Abstract
Description
Technical Field
[0001] This utility model relates to the field of power generation equipment technology, and in particular to a perpetual power generation system for geothermal turbines in hot springs. Background Technology
[0002] In Organic Rankine Cycle (ORC) power generation systems, pumps are typically used to transport the working medium to complete the cycle. The ORC is a thermodynamic cycle that generates electricity using a low-temperature heat source (such as industrial waste heat, geothermal energy, or solar energy). Its core principle is the conversion of thermal energy into mechanical or electrical energy through a phase change of the working medium (usually an organic medium, such as a refrigerant or silicone oil). In this process, the pump plays a crucial role, responsible for transporting the low-temperature, low-pressure working medium from the condenser to the evaporator, thus completing the closed loop.
[0003] However, despite the pump's indispensable role in the system, insufficient airtightness is a common problem in actual operation. Because the working medium in an organic Rankine cycle system typically has a low boiling point and high volatility, it is prone to evaporation and leakage if even minor gaps or poor sealing at connections exist. This leakage not only reduces the total amount of working medium in the system, affecting the continuity of the cycle, but also reduces the overall heat exchange efficiency of the system. Utility Model Content

[0015] In one embodiment, a liquid ejector is provided at one end of the condenser that is connected to the flash evaporator for spraying the condensate formed by heat exchange into the flash evaporator.
[0016] In one embodiment, a one-way check valve is provided between the condenser and the flash evaporator, and the flow direction of the one-way check valve is from the condenser to the flash evaporator.

By adding a flash evaporator between the condenser and the power generation system, and through which the flash evaporator contacts the geothermal well, the design of the flash evaporator optimizes the sealing structure. Through optimized cooperation between the flash evaporator, condenser, and magnetic levitation generator, a sealed thermodynamic circulation loop is formed, preventing leakage of the working medium. Utilizing the efficient heat exchange of the flash evaporator reduces medium leakage and external energy demand, enabling rapid absorption of heat from the geothermal well, thereby improving the heat exchange efficiency of the entire power generation system.

[0028] This utility model proposes a perpetual power generation system 20 for geothermal turbines in hot springs.
[0029] Please see Figure 1 In one embodiment of this utility model, the geothermal turbine perpetual power generation system 20 includes a thermal circulation system 10 and a power generation system 20. The thermal circulation system 10 includes a condenser 11 and a flash evaporator 12. The condenser 11 and the flash evaporator 12 are connected. One end of the flash evaporator 12 is used to connect to the geothermal well 1, and one end of the condenser 11 is used to connect to the heat dissipation component. The power generation system 20 is connected between the condenser 11 and the flash evaporator 12 and is connected to the condenser 11 and the flash evaporator 12 to form a thermal circulation loop.
[0030] The thermal cycle system 10 is the core of the entire power generation system 20, consisting of a condenser 11 and a flash evaporator 12. The flash evaporator 12 is a key component of the system, used to absorb heat from the geothermal well 1. The working medium is heated in the flash evaporator 12 and rapidly evaporates into a high-pressure gas. The flash evaporator 12 is designed to optimize heat exchange efficiency and reduces leakage of the working medium through a sealed structure. The condenser 11 is responsible for cooling and reliquefying the high-pressure gas. It also contains a heat exchanger to release heat from the gas. One end of the condenser 11 is connected to a heat dissipation assembly, which dissipates heat into the environment, ensuring that the working medium can be efficiently liquefied and returned to the flash evaporator 12.
[0031] The power generation system 20 consists of a magnetically levitated generator 22, which is coupled to the thermodynamic cycle system 10. The magnetically levitated generator 22 utilizes the mechanical energy of the turbine to efficiently convert thermal energy into electrical energy. The application of magnetic levitation technology reduces mechanical friction, improves power generation efficiency, and extends equipment life.
