Description

Technical Field

[0001] This invention relates to the field of hydrogen energy industry technology, specifically to a combined heat and power (CHP) system for residential buildings based on microwave-induced alcohol hydrogen production. Background Technology

[0002] As the global energy structure transitions towards a low-carbon model, residential buildings, as the core energy consumption scenario, face an increasingly urgent need for clean, stable, and integrated energy supply systems. Currently, household energy consumption mainly relies on grid power and fossil fuel heating (such as gas boilers), but this faces many prominent problems in practical applications: during extreme weather or grid maintenance, urban residences often experience power outages, affecting lighting, appliance operation, and winter heating; in rural or remote areas, insufficient grid coverage leads to poor stability of household electricity supply, and the inconvenience of gas transportation makes it difficult to guarantee heating and hot water supply. Meanwhile, traditional gas boilers produce pollutants such as nitrogen oxides during combustion, which does not meet the requirements for green and environmentally friendly residential use, while distributed renewable energy power supply systems such as solar and wind power are significantly affected by weather and seasons, exhibiting intermittent power supply defects and failing to meet the continuous energy needs of households.

[0003] To address the aforementioned issues, alcohol reforming hydrogen production technology is gradually emerging as a potential solution for residential distributed energy supply due to its advantages such as easy storage of raw materials and a clean hydrogen production process. Existing alcohol hydrogen production equipment is mostly large-scale industrial-grade equipment. While it can produce hydrogen, it is difficult to adapt to the space constraints and convenient usage requirements of residential scenarios. Most of this equipment lacks modular design, resulting in low integration of raw material supply, mixing, reaction, and purification processes, cumbersome installation and maintenance, and a lack of precise control mechanisms specifically for residential use.

[0004] In the core microwave catalytic reforming process, existing technologies face a key bottleneck: microwave catalytic reactions rely on the high activity of the catalyst, but during the reaction, the catalyst surface is prone to deactivation due to carbon buildup covering active sites. Traditional hydrogen production equipment lacks a dedicated catalyst regeneration structure, requiring users to frequently replace the catalyst. This not only increases operating costs but also leads to raw material waste and operational inconvenience, severely hindering the widespread adoption of microwave catalytic hydrogen production technology in residential settings. Therefore, we need to propose a residential multi-generation system based on microwave-induced alcohol hydrogen production. Summary of the Invention

[0005] The purpose of this invention is to provide a residential multi-generation system based on microwave-induced alcohol hydrogen production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A residential power generation system based on microwave-induced alcohol hydrogen production includes: A raw material supply organization, which includes alcohol storage tanks and deionized water storage tanks; A mixing tank, on which a mixing assembly is installed, and an alcohol storage tank and a deionized water storage tank are connected to the mixing tank via a first connecting assembly; A reforming reaction mechanism, the reforming reaction mechanism including a microwave generating box and a catalytic component disposed inside it, the mixing tank being connected to the microwave generating box via a second connecting component; The product purification mechanism includes an adsorption device for purifying hydrogen.

[0008] Preferably, each of the first connecting components includes two outlet pipes, a first connecting pipe, and a first water pump. One end of each of the two outlet pipes is connected to an alcohol storage tank and a deionized water storage tank, respectively. The other end of each outlet pipe is connected to the first connecting pipe via a tee. The other end of the first connecting pipe is connected to a mixing tank. The first water pump is connected to the first connecting pipe. A flow control valve is installed on each of the two outlet pipes. The second connection assembly includes a second water pump and a second connecting pipe. The two ends of the second connecting pipe are respectively connected to a mixing tank and a microwave generator box, and the second water pump is connected to the second connecting pipe.

[0009] Preferably, the water outlet pipe is equipped with a primary coarse filter and a secondary fine filter, and the primary coarse filter and the secondary fine filter are coated with a nano-antibacterial coating.

