Description

Technical Field:

[0001] The present invention relates to a method for generating electricity from deep seawater based on ocean thermal energy and pressure difference. Background Art:

[0002] With the continuous growth of global energy demand, ocean energy, as a clean and renewable energy source, has received increasing attention; among them, ocean thermal energy conversion (OTEC) is a technology that uses the temperature difference between surface seawater and deep seawater to generate electricity.

[0003] In the existing ocean thermal energy conversion process, the extraction of deep seawater usually requires specially designed deep-sea pumps, combined with pressure resistance and corrosion resistance characteristics to adapt to the deep-sea high-pressure brine environment; the overall energy consumption of this power generation method is too high, the power generation system design is complex, and during the extraction process, the seawater is only pumped from the deep ocean through pipelines to the seawater utilization equipment, so that part of the flow kinetic energy of the extracted seawater is not effectively utilized, and the overall power generation efficiency is low. Summary of the Invention:

[0004] The embodiment of the present invention provides a method for generating electricity from deep seawater based on ocean thermal energy and pressure difference. The method is reasonably designed. By using the pressure difference between deep seawater and surface seawater, a platform similar to a deep well is built on the ocean surface, and a rigid pipeline is inserted in the middle of the platform to connect the seawater surface with the seawater layer at the target depth; a water-using equipment module is connected to the pool where the platform and the pipeline are connected through a valve. When in use, the valve can be opened, and the seawater in the pool flows to the water-using equipment module. As the surface seawater in the pipeline decreases, the height of the seawater in the pipeline is lower than that outside the pipeline, so that a certain height difference is formed between the seawater outside the pipeline and inside the pipeline, enabling the deep seawater to be naturally pressed into the pipeline and flow upward through the pressure difference. At the same time, a water turbine and a generator set are installed at the pipeline connection. The kinetic energy generated by the upward flow of the deep seawater can be used to drive the water turbine blades, convert the kinetic energy into mechanical energy, drive the coaxial generator to generate electricity and utilize it, so as to make full use of the flow kinetic energy of the extracted seawater, improve the resource utilization efficiency, increase the net output power and revenue of the system. The generated electric energy can not only supply power to the auxiliary equipment of the ocean thermal energy conversion system, but also be applied to the power supply of subsea operations, as well as the lighting and warning systems in the ocean environment, enhancing the visibility of the operating equipment and effectively improving the safety and efficiency of ocean operations, and solving the problems existing in the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A method for generating electricity from deep seawater based on ocean thermal energy and pressure difference, the power generation method comprising the following steps:

[0007] S1. The thermoelectric power generation platform extracts deep seawater in the deep well of the power generation system as the condensation medium;

[0008] S2. Install the water turbine at the connection of the main pipeline for transporting deep seawater and generate electricity by using the kinetic energy generated by the seawater flow; Specifically, when the deep seawater flows in the pipeline, the speed and pressure of the water flow generate a force on the turbine blades, pushing the turbine blades to rotate, driving the connected generator to operate, converting mechanical energy into electrical energy, providing a stable power supply for the offshore operation platform, and supporting the operation of various equipment and facilities;

[0009] S3. Distribute and regulate the output electrical energy; One way is to lead the electrical energy generated by the water turbine to the offshore operation platform through electric wires, and the other way is to set it near the pipeline to drive the marine environment lighting system or emergency warning equipment;

[0018] The high-voltage protection chamber adopts a modular design and is installed at the pipeline connection. The size of the connected opening is the same as the inner diameter of the pipeline. At the end of a section of pipeline, after fixing the high-voltage protection chamber in the form of flange fixation, pipelines are continued to be installed at the other end, so that the number of devices can be adjusted at any time according to the sea current and power consumption requirements, without being restricted by the pipeline length and without damaging the pipeline, increasing the applicability.

[0019] The pipeline adopts a multi-layer structure and uses a super wear-resistant and low-friction inner lining layer and a non-bonding flexible pipe preparation process to ensure its bending strength while the tensile performance should also be able to bear the displacement generated by the high-voltage protection chamber and the water turbine in the ocean.

[0034] With the above structure and method, in the process of deep seawater extraction, the present invention extracts seawater in a large pressure state in the deep seawater area to the surface use area through natural power. And in this process, by installing a water turbine at the lifting pipeline, the kinetic energy generated during the upward flow of seawater is used to generate electricity, and it can make the power maintenance lighting system work normally or support equipment for underwater operations, and can also function as pumps and other energy-consuming equipment used in the entire ocean thermal energy conversion power generation system, increasing the net output of the ocean thermal energy conversion power generation system and improving energy utilization efficiency; the output electrical energy is calculated through the function iteration progression method, and then the performance of the power generation system is evaluated; through the constructed main data model for step-by-step training and verification, by allocating and regulating the output electrical energy, the propulsion system and various sensors can be driven to monitor water quality, temperature, and pressure environment parameters for real-time data transmission to ensure the safety of the ocean environment and the accuracy of monitoring, with the advantages of practicality, high efficiency, energy conservation, and environmental protection.

