Description

Technical Field

[0001] This invention relates to the fields of renewable energy, hydrogen economy, and carbon negative emissions technology. Specifically, it relates to a carbon negative combined heat and power system based on a modular cascade architecture, capable of efficiently converting wind energy into electricity, hydrogen, heat, cold energy, fresh water, and various high-value-added chemicals, and achieving direct air carbon capture. This invention falls under the technical fields of combining F03D9 / 00 (wind turbines and other equipment combinations), C25B1 / 04 (hydrogen production by water electrolysis), B01D53 / 14 (gas separation and carbon capture), and C02F1 / 04 (seawater desalination) in the International Patent Classification (IPC). It is applicable to diverse scenarios such as off-grid islands, border outposts, coastal chemical industrial parks, inland arid regions, shipboard platforms, and civil buildings pursuing zero-carbon goals, providing integrated energy, water resources, and carbon balance solutions. Background Technology

[0002] With the advancement of the global energy transition and the "dual carbon" goal, wind energy, as a clean and renewable energy source, is being used more and more widely, and technologies such as wind-powered hydrogen production, seawater desalination, and carbon capture have also made independent progress. However, existing technological solutions still face many systemic bottlenecks: Limited functionality and low integration: Existing composite energy systems often only solve a single problem or involve simple combinations, such as single wind power generation, wind-solar hybrid systems, or independent seawater desalination units. There is a lack of systematic and in-depth integration of wind energy capture, high-efficiency energy grade separation, hydrogen production, carbon capture, seawater desalination, and resource utilization, resulting in low overall energy utilization efficiency and long investment payback periods.

[0003] Energy fluctuations and conversion bottlenecks: The intermittency and volatility of wind energy directly affect the continuity and efficiency of downstream processes such as hydrogen production and carbon capture. Traditional solutions struggle to fundamentally mitigate the fluctuations in airflow energy. Simultaneously, there is a lack of an "energy hub" device capable of providing stable pressure and gas sources for diverse downstream applications while simultaneously generating controllable cold and heat flow, resulting in insufficient utilization of energy quality.

[0004] Lack of carbon-negative measures and difficulties in coupling: Most existing wind power systems remain at the "zero-carbon" level, lacking proactive and efficient carbon-negative emission reduction measures. Direct air carbon capture technology has high energy consumption, especially thermal regeneration, which restricts its economical deep integration with renewable energy systems.

[0005] Low resource utilization and weak intelligent control: The concentrated brine after seawater desalination is often directly discharged, causing environmental pollution and resource waste. At the same time, the control strategies of existing systems mostly focus on basic monitoring or single-objective optimization, lacking intelligent dynamic scheduling capabilities based on real-time fusion of multi-source signals, and thus failing to optimize the overall energy efficiency and economy of the system under fluctuating inputs and diverse demands.

[0006] The applicant has conducted in-depth research and development and patent applications on modular wind power systems, including modular cascaded wind power heating, cooling, electricity and water systems, integrated seawater resource utilization systems, and systems that initially combine hydrogen production and carbon capture concepts. While these prior solutions have made progress in modular architecture, energy separation, and diversified applications, they have not fundamentally solved the constraints of wind energy volatility on downstream high-stability processes (such as efficient electrolysis for hydrogen production and carbon capture), nor have they proposed a dynamic scheduling intelligent hub that integrates digital twin and blockchain technologies to achieve optimal global energy efficiency and economics. In particular, there is a lack of an intelligently controllable "pneumatic booster module" located between the energy convergence and separation stages to ensure the absolute stability of the inlet conditions of the energy separation module, thereby laying the foundation for the efficient and stable operation of the entire system. Summary of the Invention

[0015] Preferably, the pneumatic booster module can operate in a mechanical booster path, an electric booster path, or a combination of both, and is dynamically adjusted by the intelligent control center according to the downstream pressure demand.

[0016] Beneficial effects Compared with the prior art, the present invention has the following significant advantages: 1. High integration and architectural innovation: A complete modular cascade architecture of "wind energy aggregation - cascade convergence - (aerodynamic boosting) - energy separation - diversified applications - intelligent control" is proposed, which deeply couples distributed technologies and realizes a closed-loop cycle of energy and matter.

