Description

Technical Field

[0001] The present invention relates to the technical field of energy storage equipment, and in particular to a new energy graphene electric thermal energy storage equipment vehicle. Background Art

[0002] With the growing global demand for clean energy and sustainable development, the application prospects of graphene electrothermal energy storage equipment are becoming increasingly broad. In the industrial sector, it can effectively recover and reuse waste electricity from power plants at night. Power plants generate electricity during the day, but their equipment cannot be shut down at night. A 200,000-kilowatt generator takes approximately 10 hours to fully shut down from rated power. This means that the power plant's equipment hasn't stopped yet, and it's time to generate electricity during the day. In cities, electricity consumption is low at night, whether in factories or homes. As a result, 70% of the electricity generated by power plants at night is wasted electricity that no one uses. Peak shaving and valley filling to increase nighttime electricity consumption is an effective measure for energy conservation and emission reduction in the power grid. The most efficient and feasible way to use electricity at night is through energy storage. Summary of the Invention

[0028] Due to the adoption of the above technology, the present invention has the following positive effects compared with the prior art:

[0029] (1) The present invention is an electric thermal energy storage device based on graphene material, which utilizes the high thermal conductivity of graphene material and the high heat storage characteristics of aluminum or magnesium bricks. Through an electromagnetic coil wrapped around the outside of the heat-resistant steel tank container shell, the heat-resistant steel tank container shell with good magnetic induction is heated to a temperature of 100-1000 degrees Celsius. The high-temperature heat of the heat-resistant steel tank container shell is quickly transferred to the heat-conducting circuit type thermal energy storage composite material of magnesium brick stacking and graphene filling set inside it through the excellent thermal conductivity and heat resistance of graphene powder filled in the gap inside the heat-resistant steel tank container, so as to realize electric heat conversion energy storage, and finally achieve efficient and rapid thermal energy storage and release. Traditionally, magnesium brick energy storage can only be heated by electric heating wire. The comprehensive thermal conversion rate is generally only about 65% or even lower. Moreover, the electric heating wire (nickel-chromium alloy, iron-chromium alloy) will produce an oxidation reaction with high temperature, which reduces the electric heat conversion rate and is more likely to produce cracks and fractures. The maintenance cost is high and basically equivalent to reconstruction. The electromagnetic heating method used in the present invention can achieve a heat conversion rate of up to 90%, which has obvious advantages in terms of energy saving and maintenance. In addition, traditional magnesium brick energy storage is prone to fracture and surface peeling due to thermal stress and oxidation reaction, and its heat storage and heat release functions are greatly reduced after a period of use. The need to replace broken magnesium bricks and disassemble the equipment to repair broken heating wires invisibly increases the energy storage cost significantly. The present invention innovatively uses an indirect heat conduction energy storage method of stacking magnesium bricks and filling the gaps with graphene medium. If the magnesium bricks break during use and movement, the graphene powder will automatically fill the gaps caused by the fracture of the magnesium bricks under the action of gravity and artificial vibration to maintain the original heat storage and heat release capacity of the magnesium bricks. More importantly, the magnesium bricks used in the present invention have 1%-50% graphene powder added during the production process. Its melting point is extremely high (about 3652°C) and it can remain stable at high temperatures. Graphene resists deformation during heating, making it suitable for long-term, high-temperature use. It increases the strength and thermal conductivity of magnesium bricks and effectively prevents cracking and peeling in high-temperature environments. Furthermore, graphene's excellent electrical conductivity effectively generates eddy currents, which rapidly heat the magnesium bricks in electromagnetic fields. These innovative advantages of the present invention are unattainable with traditional magnesium brick energy storage systems using electric heating wires.

[0030] (2) The present invention starts the electromagnetic heating system at night when electricity prices are low. By precisely controlling the heating power and time, the heat storage material is evenly heated to a saturated heat storage state. During the day, when the vehicle is at the original location or traveling to an energy delivery location, the heat exchange unit starts working to provide hot water or hot air as needed, or converts heat energy into electrical energy output through steam turbine power generation;

[0031] (3) In the present invention, electrical energy is smoothly converted into thermal energy for storage through the most energy-saving electromagnetic heating method. The use of graphene achieves a technological leap in high energy density energy storage and heat conduction, improves the energy storage speed, and can provide a large amount of thermal energy in a short time to meet the needs of various application scenarios.

