Description

Technical Field

[0001] This invention relates to the field of energy and power technology, specifically to a power generation device that uses an internal combustion engine to generate steam energy. Background Technology

[0002] Traditional thermal power generation and some heat recovery technologies mainly rely on the direct combustion of fossil fuels or simple recovery of industrial waste heat, resulting in inherent defects such as low energy conversion efficiency, high carbon emissions, and poor system flexibility. Although technologies for generating electricity using waste heat from internal combustion engine exhaust or industrial processes exist, they generally suffer from low thermal energy utilization, system dependence on the main engine's operating conditions, and the inability to form a stable and autonomous power generation cycle. In particular, existing technologies lack a systematic design for the synergistic utilization of the instantaneous heat energy of high-temperature compressed air and the high-pressure phase change characteristics of water, failing to achieve a complete closed loop of "compressed air heat generation - heat energy exchange for steam production - steam power generation - waste pressure circulation" driven only by initial electrical energy without relying on continuous ignition from external fuel. Furthermore, the water-steam circulation system of existing power generation units is often independent of the air compression and heat exchange process, resulting in significant heat loss, unsatisfactory system energy efficiency ratios, and a lack of intelligent full-process coordinated control, making it difficult to achieve efficient, stable, and self-sustaining clean energy power generation.

[0010] Compared with the prior art, the beneficial effects of the present invention are: This invention pioneers an autonomous steam generation mechanism based on "instantaneous high temperature of compressed air and forced heat exchange through a counter-current water circuit," constructing a clean power generation cycle independent of continuous fuel combustion. By activating the air compressor in the compression system, ambient air is compressed to an instantaneous high temperature of 500°C-750°C, serving as the initial heat source. In the heat exchange system, an innovative nested counter-current structure of "integrated high-pressure pipeline assembly" and "built-in water channel capillary tubes" is employed, causing the high-temperature airflow and low-temperature waterflow to flow in opposite directions, forcing efficient heat exchange. The water flow is rapidly heated above its phase change temperature within the capillary tubes, generating high-pressure steam. This system eliminates dependence on continuous combustion of fossil fuels or large, fixed heat sources. It requires only a small amount of initial electrical energy to start the air compressor and can continuously generate driving steam using physical compression and efficient heat exchange principles, achieving a fundamental innovation in energy generation methods.

[0011] This invention achieves tiered energy utilization and near-zero loss closed-loop operation through deep coupling and intelligent management of four systems, greatly improving overall energy efficiency and operational stability. The device deeply integrates four major systems: compression, heat exchange, steam power, and waste pressure and circulation. The steam power system uses the generated steam to drive a turbine to generate electricity. The waste pressure and circulation system ingeniously recovers the waste pressure and heat of the exhaust steam: the waste pressure drives the turbine chamber to pressurize the intake air, improving the compression efficiency of the next cycle; the waste heat is used for system insulation and ultimately condenses the steam into water through a radiator, returning it to the water tank, achieving a zero-emission closed-loop circulation of the working fluid (water). The entire process is monitored and adaptively adjusted in all dimensions by an intelligent management system, ensuring optimal parameters at each stage through pressure regulating valves, temperature sensors, and transmission switches. This design allows the system to achieve a net power output of 70%-80% with only 20%-30% initial energy input, far exceeding the energy utilization efficiency of traditional thermoelectric technology, and possessing the potential for uninterrupted and stable operation 365 days a year. It is a highly competitive new type of independent green power generation solution. Attached Figure Description

[0016] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0017] Please see Figure 1-4 The present invention provides a technical solution: This invention provides a power generation device that utilizes an internal combustion engine to generate steam energy. Its core lies in generating instantaneous high temperatures through physical compression, and then using this high temperature to efficiently exchange heat with water in a counter-current manner to produce steam to drive power generation, ultimately achieving a closed-loop energy cycle and intelligent management. The entire device consists of five major functional modules: a starting compression system, a heat exchange system, a steam power system, a residual pressure and circulation system, and an intelligent management system.

[0018] The starting compression system includes an electric motor 1, an air compressor 2, and an automatic regulating valve 3. During startup, an external power source 42 supplies power to the electric motor 1, which drives the air compressor 2 via a connecting belt 29. The air compressor 2 contains a piston 32 that reciprocates within a cylinder. During the intake stroke, the piston 32 moves downwards, opening the intake valve 30, and drawing in external air through the intake port 4, forming cylinder air 31. During the compression stroke, the piston 32 moves upwards, closing the intake valve 30, and the cylinder air 31 is violently compressed. When the piston 32 approaches top dead center (corresponding to an acute angle region of approximately 30°-40° crankshaft rotation), the cylinder air 31 is compressed to its minimum volume, and its pressure and temperature rise sharply, reaching a pressure of 30-55 MPa and a temperature of 500°C-750°C. At this point, the high-pressure, high-temperature air forces open the automatic regulating valve 3 and is sent to the heat exchange system through the delivery pipe 5. The system's function is to convert electrical energy into the kinetic and thermal energy of high-temperature, high-pressure air, providing an initial high-temperature heat source that does not depend on fuel for subsequent steam generation.

