CRYOGENIC RESERVOIR AND METHOD OF REMOVAL OF HYDROGEN FROM ITS VACUUM CHAMBER Russian patent published in 1994 - IPC

FIELD: cryogenic engineering. SUBSTANCE: cryogenic reservoir has casing inside which heat-insulated inner vessel is arranged forming heat-insulated chamber, cartridge with filter and chemical absorbent secured on the casing; cartridge is provided with heat accumulator and is made in form of flat disk located horizontally in upper portion of the reservoir; detachable heater is made in form of beam-receiving panel consisting of at least three plates arranged in spaced relation to one another; lower plate adjoins outer surface of the cartridge and is provided with selective absorbing coating. Removal of hydrogen from heat-insulated chamber of hydrogenic reservoir is effected through chemical reaction of hydrogen evolved by inner walls of reservoir with absorbent on base of metal oxides and intermetallic dispersed catalyst; before placing reservoir in operation, absorbent is activated through heating it, after activation, heating is discontinued and activation of absorbent is effected by sun radiation of the cartridge; after activation, outer casing of reservoir is heated by flux of sun radiation in daytime by covering the outer surface of reservoir with detachable sectionalized beam-receiving coat made in form of at three flexible films arranged in a spaced relation to one another; lower layer is provided with selective absorbing coating at high absorption factor which is made of heat-resistant film; two other layers are translucent. Prior to placing the reservoir in operation, the coat is taken off the casing and temperature is restored to magnitudes corresponding to operating temperature. EFFECT: enhanced efficiency. 3 cl, 3 dwg
