DETAILED DESCRIPTION
[0037] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0039] It should be understood that when an element or layer is referred to as being "on, adjacent to, connected to or coupled to other elements or layers, it may be directly on, adjacent to, connected to or coupled to other elements or layers, or there may be intervening elements or layers. On the contrary, when an element is referred to as being "directly on, directly adjacent to, directly connected to or directly coupled to other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, doping types and / or parts, these elements, components, regions, layers, doping types and / or parts should not be limited by these terms. These terms are merely used to distinguish one element, component, region, layer, doping type or part from another element, component, region, layer, doping type or part. Therefore, without departing from the teachings of the present invention, the first element, component, region, layer, doping type or portion discussed below may be represented as a second element, component, region, layer or portion; for example, the first doping type may be referred to as the second doping type, and similarly, the second doping type may be referred to as the first doping type; the first doping type and the second doping type are different doping types, for example, the first doping type may be P-type and the second doping type may be N-type, or the first doping type may be N-type and the second doping type may be P-type.
[0040] Spatially relative terms such as "under," "beneath," "below," "under," "above," "above," and the like may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that, in addition to the orientations shown in the figures, spatially relative terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.
[0041] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that when the terms "consisting of" and / or "comprising" are used in this specification, the presence of the features, integers, steps, operations, elements and / or parts can be determined, but the presence or addition of one or more other features, integers, steps, operations, elements, parts and / or groups is not excluded. At the same time, when used herein, the term "and / or" includes any and all combinations of the relevant listed items.
[0042] Embodiments of the invention are described herein with reference to cross-sectional views which are schematic diagrams of ideal embodiments (and intermediate structures) of the invention, such that variations in the shapes shown due to, for example, manufacturing techniques and / or tolerances are anticipated. Thus, embodiments of the invention should not be limited to the specific shapes of the regions shown herein, but rather include deviations in shapes due to, for example, manufacturing techniques. For example, an implanted region shown as a rectangle typically has rounded or curved features and / or an implant concentration gradient at its edges rather than a binary change from an implanted region to a non-implanted region. Similarly, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation is performed. Thus, the regions shown in the figures are schematic in nature, their shapes do not represent the actual shape of the region of the device, and do not limit the scope of the invention.
[0043] Nuclear energy, as a stable, durable, clean and safe energy source, can be used as the main energy source for ocean development to meet the energy needs of exploration and mining equipment for marine mineral resources. Nuclear energy can also serve as a long-term and stable energy guarantee for deep-sea space stations.
[0044] However, the load of the load equipment fluctuates greatly and the power demand is unstable. When nuclear energy is used as the energy supply module to provide electrical energy for the load equipment, the output power of the nuclear reactor needs to be changed frequently to meet the power demand of the load equipment. Frequent changes in the output power of the nuclear reactor will cause safety hazards to the nuclear reactor. Therefore, there is an energy regulation imbalance between the energy output characteristics and the power load demand of the load equipment. The output power of the energy supply module is difficult to adapt to the power required by the load equipment, which in turn causes energy regulation imbalance and complex energy regulation, reducing the utilization rate and applicability of energy. At the same time, there is a problem of damage to the load equipment due to excessive input power.
[0045] This application embodiment provides an energy control system. Figure 1 The energy control system may include: a nuclear energy supply module 100, an energy conversion module 200, a first control module 300 and a molten salt energy storage module 400, wherein the nuclear energy supply module 100 is used to provide thermal energy, the nuclear energy supply module 100 includes a first output end and a second output end, the input end of the energy conversion module 200 is connected to the first output end of the nuclear energy supply module 100, and the energy conversion module 200 is used to convert at least part of the thermal energy into electrical energy, wherein the target output power of the energy conversion module 200 is the first power, and when all the thermal energy is used to convert In the case of electric energy, the output power of the energy conversion module 200 is the second power, the first control module 300 is used to compare the first power with the second power, and when the first power is less than the second power, an energy storage signal is generated, the molten salt energy storage module 400 is communicatively connected to the first control module, the input end of the molten salt energy storage module 400 is connected to the second output end of the nuclear energy supply module 100, and when the molten salt energy storage module 400 receives the energy storage signal, the molten salt energy storage module 400 is used to obtain and store at least part of the heat energy transmitted by the nuclear energy supply module 100.