[0037] To clearly illustrate the technical features of this solution, the present invention will be elaborated in detail below through specific implementation manners and in combination with its drawings.

[0038] As Figure 1 and Figure 2 shown, for the deep seawater power generation method based on ocean thermal energy and pressure difference, the power generation method includes the following steps:

[0039] S1, the ocean thermal energy conversion power generation platform extracts deep seawater as a condensing medium in the deep well of the power generation system;

[0040] S2, install a water turbine at the connection of the main pipeline for transporting deep seawater, and use the kinetic energy generated by the seawater flow to generate electricity; specifically, when deep seawater flows in the pipeline, the flow velocity and pressure of the water flow generate a force on the turbine blades, pushing the turbine blades to rotate, driving the connected generator to operate, converting mechanical energy into electrical energy, providing a stable power supply for the ocean operation platform, and supporting the operation of various equipment and facilities;

[0042] S4, use the function iteration and progression method to calculate the output electric energy, and then evaluate the performance of the power generation system.

[0043] The steps for the ocean thermal energy power generation platform to extract deep seawater as the condensation medium in the deep well of the power generation system are as follows:

[0044] S1.1, set the corresponding pipeline structure and pressure difference valve, and penetrate a rigid pipeline in the deep well device to connect the seawater surface with the seawater layer at the target depth;

[0045] S1.2, only extract the surface seawater in the pipeline on the platform, resulting in the seawater height in the pipeline being lower than that outside the pipeline, prompting the deep seawater to generate a pressure difference on the surface seawater through the height difference and naturally pour into the pipeline, and relying on the density and pressure of the deep seawater to form a pressure difference to drive the deep seawater to flow into the pipeline;

[0046] S1.3, form a continuous water flow in the pipeline to ensure the smooth passage of the water flow and reduce energy loss and resistance.

[0047] Install a high-pressure protection chamber outside the water turbine to prevent the pressure damage caused by the high-pressure environment conditions in the deep ocean to the water turbine;

[0048] The high-pressure protection chamber adopts a double-layer protection structure, with a corrosion-resistant material configured on the outside as the shell and a high-strength alloy used for support on the inside to reduce the direct impact of the seabed pressure on the internal equipment, and a sealing material is used at the equipment joints to ensure that the equipment is not immersed and corroded by seawater and thus damaged.

[0049] The output end of the generator is connected to the high-pressure protection chamber through a cable to lead the electric energy generated by the generator to the subsea equipment or offshore operation platform through electric wires outside the pipeline; at the same time, drive the marine environment lighting system and emergency warning equipment.

[0050] The high-pressure protection chamber adopts a modular design and is installed at the pipeline connection. The connection opening size is the same as the inner diameter of the pipeline; at the end of a section of pipeline, the high-pressure protection chamber is fixed in a flange-fixed form, and then the pipeline is continued to be installed at the other end, so that the number of equipment can be adjusted at any time according to the sea current and power consumption requirements, without being limited by the pipeline length and without damaging the pipeline, increasing the applicability.

[0051] The pipeline adopts a multi-layer structure and uses a super wear-resistant and low-friction inner lining layer and a non-bonding flexible pipe preparation process to ensure its bending strength while the tensile performance should also be able to bear the displacement generated by the high-pressure protection chamber and the water turbine in the ocean.

[0052] The distribution and regulation of the output electric energy can drive the propulsion system and various sensors to monitor the water quality, temperature, and pressure environmental parameters, so as to transmit data in real time and ensure the safety of the marine environment and the accuracy of monitoring.

[0053] Using the function iteration and progression method to calculate the output electric energy, and then evaluating the performance of the power generation system includes the following steps:

[0054] S4.1, Collect the collected electric energy parameters and use the screening function to clean the data and remove noise;

[0055] S4.2, According to the characteristics and requirements of the marine environment, use the modeling function to construct the main data model;

[0056] S4.3, For each electric energy parameter in the main data model, use the iteration function to gradually train and verify the constructed main data model, and then accurately evaluate the performance of the power generation system according to the training results and the number of iterations.

[0057] The screening function is:

[0058]

[0059] Where Q i is the real-time electric energy parameter, and Q e is the standard value of the electric energy parameter;

[0060] The modeling function is:

[0061]

[0062] Where D is a positive parameter, H is the main data model correction coefficient, and P i and T i are the data structure parameter and data constraint parameter of the main data model;

[0063] The iteration function is:

[0064]

[0065] Where m is the number of iterations, S0 is the iteration trigger parameter, h is the standard value of the electric energy parameter iteration parameter, and A is the homogenization constant.

