Description

Technical Field

[0001] The utility model belongs to the technical field of helium production, in particular to a helium storage device. Background Art

[0002] Currently, crude helium and refined helium products are produced independently. Generally, the crude helium produced is transported through storage tanks to the refined helium production site for refining to form refined helium products.

[0003] Currently, the storage capacity of a single tank is only 4,200 cubic meters, insufficient to meet the production volume of crude helium. Furthermore, the price of a single tank is 1.89 million yuan (excluding installation costs), and the large land area required for installation makes it unsuitable for large-scale construction. Consequently, if problems arise, such as breakdowns of storage vehicles, road obstructions (e.g., due to traffic restrictions), or maintenance at refined helium production sites that are unable to receive crude helium, the crude helium production site may be unable to continue production, impacting annual crude helium production. Summary of the Invention

[0004] The purpose of the utility model is to provide a helium storage device, which solves the defects of the existing helium storage devices, such as small capacity and high manufacturing cost.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model provides a helium storage device, comprising a tube body, wherein the inner cavity of the tube body is divided into a plurality of independent spaces, and the plurality of independent spaces are sequentially connected to each other, wherein a crude helium gas inlet provided in the first independent space is connected to a first external device, and a crude helium gas outlet provided in the first independent space is connected to a second external device; and a compression structure is provided on one side of the first independent space near the inlet.

[0007] Preferably, a first control switch is provided at the crude helium outlet.

[0008] Preferably, a second control switch is provided on the connecting channel between two adjacent independent spaces.

[0009] Preferably, a safety valve is provided on the first independent space; and an emergency shut-off valve is provided at the crude helium inlet and / or crude helium outlet of the first independent space.

[0010] Preferably, the independent space at the tail is also provided with a reserved outlet communicating with other tube bodies.

[0011] Preferably, the first external device is a gas outlet of a crude helium production device.

[0012] Preferably, the second external equipment is a crude helium transport equipment.

[0013] Preferably, the pipe body is arranged below the ground.

[0014] Preferably, a first control switch is provided at the crude helium outlet; a second control switch is provided on the connecting channel between two adjacent independent spaces; and a reserved outlet communicating with other pipe bodies is also provided on the independent space at the tail.

[0015] Preferably, the tube body is arranged below the ground; a first control switch is provided at the crude helium outlet; a second control switch is provided on the connecting channel between two adjacent independent spaces; and a reserved outlet communicating with other tube bodies is also provided on the independent space at the tail.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model provides a helium storage device that divides a tube body with a larger capacity into sections. The capacity of each independent space can be set to the daily production of crude helium. When the gas volume is small, it is stored in the first section. When the pressure in the first section reaches the design point, it is introduced into the second section. A compression structure is provided on the first section. This design ensures that the pressure in the front section is always the highest. The higher the pressure, the easier it is to discharge the crude helium. At the same time, the provided compression structure can effectively increase the storage density of helium, thereby improving the storage efficiency of the helium storage device.

[0018] Furthermore, placing the helium storage device body below the ground can effectively utilize underground space and reduce the occupation of ground space.

[0019] Furthermore, a reserved outlet is provided on the independent space at the tail, which is convenient for adding a storage section later and for discharging from the rear section using a mobile pressurizing device in an emergency. At the same time, when all the helium in the tube body is discharged and the pressure in the tube body is lower than the preset value, an inert gas such as nitrogen is injected from the reserved outlet of the last section to push the helium to the front end and discharge it from the crude helium outlet.

[0035] In this embodiment, the crude helium gas to be stored is transported from the crude helium gas inlet of the first independent space to the tube body 1 by means of the compression structure 2. When the pressure of the first independent space increases to the design pressure, the second control switch between the first independent space and the next independent space is controlled to allow the crude helium gas to be stored to enter the next independent space through the first independent space. In this way, the pressure of the first space is always guaranteed, making it convenient for the gas to be taken out from the crude helium gas outlet of the first independent space.

[0036] By setting up a compression structure, the gas inside the tube can be compressed, thereby increasing the gas storage capacity in the tube and improving storage efficiency. This is particularly important for application scenarios that require storing large amounts of helium. At the same time, the compression structure can not only compress the gas to increase the storage capacity, but also adjust the gas output speed and pressure by controlling the degree of compression to meet different application requirements.