[0017] 2. Excellent energy efficiency and stability: Through the dual pressure enhancement and stabilization mechanism of cascade convergence and aerodynamic pressurization, the industry problem of severe performance degradation of vortex tubes under low pressure and fluctuating airflow input is fundamentally solved, providing a high-quality and stable cold and heat source for downstream applications, and significantly improving the stability and overall efficiency of energy separation.

[0018] 3.

[0021] 6. Finally, this invention constructs an "active-passive combined" energy security system, significantly improving the system's engineering practicality and operational reliability. By introducing system-level backup electric compressors, electric heaters, and electric chillers, and linking them with the intelligent control center, it ensures that core application units (such as carbon capture and hydrogen production) can still operate continuously and stably under optimal parameters even when wind energy input experiences extreme fluctuations or downstream demand changes abruptly.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] (I) Overview of the core working principle of the system The core innovation of this invention lies in constructing a cascaded energy flow path of "capture-stabilization (boosting)-separation-intelligent distribution". After natural wind energy is captured by the wind energy aggregation module 1, it first enters the cascaded convergence module 2, where preliminary pressurization and gas-liquid separation are achieved through multi-stage swirling flow, effectively overcoming the fluctuation and impurity problems of wind. Subsequently, the airflow can optionally enter the aerodynamic boosting module 3 for secondary pressure enhancement and stabilization. This step is crucial, as it provides stable and high-pressure inlet conditions for the energy separation module 4 (vortex tube), significantly improving the efficiency of heat and cold separation. The high-grade heat and cold energy obtained from the separation is dynamically and precisely distributed by the intelligent control center 6 to units such as power generation, hydrogen production, desalination, and carbon capture according to diverse needs, realizing the efficient utilization of all grades of wind energy and the carbon-negative operation of the system.

[0026] The intelligent control center 6 is the "intelligent brain" of the entire system. Its core lies in the deep integration of hardware modules through software algorithms. The digital twin module 601 constructs physical models of each system component and merges them with real-time collected operational data to form a virtual mirror that evolves synchronously with the physical system. This digital twin is used to execute model predictive control algorithms, which, based on the current system state and short-term future predictions, continuously optimize operational instructions within future time windows, thereby achieving optimal global energy efficiency under multi-objective dynamic scheduling. The blockchain metering module 602 utilizes its immutable and traceable technical characteristics to automatically record, verify, and execute energy output, consumption, and carbon quota transfer based on real-time data through smart contracts, providing a reliable and efficient technical foundation for the system's participation in the energy market and carbon trading.

[0027] (II) Implementation Example of Basic System Workflow like Figure 1 , Figure 3 , Figure 12 As shown, the system of the present invention includes a wind energy aggregation module 1, a cascaded aggregation module 2, a pneumatic boosting module 3, an energy separation module 4, a multi-application module 5, and an intelligent control center 6. The specific workflow is as follows: 1. Wind Energy Capture and Preliminary Treatment: Natural wind is captured by the annular compartments of the inflatable wind collector 101, achieving omnidirectional wind collection. The airflow is delivered to the cascaded converging module 2 via the throat duct 114. The airflow anti-backflow plate 103 can be opened and closed by mechanical response (such as a hinged one-way valve) or by the intelligent control center 6 based on the air pressure sensor signal, to prevent airflow backflow and system instability.

[0028] 2. Cascaded Convergence and Gas-Liquid Separation: The airflow enters the cascaded convergence module 2, which consists of at least two wind energy collection devices 202 and 203 connected in series. The tangential inlets 204 of all devices are configured to rotate in the same direction globally, achieving initial pressurization through the centrifugal effect of swirling flow. Simultaneously, this module integrates a highly efficient gas-liquid separation function, capable of removing most of the liquid water and particulate matter from the airflow, providing a clean air source for downstream applications.

[0029] 3. Pneumatic Boosting and Pressure Stabilization: The purified airflow enters the pneumatic boosting module 3. The intelligent control center 6 intelligently selects and activates the mechanical boosting path, the electric boosting path, or a combination of both, based on the inlet pressure requirements of the energy separation module 4, to boost and stabilize the airflow pressure, ensuring low output pressure fluctuations. The system also includes a backup electric compressor 608 to provide backup when the main boosting path cannot meet the requirements.

