Description

Technical Field

[0001] This invention relates to the field of energy conversion technology, and in particular to a space radiation energy harvesting and conversion system. Background Technology

[0002] Currently, human society's demand for energy is enormous and ever-increasing. Traditionally, this energy has primarily relied on the chemical conversion of fossil fuels such as coal, oil, and natural gas. However, this energy model faces multiple challenges: First, the extraction, transportation, and conversion of fossil fuels are complex processes requiring massive infrastructure and equipment, resulting in high economic costs. Second, these energy sources are not inexhaustible; their reserves are finite and unevenly distributed, and they may face the risk of depletion in the future. Most importantly, the conversion process of fossil fuels generates large amounts of waste gas, causing severe atmospheric pollution and exacerbating global warming and environmental degradation.

[0003] To address these challenges, finding a sustainable, environmentally friendly, and cost-effective alternative energy source has become a global consensus. This invention arose in this context, aiming to collect and utilize radiant energy from Earth's surface through an innovative method. This invention will fundamentally solve humanity's energy problems and produce electricity at extremely low cost, thus providing society with a clean, unlimited, and economical energy source. Summary of the Invention

[0004] This invention proposes a device that can extract all space radiation energy from the Earth's surface. This device can collect and convert energy for use, thereby solving the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a space radiation energy harvesting and conversion system, comprising a motor, a main shaft, a steam turbine, an expander, and a synchronous generator.

[0006] The electric motor, steam turbine, expander, and synchronous generator are sequentially mounted on the main shaft. Clutch 1 and Clutch 2 are respectively mounted on the main shaft to the right of the electric motor and the left of the steam turbine. Gearbox 1, Gearbox 2, and Gearbox 3 are sequentially mounted on the main shaft between Clutch 1 and Clutch 2. Gearbox 1, Gearbox 2, and Gearbox 3 control air compressor 1, air compressor 2, and air compressor 3, respectively.

[0007] The air compressor is provided with an air inlet. The air compressor is connected to the heat release pipe in the heat exchanger through a high-pressure air pipe. The heat release pipe at the bottom of the heat exchanger is connected to the energy storage tank through the high-pressure air pipe. The energy storage tank is connected to the expander. The expander is provided with a cold air outlet.

[0008] The second air compressor is connected to the heat exchanger and the heat release pipe in the steam generator through pipes respectively. The bottom end of the heat release pipe in the steam generator is connected to the energy storage tank through a pipe. A check valve is installed on the pipe connecting the heat release pipe and the energy storage tank. The steam generator is connected to the steam turbine and the third air compressor through pipes respectively.

[0009] The air compressor is connected to the space energy absorber via a pipe. The space energy absorber is connected to the condenser via a pipe. An expansion valve is installed on the pipe between the condenser and the space energy absorber. The condenser is connected to the steam turbine, heat exchanger, and steam generator via pipes. A reflux pump is installed on the pipe between the condenser and the steam generator. The condenser is equipped with an air inlet.

[0010] Furthermore, the system is started by an electric motor, which rotates the main shaft and drives the air compressor to work, compressing air from the air inlet into high-temperature and high-pressure gas and delivering it to the energy storage tank.

[0011] Furthermore, when the pressure in the energy storage tank reaches a preset value, the system starts the expander to output energy and controls the rotation speed to connect the synchronous generator to the power grid.

[0012] Furthermore, the air compressor draws in air from the air inlet, which enters the condenser to absorb condensation heat, and then is sent through a conduit to the heat exchanger to absorb heat energy from the heat release tube.

[0013] Furthermore, the high-temperature air is compressed by an air compressor to achieve an exhaust temperature of over 600 degrees Celsius, and then transported to a steam generator to convert the liquid into a high-temperature, high-pressure gas.

[0014] Furthermore, the high-temperature and high-pressure gas generated by the steam generator drives the steam turbine to work, converting thermal energy into mechanical energy, which is then converted into electrical energy output by the synchronous generator.

[0015] Furthermore, the low-temperature, low-pressure gas discharged from the turbine enters the condenser and is condensed into liquid, which is then pumped back to the steam generator for recycling.

[0016] Furthermore, the energy absorber expands by depressurizing through an expansion valve, causing its temperature to drop to around -20 degrees Celsius, thereby absorbing heat energy from the external space of the system.

