Description

Technical Field

[0001] The present invention relates to the technical field of energy conversion, and in particular to an electric energy conversion system based on solar radiation energy and natural fluid thermal energy. Background Art

[0002] As a clean, renewable energy source, solar energy has great potential to meet the world's growing electricity demand. With the reduction of dependence on traditional fossil fuels and the increase of environmental awareness, research and development of efficient solar energy conversion technology is essential to achieve sustainable development.

[0003] In the prior art, solar energy is usually converted into electrical energy in the form of photovoltaic panels, which has certain limitations. Specifically, photovoltaic panels are usually composed of a number of silicon wafers, and the manufacturing process of silicon wafers is complex and requires high precision, which makes the manufacturing cost high, and the photovoltaic panels occupy a large area when used.

[0004] In summary, how to solve the problems of high cost and large area occupied in the form of electricity conversion using photovoltaic panels in the existing technology has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an electricity conversion system based on solar radiation energy and natural fluid thermal energy. Summary of the invention

[0005] To solve the above problems, the present invention provides an electric energy conversion system based on solar radiation energy and natural fluid thermal energy. Through the integration of multiple components, the same energy output can be achieved in a smaller space, reducing installation costs and space requirements. Buoyancy is used to make the semi-enclosed box move up and down, thereby providing kinetic energy for the moving parts, further driving the generator and gas compressor to work, achieving effective multi-level energy transmission and utilization, thereby reducing costs.

[0006] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: an electric energy conversion system based on solar radiation energy and natural fluid thermal energy, comprising a heat transfer working medium A and a heat transfer working medium B and the following modules and components:

[0007] The thermal energy collection module is used to receive the thermal energy generated by sunlight and transmit the thermal energy to the thermal energy storage module.

[0008] The thermal energy storage module is used to store the thermal energy conducted from the thermal energy collection module, and utilize the thermal energy to heat the heat transfer working medium A; and transmit the heated heat transfer working medium A to the bubble buoyancy turbine module.

[0009] The bubble buoyancy turbine module is used to receive the heat transfer working medium A after the heating treatment, and utilize the vaporization and liquefaction process of the heat transfer working medium A to convert it into kinetic energy to drive the generator and the gas compressor to work.

[0010] The heat exchange tube is used to connect the thermal energy storage module and the bubble buoyancy turbine module to transfer heat.

[0011] The generator is used to utilize the bubble buoyancy turbine module to drive the generator to rotate, and convert the mechanical energy of the generator rotation into electrical energy.

[0012] The gas compressor is used to utilize the bubble buoyancy turbine module to drive the gas compressor to start and compress the heat transfer working medium B.

[0013] The internal evaporator is located inside the bubble buoyancy turbine module and is used to absorb the heat of the gas and liquefy the heat transfer working medium A.

[0014] The external evaporator is located outside the bubble buoyancy turbine module and is used to absorb fluid heat from the natural environment.

[0015] The condenser is located inside the thermal energy storage module and is used to cool the heat transfer working medium B after being heated by the gas compressor and release heat.

[0016] The expansion valve is connected to the inner evaporator, the outer evaporator and the condenser respectively, and is used to adjust the state of the heat transfer working medium B.

[0017] Intelligent control module, used to monitor and control the operation of each module and component in the system.

[0018] Furthermore, the thermal energy storage module is composed of a sealed first container and an aqueous solution in the first container.

[0019] Furthermore, the bubble buoyancy turbine module is composed of a sealed second container, a plurality of semi-enclosed boxes, a plurality of rotating shafts and a plurality of chains; the heat transfer working medium A is stored in the sealed second container, and the chain is used to connect the semi-enclosed boxes and the rotating shafts.

[0020] Further, the working steps of the thermal energy storage module are as follows:

[0021] S101, transferring the thermal energy collected by the thermal energy collection module to the thermal energy storage module to heat the aqueous solution in the first container.

[0022] S102. When the temperature of the aqueous solution rises, the heat exchange tube transfers the heat to the heat transfer working medium A in the bubble buoyancy turbine module.

