Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy power generation, and specifically to a methanol reforming hydrogen production power supply system. Background Art

[0002] The methanol reforming hydrogen production power supply system consists of multiple components, including a reforming reactor, a separator, a heat exchanger, a power supply component, etc. However, the compatibility and synergy between these components in the existing system are poor.

[0003] In addition, in the methanol reforming hydrogen production reaction, the performance of the catalytic particles is often not satisfactory. For example, during the reforming reaction process, some catalytic particles not only promote the main reaction of converting methanol into hydrogen, but also trigger a series of side reactions. The generation of these by-products not only reduces the purity of hydrogen, but also damages the subsequent equipment. For example, carbon monoxide can poison the platinum electrode of the fuel cell, reducing the performance and lifespan of the fuel cell.

[0004] In addition, the stability of the catalytic particles is difficult to guarantee during long-term operation. In an environment of high temperature, high pressure and the presence of impurities, the catalytic particles are prone to carbon deposition and other phenomena. Carbon deposition will cover the surface of the catalytic particles, hindering the contact between the reactants and the active sites.

[0005] Therefore, it is necessary to provide a methanol reforming hydrogen production power supply system to solve the above problems. Summary of the Invention

[0011] Preferably, a second separation member is arranged in the exhaust pipe, and the second separation member is used for blocking the passage of hydrogen.

[0012] Preferably, a heat exchanger is arranged on one side of the power supply assembly, a heat exchange cylinder is sleeved outside the liquid supply pipe, and a heat exchange loop is formed by connecting the heat exchange cylinder and the heat exchanger through a first heat pipe and a second heat pipe.

There is a gap between the contraction part and the nozzle, and the contraction part, the straight-through part and the expansion part are integrally formed with the inner wall of the mixing chamber.

[0014] Preferably, the contraction part, the straight-through part and the expansion part are all made of elastic materials.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The terms "first", "second", etc. in the specification, claims and above-mentioned drawings of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, which is only a way of distinguishing when describing objects with the same attributes in the embodiments of the present application. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, so that a process, method, system, product or device including a series of units does not have to be limited to those units, but may include other units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0021] Embodiment: Please refer to Figures 1-4, in an embodiment of the present invention, a power supply system using methanol reforming to produce hydrogen and electricity is provided, including: A processing chamber 3, with a reforming chamber 5 and a mixing chamber 6 arranged at intervals inside it; A first partition plate 4, fixedly connected between the reforming chamber 5 and the mixing chamber 6, and jointly defining a temperature control space and a gas buffer space with the inner wall of the processing chamber 3. Among them, the temperature control space is surrounded by the first partition plate 4, the reforming chamber 5, and the processing chamber 3, and the gas buffer space is surrounded by the first partition plate 4, the mixing chamber 6, and the processing chamber 3; A steam generator 1, whose gas outlet end is connected to the gas buffer space; A liquid supply pipe 2, one end of which is connected to an external methanol supply component, and the other end extends into the processing chamber 3 and forms a nozzle 17; Catalytic particles, filled in the reforming chamber 5; Among them, the gas outlet end of the reforming chamber 5 is successively connected to a gas outlet seat 7, a separation component 8, and a power supply component 9. A net is provided in the gas outlet seat 7, and the net is used to intercept catalytic particles.

[0022] During implementation, the following steps are included: Step 1: The external methanol supply component transports methanol into the processing chamber 3 through the liquid supply pipe 2. The methanol is ejected from the nozzle 17 at the other end of the liquid supply pipe 2 and enters the reforming chamber 5.

[0023] Step 2: The steam generator 1 generates steam. The steam enters the gas buffer space from its gas outlet end, and then enters the reforming chamber 5 to be mixed with the sprayed methanol.

[0024] Step 3: Inside the reforming chamber 5, the filled catalytic particles carry out a catalytic reforming reaction on the mixed gas of methanol and steam, converting methanol into hydrogen and other by-products (such as carbon monoxide, carbon dioxide, etc.).

[0025] Step 4: The gas generated by the reaction enters the gas outlet seat 7 from the gas outlet end of the reforming chamber 5. The net in the gas outlet seat 7 intercepts the catalytic particles that may be carried out by the gas to prevent them from entering the subsequent components.

