Description

La présente invention concerne un réservoir de fluide cryogénique et un procédé de remplissage et/ou de soutirage. L'invention concerne plus particulièrement un réservoir de fluide cryogénique comprenant une enveloppe délimitant un volume de stockage muni d'une ouverture, le réservoir comprenant une buse reliée à l'ouverture de l'enveloppe pour injecter et éventuellement soutirer du fluide dans l'enveloppe, la buse comprenant une conduite pour véhiculer du fluide s'étendant au travers de l'ouverture et débouchant dans l'enveloppe.3 A l'équilibre un réservoir cryogénique contient un fluide (par exemple un 10 gaz) à une température uniforme. Généralement, la température de l'enveloppe du réservoir qui délimite le volume de stockage est à une température proche ou identique à celle du fluide stocké. Dans le cas par exemple où ce réservoir reçoit lors d'un remplissage un volume de fluide à une température différente (notamment du gaz plus froid ou 15 plus chaud), un différentiel de température important peut exister entre le dispositif d'injection et le réservoir. Ce différentiel de température peut créer des contraintes thermomécaniques importantes au niveau de certaines parties du réservoir (notamment au niveau de son col d'entrée auquel est soudée la buse d'injection de gaz). 20 Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. A cette fin, le réservoir selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que la conduite est reliée à l'ouverture via un organe de fixation interposé entre 25 l'enveloppe et la conduite et en ce que la conduite est espacée de l'enveloppe. Une telle géométrie de buse permet remplir un réservoir avec un fluide ayant une température très différente de la température du réservoir, sans provoquer des contraintes thermiques et mécaniques néfastes pour la tenue du réservoir. 30 Par ailleurs, des modes de réalisation de l'invention peuvent comporter l'une ou plusieurs des caractéristiques suivantes : - l'ouverture de l'enveloppe est délimitée par un col, l'organe de fixation étant fixé audit col, - la conduite est espacée de l'enveloppe d'une distance comprise entre 100 mm et la moitié de la longueur du réservoir et de préférence comprise entre 100 mm et 500 mm, - l'organe de fixation comprend une bride traversée par la conduite et fixée audit col, - l'organe de fixation est fixé à l'ouverture de l'enveloppe par l'un au moins parmi : un soudage, un rivetage, un vissage, un boulonnage, un système dit « clamp », un encliquetage, - l'enveloppe est composée de l'un au moins des matériaux suivant : un acier, un alliage métallique, de l'aluminium, un acier inoxydable austénitique, un acier allié au nickel, - la conduite est composée de l'un au moins des matériaux suivant : un acier, un alliage métallique, de l'aluminium, un acier inoxydable austénitique, un acier allié au nickel, - l'organe de fixation est composé de l'un au moins des matériaux suivant : un acier, un alliage métallique, de l'aluminium, un plastique, un matériau composite un acier inoxydable austénitique, un acier allié au nickel, - la zone de l'enveloppe délimitant l'ouverture comprend un rebord plan concentrique à l'ouverture, l'organe de fixation est fixé à ce rebord, - le différentiel de température entre d'une part, la température de l'enveloppe et, d'autre part, la conduite est comprise entre 0 K et 300 K et de préférence comprise entre 100 K et 300 K, - l'enveloppe est entourée d'une paroi extérieure, un vide étant ménagé entre l'enveloppe et la paroi extérieure, c'est-à-dire que le réservoir est à double enveloppe isolées sous vide. L'invention concerne également un procédé de remplissage et/ou de soutirage d'un réservoir de fluide avec un fluide, le réservoir comprenant une enveloppe délimitant un volume de stockage muni d'une ouverture, le procédé utilisant une buse reliée à l'ouverture de l'enveloppe pour injecter et/ou soutirer du fluide dans l'enveloppe, la buse comprenant une conduite pour véhiculer du fluide s'étendant au travers de l'ouverture et débouchant dans l'enveloppe, la conduite étant maintenue espacée de l'enveloppe et via un organe de fixation interposé entre l'enveloppe et la conduite.The present invention relates to a cryogenic fluid reservoir and a method of filling and / or withdrawal. The invention more particularly relates to a cryogenic fluid reservoir comprising an envelope defining a storage volume provided with an opening, the reservoir comprising a nozzle connected to the opening of the casing for injecting and possibly drawing fluid into the casing. the nozzle comprising a conduit for conveying fluid extending through the opening and opening into the casing. At equilibrium a cryogenic reservoir contains a fluid (eg a gas) at a uniform temperature. Generally, the temperature of the tank shell which delimits the storage volume is at a temperature close to or identical to that of the stored fluid. In the case, for example, where this reservoir receives during a filling a volume of fluid at a different temperature (in particular colder or hotter gas), a significant temperature difference may exist between the injection device and the reservoir. . This temperature differential can create significant thermomechanical stresses at certain parts of the tank (particularly at its inlet neck which is welded to the gas injection nozzle). An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above. For this purpose, the tank according to the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the pipe is connected to the opening via a fastener interposed between 25 the envelope and the pipe and in that the pipe is spaced from the envelope. Such a nozzle geometry makes it possible to fill a reservoir with a fluid having a temperature that is very different from the temperature of the reservoir, without causing adverse thermal and mechanical stresses for the holding of the reservoir. Furthermore, embodiments of the invention may comprise one or more of the following features: the opening of the envelope is delimited by a collar, the fastener being fixed to said neck; is spaced from the casing by a distance of between 100 mm and half the length of the tank and preferably between 100 mm and 500 mm, the fastening member comprises a flange through which the pipe passes and fixed to said neck. the fixing member is fixed to the opening of the casing by at least one of: welding, riveting, screwing, bolting, a so-called "clamp" system, a snap-fastening, envelope is composed of at least one of the following materials: a steel, a metal alloy, aluminum, austenitic stainless steel, a nickel-alloy steel, - the pipe is composed of at least one of the following materials : a steel, a metal alloy, aluminum, a stainless steel austenitic ble, a nickel-alloy steel, - the fixing member is composed of at least one of the following materials: a steel, a metal alloy, aluminum, a plastic, a composite material an austenitic stainless steel, a nickel-alloy steel, - the zone of the envelope delimiting the opening comprises a planar flange concentric with the opening, the fixing member is fixed to this rim, - the temperature differential between, on the one hand, the temperature of the envelope and, on the other hand, the pipe is between 0 K and 300 K and preferably between 100 K and 300 K, - the casing is surrounded by an outer wall, a vacuum being provided between the shell and the outer wall, that is to say that the tank is vacuum-insulated double jacket. The invention also relates to a method for filling and / or withdrawing a fluid reservoir with a fluid, the reservoir comprising an envelope defining a storage volume provided with an opening, the method using a nozzle connected to the opening the casing for injecting and / or withdrawing fluid from the casing, the nozzle comprising a conduit for conveying fluid extending through the aperture and opening into the casing, the duct being kept spaced from the casing envelope and via a fastener interposed between the envelope and the pipe.

