Description

Technical Field

[0001] This application belongs to the field of safe utilization technology of flammable and explosive media, and in particular relates to a storage device with bidirectional dilution function. Background Technology

[0002] Liquid hydrogen, as a highly efficient and clean energy carrier, is increasingly widely used in aerospace, new energy, and other fields. However, liquid hydrogen has an extremely low boiling point (-252.77℃), and after leakage, it easily vaporizes into a large amount of hydrogen gas. Furthermore, hydrogen gas is flammable and explosive. If leakage is not handled promptly or properly, it can easily lead to safety accidents.

[0003] Currently, the leakage prevention and control system of existing storage devices is not perfect: First, the coverage of leakage handling devices is low, and the devices have single functions, which cannot cope with the phase change from liquid to gas after hydrogen leakage, resulting in blind spots in safety control; Second, the lack of a flow guiding structure design makes it difficult to efficiently guide the leaked medium, and instead easily causes the leaked medium to flow back and the inert gas to overflow, leading to secondary risks in the handling process. Utility Model Content

[0004] This application aims to provide a storage device with bidirectional dilution function, which can adapt to the phase change after media leakage, effectively prevent backflow of leaked media and overflow of inert gas, and significantly improve the safety and convenience of media storage and use.

[0009] In an optional embodiment of this application, the flow guiding member extends along a first direction and has a closed end and an open end. The open end is sealed to the storage tank, and the flow guiding member is provided with a first outlet and a second outlet arranged opposite to each other along a second direction. Along the second direction, the first outlet is located on the upper side of the flow guiding member, and the second outlet is located on the lower side of the flow guiding member.

The second check valve is configured to allow unidirectional flow of the leaking liquid medium from the second control valve side to the second dilution tank side.

[0013] In an optional embodiment of this application, a third control valve is connected to the portion of the storage tank that forms a flow guide cavity with the flow guide member, and the third control valve is located within the flow guide cavity.

[0014] In an optional embodiment of this application, the control mechanism includes: a temperature sensor disposed on the flow guiding member and located within the flow guiding cavity, for collecting the temperature within the flow guiding cavity; and a controller connected to the temperature sensor, the first dilution mechanism, and the second dilution mechanism. The controller is configured to control the first dilution mechanism to operate when the temperature within the flow guiding cavity is equal to or greater than the vaporization temperature of the medium, and to control the second dilution mechanism to operate when the temperature within the flow guiding cavity is less than the vaporization temperature of the medium.

[0028] To make the above and other features and advantages of this application clearer, the application is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art and are exemplary only, not restrictive.

[0029] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise stated, "a plurality of" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects.

[0030] Because existing hydrogen storage devices typically only handle liquid hydrogen leaks in either liquid or gaseous states, they cannot adaptively adjust the handling method based on the phase changes of the leaking medium. For example, some hydrogen storage devices only have liquid flow channels; when liquid hydrogen leaks and rapidly vaporizes into hydrogen gas, the gaseous hydrogen cannot be effectively collected and diluted, causing it to diffuse into the air and create a safety hazard. Other hydrogen storage devices only have extraction structures; when leaked liquid hydrogen is not completely vaporized, it easily accumulates in the channels and cannot be quickly removed, also posing a safety risk.

[0031] Therefore, this application provides a storage device with bidirectional dilution function. This storage device can automatically switch processing functions according to the phase state (liquid or gas) of the leaked medium, realize the rapid dilution of liquid and gaseous leaked media, and effectively prevent the backflow of leaked media and the overflow of inert gas. It significantly improves the safety and convenience of media storage and use, and can be widely used in aerospace, new energy and other fields.

[0032] Specifically, the storage device in this application embodiment can be used to store flammable and explosive media, which can be gaseous or liquid media, and the liquid media can be liquid hydrogen, but is not limited to liquid hydrogen.

[0033] Figure 1 This is a schematic diagram of the structure of a storage device provided according to an embodiment of this application. Please refer to... Figure 1The storage device 100 may include a storage tank 1, a flow guiding member 2, a first dilution mechanism 3, a second dilution mechanism 4, and a control mechanism 5.

[0034] Storage tank 1 has a storage chamber S1 for storing a target medium, which is at risk of leakage during storage and transportation. For example, the target medium may be liquid hydrogen.