[0017] Compared with existing technologies, the advantages and positive effects of this invention are as follows: This space radiation energy harvesting and conversion system, based on various gas characteristics, through processes such as gas compression, heat exchange, and expansion, forces the gas entering the system to release energy. Gas entering the system at approximately 20 degrees Celsius (normal room temperature) undergoes a series of treatments to control the exhaust temperature at approximately -30 degrees Celsius, thus significantly reducing the gas's enthalpy and releasing a large amount of heat to the system. The energy absorber in the system, due to its temperature being much lower than normal, can absorb a large amount of energy from outer space to supply the system. Therefore, the total energy absorbed by the system from the air minus the total system losses equals the power output of the system. It has the following advantages:

[0018] 1. Unlimited energy source: This invention utilizes the radiation energy in the air and water, which is an inexhaustible energy source.

[0019] 2. Extremely low cost: This invention can reduce the cost of generating one kilowatt-hour of electricity to one cent.

[0020] 3. Environmentally friendly: The system does not rely on fossil fuels, thus avoiding pollution of nature by exhaust emissions.

[0021] 4. High-efficiency energy conversion: The system utilizes the compression, heat exchange and expansion processes of gas to force the gas entering the system to release a large amount of energy, thereby achieving high-efficiency energy conversion.

[0022] 5. Energy absorption: The energy absorber in the system utilizes the low-temperature characteristics to absorb a large amount of heat energy from the external space, providing additional energy for the system.

[0023] 6. Automated control: The system is equipped with an automatic control system that can automatically adjust the power and flow of each component to keep the system in a reasonable dynamic balance. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1

[0029] like Figure 1 As shown, this invention provides a space radiation energy harvesting and conversion system. The motor 1 starts, the clutch 2 engages, causing the main shaft 6 to rotate. The gearbox 3 is activated, driving the air compressor 11 to operate, drawing air in through the air inlet 22 and compressing it into high-temperature, high-pressure gas. This gas is then transported to the energy storage tank 20 through the high-pressure air pipe 14.

[0030] When the pressure inside the energy storage tank 20 reaches the set value, the expander 9 is activated, and it outputs energy. The speed of the expander 9 is controlled to drive the synchronous generator 10 and connect it to the power grid. After the synchronous generator 10 is connected to the grid, clutch 72 is engaged, clutch 12 is disengaged, and the motor 1 stops running. Thus, the driving force for all air compressors is provided by the turbine 8, expander 9, and synchronous generator 10. Because the air in the energy storage tank 20 releases a large amount of heat and is a high-pressure, low-temperature gas, the exhaust temperature of the expander 9 after expansion and work is very low. Generally, the system controls it at -30 degrees Celsius. Experiments show that the inlet pressure of the expander 9 is 2 MPa, and the inlet temperature is 180 degrees Celsius with steam and 120 degrees Celsius with refrigerant, resulting in the highest system efficiency. The discharged cold air can be used in refrigeration facilities or input into the condenser 19 to reduce the condensing pressure, increase the output power of the turbine 8, and adjust the inlet flow rate of the expander 9. This stabilizes the air pressure inside the energy storage tank 20 at the set pressure.

[0031] Engage gearbox 3 (4) to start air compressor 2 (12). Air enters condenser 19 through inlet 2 (23), absorbing heat released during condensation and raising its temperature. This air is then sent to heat exchanger 15 via a duct. Due to the extremely high temperature of heat exchanger 15's heat pipes 16, the air absorbs a significant amount of heat. This high-temperature air is then transported to air compressor 2 (12) via a duct. The intake temperature of air compressor 2 (12) can reach over 100 degrees Celsius, significantly increasing its outlet temperature. Given that the exhaust pressure of a typical air compressor is around 2 MPa, this allows the outlet temperature to reach over 600 degrees Celsius. This high-temperature, high-pressure gas is then transported to steam generator 17 via high-pressure duct 14. High-pressure duct 14 releases a large amount of heat into the liquid (water or refrigerant) in steam generator 17, transforming it into a high-temperature, high-pressure gas. After the air in the steam generator 17 releases heat, the temperature of the high-pressure air decreases, but the air pressure does not decrease. This high-pressure gas is transported from the heat release pipe 16 in the steam generator 17 to the energy storage tank 20 through the high-pressure gas guide pipe 14 for use by the expander 9.

