Description

The storage tank of the liner end enclosure structure of tank for liquefied gas and the described structure of employing
Technical field
The utility model relates to a kind of liquefied gas at low temp warehousing and transportation facilities, more particularly relate to a kind of high-vacuum insulation liquefied gas at low temp storage tank that is used for the liner end enclosure structure of high-vacuum insulation liquefied gas at low temp storage tank and has adopted described liner end enclosure structure.The combination supporting structure of the little gap high-vacuum insulation of the utility model by possessing superior impact resistance and heat-insulating capability, realized that impact force and acknowledgement of consignment medium temperature that the liquefied gas at low temp warehousing and transportation facilities bears change the requirement of satisfying the liquefied gas at low temp accumulating in running, and the vacuum layer between low-temperature (low temperature) vessel inner bag and the urceolus is the thinnest, finally realizes the charging ratio maximum of liquefied gas at low temp.The utility model belongs to cryogenic engineering and cryogenic technique field.
Background technique
The vacuum of being born in 1909-powder isolation technology makes the performance of low-temperature storage tank be greatly improved.To the end of the thirties in last century, it is the whole low temperature field of representative that vacuum-powder isolation has been widely used in air separation and liquefaction.At the beginning of the fifties in last century, high vacuum multiple layer heat insulation has occurred, it is the historical important development of Cryo Heat Insulation, particularly in the latter stage fifties, because the development of space technology, the consumption surge of liquid hydrogen, liquid helium has promoted the research and the application of high vacuum multiple layer heat insulation greatly, wherein, the tank car of transfer of cryogenic liquid gas and tank container are exactly main application product.
In the cryogenic technique field, liquefied gas at low temp refers to the gas that exists with liquid form below-160 ℃, for example liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, liquid methane and LNG etc.Because the liquid volume ratio gaseous state of this class gas dwindles about 600 times, therefore often with the mode accumulating of liquid state.The equipment of transfer of cryogenic liquid gas, comprise tank car and jar case etc., tank body is a double layer construction, be vacuum layer between inner bag and the shell, inner bag is connected by supporting structure with shell, because the requirement of transport law, warehousing and transportation facilities (tank car and jar case etc.) all has maximum boundary dimension restriction, under the situation that has limited maximum boundary dimension, the actual volume of the medium that warehousing and transportation facilities (tank car and jar case etc.) can load and transport just depends on the thickness of vacuum layer.
A vacuum-powder isolation tank car and a jar case are present domestic comparatively general low temperature haulage devices, be by the vacuum layer between shell and inner bag add perlite wait realize heat insulation, in order to reach satisfied effect of heat insulation, vacuum layer is comparatively thick, usually vacuum layer thickness is at 200 ~ 300 millimeters, therefore, the actual volume of actual shipment goods has just been sacrificed; Add the deposition of perlite in transportation process, the heat-shielding performance of haulage device is affected.So the application of high vacuum multiple layer heat insulation technology in haulage device promoted.Model utility ZL00216678.X, ZL00249960.6, ZL01272605.2 are exactly the application case of high vacuum multiple layer heat insulation technology in haulage device.
High vacuum multiple layer heat insulation warehousing and transportation facilities (tank car and jar case etc.) is the outer surface winding thermal-protective material at the tank body inner bag, and by the vacuum sandwich pumping high vacuum that comprises multilayer insulation material is formed heat insulation layer, vacuum sandwich is thin more, and it is many more that tank body loads conveying medium; But heat insulation layer is thin more, the difficult more layout of supporting structure that connects inner bag and shell, heat insulation layer is thin more, condition of high vacuum degree is low more, and the heat transfer of inner bag and shell is many more, and the heat loss of liquefied gas at low temp is big more, present multilayer heat insulation technology, in ZL00249960.6 and ZL01272605.2, consider the layout of radial support in the vacuum layer, the vacuum layer thickness between shell and the inner bag is also had in 100 millimeter.The inner supporting structure of inner bag and shell should bear because the power that liquid load, storage tank weight and respective impact acceleration are produced, also must reduce the caused leaking heat of inner supporting structure as far as possible, so inner supporting structure is the key of low-temperature storage tank design.In the existing technology, both at home and abroad at present on the low-temperature storage tank that adopts there be inner supporting structure: 1) the mat insulation block structure between inner bag and shell, play the expand with heat and contract with cold problem of caused high vacuum multiple layer heat insulation damage layer or interruption of the big problem of supporting leaking heat and inner barrel but can not effectively solve high vacuum multiple layer heat insulation spacing introductory note; 2) stainless steel sleeve tubular construction between inside and outside end socket, it is poor that the spacing of making difficulty, inside and outside end socket reaches impact resistance greatly, and leaking heat is bigger; 3) hang the drawstring structure, the impact resistance decline problem that can not effectively solve expands with heat and contract with cold causes; 4) the low-temperature (low temperature) vessel resisting strong impact supporting structure of model utility ZL00216678.X, contact gap increases when requiring the end socket spacing to reach normal temperature greatly to change low temperature over to, and the shock resistance level reduces.
Along with the development of China's liquefied gas at low temp can-type storage, in the dimensional range that limits, how to increase the storage volumes of liquefied gas at low temp effectively and improve heat insulation and the shock resistance level, be the target that artificers pursue.The utility model has overcome the deficiency that existing support design exists, and has used new liner end enclosure structure, so that characteristics such as storage tank has that thermal-protective coating is thin, heat-shielding performance is superior and the liquid storage volume is big.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of new liner end enclosure structure that is used for high-vacuum insulation liquefied gas at low temp storage tank.