[0023] S103. When the surface temperature T1 of the heat exchange tube exceeds the boiling point T2 of the heat transfer working medium A, the heat transfer working medium A on the surface of the heat exchange tube vaporizes and converts into gas.

[0024] S104, transmitting the converted gas to the bubble buoyancy turbine module.

[0025] Further, in S103, the boiling point T2 of the heat transfer working medium A is between 40°C and 80°C.

[0026] Further, the working steps of the bubble buoyancy turbine module are as follows:

[0027] S201. The converted gas is introduced into a plurality of semi-enclosed boxes immersed in the heat transfer working medium A and filled with the semi-enclosed boxes. After the semi-enclosed boxes are filled with gas, they move upward under the action of buoyancy, and the gas and heat transfer working medium A inside the semi-enclosed boxes are discharged when they move to the highest point.

[0028] S202. After the gas is discharged, several semi-enclosed boxes move downward under the action of gravity and sink into the heat transfer working medium A. During the sinking process, the semi-enclosed boxes are filled with the heat transfer working medium A again, and then descend to the lowest point.

[0029] S203. When descending to the lowest point, the semi-enclosed box is filled with the converted gas again and continues to float up. During the process of the semi-enclosed box continuously floating up and down, the rotating shaft is driven to rotate through the chain; the rotating shaft rotates to drive the generator and the gas compressor to work.

[0030] Further, the working steps of the gas compressor are as follows:

[0031] S301. Add heat transfer working medium B to the gas compressor. The gas compressor compresses and heats the heat transfer working medium B to raise its temperature to temperature T3. Temperature T3 is higher than the boiling point T2.

[0032] S302, the heated heat transfer working medium B flows through the condenser, and the condenser releases the heat and conducts it to the aqueous solution of the thermal energy storage module, and the temperature drops to T4.

[0033] S303, the cooled heat transfer working medium B is transmitted to the expansion valve, and the expansion valve converts the heat transfer working medium B into a low-temperature and low-pressure gas-liquid mixture, whose temperature is reduced to T5, and the T5 temperature is lower than 0°C.

[0034] S304, the heat transfer working medium B after the temperature is reduced flows into the inner evaporator and the outer evaporator respectively; the heat transfer working medium B in the inner evaporator and the outer evaporator absorbs the heat in the environment to vaporize, and after the vaporization reaction, the temperature rises to T6 and flows back to the gas compressor.

[0035] S305. At the same time, the internal evaporator reduces the temperature of the heat transfer working medium A gas and liquefies it and flows back into the bubble buoyancy turbine module, and the cycle is repeated continuously under the drive of the rotating shaft.

[0036] Furthermore, the cooling power of the inner evaporator is greater than the heating power of the heat exchange tube in the bubble buoyancy turbine module.

[0037] Furthermore, the intelligent control module includes the following units:

[0038] Sensing units are used to monitor the temperature, pressure and flow of each module and component in the system.

[0039] The control unit is used to adjust the fluid flow, the pressure of the gas compressor and the opening of the expansion valve according to the data fed back by the sensor unit.

[0040] The protection unit is used to set the monitoring threshold of the sensor unit, cut off the power supply and send out an alarm signal under abnormal circumstances.

[0041] The remote control unit is used to provide a remote control interface.

[0042] Furthermore, the intelligent control module also includes an energy management unit, which is used to adjust the angle of the thermal energy collection module, track and concentrate sunlight; and store the electrical energy generated by the generator.

[0043] The above scheme has the following beneficial effects:

[0044] 1. The present invention effectively receives the heat energy generated by sunlight through the heat energy collection module, and stores it in the heat energy storage module to heat the aqueous solution. The heat exchange tube acts as a medium for heat transfer, vaporizes the aqueous solution under appropriate temperature conditions, and efficiently transfers the vaporized gas to the bubble buoyancy turbine module. The gas forms a continuous energy conversion process through the up and down reciprocating motion of the semi-enclosed box. This process not only converts thermal energy into mechanical energy, but also drives the rotating shaft to rotate through the chain, further driving the generator and gas compressor to work, realizing the effective transmission and utilization of multi-level energy, thereby reducing costs.

