Description

Technical Field

[0001] This utility model relates to the field of hydrogen production reactor technology, specifically a self-heating reforming hydrogen production reactor. Background Technology

[0002] Hydrogen is difficult to store, and existing hydrogen storage technologies suffer from drawbacks such as low storage density, high cost, and high storage pressure. Using high-energy-density renewable liquid fuels, such as low-carbon alcohols, and implementing on-site reforming reactors to produce hydrogen can provide an immediate supply of hydrogen and effectively solve the hydrogen supply problem. Steam reforming hydrogen production technology, represented by methanol, is the most mature and widely used.

[0003] Patent CN115784153B discloses a self-heating alcohol reforming hydrogen production reactor. The heating element is activated to heat the preheated bed. The heat from the preheated bed is transferred to the combustion and reforming beds via the combustion and reforming heat transfer elements. The heating element is shut off when the temperatures of the preheated, combustion, and reforming beds reach a preset temperature. At this time, the preheated bed preheats the feed pipes, causing the raw material (alcohol solution) in the feed pipes to vaporize. The vaporized alcohol in the feed pipes is transported to the inner cavity of the reforming bed, where a steam reforming reaction occurs at a corresponding preset temperature to generate hydrogen-rich gas. At this point, part of the hydrogen-rich gas flows to the combustion bed and burns at the corresponding preset temperature to release a large amount of heat. The heat released by the hydrogen combustion in the combustion bed is transferred to the preheating bed and the reforming bed in sequence through the combustion heat conduction section and the reforming heat conduction section, so as to provide heat for the reforming reaction while facilitating the vaporization of alcohol solutions. The other part flows to the hydrogen outlet pipe for collection.

[0004] The above-mentioned technical solution preheats the alcohol solution by transferring the heat generated by combustion in the combustion chamber to the interior of the preheating layer, thereby reducing the consumption of combustion energy. However, in this process, the heat transfer efficiency is low due to the heat conduction effect alone, and the preheating effect of the alcohol solution inside the pipeline is uneven. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a self-heating reforming hydrogen production reactor to solve the problems mentioned in the background. This invention features a novel structure. By driving the outer frame to rotate through a drive component, the water inside the annular water tank flows, and the pull rope drives the vertical plate to move left and right along the transverse water tank, improving the fluidity of the water in the annular and transverse water tanks. This allows the heat transferred by the heat-conducting rod to be evenly distributed throughout the preheating layer, improving the preheating effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-heating reforming hydrogen production reactor, comprising a reactor body, a preheating assembly at the top of the reactor body, the preheating assembly including a preheating layer, serpentine tubes fixed at equal intervals inside the preheating layer, an inlet end fixed at the top of the serpentine tubes extending through the preheating layer, and a nozzle at the bottom of the serpentine tubes extending through the preheating layer, an annular water tank surrounding the preheating layer, and a transverse water tank located between two sets of serpentine tubes inside the preheating layer, the two ends of the transverse water tank communicating with the annular water tank, and an outer frame rotatably mounted on the outer side of the annular water tank of the preheating layer, a driving assembly fixed at the bottom of the outer frame, the driving assembly including a vertical plate that slides along the interior of the transverse water tank.

[0007] Furthermore, a fuel pipe is provided on the top of the preheating layer, and a burner is connected to the lower end of the fuel pipe. The outlet end of the burner is connected to the top of the preheating layer.

[0008] Furthermore, the drive assembly also includes a gear ring, the outer surface of the outer frame is fixed with a gear, and one side of the gear ring is meshed with a gear. The reactor body is fixed with a motor on the outer wall at the bottom of the gear, and the output end of the motor is fixedly connected to the gear.

[0009] Furthermore, push plates are fixed at equal intervals on the top inner wall of the outer frame, and the push plates are set on half of the top area of ​​the outer frame. A rotating frame is rotatably installed inside the annular water tank on the outside of the preheating layer, corresponding to the connection positions at both ends of the transverse water tank. Horizontal plates are fixed at equal intervals on the surface of the rotating frame, and the horizontal plates of the rotating frame alternately press and contact the push plates.

[0010] Furthermore, a winding seat is fixed to the bottom of the rotating frame, and the same pull rope is wound in the winding seats at both ends of the transverse water tank, and the vertical plate is fixed to the surface of the pull rope.