[0026] Step 5: The gas filtered by the net enters the separation component 8. The separation component 8 separates hydrogen from the mixed gas. Of course, this link also requires appropriate temperature to separate hydrogen.

[0027] Step 6: The separated hydrogen enters the power supply component 9, and in the power supply component 9, the chemical energy of hydrogen is converted into electrical energy through a fuel cell to supply power to external devices.

[0028] In this embodiment, the reforming chamber 5 and the mixing chamber 6 are integrated in the processing chamber 3. The temperature control space and the gas buffer space are reasonably divided by the first partition plate 4, making the entire system structure compact, occupying a small space, and being convenient for installation and layout.

[0029] The temperature control space is surrounded by the first partition plate 4, the reforming chamber 5, and the processing chamber 3. This structural design is beneficial to precisely control the temperature in the reforming chamber 5. Since the reforming reaction usually needs to be carried out within a specific temperature range, good temperature control helps to improve the reaction efficiency and hydrogen production rate.

[0030] The gas buffer space is surrounded by the first partition plate 4, the mixing chamber 6, and the processing chamber 3. The steam generated by the steam generator 1 first enters the gas buffer space and then enters the mixing chamber 6, ensuring the stability of the gas composition entering the reforming chamber 5 and being beneficial to the stable progress of the reforming reaction.

[0031] This system integrates multiple functions such as methanol reforming to produce hydrogen, gas separation, and power supply, realizes the integrated conversion from methanol to electric energy, reduces intermediate links, improves energy conversion efficiency, and reduces the complexity and cost of the system.

[0032] Among them, a baffle 14 is slidably arranged along the axial direction in the reforming chamber 5. The baffle 14 is a mesh plate structure and is used to confine the catalytic particles at one end of the reforming chamber 5 adjacent to the gas outlet seat 7.

[0033] Using the baffle 14 to confine the catalytic particles in a specific area can make the reaction gas contact the catalytic particles more concentratedly, improving the efficiency and effect of the catalytic reaction. At the same time, it also helps to ensure the uniformity of the distribution of catalytic particles in the reaction area, further improving the hydrogen production rate and reaction stability.

[0034] As a mesh plate structure, the baffle 14 allows gas to pass through smoothly while confining the catalytic particles. It can prevent the catalytic particles from flowing randomly in the reforming chamber 5, reduce local reaction abnormalities caused by uneven distribution of catalytic particles, and thus enhance the stability and reliability of the entire system.

[0035] In addition, one end of the baffle 14 far from the mixing chamber 6 is connected to a flexible tube 15. The flexible tube 15 passes through the gas outlet seat 7 and is connected to a reel 16. The reel 16 is configured to adjust the extension length of the flexible tube 15.

[0036] Generally, due to the close distribution of catalytic particles, some contact points of catalytic particles cannot contact the gas, resulting in poor utilization. In this embodiment, the reel 16 is operated to release the flexible tube 15. The flexible tube 15 extends, and under the action of factors such as the self-gravity and mutual extrusion of the catalytic particles, the stacked catalytic particles will push the baffle 14 to axially move along the direction of the mixing chamber 6.

[0037] During the movement of the baffle 14, the catalytic particles become loose and redistributed. After that, the winder 16 is operated to wind up the flexible tube 15, driving the baffle 14 to move away from the mixing chamber 6, further promoting the rearrangement of the catalytic particles, adjusting the contact points between the catalytic particles, enabling more catalytic particles to fully contact the reaction gas, making the reforming reaction more complete and stable, facilitating the improvement of the purity and quality of hydrogen, and reducing the generation of by-products.

[0038] Furthermore, when the baffle 14 confines the catalytic particles to one end of the reforming chamber 5 adjacent to the gas outlet seat 7, micropores are provided on the flexible tube 15 located in the reforming chamber 5, and the flexible tube 15 is connected to an external gas supply device for introducing oxygen.