[0010] Preferably, the mixing component includes a drive motor and a mixing paddle, the mixing paddle being rotatably connected to the mixing tank, the drive motor being mounted on the mixing tank, and the output end of the drive motor being connected to the extension end of the mixing paddle that passes through the mixing tank.

[0011] Preferably, the catalytic component includes a honeycomb ceramic catalyst support and a microwave generator, both of which are installed inside a microwave generating chamber, and a molecular sieve composite catalyst is loaded on the honeycomb ceramic catalyst support; The microwave generator box is equipped with a temperature sensor and an infrared gas sensor, and the inner cavity of the microwave generator box is made of stainless steel.

[0012] Preferably, the catalyst regeneration assembly includes a nitrogen tank, a gas filling pipe, a first electrically controlled valve, an annular pipe, and several nozzles. The nitrogen tank is installed on a microwave generator box, and the two ends of the gas filling pipe are connected to the nitrogen tank and the annular pipe, respectively. The first electrically controlled valve is installed on the gas filling pipe, the annular pipe is installed inside the microwave generator box, and several nozzles are installed on the annular pipe.

[0013] Preferably, the adsorption device includes three adsorption towers, and the three adsorption towers contain molecular sieve adsorbent.

[0014] Preferably, a pressure sensor is installed inside the hydrogen buffer tank, and an exhaust pipe is installed on the hydrogen buffer tank, with a pressure relief valve installed on the exhaust pipe.

[0015] Preferably, a protective box is installed on the microwave generator box, and a PLC controller is installed inside the protective box. The PLC controller is electrically connected to the first solenoid valve, the second solenoid valve, the flow control valve, the liquid level sensor, the first water pump, the second water pump, the drive motor, the microwave generator, the temperature sensor, the infrared gas sensor, the pressure sensor, and the pressure relief valve.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention effectively overcomes the technical bottleneck of easy catalyst deactivation and frequent replacement in existing alcohol-to-hydrogen equipment by adding a catalyst regeneration component to the reforming reaction mechanism. In the prior art, the catalyst surface is prone to carbon buildup covering active sites during microwave catalytic reaction, leading to decreased activity. Users need to regularly disassemble the equipment to replace the catalyst, which not only increases consumable costs and maintenance difficulty but also affects the continuity of residential power supply due to equipment downtime. However, the catalyst regeneration component of this invention can remove carbon buildup on the catalyst surface through specific processes (such as high-temperature purging, inert gas activation, etc.) without disassembling the catalyst component, restoring its catalytic activity, significantly extending the catalyst's service life, reducing replacement frequency and maintenance costs, and avoiding power interruption caused by catalyst replacement. It is more suitable for the needs of residential scenarios for equipment convenience and power supply stability.

[0017] 2. This invention integrates the raw material supply mechanism, mixing tank, reforming reaction mechanism, and product purification mechanism through modular design, effectively solving the problems of large size, low integration, and difficulty in adapting to residential spaces in existing industrial-grade hydrogen production equipment. Existing alcohol-based hydrogen production equipment is mostly an integral structure with complex connections between functional components, a large footprint, and requires on-site installation by a professional team, making it inflexible for limited spaces such as residential balconies and equipment rooms. In contrast, this invention breaks down raw material supply (alcohol storage tank, deionized water storage tank), raw material mixing (mixing tank with mixing components), catalytic reaction (microwave generator and catalytic components), and product purification (adsorption device and hydrogen buffer tank) into interconnected functional modules. Each module is compact, easy to install, and can be flexibly combined and placed according to the layout of residential spaces. Simultaneously, the modular design facilitates the inspection and replacement of individual modules, reducing maintenance difficulty and better meeting the requirements of residential scenarios for equipment space adaptability and ease of operation.

