Abstract
The utility model discloses a high-vacuum cryogenic storage tank, which comprises an outer cylinder and an inner cylinder. A jacket is arranged between the outer cylinder and the inner cylinder. A first adsorption container for filling adsorbent is arranged at the bottom of the jacket. A second adsorption container for filling the adsorbent is arranged at the bottom of the jacket. The opening of the second adsorption container is guided to the top of the jacket through a guide pipe. According to the high-vacuum cryogenic storage tank disclosed by the utility model, because the second adsorption container is arranged at the bottom of the jacket and the opening of the second adsorption container is guided to the top of the jacket through the guide pipe, gas with lower relative density can be directly adsorbed; and the second adsorption container installed at the bottom of the jacket still has low-temperature adsorption effect.
Description
Technical field
The utility model relates to a kind of liquid-container, relates in particular to a kind of storage tank that is used to hold cryogenic liquid.
Background technique
The deep cooling storage tank is the deep cooling container that is used to deposit products such as LNG Liquefied natural gas, liquid oxygen, liquid nitrogen, liquid argon.The deep cooling storage tank generally is made up of urceolus and inner core, and the chuck between urceolus and the inner core is filled with thermoinsulation material, and the chuck vacuum requirements of high vacuum cryogenic storage tank is≤5 * 10
-2Pa.
In order to adsorb residual gas in the chuck, generally be provided with contactor, sorbent (for example molecular sieve etc.) is housed in contactor.Because contactor has opening down, come off in order to prevent sorbent, be provided with isolation net at the opening of contactor, can prevent that granular sorbent from coming off.
After deep cooling storage tank inner core took up cryogenic liquide, bottom temp was relatively low, so contactor generally all is located at chuck bottom, helped giving full play to the cryogenic absorption effect of sorbent.But the deep cooling tank top that volume is bigger is far away apart from the bottom, and the residual gas that in the higher environment of degree of vacuum, is in the chuck top is the less relatively gas contactor that is in the chuck bottom more difficult to get access of density especially.
The model utility content
The utility model provides a kind of degree of vacuum high, to the high vacuum cryogenic storage tank of residual gas advantages of good adsorption effect.
A kind of high vacuum cryogenic storage tank; Comprise urceolus and inner core; Be chuck between urceolus and the inner core, the bottom of chuck is provided with first contactor of loading sorbent, it is characterized in that; The bottom of chuck is provided with second contactor of loading sorbent, and the opening of described second contactor is guided the top of chuck into through conduit.
The opening that described conduit is positioned at the chuck top is provided with isolation net.
Described first contactor has opening down, comes off in order to prevent sorbent, is provided with isolation net at the opening of first contactor.
The outer wall of tube bottom in described first contactor and second contactor are installed in.
The both sides that are distributed in the inner core axis of described first contactor and second contactor symmetry.
The utility model high vacuum cryogenic storage tank is provided with second contactor in the bottom of chuck; The opening of second contactor is guided the top of chuck into through conduit; Can directly adsorb, and second contactor is installed in the adsorption effect that low temperature still can be brought into play in the bottom of chuck to the less relatively gas of density.
Description of drawings
Fig. 1 is the structural representation of a kind of high vacuum cryogenic storage tank of the utility model.
Embodiment
Referring to accompanying drawing; A kind of high vacuum cryogenic storage tank of the utility model comprises urceolus 1 and inner core 2, is chuck 3 between urceolus 1 and the inner core 2; The bottom of chuck 3 is provided with first contactor 5 of loading sorbent; First contactor 5 has opening down, comes off in order to prevent sorbent, is provided with isolation net 4 at the opening of first contactor 5.
The bottom of chuck 3 is provided with second contactor, 6, the first contactors 5 of filling sorbent and the outer wall that second contactor 6 is installed in interior tube bottom, and the both sides that are distributed in the inner core axis of symmetry.
The opening of second contactor 6 is guided the top of chuck 3 into through conduit 7, and the opening that conduit 7 is positioned at chuck 3 tops is provided with isolation net 8.
The utility model high vacuum cryogenic storage tank is provided with second contactor in the bottom of chuck; The opening of second contactor is guided the top of chuck into through conduit; Can directly adsorb, and second contactor is installed in the adsorption effect that low temperature still can be brought into play in the bottom of chuck to the less relatively gas of density.