[0045] Using solar energy as the main energy source reduces dependence on fossil fuels and helps reduce greenhouse gas emissions and other pollutants.

[0046] 2. The present invention uses multi-stage heat exchange between heat exchange tubes, condensers, internal evaporators and external evaporators, so that the system can more efficiently utilize heat from different sources, thereby improving the overall thermal efficiency. Not only does it utilize the heat energy of solar radiation, but it also combines the heat energy of low-temperature fluids in nature to further improve the overall energy utilization rate. The entire system forms a self-sustaining energy conversion cycle, reducing the demand for external energy, improving energy conversion efficiency, and further reducing costs.

[0047] The internal evaporator not only helps to reduce the temperature of the heat transfer working medium A gas and liquefy it and flow back to the bubble buoyancy turbine module, but also effectively manages the heat distribution in the system by having a cooling power greater than the heating power of the heat exchange tube in the bubble buoyancy turbine module. The expansion valve accurately adjusts the state of the heat transfer working medium B to ensure that the internal pressure and temperature of the system remain within a safe range, thereby reducing the system failure rate caused by overpressure or low temperature.

[0048] 3. The bubble buoyancy turbine module of the present invention utilizes buoyancy to move the semi-enclosed box up and down, thereby providing kinetic energy for the moving parts and converting the kinetic energy into electrical energy, which in turn can power the electrical components of the device. This natural physical phenomenon reduces the demand for additional power and ensures the stability and reliability of the system.

[0049] 4. The present invention enables the system to self-adapt under various environments by introducing an intelligent control module to ensure long-term stable operation. The existence of the protection unit can effectively prevent failures or damage caused by external conditions; through the coordinated work of the sensor unit and the control unit, the refined management and real-time regulation of each part of the system can be achieved, which can effectively reduce energy loss and improve the overall energy conversion efficiency.

[0050] The remote control unit provides a flexible operation mode, allowing users to monitor and manage the operating status of the system anytime and anywhere, thus facilitating daily maintenance and troubleshooting. The addition of the energy management unit not only improves the energy absorption capacity of the system, but also makes it suitable for more types of environments. Through the integration of multiple components, the same energy output can be achieved in a smaller space, reducing installation costs and space requirements.

[0060] The specific functions of each module and component are as follows:

[0061] The thermal energy collection module is used to receive the thermal energy generated by sunlight and transfer the thermal energy to the thermal energy storage module; in this embodiment, the thermal energy collection module adopts high-efficiency heat collection materials and technologies, such as focusing mirror reflection, multi-layer insulation structure, etc., to enhance the absorption efficiency of sunlight and reduce heat loss.

[0062] The thermal energy storage module is composed of a sealed first container and an aqueous solution in the first container. In this embodiment, the aqueous solution is a propylene glycol aqueous solution 12, which is mainly used to store the thermal energy conducted from the thermal energy collection module, and use the thermal energy to heat the heat transfer working medium A; and transmit the heated heat transfer working medium A to the bubble buoyancy turbine module.

[0063] Specifically, the working steps of the thermal energy storage module are as follows:

[0064] S101, transferring the thermal energy collected by the thermal energy collection module to the thermal energy storage module to heat the aqueous solution in the first container.

[0065] S102, when the temperature of the aqueous solution rises, the heat exchange tube 4 transfers the heat to the heat transfer working medium A in the bubble buoyancy turbine module.

[0066] S103. When the surface temperature T1 of the heat exchange tube 4 exceeds the boiling point T2 of the heat transfer working medium A, the heat transfer working medium A on the surface of the heat exchange tube 4 vaporizes and converts into gas. In this embodiment, the boiling point T2 is 75°C.

[0067] S104, transmitting the converted gas to the bubble buoyancy turbine module.

