Problems solved by technology
[0009] Both the anchor belt system and the inner tank are made of X7Ni9 steel. Usually, the materials of the two structures are purchased at the same time, but the anchor belt system needs to be used about one and a half years earlier for the inner tank, which greatly advances the procurement of X7Ni9 steel for the inner tank. The hasty procurement time is not conducive to the procurement of more cost-effective materials, which affects the vigorous application and promotion of this anchor belt system

Embodiment Construction
[0039] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but only to illustrate the essence of the technical solutions of the present invention.
[0040] The purpose of the present invention is to solve the problems existing in conventional anchoring facilities at present, and propose a new inner tank anchoring device and anchoring method for cryogenic storage tanks. The device can achieve the ability to resist the inner tank overturning under earthquake excitation, and has a simple structure and is easy to manufacture Install.
[0041] The cryogenic storage tank includes an inner tank and an outer wall, an annular space is formed between the inner tank and the outer wall, a bottom ring ...

The invention relates to a low-temperature storage tank inner tank anchoring device and anchoring method. A low-temperature storage tank comprises an inner tank and an outer wall, wherein an annular space is formed between the inner tank and the outer wall, the bottom of the inner tank is provided with a bottom ring plate, the device comprises a first low-temperature steel bar, a low-temperature sleeve and a second low-temperature steel bar, one end of the first low-temperature steel bar is connected with the bottom ring plate of the inner tank, the other end of the first low-temperature steelbar is detachably connected with one end of the low-temperature sleeve, one end of the second low-temperature steel bar is connected with the outer wall, and the other end of the second low-temperature steel bar is detachably connected with the other end of the low-temperature sleeve. According to the device, the low-temperature storage tank inner tank can achieve inner tank overturning capacityunder the anti-seismic excitation, the structure is simple and reliable, and is easy to manufacture and install, the inner tank is not easy to damage, and the leakage risk of liquid in the inner tankis avoided.
Description
technical field [0001] The invention relates to the technical field of cryogenic liquid transmission and distribution, in particular to an anchoring device and an anchoring method for an inner tank of a cryogenic storage tank. Background technique [0002] As an important storage device for cryogenic liquid fuel plants, cryogenic storage tanks have very high safety requirements. Generally, cryogenic storage tanks can be divided into single-containment tanks, double-containment tanks and full-containment tanks according to inclusiveness. These three types of storage tanks all contain inner tanks containing cryogenic liquids. [0003] Under earthquake excitation, the liquid in the inner tank sloshes, which will generate an overturning moment for the entire inner tank. According to the requirements of the specification API625, when the overturning moment is greater than 1.57 times the anti-overturning capacity of the storage tank, anchoring measures must be taken for the inner ...
