Embodiment 1
[0011] Embodiment 1, a dry adsorption device for a cryogenic container, is characterized in that: a cylindrical adsorption chamber housing 5 with a sealing head 6 at one end and a blocking plate 3 at the other end is fixed on the inner liner 7 wall, One end of the head is located inside the inner tank, and the end with the blocking plate is located in the interlayer space 8 between the inner tank and the outer shell 9. The housing is equipped with a molecular sieve 1, and the blocking plate is equipped with a nitrogen filling pipe 4 passing through the outer shell. The plate is provided with gas exchange ports 2 covered with a sealing plate.
[0012] The sealing plate is a 0.05mm copper plate.
[0013] The method for using a dry adsorption device for a cryogenic container is characterized in that: after the cryogenic container is assembled, when the interlayer space between the liner and the shell is evacuated, a nitrogen-filled tube is used to evacuate the adsorption chamber ...

The invention discloses a drying and adsorption device for a cryogenic container, belongs to containers which are used for containing or storing condensed, liquefied, or solidified gas, and in particular to parts of the containers. The drying and adsorption device for the cryogenic container is characterized in that an adsorption chamber shell is fixed on the wall of a liner, an end socket is installed at one end of the adsorption chamber shell and a blocking board is arranged at the other end of the adsorption chamber shell, the end which is provided with the end socket is located inside the liner, the end which is provided with the blocking board is located inside a interlayer space between the liner and a housing, a molecular sieve is installed inside the shell, a nitrogen blanketing tube which is through the housing is arranged on the blocking board, a gas exchange mouth is formed in the blocking board, and a sealing board is covered on the gas exchange mouth. The drying and adsorption device for the cryogenic container has the advantages that one part of an adsorption chamber of drying and adsorption device for the cryogenic container is located inside the liner, the problem that the adsorption chamber can not be installed because the interlayer space is small is resolved, at the same time, the adsorption chamber directly contacts with liner medium, and the lower the temperature is, the better the adsorption effect is. An open pore which is used when the adsorption chamber is installed can be used as a process manhole during the process of manufacturing.
Description
technical field [0001] The invention belongs to containers for holding or storing compressed, liquefied or solidified gas, especially the parts of the containers. Background technique [0002] The interlayer of cryogenic containers such as liquefied natural gas storage and transportation tanks needs to be in a vacuum state. To achieve vacuum, long-term pumping is used to achieve high vacuum. However, the filler in the interlayer and equipment manufacturing materials will still emit a small amount of gas or moisture. In order to maintain the interlayer To keep the vacuum for a long time, molecular sieves are often used as adsorption materials. The applicant’s prior patent CN201363549 discloses "An Adsorption Chamber for Dry Packing" which better solves the problem of adsorption of residual gas in the interlayer of cryogenic containers, but the adsorption chamber is completely installed in the interlayer between the inner tank and the outer shell , only applicable to the case...