[0068] The bubble buoyancy turbine module is composed of a sealed second container, a plurality of semi-enclosed boxes, a plurality of rotating shafts and a plurality of chains; the heat transfer working medium A is stored in the sealed second container, and the chain is used to connect the semi-enclosed box and the rotating shaft. The bubble buoyancy turbine module is used to receive the heat transfer working medium A after heating treatment, and utilizes the vaporization and liquefaction process of the heat transfer working medium A to convert it into kinetic energy, thereby driving the generator 5 and the gas compressor 6 to work.

[0069] The heat exchange tube 4 is used to connect the thermal energy storage module and the bubble buoyancy turbine module to transfer heat; it ensures that heat can be accurately transferred from the thermal energy storage module to the heat transfer working medium A in the bubble buoyancy turbine module, providing necessary heat source support for subsequent energy conversion.

[0070] Specifically, the working steps of the bubble buoyancy turbine module are as follows:

[0071] S201. The converted gas is introduced into a plurality of semi-enclosed boxes immersed in the heat transfer working medium A and filled with the semi-enclosed boxes. After the semi-enclosed boxes are filled with gas, they move upward under the action of buoyancy, and the gas and heat transfer working medium A inside the semi-enclosed boxes are discharged when they move to the highest point.

[0072] S202. After the gas is discharged, several semi-enclosed boxes move downward under the action of gravity and sink into the heat transfer working medium A. During the sinking process, the semi-enclosed boxes are filled with the heat transfer working medium A again, and then descend to the lowest point.

[0073] S203, when descending to the lowest point, the semi-enclosed box is filled with the converted gas again and continues to float up. During the process of continuous floating and descending of the semi-enclosed box, the rotating shaft is driven to rotate by the chain; the rotating shaft rotates to drive the generator 5 and the gas compressor 6 to work.

[0074] The generator 5 is used to drive the generator 5 to rotate using the bubble buoyancy turbine module, and convert the mechanical energy of the generator 5 into electrical energy; in this example, the generator 5 adopts conventional technical means, and its principle is not described in detail in this embodiment.

[0075] The gas compressor 6 is used to start the gas compressor 6 by utilizing the bubble buoyancy turbine module to compress the heat transfer working medium B.

[0076] The internal evaporator 7 is located inside the bubble buoyancy turbine module, and is used to absorb gas heat and liquefy the heat transfer working medium A. The cooling power of the internal evaporator 7 is greater than the heating power of the heat exchange tube 4 in the bubble buoyancy turbine module, and effectively manages the heat distribution in the system.

[0077] The external evaporator 7 is located outside the bubble buoyancy turbine module and is used to absorb fluid heat in the natural environment to enhance the energy utilization efficiency of the system.

[0078] The condenser 9 is located inside the thermal energy storage module and is used to cool the heat transfer working medium B after being heated by the gas compressor 6 and release heat.

[0079] The expansion valve 10 is connected to the inner evaporator 7 , the outer evaporator 7 and the condenser 9 respectively, and is used to adjust the state of the heat transfer working medium B to ensure that it is under appropriate low temperature and low pressure conditions when entering the inner evaporator 7 and the outer evaporator 7 .

[0080] The intelligent control module is used to monitor and control the operation of each module and component in the system.

[0081] Specifically, the working steps of the gas compressor 6 are as follows:

[0082] S301. Add heat transfer working medium B to the gas compressor 6. The gas compressor 6 compresses and heats the heat transfer working medium B to raise its temperature to a temperature T3. The temperature T3 is higher than the boiling point T2.

[0083] S302, the heated heat transfer working medium B flows through the condenser 9, and the condenser 9 releases the heat and conducts it to the aqueous solution of the thermal energy storage module, and the temperature is reduced to T4.

[0084] S303, the cooled heat transfer working medium B is transmitted to the expansion valve 10, and the expansion valve 10 converts the heat transfer working medium B into a low-temperature and low-pressure gas-liquid mixture, whose temperature is reduced to T5, and the T5 temperature is lower than 0°C.

[0085] S304, the heat transfer working medium B after the temperature is reduced flows into the inner evaporator 7 and the outer evaporator 7 respectively; the heat transfer working medium B in the inner evaporator 7 and the outer evaporator 7 absorbs the heat in the environment and vaporizes, and after the vaporization reaction, the temperature rises to T6 and flows back to the gas compressor 6.