[0039] Generally, after the system operates for a period of time, it will be detected that there is a problem of carbon deposition on the catalytic particles. At this time, the external gas supply device is started, and oxygen is introduced into the reforming chamber 5 through the micropores on the flexible tube 15. Since the flexible tube 15 is located in the reforming chamber 5 and is provided with micropores, oxygen can be evenly dispersed around the catalytic particles. Under appropriate temperature and conditions, oxygen will react with the carbon deposition on the surface of the catalytic particles to convert the carbon deposition into gases such as carbon dioxide, thereby removing the carbon deposition, avoiding problems such as the decline of catalytic activity and the reduction of reaction efficiency caused by the accumulation of carbon deposition, and ensuring the performance of the catalytic particles and the stable progress of the reforming reaction.

[0040] This method of carbon deposition treatment is carried out in situ in the reforming chamber 5, without the need to take out the catalytic particles for separate treatment, greatly simplifying the operation process, reducing the downtime of the system, and improving the operating efficiency of the system.

[0041] In addition, the operating parameters of the external gas supply device, such as the flow rate and time of the introduced gas, can be flexibly controlled according to the severity of carbon deposition and the actual situation to achieve the best carbon deposition treatment effect.

[0042] In this embodiment, the separation assembly 8 includes: A separation chamber 81, one end of which is connected to the gas outlet seat 7, and the other end is connected to the power supply assembly 9 through a connecting pipe 83; A partitioning assembly, including a plurality of partitioning plates two 82 distributed at circumferential intervals, and the partitioning assembly is rotatably arranged clockwise in the separation chamber 81; An exhaust pipe 85, connected to the top of the separation chamber 81; A first separation member 84, arranged in the connecting pipe 83 for selectively passing hydrogen.

[0043] During implementation, the mixed gas (including hydrogen, carbon dioxide, carbon monoxide, etc.) generated by the reaction in the reforming chamber 5 enters the separation chamber 81 through the gas outlet seat 7. At this time, the partition plate 82 in the partition component rotates clockwise, causing the mixed gas to form a complex flow path within the separation chamber 81, increasing the chances of collision and diffusion between gas molecules.

[0044] During the flow of the mixed gas, the enriched hydrogen flows through the connecting pipe 83 to the power supply component 9. In the connecting pipe 83, the first separating member 84 plays a key role. It only allows hydrogen to pass through while blocking other potentially remaining gases within the separation chamber 81, ensuring that the gas entering the power supply component 9 is high-purity hydrogen.

[0045] After the high-purity hydrogen enters the power supply component 9, the chemical energy of the hydrogen is converted into electrical energy through devices such as fuel cells to power external devices.

[0046] It should be explained that palladium has a unique selective permeability to hydrogen. Under certain temperature and pressure conditions, hydrogen can dissolve in the palladium lattice in atomic form and rapidly diffuse to the other side of the palladium membrane, while other gases (such as carbon dioxide, carbon monoxide, etc.) are difficult to penetrate the palladium membrane. Therefore, the first separating member 84 described above can be a palladium membrane.

[0047] For example, a palladium membrane with a thickness of 50 microns is used as the first separating member 84. After the mixed gas enters the connecting pipe 83, hydrogen quickly passes through the palladium membrane and enters the power supply component 9, while other gases are blocked on one side of the palladium membrane and are finally discharged through the waste gas pipe 85. At a working temperature of 300 °C, the hydrogen permeation rate of this palladium membrane can reach 50 mL - 100 mL / (cm²·min), and the hydrogen purity can reach over 99.999%, effectively ensuring the efficient operation of the power supply component 9.

[0048] In this embodiment, a second separating member is provided in the waste gas pipe 85, and the second separating member is used to block the passage of hydrogen.

[0049] The main function of the second separating member is to block the passage of hydrogen, ensuring that the gas discharged from the waste gas pipe 85 is mainly waste gases such as carbon dioxide and carbon monoxide. For example, high-efficiency interception can be achieved through a crystalline porous composite membrane or a gradient pore size carbon molecular sieve, and CO or CO 2 selective passage, which will not be elaborated here. 2 Of course, in an ideal state, since hydrogen has been separated from the first separating member 84, the second separating member may not be provided at this time.