[0046] Exemplarily, the nuclear energy supply module 100 includes a nuclear reactor. Specifically, in this embodiment, the nuclear reactor is a micro gas-cooled reactor based on TRISO (TRISO Fueled Micro Modular Reactor) fuel, and the reactor core is an integrated graphite matrix, which includes multiple columnar TRISO diffusion zones, multiple capillary heat pipes, multiple lithium expansion modules for controlling reactivity under operating conditions, multiple lithium injection modules for emergency shutdown under accident conditions, and safety rods for reactor startup. TRISO particles are directly dispersed in multiple columnar fuel diffusion zones in the core graphite matrix. The graphite matrix has the advantages of high temperature resistance and good thermal conductivity, so the heat of the fuel inside the core can be transferred out. Dozens of capillary heat pipes are inserted into the graphite matrix to axially export the core heat to the semiconductor thermoelectric conversion module at the top of the core. Semiconductor thermoelectric conversion modules are also arranged around the core container to receive the heat radially exported from the core. The fuel used in the core of this embodiment has a long combustion time, and uses high-temperature resistant (above 1600°C) TRISO fuel and helium for cooling, which can achieve extremely high temperature medium fluid output, thereby enabling the nuclear energy supply module 100 to provide stable thermal energy for a long period of time. Silicon carbide (SiC) can be used as a fuel support component but is not limited to it. Silicon carbide has the advantages of high thermal conductivity, radiation resistance, high strength, etc., and can provide a lightweight and strong support structure for the fuel.
[0047] It should be noted that, because it is difficult to achieve human intervention in the deep sea environment, the nuclear power energy system needs to have a certain degree of autonomy and maintainability to ensure long-term safe and stable operation and emergency response measures. The graphite matrix can also include multiple lithium expansion modules for controlling reactivity under operating conditions, in which the liquid lithium metal will expand and contract with the change of the core temperature, so that it can enter and exit the core as a neutron absorber, thereby achieving the regulation of the core reactivity. The graphite matrix can also include multiple lithium injection modules for introducing shutdown reactivity under accident conditions. In the event of an accident, its fuse switch will be blown due to high temperature, and the liquid lithium metal in the module will be quickly pressed into the core by the pressurized nitrogen, thereby introducing a large amount of negative reactivity into the core, and achieving a rapid emergency shutdown. The center of the graphite matrix can also include one or more safety rods, which can be withdrawn when the reactor is started and serve as a second emergency shutdown system.
[0048] Exemplarily, the energy conversion module 200 may use, but is not limited to, a Stirling thermoelectric conversion device to convert the thermal energy provided by the nuclear energy supply module 100 into electrical energy. The working principle of the Stirling thermoelectric conversion device follows the Stirling thermodynamic cycle, with the Stirling engine as the main structure, and the coupled generator jointly determines the overall performance. The Stirling thermoelectric conversion device includes two pistons as moving parts. When working, the two pistons perform cyclic linear motion to realize the conversion of thermal energy into mechanical energy, and then convert the mechanical energy into electrical energy through the generator.
[0049] Exemplarily, the target output power of the energy conversion module 200 is the first power. Specifically, the first power can be set according to the actual input power of the load device to achieve the first power output by the energy conversion module 200 to be adapted to the load device, thereby avoiding the problem of damage caused by excessive input power of the load device. In the case where all the thermal energy is used to convert into electrical energy, the output power of the energy conversion module 200 is the second power. The magnitude of the second power depends on the magnitude of the heat provided by the nuclear energy supply module 100. Specifically, the magnitude of the second power can be determined by the total heat provided by the fuel of the nuclear energy supply module 100.
[0050] Exemplarily, the first control module 300 is used to compare the first power with the second power, and generate an energy storage signal when the first power is less than the second power. The first control module 300 can generate an energy storage signal when the thermal energy provided by the nuclear energy supply module 100 is greater than the energy required by the load equipment, and then store the remaining energy through the molten salt energy storage module 400 to achieve efficient use of energy.
[0051] Exemplarily, the molten salt energy storage module 400 can adopt but is not limited to molten salt energy storage. Molten salt energy storage is a technology that converts energy into heat energy and stores heat energy in molten salt. Molten salt energy storage uses high-temperature molten salt, such as magnesium chloride, potassium chloride, etc. as storage media. When the power demand is low, renewable energy such as nuclear energy, solar energy, etc. are used to heat the salt storage system and store heat energy in molten salt. When the power demand increases, the stored heat energy is extracted and converted into electrical energy through heat transfer fluid for use in the power grid. Due to the low vaporization pressure and high boiling point of molten salt, molten salt can be used as an ideal heat storage medium and can be operated without the need for a pressurized container.
