Description

Technical Field

[0001] This invention relates to the field of hydrogen energy industry, and in particular to a mobile hydrogen pressurization device. Background Technology

[0002] Hydrogen pressurization is a key link in the hydrogen energy industry chain. It is mainly used to increase low-pressure hydrogen to high-pressure hydrogen to meet the hydrogen refueling needs. Currently, hydrogen pressurization devices mainly come in three forms: liquid-driven pumps, electric piston pumps, and gas-driven pumps.

[0003] Hydraulic pumps use hydraulic oil as the power medium and require a hydraulic pump station, making them suitable only for high-flow stationary hydrogen filling stations.

[0004] Electric piston pumps achieve pressurization by driving the crankshaft piston to reciprocate at high speed with a motor. They require an explosion-proof motor, and the high-speed piston movement can easily generate particulate matter, affecting the purity of hydrogen and the overall durability of the machine.

[0005] Air-driven pumps use compressed air as power and have advantages such as intrinsic safety, moderate size and weight, no need for power supply, and simple structure, making them suitable for mobile hydrogen filling operations.

[0006] The existing technical problem is that the commonly used air-driven pump booster devices on the market rely solely on the operator's observation of the pressure gauge during use, and the air supply is cut off after the rated pressure is reached. This booster method has a low degree of automation and poor safety, and needs to be improved. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a mobile hydrogen booster device.

A hydrogen discharge check valve is installed at the outlet of the two-stage booster pump. The compressed air module includes a compressed air interface, a compressed air inlet pipe, and a compressed air outlet pipe. The compressed air interface is located on the side wall of the chassis. The compressed air inlet pipe connects the compressed air interface and the inlet of the two-stage booster pump, and a compressed air pressure gauge is installed at the connection position with the compressed air interface. The compressed air outlet pipe connects to the outlet of the two-stage booster pump. The compressed air intake pipeline includes a compressed air three-way valve and a pneumatically controlled three-way valve.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a mobile hydrogen booster device includes a chassis 1, a two-stage booster pump 2, a hydrogen output module 3, a hydrogen module 4, a compressed air module 5, and a nitrogen purging module 6.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the chassis 1 is a hollow rectangle with casters 11 on its lower end for easy transport on the ground. A two-stage booster pump 2 is installed inside the chassis 1 to compress hydrogen.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, the chassis 1 is equipped with an electrostatic grounding clamp 12, which is connected to an alarm to discharge static electricity to the ground in real time, thereby avoiding static electricity accumulation and accidents.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the front and rear sides of the chassis 1 are equipped with double-door doors 13, which facilitates the installation, maintenance and replacement of various components inside the chassis 1. The left and right sides of the chassis 1 are equipped with louvered air inlets 14 for directional air intake.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the hydrogen output module 3 is mounted on the chassis 1 and is used to connect to the gas cylinder. The hydrogen output module 3 includes a hydrogen output pipeline 31, a high-pressure hydrogen outlet 32, and a hydrogen vent 33.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a safety valve 34, a pre-filter pressure gauge 35, an output filter 36, a high-pressure output valve 37, and a post-filter pressure gauge 38 are sequentially installed on the hydrogen output pipeline 31. At the same time, the safety valve 34 is connected to the hydrogen vent port 33, and automatically releases pressure and vents when the pressure is too high.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the pressure gauge 38 after filtration is connected to the hydrogen vent 33, and a relief valve 39 is provided between the two to release pressure at the cylinder opening after the filling is completed, ensuring the safe removal of the gas cylinder.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the hydrogen module 4 includes a hydrogen interface 41, a hydrogen inlet pipe 42, and a hydrogen outlet pipe 43.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the hydrogen interface 41 is located on the side wall of the chassis 1, and a hydrogen filter 44 is connected to the rear of the hydrogen interface 41 to realize automatic hydrogen filtration.

[0031] like Figure 1 , Figure 2 , Figure 3As shown, the hydrogen inlet pipe 42 connects to the hydrogen interface 41 and the inlet of the two-stage booster pump 2. A hydrogen shut-off valve 45 and a hydrogen pressure gauge 46 are installed at the front end of the hydrogen inlet pipe 42. The hydrogen outlet pipe 43 connects to the outlet of the two-stage booster pump 2 and the front end of the hydrogen output module 3, and a hydrogen discharge check valve 47 is installed at the outlet of the two-stage booster pump 2.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the compressed air module 5 includes a compressed air interface 51, a compressed air inlet pipe 52, and a compressed air outlet pipe 53.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the compressed air interface 51 is located on the side wall of the chassis 1, and a compressed air filter 54 is connected to the rear of the compressed air interface 51 to realize automatic filtration of compressed air.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, the compressed air inlet pipe 52 is connected to the compressed air interface 51 and the inlet of the two-stage booster pump 2, and a compressed air pressure gauge 55 is installed at the connection position with the compressed air interface 51. The compressed air outlet pipe 53 is connected to the outlet of the two-stage booster pump 2.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, the compressed air intake pipeline 52 includes a compressed air three-way valve 521 and a pneumatically controlled three-way valve 522, with two pipelines between the compressed air three-way valve 521 and the pneumatically controlled three-way valve 522.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, the first pipeline is sequentially equipped with a pilot air check valve 523, a pilot air pressure reducing valve 524, a pilot air three-way valve 525, and a pilot valve 526. The pilot valve 526 is connected to the front end of the hydrogen output module 3. The second pipeline is sequentially equipped with a compressed air pressure reducing valve 527 and a compressed air speed regulating valve 528.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, the nitrogen purging module 6 includes a nitrogen interface 61 and a purging pipeline 62.

