Description

Technical Field

[0001] This invention relates to the field of hydrogen production technology, specifically to an integrated device for biomass hydrogen production and energy storage. Background Technology

[0002] Against the backdrop of the current global energy structure transition towards clean and low-carbon energy, hydrogen energy, as a key secondary energy source for achieving the "dual carbon" goal, has attracted much attention for its green production technology. Biomass hydrogen production, especially the catalytic reforming hydrogen production route using bio-methanol as a raw material, has become an important direction with promising industrialization prospects due to its renewable raw materials and significant carbon cycle advantages. This technology mainly obtains high-purity hydrogen through the reforming of methanol and water vapor under the action of a catalyst and subsequent purification processes. However, existing biomass hydrogen production systems generally adopt a separate design for hydrogen production, purification, and storage units, resulting in low system integration, large footprint, and high energy consumption. More prominently, the system lacks an effective collaborative management mechanism, making it impossible to integrate and optimize the dynamic factors such as the large amount of reaction heat, gas pressure fluctuations, and impurity generation that inevitably occur during the reforming reaction. Each unit often operates independently, resulting in poor matching of energy and material flow, and the overall energy efficiency and economy need to be improved.

[0003] Existing technologies suffer from several key bottlenecks affecting the long-term stability and high efficiency of the system. The thermal management efficiency of the reaction process is insufficient, and if excess heat cannot be removed in time, it can easily lead to catalyst deactivation and safety hazards. Current cooling solutions mostly rely on external high-energy-consuming independent systems. The adsorption materials used for hydrogen purification are prone to failure due to impurity saturation during long-term operation. Traditional maintenance methods require shutdown for treatment, making it difficult to achieve online self-cleaning and regeneration, which seriously restricts the continuous operation capability of the system. In addition, the actuators that drive auxiliary functions such as cooling and purification switching usually rely on external power for independent driving, failing to recover and convert the considerable potential energy such as waste heat and pressure difference inside the system into power to drive these functions. This not only increases the complexity and manufacturing cost of the system, but also leads to secondary energy waste, which deviates from the intensive and efficient requirements of green hydrogen production technology. Summary of the Invention

[0018] This invention provides an integrated device for biomass hydrogen production and energy storage. It has the following beneficial effects:

[0019] 1. This invention drives the piston disc to reciprocate through the gas pressure changes generated by the hydrogen production reaction itself, which in turn links the rotating rod, rotating disc and other components to provide power for the entire process mechanism, including subsequent cooling, filtration and cleaning, and impurity removal. It does not require an external power source and achieves pure mechanical self-drive, which greatly reduces operating costs.

[0021] 3. This invention uses a cam and spring linkage structure to vibrate the activated carbon plate, shaking off solid impurities adhering to its surface. A pentagonal telescopic column and cleaning plate linkage structure drive the cleaning plate to move up and down, scraping away deep impurities on the outer wall of the activated carbon plate. This avoids losses due to clogging, such as decreased filtration efficiency and downtime maintenance, achieving online self-cleaning of the activated carbon plate without manual intervention, ensuring long-term stable hydrogen filtration efficiency; extending the replacement cycle of the activated carbon plate, and reducing equipment maintenance frequency and consumable costs.

The coordinated operation of each link is achieved through a mechanical transmission chain, overcoming the shortcomings of existing hydrogen production systems, such as the dispersed arrangement of functional modules, complex pipeline connections, and large footprint. In particular, it is not suitable for the needs of miniaturized and mobile hydrogen production scenarios. The device has a compact structure and high integration, which can be adapted to the needs of laboratories, small factories, or mobile hydrogen production, improving space utilization and reducing installation and commissioning difficulty.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1As shown, this embodiment of the invention provides an integrated device for biomass hydrogen production and energy storage, including a base 1. The entire device is mounted on the base 1 and includes a hydrogen production reaction module, a hydrogen storage module, and a pressure-driven auxiliary system. The hydrogen production reaction module mainly includes a manufacturing tank 11, which contains a reaction tank 14 and a purification device 15 for completing the methanol steam reforming reaction and removing carbon monoxide impurities. The hydrogen storage module includes a storage tank 2, which is connected to the manufacturing tank 11 via a connecting pipe 41 for temporarily storing purified hydrogen. The top of the storage tank 2 is equipped with a gas injection pipe 21 for injecting bio-methanol feedstock. The base 1 is also equipped with a control component 12 and a control system. Panel 13 is used to adjust the material conveying ratio and monitor the operating status. The purification device 15 adopts catalytic oxidation technology and is filled with a palladium-based precious metal catalyst. When the mixed gas flows through the purification device, carbon monoxide reacts with trace amounts of oxygen in the gas to produce carbon dioxide, thereby achieving efficient removal of carbon monoxide and obtaining high-purity hydrogen. The storage tank 2 is equipped with a sealed partition, which divides it into an independent methanol storage chamber and a hydrogen storage chamber. The methanol storage chamber is connected to the gas injection pipe and is used to store bio-methanol raw materials. The hydrogen storage chamber is connected to the connecting pipe and is used to temporarily store purified hydrogen. The partition adopts a pressure-resistant and sealed structure to prevent the two media from mixing.