[0018] 3. This invention, by constructing an integrated "hydrogen production-purification-storage" process and combining it with multi-generational power supply scenarios, effectively improves the stability and environmental friendliness of residential energy supply, overcoming the shortcomings of intermittent power supply from existing distributed energy sources (such as solar and wind power) and the high pollution levels of traditional fossil fuel heating. In existing residential energy supply systems, solar and wind power are prone to power outages due to weather conditions, and traditional gas boiler heating produces pollutants. In contrast, this invention uses alcohols as raw materials and employs a clean, pollutant-free hydrogen production process through microwave catalytic reforming. The generated hydrogen is purified by an adsorption device and stored in a hydrogen buffer tank, providing stable energy for residential power, heating, and hot water supply. Even in the event of a power outage or extreme weather, the hydrogen buffer tank ensures basic energy needs are met, achieving low-carbon and continuous residential energy supply, better meeting the residential demand for clean and stable energy supply.

[0021] 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.

[0022] Example: Please see Figures 1-5 The present invention provides a technical solution: A residential power generation system based on microwave-induced alcohol hydrogen production includes: The raw material supply mechanism includes an alcohol storage tank 1 and a deionized water storage tank 2. Both the alcohol storage tank 1 and the deionized water storage tank 2 are equipped with liquid level sensors 8, and both the alcohol storage tank 1 and the deionized water storage tank 2 are equipped with feed pipes 9, and the feed pipes 9 are equipped with sealing caps 10. The microwave-induced alcohol-to-hydrogen production system for residential use can be installed in basements, garages, or courtyards. The sealing caps 10 of alcohol storage tank 1 and deionized water storage tank 2 are opened, and alcohol and deionized water are added through the feed pipes 9 until the level sensor 8 detects that the raw materials have reached the preset storage level. Then, adding continues and the sealing caps 10 are closed. During this process, alcohol storage tank 1 and deionized water storage tank 2 serve as raw material reserve units. The level sensor 8 monitors the remaining raw material level in real time to prevent system shutdown due to insufficient raw materials; this is the basic application of the raw material supply principle. Subsequently, the system self-test program is initiated by the PLC controller 33 inside the protective box 32. The PLC controller 33 sends signals to the level sensor 8, temperature sensor 22, infrared gas sensor 23, and pressure sensor 30 to confirm that each sensor is providing normal feedback data. Simultaneously, it checks that the first solenoid valve 26, the second solenoid valve 6, and the pressure relief valve 31 are in the closed state, and that the first water pump 13, the second water pump 14, the drive motor 18, and the microwave generator 21 are in standby mode. Here, the PLC controller 33 and each sensor form a preliminary collaboration of "data acquisition-analysis and judgment". The PLC controller 33 acts as the central hub, and judges the initial state of the system by receiving feedback data from the sensors, avoiding the omissions of manual inspection and completing the startup preparation.