[0086] S305. At the same time, the internal evaporator 7 reduces the temperature of the heat transfer working medium A gas and liquefies it and flows back into the bubble buoyancy turbine module, and the cycle is repeated continuously under the drive of the rotating shaft.

[0087] In the prior art, when converting solar energy into electrical energy, photovoltaic panels are usually used. They are mainly made of silicon wafers, and the production cost of silicon wafers is relatively high. When solar panels are used, they also occupy a large area. In this embodiment, the thermal energy generated by sunlight is effectively received by the thermal energy collection module and stored in the thermal energy storage module to heat the aqueous solution. The heat exchange tube 4 serves as a medium for heat transfer. The aqueous solution is vaporized under appropriate temperature conditions, and the vaporized gas is efficiently transferred to the bubble buoyancy turbine module. The gas forms a continuous energy conversion process through the up and down reciprocating motion of the semi-enclosed box. This process not only converts thermal energy into mechanical energy, but also drives the rotating shaft to rotate through the chain, further driving the generator 5 and the gas compressor 6 to work, thereby realizing the effective transmission and utilization of multi-stage energy.

[0088] In this embodiment, through the multi-stage heat exchange between the heat exchange tube 4, the condenser 9, the inner evaporator 7 and the outer evaporator 7, the system can more efficiently utilize heat from different sources, thereby improving the overall thermal efficiency. The inner evaporator 7 not only helps to reduce the temperature of the heat transfer working medium A gas and liquefy it and flow it back into the bubble buoyancy turbine module, but also effectively manages the heat distribution in the system by having its cooling power greater than the heating power of the heat exchange tube 4 in the bubble buoyancy turbine module, and accurately adjusts the state of the heat transfer working medium B through the expansion valve 10, ensuring that the internal pressure and temperature of the system remain within a safe range, thereby reducing the system failure rate caused by overpressure or low temperature.

[0089] It not only utilizes the heat energy of solar radiation, but also combines the heat energy of low-temperature fluids in nature, further improving the overall energy utilization rate. The entire system forms a self-sustaining energy conversion cycle, reducing the demand for external energy, improving energy conversion efficiency, and further reducing costs. Through the integration of multiple components, the same energy output can be achieved in a smaller space, reducing installation costs and space requirements.

[0090] Embodiment 2:

[0091] As attached Figure 2 As shown, the difference from the above embodiment is that the intelligent control module includes the following units:

[0092] The sensing unit is used to monitor the temperature, pressure and flow of each module and component in the system. In this embodiment, the sensing unit mainly includes a pressure sensor, a temperature sensor and a flow sensor.

[0093] The control unit is used to adjust the fluid flow, the pressure of the gas compressor 6 and the opening of the expansion valve 10 according to the data fed back by the sensor unit. In this embodiment, the control unit mainly includes a controller and an actuator.

[0094] The protection unit is used to set the monitoring threshold of the sensor unit, cut off the power supply and send out an alarm signal under abnormal circumstances. In this embodiment, the alarm signal is sent out using a buzzer.

[0095] The remote control unit is used to provide a remote control interface; it allows users to view system performance in real time via the Internet or mobile applications and make necessary operational settings, such as starting / stopping certain components or adjusting operating parameters.

[0096] The energy management unit is used to adjust the angle of the thermal energy collection module to track and concentrate sunlight; and to store the electrical energy generated by the generator 5. In this embodiment, batteries or supercapacitors can be used to store the converted electrical energy.

[0097] This embodiment introduces an intelligent control module to enable the system to adjust itself in various environments and ensure long-term stable operation. The existence of the protection unit can effectively prevent failures or damage caused by external conditions; through the coordinated work of the sensor unit and the control unit, the refined management and real-time regulation of each part of the system can be achieved, which can effectively reduce energy loss and improve the overall energy conversion efficiency.

[0098] The remote control unit provides flexible operation mode, allowing users to monitor and manage the operating status of the system anytime and anywhere, thus facilitating daily maintenance and troubleshooting. The addition of the energy management unit not only improves the energy absorption capacity of the system, but also makes it suitable for more types of environments.