Selon d'autres particularités possibles : - le réservoir et notamment l'enveloppe est à une température d'équilibre comprise entre 4 K et 300 K et de préférence comprise entre 4 K et 100 K, du fluide étant injecté via la conduite dans le réservoir à une température comprise entre 4 K et 300 K et de préférence comprise entre 4 K et 80 K ou entre 200K et 300K. L'invention peut concerner également tout dispositif ou procédé alternatif comprenant toute combinaison des caractéristiques ci-dessus ou ci-dessous.

Le réservoir de fluide cryogénique illustré à titre d'exemple non limitatif à la figure comprend une enveloppe 2, par exemple de formé générale cylindrique, délimitant un volume de stockage. Une extrémité de l'enveloppe 2 est munie d'une ouverture 3, de préférence délimité par un col 6. L'enveloppe 2 peut être constituée, par exemple, de l'un au moins des matériaux suivant : un acier, un alliage métallique, de l'aluminium, notamment un acier inoxydable austénitique, un acier allié au nickel.According to other possible particularities: the reservoir and in particular the envelope is at an equilibrium temperature of between 4 K and 300 K and preferably between 4 K and 100 K, the fluid being injected via the pipe into the reservoir at a temperature between 4 K and 300 K and preferably between 4 K and 80 K or between 200K and 300K. The invention may also relate to any alternative device or method comprising any combination of the above or below features. Other features and advantages will appear on reading the description below, with reference to the single figure which shows a sectional view, schematic and partial, illustrating an exemplary embodiment of implementation of the invention. The cryogenic fluid reservoir illustrated by way of non-limiting example in the figure comprises an envelope 2, for example of cylindrical general shape, delimiting a storage volume. One end of the casing 2 is provided with an opening 3, preferably delimited by a neck 6. The casing 2 may consist, for example, of at least one of the following materials: a steel, a metal alloy , aluminum, especially austenitic stainless steel, a nickel-alloy steel.

De même, cette enveloppe 2 peut être l'enveloppe interne d'un réservoir cryogénique à double enveloppe et isolée sous vide. C'est-à-dire que l'enveloppe 2 peut être entourée d'une enveloppe externe (non représentée par soucis de simplification) et un vide d'air peut être ménagé entre ces deux enveloppes interne et externe.Likewise, this envelope 2 may be the internal envelope of a cryogenic tank with double jacket and vacuum insulated. That is to say that the envelope 2 may be surrounded by an outer envelope (not shown for the sake of simplification) and an air gap may be provided between these two inner and outer shells.

