Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy application, and in particular to an intelligent hydrogenation system and method for a hydrogenation station. Background Art

[0002] A hydrogen refueling station is a specialized infrastructure used to refill hydrogen tanks for hydrogen fuel cell vehicles, hydrogen internal combustion engine vehicles, or hydrogen / natural gas hybrid vehicles. Unlike traditional gas stations, hydrogen refueling stations store and deliver hydrogen at high pressure or low temperatures to meet the refueling needs of hydrogen fuel cell vehicles.

[0003] A hydrogen refueling station primarily consists of a hydrogen production system, compression system, storage system, filling system, and control system. Hydrogen can be transported to the station via tube trailers, liquid hydrogen tankers, pipelines, and other means, or it can be generated within the station's hydrogen production equipment. After being pressurized by a compressor, the hydrogen is stored in high-pressure tanks within the station. When hydrogen refueling is needed, the filling system rapidly transfers the hydrogen to the on-board hydrogen storage tank, driven by the high pressure differential between the station's fixed high-pressure tank and the on-board hydrogen storage tank.

[0004] The hydrogen refueled at a hydrogen refueling station can be in gaseous or liquid form. Currently, high-pressure gaseous hydrogen refueling stations are the mainstream, with mature technology and wide application. Liquid hydrogen refueling stations are gradually gaining attention due to their high hydrogen storage density and rapid refueling capabilities, and are particularly suitable for heavy-duty vehicles and large-scale hydrogen refueling needs. When liquid hydrogen leaks into a room temperature environment, it will quickly absorb heat from the surrounding environment and vaporize. If the leakage rate is lower than the instantaneous vaporization rate, the liquid hydrogen will quickly vaporize near the leak port. If the leakage rate is higher than the instantaneous vaporization rate, some liquid hydrogen will accumulate on the solid surface near the leak port and expand into a liquid pool. The hydrogen concentration detector cannot detect it immediately, and hydrogen refueling stations mostly rely on natural ventilation. Therefore, when the leakage rate is faster, the internal hydrogen concentration will rise rapidly within a period of time, posing certain safety risks. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-15 The present invention provides a technical solution: an intelligent hydrogenation system for a hydrogenation station, including a hydrogenation machine 1, the hydrogenation machine 1 is equipped with a liquid hydrogen transmission pipeline 2 for transmitting liquid hydrogen, the inlet end of the liquid hydrogen transmission pipeline 2 is externally connected to a liquid hydrogen storage tank for storing liquid hydrogen, the outlet end of the liquid hydrogen transmission pipeline 2 is connected to a hydrogenation gun 3, the hydrogenation gun 3 is used to connect to the gas tank of a hydrogen-powered vehicle, and a sensing mechanism 4 is provided on the lower side of the liquid hydrogen transmission pipeline 2 for receiving liquid dripping from the liquid hydrogen transmission pipeline 2 for analysis and collection.

[0036] like Figure 3 、 Figure 4As shown, the sensing mechanism 4 includes a placement box 41, the upper side of the placement box 41 is open, and several receiving components 42 are closely arranged in the placement box 41. The receiving component 42 includes a first cylinder 421, and a first receiving plate 422 is fixed to the driving end of the first cylinder 421. The surface of the first receiving plate 422 is covered with a pressure sensing module, and a spring 423 is connected to the lower side of the first receiving plate 422. The other end of the spring 423 is connected to the second receiving plate 424, and a third receiving plate 425 is fixed to the fixed end surface of the first cylinder 421.

[0037] The supplementary explanation based on the above structure is as follows: Figure 4 As shown, the receiving component 42 has three modes. The first is the conventional receiving mode. At this time, the first receiving plate 422, the second receiving plate 424 and the third receiving plate 425 of each receiving component 42 correspond to each other, forming three planar layers, namely the sensing layer 43, the water collection layer 44 and the hydrogen collection layer 45, and the surface height of the first receiving plate 422 is lower than the surface height of the placement box 41.

[0038] Further, such as Figure 5 As shown, the second mode is the liquid water receiving mode. At this time, liquid water drips on the liquid hydrogen delivery pipeline 2 and is locked to the specific receiving component 42 through the pressure sensing module. The corresponding first cylinder 421 controls the first receiving plate 422 to move down to the same height as the second receiving plate 424 of other receiving components 42. At this time, the first receiving plate 422 is located in the water collecting layer 44, and the dripping liquid water is confined in the water collecting layer 44.