[0011] Furthermore, the preheating assembly also includes an exhaust pipe, with exhaust pipes provided on the top of the preheating layer and the side of the reaction chamber body.

[0012] Furthermore, heat-conducting rods are fixed at equal intervals inside the combustion layer inside the reactor body, and the heat-conducting rods are inserted into the annular water tank.

[0013] Furthermore, a combined discharge port is provided at the bottom of the reactor body.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes the principle that when the outer frame rotates, it drives the push plate to move. After the push plate comes into contact with the horizontal plate on one side of the rotating frame, it causes the rotating frame to rotate, thereby causing the winding seat to wind up the pull rope. The vertical plate moves along one side of the horizontal water tank under the traction of the pull rope, pushing the water flow to one side. Because the push plate is only set in half of the range, when the outer frame rotates to the other side, the push plate comes into contact with the rotating frame on the other side, and the winding seat on the other side winds up the pull rope in the opposite direction. Then, the vertical plate slides to the other side of the horizontal water tank, thereby realizing the reciprocating flow of water.

[0016] This invention uses a motor to drive a gear to rotate, which meshes with a gear ring and in turn drives the outer frame to rotate. The inner wall of the outer frame has protrusions that prevent it from colliding with the heat-conducting rod. The outer frame drives the water in the annular water tank to flow, so that the heat transferred by the heat-conducting rod can be evenly absorbed by the water.

[0017] Compared with the prior art, this utility model drives the outer frame to rotate through the drive component, causing the water inside the annular water tank to flow, and the pull rope drives the vertical plate to move left and right along the horizontal water tank, improving the fluidity of the water in the annular and horizontal water tanks. As a result, the heat transferred by the heat-conducting rod can be evenly distributed throughout the entire preheating layer, improving the preheating effect. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a self-heating reforming hydrogen production reactor, including a reactor body 1. A preheating component 2 is provided on the top of the reactor body 1. The preheating component 2 includes a preheating layer 23. A serpentine tube 28 is fixedly fixed at equal intervals inside the preheating layer 23. The top of the serpentine tube 28 extends through the preheating layer 23 and is fixed with an inlet end 25. The bottom of the serpentine tube 28 extends through the preheating layer 23 and is provided with a nozzle. An annular water tank is provided around the preheating layer 23. A transverse water tank 27 is provided inside the preheating layer 23 between two sets of serpentine tubes 28. Both ends of 7 are connected to the annular water tank, and an outer frame 24 is rotatably installed on the outside of the annular water tank of the preheating layer 23. The bottom of the outer frame 24 is fixed with a driving component 3. The driving component 3 includes a vertical plate 34. The vertical plate 34 slides along the inside of the transverse water tank 27. When the device is in use, the high temperature generated in the combustion chamber at the bottom of the reactor body 1 is transferred to the water inside the annular water tank through the heat-conducting rod 12. The driving component 3 drives the water to flow along the annular water tank and the transverse water tank 27, so that the water can evenly absorb the heat transferred by the heat-conducting rod 12 and transfer it to the serpentine tube 28 to preheat the fuel transported in the serpentine tube 28.

[0026] In this embodiment, a fuel pipe 21 is provided on the top of the preheating layer 23, and a burner 22 is connected to the lower end of the fuel pipe 21. The outlet end of the burner 22 is connected to the top of the preheating layer 23. The preheating assembly 2 also includes an exhaust pipe 26. Exhaust pipes 26 are provided on the top of the preheating layer 23 and on the side of the reaction chamber body. A combined exhaust port 11 is provided at the bottom of the reactor body 1. The principle of the burner 22 inside the reactor body 1, as well as the upper exhaust pipe 26 and the lower combined exhaust port 11, in this device is the same as the technical method in patent CN115784153B. Fuel and oxidant enter the burner 22 through the fuel inlet pipe 21 to generate high-temperature flue gas. The gas enters the preheating layer 23 to heat the serpentine tube 28 within it. The high-temperature exhaust gas is finally discharged from the exhaust pipe 26. When the alcohol solution flows into the preheating layer 23, it can be heated and vaporized into alcohol vapor, which enters the uniform distribution chamber through the nozzle. The heat from the preheating layer 23 can be transferred to the combustion bed through the combustion heat pipe. At a suitable temperature, a steam reforming reaction occurs, producing hydrogen-rich gas. The hydrogen-rich gas enters the exhaust chamber from the reforming bed. The hydrogen in the hydrogen-rich gas is divided into three parts and flows out from the combined exhaust port 11. A large amount of heat is released during combustion, which can be transferred to the preheating layer 23 through the heat-conducting rod 12 to heat the serpentine tube 28 and vaporize the alcohol solution.