Le réservoir 1 comprend une buse 4 reliée à l'ouverture 3 de l'enveloppe pour injecter et éventuellement soutirer du fluide dans l'enveloppe 2 et notamment du gaz. La buse 4 comprenant une conduite 5, par exemple tubulaire, pour véhiculer du fluide. La conduite 5 s'étend au travers de l'ouverture 3 et débouche dans l'enveloppe 2. La conduite 5 peut être constituée de l'un au moins des matériaux suivant : un acier, un alliage métallique, de l'aluminium, notamment un acier inoxydable austénitique ou un acier allié au nickel.The reservoir 1 comprises a nozzle 4 connected to the opening 3 of the casing for injecting and possibly drawing fluid into the casing 2 and in particular gas. The nozzle 4 comprising a pipe 5, for example tubular, for conveying fluid. The pipe 5 extends through the opening 3 and opens into the casing 2. The pipe 5 may consist of at least one of the following materials: a steel, a metal alloy, aluminum, in particular austenitic stainless steel or nickel-alloy steel.

Selon une particularité avantageuse, la conduite 5 est reliée à l'ouverture via un organe 6 de fixation interposé entre l'enveloppe 2 et la conduite 5. La conduite 5 est espacée de l'enveloppe 2. C'est-à-dire que la conduite 5 qui véhicule le fluide potentiellement plus froid ou plus chaud n'est pas en contact direct avec l'enveloppe 2 ni soudée sur cette dernière et notamment sur son col 6. De cette façon, l'enveloppe 2 du réservoir 1 est isolée de la conduite 5 et il n'y a pas de point de contact soumis à une contrainte thermique trop importante. De plus, cette architecture permet des dilatations/rétractations différentielles de la conduite 5 et du réservoir sans générer des efforts néfastes. Le matériau constitutif de la conduite 5 et de l'organe 6 de fixation peut être différent de celui constituant l'enveloppe 2. Ceci fournit un degré de flexibilité supplémentaire. De préférence la conduite 5 est espacée de l'enveloppe 2 d'une distance comprise entre 100 mm et la moitié de la longueur du réservoir et de préférence comprise entre 200 mm et 500 mm. Un espacement compris entre la conduite 5 et 15 l'enveloppe 2 compris entre 20mm et 50mm est également envisageable. Par exemple, le col 8 a un diamètre intérieur compris entre 100 mm et 1000 mm tandis que le diamètre extérieur de la conduite 5 est compris entre 50 mm et 900 mm. L'organe 6 de fixation peut comprendre une bride, par exemple plane, traversée et fixée à la conduite 5. La bride 6 est fixée au col 6, par exemple sur 20 une collerette 7 formant un rebord à une extrémité du col 6. La bride 6 est par exemple soudée ou fixée par tout autre moyen approprié sur le col 6 de l'enveloppe 2. La buse 4 ou le réservoir 1 muni de la buse 4 peuvent être utilisés pour des stockages de fluides cryogénique par exemple des gaz, liquides ou mélanges 25 diphasiques (liquide/gaz) comprenant notamment l'un parmi : de l'hélium, de l'azote, de l'hydrogène du dioxyde de carbone, de l'hydrogène, ... Le réservoir peut tolérer des remplissages avec du gaz présentant un différentiel de températures par rapport à la température de l'enveloppe 2 compris entre 0 et 300K. 30According to an advantageous feature, the pipe 5 is connected to the opening via a fastener 6 interposed between the casing 2 and the pipe 5. The pipe 5 is spaced from the casing 2. That is to say that the pipe 5 which conveys the potentially colder or hotter fluid is not in direct contact with the shell 2 nor welded to the latter and in particular on its neck 6. In this way, the shell 2 of the tank 1 is isolated of the pipe 5 and there is no contact point subjected to excessive thermal stress. In addition, this architecture allows differential expansion / retraction of the pipe 5 and the reservoir without generating harmful efforts. The constituent material of the pipe 5 and the fixing member 6 may be different from that constituting the casing 2. This provides an additional degree of flexibility. Preferably the pipe 5 is spaced from the casing 2 by a distance of between 100 mm and half the length of the tank and preferably between 200 mm and 500 mm. A spacing between the pipe 5 and the casing 2 between 20mm and 50mm is also possible. For example, the neck 8 has an inside diameter of between 100 mm and 1000 mm while the outside diameter of the pipe 5 is between 50 mm and 900 mm. The fixing member 6 may comprise a flange, for example flat, crossed and fixed to the pipe 5. The flange 6 is fixed to the neck 6, for example on a flange 7 forming a flange at one end of the neck 6. The flange 6 is for example welded or fixed by any other appropriate means on the neck 6 of the casing 2. The nozzle 4 or the tank 1 provided with the nozzle 4 can be used for storing cryogenic fluids, for example gases, liquids or two-phase mixtures (liquid / gas) comprising in particular one of: helium, nitrogen, hydrogen, carbon dioxide, hydrogen, etc. The reservoir can tolerate fills with gas having a temperature differential with respect to the temperature of the casing 2 between 0 and 300K. 30