[0035] The flow guiding member 2 is disposed on at least a portion of the outer side of the storage tank 1 and together with the storage tank 1 forms a flow guiding cavity S2, which is used to collect the leaked medium overflowing from the storage tank 1. Depending on the temperature inside the flow guiding member 2, the leaked medium can be a gaseous leaked medium (such as gaseous hydrogen), a liquid leaked medium (such as liquid hydrogen), or a mixture of both.

[0036] The flow guiding cavity S2 is a closed cavity structure, which can provide a sealed collection space for the leaked medium, effectively preventing the leaked medium from spreading to the external environment. Specifically, the flow guiding member 2 can be disposed on the outside of a portion of the storage tank 1 and sealed to that portion of the storage tank 1 to form the flow guiding cavity S2 together with the storage tank 1, that is, the flow guiding member 2 covers a portion of the storage tank 1; or the flow guiding member 2 can be disposed on the outside of the entire storage tank 1 to form the flow guiding cavity S2 together with the storage tank 1, that is, the flow guiding member 2 covers the entire storage tank 1. This application does not limit this.

[0037] The first dilution mechanism 3 is disposed on the flow guide member 2 and is in controlled communication with the flow guide cavity S2. It is used to collect and dilute the gaseous leakage medium in the flow guide cavity S2. The second dilution mechanism 4 is disposed on the flow guide member 2 and is in controlled communication with the flow guide cavity S2. It is used to collect and dilute the liquid leakage medium in the flow guide cavity S2.

[0038] The control mechanism 5 is connected to the first dilution mechanism 3 and the second dilution mechanism 4, and is configured to control the operation of the first dilution mechanism 3 and the second dilution mechanism 4 according to the temperature inside the guide cavity S2.

[0039] In the storage device 100 of this application, the control mechanism 5 can determine whether the leaking medium in the flow guiding cavity S2 of the flow guiding member 2 is a gaseous leaking medium or a liquid leaking medium based on the temperature inside the flow guiding cavity S2, and can automatically switch the operation of the first dilution mechanism 3 and the second dilution mechanism 4, so that the first dilution mechanism 3 and the second dilution mechanism 4 can provide timely and targeted treatment for accidental leakage of the medium in the storage device 100, thereby avoiding the safety control blind spot caused by the phase transition from liquid to gas after the medium leaks, and greatly improving the leakage treatment efficiency and the safety of the medium during storage and transportation.

[0040] In some embodiments, the flow guiding member 2 may be made of a low-temperature resistant alloy material, the wall thickness of the flow guiding cavity S2 may be 8mm, and the flow guiding cavity S2 may be designed as a cylindrical closed cavity structure.

[0041] Please see Figure 1 The flow guiding member 2 extends along the first direction L1 and has a closed end and an open end. The open end is located on the outside of a portion of the storage tank 1 and is sealed to the storage tank 1. Specifically, the open end of the flow guiding member 2 can be bolted to that portion of the storage tank 1 using a fluororubber sealing gasket. The other end of the flow guiding member 2 is a closed end, thus forming a sealed leakage medium collection space together with the storage tank 1, which can effectively prevent the leakage medium from spreading to the external environment.

[0042] In some embodiments, please refer to Figure 1 A third control valve 6 is connected to the portion of the storage tank 1 that forms a flow guide cavity S2 with the flow guide member 2. The third control valve 6 is located inside the flow guide cavity S2, and the inner diameter of the flow guide member 2 is larger than the outer diameter of the third control valve 6.

[0043] Here, since the third control valve 6 is a critical leakage area in the storage device 100, the flow guiding member 2 is set to cover this area, which can quickly and effectively deal with the leakage medium in this area, further improving the leakage handling efficiency and the safety of the target medium during storage and transportation.

[0044] In some embodiments, please refer to Figure 1 The first dilution mechanism 3 may include a first dilution tank 31, a first guide pipe 32, a first control valve 33, and an air extraction component 34.

[0045] The first dilution tank 31 is filled with an inert gas, which can dilute any leaked medium entering the first dilution tank 31. Specifically, the inert gas can be, but is not limited to, argon. For example, the volume of the first dilution tank 31 can be 50L, filled with argon gas of 99.99% purity.

[0046] To ensure the safety and stability of the dilution process, a pressure monitoring valve (with a range of 0-1.6MPa) and an exhaust valve can be installed on the first dilution tank 31 to realize real-time monitoring and adjustment of the pressure inside the tank, so as to ensure that the pressure inside the tank is stable within the safe pressure range.

