Description
Technical Field
[0001] The utility model relates to the technical field of hydrogenation, in particular to a mobile hydrogenation system integrating production, storage and hydrogenation based on a methanol reforming hydrogen production technology. Background Art
[0002] Hailed as the "ultimate energy source of the 21st century," hydrogen is a secondary clean energy source. Highly efficient, clean, safe, and environmentally friendly, its combustion product is solely water, making it one of the cleanest energy sources. Hydrogen energy not only has widespread applications in power generation, electric vehicles, and fuel cells, but also has the potential to become a significant primary energy source.
[0003] The advantages of hydrogen energy include:
[0004] High energy and cleanliness: The calorific value of hydrogen is three times that of gasoline, and the only combustion product is water, which is pollution-free to the environment.

[0006] Flexible application: Hydrogen can be burned as fuel to produce fuel cells, or converted into a solid state as a structural material.
[0007] Hydrogen is the primary form of hydrogen energy. Hydrogen is typically stored in hydrogen tanks as high-pressure gas or high-pressure liquefied gas, and is then delivered to the user through the tanks. Existing technologies typically refuel hydrogen tanks at fixed refueling stations, and then utilize the hydrogen within. Once the hydrogen in the tank is depleted, the user must return to the refueling station for refueling. However, refueling stations are often geographically distant from users, making hydrogen energy inconvenient to use. Utility Model Content

[0030] Example 1
[0031] A mobile hydrogenation system based on methanol reforming hydrogen production technology with integrated storage and refueling, such as Figure 1 As shown, the system comprises a skid-mounted housing 1 and a control system. The skid-mounted housing 1 houses a hydrogen production system 2, a hydrogen storage system 3, and a hydrogen refueling system 5. The hydrogen production system 2 is a methanol reforming hydrogen production system. The hydrogen produced by the hydrogen production system 2 enters the hydrogen storage system 3. The hydrogen storage system 3 stores the received hydrogen in a high-pressure hydrogen storage tank and delivers the hydrogen to the hydrogen refueling system 5 according to control system instructions. The hydrogen refueling system 5 adjusts the received hydrogen to the target pressure before delivering it to the user.
[0032] The signal terminals of the hydrogen production system 2 , the hydrogen storage system 3 and the hydrogenation system 5 are respectively connected to the control system signal.
[0033] Methanol reforming to produce hydrogen is a novel and advanced technology. Its technical principle is mainly based on the high energy density, high safety and wide availability of methanol fuel. Its basic process is as follows: Figure 4 As shown, it can be divided into five steps, including fuel pretreatment, methanol steam reforming, hydrogen purification, gas low-pressure storage and carbon dioxide capture.
[0034] The present invention uses a skid-mounted housing 1 to transform the existing relatively mature methanol reforming hydrogen production system into a hydrogen production system 2, and combines it with a hydrogen storage system 3 and a hydrogenation system 5 to form an integrated hydrogenation system that integrates production, storage, and refueling. The skid-mounted housing 1 can be a conventional container-type housing or other housing that can be installed with the hydrogen production system 2, hydrogen storage system 3, and hydrogenation system 5 of the present invention. Since the skid-mounted housing 1 can be conveniently transported, the integrated hydrogenation system of the present invention can also be conveniently transported, realizing mobile integrated hydrogenation. Therefore, the mobile integrated hydrogenation system for production, storage, and refueling based on methanol reforming hydrogen production technology of the present invention can be transported and installed in a hydrogen location or a suitable location close to a hydrogen use location as needed, effectively solving the problem of inconvenience in using hydrogen caused by the fixed distance of the existing hydrogenation station, which is not necessarily close to the hydrogen use location.
[0035] Example 2
[0036] Based on the methanol reforming hydrogen production technology of Example 1, the integrated mobile hydrogenation system for production, storage and addition is as follows: Figure 1As shown, the hydrogen storage system 3 is installed on the top inside the skid-mounted box 1, and the hydrogen refueling system 5 is installed on the bottom inside the skid-mounted box 1. The hydrogen refueling system 5 is installed on the side outside the skid-mounted box 1.
[0037] Generally speaking, the mass of the hydrogenation system 5 will be greater than that of the hydrogen storage system 3. This setting can balance the center of gravity position in the skid-mounted box 1 where the hydrogen production system 2, the hydrogen storage system 3, and the hydrogenation system 5 are installed, so that the center of gravity position of the skid-mounted box 1 is more biased downward, thereby improving the overall stability of the present invention and avoiding problems such as transportation difficulties or excessive transportation risks caused by an excessively high center of gravity during transportation.
