Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy storage, and particularly relates to a hydrogen production and hydrogen filling integrated device. Background Art

[0002] With the development of hydrogen energy technology, a "hydrogen filling station" - a hydrogen production and hydrogen filling integrated device designed specifically for hydrogen energy bicycles such as shared hydrogen energy bicycles and household hydrogen energy bicycles has emerged as the times require.

[0003] However, the existing hydrogen production and hydrogen filling integrated devices usually only support solar energy or commercial power. For the hydrogen production and hydrogen filling integrated device that only supports solar power supply, due to the dependence of solar power generation on sunlight, its energy output has obvious intermittency and seasonal differences. The power generation is high on sunny days, while on cloudy, rainy or night days, it will significantly affect the efficiency of solar power generation, and sometimes it is difficult to ensure the continuity of power supply. For the hydrogen production and hydrogen filling integrated device that only supports commercial power, once there is a problem with the commercial power supply, such as a fault power outage, the device cannot operate. This high dependence on the commercial power grid reduces the reliability and adaptability of the device, making it unable to cope when facing unstable power grids or applications in remote areas. Therefore, developing a hydrogen production and hydrogen filling integrated device with a dual-input design of both solar power supply and commercial power to solve the user experience of using the device and obtain a higher operation cost performance is a major trend in this field.

[0004] In addition, the existing hydrogen production and hydrogen filling integrated devices often have problems of high production costs and operation and maintenance costs. Among them, the number of gas pipeline components in the existing devices is large, the pipeline layout is complex and the length is long, resulting in a high gas pipeline layout cost for the hydrogen production and hydrogen filling integrated device. And the complex gas pipeline layout makes the number of connection points, that is, the leakage points, large, resulting in difficult maintenance and high maintenance costs. At the same time, the design of the existing pipelines occupies a large space, which also leads to disadvantages such as large volume, low compactness, low integration and high cost of the whole machine.

[0033] As Figures 1-7 shown, the present utility model provides an integrated hydrogen production and hydrogen filling device, which includes a chassis 100, and a water supply module, a hydrogen production module, a hydrogen filling module, a hydrogen storage module, a control module and a power supply module arranged in the chassis 100.

[0034] Specifically, as Figure 1 andFigure 2 As shown, the water supply module includes a water storage tank 210, a water pump 220, and a purification column 230 that are connected in series through a water path. The water storage tank 200 is installed at the upper end of the chassis 100 through a first fixing member 110, so that the water injection port with a cover 211 provided at the top thereof can expose the upper end surface of the chassis 100 to facilitate the user to inject water into the water storage tank 210. An outlet 212, a first water return port 213, and a second water return port 214 are provided on the side end surface of the water storage tank 210. The outlet 212 is provided at the bottom of the side end surface of the water storage tank 210 to ensure the maximum drainage volume. The outlet 212 is connected to the water inlet end of the water pump 220 through a pipeline, the water outlet end of the water pump 220 supplies water to the water inlet end of the pure water column 230 through a pipeline, and the water outlet end of the pure water column 230 is connected to the water inlet of the hydrogen production module through a pipeline. The setting of the pure water column 230 can improve the water quality of the water supplied to the hydrogen production module and avoid shortening the service life of the hydrogen production device 310 due to water quality problems.

[0035] In this embodiment, setting the water pump 220 in the chassis 100 can further ensure the water supply pressure and the stability of the water supply. Therefore, the installation position of the water pump 220 can be arranged at any vacant position according to the overall layout requirements. However, for the purpose of reducing pipelines, it can be preferentially set below the water storage tank 210; and the purification column 230 is arranged at the middle position of the bottom of the chassis 100.

[0036] The hydrogen production module includes a hydrogen production device 310, a gas-water separation device 320, and a drying device 330. The hydrogen production device 310 can be a PEM electrolyzer, and its water inlet is connected to the water outlet end of the pure water column 230 through a pipeline; its hydrogen outlet is connected to the gas inlet of the upper end of the gas-water separation device 320. The gas-water separation device 320 is used for removing water and purifying the hydrogen produced by electrolyzing water by the hydrogen production device 310. Since the water removal capacity of the gas-water separation device 320 is limited, two drying devices 330 can be connected to the gas outlet of the upper end of the gas-water separation device 320 to further remove water to improve the purity of hydrogen. The oxygen outlet of the hydrogen production device 310 is connected to the first water return port 213 of the water storage tank 210 through a pipeline.

