Description

Technical Field

[0001] The utility model belongs to the technical field of solid-state gas storage, and in particular relates to a solid-state hydrogen storage tank with circulating heat exchange. Background Art

[0002] Solid-state hydrogen storage tanks use solid-state hydrogen storage technology to chemically react hydrogen with one or more hydrogen storage materials (such as metals, alloys, nanomaterials, etc.) under certain conditions to generate hydrides. This hydride is solid at room temperature, so it can be stored in a gas tank. When hydrogen is needed, the hydride is decomposed to release hydrogen by heating or reducing pressure.

[0003] At present, solid hydrides can be stored in hydrogen storage tanks, but some solid storage tanks do not fully decompose and release hydrides because the hydrogen needs to be released by heating and reducing pressure during the conversion process. Therefore, we propose a solid hydrogen storage tank with circulating heat exchange. Utility Model Content

[0004] The purpose of the utility model is to provide a solid-state hydrogen storage tank with a circulating heat exchange, which is opened by toggling the input pipe through the valve ring, so that the heat exchange liquid is introduced into the S tube two through the input pipe, and at the same time, the spiral tubes connected according to the area division on the outer surface of the S tube two are diverted. Since the spiral tubes are in a spiral shape, they can fully contact the hydride to react and generate gas. Then, the bottom of the spiral tube is connected with the S tube one, and the S tube one is connected with the output port to discharge the heat exchange liquid. The circulating setting can fully allow the reaction to proceed, thereby solving the problem that some solid-state storage tubes do not fully decompose and release the hydride because the hydrogen needs to be released by heating and reducing pressure during the conversion process.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a solid-state hydrogen storage tank with circulating heat exchange, comprising a hydrogen storage tank, the outer surface of which is respectively in contact with a stabilizing ring and a support platform, and the bottom of the support platform is fixedly connected with a support leg;

[0007] The outer surface of the support platform contacts the inner wall of the stabilizing ring. An exhaust valve, an input pipe and a sealing cover are respectively arranged above the hydrogen storage tank. The outer surface of the input pipe is fixedly connected with a valve ring.

[0008] Furthermore, an adjusting handle is rotatably connected to the front of the valve ring, an S-tube 2 is fixedly connected to the bottom of the input pipe, and a spiral tube is fixedly connected to the bottom of the S-tube 2.

[0009] Furthermore, an S-tube 1 is fixedly connected to the bottom of the spiral tube, an output port is fixedly connected to the front of the S-tube 1, the output port is fixedly connected to the inner wall of the hydrogen storage tank, and an air outlet pipe is fixedly connected to the back of the hydrogen storage tank.

[0010] Furthermore, the inner wall of the exhaust valve contacts with a rubber plug, the top of the rubber plug is respectively fixedly connected with a spring and an adjusting rod material, the outer surface of the adjusting rod material is slidably connected with the inner wall of the exhaust valve, and the top of the spring is fixedly connected with a deflation plate.

[0011] Furthermore, the outer surface of the air release plate is fixedly connected to the inner wall of the exhaust valve, a plurality of slots are opened on the top of the air release plate, an exhaust cover is fixedly connected to the top of the exhaust valve, a handle is fixedly connected to the top of the sealing cover, a flange ring 1 is threadedly connected to the inner wall of the sealing cover, a flange ring 2 is fixedly connected to the bottom of the flange ring 1 by screws, and the bottom of the flange ring 2 is fixedly connected to the top of the hydrogen storage tank.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model sets an input pipe, specifically, the input pipe is opened by toggling the valve ring, so that the heat exchange liquid is introduced into the S tube 2 through the input pipe, and the spiral tube connected according to the area of ​​the outer surface of the S tube 2 is split. Since the spiral tube is in a spiral shape, it can fully contact the hydride to react and generate gas. Then, the bottom of the spiral tube is connected with the S tube 1, and the S tube 1 is connected to the output port to discharge the heat exchange liquid. The reaction can be fully carried out through the setting of the circulation.

[0014] 2. The utility model provides an exhaust valve, specifically an exhaust valve provided according to the pressure level to which the hydrogen storage tank is subjected. When the air pressure exceeds the bearing range of the exhaust valve, the rubber plug will be pushed so that the rubber plug squeezes the spring, so that the rubber plug is separated from the contact with the inner wall of the exhaust valve. At the same time, the air pressure is released through the exhaust valve pipeline to prevent the hydrogen storage tank from being damaged due to excess air pressure, thereby causing accidents, thereby improving the safety of the hydrogen storage tank.