[0045] Electromagnetic heating is a heating method that uses the principle of electromagnetic fields to convert electrical energy into thermal energy. It relies primarily on the electromagnetic field generated by a high-frequency AC power source. The induced magnetic field causes the free electrons in the conductor of the heated object to rapidly vibrate and collide, thereby rapidly converting the electrical energy in the conductor into thermal energy.

[0046] The principle of electromagnetic heating is based on Faraday's law of electromagnetic induction and Joule's law of heating. When a high-frequency power supply is energized, the generated alternating current produces a changing magnetic field in the coil. This changing magnetic field passes through the conductor (usually metal) in the heated object, causing the free electrons in the conductor to be affected by the induction force and begin to move at high speed. Due to the resistance between the free electrons in the conductor, the high-speed movement of the electrons causes them to collide, and the collision converts the kinetic energy of the electrons into heat energy. In this way, the electrical energy in the conductor is converted into heat energy, achieving the heating effect.

[0067] In a further embodiment of the present invention, the present invention greatly improves the efficiency of energy use and reduces environmental pollution. In the future energy development blueprint, graphene aluminum and graphene magnesium brick material energy storage technology is expected to become a bridge connecting renewable energy and modern power grids. Developing a new energy storage method to participate in the operation of the power system and better regulate the power generation function of power equipment is an urgent technical task at present. The present invention is an electric thermal energy storage device based on graphene aluminum or graphene magnesium brick materials. It utilizes the high thermal conductivity of graphene and the high heat storage characteristics of magnesium bricks to perform electric heat conversion by electromagnetic heating of the heat-resistant steel tank body, and adopts the graphene heat conduction method to introduce the 600-degree heat on the surface of the heat-resistant steel tank body into the magnesium bricks stacked inside for energy storage. Achieve efficient and rapid thermal energy storage and release. Compared with traditional thermal energy storage technology, graphene magnesium brick thermal energy storage materials have higher energy storage density and faster energy storage speed, and can provide a large amount of thermal energy in a short time to meet the needs of various application scenarios.

[0068] In a further embodiment of the present invention, graphene magnesium bricks are currently the most ideal thermal energy storage material because organic thermal energy storage materials have a maximum storage temperature of only around 300°C, while the graphene magnesium bricks of the present invention can store heat at over 1000°C. At 800°C, the specific heat capacity of magnesium bricks is 1.12 kJ / kg. Among the many metal materials with thermal energy storage capabilities, aluminum has a melting point of 660°C and absorbs a large amount of heat during melting, resulting in a specific heat capacity of 0.88 kJ / kg. Iron and steel have a specific heat capacity of 0.46 kJ / kg. Copper and zinc both have a specific heat capacity of only 0.39 kJ / kg, and lead is even worse. These materials all have lower specific heat capacities than magnesium bricks. Based on the above data, graphene magnesium bricks are the best thermal energy storage material. However, magnesium bricks are primarily composed of magnesium oxide (MgO), which has very low electrical conductivity. Since magnesium bricks themselves are non-conductive and have weak electromagnetic induction, they cannot be quickly heated for thermal energy storage through electromagnetic heating, which has the highest electrothermal conversion rate. Therefore, it is not feasible to heat magnesium bricks directly through electromagnetic induction. This is also a key technical problem that plagues magnesium brick energy storage devices. The present invention utilizes the property that graphene is the fastest thermal conductor (graphene's thermal conductivity can reach 5104W / m•K, which is much higher than aluminum's thermal conductivity of 237W / m•K and about 21 times that of aluminum. Graphene's thermal conversion rate is as high as 99.7%, and heat loss during its transfer is negligible). Graphene's excellent thermal conductivity is used to quickly transfer 800-degree heat from the surface of the heat-resistant steel tank to the magnesium bricks. This technology effectively solves the disadvantage of magnesium bricks' weak electromagnetic induction. The present invention uses electromagnetic heating to quickly heat a long cylindrical heat-resistant steel tank container with strong electromagnetic induction (the tank has a diameter of 1.2 meters and a length of 9 meters, a tank wall thickness of 3-30 mm, and a fully enclosed electromagnetic heating energy storage module unit is provided every 1.5 meters. The entire device consists of 6 energy storage module units, and a 0.3-meter-wide and 1.2-meter-diameter graphene medium fully isolated binary heat exchange unit is provided between every two module energy storage units. The heat exchange unit and the energy storage module unit are two independent closed cavities that are tightly connected). The energy storage unit of the energy storage device is composed of graphene magnesium brick heat storage material prepared by a special process, an electromagnetic heating system, and silicon-based heat-resistant insulation material.