[0037] Furthermore, the oxygen and the remaining water produced by electrolyzing water by the hydrogen production device 310 are discharged through its oxygen outlet and enter the water storage tank 200 through the first water return port 213. At the same time, please refer to Figure 3, an oxygen intake port 2111 is provided on the cover 211, and the oxygen intake port 2111 can be provided at the center of the cover 211. To avoid excessive oxygen resulting in excessive pressure in the water storage tank 210, a plurality of pressure relief holes 2112 are also provided on the cover 211. The pressure relief holes 2112 can be arranged in an array centered on the oxygen intake port 2111, such as the circular array shown in the figure, or a rectangular array not shown in the figure. Compared with the prior art solution of separately providing an oxygen intake port at the top of the chassis, this design can simplify the overall pipeline layout of the all-in-one machine, and at the same time facilitate the reuse of the remaining water of the hydrogen production device 310, achieving efficient utilization of water resources.

[0038] Furthermore, since the water separated in the gas-water separation device 320 will sink to the bottom of the gas-water separation device 320 due to gravity and the water quality can be reused, a liquid outlet connected to the second water return port 214 of the water storage tank 210 can be provided at the bottom of the gas-water separation device 320 to further achieve efficient utilization of water resources.

[0039] Considering the pipeline connection relationship between the devices in the hydrogen production module and the devices in the water supply module, in order to minimize the length of each pipeline as much as possible and reduce the risk of air leakage and liquid leakage, in this embodiment, the gas-water separation device 320 is located on the side of the hydrogen production device 310 where the hydrogen outlet and oxygen outlet are provided. The hydrogen production device 310 can be arranged below the water storage tank 210 through the second fixing member 120 (see Figure 7 ) and is mounted on the bottom of the chassis 100. On the one hand, it can be closer to the upper intake port of the gas-water separation device 320, and on the other hand, it is convenient for the heat dissipation fan 314 (see Figure 7 ) to be provided on the side of the hydrogen production device 310 to dissipate heat from its bottom at the same time; the drying device 330 is horizontally fixed on one side of the gas-water separation device 320 through the third fixing member 130 and is mounted on the bottom of the chassis 100. On the one hand, it can be closer to the upper outlet of the gas-water separation device 320, and on the other hand, it can provide an installation space for the purification column 230 below.

[0040] As Figure 2 , Figure 4 and Figure 5As shown, the hydrogen charging module is connected to the hydrogen outlet of the drying device 330. The hydrogen charging module includes: a hydrogen charging pipeline communicating with the drying device 330, and a valve assembly 420 and a hydrogen charging connector 410 provided on the hydrogen charging pipeline. The hydrogen charging connector 410 mainly realizes a sealed connection with the hydrogen storage bottle 520 in the hydrogen storage module. The valve assembly 420 includes a multi-way connector 421, a first gas path control valve 422, a second gas path control valve 423, a first pressure sensor 424 and a second pressure sensor 425; the multi-way connector 421 is set as a cuboid, which is a five-way connector in this embodiment, and is provided with a hydrogen input port 4211, a first hydrogen output port 4212, a second hydrogen output port 4213, a first sensor connection port 4214 and a second sensor connection port 4215 that communicate with each other. The hydrogen input port 4211 can be provided at one end in the length direction of the multi-way connector 421 and is threadedly connected to the pipeline connecting to the hydrogen outlet of the drying device 330; the first hydrogen output port 4212 can be provided on the upper end surface of the multi-way connector 421 and is threadedly connected to one end of the first gas path control valve 422, and the other end of the first gas path control valve 422 is connected to the hydrogen storage bottle 520 of the downstream device through a pipeline; the second hydrogen output port 4213 can be provided at the other end in the length direction of the multi-way connector 421 and is threadedly connected to one end of the second gas path control valve 423, and the other end of the second gas path control valve 423 is connected to the hydrogen absorption port on the chassis 100 through a pipeline; the first sensor connection port 4214 and the second sensor connection port 4215 can be provided on the lower end surface of the multi-way connector 421 and are respectively threadedly connected to the first pressure sensor 424 and the second pressure sensor 425, so that the first pressure sensor 424 and the second pressure sensor 425 are arranged between the paths of the hydrogen input port 4211 and the first hydrogen output port 4212 and the second hydrogen output port 4213, so as to realize the monitoring of the hydrogen pressure in the hydrogen charging pipeline and the control of the on-off of the gas path according to the pressure.

[0041] Among them, the first pressure sensor 424 can be a pressure transmitter, which is used to monitor the pressure in the multi-way connector 421 path and output a pressure analog quantity to the main control motherboard 610 of the control module; the second pressure sensor 425 can be a pressure switch, which mainly plays an overpressure protection role. When the pressure in the multi-way connector 421 path is detected to reach the threshold value, a switch quantity is output to the main control motherboard 610, and the main control motherboard 610 detects a large pressure abnormality and reports it, opens the valve to relieve pressure, shuts down the hydrogen production device and other operations.