[0032] Because the liquid in steam generator 17 absorbs a large amount of heat energy and becomes high-temperature, high-pressure gas, this high-pressure gas is transported to the inlet of steam turbine 8 through high-pressure gas pipe 14, starting steam turbine 8 and enabling it to operate. Adjusting the inlet flow rate of steam turbine 8 controls the temperature and pressure of the steam in steam generator 17, keeping the entire system in a dynamic equilibrium state. Steam turbine 8 and expander 9 simultaneously convert the heat energy of the gas into mechanical energy, which is input into synchronous generator 10, and then converted into electrical energy for output. The low-temperature, low-pressure gas discharged from steam turbine 8 is sent to condenser 19 through a conduit, causing the gas to release heat and become liquid. This condensed liquid is then pumped back into steam generator 17 by return pump 25 for recycling.

[0033] If the liquid in the steam generator 17 is a refrigerant, a space energy absorber 18 can be added to the system, and an expansion valve 24 can be added to the outlet pipe of the condenser 19. Since the refrigerant will atomize due to pressure reduction and expansion, it will enter the space energy absorber 18 pipe and evaporate, which can lower the temperature of the space energy absorber 18 to about -20 degrees Celsius. In this way, the space energy absorber 18 will absorb a large amount of heat energy from the space outside the system (air or water), turning the low temperature gas into a normal temperature gas, which is then compressed into a high temperature and high pressure gas by the air compressor 13 and sent into the steam generator 17 through the gas pipe for use by the steam turbine 8.

[0034] The entire system can sense the pressure, temperature, and flow rate of the gas within the system through sensors and transmit this information to the automatic control system, thereby automatically controlling the operation of each component and keeping the system in a dynamic equilibrium state. The total output power of the system is equal to the total energy absorbed from the air minus the total losses of the system (including mechanical losses, thermal radiation, and efficiency losses).

[0035] Example 2

[0036] like Figure 1 As shown, the present invention provides a space radiation energy harvesting and conversion system.

[0037] The implementation steps and data of the system are described below: The parameters of each device are as follows:

[0038] Motor 1 is an asynchronous motor with a power of 22 kilowatts and a speed of 1440 rpm.

[0039] Air compressor 11, with a power of 7.5 kW and a pressure difference of 3 MPa screw type (12), with a power of 12.5 kW and a pressure difference of 3 MPa screw type.

[0040] The steam turbine is a condensing steam turbine with a power of 22 kilowatts and an inlet pressure of 2.5 MPa.

[0041] Expander 9, a turbine with a power output of 22 kW and an inlet pressure of 2.5 MPa.

[0042] Synchronous generator 10, a 55 kW three-phase motor.

[0043] High-pressure air delivery tube 14, all of the tubes have an outward pressure exceeding 3MPa.

[0044] Air compressor 313, power 12.5 kW, pressure difference 3 MPa screw type.

[0045] The refrigerant used in the steam generator 17, which is subjected to external pressure of over 4MPa at a high temperature of 400 degrees Celsius, is dichloromethane (R22).

[0046] The energy storage tank is 20, with a volume of 1 cubic meter, and is subjected to external pressure of over 4 MPa.

[0047] The specific operating procedure is as follows: Start motor 1, engage clutch 2, and the main shaft 6 begins to rotate. Engage gearbox 3 and start air compressor 11 at the lowest speed. As air compressor 11 begins to operate, air enters through inlet 22 and is compressed. The inlet temperature is measured to be 25 degrees Celsius. The pressurized air is then transported to energy storage tank 20 through the air pipe, causing the pressure in energy storage tank 20 to gradually increase. Observe the pressure and temperature gauges on energy storage tank 20. After 15 minutes of operation, the pressure gauge reading reaches 2 MPa, and the temperature gauge reading is 180 degrees Celsius. At this point, the outlet temperature of air compressor 11 is measured to be 380 degrees Celsius, and the pressure is the same as that in energy storage tank 20. Immediately start expander 9 to rotate the main shaft 6. This will also rotate the turbine 8 and synchronous generator 10. Gradually increase the opening of the expander 9's inlet valve, increasing the rotation speed of the main shaft 6 and the frequency of the synchronous generator 10. When grid connection conditions are met, connect the synchronous generator 10 to the power grid. At this time, the synchronous generator 10 can either absorb electrical energy from the grid to become a motor, or transmit electrical energy to the grid to become a generator.