[0032] The heat energy provided by the geothermal well 1 is transferred to the flash evaporator 12. The working medium absorbs heat in the flash evaporator 12 and rapidly evaporates into high-pressure gas. This high-pressure gas is injected through a steam ejector 50 to a turbine, driving the turbine to rotate. The turbine's mechanical energy is converted into electrical energy by a magnetic levitation generator 22. The application of magnetic levitation technology reduces energy loss and improves power generation efficiency. The gas, after performing work, continues into the condenser 11, where it releases heat and re-liquefies. The condenser 11 is connected to a heat dissipation assembly to ensure that heat is effectively dissipated into the environment. The liquefied working medium flows back to the flash evaporator 12, completing a thermodynamic cycle. The entire system, through its closed design and optimized sealing structure, ensures the recycling of the working medium, reducing leakage and external power supply requirements.
[0033] This invention adds a flash evaporator 12 between the condenser 11 and the power generation system 20, and the flash evaporator 12 contacts the geothermal well 1. In this way, the design of the flash evaporator 12 optimizes the sealing structure. By optimizing the cooperation of the flash evaporator 12, the condenser 11 and the magnetic levitation generator 22, a sealed thermodynamic circulation loop is formed, which avoids leakage of the working medium. The efficient heat exchange of the flash evaporator 12 reduces the leakage of the medium and the external energy supply demand. It can quickly absorb the heat provided by the geothermal well 1, thereby improving the heat exchange efficiency of the entire power generation system 20.
[0034] In one embodiment, please refer to Figure 1 The flash evaporator 12 is equipped with a first heat exchanger 121, which is used to absorb heat and flash the working medium into gas.
[0035] The flash evaporator 12 is a key component of the thermal cycle system 10. Its internal structure is designed to contain the working medium and provide a low-pressure environment, allowing the working medium to evaporate rapidly after absorbing heat. The outer shell of the flash evaporator 12 is made of high-temperature and corrosion-resistant materials, ensuring long-term stable operation under high-temperature and high-pressure environments. It features a multi-layered sealing structure and pressure regulating device to effectively reduce leakage of the working medium while maintaining pressure balance within the system. The first heat exchanger 121 is installed inside the flash evaporator 12 and is in direct contact with the working medium. Its material selection (such as pure copper or molten salt) ensures efficient heat transfer performance, enabling the heat from an external heat source to be transferred to the working medium in a short time. The structural design of the heat exchanger (such as spiral or flat plate type) further optimizes heat transfer efficiency, ensuring uniform heating of the working medium and rapid conversion into high-pressure gas. Furthermore, the surface of the heat exchanger undergoes special treatment, providing anti-scaling and anti-corrosion properties, extending its service life.
[0036] The heat energy generated by an external heat source (such as a geothermal well 1) is transferred to the first heat exchanger 121 inside the flash evaporator 12. The first heat exchanger 121 rapidly absorbs the heat and transfers it to the working medium in the flash evaporator 12. After absorbing heat, the working medium rapidly evaporates into high-pressure gas due to the low-pressure environment inside the flash evaporator 12. The generated high-pressure gas is transported to the turbine. The turbine uses the expansion force of the gas to do work, driving the magnetic levitation generator 22 to rotate, converting mechanical energy into electrical energy. The application of magnetic levitation technology reduces frictional losses between the turbine and the generator, improving energy conversion efficiency. The low-pressure gas after doing work enters the condenser 11. The condenser 11 releases the heat in the gas into the environment, causing the gas to reliquefy. The liquefied working medium flows back to the flash evaporator 12, completing a closed thermodynamic cycle.
[0037] The first heat exchanger 121 uses highly efficient heat-conducting materials such as pure copper or molten salt, which significantly improves heat transfer efficiency and reduces heat loss. The working medium can evaporate with relatively low heat input, thereby reducing the system's demand for external power and improving overall energy utilization efficiency.