[0052] The energy control system of the present application includes a nuclear energy supply module 100, an energy conversion module 200, a first control module 300 and a molten salt energy storage module 400, wherein the nuclear energy supply module 100 is used to provide thermal energy, the nuclear energy supply module 100 includes a first output end and a second output end, and the input end of the energy conversion module 200 is connected to the first output end of the nuclear energy supply module 100, and is used to convert at least part of the thermal energy into electrical energy, realize the transformation of the energy form, and further realize the direct power supply to the load device. The target output power of the energy conversion module 200 is the first power, and the first power can be adapted to the input power of the load device to ensure that the load device works under a constant input power, so as to improve the stability of the input power of the load device and avoid the problem of damage to the load device due to unstable input power. In the case where all the thermal energy is used to convert into electrical energy, the output power of the energy conversion module 200 is the second power, and the first control module 300 can compare the size of the first power and the second power. When the first power is less than the second power, it means that the heat provided by the nuclear energy supply module 100 can meet the power supply of the load equipment, and the heat energy provided by the nuclear energy supply module 100 is excessive, so the energy storage signal generated by the first control module 300 can further control the molten salt energy storage module 400 to store the remaining heat energy other than that used for thermoelectric conversion. Therefore, the stability of the output power of the energy control system can be improved, and the excess heat energy can be recovered and stored to avoid energy waste, save energy, improve energy utilization efficiency, and further improve the reliability of the energy control system.
[0053] In some embodiments, see Figure 2 The energy regulation system also includes: a second control module 500, which is used to compare the first power and the second power, and generate an energy transmission signal when the first power is greater than the second power; the molten salt energy storage module 400 is used to connect the first energy storage output end of the molten salt energy storage module 400 to the input end of the energy conversion module 200 when the energy transmission signal is received, and the molten salt energy storage module 400 is used to transmit at least part of the stored thermal energy to the energy conversion module 200 through the first energy storage output end.
[0054] Exemplarily, the first control module 300 can generate an energy transfer signal when the thermal energy provided by the nuclear energy supply module 100 is less than the energy required by the load device, and then the molten salt energy storage module 400 transfers at least part of the stored thermal energy to the energy conversion module 200 through the first energy storage output end. Further, the energy conversion module 200 can convert the thermal energy into electrical energy to power the load device, thereby achieving a stable output power output by the energy conversion module 200 to provide stable electrical energy to the load device.
[0055] The energy regulation system provided in the embodiment of the present application is provided with a first control module 300. When the first power is greater than the second power, the first control module 300 generates an energy transmission signal. When the molten salt energy storage module 400 receives the energy transmission signal, it transmits at least part of the stored thermal energy to the energy conversion module 200 through the first energy storage output terminal. In this way, when the energy provided by the nuclear energy supply module 100 is insufficient, the load device can be powered by the energy stored in the molten salt energy storage module 400, thereby achieving stable operation of the load device, meeting the power demand of the load device, ensuring that the load device operates under a constant input power, and avoiding damage to the load device due to unstable input power.
[0056] In some embodiments, see Figure 1 The heat energy converted by the energy conversion module 200 when outputting the first power is the first heat energy, the heat energy stored by the molten salt energy storage module 400 is the second heat energy, and the heat energy provided by the nuclear energy supply module 100 is equal to the sum of the first heat energy and the second heat energy.
[0057] As an example, the heat energy converted by the energy conversion module 200 when outputting the first power is the first heat energy, the heat energy stored in the molten salt energy storage module 400 is the second heat energy, the heat energy provided by the nuclear energy supply module 100 is equal to the sum of the first heat energy and the second heat energy, and the heat energy input by the energy conversion module 200 and the heat energy stored in the molten salt energy storage module 400 both come from the heat energy provided by the nuclear energy supply module 100. Therefore, the heat energy distribution between the energy conversion module 200 and the molten salt energy storage module 400 can be adjusted to achieve the output power of the energy conversion module 200 being adapted to the input power of the load equipment.
[0058] In the energy regulation system provided in the embodiment of the present application, the heat energy converted by the energy conversion module 200 when outputting the first power is the first heat energy, the heat energy stored in the molten salt energy storage module 400 is the second heat energy, the heat energy provided by the nuclear energy supply module 100 is equal to the sum of the first heat energy and the second heat energy, and the heat energy input by the energy conversion module 200 and the heat energy stored in the molten salt energy storage module 400 both come from the heat energy provided by the nuclear energy supply module 100. Therefore, the output power of the energy conversion module 200 can be adapted to the input power of the load device by adjusting the heat energy distribution between the energy conversion module 200 and the molten salt energy storage module 400, and the residual heat energy provided by the nuclear energy supply module 100 can be stored to improve the reasonable energy distribution rate and energy utilization rate.
