Large-scale vacuum insulated cryogenic storage
Implementations of the present disclosure generally relate to an apparatus for large-scale external pressure storage, and more particularly for large-scale storage of liquid hydrogen and other products that require evacuated insulation. In some examples, a plate for a storage apparatus is provided. The plate a body that includes a beveled joint with the body having a nominal thickness at the beveled joint. The beveled joint is configured to be welded to a corresponding beveled joint of an adjacent plate.
1. A plate for an outer vessel of a storage apparatus, comprising:
a body, the body having:
a central portion with a first thickness;
a beveled surface that extends from the central portion to an outer edge; and
the outer edge having a vertical surface connected to the beveled surface; and
a beveled joint that includes the vertical surface of the outer edge and a portion of the beveled surface, the beveled joint having a second thickness less than the first thickness at the central portion of the body, wherein the beveled joint is configured to be welded to a corresponding beveled joint of an adjacent plate.
2. The plate of claim 1 , wherein the beveled joint is disposed around the entire perimeter of the body.
3. The plate of claim 1 , wherein the second thickness of the beveled joint is about 30 percent to about 70 percent of the first thickness at the central portion of the body.
4. The plate of claim 1 , wherein one or more stiffeners are coupled to the body inside the beveled joint.
5. The plate of claim 4 , wherein the one or more stiffeners comprises two parallel stiffeners.
6. The plate of claim 4 , wherein the one or more stiffeners are arranged to conform to a perimeter of the body.
7. The plate of claim 1 , wherein the portion of the beveled surface and the beveled surface have a different contour.
8. A plate arrangement for a storage apparatus, comprising:
a plurality of plates, each plate includes:
a body, the body having:
a central portion with a first thickness;
a beveled surface that extends from the central portion to an outer edge; and
the outer edge having a vertical surface connected to the beveled surface; and
a beveled joint including the vertical surface of the outer edge and a portion of the beveled surface, the beveled joint having a second thickness less than the first thickness at the central portion of the body, wherein each plate is welded at the beveled joint to the beveled joint of at least one other plate of the plurality of plates.
9. The plate arrangement of claim 8 , wherein the beveled surface surrounds the central portion of the body.
10. The plate arrangement of claim 9 , wherein at least one stiffener is coupled to the central portion within the boundary of the beveled surface.
11. The plate arrangement of claim 10 , wherein the at least one stiffener coupled to the central portion of a first plate of the plurality of plates does not contact a second plate of the plurality of plates.
12. The plate arrangement of claim 10 , wherein the at least one stiffener is arranged in a geometry that conforms with a perimeter geometry of the body defined by an outer edge of the body.
13. The plate arrangement of claim 9 , wherein the second thickness of the beveled joint is about 30 percent to about 70 percent of the first thickness at the central portion of the body.
14. The plate arrangement of claim 8 , wherein the portion of the beveled surface and the beveled surface have a different contour.
15. A large scale cryogenic storage vessel, comprising:
a plurality of plates in a spherical arrangement to form a thermal vacuum chamber, wherein each plate includes:
a body including a central portion and an outer portion surrounding the central portion; and
a stiffener disposed on the body completely surrounding the central portion and contoured to the shape of a perimeter of the outer portion.
16. The vessel of claim 15 , wherein one or more stiffeners do not contact another plate of the plurality of plates.
17. The vessel of claim 15 , wherein an equator course of the vessel does not include a plate of the plurality of plates, and wherein the equator course is formed from an arrangement of second plates.
18. The vessel of claim 15 , wherein at least two of the plates have different stiffeners contoured to different perimeters of the outer portion.