[0038] This embodiment achieves efficient heat exchange and rapid evaporation of the working medium by incorporating a first heat exchanger 121 within the flash evaporator 12, significantly improving the efficiency and capacity of the thermal cycle. The material selection and structural design of the first heat exchanger 121 ensure rapid heat transfer and uniform distribution, while the sealing and pressure regulation mechanisms of the flash evaporator 12 guarantee system stability and medium recycling. This design not only reduces system operating costs and maintenance requirements but also enhances its adaptability and flexibility under different environmental conditions, providing reliable technical support for the geothermal turbine perpetual power generation system 20.
[0039] In one embodiment, please refer to Figure 1The first heat exchanger 121 includes a main heat exchanger 121a and a plurality of heat exchange tubes 121b, one end of each of the plurality of heat exchange tubes 121b being connected to the main heat exchanger 121a.
[0040] The main heat exchanger 121a is the core component of the first heat exchanger 121, typically made of a highly efficient thermally conductive material (such as pure copper or molten salt). Its primary function is to collect and distribute heat, ensuring that heat is uniformly transferred to the working medium. Optionally, the main heat exchanger 121a may be designed with complex flow channels to guide the flow of hot and cold fluids, maximizing heat exchange efficiency. The heat exchange tubes 121b act as a bridge connecting the main heat exchanger 121a and the working medium. These tubes are typically made of high-temperature and corrosion-resistant materials, such as stainless steel or copper alloys. One end of the heat exchange tube 121b is connected to the main heat exchanger 121a, while the other end is in contact with the working medium. The design of the heat exchange tubes 121b (such as spiral, flat, or finned types) aims to increase the surface area, thereby improving heat transfer efficiency.
[0041] The heat energy generated by an external heat source (such as a geothermal well 1) is transferred to the main heat exchanger 121a. The main heat exchanger 121a evenly distributes the heat to each heat exchange tube 121b. Heat exchange occurs between the hot fluid and the working medium within the heat exchange tubes 121b through conduction and convection. The working medium absorbs heat from the heat exchange tubes 121b within the flash evaporator 12, rapidly increasing its temperature and evaporating into a high-pressure gas. This process benefits from the large surface area and high thermal conductivity of the heat exchange tubes 121b, ensuring rapid heat transfer.
[0042] This embodiment sets up a main heat exchanger 121a and multiple heat exchange tubes 121b inside the flash evaporator 12. By optimizing the structure of the heat exchanger and the combined design of the main heat exchanger 121a and heat exchange tubes 121b, the large surface area of the heat exchange tubes 121b and the high-efficiency thermal conductive material ensure that heat can be quickly and evenly transferred to the working medium, reducing heat loss and thus improving the efficiency and capacity of the thermodynamic cycle, thereby enhancing the stability and environmental adaptability of the system.
[0043] In one embodiment, please refer to Figure 1 The flash evaporator 12 is equipped with a heat pipe at the end away from the power generation system 20. The two ends of the heat pipe are a condensation and heat release end and a heat absorption and evaporation end, respectively. The condensation and heat release end is connected to the flash evaporator 12, and the heat absorption and evaporation end is used to insert into the geothermal well 1; and / or, the heat pipe is a straight pipe, a corrugated pipe or a spiral pipe.
[0044] A heat pipe is a highly efficient heat transfer element containing a working fluid (such as water, ammonia, or an organic fluid). The working principle of a heat pipe is based on the phase change process of the working fluid: at the absorber end, the working fluid absorbs heat and evaporates; at the condenser end, the working fluid releases heat and condenses. The high heat transfer efficiency of a heat pipe allows it to transfer a large amount of heat with minimal temperature differences. The condenser end is where the heat pipe connects to the flash evaporator 12. Here, the working fluid inside the heat pipe transfers heat to the working medium in the flash evaporator 12, causing the working medium to evaporate. The design of the condenser end ensures efficient heat transfer while maintaining the thermal balance of the system. The absorber end is where the heat pipe is inserted into the geothermal well 1. Here, the heat pipe absorbs heat from the geothermal well, causing the internal working fluid to evaporate. The absorber end is typically made of high-temperature and corrosion-resistant materials to withstand the high-temperature and high-pressure environment of the geothermal well.
