Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to a cryogenic medium storage tank that is easy to use. Background Technology

[0002] Currently, cryogenic storage tanks all adopt a double-walled cylindrical structure, including an inner container and an outer container. The inner container, as the most important component of the cryogenic storage tank, stores mostly flammable, explosive, and harmful liquefied gases and cryogenic liquids (such as liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, liquid carbon dioxide, liquid ethylene, etc.).

[0003] Existing cryogenic storage tanks have low integration levels, requiring pre-planning support before use. Furthermore, an additional vaporizer is needed to work in conjunction with the tank, which is quite inconvenient.

[0004] In view of this, there is an urgent need for a cryogenic medium storage tank that is easy to use. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A convenient cryogenic medium storage tank includes: a tank body, a liquid outlet pipe, a heat exchange pipe, and a vent pipe. One end of the liquid outlet pipe is connected to the tank body, and the other end is connected to the liquid inlet of the heat exchange pipe. The vent pipe is connected to the vent outlet of the heat exchange pipe. A first valve is provided on the liquid outlet pipe for opening and closing the liquid outlet pipe. A second valve is provided on the vent pipe for opening and closing the vent pipe. The bottom of the tank is provided with a base.

[0007] The vertical cross-sectional area of ​​the base is larger than the vertical cross-sectional area of ​​the tank.

[0008] A pressure gauge is installed on the tank.

[0009] The tank is equipped with a level gauge.

[0010] A vacuum measuring tube window is provided at the top of the tank.

[0011] The top of the tank is equipped with a vacuum tube window.

[0012] The heat exchange tube is located on the circumferential side of the tank.

[0013] A pressure booster is provided on the circumferential side of the tank.

[0014] A liquid outlet valve is provided on the circumferential side of the tank.

[0015] The heat exchange tube has a number of fins on its circumferential side, and the fins extend along the extension direction of the heat exchange tube.

[0016] The above-described structure of this utility model can achieve the following beneficial effects: The inner tank of the vessel is used to store cryogenic liquid media. When in use, the first and second valves are opened, and the cryogenic liquid media enters the heat exchange tubes, where it exchanges heat with the outside air. The gas after heat exchange is then input to the required equipment through the outlet pipe. Because the vessel is equipped with heat exchange tubes, there is no need for an external vaporizer for vaporization. Furthermore, because the base at the bottom of the vessel is used to support it, there is no need to pre-set a support structure. It can be used immediately upon arrival, saving time and costs. It is suitable for small-volume storage tanks and has a high degree of integration. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] refer to Figure 1 The illustrated cryogenic medium storage tank includes: a tank body 1 (the tank body 1 consists of an outer tank and an inner tank disposed within the outer tank, with a high-vacuum interlayer filling the space between the inner and outer tanks), a liquid outlet pipe 2, a heat exchange pipe 3 (preferably disposed on the circumferential side of the tank body 1), and a vent pipe 4 (also including a pressure booster, a pressure reduction system, a metering system, a safety shut-off system, an instrumentation and control system, etc.). One end of the liquid outlet pipe 2 is connected to the inner tank of the tank body 1, and the other end is connected to the liquid inlet of the heat exchange pipe 3. The vent pipe 4 is connected to the vent outlet of the heat exchange pipe 3. A first valve 5 is provided on the liquid outlet pipe 2 for opening and closing the liquid outlet pipe 2. A second valve 6 is provided on the vent pipe 4. Valve 6 is used to open and close the outlet pipe 4; a base 7 is provided at the bottom of the tank body 1. Thus, the inner tank of the tank body 1 is used to store the cryogenic liquid medium. When in use, the first valve 5 and the second valve 6 are opened, and the cryogenic liquid medium enters the heat exchange tube 3 (multiple heat exchange tubes 3 can be arranged in parallel). The heat exchange tube 3 exchanges heat with the outside air, and the gas after heat exchange is input to the required equipment through the outlet pipe 4. Since the heat exchange tube 3 is provided on the tank body 1, there is no need to connect an external vaporizer for vaporization. Furthermore, since the base 7 is provided at the bottom of the tank body 1 to support the tank body 1, there is no need to set up a support structure in advance. It can be used immediately upon arrival, saving time and cost, and is suitable for small-volume storage tanks.

[0023] like Figure 1 As shown, the cross-sectional area of ​​the base 7 in the vertical direction is larger than that of the tank 1 in the vertical direction. Thus, the larger base 7 can stably support the tank 1.

[0024] like Figure 1 As shown, a pressure gauge 8 and a level gauge 9 are installed on the tank body 1 to monitor the pressure and level inside the tank.

[0025] like Figure 1 As shown, since the vacuum degree between the inner tank and the outer tank affects the performance of the storage tank, a vacuum measuring tube window 10 is provided on the top of the tank body 1 to facilitate the measurement of the vacuum degree between the inner tank and the outer tank. A vacuum extraction tube window 11 is also provided on the top of the tank body 1. When the vacuum degree is insufficient, the vacuum extraction tube window 11 is used to extract a vacuum between the inner tank and the outer tank.

[0026] like Figure 1 As shown, a pressure booster 12 is provided on the circumferential side of the tank body 1. When the pressure inside the tank body 1 is insufficient, the pressure booster 12 is used to increase the pressure to meet the usage requirements.

[0027] like Figure 1 As shown, in order to further improve applicability, a liquid outlet valve 13 is provided on the ring side of the tank body 1. The low-temperature liquid medium in the tank body 1 can be discharged by opening and closing the liquid outlet valve 13 as needed.

[0028] Further optimizations include, for example Figure 2 As shown, in order to improve heat exchange efficiency, several fins are provided on the circumferential side of the heat exchange tube 3. The fins extend along the extension direction of the heat exchange tube 3. By providing several fins, the heat exchange area is increased and the heat exchange efficiency is improved.

[0029] In summary, the inner tank of tank 1 is used to store cryogenic liquid media. When in use, the first valve 5 and the second valve 6 are opened, and the cryogenic liquid media enters the heat exchange tube 3. It exchanges heat with the outside air through the heat exchange tube 3, and the gas after heat exchange is input to the required equipment through the gas outlet pipe 4. Since the heat exchange tube 3 is installed on tank 1, there is no need for an external vaporizer for vaporization. Furthermore, since the base 7 is installed at the bottom of tank 1 to support tank 1, there is no need to set up a support structure in advance. It can be used immediately upon arrival, saving time and cost. It is suitable for small-volume storage tanks and has a high degree of integration.

[0030] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
