Title
(EN) LIQUID HELIUM RECONDENSATION DEVICE AND TRANSFER LINE USED THEREFOR
(FR) APPAREIL PERMETTANT DE RECONDENSER DE L'HELIUM LIQUIDE ET CONDUITE DE TRANSFERT UTILISEE A CET EFFET
Abstract
(EN)
A liquid helium recondensation device which includes a liquid helium storage tank (1) and a refrigerating machine (5) that recovers the helium gas vaporized in the storage tank and cools and liquefies the helium gas, and which can return the cooled helium gas cooled by or the liquid helium liquefied by the refrigerating machine to the storage tank, the device comprising a line (9c) whereby the high temperature helium gas elevated in temperature in the liquid helium storage tank is fed to the refrigerating machine and the cooled helium gas from the latter is then fed to the upper region in the storage tank, and lines (9b, 9a) whereby the low temperature helium gas in the vicinity of the liquid level of the liquid helium in the liquid helium storage tank is fed to the refrigerating machine for liquefying and the liquid helium from the latter is fed to the storage tank.
(FR)
Cet appareil permettant de recondenser de l'hélium liquide comporte une cuve de stockage d'hélium liquide (1) et un appareil de réfrigération (5) récupérant l'hélium en phase gazeuse vaporisé dans la cuve de stockage et le refroidissant, puis le liquéfiant. Cet hélium en phase gazeuse refroidi ou liquéfié par l'appareil de réfrigération est ensuite ramené dans la cuve de stockage. L'appareil comportene conduite (9c) au moyen de laquelle l'hélium en phase gazeuse à haute température, monté en température dans la cuve de stockage d'hélium liquide, est transféré dans l'appareil de réfrigération. L'hélium en phase gazeuse provenant de cet appareil de réfrigération est ensuite transféré dans la partie supérieure de la cuve de stockage. L'appareil comporte également des conduites (9b, 9a) servant à transférer l'hélium en phase gazeuse à basse température se trouvant à proximité, dans la cuve, de l'hélium liquide, vers l'appareil de réfrigération et ce, afin de le liquéfier. L'hélium liquéfié est ensuite transféré dans la cuve de stockage.