[0037] During the equipment startup phase, the operator injects bio-methanol into the storage tank 2 through the gas injection pipe 21, and controls the methanol and water to enter the reaction tank 14 inside the manufacturing tank 11 according to a set ratio through the control unit 12. In the reaction tank 14, methanol and water vapor undergo a reforming reaction under the action of a catalyst to generate a hydrogen-containing mixed gas. This gas then enters the purification device 15 to remove harmful impurities such as carbon monoxide, obtaining high-purity hydrogen. As the reaction proceeds, the internal pressure of the manufacturing tank 11 gradually increases. When the pressure reaches a certain threshold, it pushes the piston disc 314 to extend outward in a linear motion. The piston disc 314 is sealed and slidably mounted on the manufacturing tank. Inside the cavity opened in the side wall of the tank 11, its outer end is hinged to one end of the rotating rod 31 via the connecting frame 313. The middle part of the rotating rod 31 is eccentrically hinged to the rotating disk 3, and the rotating disk 3 is fixedly sleeved on the rotating shaft 33, thus forming a typical crank-slider mechanism, which converts the linear reciprocating motion of the piston disk 314 into the rotational motion of the rotating shaft 33. The piston disk 314 is sealed in the cylinder opened in the side wall of the manufacturing tank 11 by a high-precision sealing ring or stuffing box (not shown in the figure, but it is a well-known technology in the art), ensuring that it can flexibly reciprocate in response to changes in the pressure inside the tank, while preventing the leakage of reaction gas.

[0038] like Figure 2As shown, a first bevel gear 32 is fixedly connected to one end of the rotating shaft 33. The first bevel gear 32 meshes with a second bevel gear 35. The second bevel gear 35 is fixedly mounted on the rotating rod 36, and the rotating rod 36 is set perpendicular to the rotating shaft 33 and supported by a bearing on the support column 34 on the base 1. Therefore, when the rotating shaft 33 rotates, the power is transmitted to the rotating rod 36 through the gear pair composed of the first bevel gear 32 and the second bevel gear 35, so that it rotates synchronously. A first drive sprocket 39 and a third bevel gear 37 are fixedly mounted on the rotating rod 36, which are used to drive the cooling unit and the filter cleaning unit, respectively.

[0039] like Figure 4 and Figure 5 As shown, the cooling unit includes a fan blade 310, a connecting column 315, a first driven sprocket 316, and a first chain 38. A first driving sprocket 39 is connected to the first driven sprocket 316 via the first chain 38. The first driven sprocket 316 is fixed to the connecting column 315. One end of the connecting column 315 is supported on the side wall of the manufacturing tank 11 by a bearing, and the other end is fixedly mounted with the fan blade 310. When the rotating rod 36 rotates synchronously with the second bevel gear 35, it drives the first driving sprocket 39 to rotate, which in turn drives the first driven sprocket 316 and the fan blade 310 to rotate via the first chain 38, thus providing forced airflow to the side wall of the manufacturing tank 11. The cooling effect is achieved because the rotational speed of the fan blade 310 is positively correlated with the internal pressure of the manufacturing tank 11. That is, the higher the hydrogen production reaction rate and the greater the pressure, the greater the displacement amplitude of the piston disc 314 and the higher the rotational speed of the fan blade 310. This achieves a dynamic match between the cooling intensity and the reaction heat load, forming a negative feedback thermal management mechanism. The fan blade 310 is evenly arranged circumferentially along the side wall of the manufacturing tank, and the rotation direction of the fan blade 310 is adapted to the heat flow diffusion direction of the outer wall of the manufacturing tank 11 to enhance the cooling effect of the air cooling on the manufacturing tank 11. At the same time, the fan blade 310 is made of high-temperature resistant alloy material, which can adapt to the high-temperature working conditions of the outer wall of the manufacturing tank 11 and avoid material failure.