[0069] In a further embodiment of the present invention, the graphene magnesium brick thermal energy storage material has excellent thermal conductivity and high specific heat capacity. This is because the magnesium brick, after being doped with 1%-50% graphene, overcomes the disadvantage of the magnesium brick being insensitive to magnetism and having a low electric / heat conversion rate during electromagnetic heating. At the same time, because the graphene is sintered inside the magnesium brick and does not come into contact with oxygen, it effectively avoids the oxidation reaction generated during high-temperature energy storage. It can quickly respond to external electromagnetic heating in a relatively short time to convert power into energy, thereby reaching the required energy storage operating temperature.

[0070] In a further embodiment of the present invention, the electromagnetic induction heating system is designed to have a power of 200 kilowatts per module; each device can accommodate 1-6 modules, resulting in a total power of 1200 kilowatts, heating the thermal energy storage material to over 800 degrees Celsius in approximately 3-4 hours. The heat exchange unit of the present invention utilizes high-efficiency and high-safety graphene-based fully isolated binary heat exchange technology. This structure ensures high electron conduction due to the strong covalent bonds between carbon atoms in graphene, through which electrons can freely transfer. This structure contributes to graphene's high electrical and thermal conductivity. Graphene's exceptional thermal conductivity, with a coefficient of thermal conductivity 13 times that of copper and 21 times that of aluminum, maximizes the thermal energy conversion efficiency of the device. This fully isolated binary heat exchange technology ensures the safety of the energy storage device during operation. The tank of the thermal storage device is made of 310S or 316Ti heat-resistant stainless steel, or other metals such as ordinary iron and steel plates. While using electromagnetic coils or thin electromagnetic copper tubes to heat the heat-resistant steel tank wall, which is highly susceptible to electromagnetic induction, the present invention also uses graphene filled between the gaps between the magnesia bricks and between the magnesia bricks and the heat-resistant tank body. This allows the high temperature of up to 800 degrees generated by the tank steel wall and the electromagnetic field to be quickly introduced into the interior of the graphene magnesia brick thermal energy storage material with minimal heat loss, thereby storing a large amount of heat energy within the magnesia brick. In addition, the graphene fired in the graphene magnesia brick is electromagnetically heated in the heat-resistant steel tank body using an industrial frequency of 50Hz-1kHz (low frequency), which has the greatest electromagnetic penetration and heating depth, and can also effectively generate heat with the electromagnetic field. The present invention smoothly converts electrical energy into thermal energy storage through the most energy-efficient electromagnetic heating method, effectively overcoming the disadvantage of the low thermal conductivity of ordinary magnesia bricks, which affects the heat storage and heat release efficiency, and achieving a technological leap in high-energy-density graphene magnesia brick energy storage composite materials. In the specific implementation, we convert the waste electricity from wind power, solar power, and thermal power plants at night into heat energy through electromagnetic heating and store it in graphene magnesium brick thermal energy storage materials. During the day, the heat or electricity is output in the form of hot water, hot air, steam or steam turbine power generation and thermal cooling. Its rapid response capability and high-efficiency electricity / heat energy conversion characteristics can balance the fluctuation disadvantages of solar and wind power generation and ensure the stable operation of the power grid. The application scenarios of the present invention include winter heating in residential areas or buildings, heating in bathing centers, wood drying, papermaking, printing, pharmaceuticals, chemicals, textiles and more than 20 other industries. The equipment can store 8,000 kWh of thermal energy each time and can store nearly 3 million kWh of thermal energy a year, which is equivalent to saving about 1,000 tons of coal consumption in coal-fired power plants. The service life of the equipment of the present invention is more than 15 years, which can meet the needs of daily production and life. This not only improves the efficiency of energy utilization, but also reduces the consumption of traditional non-renewable energy, further promoting the healthy development of social progress.