[0066] The working principle of the deep - sea water power generation method based on ocean thermal energy and pressure difference in the embodiments of the present invention is as follows: Utilize the pressure difference between deep - sea water and surface - sea water to build a platform similar to a deep well on the ocean surface. Insert a rigid pipe through the middle of the platform to connect the sea surface and the sea - water layer at the target depth. A water - using equipment module is connected to the pool where the platform and the pipe are connected through a valve. When in use, the valve can be opened, and the sea water in the pool flows to the water - using equipment module. As the surface - sea water in the pipe decreases, the height of the sea water in the pipe is lower than that outside the pipe, resulting in a certain height difference between the sea water outside and inside the pipe. Thus, the deep - sea water is naturally pressed into the pipe and flows upward through the pressure difference. At the same time, a water turbine and a generator set are installed at the pipe connection. The kinetic energy generated by the upward flow of the deep - sea water can be used to drive the blades of the water turbine, convert the kinetic energy into mechanical energy, drive the co - axial generator to generate electricity and utilize it. In this way, the flowing kinetic energy of the extracted sea water can be fully utilized, the resource utilization efficiency can be improved, the net output power and revenue of the system can be increased. The generated electric energy can not only supply power to the auxiliary equipment of the ocean thermal - energy power generation system, but also be applied to the power supply for sub - sea operations, as well as the lighting and warning systems in the ocean environment, enhancing the visibility of the operating equipment and effectively improving the safety and efficiency of ocean operations.

[0067] In the overall solution, the power generation method includes the following steps: The ocean - thermal - energy power generation platform extracts deep - sea water as the condensation medium in the deep well of the power generation system; Install the water turbine at the connection of the main pipe for transporting deep - sea water and generate electricity by using the kinetic energy generated by the flowing sea water. Specifically, when the deep - sea water flows in the pipe, the speed and pressure of the water flow exert forces on the turbine blades, pushing the turbine blades to rotate, driving the connected generator to operate, and converting mechanical energy into electrical energy to provide stable power supply for the ocean operation platform and support the operation of various equipment and facilities; Distribute and regulate the output electrical energy; One way is to lead the electrical energy generated by the water turbine to the ocean operation platform through electric wires, and the other way is to set it near the pipe to drive the ocean - environment lighting system or emergency warning equipment; Use the function iteration and progression method to calculate the output electrical energy, and then evaluate the performance of the power generation system.

[0068] Furthermore, in this application, the pressure difference between deep - sea water and surface - sea water is utilized to make use of the kinetic energy generated by the flowing sea water in the pipe. While collecting deep - sea water, the system can obtain additional energy and generate output. Further utilize the kinetic energy of the flowing sea water in the pipe to generate electricity, increasing the net output power of the system.

[0069] For the deep seawater extraction part, the natural pressure difference between deep seawater and surface seawater is utilized for deep seawater extraction. By designing a special pipeline structure and pressure difference valves, the ocean thermal energy conversion system pumps cold seawater in the well as the condensation medium; in this process, due to the relatively high density and pressure of deep seawater, the formed pressure difference drives the deep seawater to flow into the pipeline.

[0070] Compared with the traditional deep seawater pumping method, this method significantly reduces energy consumption because no additional power device is required to push the water flow; on the contrary, the natural flow of deep seawater can effectively press it into the pipeline to form a continuous water flow. The pipeline structure of this system is designed to ensure smooth water flow, reduce energy loss and resistance; this design not only improves the extraction efficiency but also extends the service life of the equipment. Through reasonable material selection and structure optimization, the pipeline can withstand various pressures and corrosion in the marine environment to ensure long-term stable operation.

[0071] For the kinetic energy conversion part, a water turbine is installed at the connection of the main pipeline for transporting deep seawater to generate electricity using the kinetic energy generated by seawater flow; when deep seawater flows in the pipeline, the speed and pressure of the water flow will exert a force on the turbine blades to drive them to rotate; the design of the turbine blades takes into account the characteristics of the water flow and can maximize the energy conversion efficiency; the rotation of the turbine can drive the connected generator to operate, and then convert mechanical energy into electrical energy. In this way, the water turbine can provide a stable power supply for the offshore platform to support the operation of various equipment and facilities.