[0040] like Figure 7 As shown, the filtration and cleaning unit is located inside the processing box 4, which is connected in series with the connecting pipe 41 and is situated between the manufacturing tank 11 and the storage tank 2. The processing box 4 contains an activated carbon plate 48 for adsorbing trace impurities remaining in the gas. To prevent the activated carbon plate 48 from becoming clogged or coking due to long-term use, this invention includes a shaking component and a cleaning component, both of which are linked to the rotating rod 36 via a power transmission path. The shaking component includes a third bevel gear 37, a fourth bevel gear 42, a universal joint 43, a rotating column 44, a second chain drive mechanism, and a cam vibration mechanism. Figure 3 and Figure 6As shown, the third bevel gear 37 is fixedly mounted on the rotating rod 36 and meshes with the fourth bevel gear 42; the fourth bevel gear 42 is fixed on the fixed shaft 46, which is connected to the rotating column 44 via a universal joint 43. The universal joint 43 can compensate for axial misalignment caused by assembly errors or thermal deformation, ensuring smooth transmission. A second drive sprocket 417 is fixedly mounted on the rotating column 44, and the second drive sprocket 417 is connected to the second driven sprocket 410 via a second chain 416. The second driven sprocket 410 is fixed to the rotating column 44 at the other end. In addition, a cam 418 is fixedly installed on the rotating column 44. The outer periphery of the cam 418 contacts the push plate 411. The push plate 411 is slidably disposed in the guide groove provided in the inner wall of the treatment box 4 and is fixedly connected to the activated carbon plate 48. A spring 412 is provided between the push plate 411 and the inner wall of the treatment box 4 to reset the push plate 411 when the cam 418 disengages. When the rotating column 44 rotates, the cam 418 periodically pushes the push plate 411 to perform reciprocating linear motion, causing the activated carbon plate 48 to vibrate, effectively preventing the filter holes from clogging.

[0041] The cleaning assembly includes a fifth bevel gear 414, a sixth bevel gear 415, a rotating disk 5, an arc-shaped guide plate 510, a sliding rod 57, and a cleaning plate 59. The fifth bevel gear 414 is fixedly mounted on the rotating column 44 and meshes with the sixth bevel gear 415; the shaft of the sixth bevel gear 415 is fixedly connected to the rotating disk 5, such as... Figure 11 As shown, a limiting post 54 is provided on the end face of the rotating disk 5. The limiting post 54 slides along the arc-shaped guide plate 510 fixedly installed inside the processing box 4. One end of the sliding rod 57 is connected to the rotating disk 5 through the telescopic post 55 and the limiting sleeve 56, and the other end is hinged to the fixed sleeve 58. A cleaning plate 59 is fixedly installed on the fixed sleeve 58. When the rotating disk 5 rotates with the sixth bevel gear 415, the limiting post 54 slides along the arc-shaped guide plate 510, forcing the sliding rod 57 to make linear reciprocating motion, thereby driving the cleaning plate 59 to reciprocate along the surface of the activated carbon plate 48. The cleaning plate 59 scrapes and removes accumulated dust or coke. Furthermore, the treatment box 4 is equipped with a baffle 47 to guide the airflow evenly through the activated carbon layer and prevent airflow short-circuiting. The protective cover 49 covers the transmission components to prevent activated carbon dust from entering the gear and chain system and to ensure transmission reliability. The scraping surface of the cleaning plate 59 is in close contact with the surface of the activated carbon plate 48, and the linear reciprocating stroke of the cleaning plate 59 covers the entire effective filtration area of ​​the activated carbon plate 48, ensuring that there are no dead corners in scraping the impurities on the surface of the activated carbon plate 48 and ensuring stable filtration efficiency.

[0042] In particular, such as Figure 10 and Figure 11As shown, the activated carbon plate 48 is slidably connected to the pentagonal fixed sleeve 53 via the pentagonal telescopic column 51. The pentagonal fixed sleeve 53 is fixedly connected to the rotating disk 5 via the connecting rod 52. The cross-section of the pentagonal telescopic column 51 is a regular pentagon, and the inner hole shape of the pentagonal fixed sleeve 53 matches it, so that the activated carbon plate 48 can freely extend and retract in the axial direction, but is restricted from rotating in the circumferential direction. This structure ensures that the activated carbon plate 48 maintains azimuth stability during vibration, and at the same time has the ability to adapt to displacement, avoiding structural damage or jamming caused by rigid constraints. In addition, a baffle 47 is also provided in the treatment box 4. The baffle 47 is located upstream of the activated carbon plate 48 and is used to guide the airflow to be evenly distributed, avoiding excessive local flow velocity that could cause filter material wear. The transmission components inside the treatment box 4 are provided with a protective cover 49. The protective cover 49 covers the second chain transmission mechanism, cam 418, universal joint 43 and bevel gear set to prevent dust from entering the transmission system and ensure long-term operational reliability.