[0030] 4. Energy Separation and Diverse Application Distribution: After stable pressurization, the airflow enters the vortex tube 401 of the energy separation module 4, where it is separated into hot-end airflow flowing out from the hot-end outlet 402 and cold-end airflow flowing out from the cold-end outlet 403. The intelligent control center 6 dynamically distributes the hot-end and cold-end airflows to at least two units in the diversified application module 5 through corresponding valve groups such as the control mode switching valve group 603, the first three-way solenoid valve 604, and the second three-way solenoid valve 605. When the system's internal heating and cooling energy supply is insufficient, the electric heater 609 or the electric chiller 610 can be activated for direct supplementation.

[0031] 5. Piping System Optimization: The inner walls of all airflow conveying pipes are precision-processed to form a low-roughness surface (roughness Ra no greater than 0.8 μm) and coated with a low surface energy anti-adhesion coating (such as fluorocarbon coating, polytetrafluoroethylene coating, or silane nano-coating). This synergistic design effectively reduces fluid resistance, inhibits the adhesion and accumulation of water vapor and pollutants on the pipe walls in the long term, and ensures long-term efficient and stable operation of the system.

[0032] (III) Detailed Implementation Examples of Key Modules 1. Wind energy aggregation and risk mitigation module: such as Figure 1 , Figure 2 , Figure 12As shown, the modular wind energy harvesting device includes a rigid base 102 and an annular inflatable wind collector 101 mounted thereon. A rapid inflation / deflation system includes an air pump 107 and a high-speed exhaust valve 108. A pressure sensor 109 is installed inside the wind collector 101, and an intelligent control center 6 performs intelligent inflation / deflation maintenance and extreme weather avoidance based on the pressure signal. A drain pipe 110 is provided at the top of the rigid base 102, and a drainage channel 111 is formed between adjacent air inlets of the inflatable wind collector 101, leading to the drain pipe 110 for rapid rainwater drainage. To increase the wind energy capture per unit area, at least two inflatable wind collectors can be vertically integrated on the rigid base 102 to form a three-dimensional multi-layered wind energy aggregation device. Figure 12 When initiating venting for disaster avoidance, the intelligent control center 6 prioritizes venting the top-floor wind collector to quickly reduce overall wind resistance and torque, thereby improving disaster avoidance efficiency.

[0033] 2. Cascaded convergence and gas-liquid separation module: such as Figure 1 , Figure 3 , Figure 15 As shown, the cascaded converging module 2 consists of at least two wind energy collection devices 202 and 203 connected in series. The tangential inlets 204 of all devices rotate in the same direction globally, ensuring that multiple airflows are superimposed in the same direction. This module is innovatively constructed to simultaneously achieve swirling centrifugal pressurization and gas-liquid separation. The tangential inlets 204 are designed to tilt downwards towards the main body of the liquid collection chamber 209 (e.g., at an angle β of 10° to 30° with the horizontal plane), optimizing the centrifugal separation and guiding effect of the droplets. The separated liquid is guided to the main body of the liquid collection chamber 209 and discharged through an intelligently controlled linear discharge valve 210 (whose long axis is aligned with the airflow rotation direction to reduce disturbance). This process has minimal interference with the main airflow.

[0034] 3. Pneumatic booster module: such as Figure 1 , Figure 13 , Figure 14 As shown, the pneumatic booster module 3 provides two booster paths: mechanical booster and electric booster. The intelligent control center 6 dynamically selects and adjusts the booster path based on the inlet pressure requirements of the downstream energy separation module 4.

[0035] (1) Mechanical supercharging path: A portion of the airflow is guided to the mechanical drive turbine 301 through the split pipe 303, which drives the coaxial mechanical compressor 302 to supercharge the main airflow through the turbocharger shaft 305. This path has fewer energy conversion links, higher efficiency, and is suitable for stable and continuous high-load conditions.