[0038] like Figure 1 , Figure 2 , Figure 3As shown, the nitrogen port 61 is located on the side wall of the chassis 1, and a nitrogen filter 63 is connected to the rear of the nitrogen port 61 to realize automatic nitrogen filtration.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, one end of the purge line 62 is connected to the nitrogen port 61, and the other end is connected to the hydrogen inlet line 42, and is located between the hydrogen shut-off valve 45 and the hydrogen pressure gauge 46. The purge line 62 is equipped with a nitrogen shut-off valve 64 and a nitrogen check valve 65 in sequence.

[0040] Before compressing hydrogen, the nitrogen shut-off valve 64 is opened to allow nitrogen to enter the hydrogen inlet pipe 42, hydrogen outlet pipe 43, and hydrogen outlet pipe 31 in sequence. This ensures that all pipes through which hydrogen can flow are filled with nitrogen and discharged outwards, replacing the oxygen in the pipes and preventing the formation of a hydrogen-oxygen mixture that could explode, thus ensuring safety.

[0041] Then, the nitrogen shut-off valve 64 is closed, and the hydrogen shut-off valve 45 is opened, allowing hydrogen to enter the two-stage booster pump 2 along the hydrogen inlet pipe 42. At the same time, the compressed air three-way valve 521 is opened, allowing compressed air to enter the two-stage booster pump 2 after passing through the compressed air pressure reducing valve 527, the compressed air speed regulating valve 528, and the pneumatic three-way valve 522, and working together to compress the hydrogen.

[0042] When the pressure at position 43 of the hydrogen outlet pipeline reaches the rated pressure, the automatic control pilot valve 526 is turned on, driving air through the pilot valve 526 into the pilot port of the pneumatic three-way valve 522, and causing the valve core to move, cutting off the pipeline of driving air flowing into the two-stage booster pump 2, causing it to stop pumping, thus realizing the function of automatically cutting off the gas supply after reaching the rated pressure. It has a high degree of automation and high safety.

[0043] The compressed hydrogen then flows along the hydrogen outlet pipe 43 to the hydrogen output module 3. At this point, the gas cylinder is connected to the high-pressure hydrogen outlet 32, and the high-pressure output valve 37 is opened while the vent valve 39 is closed, allowing the hydrogen to pass through the safety valve 34 and fill the gas cylinder. Once the gas cylinder is full of hydrogen, the high-pressure output valve 37 is closed first, and then the vent valve 39 is opened, allowing excess compressed hydrogen to be discharged through the hydrogen vent port 33.

[0044] Furthermore, when the inflation process is underway, if the hydrogen pressure in the hydrogen outlet pipe 43 exceeds a predetermined value, the safety valve 34 will automatically open, allowing the hydrogen to be depressurized and discharged through the hydrogen vent 33, thus ensuring safety during inflation.

[0045] like Figure 3As shown, a heat exchanger 7 is provided between the two-stage booster pump 2 and the hydrogen output module 3. Hydrogen is introduced into the heat exchanger 7, and the compressed air outlet pipeline 53 is connected to the cooling medium inlet of the heat exchanger 7.

[0046] After the compressed air finishes its work in the two-stage booster pump 2, the hydrogen is compressed, causing its temperature to rise, and then enters the heat exchanger 7. At the same time, the exhaust gas from the compressed air also enters the cooling medium inlet of the heat exchanger 7. The flow of compressed air cools the hydrogen, ensuring safety during the hydrogen pressurization process. Example

[0047] like Figure 4 As shown, the heat exchanger 7 includes a support frame 71, a heat exchange tube 72, and a jacket 73.

[0048] like Figure 4 , Figure 5 As shown, the heat exchange tube 72 is arranged in a serpentine shape on the support frame 71, and the jacket 73 is fitted onto the outer wall of the horizontal section of the heat exchange tube 72. A connecting pipe 74 is provided between the upper and lower jackets 73. A cooling box 8 is provided at the inlet of the lowermost jacket 73. The upper end of the cooling box 8 is connected to the jacket 73, and the lower end is the inlet of the cooling medium.

[0049] like Figure 5 As shown, a drawer frame 81 is horizontally slidably connected inside the cooling box 8, and an ice plate 82 arranged in a loofah-like pattern is embedded in the drawer frame 81. A medium inlet pipe 83 is arranged in a U-shape on the lower end face of the cooling box 8, and a drain valve 84 is provided at the bend of the medium inlet pipe 83.

[0050] When cooling the hydrogen, the hydrogen flows within the heat exchange tube 72. At this time, the drawer rack 81 is first pulled out, and then the frozen ice plate 82 is placed inside the drawer rack 81. The drawer rack 81 is then pushed back into the cooling box 8. When compressed air exhaust is introduced, the compressed air exhaust enters the cooling box 8 along the medium inlet pipe 83 and flows through the ice plate 82.

[0051] Because the ice plate 82 is shaped like a loofah, it has numerous gaps and channels, allowing the compressed air exhaust gas to be fully cooled before entering the jacket 73, flowing along the connecting pipe 74 into the numerous jackets 73, and finally being discharged into the atmosphere.

[0052] At this time, hydrogen flows along the heat exchange tube 72, and the cooled compressed air exhaust gas can be used to cool the heat exchange tube 72, achieving sufficient cooling of the hydrogen and ensuring safety during the hydrogen pressurization process. After the ice plate 82 has been used for a period of time, it can be quickly disassembled and replaced to meet the requirement of continuous cooling of hydrogen without stopping the machine. Moreover, the medium inlet pipe 83 is U-shaped, so that condensate can be accumulated in the medium inlet pipe 83 and discharged through the drain valve 84, ensuring the stable operation of the heat exchanger 7.

[0053] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