[0071] In a further embodiment of the present invention, the application of the graphene energy storage device of the present invention may also be extended to the field of electric vehicles. With the popularization of electric vehicles, the demand for efficient and fast charging technology is increasing. The graphene energy storage device can not only provide a fast and feasible charging solution for electric vehicles on highways, but also reduce the waste of electric power resources through its efficient energy conversion capabilities. Compared with the currently popular battery energy storage technology, it has obvious advantages in use. Although battery energy storage is convenient and practical, its disadvantage is that the battery storage capacity decreases significantly after 3-5 years of use, and the cost of replacing the battery is huge and not worth the cost. The graphene magnesium brick thermal energy storage material of the present invention has a lifespan of more than 15 years, and has the advantage of long service life that other energy storage methods do not have. It can optimize the energy structure, reduce dependence on high-carbon energy such as coal and oil, help reduce greenhouse gas emissions, and contribute to sustainable development.

[0072] In a further embodiment of the present invention, the present invention is an energy storage and electrothermal conversion system with excellent performance, which uses electromagnetic heating technology to heat graphene magnesium brick thermal energy storage materials to a thermal energy storage state, and the temperature can be as high as about 800 degrees. This high temperature state enables the material to store a large amount of thermal energy, which is then converted into hot water, hot gas or driven to generate electricity through a heat exchange unit, thereby achieving a variety of energy outputs. The present invention adopts FCS and PLC intelligent and networked control systems to achieve automated control. As a two-dimensional material with excellent mechanical properties, electrical properties and thermal conductivity, graphene's excellent performance has enabled it to play an effective role in the development of new energy and smart grids. Graphene's single atomic layer structure and a large number of exposed chemical bonds make rapid absorption of electromagnetic waves and heat conduction possible, overcoming the shortcomings of ordinary magnesium brick materials that are slow to generate heat when electromagnetically heated due to their non-magnetic characteristics. Graphene magnesium bricks are made by adding graphene to a magnesium brick body. After sintering and solidifying, the resulting composite thermal energy storage material is obtained. During energy storage, the graphene magnesium bricks are electromagnetically heated using cheap waste electricity from power plants at night, allowing them to absorb large amounts of heat energy and store it in the graphene magnesium brick thermal energy storage material. The material is then transported from the energy storage power source (factory, thermal power plant, wind power plant, solar power plant, or other cheap power source) to the energy use destination, either in situ or by vehicle, to output hot air, hot water, hot air, and turbine power generation. In general, graphene energy storage equipment is a new type of energy device with broad application prospects. Its main functions include electromagnetic heating, automated control, and graphene medium fully isolated binary heat exchange technology, which can achieve efficient, environmentally friendly, and safe energy output.

[0073] In a further embodiment of the present invention, a specific implementation scheme of the graphene energy storage device is as follows:

[0074] The present invention includes the following steps: First, the graphene magnesium brick thermal energy storage material is loaded into a sealable heat-resistant steel tank container, with the container filled to five-sixths of the capacity, leaving one-sixth of the space for thermal expansion and contraction of the thermal energy storage material. The exterior of the tank is wrapped with a silicon-based heat-resistant insulation material with a heat resistance of more than 2000 degrees to prevent heat loss. This ensures that after the device is shut down for saturated energy storage, the temperature of the graphene magnesium brick thermal energy storage material, which is at around 600-1000 degrees, drops by about 15-20 degrees per hour. The present invention activates the electromagnetic heating system at night when electricity prices are low. By precisely controlling the heating power and time, the thermal energy storage material is uniformly heated to a thermal saturation state. When all the graphene magnesium brick thermal energy storage materials reach the preset thermal saturation state, the device stops working. During the day, when the device is at its original location or traveling to an energy transmission site, the heat exchange unit starts working, providing hot water or hot air as needed, or converting thermal energy into electrical energy output through steam turbine power generation.

