Abstract
The invention relates to a low temperature liquefied natural gas tank container, which includes a load-bearing frame. A low temperature liquefied natural gas tank is disposed in the load-bearing frame. The low temperature liquefied natural gas tank is equipped with an inner tank body and an outer tank body that are nested together. A gap is reserved between the inner tank body and the outer tank body. The inner tank body is coated with a flexible aluminum foil heat preservation quilt, and circular profile reinforcing ribs are uniformly distributed and welded on the external circumference of the outer tank body cylinder. The reinforcing ribs on the outer tank body cylinder are circular profiles uniformly distributed and welded on the external circumference of the outer tank body cylinder. Welding of the circular profile reinforcing ribs on the external circumference of the outer tank body cylinder is convenient, and after welding, removal of wielding burrs from the internal circumference of the outer tank body cylinder is also convenient. After the circular profile reinforcing ribs are welded on the external circumference of the outer tank body cylinder, no welded junction is left in the gap between the inner tank body and the outer tank body, so that the vacuum degree of the gap between the inner tank body and the outer tank body is not influenced. The circular profile reinforcing ribs are uniformly distributed and welded on the external circumference of the outer tank body cylinder, and the volume of the inner tank body can be increased.
Description
Technical field
The present invention relates to a kind of low-temperature liquefaction rock gas pot type shipping container, particularly the stiffening rib of the outer tank body of a kind of low-temperature liquefaction rock gas pot type shipping container.
Background technique
Rock gas is a kind of energy of good combination property.The natural gas volume of equal in quality is 600 times of LNG Liquefied natural gas volume.For convenient transportation and storage, make LNG Liquefied natural gas to rock gas.LNG Liquefied natural gas (LNG) is to adopt cryogenics, the liquified natural gas that makes with natural gas under certain pressure.
That low-temperature liquefaction rock gas pot type shipping container claims again container-type low-temperature liquefaction gas tank with low-temperature liquefaction rock gas pot type Container Transport LNG Liquefied natural gas in highway, railway, water transportation.Low-temperature liquefaction rock gas pot type shipping container has and shields and the cube shaped load-bearing frame of lifting effect; the low-temperature liquefaction natural gas tank is arranged in load-bearing frame; the tank body surrounding load-bearing frame of low-temperature liquefaction natural gas tank is cube shaped framework, and the outside dimensions of cube shaped framework is equal to the size of ISO freight container fully.Low-temperature liquefaction rock gas pot type shipping container is used for transportation and the storage of low-temperature liquid gas, and its is fit to waterborne, all kinds of means of transportation in land, the characteristics such as have safe and reliable, convenient for maintaining, stowage is large, and equipment self-weight is light, and cost of transportation is low.
The low-temperature liquefaction natural gas tank has interior tank body and the outer tank body that is nested together, interior tank body and outer tank body have cylindrical drum, there is ellipsoidal head at the two ends of cylindrical shell, gapped between interior tank body and outer tank body, the outside of interior tank body is coated with flexible aluminium foil thermal insulation quilt, is evenly equipped with the ring stiffening rib on the cylindrical shell of outer tank body.In order to improve conveying efficiency, reduce cost of transportation, under the prerequisite that meets the communications and transportation standard, the low-temperature liquefaction natural gas tank is large as much as possible, and the length of low-temperature liquefaction natural gas tank can reach 12 meters at present, and diameter can reach 2.5 meters, and volume can reach more than 50 cubic metre.
Low-temperature liquefaction rock gas pot type shipping container in use, it is that subzero 162 ℃ ~ subzero 50 ℃, pressure are the low-temperature liquefaction rock gases of 0.65Mpa ~ 1.59Mpa that the interior tank body of low-temperature liquefaction natural gas tank is used for the splendid attire temperature, gap between interior tank body and outer tank body will be evacuated, the gap of high vacuum and aluminium foil thermal insulation quilt make the LNG Liquefied natural gas in the low-temperature liquefaction natural gas tank be in adiabatic state, guarantee that the LNG Liquefied natural gas in the low-temperature liquefaction natural gas tank is in lower temperature.
Because outer tank body is in use under the environment of vacuum, the cylindrical shell of outer tank body will have stiffening rib.In prior art, the stiffening rib on outer tank body cylindrical shell is the uniform ring section bar that is welded on the cylindrical shell inner circumference, and the ring section bar can be angle steel.This low-temperature liquefaction rock gas semi-mounted tank car has following deficiency:
1. ring section bar stiffening rib is the uniform inner circumference that is welded on outer tank body cylindrical shell, ring section bar stiffening rib is in gap between interior tank body and outer tank body, ring section bar stiffening rib occupies the space of interior tank body and outer tank body gap, affects the increase of inner canister body bulk;
2. the ring of the inner circumference of tank body cylindrical shell welding outside section bar stiffening rib is because of narrow space, and weld job is very inconvenient, and after welding, it is also very inconvenient that the inner circumference of tank body cylindrical shell is removed the welding burr outside;
3. after the inner circumference of tank body cylindrical shell has welded ring section bar stiffening rib outside, the inner circumference of outer tank body cylindrical shell has a large amount of weld bonds, have the pore of different shape in weld bond, in pore, absorption has gas, the degree of vacuum of tank body and outer tank body gap in the existence impact of pore.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of welding, flash removed easily, can increase the inner canister body bulk, not affect the low-temperature liquefaction rock gas pot type shipping container of interior tank body and outer tank body gap degree of vacuum.
The present invention is achieved using the following method.
low-temperature liquefaction rock gas pot type shipping container has and shields and the cube shaped load-bearing frame of lifting effect, the low-temperature liquefaction natural gas tank is arranged in load-bearing frame, the low-temperature liquefaction natural gas tank has interior tank body and the outer tank body that is nested together, interior tank body and outer tank body have cylindrical drum, there is ellipsoidal head at the two ends of cylindrical shell, gapped between interior tank body and outer tank body, the outside of interior tank body is coated with flexible aluminium foil thermal insulation quilt, be evenly equipped with the ring stiffening rib on the cylindrical shell of outer tank body, stiffening rib on outer tank body cylindrical shell is the uniform ring section bar that is welded on outer tank body cylindrical shell excircle.
Stiffening rib on the outer tank body cylindrical shell of the present invention is the uniform ring section bar that is welded on outer tank body cylindrical shell excircle, spacious because of the space during ring of the excircle of tank body cylindrical shell welding outside section bar stiffening rib, weld job is convenient, after welding, it is also very convenient that the inner circumference of tank body cylindrical shell is removed the welding burr outside; Ring section bar stiffening rib be welded on the excircle of outer tank body cylindrical shell complete after, there is no weld bond in interior tank body and outer tank body gap, do not affect the degree of vacuum of interior tank body and outer tank body gap; Ring section bar stiffening rib is the uniform excircle that is welded on outer tank body cylindrical shell, and the inner canister body bulk can increase.
Below in conjunction with accompanying drawing, the present invention is further described.