[0039] Furthermore, Figure 6 As shown, the third mode is the liquid hydrogen receiving mode. At this time, liquid hydrogen drips on the liquid hydrogen delivery pipeline 2 and is locked to the specific receiving component 42 through the pressure sensing module. The corresponding first cylinder 421 controls the second receiving plate 424 to move down to a state of being in contact with the third receiving plate 425. At the same time, the first receiving plate 422 is located in the hydrogen collection layer 45, and the dripping liquid hydrogen is confined in the hydrogen collection layer 45.

[0040] Optionally, corresponding magnetic blocks and adsorption blocks are provided on the sides of the first receiving plate 422 , the second receiving plate 424 and the third receiving plate 425 to strengthen the connection.

[0041] A water outlet 411 is provided on one side of the placement box 41 corresponding to the water collecting layer 44, and a hydrogen outlet 412 is provided on the other side of the placement box 41 corresponding to the hydrogen collecting layer 45. Figure 7 As shown, when the receiving component 42 detects a liquid signal and moves to the corresponding plane layer, in order to better drain the liquid to the corresponding outlet, the corresponding receiving plates of the remaining receiving components 42 form a stepped slope, and the low position of the gradient faces the corresponding outlet, thereby helping the liquid to be discharged smoothly.

[0042] like Figure 8 、 Figure 9 As shown, a drain tank 5 is provided on one side of the hydrogenator 1, and the drain tank 5 is provided with a first outlet 51 and a second outlet 52 corresponding to the water outlet 411 and the hydrogen outlet 412 respectively. A partition plate 53 is provided in the drain tank 5, and one side of the partition plate 53 is connected to the second cylinder 54. A slide rail 55 is provided on the inner wall of the drain tank 5, and the partition plate 53 slides with the slide rail 55. The side of the partition plate 53 facing the first outlet 51 and the second outlet 52 is set as a liquid outlet area 56, and the side of the partition plate 53 facing the second cylinder 54 is set as an air outlet area 57.

[0043] like Figure 10 As shown, the partition plate 53 is provided with a pull plate 531 in conjunction with the first outlet 51. One end of the pull plate 531 slides with the drainage box 5, and the other end of the pull plate 531 is provided with a window 532 corresponding to the first outlet 51. The partition plate 53 is provided with a sealing plate 533 in conjunction with the second outlet 52.

[0044] Preferably, an accordion cover 58 is provided on the upper side of the liquid outlet area 56, and the accordion cover 58 is respectively connected to the inner wall of the drainage box 5 and the partition plate 53, for sealing the liquid outlet area 56 from the outside world. A confluence area 59 is provided on the other side of the drainage box 5 relative to the first outlet 51, and the confluence area 59 is externally connected to an exhaust device.

[0045] The supplementary explanation based on the above structure is as follows: Figure 11 、 Figure 12 As shown, different opening and closing states of the first outlet 51 and the second outlet 52 are achieved according to the moving position of the partition plate 53. When the window 532 corresponds to the first outlet 51, the sealing plate 533 closes the second outlet 52, and the liquid outlet area 56 is the liquid water outflow area. When the partition plate 53 moves, the sealing plate 533 deviates from the second outlet 52, the pull plate 531 closes the first outlet 51, and the liquid outlet area 56 is the liquid hydrogen outflow area. The air outlet area 57 is used to allow external airflow to flow in and mix with liquid hydrogen or volatilized gaseous hydrogen to reduce the hydrogen concentration and avoid potential safety hazards. According to the moving position of the partition plate 53, the converged gas ratio can be adjusted to adapt to different leakage amounts of liquid hydrogen.

[0046] like Figure 13 As shown, the hydrogenator 1 is equipped with a placement rack 11 and a protective cover 12 in conjunction with the hydrogenation gun 3 , and a cleaning assembly 6 is provided on the protective cover 12 .

[0047] like Figure 14 As shown, the cleaning assembly 6 includes an outer cover 61, which is rotatably set on the protective cover 12. The outer cover 61 is set as a hollow structure and is connected to a sponge block 62 on the lower side. The outer circumference of the upper side of the outer cover 61 is provided with side teeth 611, and the side teeth 611 are connected to the driving teeth 63, and the driving teeth 63 are connected to the driver 64.

[0048] In actual operation, the sponge block 62 is used to clean the liquid hydrogen remaining at the muzzle of the hydrogenation gun 3. When the driver 64 is started, the driving teeth 63 drive the side teeth 611 to rotate, so that the outer cover 61 drives the sponge block 62 to rotate, so that the sponge block 62 can fully contact the muzzle of the hydrogenation gun 3.

[0049] In one embodiment, Figure 15 As shown, a plurality of gas channels 621 are provided inside the sponge block 62 , one end of the gas channel 621 is opened to connect to the outer cover 61 , and a plurality of guide plates 612 are provided on the circumference of the inner wall of the outer cover 61 , and the guide plates 612 are arranged obliquely.

