Technical Field

The invention relates to the field of LNG storage tanks, in particular to an integrated flat pressure container array tank with a tension rod.

Background

Liquefied Natural Gas (LNG), the main component of which is methane, is known as the cleanest fossil energy on earth. Is colorless, tasteless, nontoxic and noncorrosive, and is a clean energy source.

LNG is stored in dedicated containers. Conventional LNG tanks are typically thin-walled spheres or cylinders because of the high internal pressure. The reason for using circular or cylindrical tank bodies is that the shells of these tank body structures are uniformly stressed and can be made of homogeneous materials, but the spherical or cylindrical tank bodies have a serious disadvantage and insufficient space utilization rate, thereby causing waste of space of ships, automobiles, buildings and the like.

Detailed Description

As shown in fig. 1 to 3, an embodiment of the present invention provides an integrated flat type pressure vessel array tank with tension rods, which includes two rectangular end plates 10 arranged in parallel and at least one partition plate 20 arranged between the two rectangular end plates 10. The inner sides of the two rectangular end plates 10 are fixedly provided with frame structures 30, and the frame structures 30 of the two are connected together through a plurality of tension rods 40. The partition plate 20 is provided with a circular hole 21 for the tension rod 40 to pass through.

The edge of the rectangular end plate 10 and the edge of the adjacent partition plate 20 are connected together through the arc plate 50, the arc plate 50 surrounds the rectangular end plate 10 for one circle, and the closed unit 60 is formed by enclosing the rectangular end plate 10 and the adjacent partition plate 20.

The number of the partition plates 20 is more than one (as shown in fig. 2), except that the arc-shaped plates 50 are arranged between the rectangular end plate 10 and the partition plates 20, the edges of the adjacent partition plates 20 are connected together through the arc-shaped plates 50 arranged in a surrounding manner, so as to form a closed unit 60. The respective sealing units 60 communicate with each other through the circular holes 21 of the partition plate 20, thereby constituting an integrated flat type pressure vessel array tank.

When the number of the partition plates is equal to one, the partition plate 20 is disposed between the two rectangular end plates 10; the two rectangular end plates 10 are connected with the edges of the rectangular end plates 10 through the arc-shaped plates 50 to form a closed unit 60. The two closed units at the two sides of the rectangular end plate 10 are communicated through the round holes 21 at the middle part of the rectangular end plate to form an integrated flat pressure container array tank.

As shown in fig. 2 to 4, in the present embodiment, the frame structure 30 is a grid structure formed by criss-cross bar-shaped steel plates; the strip steel plate 31 is perpendicularly connected to the rectangular end plate 10, and has an inner edge connected to the inner surface of the rectangular end plate 10 by welding and an outer edge for connection to the tension bar 40. The tension bar 40 has a cross-shaped cross-section and is connected to the intersection of the steel bar plates 31 in the frame structure 30. The tension rods 40 are distributed in an array shape, the distance between every two adjacent tension rods 40 is twice the grid width of the frame structure 30, and due to the arrangement mode, each area of the rectangular end plate 10 is provided with one tension rod 40 for drawing, so that the problem that the deformation of the middle of the rectangular end plate 10 is too large is solved.

In some embodiments, each spacer plate 20 has the same shape as the two rectangular end plates 10, and the opposite edges are parallel to each other. Each spacer plate 20 equally divides the space between the rectangular end plates 10. The edges of the arc-shaped plates 50 are connected with the spacing plate 20 or the rectangular end plate 10 by means of welding.

In some embodiments, the middle of the arcuate plate 50 is convex toward the outside. In a specific embodiment, the shape of the protrusion is circular arc, and for a cross section perpendicular to the edge line of the partition plate 20, the intersection line of the circular arc plate 50 and the cross section is a semicircle having a diameter equal to the distance between the rectangular end plate 10 and the nearest partition plate 20.

In this embodiment, the tension bar 40 can pull the two rectangular end plates 10, so that the positions between the rectangular end plates 10 are not changed when the internal pressure is applied, and the stability of the integrated flat pressure container array tank is enhanced. The side wall of each closed unit 60 is an arc-shaped plate, after a plurality of closed units 60 are combined together, the side wall (arc-shaped plate 50) of each closed unit 60 forms a corrugated structure, the convex arc-shaped plate 50 has better strength, and the partition plate 20 can restrict the edge of the arc-shaped plate 50 and prevent the edge from expanding outwards in the pressure-bearing process. In addition, the corrugated structure and the floating partition plate 20 (which is only connected with the arc-shaped plates 50) can make the stress of each arc-shaped plate 50 more uniform (when the arc-shaped plate 50 of a certain closed unit 60 has a larger deformation, the floating partition plate 20 connected with the same can transfer the deformation to the arc-shaped plates of other closed units 60 by the partition plate 20, so as to achieve the effect of load balancing), and avoid the damage of local concentrated stress on the junction structure. In conclusion, the integrated flat pressure vessel array tank has good mechanical properties and the capacity of bearing internal pressure.

The rectangular end plate 10 is pulled and connected through the frame structure 30 and the tension rods 40, so that the area of the rectangular end plate 10 can be freely expanded according to the volume requirement, and the problem that the planar rectangular end plate 30 is difficult to bear large internal pressure under the condition of no support is avoided. As the length and width of the rectangular end plate 10 are larger, the area of the frame structure 30 and the number of tension rods 40 should be increased simultaneously. The surface of the flat pressure vessel can be provided with an insulating layer, and the LNG inlet and outlet can be opened on the rectangular end plate 10.

The integrated flat type pressure vessel array tank is shaped closer to a cube as the length and width of the rectangular end plate 10 is larger, and the occupation of the cube vessel is generally minimized. In the process of the embodiment, the information of the shape of the rectangular end plate 10, the distance between the two rectangular end plates 10, the number of the partition plates 20, and the like can be configured according to the scene to be applied. When the area of the rectangular end plate 10 is increased, the area of the frame structure 30 and the number of tension rods 40 should be increased simultaneously.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
