Abstract
The utility model discloses a liquefied natural gas storage tank. The liquefied natural gas storage tank comprises a liner, a housing and a supporting assembly, wherein a supporting rod is arranged at the tail end of the liner; the supporting assembly is arranged at the tail part in the housing; the supporting rod is inserted in the supporting assembly; an insulation cover made from a thermal insulation material is arranged on a contact site between the supporting rod and the supporting assembly. The liquefied natural gas storage tank can avoid the phenomenon that the natural gas in the liner is quickly gasified as the external heat enters the liner, improves the thermal insulation performance between the liner and the housing, finally ensures that the temperature of the inside liquefied natural gas cannot be raised, and improves the gas storage capacity of the storage tank.
Description
Technical field
The utility model relates to a kind of liquefied natural gas (LNG) tank.
Background technique
At present, the supporting element of former inner bag before this by supporting component directly and shell interconnect, to such an extent as to the heat of shell is directly delivered to inner bag inside, make internal liquid Quick-gasifying, inner pressure also will increase gradually, the time that maintains safety valve unlatching also will shorten, and a large amount of natural gas gasifyings is discharged in atmosphere so that causes potential safety hazard and waste situation.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, a kind of liquefied natural gas (LNG) tank is provided, it can avoid outside heat to enter inner bag, and make the rock gas of inner bag inside by the phenomenon of Quick-gasifying, thereby improve the heat-insulating capability between inner bag and shell, the inner LNG Liquefied natural gas temperature of final long-time interior guarantee does not raise, and improves the gas storage capability of storage tank.
The utility model solves the problems of the technologies described above the technological scheme of taking: a kind of liquefied natural gas (LNG) tank, it comprises inner bag, shell and supporting component, the tail end of inner bag has support stick, supporting component setting afterbody in the enclosure, described support stick is inserted in supporting component, between described support stick and the contact position of supporting component, is provided with the collet of being made up of thermoinsulation material.
Further, described supporting component comprises dunnage and supporting sleeve, and the two ends of dunnage are fixedly connected with afterbody in the enclosure, and described supporting sleeve is fixed on the middle part of dunnage, and described collet is arranged between support stick and supporting sleeve.
Further, the tail end of described inner bag is liner end enclosure, and the afterbody of described shell is shell end socket, and described support stick is arranged on liner end enclosure, and described supporting component is arranged on the inwall of shell end socket.
Further, described support stick and supporting component are made by stainless steel material.
Further, described collet is resistance to 300 DEG C of collets.
Adopt after technique scheme, the utility model is provided with collet between support stick and supporting component, and collet is made up of thermoinsulation material, this structure has directly been cut off heat transfer path, to avoid outside heat to enter inner bag, and make the rock gas of inner bag inside by the phenomenon of Quick-gasifying, thereby improved the heat-insulating capability between inner bag and shell, the inner LNG Liquefied natural gas temperature of final long-time interior guarantee does not raise, and has improved the gas storage capability of storage tank.
Brief description of the drawings
