Description
Technical field
The utility model relates to a kind of low-temperature liquefaction rock gas pot type shipping container, the stiffening rib of the outer tank body of particularly 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.Transportation for convenience and storage will be made 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.
Be that low-temperature liquefaction rock gas pot type shipping container claims container-type low-temperature liquefaction gas tank again with low-temperature liquefaction rock gas pot type containerized 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 the load-bearing frame; load-bearing frame is cube shaped framework around the tank body of low-temperature liquefaction natural gas tank, 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 the transportation and the storage of low-temperature liquid gas, and its is fit to waterborne, all kinds of means of transportation in land, characteristics such as have safe and reliable, convenient for maintaining, stowage is big, 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 all have cylindrical drum, there is ellipsoidal head at the two ends of cylindrical shell, gapped between interior tank body and the 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 big 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 the 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 the prior art, the stiffening rib on the 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 an 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 be interior tank body and outside in the gap between the tank body, the space in gap between tank body and the outer tank body in ring section bar stiffening rib occupies, the increase of tank body volume in the influence;
2. the ring of the inner circumference of tank body cylindrical shell welding outside section bar stiffening rib is because the space is narrow and small, and weld job is very inconvenient, and after the 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 the weld bond, be adsorbed with gas in the pore, the degree of vacuum in gap between tank body and the outer tank body in the existence influence of pore.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of welding, flash removed easily, can increase interior tank body volume, not influence the low-temperature liquefaction rock gas pot type shipping container of gap degree of vacuum between interior tank body and the outer tank body.
The utility model is realized with 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 the 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 all have cylindrical drum; there is ellipsoidal head at the two ends of cylindrical shell; gapped between interior tank body and the 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, the stiffening rib on the 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 utility model is the uniform ring section bar that is welded on outer tank body cylindrical shell excircle, outside during the excircle of tank body cylindrical shell welding ring section bar stiffening rib because the space spaciousness, weld job is convenient, after the 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 intact after, do not have weld bond in the gap between interior tank body and the outer tank body, do not influence the degree of vacuum in gap between interior tank body and the outer tank body; Ring section bar stiffening rib is the uniform excircle that is welded on outer tank body cylindrical shell, and interior tank body volume can increase.
Below in conjunction with accompanying drawing, the utility model is further described.
