Description

Technical Field

[0001] This utility model relates to the technical field of energy storage equipment, and in particular to a new energy graphene electric thermal energy storage equipment vehicle. Background Technology

[0002] With the increasing 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 generated by power plants at night. We know that power plants generate electricity during the day and their equipment continues to operate at night. This is because a 200,000-kilowatt generator unit takes about 10 hours to go from its rated power operating state to complete shutdown. In other words, the power plant's generating equipment hasn't stopped before the daytime demand for normal power generation returns. In cities, both factories and households consume very little electricity at night, and 70% of the electricity generated by power plants at night is unused waste electricity. Peak shaving and valley filling to increase nighttime electricity consumption is an effective measure for power grid energy conservation and emission reduction, and the most effective and feasible way to use electricity at night is through energy storage.

[0028] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies:

[0029] (1) This utility model is an electrothermal energy storage device based on graphene material. It utilizes the high thermal conductivity of graphene material and the high heat storage properties of aluminum or magnesium bricks. Through an electromagnetic coil wound 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 or more by electromagnetic attraction. The high temperature heat of the heat-resistant steel tank container shell is quickly conducted to the heat-conducting circuit type thermal energy storage composite material with magnesium bricks and graphene filling the gaps inside the heat-resistant steel tank container through the graphene powder with excellent thermal conductivity and heat resistance filling in the gaps inside the heat-resistant steel tank container. This achieves electrothermal energy conversion and storage, and finally achieves efficient and rapid thermal energy storage and release. Traditionally, magnesium brick energy storage can only be achieved by heating magnesium bricks with electric heating wires. The overall thermal conversion rate is generally only about 65% or even lower. Moreover, the electric heating wires (nickel-chromium alloy, iron-chromium alloy) will produce an oxidation reaction with high temperature, which reduces the electrothermal conversion rate and is more likely to produce cracks and fractures. The maintenance cost is high and basically equal to rebuilding. The electromagnetic heating method used in this invention achieves a heat conversion rate of up to 90%, offering significant advantages in energy saving and maintenance. Furthermore, traditional magnesium brick energy storage suffers from thermal stress and oxidation, making the bricks prone to breakage and surface peeling. This significantly reduces their heat storage and release capabilities after a period of use, necessitating replacement of broken bricks and repair of damaged heating wires, thus substantially increasing energy storage costs. This invention innovatively utilizes an indirect heat conduction energy storage method using magnesium bricks stacked with graphene as a filler. If a magnesium brick breaks during use or movement, the graphene powder will automatically fill the gaps created by gravity and human vibration, maintaining the original heat storage and release capacity of the magnesium brick. More importantly, the magnesium bricks used in this invention incorporate 1%-50% graphene powder during production, resulting in an extremely high melting point (approximately 3652°C) that remains stable even at high temperatures. Graphene is not easily deformed during heating, making it suitable for prolonged high-temperature use. It increases the strength and thermal conductivity of magnesium bricks and effectively prevents cracking and peeling of the outer layer under high-temperature conditions. Furthermore, graphene's excellent electrical conductivity effectively generates eddy currents, resulting in rapid heating of the magnesium bricks in an electromagnetic field. These innovative advantages of this invention are unattainable by traditional electric heating wire magnesium brick energy storage methods.

[0030] (2) When the electricity price is low at night, the electromagnetic heating system is activated. By precisely controlling the heating power and time, the thermal energy storage material is heated evenly to the saturated thermal storage state. When the vehicle is stationary or traveling to the energy transmission site during the day, the heat exchange unit starts to work and provides hot water or hot air as needed, or converts the thermal energy into electrical energy output through a steam turbine.

[0031] (3) In this utility model, electrical energy is successfully converted into thermal energy storage through the most energy-saving electromagnetic heating method. Graphene is used to realize high energy density energy storage and heat conduction technology, which 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 heat energy. It mainly relies on the electromagnetic field generated by a high-frequency AC power supply, which induces the free electrons inside the conductor of the heated object to vibrate and collide rapidly, thereby quickly converting the electrical energy in the conductor into heat energy.

[0046] Electromagnetic heating is based on Faraday's law of electromagnetic induction and Joule's law of heating. When a high-frequency power supply is applied, the resulting alternating current generates a changing magnetic field in the coil. This changing magnetic field passes through the conductor (usually metal) of the object being heated, causing the free electrons within the conductor to be acted upon by an induced force and begin to move at high speed. Due to the resistance between the free electrons within the conductor, their high-speed movement causes them to collide, and these collisions convert the electrons' kinetic energy into heat energy. In this way, electrical energy within the conductor is converted into heat energy, achieving the heating effect.