[0023] The mixing tank 3 is equipped with a mixing assembly, which includes a drive motor 18 and a mixing paddle 19. The mixing paddle 19 is rotatably connected to the mixing tank 3. The drive motor 18 is mounted on the mixing tank 3, and the output end of the drive motor 18 is connected to the extension end of the mixing paddle 19 that passes through the mixing tank 3. The alcohol storage tank 1 and the deionized water storage tank 2 are connected to the mixing tank 3 through a first connecting assembly. The reforming reaction mechanism includes a microwave generator box 4 and a catalytic component installed inside it. The mixing tank 3 is connected to the microwave generator box 4 through a second connecting component. The first connecting component includes two water outlet pipes 11, a first connecting pipe 12, and a first water pump 13. One end of the two water outlet pipes 11 is connected to the alcohol storage tank 1 and the deionized water storage tank 2, respectively. The other end of the water outlet pipes 11 is connected to the first connecting pipe 12 through a tee. The other end of the first connecting pipe 12 is connected to the mixing tank 3. The first water pump 13 is connected to the first connecting pipe 12. A flow control valve 35 is installed on each of the two water outlet pipes 11. A primary coarse filter screen 16 and a secondary fine filter screen 17 are installed on the water outlet pipes 11, and the primary coarse filter screen 16 and the secondary fine filter screen 17 are coated with a nano antibacterial coating. The raw material mixing parameters are set by the PLC controller 33, which then sends start commands to the first water pump 13 and the drive motor 18. The first water pump 13 operates, transporting the raw materials from the alcohol storage tank 1 and the deionized water storage tank 2 through the outlet pipe 11 to the first connecting pipe 12. The flow control valve 35 controls the addition amount of alcohol and deionized water respectively. The raw materials pass through a primary coarse filter 16 and a secondary fine filter 17 in the outlet pipe 11 (to remove impurities) before converging through a three-way valve into the mixing tank 3. Due to the adoption of the raw material pretreatment structure of "primary coarse filter 16 + secondary fine filter 17 + nano-antibacterial coating," a dual removal effect of impurities and microorganisms is achieved, thus solving the problems of impurities clogging the catalytic components and microbial contamination of the raw materials leading to a decrease in hydrogen production efficiency in existing systems. This ensures the stability of the subsequent reforming reaction and the purity of hydrogen, directly demonstrating the principle and beneficial effects of raw material pretreatment. Simultaneously, the drive motor 18 drives the mixing paddle 19 to rotate within the mixing tank 3, stirring and mixing the raw materials. This mechanical stirring breaks up the material stratification, ensuring a uniform mixture of alcohol and deionized water. This provides a stable raw material ratio for subsequent reforming reactions, preventing a decrease in reaction efficiency due to uneven mixing. This is the core application of the raw material mixing principle. Once the mixture is uniformly mixed, the PLC controller 33 receives a preset mixing completion signal from the mixing tank 3 (e.g., a set stirring time), and controls the first water pump 13 and drive motor 18 to stop operating. During this stage, the PLC controller 33, the first water pump 13, and the drive motor 18 form a collaborative closed loop of "instruction sending-execution-feedback-stop," precisely controlling the mixing process and achieving automated system control. This reduces the operational difficulty for residential users, adapting to the convenient usage needs of home environments, and demonstrating the beneficial effects of the collaboration between the PLC controller 33 and the execution components.

[0024] The PLC controller 33 sends start commands to the second water pump 14 and the microwave generator 21. The second water pump 14 starts, transporting the mixed raw materials in the mixing tank 3 to the microwave generator box 4 via the second connecting pipe 15. The microwave generator 21 starts, releasing microwave energy to the honeycomb ceramic catalyst support 20, activating the molecular sieve composite catalyst loaded on the support, and promoting the reforming reaction of the mixed raw materials to generate hydrogen-containing gas. This is the key step in the principle of microwave catalytic reforming—microwave energy penetrates the honeycomb ceramic catalyst support 20, activates the active sites of the molecular sieve composite catalyst, reduces the activation energy of the reforming reaction of the raw materials, and promotes the efficient conversion of the raw materials into hydrogen-containing gas. During this process, the temperature sensor 22 monitors the temperature inside the microwave generator box 4 in real time, and the data is synchronously transmitted to the PLC controller 33. If the temperature exceeds the preset range, the PLC controller 33 automatically adjusts the power of the microwave generator 21 to ensure stable reaction. Here, the temperature sensor 22 works in conjunction with the PLC controller 33 and the microwave generator 21. The temperature sensor 22 collects reaction temperature data and transmits it to the PLC controller 33. The PLC controller 33 adjusts the power of the microwave generator 21 according to the data to maintain a stable reaction temperature, ensuring hydrogen production efficiency and safety. This forms a closed-loop collaboration of "data acquisition - analysis and judgment - execution and control", avoiding human operation errors and further demonstrating the central control role of the PLC controller 33 and the advantages of component collaboration.