[0019] The heat exchange system mainly includes a low-pressure high-pressure airflow duct 33, an integrated high-pressure duct assembly 28, a built-in water channel capillary tube 9, and a transfer switch 6. High-temperature, high-pressure air from the transfer duct 5 enters the integrated high-pressure duct assembly 28 within the low-pressure high-pressure airflow duct 33 via the transfer switch 6. The integrated high-pressure duct assembly 28 contains a built-in water channel capillary tube 9, forming a main airflow channel 7. The high-temperature air flows from left to right within the main airflow channel 7, releasing heat. Simultaneously, low-temperature water 8 from the residual pressure and circulation system enters the built-in water channel capillary tube 9 through the duct inlet 39 and flows from right to left (counter-current) within the capillary tube. Through this counter-current heat exchange design, the water flow fully absorbs the heat from the high-temperature air, rapidly increasing its temperature to over 200°C-300°C and vaporizing to form high-pressure steam. The high-pressure steam is ejected from the outlet 36 and temporarily stored in the high-pressure steam storage zone 20 on the left. A pressure indicator 10, a pressure regulating valve 11, and a temperature sensor 19 are used to monitor and regulate the pressure and temperature within the duct. The system's function is to achieve efficient countercurrent heat exchange between gas and water working fluids, maximizing the conversion of the instantaneous high temperature of compressed air into the pressure potential energy of water vapor.

[0020] The steam power system consists of an automatic steam output valve 21, a steam turbine 23, and a generator 24. When the steam pressure in the high-pressure steam storage zone 20 reaches a preset value (monitored by pressure gauge 27), the automatic steam output valve 21 opens, and high-pressure steam is injected at high speed through the high-pressure steam delivery pipe 22 onto the blades of the steam turbine 23, driving the turbine to rotate at high speed. The steam turbine 23 drives the generator 24 via a drive belt 34, thereby generating electrical energy. The generated electrical energy is transmitted to the energy storage device 44 for storage or utilization. The function of this system is to convert the pressure energy of high-pressure steam into mechanical energy, and ultimately into usable electrical energy.

[0021] The residual pressure and circulation system aims to recover and utilize the residual pressure and heat after steam has performed work, thereby improving system energy efficiency and circulating the working fluid. It includes a one-way valve 13, a water pump 14, a radiator 16, and a water tank 18. After steam performs work in the steam turbine 23, it becomes exhaust steam but still retains a certain pressure and temperature. The exhaust steam is led back to the pressureless buffer space 40 of the heat exchange system through the residual pressure outlet 25. The residual pressure is used to drive the shaft 45 within the turbine housing 26 to rotate, which in turn drives the intake chamber 46 to rotate. Fresh air is drawn in and pre-compressed through the ventilation duct 47 and air purifier 48, and then sent to the intake port 4 via the intake pipe 49. This increases the intake air density, thereby increasing the initial temperature and pressure of the compressed air in the next cycle, creating a positive gain.

[0022] The waste heat from the exhaust steam, after insulating components such as the integrated high-pressure pipeline assembly 28 within the unpressurized buffer space 40, enters the steam condensation pipeline 38 through the condensate outlet 15 and flows to the radiator 16. In the radiator 16, the exhaust steam is cooled to below 80°C-100°C and recondenses into liquid water. The condensate flows back to the water storage tank 18 under gravity. Driven by the water pump power supply 43, the water pump 14 pumps the water from the water storage tank 18 back into the built-in water circuit capillary tube 9, completing the closed-loop water circulation. The one-way valve 13 prevents backflow. The function of this system is to recover the kinetic energy of the residual pressure and the thermal energy of the waste heat, while simultaneously recovering the working fluid water through condensation, achieving near-zero loss and continuous operation of the system.

[0023] The intelligent management system 41 is electrically connected to the key sensors (such as pressure gauge 27 and temperature sensor 19) and actuators (such as automatic regulating valve 3, delivery switch 6, pressure regulating valve 11, steam output automatic valve 21, and water pump 14) of the four systems mentioned above. It receives system operation data wirelessly or via wired connection and, according to preset programs or remote commands, precisely coordinates and controls the opening and closing of various valves, the start and stop of water pumps, and the power of compressors. For example, it automatically initiates pressure relief when excessive pressure is detected and adjusts the heat exchange flow rate when the water temperature is insufficient, ensuring the safe, stable, and efficient automatic operation of the entire power generation unit. This system is the "brain" of the entire unit, realizing fully automated and intelligent management from startup and power generation to shutdown and maintenance.

[0024] Through the precise collaboration of the above five systems, this invention constructs a technical closed loop with "compression heat generation - countercurrent steam exchange - power generation output - waste energy recovery" as its core, realizing the continuous production of a large amount of clean electricity with only a small amount of initial electrical energy consumption, and has significant advantages of high efficiency, greenness, autonomy and intelligence.