[0042] The hydrogen storage module includes a gas cylinder compartment 510 and hydrogen storage cylinders 520. The gas cylinder compartment 510 is horizontally arranged in the chassis 100 along the central axis of the hydrogen filling connector 410 and is suitable for horizontally placing the hydrogen storage cylinders. The specific structures, positional relationships, and connection relationships of the hydrogen filling connector 410, the gas cylinder compartment 510, and the hydrogen storage cylinders have been described in detail in the applicant's prior application CN219588709U and will not be elaborated here.

[0043] Further, please refer back to Figure 1 , a gas cylinder compartment cover 180 is provided on the chassis 100. The installation position of the gas cylinder compartment cover 180 corresponds to the installation position of the gas cylinder compartment 510 and is on the same horizontal line as the hydrogen filling connector 410. A reader-writer is built into the gas cylinder compartment cover 180 and is connected to the main control motherboard 610 of the control module for non-contact communication connection with an electronic chip provided at the bottom of the hydrogen storage cylinder. When the user places the hydrogen storage cylinder into the gas cylinder compartment 510 with the bottle head facing in and the bottle bottom facing out, and then covers the gas cylinder compartment cover 180, the reader-writer is close to the electronic chip, and the information in the electronic chip can be read, and the real-time hydrogen content of the hydrogen storage cylinder can be updated and recorded according to the real-time hydrogen filling situation.

[0044] Further, since the hydrogen storage cylinder continuously releases heat during the hydrogen filling process, in order to ensure the hydrogen filling efficiency of the gas cylinder compartment 510, it is necessary to dissipate heat from the gas cylinder compartment 510 and the hydrogen storage cylinders. In this embodiment, a thermoelectric cooler, a heat sink, and a fan are sequentially arranged below the gas cylinder compartment 510. The thermoelectric cooler is used to cool the bottom of the gas cylinder compartment 510, the heat sink is used to conduct heat, and the fan below is used to discharge the heat, thereby realizing cooling and heat dissipation.

[0045] As Figure 6 shown, the control module includes a main control motherboard 610 and a solar control motherboard 620. The main control motherboard 610 and the solar control motherboard 620 can be vertically installed at the bottom of the chassis 100 through a punched fixing plate 650 and are located below the hydrogen storage module. The main control motherboard 610 is electrically connected to each electrical device in the water supply module, the hydrogen production module, the hydrogen filling module, and the hydrogen storage module for signal control of the operation of each device; the main control motherboard 610 is also electrically connected to the power supply module for signal control of whether the power supply module supplies power or not; the solar control motherboard 620 is externally connected to a solar panel through a solar panel access port 140 provided on the outer side of the chassis 100 for controlling and managing the direct current output by the solar panel, and the output electric energy is transmitted to the electrical device via the power supply module.

[0046] Please refer to Figure 3 and Figure 7, the power supply module includes a first power supply 630 and a second power supply 640, and the first power supply 630 and the second power supply 640 are fixed on the backplane 170 of the chassis 100 from top to bottom. The first power supply 630 and the second power supply 640 are respectively electrically connected to the main control motherboard 610, the solar control motherboard 620, and the mains access port 160 provided on the outer side surface of the chassis 100; the first power supply 630 can be a 24V power supply for supplying power to each electrical device except the hydrogen production device 310; the second power supply 640 is a hydrogen production power supply for separately supplying power to the hydrogen production device 310. When the hydrogen production and filling integrated device is externally connected to the mains, the mains access port 160 receives 220V alternating current, which is converted into 24V direct current through a switching power supply and then transmitted to the first power supply 630 and the second power supply 640 for power supply.

[0047] Further, in order to realize the wiring management of complex wire lines and reduce the risks of circuit faults such as short circuits and poor contacts, a wire slot 102 can be provided in the chassis 100. In this embodiment, the wire slot 102 can be provided on the back of the display screen 101. The display screen 101 is provided on the front of the chassis 100 for externally displaying device operation information. Specifically, the display screen 101 can be fixedly installed between the water storage tank 210 and the first power supply 630 through the backplane 170, so that the wire slot 102 can proximally restrain the wires coming out of the control module and the power supply module.

[0048] Further, in this embodiment, there are two wire slots 102, and the two wire slots 102 are arranged in parallel on the upper and lower sides of the back of the display screen 101. Designing two wire slots 102 can separately manage the wires coming out of the control module and the power supply module, or separately manage the wires coming out of the control module and power supply module devices located in the upper half of the chassis 100 and the wires coming out of the control module and power supply module devices located in the lower half of the chassis 100, so as to more efficiently identify faults and complete maintenance faster. At the same time, it facilitates the carrying out of daily inspection and maintenance work, reduces the circuit repair time and cost; in addition, it can also make the internal wires be placed orderly and improve the aesthetics. It should be noted that in some other embodiments, the two wire slots 102 can also be arranged in parallel on the left and right sides of the back of the display screen 101. The wire slot 102 can also be provided with more than two, but two are sufficient to meet the wiring requirements and are more economical and practical.
