Abstract

The tank consists of an outer shell (10) and an inner shell (11), with the latter containing superconductors (14) which keep the inner shell situated above permanent magnets (15) on the outer shell. There is no contact between the two. The superconductors (14) have a critical temperature which lies beyond that of the liquefied gas, and are made from a hard material such as YBCO 123 or BSCCO 2212. The liquefied gas can be either LH2 or LHe, with a critical temperature above 20 degrees K.

Description

Réservoir isolant à double paroi pour le stockage de gaz liquéfié à très basse température
La présente invention concerne un réservoir isolé à double paroi pour le stockage de gaz liquéfié à très basse température d'ébullition, comprenant un réservoir extérieur et un réservoir intérieur recevant le gaz et logé à l'intérieur du réservoir extérieur.Double-walled insulating tank for storing liquefied gas at very low temperatures
The present invention relates to an insulated double-walled tank for storing liquefied gas at a very low boiling temperature, comprising an external tank and an internal tank receiving the gas and housed inside the external tank.

Les réservoirs contenant des gaz liquides à basse température d'ébullition sont toujours équipés d'une isolation coûteuse pour réduire au minimum la vaporisation du gaz liquéfié provoquée par la chaleur transmise à partir de l'environnement. Ces réservoirs sont réalisés pour cette raison sous la forme de réservoirs à double paroi, un réservoir intérieur recevant le gaz à très basse température étant placé dans un réservoir extérieur exposé à la température ambiante. Pour l'isolation, on place dans l'intervalle un matériau mauvais conducteur de chaleur, par exemple un super-isolant et après la fabrication, on réalise le vide dans l'intervalle. Tanks containing liquid gases at low boiling temperatures are always equipped with expensive insulation to minimize the vaporization of liquefied gas caused by heat transmitted from the environment. These tanks are produced for this reason in the form of double-walled tanks, an internal tank receiving the gas at very low temperature being placed in an external tank exposed to ambient temperature. For insulation, a poor heat conductive material is placed in the interval, for example a super-insulator, and after manufacture, a vacuum is created in the meantime.

Le réservoir intérieur, froid, est relié au réservoir extérieur par des moyens de suspension ou d'appui mécanique. De tels moyens de liaison sont indispensables pour transmettre le poids propre et les contraintes des efforts agissant sur le réservoir intérieur. Pour cela ces moyens doivent être suffisamment solides et rigides mécaniquement ; ils entraînent nécessairement un passage de cha leur par conduction. Cela présente un effet particulier dans le cas de réservoirs qui sont des réservoirs de véhicules pour les nouveaux carburants cryogènes, comme par exemple LH2. Pour utiliser de manière optimum le volume disponible du réservoir, il faut que, dans ce cas, l'intervalle d'isolation entre le réservoir intérieur et le réservoir extérieur soit aussi faible que possible.Dans le cas de suspensions classiques de réservoirs, cela conduit à des éléments d'appui courts avec une injection relativement importante de chaleur et par suite des durées d'utilisation, limitées. The cold internal tank is connected to the external tank by means of suspension or mechanical support. Such connecting means are essential for transmitting the self-weight and the stresses of the forces acting on the internal tank. For this these means must be sufficiently solid and mechanically rigid; they necessarily entail a passage of heat by conduction. This has a particular effect in the case of tanks which are vehicle tanks for new cryogenic fuels, such as LH2 for example. In order to make the best use of the available tank volume, in this case the insulation gap between the internal tank and the external tank must be as small as possible. In the case of conventional tank suspensions, this leads to to short support elements with a relatively large injection of heat and as a result of the limited periods of use.

La présente invention a pour but de réduire la chaleur transmise dans des réservoirs isolés à double paroi. The present invention aims to reduce the heat transmitted in insulated double wall tanks.

A cet effet, l'invention concerne un réservoir correspondant au type défini ci-dessus, caractérisé en ce que le réservoir intérieur comporte des supraconducteurs placés dans le gaz liquéfié et qui permettent de maintenir le réservoir sans contact au-dessus d'aimants permanents par rapport au réservoir extérieur. To this end, the invention relates to a reservoir corresponding to the type defined above, characterized in that the interior reservoir comprises superconductors placed in the liquefied gas and which make it possible to maintain the reservoir without contact above permanent magnets by compared to the external tank.

Suivant d'autres caractéristiques avantageuses de l'invention
- la température critique du supraconducteur dépasse la température du gaz liquéfié.According to other advantageous features of the invention
- the critical temperature of the superconductor exceeds the temperature of the liquefied gas.

- le supraconducteur est un supraconducteur dur réalisé dans les matériaux YBCO 123 ou BSCCO 2212. - the superconductor is a hard superconductor made of YBCO 123 or BSCCO 2212 materials.

- la température critique du supraconducteur est supérieure à 20"K.  - the critical temperature of the superconductor is greater than 20 "K.

- le gaz liquéfié est LH2 ou LHe. - the liquefied gas is LH2 or LHe.

Dans le réservoir selon l'invention, le réservoir intérieur est maintenu sans contact par rapport au réservoir extérieur par des aimants supraconducteurs. Du fait de cette disposition du supraconducteur dans le réservoir intérieur, le gaz liquéfié à basse température assure le rôle d'agent de refroidissement. La température du gaz à basse température d'ébullition correspond toujours à la température de travail des aimants supraconducteurs. In the tank according to the invention, the internal tank is maintained without contact with respect to the external tank by superconductive magnets. Due to this arrangement of the superconductor in the internal tank, the liquefied gas at low temperature acts as a cooling agent. The temperature of the gas at low boiling temperature always corresponds to the working temperature of the superconductive magnets.