[0075] The control system utilizes a fieldbus control system (FCS) and a programmable logic controller (PLC) to achieve intelligent management of the entire energy storage vehicle. The FCS is responsible for real-time data acquisition and processing, monitoring various parameters such as temperature, pressure, and flow rate to ensure stable system operation. The PLC is used for automated control, including heating power adjustment, heat exchange unit switching, and energy output mode selection. Networking and informationization are also key features of this invention. By integrating advanced communication modules, the energy storage vehicle can connect to a remote monitoring center in real time, uploading operating data and receiving dispatch instructions. Display screens within the energy storage vehicle and at the company's control center monitor the vehicle's location and operating status in real time based on information collected by various sensors and the Beidou navigation positioning system. Operators can remotely monitor the equipment's operating status via mobile phones or computers, perform fault diagnosis, and conduct maintenance interventions. In the event of a crisis, an alert is immediately sent to on-site staff and the company's remote on-duty monitoring personnel, urging them to address the problem immediately. Remote on-duty personnel can also remotely control the equipment and conduct crisis interventions based on the crisis, achieving dual security monitoring.

[0076] Graphene energy storage devices, with their efficient energy conversion capabilities, intelligent control and management systems, and convenient network information services, offer a novel solution for modern energy supply. They possess broad application prospects in areas such as industrial waste power utilization, factory energy supply, urban heating, highway charging for new energy vehicles, and emergency energy security.

[0078] In a further embodiment of the present invention, the new energy graphene electric thermal energy storage equipment vehicle is used to realize electric thermal energy storage at night, so as to facilitate power generation during the day and realize the reuse of waste electricity at night, that is, the electromagnetic coil 6 is energized by the power supply system at night, and the electromagnetic coil is wound around the outside of multiple first cavities. The heat-resistant steel tank container of the first cavity itself and the graphene magnesium bricks inside it are heated by electromagnetics to realize the energy storage function, that is, electrical energy is converted into thermal energy. During the day, the electromagnetic flow valve 20 and the electromagnetic water supply control valve 21 are opened, and the multiple intelligent pressure level transmitters 3 are monitored in real time through the control system to control the water level height in the multiple heat exchange tube groups 19. The heat energy stored in the graphene magnesium bricks in the first cavity is used to heat the water in the heat exchange tube group 19 into water vapor, and then the water vapor is used to drive the generator set 1 to realize the power generation function.

[0079] In a further embodiment of the present invention, the outer surfaces of the multiple heat-resistant steel tank containers of the shell 2 are all covered with a heat-resistant insulation layer, and the material of the heat-resistant insulation layer is a silicon-based heat-resistant insulation material, which neither affects the electromagnetic heating of the graphene magnesium bricks in the multiple first cavities by the electromagnetic coil 6, nor improves the insulation performance of the heat-resistant steel tank containers and reduces the cooling rate of the graphene magnesium bricks.

[0080] In a further embodiment of the present invention, the interiors of multiple second cavities are filled with a heat-conducting material 15 for covering the outer surface of the heat exchange tube group 19. The heat-conducting material 15 is graphene, which can be adapted to heat exchange tube groups 19 of different shapes to achieve the function of heating the heat exchange tube group 19 through graphene magnesium bricks.

[0081] In a further embodiment of the present invention, during the electromagnetic heating of the graphene magnesium bricks in the multiple first cavities at night, all the water in the water supply pipe 22 and the heat exchange tube group 19 is discharged to reduce heat transfer and heat loss in the shell 2.

[0082] In a further embodiment of the present invention, the control system adopts a field bus control system (FCS) and a programmable logic controller (PLC), and can be remotely controlled by a mobile phone app or other networked control system. By assembling different sensors or external sensing devices, the control system can realize temperature control and power control of the equipment, monitor the temperature changes of the graphene composite material and the pressure of the storage tank, the steam temperature and pressure, the water consumption and the steam volume, realize pressure safety control, short circuit safety control, and adjust the electrothermal conversion efficiency and the utilization rate of the stored thermal energy.
