According to the vertical cryogenic LNG storage tank, the reinforcing ribs on the tube body of the outer tank body are the ring-shaped-profile reinforcing ribs which are uniformly arranged on the outer circumference of the tube body of the outer tank body in the welding manner, the operation is convenient as the ring-shaped-profile reinforcing ribs are arranged on the outer circumference of the tube body of the outer tank body in the welding manner, and welding burrs are conveniently removed from the inner circumference of the tube body of the outer tank body after welding; after the ring-shaped-profile reinforcing ribs are arranged on the outer circumference of the tube body of the outer tank body in the welding manner, welded junctions do not exist 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 affected; and the ring-shaped-profile reinforcing ribs are uniformly arranged on the outer circumference of the tube body of the outer tank body in the welding manner, so that the volume of the inner tank body can be increased.
Description
Technical field
The utility model relates to a kind of vertical low-temperature liquefaction natural gas storage tank, the stiffening rib of the outer tank body of particularly a kind of vertical low-temperature liquefaction natural gas storage tank.
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 the low-temperature liquefaction rock gas to rock gas.Low-temperature liquefaction rock gas (LNG) is to adopt cryogenics, the low temperature liquid rock gas that makes with natural gas under certain pressure.
When storing the low-temperature liquefaction rock gas on the ground, can be with vertical low-temperature liquefaction natural gas storage tank.
Vertical low-temperature liquefaction natural gas storage tank has the low-temperature liquefaction natural gas tank, 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 axis normal of low-temperature liquefaction natural gas tank is in horizontal plane, and the lower end surface of low-temperature liquefaction natural gas tank is evenly equipped with leg.
During use, it is that subzero 162 ℃ ~ subzero 50 ℃, pressure are the low-temperature liquefaction rock gases of 0.65Mpa ~ 1.59Mpa that interior tank body 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 vertical low-temperature liquefaction natural gas storage tank 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 vertical low-temperature liquefaction natural gas storage tank of gap degree of vacuum between interior tank body and the outer tank body.
The utility model is realized with the following method.
Vertical low-temperature liquefaction natural gas storage tank has the low-temperature liquefaction natural gas tank, 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 axis normal of low-temperature liquefaction natural gas tank is in horizontal plane, the lower end surface of low-temperature liquefaction natural gas tank is evenly equipped with leg, and 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, the ring of the excircle of tank body cylindrical shell welding outside section bar stiffening rib is 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.