[0047] The first guide pipe 32 connects the guide member 2 to the first dilution tank 31. The first control valve 33 and the extraction member 34 are both mounted on the first guide pipe 32. Specifically, the first control valve 33 can be, but is not limited to, a low-temperature resistant electromagnetic electric valve, and the extraction member 34 can be an extraction fan, which can be a low-temperature resistant explosion-proof axial flow fan structure.

[0048] The first control valve 33 and the suction component 34 are connected to the control mechanism 5. The control mechanism 5 can control the first control valve 33 to open or close according to the temperature in the guide cavity S2. When the first control valve 33 is opened, the first guide pipe 32 connects the guide cavity S2 of the guide component 2 with the first dilution tank 31. Under the control of the control mechanism 5, the suction component 34 can pump the gaseous leaked medium in the guide cavity S2 to the first dilution tank 31 for dilution. When the first control valve 33 is closed, the connection between the guide cavity S2 and the first dilution tank 31 is disconnected, and the control mechanism 5 controls the suction component 34 to stop pumping.

[0049] In this embodiment, based on the arrangement of the first guide pipe 32 and the air extraction component 34, the gaseous leaking medium in the guide component 2 can be actively transported to the first dilution tank 31 through active diversion, thereby improving the diversion efficiency of the leaking medium.

[0050] Figure 2 This is a schematic diagram of the structure of the air extraction component of the storage device according to an embodiment of this application. Please refer to... Figure 2 The extraction component 34 may include a housing 341, blades 342, a rotating shaft 343, a flow guiding component 344, and a motor (not shown). The housing 341 is fixedly mounted on the flow guiding component 2. The flow guiding component 344 is installed inside the housing 341 and forms a flow guiding channel. The blades 342 are installed inside the flow guiding channel of the flow guiding component 344, and the blades 342 are connected to the motor via the rotating shaft 343. Specifically, the rated power of the extraction component 34 can be 500W, the extraction rate can be 10m³ / h, and it can adapt to the operating temperature range of -260℃ to 50℃, meeting the usage requirements of target medium (such as liquid hydrogen) leakage scenarios.

[0051] In some embodiments, please refer to Figure 1 The first dilution mechanism 3 also includes a first check valve 35, which is disposed on the portion of the first guide pipe 32 located between the suction member 34 and the first dilution tank 31. The first check valve 35 is configured to allow gaseous leakage medium to flow unidirectionally from the suction member 34 side to the first dilution tank 31 side.

[0052] Here, based on the setting of the first check valve 35, the backflow of the leaked medium and the overflow of inert gas in the first dilution tank 31 can be avoided, thus preventing secondary risks and further improving the safety and reliability of leak handling.

[0053] In some embodiments, please refer to Figure 1 The second dilution mechanism 4 may include a second dilution tank 41, a second guide pipe 42, a second control valve 43, and a flow guiding component 44.

[0054] The second dilution tank 41 is filled with an inert gas, which can dilute any leaked medium entering the tank. Specifically, the inert gas can be, but is not limited to, argon. For example, the second dilution tank 41 may have a volume of 100L and be filled with argon gas of 99.99% purity.

[0055] To ensure the safety and stability of the dilution process, a pressure monitoring valve (range 0-1.6MPa) and an exhaust valve can also be installed on the second dilution tank 41 to realize real-time monitoring and adjustment of the pressure inside the tank, so as to ensure that the pressure inside the tank is stable within the safe pressure range.

[0056] The second guide pipe 42 connects the guide member 2 and the second dilution tank 41, and the second control valve 43 is disposed on the second guide pipe 42. The second control valve 43 is disposed on the second guide pipe 42 and connected to the control mechanism 5. The second control valve 43 can be a low-temperature resistant electromagnetic electric valve. The flow guiding member 44 is fixedly disposed in the guide member 2 and has a flow channel A, which communicates with the second guide pipe 42.

[0057] The control mechanism 5 can control the second control valve 43 to open or close according to the temperature inside the guide cavity S2. When the second control valve 43 is opened, the second guide pipe 42 connects the guide cavity S2 of the guide member 2 with the second dilution tank 41. Under the guidance of the guide member 44, the liquid leakage medium in the guide cavity S2 can be transported to the second dilution tank 41 for dilution via the second guide pipe 42. When the second control valve 43 is closed, the connection between the guide cavity S2 and the second dilution tank 41 is disconnected, and the liquid leakage medium in the guide cavity S2 stops being transported.