[0025] The second connection assembly includes a second water pump 14 and a second connecting pipe 15. The two ends of the second connecting pipe 15 are respectively connected to the mixing tank 3 and the microwave generator box 4. The second water pump 14 is connected to the second connecting pipe 15. The product purification mechanism includes an adsorption device for purifying hydrogen. A microwave generator box 4 is connected to the adsorption device via a first connecting gas pipe 5, and a second electrically controlled valve 6 is installed on the first connecting gas pipe 5. The adsorption device is connected to a hydrogen buffer tank 34 via a second connecting gas pipe 7. A pressure sensor 30 is installed inside the hydrogen buffer tank 34. An exhaust pipe 36 is installed on the hydrogen buffer tank 34, and a pressure relief valve 31 is installed on the exhaust pipe 36. The adsorption device includes three adsorption towers 29, and each of the three adsorption towers 29 contains a molecular sieve adsorbent. When the infrared gas sensor 23 detects that the hydrogen-containing gas has reached the preset production amount, the PLC controller 33 controls the second electrically controlled valve 6 to open, and the hydrogen-containing gas enters the adsorption device through the first connecting gas pipe 5. The three adsorption towers 29 inside the adsorption device use built-in molecular sieve adsorbents to selectively adsorb and remove unreacted raw materials, byproducts, and other impurities from the hydrogen-containing gas, purifying it to obtain high-purity hydrogen. This is an application of the product purification principle. The purified hydrogen is transported to the hydrogen buffer tank 34 for storage through the second connecting gas pipe 7. The pressure sensor 30 monitors the pressure inside the buffer tank in real time and feeds it back to the PLC controller 33. If the pressure exceeds the preset value, the PLC controller 33 controls the pressure relief valve 31 to open, releasing excess pressure through the exhaust pipe 36 to ensure storage safety. The adsorption unit, consisting of three adsorption towers 29 and a hydrogen buffer tank 34 with a pressure relief valve 31, achieves efficient purification and safe storage of hydrogen. This solves the problems of insufficient hydrogen purity and uncontrollable storage pressure in traditional hydrogen production systems, providing a high-purity and stable hydrogen source for subsequent combined heat and power (CHP) scenarios such as residential power supply, heating, and hot water supply, ensuring the operational reliability of the CHP system. This is the core beneficial effect of this stage. Simultaneously, the three adsorption towers 29 of the adsorption unit are controlled by a PLC controller 33 to achieve alternating adsorption and regeneration, continuously outputting high-purity hydrogen. The hydrogen buffer tank 34 receives and stores hydrogen in real time. When subsequent energy supply units (such as fuel cells) require hydrogen, the buffer tank can stably output hydrogen, avoiding hydrogen supply interruptions caused by the switching of the adsorption unit. This achieves continuous synergy between purification, storage, and energy supply, demonstrating the collaborative effect of the adsorption unit and the hydrogen buffer tank 34. When the gas pressure inside the hydrogen buffer tank 34 reaches the preset storage amount, the PLC controller 33 controls the second electronic control valve 6 to close, suspending the hydrogen delivery, once again highlighting the precise control of the PLC controller 33 over the entire process.

[0026] The reforming reaction mechanism also includes a catalyst regeneration component for realizing catalyst regeneration. The catalyst component includes a honeycomb ceramic catalyst support 20 and a microwave generator 21. Both the honeycomb ceramic catalyst support 20 and the microwave generator 21 are installed in the microwave generator box 4. The molecular sieve composite catalyst is loaded on the honeycomb ceramic catalyst support 20. The microwave generator box 4 is equipped with a temperature sensor 22 and an infrared gas sensor 23. The inner cavity of the microwave generator box 4 is made of stainless steel. The catalyst regeneration component includes a nitrogen tank 24, a gas filling pipe 25, a first electrically controlled valve 26, an annular pipe 27, and several nozzles 28. The nitrogen tank 24 is installed on the microwave generator box 4. The two ends of the gas filling pipe 25 are connected to the nitrogen tank 24 and the annular pipe 27, respectively. The first electrically controlled valve 26 is installed on the gas filling pipe 25. The annular pipe 27 is installed inside the microwave generator box 4. Several nozzles 28 are installed on the annular pipe 27.