[0059] In some embodiments, please refer to Figure 3The energy regulation system also includes: an energy storage monitoring module 600, which is used to obtain the current calorific value of the thermal energy stored in the molten salt energy storage module 400; a third control module 700, which is used to compare the current calorific value with the energy storage threshold of the molten salt energy storage module 400, and generate an energy release signal when the current calorific value is greater than the energy storage threshold; the molten salt energy storage module 400 is used to release part of the stored thermal energy through the second energy storage output terminal when receiving the energy release signal, so that the current calorific value is equal to the energy storage threshold.
[0060] As an example, the third control module 700 may generate an energy release signal when the current calorific value of the thermal energy stored in the molten salt energy storage module 400 is greater than the energy storage threshold, wherein the energy storage threshold may be the maximum value of the heat that the molten salt energy storage module 400 can store, and the energy storage threshold may be set according to the actual situation of the molten salt energy storage module 400. When the molten salt energy storage module 400 receives the energy release signal, the molten salt energy storage module 400 releases part of the stored thermal energy through the second energy storage output terminal so that the current calorific value is equal to the energy storage threshold. Specifically, in this embodiment, the second energy storage output terminal may be connected to seawater to discharge the excess energy storage threshold heat of the molten salt energy storage module 400 into the seawater, so that the thermal energy stored in the molten salt energy storage module 400 does not exceed the energy storage threshold, thereby avoiding safety hazards caused by excessive storage of heat.
[0061] The energy regulation system provided in the embodiment of the present application can release the stored heat when the heat stored in the molten salt energy storage module 400 exceeds the storage limit by setting the energy storage monitoring module 600 and the third control module 700, thereby ensuring the safety of the energy regulation system, and by reasonably setting the storage threshold according to actual conditions, efficient use of energy can be achieved without wasting energy.
[0062] In some embodiments, please refer to Figure 4 The energy control system further includes: a voltage control module 800, which is used to control the output voltage value of the energy conversion module 200 to be equal to the target voltage value.
[0063] As an example, the target voltage value can be set according to the input voltage value required by the actual load device. The voltage control module 800 can make the voltage output by the energy conversion module adapt to the input voltage of the load device by adjusting the output voltage value of the energy conversion module to be equal to the target voltage value.
[0064] The energy regulation system provided in the embodiment of the present application can achieve that the voltage output by the energy conversion module is adapted to the input voltage of the load device by setting the voltage regulation module 800 to regulate the output voltage value of the energy conversion module to be equal to the target voltage value, so as to balance the supply and demand of energy between the nuclear energy supply module 100 and the load device, avoid the problem of the input voltage to the load device being too low due to energy imbalance, resulting in the load device being unable to work normally, and also avoid the problem of damage to the load device due to excessive output voltage.
[0065] In some embodiments, please refer to Figure 4 The voltage control module 800 includes: a comparison unit 801, which is used to compare the target voltage value with the output voltage value of the energy conversion module 200, and generate a first control signal when the target voltage value is smaller than the output voltage value of the energy conversion module 200, and generate a second control signal when the target voltage value is greater than the output voltage value of the energy conversion module 200.
[0066] As an example, the target voltage value is the voltage input by the load device. The target voltage value can be set according to the input voltage requirement of the actual load device. The comparison unit 801 is used to compare the target voltage value with the output voltage value of the energy conversion module 200. When the target voltage value is smaller than the output voltage value of the energy conversion module 200, a first control signal is generated. When the target voltage value is larger than the output voltage value of the energy conversion module 200, a second control signal is generated. In this way, the size information of the target voltage value and the output voltage value of the energy conversion module can be obtained in real time, and whether the output voltage value of the energy conversion module meets the actual requirements of the load device can be understood, so as to further adjust the voltage output of the energy conversion module.
[0067] The energy control system provided in the embodiment of the present application can determine whether the output voltage value of the energy conversion module meets the required voltage value of the load device by setting the comparison unit 801, so as to further adjust the output voltage of the energy conversion module so that its output voltage value is more suitable for the voltage requirement of the load device, thereby maintaining the stable operation of the load device.
[0068] In some embodiments, please refer to Figure 4 The molten salt energy storage module 400 is communicatively connected to the comparison unit 801, and the molten salt energy storage module 400 is connected to the energy conversion module 200. The molten salt energy storage module 400 is used to obtain and store at least part of the thermal energy of the energy conversion module 200 according to the first control signal.
