Embodiment 1

[0058] like figure 1 As shown, the gas storage tank includes a tank body 1 . The tank body 1 includes an inner container 11 . The radial section of the liner 11 is circular. The inner tank 11 is provided with a cavity 111 for storing liquefied gas. The inner tank 11 is made of pure metal, alloy or resin, which prevents the leakage of liquefied gas in the cavity 111 and plays a sealing role. The outer surface of the liner 11 is covered with a layer of first fiber reinforced material layer 12 . The first fiber-reinforced material layer 12 is formed by heating and curing the first fiber-reinforced material wire or the first fiber-reinforced material strip wrapped around the outer surface of the inner container 11 .

[0059] The first fiber-reinforced material layer 12 is a first fiber-reinforced resin layer, and the first fiber-reinforced resin layer includes first fibers and a first resin. Wherein, the first fiber is selected from glass fiber, carbon fiber, metal fiber, bor...

Embodiment 2

[0063] like figure 2 As shown, the gas storage tank includes a tank body 1 . The tank body 1 includes an inner container 11 . The radial section of the liner 11 is circular. The inner tank 11 is provided with a cavity 111 for storing liquefied gas. The inner tank 11 is made of pure metal, alloy or resin, which prevents the leakage of liquefied gas in the cavity 111 and plays a sealing role. The outer surface of the liner 11 is covered with two layers of first fiber reinforced material layers 12 . Two layers of the first fiber reinforced material layer are stacked successively along the direction perpendicular to the outer surface of the liner 11 . The first fiber-reinforced material layer 12 is formed by heating and curing the first fiber-reinforced material wire or the first fiber-reinforced material strip wrapped around the outer surface of the inner container 11 . A support structure is provided between the two first fiber reinforced material layers 12 . The support ...

Embodiment 3

[0073] Different from Example 2, such as Figure 5 and 6As shown, the radial section of the liner 11 in this embodiment is a rectangle with rounded corners. The support structure between the two layers of the first fiber reinforced material layer 12 is composed of one or more of the honeycomb structure material, grid structure material and wave structure material, the holes on the honeycomb structure material or the grid structure material The holes extend in a direction perpendicular to the first layer of fiber reinforced material 12 . In the preferred solution of this embodiment, the support structure is composed of a layer of honeycomb panels 22 . The holes 221 on the honeycomb panel 22 extend in a direction perpendicular to the first fiber reinforced material layer 12 . The heat radiation layer 01 is arranged between the inner first fiber reinforced material layer 12 and the honeycomb panel 22 . The inner surface of the honeycomb panel 22 is bonded or mechanically inte...

Abstract

The invention discloses a gas storage tank. The gas storage tank is characterized by comprising at least one tank body, and each tank body comprises an inner container, wherein a containing cavity is formed in the inner container; each containing cavity is used for storing liquefied gas; and the outer surface of each inner container is wrapped by at least one first fiber reinforcing material layer. According to the gas storage tank of the embodiment, the designability, fatigability and other performance of fiber reinforcing materials are sufficiently utilized, and therefore the gas storage tank has the superior pressure resisting performance. Compared with a traditional stainless steel storage tank, the gas storage tank of the embodiment has the obvious weight advantage under the situation that the same pressure level is reached, and the weight can be reduced by 50%-65%. It means that the transporting cost can be reduced. Compared with the traditional stainless steel storage tank, the pressure level of the gas storage tank of the embodiment can be improved by 50% under the situations of the same weight and the same volume.

Description

technical field [0001] The invention relates to a gas storage tank. Background technique [0002] It is used to store gas with a certain pressure, especially for storage tanks for storing liquefied gas, not only has certain weight index requirements, but also higher technical index requirements, such as pressure rating, bending resistance, impact resistance, etc., specific There are bending stiffness, bending strength, tensile stiffness, tensile strength, compressive stiffness, compressive strength, impact stiffness, impact strength, etc. If the storage tank is made of all-metal materials, in order to meet certain technical requirements, the wall thickness of the storage tank will increase, thereby increasing the weight of the storage tank and the space it occupies, which means increasing the transportation cost . Contents of the invention [0003] The object of the present invention is to provide a gas storage tank in order to overcome the deficiencies in the prior art....