[0050]

[0051] ​In this embodiment, a heat exchanger 10 is provided on one side of the power supply assembly 9. A heat exchange cylinder 13 is sleeved outside the liquid supply pipe 2. A heat exchange loop is formed by connecting the heat exchange cylinder 13 and the heat exchanger 10 through a first heat pipe 11 and a second heat pipe 12. Of course, a pump body and a valve body also need to be provided in the heat exchange loop, which will not be elaborated here.

[0052] When the heat generated by the power supply assembly 9 is relatively large, the heat exchanger 10 can transfer the excess heat back to the heat exchange cylinder 13 through the second heat pipe 12, and then transfer it to the methanol solution in the liquid supply pipe 2 to preheat the methanol solution, reducing the energy required for external heating and realizing the recovery and reuse of heat.

[0053] In this embodiment, a part of the nozzle 17 extends into the mixing chamber 6. Along the gas flow direction, a contraction part 18, a straight flow part 19, and an expansion part 20 are sequentially provided on the inner wall of the mixing chamber 6. There is a gap between the contraction part 18 and the nozzle 17, and the contraction part 18, the straight flow part 19, and the expansion part 20 are integrally formed with the inner wall of the mixing chamber 6.

[0054] In addition, the contraction part 18, the straight flow part 19, and the expansion part 20 are all made of elastic materials.

[0055] Among them, a part of the nozzle 17 extending into the mixing chamber 6 enables the methanol ejected from the nozzle 17 to enter the mixing chamber 6 at a specific angle and in a specific manner, which is conducive to the full mixing of methanol and steam. The way of partial extension can prevent the nozzle 17 from extending too deeply and affecting the gas flow, while ensuring that the methanol can be directly sprayed into the mixing area.

[0056] Through the reasonable design of the contraction part 18, the straight flow part 19, and the expansion part 20, and the application of elastic materials, different degrees of mixing of methanol and steam can be achieved at different stages. The contraction part 18 accelerates the gas flow and sucks in steam, the straight flow part 19 ensures stable mixing of the gas, and the expansion part 20 makes the mixing more sufficient and stable, thereby improving the mixing effect of methanol and steam and being conducive to the efficient progress of the subsequent reforming reaction.

[0057] Further, an adjustment groove 21 is provided in the straight flow part 19, and an elastic member 22 is arranged in the adjustment groove 21. The elastic member 22 is used to provide radial support for the straight flow part 19, and the elastic modulus of the elastic member 22 is less than the elastic modulus of the contraction part 18, the straight flow part 19, and the expansion part 20.

[0058] Generally speaking, the adjustment groove 21 can be in a strip shape, a circular shape, or other suitable shapes to adapt to the installation and deformation requirements of the elastic member 22.

[0059] The adjustment groove 21 provides an installation space for the elastic member 22, enabling the elastic member 22 to function in the DC portion 19. At the same time, the existence of the adjustment groove 21 also changes the local structure of the DC portion 19, enabling it to better adapt to the flow changes of the gas under different working conditions.

[0060] The elastic member 22 is made of a material with an elastic modulus smaller than that of the contraction portion 18, the DC portion 19, and the expansion portion 20. This means that the elastic member 22 has better flexibility and deformation ability, can undergo large deformations under a small external force, and can quickly return to its original state after the external force is removed.

[0061] Due to the small elastic modulus of the elastic member 22, it can be deformed under the pressure generated by the gas flow, thereby changing the local channel cross-sectional area around the adjustment groove 21. This change can further adjust the flow rate and flow direction of the gas, making the mixing of methanol and steam in the DC portion 19 more uniform.

[0062] For example, when the gas flow rate is large, the elastic member 22 is deformed by the force, and the channel cross-sectional area around the adjustment groove 21 increases, reducing the gas flow rate and allowing methanol and steam more time to mix; when the gas flow rate is small, the elastic member 22 returns to its original state, the channel cross-sectional area decreases, increasing the gas flow rate, and ensuring the sufficiency of mixing. In this way, the mixing uniformity of methanol and steam in the DC portion 19 is further improved.

[0063] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