[0069] As an example, the molten salt energy storage module 400 can obtain and store at least part of the thermal energy of the energy conversion module 200 according to the first control signal to transfer the thermal energy of the energy conversion module 200 to the molten salt energy storage module 400, thereby reducing the electric energy output by the energy conversion module 200, and further reducing the output voltage of the energy conversion module 200 to adapt to the input voltage of the load device.
[0070] In the energy regulation system provided in the embodiment of the present application, the molten salt energy storage module 400 obtains and stores at least part of the thermal energy of the energy conversion module 200 according to the first control signal, so as to transfer the thermal energy of the energy conversion module 200 to the molten salt energy storage module 400, thereby reducing the electric energy output by the energy conversion module 200, and further reducing the output voltage of the energy conversion module 200 to adapt to the input voltage of the load device. Further, the molten salt energy storage module 400 can store thermal energy to improve energy utilization.
[0071] In some embodiments, please refer to Figure 4 The molten salt energy storage module 400 is communicatively connected to the comparison unit 801, the molten salt energy storage module 400 is connected to the energy conversion module 200, and the molten salt energy storage module 400 is used to transmit at least part of the heat energy to the energy conversion module 200 according to the second control signal.
[0072] As an example, the molten salt energy storage module 400 can transmit at least part of the thermal energy to the energy conversion module 200 according to the second control signal, so as to transfer the thermal energy stored in the molten salt energy storage module 400 to the energy conversion module 200, thereby increasing the electric energy output by the energy conversion module 200, and further increasing the output voltage of the energy conversion module 200 to adapt to the input voltage of the load device.
[0073] In the energy regulation system provided in the embodiment of the present application, the molten salt energy storage module 400 transmits at least part of the thermal energy to the energy conversion module 200 according to the second control signal, so as to transfer the thermal energy stored in the molten salt energy storage module 400 to the energy conversion module 200, thereby increasing the electric energy output by the energy conversion module 200, and further increasing the output voltage of the energy conversion module 200 to adapt to the input voltage of the load device. Further, the molten salt energy storage module 400 can transfer the stored thermal energy to the energy conversion module 200 to provide thermal energy for the energy conversion module 200, thereby achieving a stable voltage output of the energy conversion module 200.
[0074] In some embodiments, see Figure 5 The energy regulation module further includes: a temperature detection module 900, which is used to detect the temperature of the molten salt energy storage module 400, and generate a temperature control signal when the temperature of the molten salt energy storage module 400 is higher than a preset temperature.
[0075] As an example, the temperature detection module 900 may include but is not limited to an infrared imager, a thermocouple, a thermal resistor, an optical fiber temperature sensor, a nuclear instrument, a temperature probe, a radiation monitor, or a distributed temperature sensor, etc. When the temperature of the molten salt energy storage module 400 is higher than the preset temperature, a temperature control signal is generated to provide a high temperature warning. The preset temperature may be the maximum safe temperature of the molten salt energy storage module 400. Specifically, the preset temperature of the molten salt energy storage module 400 may be set according to actual conditions so that the molten salt energy storage module 400 can operate normally in a safe environment.
[0076] The energy control system provided in the embodiment of the present application detects the temperature of the molten salt energy storage module 400 by setting a temperature detection module 900. When the temperature of the molten salt energy storage module 400 is higher than a preset temperature, a temperature control signal is generated to generate a temperature warning, thereby further maintaining the temperature of the molten salt energy storage module 400 within a safe temperature range, thereby improving the reliability and safety of the energy control system.
[0077] In some embodiments, see Figure 5 The energy regulation module further includes: a cooling module 110, which cools the molten salt energy storage module 400 according to the temperature control signal so that the temperature of the molten salt energy storage module 400 is equal to a preset temperature.
[0078] As an example, the cooling module 110 can use but is not limited to using seawater for cooling. It should be noted that the temperature of seawater is lower than the internal temperature of the molten salt energy storage module 400. Therefore, seawater can be used to transfer the heat of the molten salt energy storage module 400 to reduce the thermal energy of the molten salt energy storage module 400.
[0079] The energy control system provided in the embodiment of the present application cools the molten salt energy storage module 400 through the cooling module 110, and can reduce the temperature of the molten salt energy storage module 400 so that the molten salt energy storage module 400 can operate stably at a safe temperature, thereby improving the safety and reliability of the energy control system.