[0048] Adjusting the transmission 3, the air compressor 11 was brought to its rated power. The active power reading on the motor's power meter was observed to be 7.2 kW. At this point, the pressure in the energy storage tank 20 increased. Immediately, the intake valve of the expander 9 was adjusted to increase the intake air volume, which also increased the output power of the expander 9. After 5 minutes of adjustment, when the pressure in the energy storage tank 20 stabilized, the synchronous generator 10 was observed to output 4.9 kW to the grid. 7.2 kW minus 4.9 kW equals 2.3 kW, indicating a system efficiency of 70%. The intake air temperature of the expander 9 was measured at 180 degrees Celsius, the intake pressure at 2 MPa, and the exhaust temperature at -9 degrees Celsius. The intake air temperature was still slowly rising.

[0049] First, observe the refrigerant level (R22 is used here) in the steam generator 17, and the pressure gauge reading is 0.8 MPa, and the temperature gauge reading is 25 degrees Celsius. These are normal design values. Then, engage gearbox 4 to start compressor 12 at minimum speed. Air will enter condenser 19 through inlet 23 and then be sent to heat exchanger 15 through the air pipe. Since turbine 8 has not yet started, the air temperature of 25 degrees Celsius and the pressure of 0.1 MPa between inlet 23 and heat exchanger 15 are equal. After energy exchange in heat exchanger 15, the air temperature at inlet 23 of air compressor 12 is 98 degrees Celsius, and the air pressure remains unchanged. After being compressed by air compressor 12, the pressure at the nozzle of air compressor 12 increases to 2 MPa, and the temperature reaches 518 degrees Celsius. The high-temperature, high-pressure air enters the steam generator 17 and rapidly transfers heat to the dichloromethane (R22) liquid within it. The R22, having absorbed heat, quickly heats up and boils. The air, releasing heat, is then piped through check valve 21 into the energy storage tank 20. The air temperature decreases to 112 degrees Celsius while the pressure remains constant at 2 MPa as it passes through check valve 21. Simultaneously, the air supplied from the heat exchanger 15 releases heat, resulting in a pressure of 2 MPa and a temperature decrease to 136 degrees Celsius at the inlet of the energy storage tank 20. At this point, the pressure gauge reading in the energy storage tank 20 increases. Immediately increasing the airflow into the turbine 8 stabilizes the pressure in the energy storage tank 20 at approximately 2 MPa, and when the power of air compressor 12 reaches its rated value, the output power of the synchronous generator 10 is observed to be 14.2 kW. The total input power of air compressors 11 and 12 is 19.4 kW. The system efficiency at this point is 73%. It takes 5.2 kilowatts of power drawn from the grid to ensure stable operation.

[0050] First, engage clutch 2 (7), then disengage clutch 1 (2), stopping motor 1. In this way, the power for air compressor 2 (12) is supplied by expander 9 and synchronous generator 10. The power display of synchronous generator 10 shows a negative value of -5.2 kW, indicating that synchronous generator 10 has switched to motor operation.

[0051] Observe the temperature and pressure gauges on the steam generator 17. Due to the large amount of heat absorbed by the liquid R22, the temperature and pressure will rise accordingly. When the pressure rises to 2.5 MPa, the temperature rises to 82 degrees Celsius. Open the inlet valve of the steam turbine 8 and slowly increase the inlet flow rate of the steam turbine 8 to increase the output power of the steam turbine 8. Adjusting the inlet flow rate of the steam turbine 8 can control the pressure and temperature of the gas in the steam generator 17.

[0052] The condenser 19 operates at a pressure of 0.8 MPa and a temperature of 40 degrees Celsius. The heat released during condensation is absorbed by the air and carried into the heat exchanger 15. The reflux pump 25 is activated to pump the condensed R22 liquid into the steam generator 17. At this point, the synchronous generator 10 delivers 12.5 kW of active power to the grid, and the turbine performs 17.7 kW of work.

[0053] Open expansion valve 24, engage transmission 3 5, and start air compressor 3 13. After 3 minutes, the temperature at the inlet of the air duct of space energy absorber 18 is measured to be -28 degrees Celsius. Because this temperature is below ambient 55 degrees Celsius, space energy absorber 18 will absorb a large amount of energy from the space outside the system. The temperature at the air inlet of air compressor 3 13 will rise to 23 degrees Celsius. The intake valve of turbine 8 will be widened again to increase the output power of turbine 8. Once the entire system reaches dynamic stability, the active power delivered to the grid by synchronous generator 10 is 38 kilowatts. The function of generating electricity by absorbing energy from the air has been successfully achieved. If water is used as the medium in steam generator 17, space energy absorber 18 cannot be used, and the pressure values ​​of all equipment in the system will increase.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