[0038] Example 3
[0039] Based on the methanol reforming hydrogen production technology of Example 1, the integrated mobile hydrogenation system for production, storage and addition is as follows: Figure 2 As shown, the hydrogen storage system 3 includes: a first compressor 301 and a high-pressure hydrogen storage tank 302. The air inlet end of the first compressor 301 is connected to the hydrogen output end of the hydrogen production system 2, and the air outlet end is connected to the high-pressure hydrogen storage tank 302 through a first air pipeline. A first pressure transmitter 304 is installed on the first air pipeline near the first compressor 301, and a first safety valve 303 is connected between the first pressure transmitter 304 and the first compressor 301 through a second air pipeline. A second pressure transmitter 307 is installed on the first air pipeline near the high-pressure hydrogen storage tank 302, and a second safety valve 306 is connected between the second pressure transmitter 307 and the high-pressure hydrogen storage tank 302 through a third air pipeline. The first compressor 301 can be a diaphragm compressor as needed.
[0040] The signal output terminals of the first pressure transmitter 304 and the second pressure transmitter 307 are connected to the control system signal. The control terminal of the first compressor 301 is connected to the control system signal.
[0041] Since the hydrogen pressure produced by the hydrogen production system 2 is generally lower than the hydrogen storage pressure of the high-pressure hydrogen storage tank 302, the hydrogen pressure produced by the hydrogen production system 2 needs to be increased by the first compressor 301 and then flushed into the high-pressure hydrogen storage tank 302 for storage.
[0042] The first pressure transmitter 304 detects the pressure output by the first compressor 301 in real time and sends it to the control system. Based on the pressure data received from the first pressure transmitter 304, the control system determines whether the first compressor 301 is operating normally or whether the output pressure value meets expectations. If the first compressor 301 outputs abnormal pressure, the control system will issue a corresponding alarm or perform safety processing. The second pressure transmitter 307 detects the pressure at the front end of the high-pressure hydrogen storage tank 302 in real time and sends it to the control system. Based on the pressure data received from the second pressure transmitter 307, the control system determines whether the high-pressure hydrogen storage tank 302 is within the safety threshold and issues a corresponding alarm or performs safety processing if it is determined to be unsafe.
[0043] When the first compressor 301 stops working or the high-pressure hydrogen storage tank 302 is full, excess hydrogen in the first gas pipeline is discharged through the first safety valve 303 or the second safety valve 306 .
[0044] According to one embodiment of the present invention, Figure 2 As shown, a first on-off valve 305 and a first ball valve 308 are installed on the first gas pipeline between the first pressure transmitter 304 and the third gas pipeline. A second ball valve 309 is installed on the first gas pipeline between the high-pressure hydrogen storage tank 302 and the third gas pipeline. A vent line is installed on the first gas pipeline between the second pressure transmitter 307 and the third gas pipeline. The vent line is equipped with a third on-off valve 310 and a first stop valve 311 in parallel.
[0045] The first switch valve 305 and the third switch valve 310 may be electrically controlled pneumatic valves in signal communication with the control system.
[0046] The first on-off valve 305 is automatically opened when the first compressor 301 is turned on and closed when it is turned off. The first ball valve 308 is manually controlled to be on / off. This ensures that the first compressor 301 is connected to the first gas pipeline when it is turned on and is blocked when it is turned off. This prevents the hydrogen in the high-pressure hydrogen storage tank 302 from being reversely discharged (leaked) when the first compressor 301 is turned off, impacting the first compressor 301 and then reversely rushing into the hydrogen production system 2, damaging the equipment and easily causing large-scale hydrogen leakage.
[0047] The installed second ball valve 309 can manually control the connection state between the high-pressure hydrogen storage tank 302 and the first gas pipeline, thereby adding a defensive measure to prevent the reverse output (leakage) of the hydrogen in the high-pressure hydrogen storage tank 302.
[0048] The installed third switch valve 310 can be controlled by the control system to perform automatic venting and pressure relief actions, and the first stop valve 311 can be manually vented and pressure relief actions.
[0049] According to one embodiment of the present invention, Figure 1and Figure 2 As shown, the air inlet of the first compressor 301 is connected to the hydrogen output of the hydrogen production system 2 via the first buffer tank 8. Since the hydrogen production of the hydrogen production system 2 may fluctuate, the buffering effect of the first buffer tank 8 can effectively prevent the first compressor 301 from being unloaded or overloaded due to unstable hydrogen input flow, thereby increasing the service life of the first compressor 301.