[0045] Heat pipes can be designed as straight pipes, corrugated pipes, or spiral pipes. Different shapes are suitable for different environmental conditions and heat transfer requirements. For example, straight pipes have a simple structure and are suitable for environments with limited space; corrugated and spiral pipes improve heat transfer efficiency by increasing the surface area.
[0046] The heat-absorbing evaporating end is inserted into the geothermal well 1 to absorb heat from the well. The working fluid inside the heat pipe evaporates at the heat-absorbing end, turning into steam and moving towards the heat-releasing condensing end. Upon reaching the heat-releasing condensing end, the steam transfers heat to the working medium in the flash evaporator 12. The working medium absorbs heat and rapidly evaporates into a high-pressure gas. After releasing heat, the steam condenses back into a liquid working fluid and returns to the heat-absorbing evaporating end via capillary action or gravity, completing one heat transfer cycle.
[0047] In this embodiment, a heat pipe is installed at the end of the flash evaporator 12 furthest from the power generation system 20. The heat pipe's absorbing and evaporating end absorbs heat from the geothermal well 1, while its condensing and releasing end transfers heat to the working medium in the flash evaporator 12, ensuring efficient utilization of thermal energy. This configuration allows the heat pipe to achieve highly efficient heat transfer through the phase change process of the working medium, enabling the transfer of a large amount of heat with minimal temperature differences. This design significantly improves the system's heat transfer efficiency and reduces heat loss. Furthermore, the closed structure of the heat pipe and the cyclic use of the working medium ensure long-term stable operation of the system. The heat pipe's high-temperature resistance and corrosion resistance reduce the risk of damage caused by environmental factors, improving the system's reliability.
[0048] In one embodiment, please refer to Figure 1 An insulating pipe 40 is installed outside the heat pipe to keep it warm.
[0049] A heat pipe 40 is a tubular structure made of insulating material, typically using high-insulation materials (such as ceramic fiber, aerogel, or vacuum insulation panels). Its main function is to reduce heat loss during heat transfer, ensuring efficient heat transfer from the absorbing end to the condensing end.
[0050] The heat-absorbing and evaporating end is inserted into the geothermal well 1 to absorb heat from the well. The working fluid inside the heat pipe is heated and evaporated at the heat-absorbing end, turning into steam and moving towards the heat-releasing and condensing end. The insulating pipe 40 is wrapped around the outside of the heat pipe to effectively reduce heat loss during the transfer process.
[0051] In this embodiment, by installing an insulating pipe 40 over the heat pipe, the thermal insulation performance of the insulating pipe 40 significantly reduces heat loss, improves the heat transfer efficiency of the heat pipe, and enhances the overall performance of the system. This design not only enhances the stability and environmental adaptability of the system but also reduces operating costs, providing reliable technical support for the geothermal turbine sustainable power generation system 20.
[0052] In one embodiment, please refer to Figure 1 The condenser 11 is equipped with a second heat exchanger 111, which is used to connect to an external heat dissipation component.
[0053] The second heat exchanger 111, installed inside the condenser 11, is a key connecting component between the condenser 11 and the external heat dissipation assembly. Its main function is to efficiently transfer heat from the condenser 11 to the external heat dissipation assembly. The second heat exchanger 111 is typically made of highly thermally conductive materials (such as aluminum alloy or pure copper) to ensure rapid heat transfer. Its structural design (such as spiral, flat, or finned type) further optimizes heat transfer efficiency. The heat dissipation assembly is the system's external heat dissipation device, used to dissipate the heat transferred by the second heat exchanger 111 into the environment. The heat dissipation assembly can be an air-cooled radiator, a water-cooled radiator, or other types of heat dissipation devices, the specific choice depending on the system's installation environment and heat dissipation requirements.
