Description

Technical Field

[0001] The utility model relates to the technical field of ultra-high pressure hydrogenation systems, in particular to a multi-functional combined ultra-high pressure hydrogenation system. Background Technique

[0002] Hydrogen energy is a secondary energy source, which is produced by using other energy sources through certain methods, unlike coal, oil, and natural gas that can be directly mined. Hydrogen energy is a recognized clean energy source and is emerging as a low-carbon and zero-carbon energy source. When using hydrogen energy, a hydrogen filling machine is generally required to add hydrogen energy for use;

[0003] For example, the publication number is CN217843499U, a micro ultra-high pressure hydrogen filling machine, specifically related to the field of hydrogen energy, including a hydrogen filling machine. An explosion-proof mechanism is arranged on one side of the hydrogen filling machine. The explosion-proof mechanism includes a movable groove, a movable rod, a housing, a motor, a rotating shaft, a fan blade, a dust-proof net, a fixing bolt, and a gas concentration sensor. A movable groove is formed on the outer wall surface of the hydrogen filling machine;

[0004] For the above-mentioned micro ultra-high pressure hydrogen filling machine in the application, when it is working, the movable rod can be first inserted into the movable groove. Under the interaction of the movable rod and the movable groove, it can facilitate the installation of the housing. And when hydrogen leaks inside the hydrogen filling machine, the gas concentration sensor will sense it, and then send a command to the motor to turn on the motor, drive the rotating shaft to rotate, and the rotating shaft drives the fan blade to rotate, which can disperse the gas to avoid the leakage of hydrogen gas gathering together and causing safety hazards such as explosion. However, when the existing ultra-high pressure hydrogenation unit is in use, when the 45Mpa compressor fails, the 90Mpa compressor cannot be directly substituted, which is likely to damage the components in the 45Mpa unit and affect the hydrogenation efficiency of the 45Mpa unit. Therefore, there is an urgent need in the market to develop a multi-functional combined ultra-high pressure hydrogenation system to help people solve existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-functional combined ultra-high pressure hydrogenation system to solve the problem that when the 45Mpa compressor fails during the use of the ultra-high pressure hydrogenation unit, the 90Mpa compressor cannot be directly substituted, which is likely to damage the components in the 45Mpa unit and affect the hydrogenation efficiency as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: a multifunctional combined ultra-high pressure hydrogenation system, including a 90Mpa hydrogenation unit and a 45Mpa hydrogenation unit. The 90Mpa hydrogenation unit includes a first compressor and a first hydrogenation unit pipeline. The 45Mpa hydrogenation unit includes a second compressor and a second hydrogenation unit pipeline. The output pressure of the first compressor is 90Mpa, and the output pressure of the second compressor is 45Mpa. A first joint is provided on the first compressor, a second outlet pipe is installed on the first joint, a second electric valve is installed on the second outlet pipe, the output end of the second outlet pipe is communicated with a pressure relief tank, a third electric valve is provided at the output end of the pressure relief tank, a second hydrogen transmission pipe is connected between the second compressor and the second hydrogenation unit pipeline, and a second connection pipe for communication is provided between the output end of the pressure relief tank and the second hydrogen transmission pipe.

[0007] Through the above technical solutions, the output pressure of the first compressor is first reduced by the pressure relief tank, so that its gas transmission pressure conforms to the operating range of the 45Mpa compression unit, avoiding damage to the components in the 45Mpa unit. After pressure regulation, the third electric valve at the output end of the pressure relief tank is opened, so that the 90Mpa compressor can supply gas for filling through the 45Mpa unit. Thus, when the 45Mpa unit fails, the 90Mpa unit can still be used for hydrogen filling, avoiding interruption of the hydrogenation work and improving the hydrogenation efficiency.

[0008] In a preferred example of the present utility model, it can be further configured that: hydrogen inlet ends are provided on both the first compressor and the second compressor.

[0009] In a preferred example of the present utility model, it can be further configured that: a first connection pipe is connected between the second outlet pipe and the pressure relief tank, and a pressure gauge is provided on the pressure relief tank.

[0010] In a preferred example of the present utility model, it can be further configured that: a third outlet pipe is installed at the output end of the pressure relief tank, and the third electric valve is installed on the third outlet pipe.

[0011] In a preferred example of the present utility model, it can be further configured that: a second joint is provided on the second compressor, a fourth outlet pipe is installed on the second joint, the output end of the fourth outlet pipe is connected to the second hydrogen transmission pipe, and a fourth electric valve is installed on the fourth outlet pipe.

[0012] In a preferred example of the present utility model, it can be further configured that: a first outlet pipe is installed on the first joint, a first electric valve is installed on the first outlet pipe, and a first hydrogen transmission pipe is connected between the output end of the first outlet pipe and the first hydrogenation unit pipeline.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] This utility model first reduces the output pressure of the first compressor through a pressure relief tank, so that its gas transmission pressure conforms to the operating range of the 45Mpa compressor unit, avoiding damage to the components in the 45Mpa unit. After pressure regulation, the third electric valve at the output end of the pressure relief tank is opened, so that the 90Mpa compressor can supply gas for filling through the 45Mpa unit. Thus, when the 45Mpa unit fails, the 90Mpa unit can still be used for hydrogen filling, avoiding the interruption of the hydrogenation work and improving the hydrogenation efficiency.