[0027] In this embodiment, the drive assembly 3 further includes a gear ring 33. The gear ring 33 is fixed on the outer surface of the outer frame 24, and a gear 32 is meshed with one side of the gear ring 33. A motor 31 is fixed on the outer wall of the reactor body 1 at the bottom of the gear 32, and the output end of the motor 31 is fixedly connected to the gear 32. Heat-conducting rods 12 are fixed at equal intervals inside the combustion layer inside the reactor body 1, and the heat-conducting rods 12 are inserted into the annular water tank. The motor 31 drives the gear 32 to rotate and mesh with the gear ring 33, thereby driving the outer frame 24 to rotate. There are protrusions on the inner wall of the outer frame 24, which will not collide with the heat-conducting rods 12. The water in the annular water tank is driven by the outer frame 24, so that the heat transferred by the heat-conducting rods 12 can be evenly absorbed by the water.

[0028] In this embodiment, push plates 35 are fixed at equal intervals on the top inner wall of the outer frame 24, and the push plates 35 are located on half of the top area of ​​the outer frame 24. A rotating frame 36 is rotatably installed inside the annular water tank outside the preheating layer 23, corresponding to the connection points at both ends of the transverse water tank 27. Horizontal plates are fixed at equal intervals on the surface of the rotating frame 36, and the horizontal plates of the rotating frame 36 alternately press against the push plates 35. A winding seat 37 is fixed to the bottom of the rotating frame 36. The same pull rope 38 is wound into the winding seats 37 at both ends of the transverse water tank 27, and a vertical plate 34 is fixed to the surface of the pull rope 38. The outer frame 24... When rotating, the push plate 35 moves. After the push plate 35 presses against the horizontal plate on the rotating frame 36 on one side, it drives the rotating frame 36 to rotate, thereby winding the pull rope 38 by the winding seat 37. The vertical plate 34 moves along one side of the horizontal water tank 27 under the traction of the pull rope 38, pushing the water flow to one side. Because the push plate 35 is only set in half of the range, when the outer frame 24 rotates to the other side, the push plate 35 presses against the rotating frame 36 on the other side, and the pull rope 38 is wound in the opposite direction from the winding seat 37 on the other side. Then the vertical plate 34 slides to the other side of the horizontal water tank 27, thereby realizing the reciprocating flow of water.

[0029] When the device is in use, the high temperature generated in the combustion chamber at the bottom of the reactor body 1 is transferred to the water inside the annular water tank through the heat-conducting rod 12. The motor 31 drives the gear 32 to rotate, which meshes with the gear ring 33, thereby driving the outer frame 24 to rotate. The inner wall of the outer frame 24 has protrusions that prevent it from colliding with the heat-conducting rod 12. The outer frame 24 drives the water in the annular water tank to flow, so that the heat transferred by the heat-conducting rod 12 can be evenly absorbed by the water. When the outer frame 24 rotates, it drives the push plate 35 to move. After the push plate 35 presses against the horizontal plate on the rotating frame 36 on one side, it drives the rotating frame 36 to rotate, thereby winding up the seat. The 37 pairs of pull ropes 38 are wound up, and the vertical plate 34 moves along one side of the transverse water tank 27 under the traction of the pull ropes 38, pushing the water flow to one side. Because the push plate 35 is only set in half of the range, when the outer frame 24 rotates to the other side, the push plate 35 presses against the rotating frame 36 on the other side, and the pull ropes 38 are wound up in the opposite direction from the winding seat 37 on the other side. Then the vertical plate 34 slides towards the other side of the transverse water tank 27, thereby realizing the reciprocating flow of water, so that the water can evenly absorb the heat transferred by the heat-conducting rod 12 and transfer it to the serpentine tube 28 to preheat the fuel transported in the serpentine tube 28.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
