Abstract
The utility model relates to a low-temperature spherical tank anti-shrinkage heat isolation pillar which comprises an inner shell and an outer shell of the spherical tank, an upper section of pillar and a lower section of pillar; the upper end of the upper section of the pillar is fixedly connected with the inner shell, and the lower end of the upper section of pillar is fixedly connected with an upper connecting plate; the upper end of the lower section of pillar is fixedly connected with a lower connecting plate; a heat isolation layer is arranged between the upper connecting plate and the lower connection plate and is connected with the upper connecting plate and the lower connection plate through bolts; and bolt holes on the upper connecting plate, the lower connecting plate and the heat isolation layer are long circular holes towards the center of sphere of the spherical tank. According to the low-temperature spherical tank anti-shrinkage heat isolation pillar, not only is the approach that an inner tank leaks heat through the pillar blocked effectively but also the transmission of cold energy of an inner container to a foundation is blocked, and meanwhile due to the design of the displacement structures of the long circular holes which are towards the center of sphere, the cold shrinkage of the inner tank which is produced at low temperature can be effectively absorbed.
Description
Technical field
The utility model relates to a kind of low temperature spherical tank, is specifically related to the adiabatic pillar of anti-shrinkage of a kind of bivalve low temperature spherical tank.
Background technique
The Cryo Heat Insulation pressurized container that is used for storing liquid hydro carbons, liquified natural gas, liquid oxygen, liquid argon and liquid nitrogen at present is single jar that holds of vertical and cylindrical basically, the bottom of inner container is dropped on the thermal-protective coating fully, entire equipment basis is elevated structure or the basis of landing of adopting pre-buried heating system, to prevent the freezing basis of cold owing to medium, and then influence storage tank safety, the storage tank of this structure has the foundation cost height, day relative evaporation is many, shortcomings such as equipment manufacturing cost height, regular maintenance expense height.The Cryo Heat Insulation pressurized container of the cryogenic media of the employing spherical storage tank of research and development storage has in recent years solved above deficiency, and utilize spherical storage tank to store cryogenic media and also have plurality of advantages, its using scope is more and more wider, but the interior shore supports structure of former use is carried out heat in the supporting structure bottom and is cut off, this simple in structure, but leaking heat is very big, has aggravated the day evaporation loss of storage tank, increased the regular job maintenance cost of storage tank, the cold contraction deformation of jar in also can't absorbing simultaneously.
The model utility content
The utility model provides the anti-shrinkage of a kind of low temperature spherical tank adiabatic pillar, can absorb the cold contraction deformation of interior jar of spherical tank, effectively reduces leakage heat, the storage low temperature liquid medium of safety and nondestructive simultaneously.
For this reason, the technological scheme that adopts of the utility model is:
The adiabatic pillar of the anti-shrinkage of a kind of low temperature spherical tank comprises the inside and outside shell of spherical tank and upper and lower section pillar, and described epimere pillar upper end and described inner casing are affixed, this affixed top, epimere pillar lower end connecting plate; Affixed bottom, described hypomere pillar upper end connecting plate; Be provided with thermal-protective coating between the connecting plate of described upper and lower part and connect by bolt; Bolt hole on described upper and lower part connecting plate and the thermal-protective coating is the slotted hole to the spherical tank centre of sphere.
The both sides of described bottom connecting plate are provided with baffle plate.
The utility model has not only effectively intercepted and interior jar has leaked the approach of heat by pillar, and the cold energy of blacked out content device is to the transmission on basis, simultaneously to the design of the displacement structure of the slotted hole of the centre of sphere, in can absorbing effectively jar because the cold contraction that low temperature produces.Reduced the entire equipment cost, Construction and Maintenance are convenient, and construction can extensively be promoted easily.
Jar was spherical storage tank or adopts inner container shore supports and that be used for the Cryo Heat Insulation pressurized container of storage low temperature liquid hydro carbons, liquified natural gas, liquid oxygen, liquid argon and liquid nitrogen to support in the utility model was applicable to.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A-A among Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, the adiabatic pillar of the anti-shrinkage of a kind of low temperature spherical tank comprises spherical tank inside and outside 8,10 and upper and lower section pillar 1,7, described epimere pillar 1 upper end and 8 welding of described inner casing, this welding top, epimere pillar 1 lower end connecting plate 3; Welding bottom, described hypomere pillar 7 upper ends connecting plate 6; Be provided with thermal-protective coating 5 between the described upper and lower part connecting plate 3,6 and pass through bolt 2 and connect; Bolt hole on described upper and lower part connecting plate 3,6 and the thermal-protective coating 5 is the slotted hole 11 to the spherical tank centre of sphere, make under low-temperature condition, the cold contraction that is produced by inner casing 8 can by upper and lower part connecting plate 3,6 and thermal-protective coating 5 on the slotted hole structure move.Hypomere pillar 7 is used for the support force that epimere pillar 1 transmits is delivered to Equipment Foundations; Inner casing 8 is used for storing as cryogenic medias such as liquefied hydrocarbon, liquified natural gas, liquid oxygen, liquid argon and liquid nitrogen; Sandwich layer thermal insulating material 9 is used for filling by inner casing 8 and shell 10 formed spaces, cuts off the heat transmission between inner casing 8 and the shell 10.
The both sides of described bottom connecting plate 6 are provided with baffle plate 4.Be used for preventing that thermal-protective coating 5 transition displacements from skidding off upper and lower part connecting plate 3,6.
The utility model is effectively to reduce to leak heat, the storage low temperature liquid medium of safety and nondestructive, designed the adiabatic corbeling of the anti-shrinkage of a kind of novel low temperature spherical tank, pillar adopts segmental structure, epimere pillar 1 adopts low temperature resistant material, the middle material with less thermal conductivity that adopts is as thermal-protective coating 5, and the mechanical property of thermal-protective coating 5 satisfies engineering demand; Employing arranges the slotted hole 11 to the centre of sphere, the cold contraction deformation of jar in absorbing; The hypomere pillar adopts conventional structural steel pipe, and the leaking heat of the pillar after improving obviously reduces, and satisfies engineering demand fully.Thermal-protective coating 5 is set, has not only cut off the transmission of cold energy, also can reduce the material temperature requirement of hypomere pillar simultaneously, can select conventional low alloy steel or structured steel pipe for use, and then the reduction equipment manufacturing cost, remarkable in economical benefits is the new structure of a technical security, economical rationality.