Comme supraconducteur, on utilise les matériaux
YBCO 123 et BSCCO 0012 dont la supraconduction reste maintenue jusqu'à des champs magnétiques très importants (supraconducteur dur ou supraconducteur II). Le supraconducteur magnétique est directement en contact avec les gaz liquéfiés à très basse température d'ébullition, comme par exemple LH2 ; la température critique Tc du supraconducteur est supérieure à la température du gaz liquéfié à basse température et dépasse 200K.As a superconductor, we use the materials
YBCO 123 and BSCCO 0012 whose superconductivity remains maintained up to very large magnetic fields (hard superconductor or superconductor II). The magnetic superconductor is directly in contact with liquefied gases at very low boiling temperatures, such as LH2 for example; the critical temperature Tc of the superconductor is higher than the temperature of the liquefied gas at low temperature and exceeds 200K.

Par la disposition sans contact et néanmoins stable du réservoir intérieur dans le réservoir extérieur, on réduit considérablement la quantité totale de chaleur transmise à l'intérieur. D'autres perfectionnements de thermique résultent du fait que la super-isolation prévue dans l'intervalle peut également être réalisée sans problème au niveau du palier. By the non-contact and nevertheless stable arrangement of the internal tank in the external tank, the total amount of heat transmitted inside is considerably reduced. Other thermal improvements result from the fact that the super-insulation provided for in the interval can also be carried out without problem at the level of the bearing.

Le résultat est un temps de montée en pression et un temps d'utilisation prolongé pour des réservoirs considérablement améliorés destinés à recevoir des gaz liquéfiés à très basse température d'ébullition. The result is a pressure build-up time and an extended use time for considerably improved tanks intended to receive liquefied gases at very low boiling temperature.

Un exemple de réalisation de l'invention est représenté dans le dessin et sera décrit ci-après de manière plus détaillée. An exemplary embodiment of the invention is shown in the drawing and will be described below in more detail.

Ainsi - la figure 1 montre un réservoir isolé à double paroi avec
un montage sans contact, selon l'invention, - la figure 2 montre un premier exemple de réalisation du
dispositif de montage sans contact, selon l'invention.Thus - Figure 1 shows an insulated double-walled tank with
a contactless assembly, according to the invention, - Figure 2 shows a first embodiment of the
contactless mounting device according to the invention.

Les figures 1 et 2 montrent des réservoirs isolés à double paroi, usuels, tels que ceux utilisés pour le stockage de gaz liquéfié à très basse température tel le
LH2. Le réservoir à double paroi se compose d'un réservoir intérieur 11, d'un réservoir extérieur 10 et d'un matériau isolant placé dans l'intervalle 12 ; il s'agit par exemple d'un super-isolant. La conduite de remplissage et de prélèvement porte la référence 13. Le réservoir intérieur 11, froid, comporte des supraconducteurs 14 par exemple YBCO 123 ou BSCCO 2212 en contact direct avec le gaz liquéfié à très basse température d'ébullition. La température critique Tc du supraconducteur 14 dépasse la température du gaz liquéfié à basse température d'ébullition. En regard des supraconducteurs 14, au niveau du réservoir extérieur 10 ou d'éléments d'appui 16 fixés au réservoir extérieur 10, par exemple sur les tubes qui traversent le réservoir intérieur 11, il y a des aimants permanents 15. Le réservoir intérieur 11 est, de cette manière, maintenu en suspension sans contact par les forces de répulsion intenses et comme conséquence de la propriété pinning des supraconducteurs durs (type II) dans une position stable par rapport au réservoir extérieur 10.Figures 1 and 2 show common double wall insulated tanks, such as those used for the storage of liquefied gas at very low temperatures such as
LH2. The double-walled tank consists of an internal tank 11, an external tank 10 and an insulating material placed in the gap 12; it is for example a super-insulator. The filling and sampling line bears the reference 13. The cold internal tank 11 includes superconductors 14, for example YBCO 123 or BSCCO 2212 in direct contact with the liquefied gas at very low boiling temperature. The critical temperature Tc of the superconductor 14 exceeds the temperature of the liquefied gas at low boiling temperature. Opposite the superconductors 14, at the level of the external reservoir 10 or of support elements 16 fixed to the external reservoir 10, for example on the tubes which pass through the internal reservoir 11, there are permanent magnets 15. The internal reservoir 11 is, in this way, kept in suspension without contact by the intense repulsive forces and as a consequence of the pinning property of hard superconductors (type II) in a stable position relative to the external reservoir 10.

Comme le montre la figure 1, le supraconducteur 14 est réalisé en forme de plaque ; il est prévu sur une paroi quelconque du réservoir intérieur. Selon un autre mode de réalisation, on a plusieurs supraconducteurs 14 en forme de tige fixés de part et d'autre d'un tube 16 qui traverse le réservoir intérieur 11, et entre lesquels sont montés des aimants permanents.  As shown in Figure 1, the superconductor 14 is made in the form of a plate; it is provided on any wall of the interior tank. According to another embodiment, there are several rod-shaped superconductors 14 fixed on either side of a tube 16 which passes through the internal reservoir 11, and between which permanent magnets are mounted.