[0050] It should be noted that the liquid hydrogen absorbed by the sponge block 62 will evaporate inside, and the gas channel 621 is used to draw out the gaseous hydrogen. When the outer cover 61 drives the guide plate 612 to rotate, the lower airflow will flow upward along the surface of the guide plate 612, so that the gaseous hydrogen in the gas channel 621 is extracted, thereby preventing the hydrogen concentration inside the outer cover 61 from continuously increasing.

[0051] Optionally, a camera and an electrostatic discharger are provided on one side of the hydrogen filling machine 1. The camera is used to photograph the vehicle, and the electrostatic discharger is used to eliminate static electricity on the human body and the vehicle to be filled.

[0052] The hydrogenator 1 is provided with a breakaway valve 7 and a display 8. The breakaway valve 7 is used to prevent accidental breakage of the pipeline and improve the safety of the hydrogenator 1 during use. The display 8 is used to display relevant information during hydrogen filling, including filling amount, filling flow, price, filling temperature, etc.

[0053] The specific implementation methods are as follows:

[0054] Step 1: Identify the hydrogen vehicle to be refueled. The camera recognizes the vehicle license plate and provides feedback to obtain vehicle information and tank information.

[0055] Step 2: The staff checks the hydrogen car to be refueled. The driver drives the hydrogen car to the refueling parking space of hydrogen refueling machine 1. The staff checks the hydrogen car's storage tank and connecting pipes to ensure that the temperature is normal and there are no leaks.

[0056] Step 3: Connect the hydrogen vehicle to be refueled and refuel. The staff adjusts the refueling information according to the tank information, then uses an electrostatic discharger to eliminate its own static electricity. Then, the static connection clamp on the electrostatic discharger is connected to the tank area of the vehicle to be refueled to eliminate static electricity in the area and avoid danger caused by static electricity during the refueling process. Finally, the staff connects the hydrogen refueling gun 3 to the valve of the hydrogen tank and starts the hydrogen refueling machine 1 to refuel the tank.

[0057] Step 4: During the filling process, the sensing mechanism 4 detects leakage. When liquid drips from the surface of the upper liquid hydrogen delivery pipeline 2, the mass of the dripping liquid is recorded. After a set number of unit times, the total mass is checked to see if it decreases. If it decreases, it is determined that the dripping liquid is liquid hydrogen. If there is no obvious change, the dripping liquid is liquid water.

[0058] Step 5: Automatically update the refueling information, confirm the information and pay the amount. After the refueling is completed, the staff removes the hydrogen refueling gun 3 and the electrostatic connection clamp, and the display 8 shows the refueling information. The staff manually updates the information based on the actual refueling situation, and then the driver confirms the information and pays to complete the hydrogen refueling.

[0059] Specifically, in step 4, liquid hydrogen is extremely cold (approximately -253°C). When it leaks into a room-temperature environment, it quickly absorbs heat from the surrounding environment and vaporizes. Therefore, if the total mass of liquid dripping onto the surface of the receiving assembly 42 over a period of time is less than the accumulated value, the dripping liquid is determined to be liquid hydrogen. At this point, the corresponding first receiving plate 422 moves downward to the hydrogen collection layer 45, and the second outlet 52 opens, allowing liquid hydrogen or partially vaporized gaseous hydrogen to be drained from the hydrogen collection layer 45 to the drain tank 5. The main valve is closed, and the leak location is located for inspection.

[0060] Furthermore, the movement position of the partition plate 53 in the drain tank 5 is adjusted according to the dripping state of the liquid hydrogen. The interval between the two pressure signals is set to T, and a comparison value t is introduced. When T>t, the leakage state of the liquid hydrogen is within a controllable range. At this time, there is no need to close the main valve during the refueling process. The proportion of the converging gas in the drain tank 5 is adjusted according to the T value. The interval time is inversely proportional to the volume of the converging gas. In other words, the shorter the interval between the two pressure signals, the faster the liquid hydrogen leakage rate and the higher the concentration. More gas needs to be introduced to reduce the concentration and discharge. When T≤t, the leakage rate of the liquid hydrogen is abnormal. At this time, the main valve needs to be closed immediately, personnel need to be evacuated, the internal hydrogen station gas needs to be forced to ventilate and replace, and the staff need to be notified to carry out maintenance.

[0061] If the total mass of liquid dripping onto the surface of the receiving assembly 42 within a period of time is almost the same as the accumulated value, the dripping liquid is determined to be liquid water. At this time, the corresponding first receiving plate 422 moves down to the water collection layer 44, and the first outlet 51 is opened, and the liquid water is drained from the water collection layer 44 to the drainage box 5.