[0036] (2) Electric booster path: A portion of the airflow is guided to the pneumatic motor 306 through the diversion pipe 303, which drives the booster path generator 307 to generate electricity. The generated electricity supplies the electric compressor 308 to boost the main airflow. Although this path involves multiple energy conversions, it has a fast response speed and high control precision. It mainly serves as a supplement or backup to the mechanical path or is used to handle low-load, highly fluctuating airflow. Through the global energy efficiency optimization algorithm of the intelligent control center, it is ensured that this path contributes a net positive benefit in improving the overall reliability and flexibility of the system and responding to sudden demands.

[0037] The intelligent control center 6 dynamically allocates the airflow ratio for driving the two paths by adjusting the opening of the diversion control valve 304, thereby achieving coordinated pressurization.

[0038] 4. Energy separation module: such as Figure 1 , Figure 4 As shown, the energy separation module 4 employs a multi-inlet vortex tube 401. The tangential air inlets 405, evenly distributed around the circumference of the tube wall, are configured to tilt towards the hot-end outlet 402 (the angle α between their axis and the radial tangent of the vortex tube is 5° to 30°). This design optimizes the vortex morphology and improves energy separation efficiency. By adjusting the hot-end regulating valve 404, the temperature and flow rate ratio of the cold and hot-end airflows can be flexibly controlled.

[0039] 5. Multi-application module: The following combination Figure 1 (System overview diagram) and unit diagrams ( Figures 5 to 10 (etc.) Each application unit is described. The interfaces and connections of each unit within the system are as follows: Figure 1 As shown, the specific internal structure can be found in the respective unit diagrams.

[0040] (1) Power generation unit 51 ( Figure 5 The system includes a Venturi accelerator tube 5101, a turbine 5102, and a generator 5103. The hot-end airflow is accelerated by the Venturi accelerator tube 5101 and then drives the turbine 5102 to rotate and generate electricity.

[0041] (2) Hydrogen production unit 52 ( Figure 6 The system includes an electrolyzer 5201 and a preheating heat exchanger 5202. The hot-end airflow can preheat the electrolytic working fluid, reducing electrolysis energy consumption. The oxygen produced by electrolysis is collected through pipeline 5204 and can be used by the carbon capture unit 55 or the seawater resource recovery unit 54; the produced hydrogen can be synthesized with the captured CO2 in the synthesis reactor 5203 to synthesize green fuel.

[0042] (3) Carbon capture unit 55 ( Figure 7The system includes an adsorption reactor 5501 and a desorption tower 5502. The cold-end gas flow is used to cool the adsorption reactor, improving adsorption efficiency; the hot-end gas flow is used to heat the desorption tower, driving CO2 desorption. Oxygen provided by the hydrogen production unit can be used for oxygen-enriched combustion in the desorption tower, further improving desorption efficiency.

[0043] (4) Seawater desalination unit 53: Multi-stage flash evaporation (MSF) or reverse osmosis (RO) technology can be used. The hot end airflow can be used as the driving heat source for MSF.

[0044] (5) Seawater resource utilization unit 54 ( Figure 9 The desalination unit receives concentrated brine from the seawater desalination unit and uses equipment such as spray drying tower 5401 to produce chemicals such as sea salt, bromine, and magnesium. The water vapor generated during drying is guided back to the condenser 5303 of the seawater desalination unit through steam conveying pipeline 5404 for recovery, thereby improving the overall water recovery rate.

[0045] (6) Air intake water unit 56: includes air contactor 5601 and condensate collector 5602. The cold end airflow of the system flows through air contactor 5601, cooling the humid air therein and causing it to condense into water. The condensate is collected by condensate collector 5602, thereby supplementing the fresh water source in arid areas or specific environments.

[0046] (7) Cooling and heating power generation unit 57 ( Figure 8 The system includes a thermoelectric generator 5701, a hot-end heat exchanger 5702, and a cold-end heat exchanger 5703. The hot-end airflow from the system flows through the hot-end heat exchanger 5702, and the cold-end airflow flows through the cold-end heat exchanger 5703, thereby establishing a stable temperature difference on both sides of the thermoelectric generator 5701, directly generating electricity and realizing the recovery and utilization of low-grade heat energy.