[0050] Example 4
[0051] Based on the methanol reforming hydrogen production technology of Example 1, the integrated mobile hydrogenation system for production, storage and addition is as follows: Figure 3 As shown, the hydrogenation system 5 includes a hydrogenation pipeline connected to the hydrogen output end of the hydrogen storage system 3. The hydrogenation pipeline is provided with the following devices in sequence along the direction of hydrogen flow: a sampling valve 502, a third pressure transmitter 505, a second on-off valve 506, a flow meter 507, a pressure regulating valve 508, a fourth pressure transmitter 510, a pull-off valve 509, and a hydrogenation mechanism 504. The hydrogenation pipeline is connected to a third safety valve 503 via a fourth gas pipeline near the third pressure transmitter 505 along the direction of hydrogen flow, and is connected to a fourth safety valve 511 via a fifth gas pipeline near the fourth pressure transmitter 510 along the direction of hydrogen flow.
[0052] The signal output ends of the third pressure transmitter 505 and the fourth pressure transmitter 510 are connected to the control system signal.
[0053] When the control system receives a hydrogenation request, it controls the hydrogen storage system 3 to release hydrogen into the hydrogenation pipeline. At this point, the sampling valve 502 can sample as needed to determine whether the output hydrogen concentration meets the requirements. The third pressure transmitter 505 is used to collect the hydrogen pressure output by the hydrogen storage system 3 in real time and transmit it to the control system. The control system determines whether the hydrogen output by the hydrogen storage system 3 is normal based on the information received from the third pressure transmitter 505. The flow meter 507 collects the hydrogen flow rate within the hydrogenation pipeline in real time and transmits it to the control system. The control system determines whether the current output hydrogen flow rate meets the requirements based on the information received from the flow meter 507. The pressure regulating valve 508 is used to adjust the hydrogen pressure output by the hydrogenation pipeline, allowing the hydrogenation system 5 to output the appropriate hydrogen pressure according to the different hydrogen users. The fourth pressure transmitter 510 collects the hydrogen pressure output by the pressure regulating valve 508 in real time and transmits it to the control system. The control system determines whether the hydrogen pressure output by the hydrogen storage system 3 meets the requirements based on the information received from the fourth pressure transmitter 510. The pull-off valve 509 is used to disconnect the hydrogenation pipeline from the hydrogenation mechanism 504 when an unexpected situation is discovered during the hydrogenation process, such as a fire or abnormal hydrogen leakage, to prevent the disaster from expanding. The hydrogenation mechanism 504 is used to add hydrogen to hydrogen-using equipment.
[0054] According to one embodiment of the present invention, Figure 1 and Figure 3 As shown, the hydrogenation pipeline is connected to the hydrogen output end of the hydrogen storage system 3 via a second buffer tank 4. The hydrogen pressure output by the hydrogen storage system 3 may fluctuate significantly at the output front end or the output end. The addition of a second buffer tank 4 can effectively prevent the hydrogen pressure fluctuations output by the hydrogen storage system 3 from interfering with the hydrogenation process.
[0055] According to one embodiment of the present invention, Figure 3 As shown, the hydrogen refueling pipeline is connected to the hydrogen output terminal of the hydrogen storage system 3 via a second compressor 501. The control terminal of the second compressor 501 is connected to the control system signal. In some hydrogen-using applications, the pressure of the high-pressure hydrogen storage tank of the hydrogen-using equipment may be higher than the pressure of the hydrogen storage system 3 of the present invention. Therefore, the second compressor 501 is required to perform a secondary pressurization on the hydrogen output from the hydrogen storage system 3 to ensure that the output hydrogen pressure meets the hydrogen refueling requirements of the hydrogen-using equipment.
[0056] Example 5
[0057] Based on the methanol reforming hydrogen production technology of Example 1, the integrated mobile hydrogenation system for production, storage and addition is as follows: Figure 1 As shown, an exhaust fan 7 is provided on the side wall of the skid-mounted box 1, and several hydrogen concentration sensors are installed at different positions inside. The exhaust fan 7 and the several hydrogen concentration sensors are all connected to the control system signal.
[0058] At this time, several hydrogen concentration sensors detect the hydrogen concentration in key parts of the skid-mounted box 1 in real time to determine whether a hydrogen leakage problem occurs. When the hydrogen concentration in the skid-mounted box 1 exceeds the standard, the control system controls the exhaust fan 7 to start and discharge the hydrogen in the skid-mounted box 1 in time to avoid the risk of explosion.
[0059] According to the above-described embodiment of the integrated mobile hydrogenation system for production, storage, and refueling based on methanol reforming hydrogen production technology, flame arresters 6 are installed at locations where hydrogen is discharged. For example, flame arresters 6 are installed at the exhaust end of the safety valve and the air inlet end of the exhaust fan 7. This effectively reduces the possibility of flashback entering the hydrogen production system or storage system, resulting in catastrophic accidents.
[0060] With the above-described preferred embodiments of the present invention as a guide, those skilled in the art will readily be able to make various changes and modifications without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the contents of the specification and must be determined in accordance with the scope of the claims.