[0054] Low-pressure gas from the turbine enters the condenser 11 and comes into contact with the second heat exchanger 111. The second heat exchanger 111 transfers heat from the gas to external heat dissipation components, causing the gas temperature to drop and reliquefy. This process ensures that the working medium can be efficiently converted from a gaseous state to a liquid state, preparing it for system recycling. The second heat exchanger 111 transfers heat to the external heat dissipation components, which dissipate the heat into the environment through natural convection, forced convection, or water cooling. For example, an air-cooled radiator uses a fan to accelerate airflow and carry away heat; a water-cooled radiator uses circulating water to transfer heat to an external cooling tower or heat sink.
[0055] In this embodiment, a second heat exchanger 111 is installed inside the condenser 11 and connected to an external heat dissipation component. The high thermal conductivity and optimized structural design of the second heat exchanger 111 ensure that heat can be dissipated quickly, thereby improving the overall performance and stability of the system.
[0056] In one embodiment, please refer to Figure 1The flash evaporator 12 is connected to the power generation system 20 at one end, which is equipped with a steam ejector 50 for injecting the steam generated by heat exchange into the power generation system 20.
[0057] A steam ejector 50 is installed between the flash evaporator 12 and the turbine to efficiently deliver the high-pressure steam generated in the flash evaporator 12 to the turbine. By injecting steam at high speed, the steam ejector 50 ensures that the steam can enter the turbine with sufficient pressure and flow rate, thereby improving the turbine's work capacity.
[0058] Inside the flash evaporator 12, the working medium absorbs heat from the first heat exchanger 121 and rapidly evaporates to form high-pressure steam. A steam ejector 50 is located at the end of the flash evaporator 12 that connects to the power generation system 20, ready to deliver the steam to the turbine. The steam ejector 50 injects the high-pressure steam generated within the flash evaporator 12 at high speed into the turbine. This process is achieved through the special design of the steam ejector 50 (such as nozzles and diffusers) to ensure that the steam enters the turbine at optimal flow rate and pressure.
[0059] In this embodiment, a steam ejector 50 is installed at one end of the flash evaporator 12 that is connected to the power generation system 20. The optimized design of the steam ejector 50 ensures that steam can enter the turbine at the best flow rate and pressure, thereby improving the power generation efficiency and stability of the system.
[0060] In one embodiment, please refer to Figure 1 A liquid ejector 60 is provided at one end of the condenser 11 that is connected to the flash evaporator 12, which is used to spray the condensate formed by heat exchange into the flash evaporator 12.
[0061] A liquid ejector 60 is installed between the condenser 11 and the flash evaporator 12 to efficiently return the condensed liquid to the flash evaporator 12. The liquid ejector 60 ensures that the liquid enters the flash evaporator 12 at sufficient pressure and flow rate by injecting liquid at high speed, thereby improving the system's circulation efficiency. The liquid ejector 60 typically consists of a nozzle, a mixing chamber, and a diffuser, and its design aims to optimize the liquid injection performance.
[0062] The liquid ejector 60 sprays the condensate formed in the condenser 11 at high speed into the flash evaporator 12. The liquid ejector 60 accelerates the liquid through the nozzle, so that it enters the flash evaporator 12 at high pressure and high speed, ensuring that the liquid can be evenly distributed and quickly participate in the next round of heat exchange process.
[0063] In this embodiment, a liquid ejector 60 is provided at one end of the condenser 11 that connects to the flash evaporator 12. The optimized design of the liquid ejector 60 ensures that the condensate can enter the flash evaporator 12 at the best flow rate and pressure, thereby improving the circulation efficiency and stability of the system.
[0064] In one embodiment, please refer to Figure 1A one-way check valve 70 is provided between the condenser 11 and the flash evaporator 12, and the flow direction of the one-way check valve 70 is from the condenser 11 to the flash evaporator 12.
[0065] A one-way check valve 70 is installed between the condenser 11 and the flash evaporator 12 to ensure that the working medium can only flow from the condenser 11 to the flash evaporator 12. Its main function is to prevent backflow of the working medium and maintain stable system operation. The one-way check valve 70 typically consists of a valve body, a valve core, and a spring. The valve core opens or closes under the action of pressure difference to ensure unidirectional flow of the medium.