[0047] (8) Compressed air energy storage unit 58 ( Figure 10 Its high-pressure gas storage device 5801 can be connected to the high-pressure gas outlet after the cascaded converging module 2 or the pneumatic booster module 3 to store surplus wind energy. When released, it can generate electricity through the expansion generator set 5802.

[0048] 6. System-level optimized design: The inner walls of all airflow-carrying pipes are precision-processed to form a low-roughness surface (roughness Ra not greater than 0.8 μm) and coated with a low surface energy anti-adhesion coating (such as fluorocarbon coating, polytetrafluoroethylene coating, or silane nano-coating). This synergistic design effectively reduces fluid resistance and inhibits the adhesion and accumulation of water vapor and pollutants on the pipe walls in the long term, ensuring the long-term efficient and stable operation of the system. The system is also equipped with an electric heater 609, an electric chiller 610, and a system-level backup electric compressor 608 for direct supplementation or backup when internal cooling, heating, or pressure energy is insufficient.

[0049] 7. Energy Transmission Insulation and Loss Management Design To minimize energy loss during the delivery of cold and hot airflow generated by the energy separation module 4 to the various multi-application modules 5, and to ensure the high-quality end-use efficiency of cold and hot energy, this invention employs a collaborative design: (1) Pipeline body optimization: As mentioned in point 6 above, all delivery pipelines have extremely low surface roughness and adhesion, which significantly reduces the heat exchange intensity between the airflow and the pipe wall, forming the first barrier to suppress energy loss along the pipeline.

[0050] (2) Active temperature compensation: The intelligent control center 6 monitors the airflow temperature of key nodes in real time (e.g., at the inlet of each application unit). When the temperature of cold or hot airflow deviates from the optimal operating range required by the downstream application unit (such as the adsorption reactor 5501 or desorption tower 5502 of the carbon capture unit 55) due to transmission distance, ambient temperature difference or instantaneous fluctuations, the intelligent control center 6 will dynamically regulate and start the electric heater 609 or electric chiller 610 to accurately reheat or recool the airflow, ensuring the quality and stability of the input energy.

[0051] (3) Optional external insulation: For specific long-distance transportation or high environmental temperature difference application scenarios (such as the island community distributed pipeline network in Example 1 and the large-scale park in Example 2), a conventional insulation layer (such as a polyurethane foam layer or a vacuum insulation layer) can be added to the outside of the pipeline to further reduce energy loss caused by environmental heat exchange. This is a conventional technical means that can be implemented by those skilled in the art according to actual needs.

[0052] The aforementioned collaborative design, especially the low surface energy anti-adhesion coating, is based on the scientific principle that by reducing surface energy, it effectively reduces the adsorption of water molecules or other polar substances on the pipe wall and the release / absorption of latent heat of condensation, thereby suppressing the main energy transfer loss caused by phase change from a mechanistic perspective.

[0053] Through the multi-level collaborative design of "low-loss pipeline foundation, intelligent active compensation, and optional external insulation", the system ensures the stability of energy quality throughout the entire process from energy separation to end-use, providing a reliable guarantee for the overall efficient operation of the system.

[0054] (iv) Implementation examples of dynamic scheduling methods The intelligent control center 6 executes a multi-objective dynamic scheduling strategy, dynamically switching between multiple operating modes based on real-time collected meteorological data, energy demand signals, market price signals, and carbon quota signals.

[0055] 1. Scheduling priority logic: (1) First priority (basic energy guarantee): When the system power supply capacity is insufficient to meet the needs of critical loads (such as control center, water pump), the power priority mode is switched unconditionally.

[0056] (2) Second priority (water resource security): When the freshwater reserves are below the safety threshold, priority shall be given to ensuring the energy supply of the seawater desalination unit 53 and / or the air intake water unit 56.

[0057] (3) Third priority (economic and carbon optimization): Under the above-mentioned guarantee, based on market signals and carbon quota status, optimize and switch to hydrogen production priority, carbon optimization or product priority modes to maximize overall benefits and carbon emission reduction.

[0058] 2. Typical operating mode: (1) Power priority mode: The converged and pressurized airflow is prioritized for driving the power generation unit 51 to generate electricity.