[0072] For the electric energy utilization part, there are two ways of power output distribution, namely through electric wires and nearby power supply; the first way is to lead the electric energy generated by the water turbine generator set to subsea equipment or offshore operation platforms through electric wires; this way can effectively transmit the power to subsea operation equipment such as diving operation tools and sensors to provide stable power support for them; the second way is to be used nearby on the pipeline to drive the marine environment lighting system, such as subsea lighthouses or identification lights, and emergency warning devices. The lighting system plays a crucial role in offshore operations and can provide guidance for sailing ships to avoid collisions and accidents. Subsea lighthouses and identification lights can achieve rapid response and efficient energy utilization by being directly connected to the water turbine power generation system. In addition, emergency warning devices can quickly send out alarms in case of accidents to ensure the safety of divers and offshore operation personnel.

[0073] Taking the working process of a submersible robot as an example, when the submersible robot conducts deep-sea exploration, it requires a large amount of electricity to drive its propulsion system and various sensors. And in this application, power supply through electric wires can ensure that it is not limited by the battery level during long-term operation. In addition, the seabed sensors for monitoring environmental parameters such as water quality, temperature, and pressure also rely on a stable power supply to transmit data in real time, ensuring the safety of the marine environment and the accuracy of monitoring.

[0074] Since it is necessary to analyze and evaluate the quality of the generated electric energy, in this application, a function iteration and progression method is used to operate on the output electric energy, which specifically includes the following steps: collecting the collected electric energy parameters and using a screening function to clean the data and remove noise; according to the characteristics and requirements of the marine environment, using a modeling function to construct a main data model; for each electric energy parameter in the main data model, using an iterative function to gradually train and verify the constructed main data model, and then accurately evaluating the performance of the power generation system according to the training results and the number of iterations.

[0075] For the corresponding function algorithms, the screening function is:

[0076]

[0077] where Q i is the real-time electric energy parameter, and Q e is the standard value of the electric energy parameter;

[0078] The modeling function is:

[0079]

[0080] where D is a positive parameter, H is the correction coefficient of the main data model, and P i and T i are the data structure parameter and data constraint parameter of the main data model;

[0081] The iterative function is:

[0082]

[0083] where m is the number of iterations, S0 is the iteration trigger parameter, h is the standard value of the electric energy parameter iteration parameter, and A is the homogenization constant.

[0084] It should be noted especially that in order to prevent the pressure damage to the water turbine caused by the high-pressure environment conditions in the deep sea, a high-pressure protection chamber is installed outside the water turbine. The high-pressure protection chamber adopts a double-layer protection structure, with a corrosion-resistant material configured on the outside as the shell and a high-strength alloy used on the inside for support, reducing the direct impact of the seabed pressure on the internal equipment. And sealing materials are used at the equipment joints to ensure that the equipment is not immersed and corroded by seawater and thus damaged.

[0085] Meanwhile, the output end of the generator is connected to the high-voltage protection chamber through a cable, so as to lead the electric energy generated by the generator to the seabed equipment or the offshore operation platform through electric wires outside the pipeline; the high-voltage protection chamber adopts a modular design and is installed at the pipeline connection. The connection opening size is the same as the inner diameter of the pipeline; at the end of a section of pipeline, after the high-voltage protection chamber is fixed in a flange-fixed form, the pipeline is continuously installed at the other end, so that the number of devices can be adjusted at any time according to the sea current and the power consumption demand, without being limited by the pipeline length and without damaging the pipeline, increasing the applicability.

[0086] In summary, the deep-sea power generation method based on ocean thermal energy and pressure difference in the embodiment of the present invention utilizes the pressure difference between deep seawater and surface seawater to build a platform similar to a deep well on the ocean surface, and a rigid pipeline is penetrated in the middle of the platform to connect the seawater surface and the seawater layer at the target depth; a water-using equipment module is connected to the pool where the platform and the pipeline are connected through a valve. When in use, the valve can be opened, and the seawater in the pool flows to the water-using equipment module. As the surface seawater in the pipeline decreases, the seawater height in the pipeline is lower than that outside the pipeline, so that a certain height difference is formed between the seawater outside the pipeline and inside the pipeline, enabling the deep seawater to be naturally pressed into the pipeline and flow upward through the pressure difference. At the same time, a water turbine and a generator set are installed at the pipeline connection, and the kinetic energy generated by the upward flow of the deep seawater can be used to drive the blades of the water turbine, converting the kinetic energy into mechanical energy, driving the coaxial generator to generate electricity and utilize it, thereby making full use of the flowing kinetic energy of the extracted seawater, improving the resource utilization efficiency, increasing the net output power and revenue of the system. The generated electric energy can not only supply power to the auxiliary equipment of the ocean thermal energy power generation system, but also be applied to the power supply for seabed operations, as well as the lighting and warning systems in the marine environment, enhancing the visibility of the operation equipment and effectively improving the safety and efficiency of marine operations.

[0087] The above specific implementation manners cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the embodiments of the present invention falls within the protection scope of the present invention.

[0088] Those parts not detailed in the present invention are all well-known technologies to those skilled in the art of this technology.