[0043] To further explain, the meshing surfaces of the gear pairs and the contact surfaces between the chain and sprocket in the chain drive are all coated with high-temperature resistant grease. This grease can maintain stable lubrication performance within the operating temperature range of the equipment, reduce the wear rate of transmission components, and ensure the long-term reliability of power transmission.

[0044] Working Principle: Bio-methanol is injected into the right side of the storage tank 2 through the injection pipe 21. The methanol delivery is controlled by the bottom delivery pipe and control components, and is delivered to the manufacturing tank 11. Inside, the methanol is ignited by the ignition device at the rear right side of the base 1. The methanol-water mixture is injected into the system and heated by the ignition device (actually a heating device), quickly turning into high-temperature steam. The high-temperature methanol-water vapor flows through the reaction chamber filled with catalyst. Under the action of the catalyst, methanol and water molecules undergo a chemical reaction, decomposing into hydrogen (H2), carbon dioxide (CO2), and trace amounts of carbon monoxide. The produced gas is further treated by the internal purification device 15 (such as catalytic oxidation) to remove harmful carbon monoxide, finally obtaining a hydrogen-rich mixed gas, which is delivered through the connecting pipe 41. The equipment is equipped with an independent heating device (such as an electric heater or burner, which corresponds to the "ignition device" in the original text) to provide the heat required for the reforming reaction in the reaction tank 14. The pressure fluctuations in the hydrogen production process mainly originate from the accumulation of reaction-generated gases (H2, CO2, etc.). With the supply of methanol, gases are continuously generated in the reaction tank 14 during the hydrogen production reaction, causing the internal pressure of the manufacturing tank 11 to rise; when the reaction slows down or stops, the pressure drops.This periodic pressure change drives the piston plate 314 to reciprocate linearly, causing the rotating disk 3 to rotate, which in turn drives the internal rotating shaft 33 to rotate. Gravity allows the piston plate 314 to return to its original position. The greater the internal pressure, the higher the rotational speed of the rotating shaft 33. This rotation, via the first bevel gear 32, drives the second bevel gear 35 to rotate, causing the rotating rod 36 to rotate. The rotating rod 36 then drives the first drive sprocket 39 to rotate, which, along with the first chain 38, drives the first driven sprocket 316 to rotate. This causes the connecting column 315 inside the first driven sprocket 316 to rotate, which in turn drives the fan blade 313 to rotate, cooling the outer wall of the manufacturing tank 11 and the entire device. Rotating rod 36 rotates, driving the third bevel gear 37 at the middle end to rotate. The third bevel gear 37 meshes with the fourth bevel gear 42, causing the fixed shaft 46 to rotate. The connecting sleeve 45 limits the movement of the fixed shaft 46. The fixed shaft 46 drives the universal joint 43 to rotate, which in turn drives the rotating column 44 to rotate. The rotation of the rotating column 44 drives the internal second drive sprocket 417 to rotate. The second drive sprocket 417 and the second chain 416 drive the second driven sprocket 410 to rotate, causing the rotating columns 44 at both ends to rotate. This drives the cam 418 to rotate, which in turn drives the push disk 411 to compress. The push disk 411 and the fixed block 413 have springs 412 inside, causing the push disk 411 to vibrate. The activated carbon plate 48 is shaken to filter solid impurities in the generated hydrogen gas. The rotating column 44 at one end rotates, causing the fifth bevel gear 414 to rotate. Through the rotation of the fifth bevel gear 414 and the sixth bevel gear 415, the pentagonal fixing sleeve 53 rotates. A pentagonal telescopic column 51 slides inside the pentagonal fixing sleeve 53, driving the pentagonal telescopic column 51 to rotate. The pentagonal fixing sleeve 53 rotates together with the rotating disk 5. However, due to the pentagonal sliding fit between the pentagonal telescopic column 51 and the pentagonal fixing sleeve 53, the circumferential rotation of the activated carbon plate 48 is restricted, allowing only axial extension and retraction. The main reciprocating motion of the activated carbon plate 48 is driven by the cam 418 through the pusher disk 411. The movement of the component is independent of the vibration of the activated carbon plate 48. It is specifically responsible for scraping its surface and driving the cleaning component to move. It rotates through the rotating disk 5, which drives the limiting column 54 to rotate. The arc-shaped guide plate 510 drives the sliding rod 57 to move up and down. The limiting sleeve 56 and the telescopic column 55 limit the sliding rod 57. At the same time, the telescopic column 55 can extend and retract to adapt to the shaking of the activated carbon plate 48. The sliding rod 57 slides, which drives the fixed sleeve 58 and the cleaning plate 59 to move, cleaning the outer wall of the activated carbon plate 48, improving the filtration efficiency, and periodically cleaning the internal impurities. Hydrogen is transported to the left side of the storage tank 2 for storage through the connecting pipe 41.