[0027] When the system runs for a preset time (or the infrared gas sensor 23 detects a decrease in hydrogen production efficiency and determines that the catalyst needs regeneration), the PLC controller 33 first controls the second water pump 14 and microwave generator 21 to stop operating and closes the second electronic control valve 6. Then, it controls the first electronic control valve 26 to open, and nitrogen from the nitrogen tank 24 is transported to the annular pipe 27 via the gas filling pipe 25. The nitrogen is then evenly sprayed onto the honeycomb ceramic catalyst carrier 20 through several nozzles 28 on the annular pipe 27. Simultaneously, the PLC controller 33 adjusts the microwave generator 21 to output low-power microwaves, which, in conjunction with nitrogen purging, remove carbon deposits from the catalyst surface. During this process, the nitrogen released from the nitrogen tank 24 forms a uniform purging airflow through the annular pipe 27 and the nozzles 28. Combined with low-power microwave heating, this causes the carbon deposits on the catalyst surface to react with the nitrogen or be purged off, restoring catalyst activity and achieving in-situ catalyst regeneration. This is an application of the catalyst regeneration principle. The annular pipe 27 and nozzle 28 of the catalyst regeneration assembly are arranged around the honeycomb ceramic catalyst carrier 20, which can uniformly deliver nitrogen to the catalyst surface. The microwave generator 4 outputs low-power microwaves during the regeneration stage to provide a suitable temperature for the removal of carbon deposits on the catalyst surface. The two work together to achieve efficient regeneration through "nitrogen purging + microwave assistance," avoiding the problem of incomplete regeneration caused by single purging or heating, demonstrating the synergistic effect of the catalyst regeneration assembly and the microwave generator 4. Because the catalyst regeneration assembly, composed of nitrogen tank 24, annular pipe 27, and nozzle 28, operates in conjunction with the microwave generator 4, in-situ catalyst regeneration is achieved. This solves the problems of easy carbon buildup and deactivation of catalysts in existing systems, requiring frequent disassembly and replacement, extending catalyst lifespan, reducing maintenance costs and downtime, and improving the system's continuous power supply capability. This is a significant beneficial effect of the catalyst regeneration stage. After regeneration is completed, the PLC controller 33 closes the first electronic control valve 26 and the microwave generator 21, and the system can re-enter the feedstock mixing-reforming hydrogen production cycle.

[0028] During microwave catalytic reactions, the catalyst surface is prone to carbon buildup that covers active sites, leading to a decrease in activity. Users need to periodically disassemble the equipment to replace the catalyst, which not only increases consumable costs and maintenance difficulty but also affects the continuity of residential power supply due to equipment downtime. However, the catalyst regeneration component of this invention can remove carbon buildup on the catalyst surface through specific processes (such as high-temperature purging and inert gas activation) without disassembling the catalyst component, restoring its catalytic activity, significantly extending the catalyst's lifespan, reducing replacement frequency and maintenance costs, and avoiding power interruptions caused by catalyst replacement. This is more suitable for the needs of residential scenarios for equipment convenience and power supply stability.

[0029] In the above embodiment, a protective box 32 is installed on the microwave generator box 4, and a PLC controller 33 is installed inside the protective box 32. The PLC controller 33 is electrically connected to the first solenoid valve 26, the second solenoid valve 6, the flow control valve 35, the liquid level sensor 8, the first water pump 13, the second water pump 14, the drive motor 18, the microwave generator 21, the temperature sensor 22, the infrared gas sensor 23, the pressure sensor 30, and the pressure relief valve 31.

[0030] It should be noted that the specific models and specifications of the PLC controller 33, the first solenoid valve 26, the second solenoid valve 6, the flow control valve 35, the liquid level sensor 8, the first water pump 13, the second water pump 14, the drive motor 18, the microwave generator 21, the temperature sensor 22, the infrared gas sensor 23, the air pressure sensor 30, and the pressure relief valve 31 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