[0066] The one-way check valve 70 ensures that condensate can only flow from the condenser 11 to the flash evaporator 12, preventing condensate from flowing back into the condenser 11 when the pressure fluctuates. When the condensate pressure exceeds the spring force of the valve core, the valve core opens, allowing condensate to flow into the flash evaporator 12; when the pressure drops, the valve core closes, preventing backflow.
[0067] In this embodiment, a one-way check valve 70 is installed between the condenser 11 and the flash evaporator 12. The one-way check valve 70 ensures that the condensate can only flow from the condenser 11 to the flash evaporator 12, effectively preventing backflow caused by pressure fluctuations, realizing efficient transportation and recycling of condensate, and improving the stability and efficiency of the system.
[0068] In one embodiment, please refer to Figure 1 The power generation system 20 includes a steam turbine 21 and a magnetic levitation generator 22. The steam turbine 21 is located between the flash evaporator 12 and the condenser 11, and the magnetic levitation generator 22 is connected to the steam turbine 21.
[0069] In this process, the flash evaporator 12 flashes to form gas which enters the steam turbine 21 and drives the steam turbine 21 to operate, so that the steam turbine 21 drives the magnetic levitation generator 22 to generate electricity.
[0070] The steam turbine 21 is the core power component of the power generation system 20. Its main function is to convert the thermal and kinetic energy of the high-pressure steam generated by the flash evaporator 12 into mechanical energy. The steam turbine 21 typically consists of a rotor, stator, blades, steam inlet, and steam outlet. The blades on the rotor rotate under the drive of the steam, converting the kinetic energy of the steam into mechanical energy. The stator is used to guide the steam flow and maintain the stable operation of the rotor.
[0071] The magnetic levitation generator 22 is a key component of the power generation system 20, used to convert the mechanical energy generated by the steam turbine 21 into electrical energy. The application of magnetic levitation technology allows the generator's rotor to levitate and rotate without contact, significantly reducing mechanical friction and energy loss. The magnetic levitation generator 22 typically consists of a stator, rotor, magnetic bearings, and electromagnetic coils. The stator contains electromagnetic coils used to generate a magnetic field; the rotor rotates within this magnetic field, cutting magnetic field lines to generate electrical energy.
[0072] Inside the flash evaporator 12, the working medium absorbs heat and evaporates rapidly, forming high-pressure steam. This high-pressure steam is transported through pipes to the inlet of the steam turbine 21. Upon entering the steam turbine 21, the high-pressure steam impacts the blades on the rotor, driving the rotor to rotate. The rotation of the rotor converts the thermal and kinetic energy of the steam into mechanical energy. After the steam performs work by driving the blades, its pressure and temperature decrease, becoming low-pressure steam. The rotor of the steam turbine 21 is connected to the rotor of the magnetic levitation generator 22 via a coupling. When the rotor of the steam turbine 21 rotates, it drives the rotor of the magnetic levitation generator 22 to rotate in the magnetic field generated by the stator, cutting magnetic field lines and inducing current in the stator coils, thus realizing the conversion of mechanical energy into electrical energy. The low-pressure steam after performing work is discharged from the exhaust port of the steam turbine 21 and enters the condenser 11. Inside the condenser 11, the steam releases heat and re-liquefies, forming condensate. The condensate flows back to the flash evaporator 12 through the liquid ejector 60 and the one-way check valve 70, completing a closed thermodynamic cycle.
[0073] In this embodiment, by placing the steam turbine 21 between the flash evaporator 12 and the condenser 11 and connecting it to the magnetic levitation generator 22, the system achieves efficient energy conversion and stable power output. The steam turbine 21 converts the thermal and kinetic energy of the high-pressure steam generated by the flash evaporator 12 into mechanical energy, while the magnetic levitation generator 22 efficiently converts the mechanical energy into electrical energy.