[0099] Embodiment 3:

[0100] As attached Figure 3 As shown, the difference from the above embodiment is that an electric energy conversion system based on solar radiation energy and natural fluid thermal energy consists of the following parts: a solar radiation thermal energy collection device 1, a thermal energy storage device 2, a bubble buoyancy turbine device 3 for converting thermal energy into kinetic energy, a heat exchange tube 4 connecting the thermal energy storage device 2 and the bubble buoyancy turbine device 3, a generator 5 driven by the bubble buoyancy turbine device, a gas compressor 6 driven by the bubble buoyancy turbine device, an inner evaporator 7 for absorbing gas heat placed in the bubble buoyancy turbine device 5, an outer evaporator 8 for absorbing natural environment fluid heat placed outside the bubble buoyancy turbine device 5, a condenser 9 for releasing heat placed in the thermal energy storage device 2, an expansion valve 10 connected to the evaporator 7, 8 and the condenser 9 respectively, a pipeline 11 connecting the inner evaporator 7, the outer evaporator 8, the condenser 9 and the gas compressor 6, and an intelligent control module.

[0101] The system converts solar radiation energy and natural fluid thermal energy into electrical energy in the following way:

[0102] ① After the solar radiation heat energy collection device 1 receives the heat energy generated by the sunlight, it continuously conducts the heat energy to the glycerol aqueous solution 12 in the thermal energy storage device 2 through the pipeline 11 and the heat-conducting liquid in the pipeline 11, so that the water temperature gradually rises.

[0103] ② When the water temperature of the thermal energy storage device 2 rises, the heat exchange tube 4 connecting the thermal energy storage device 2 and the bubble buoyancy turbine device 3 transfers heat to the dichloromethane 13 in the bubble buoyancy turbine device 3. When the surface temperature T1 of the heat exchange tube 4 exceeds the boiling point T2 of the dichloromethane 13, the dichloromethane 13 on the surface of the heat exchange tube 4 vaporizes and converts into gas.

[0104] ③ The generated gas is introduced into nine semi-enclosed rectangular containers immersed in liquid dichloromethane 13 and filled with liquid. The nine containers filled with gas move upward due to buoyancy, and discharge the gas and dichloromethane 13 inside the containers in sequence when they reach the highest point they can reach. Subsequently, several empty containers move downward under the action of gravity and sink into the liquid dichloromethane 13. During the sinking process, the empty containers are filled with dichloromethane 13 again until they reach the lowest point they can reach. This process is repeated continuously.

[0105] ④ The container that reciprocates up and down in the bubble buoyancy turbine device 3 drives two rotating shafts to rotate through a transmission chain, one of the rotating shafts drives the generator 5 to generate electricity, and the other rotating shaft drives the gas compressor 6 to work.

[0106] ⑤ The gaseous n-hexane 14 flowing into the gas compressor 6 through the pipeline 11 is compressed and heated by the gas compressor 6 to a temperature T3, T3 is higher than the boiling point T2 of 13, and the n-hexane 14 flows through the heat-releasing condenser 9 placed in the thermal energy storage device 2, and the heat is transferred to the glycerol aqueous solution 12 of the thermal energy storage device 2, and the temperature is reduced to T4. Subsequently, the n-hexane 14 flows through the expansion valve 10 and becomes a low-temperature and low-pressure gas-liquid mixture, and its temperature is reduced to T5 and T5 is lower than 0 degrees Celsius. The low-temperature n-hexane 14 flows into the inner evaporator 7 placed in the bubble buoyancy turbine device 3 and the outer evaporator 8 placed outside the bubble buoyancy turbine device 3 respectively. The n-hexane 14 absorbs the heat in the environment and vaporizes. The temperature rises to T6 and then flows back to the gas compressor 6. At the same time, the inner evaporator 7 reduces the dichloromethane 13 gas generated in ③ and liquefies it and flows back to the bubble buoyancy turbine device 3. This process is repeatedly cycled under the drive of the rotating shaft.

[0107] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