[0058] In this embodiment, based on the arrangement of the second guide pipe 42 and the diversion component 44, the liquid leakage medium in the guide component 2 can also be actively transported to the second dilution tank 41 through active diversion, thereby improving the diversion efficiency of the leakage medium.

[0059] In some embodiments, please refer to Figure 1 The second dilution mechanism 4 may further include a second check valve 45, which is disposed on the portion of the second guide pipe 42 located between the second control valve 43 and the second dilution tank 41. The second check valve 45 is configured to allow unidirectional flow of the leaking liquid medium from the second control valve 43 side to the second dilution tank 41 side.

[0060] Here, based on the setting of the second check valve 45, the backflow of the leaked medium and the overflow of inert gas in the second dilution tank 41 can be avoided, thus preventing secondary risks and further improving the safety and reliability of leak handling.

[0061] In some embodiments, please refer to Figure 1The flow guiding member 2 extends along the first direction L1 and has a closed end and an open end, with the open end being sealed to the storage tank 1. The flow guiding member 2 is provided with a first outlet B1 and a second outlet B2 that are arranged opposite to each other along the second direction L2. Along the second direction L2, the first outlet B1 is located on the upper side of the flow guiding member 2, and the second outlet B2 is located on the lower side of the flow guiding member 2. The confluence channel A is connected to the second flow guiding pipe 42 via the second outlet B2.

[0062] When the second control valve 43 is opened in a controlled manner, the liquid leakage medium in the guide chamber S2 can be automatically introduced into the second dilution tank 41 through the confluence channel A, the second outlet B2, and the second guide pipe 42 under the action of the liquid leakage medium's own gravity.

[0063] In some embodiments, please refer to Figure 1 Along the second direction L2, the confluence channel A is formed into a funnel-shaped structure that is wider at the top and narrower at the bottom. This can increase the flow velocity of the liquid leakage medium in the confluence channel A, thereby improving the flow conduction efficiency of the leakage medium.

[0064] In some embodiments, the inclination angle of the inner wall of the manifold A can be 30°-60°. The inclination angle of the inner wall of the manifold A refers to the angle between the inner wall surface of the manifold A and the first direction L1. For example, the inclination angle of the inner wall of the manifold A can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.

[0065] Setting the inclination angle of the inner wall of the manifold A within the above range can effectively avoid incomplete dilution of the leaking medium due to excessive flow velocity, and low dilution efficiency due to insufficient flow velocity.

[0066] In some embodiments, the control mechanism 5 may include a temperature sensor 51 and a controller 52. The temperature sensor 51 is disposed on the flow guide member 2 and located in the flow guide cavity S2, and is used to collect the temperature in the flow guide cavity S2 in real time. The controller 52 is connected to the temperature sensor 51, the first dilution mechanism 3 and the second dilution mechanism 4, and is used to switch the control of the first dilution mechanism 3 and the second dilution mechanism 4 according to the temperature signal sent by the temperature sensor 51.

[0067] The controller 52 is configured to operate the first dilution mechanism 3 when the temperature detected by the temperature sensor 5 within the flow channel S2 is equal to or greater than the vaporization temperature of the medium, and to operate the second dilution mechanism 4 when the detected temperature within the flow channel S2 is less than the vaporization temperature of the medium, thereby achieving adaptive switching of the phase state of the leaked medium. For example, when the target medium is liquid hydrogen, the vaporization temperature is -252.77℃. That is, when the temperature detected by the temperature sensor 5 within the flow channel S2 is equal to or greater than -252.77℃, the liquid hydrogen vaporizes into gaseous hydrogen; when the temperature detected by the temperature sensor 5 within the flow channel S2 is less than -252.77℃, the liquid hydrogen remains liquid hydrogen.

[0068] Specifically, the controller 52 can be a PLC controller. The controller 52 is installed on the outside of the flow guide component 2 for easy maintenance and debugging. The signal output terminal of the controller 52 is electrically connected to the first control valve 33 of the first dilution mechanism 3 and the air extraction component 34, as well as the second control valve 43 of the second dilution mechanism 4, to realize the automatic control and coordinated operation of each component.

[0069] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
