Fig. 1 shows a kind of structure of existing low-temperature multilayer heat insulating vessel 10.Container 10 has the telescopic container wall that is made of inner and outer wall, and wherein, inwall comprises columniform inner barrel 11 and is positioned at the end socket 12 at inner barrel 11 two ends; Outer wall is enclosed in inner wall outside, and comprises columniform outer cylinder body 13 and the outside head 14 that is positioned at outer cylinder body 13 two ends.Inner barrel 11 and outer cylinder body 13 have consisted of the shell portion of container 10, and interior end socket 12 and outside head 14 have consisted of the end socket part of container 10.The inner container that is formed by inwall is used for loading cryogenic media.Interlayer 15 between the inside and outside wall is configured to vacuum, thus improve container heat-insulating property, reduce cryogenic media in the container to the race cold of normal temperature environment." vacuum " in this specification refers to that air pressure wherein is less than or equal to 0.01Pa.
In order further to improve the heat-insulating property of container 10, be provided with multilayer insulant at the outer surface of container inner wall.Insulation material layer is arranged in interlayer 15.As time goes on, insulation material layer may discharge gas, reduces the degree of vacuum of interlayer 15, thereby reduces the heat-insulating property of container.For this reason, in container 10, usually also be provided with one or more cryogenic absorption devices 16.
As shown in Figure 2, cryogenic absorption device 16 comprises: the cover body 161 that end sealing, an end open wide, and the baffle plate 162 that is installed in the open end of cover body 161.The low temperature adsorbent 90 of adsorbable gas is filled in the space between cover body 161 and the baffle plate 162.Baffle plate 162 is provided with the hole, and is provided with screen net structure 164 in the inboard of baffle plate 162, is used for preventing that low temperature adsorbent 90 from spilling from the hole of baffle plate 162.Because low temperature adsorbent adsorption performance at low temperatures is good, thereby the cryogenic absorption device is arranged on the low temperature side of container usually, namely is fixed on the inwall, and protrudes towards internal tank.For example, be fixed to as shown in Figure 1 on the inner barrel 11.Have the hole for the corresponding region of fixing this cryogenic absorption device 16 on the inner barrel 11, like this, the gas in the interlayer 15 just can enter cryogenic absorption device 16 and be adsorbed by low temperature adsorbent 90 via the hole on the hole on the inwall and the baffle plate 162.
