible to directly evacuate the liquid to be cooled in the peripheral basin 8 while lowering the level of the liquid sufficiently enough to no longer send liquid into the distribution tubes 11. Such a bypass is intended in particular to allow rapid stopping of the flow of water reaching the packing elements in the event of an intense cold period to avoid the formation of gel on these packing elements.

On a représenté sur la fig. 5 un autre mode de réalisation de l'invention. Dans ce mode de réalisation, la coque 6 repose sur le linteau périphérique 4 par l'intermédiaire de piliers 23 régulièrement espacés. Le linteau 4 comporte alors à sa partie supérieure un rebord interne 24 situé à l'intérieur du réfrigérant, en deçà de la verticale du bas de la coque 6, formant avec le linteau proprement dit et le rebord externe 7 un bac périphérique 8. Ce mode de réalisation permet de supprimer le bac périphérique 17.There is shown in FIG. 5 another embodiment of the invention. In this embodiment, the shell 6 rests on the peripheral lintel 4 by means of pillars 23 regularly spaced. The lintel 4 then has at its upper part an internal rim 24 located inside the refrigerant, below the vertical of the bottom of the shell 6, forming with the lintel proper and the external rim 7 a peripheral tank 8. This embodiment makes it possible to delete the peripheral tray 17.

On a représenté sur la fig. 6 un autre mode de réalisation de l'écoulement du liquide refroidi depuis les goulottes 14 jusqu'au bassin périphérique 8. Dans ce mode de réalisation les goulottes 14 traversent la paroi de la coque 6 et débouchent dans le bassin périphérique 8. Le bac périphérique et le collecteur central sont supprimés et la pente des goulottes 14 est en sens inverse, c'est-à-dire que leur débouché inférieur est du côté de la coque 6.There is shown in FIG. 6 another embodiment of the flow of the cooled liquid from the troughs 14 to the peripheral basin 8. In this embodiment the troughs 14 pass through the wall of the shell 6 and open into the peripheral basin 8. The peripheral tank and the central manifold are eliminated and the slope of the troughs 14 is in the opposite direction, that is to say that their lower outlet is on the side of the shell 6.

Comme cela a déjà été indiqué, le réfrigérant atmosphérique selon la présente invention présente de nombreux avantages par rapport à la technique antérieure.As already indicated, the atmospheric refrigerant according to the present invention has many advantages over the prior art.

Tout d'abord, le liquide refroidi qui est présent dans le bassin périphérique 8 contribue à répartir les efforts sur les différentes piles 2. Par ailleurs, le liquide refroidi qui sort dans le bassin périphérique 8 protège le linteau des variations thermiques .brusques et évite ainsi les fissurations du linteau. Il en est de même, dans une certaine mesure, pour la partie inférieure de la coque 6, dont la paroi extérieure est chauffée par le liquide refroidi et la vapeur qui s'en dégage encore. Comme autres avantages particuliers, on peut noter:

  • - un rendement amélioré du réfrigérant atmosphérique grâce à une meilleure alimentation en air des éléments de garnissage de la zone centrale;
  • - la suppression des conduites de sortie d'eau sous le réfrigérant atmosphérique et du bassin central d'eau refroidie;
  • - la suppression des talus tronconiques supportant les bassins d'eau froide utilisés traditionnellement;
  • - l'accessibilité des organes de réglage, tels que les batardeaux;
  • - la simplification des systèmes de contournement permettant notamment un arrêt rapide du ruissellement en période de froid intense;
  • - la possibilité de supprimer les bacs périphériques en utilisant un mode de réalisation comme représenté sur la fig. 5;
  • - la possibilité de supprimer les collecteurs de liquide refroidi, en utilisant un mode de réalisation comme représenté sur la fig. 6.
First of all, the cooled liquid which is present in the peripheral basin 8 contributes to distribute the forces on the various piles 2. In addition, the cooled liquid which leaves in the peripheral basin 8 protects the lintel from sudden thermal variations and avoids thus the lintel cracks. It is the same, to a certain extent, for the lower part of the shell 6, the outer wall of which is heated by the cooled liquid and the vapor which still emerges therefrom. As other particular advantages, we can note:
  • - improved efficiency of the atmospheric refrigerant thanks to better air supply to the lining elements of the central area;
  • - the removal of the water outlet pipes under the atmospheric refrigerant and the central chilled water basin;
  • - the removal of the frustoconical slopes supporting the traditionally used cold water basins;
  • - the accessibility of adjustment devices, such as cofferdams;
  • - the simplification of bypass systems allowing in particular a rapid cessation of runoff during periods of intense cold;
  • - The possibility of eliminating the peripheral trays using an embodiment as shown in fig. 5;
  • - The possibility of eliminating the coolant collectors, using an embodiment as shown in fig. 6.

Tous ces éléments permettent de considérer qu'un réfrigérant selon la présente invention est d'une construction nettement plus économique que ceux existant actuellement. Il est, en outre, d'un fonctionnement plus aisé.All these elements make it possible to consider that a refrigerant according to the present invention is of a construction clearly more economical than those existing at present. It is, moreover, easier to operate.