[0067] In a further embodiment of this invention, the invention significantly improves energy efficiency and reduces environmental pollution. In the future energy development blueprint, graphene-aluminum and graphene-magnesium brick energy storage technologies are expected to become a bridge connecting renewable energy sources and modern power grids. Developing a new energy storage method to participate in power system operation and better regulate the power generation function of electrical equipment is currently an urgent technical task. This invention is an electrothermal energy storage device based on graphene-aluminum or graphene-magnesium brick materials. Utilizing the high thermal conductivity of graphene and the high thermal storage properties of magnesium bricks, it achieves electrothermal conversion by electromagnetic heating of a heat-resistant steel tank, and uses graphene thermal conductivity to transfer the 600-degree heat from the surface of the heat-resistant steel tank into the internally stacked magnesium bricks for energy storage. This achieves efficient and rapid thermal energy storage and release. Compared to traditional thermal energy storage technologies, graphene-magnesium brick thermal energy storage materials have higher energy storage density and faster energy storage speed, capable of providing a large amount of thermal energy in a short time, meeting the needs of various application scenarios.

[0068] In a further embodiment of this invention, among current thermal energy storage materials, organic thermal energy storage materials have a maximum storage temperature of only around 300 degrees Celsius, while the graphene magnesium brick of this invention can store heat at temperatures exceeding 1000 degrees Celsius. Therefore, graphene magnesium brick is currently the most ideal thermal energy storage material. Magnesium brick has a specific heat capacity of 1.12 KJ / kg at 800 degrees Celsius. Among many metal materials with heat storage functions, aluminum has a melting point of 660 degrees Celsius 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 have specific heat capacities of only 0.39 KJ / kg, and lead is even worse. The specific heat capacities of these heat storage materials are all lower than those of magnesium brick. Based on the above data, graphene magnesium brick is the best thermal energy storage material. However, the main component of magnesium brick is magnesium oxide (MgO), which has very low electrical conductivity. Because magnesium bricks are non-conductive and have weak electromagnetic induction, they cannot be rapidly heated for energy storage using electromagnetic heating, which has the highest electrothermal conversion rate. Therefore, directly heating magnesium bricks via electromagnetic induction is not feasible. This is a key technical challenge hindering magnesium brick energy storage equipment. This invention utilizes the property of graphene, the fastest conducting material (graphene's thermal conductivity reaches 5104 W / m•K, far exceeding aluminum's 237 W / m•K, approximately 21 times that of aluminum; graphene's heat conversion rate is as high as 99.7%, with negligible heat loss during transfer). By leveraging graphene's excellent thermal conductivity, heat from the surface of the heat-resistant steel tank at 800 degrees Celsius is rapidly transferred to the magnesium bricks. This technology effectively solves the drawback of weak electromagnetic induction in magnesium bricks. This invention utilizes electromagnetic heating to rapidly heat a long, cylindrical, heat-resistant steel tank container with strong electromagnetic induction (tank diameter 1.2 meters; length 9 meters; tank wall thickness 3-30 mm; each 1.5 meters has a fully enclosed electromagnetic heating energy storage module unit; the entire device consists of 6 energy storage module units; between every two energy storage module units is a 0.3-meter-wide, 1.2-meter-diameter graphene-medium fully isolated binary heat exchange unit; the heat exchange unit and the energy storage module unit are two independent enclosed cavities, tightly connected). The energy storage unit of this 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 this utility model, 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 low electro-thermal conversion rate during electromagnetic heating due to its non-magnetic nature. At the same time, because the graphene is sintered inside the magnesium brick and does not come into contact with oxygen, the oxidation reaction that occurs during high-temperature energy storage is effectively avoided. It can quickly respond to external electromagnetic heating in a short time to convert power into energy and reach the required energy storage operating temperature.

[0070] In a further embodiment of this invention, the electromagnetic induction heating system is designed with a power of 200 kW per unit module; each equipment vehicle has 1-6 modules; the total power is 1200 kW, heating the thermal energy storage material to over 800 degrees Celsius in approximately 3-4 hours. The heat exchange unit of this invention employs a highly efficient and safe graphene-based fully isolated binary heat exchange technology. Because of the very strong covalent bonds between carbon atoms in graphene, electrons are freely transferred through these covalent bonds. This structure of graphene ensures high-speed electron conduction and also contributes to its high electrical and thermal conductivity. Graphene has extremely high thermal conductivity, with a thermal conductivity coefficient 13 times that of copper and 21 times that of aluminum, ensuring maximum thermal energy conversion efficiency of this equipment. The graphene-based fully isolated binary heat exchange technology of this invention guarantees the safety of this energy storage device during operation. The tank of this thermal energy storage device is made of 310S or 316Ti heat-resistant stainless steel, or other metals and materials such as ordinary iron plates and steel plates. This invention uses electromagnetic coils or thin copper tubes to heat the wall of a heat-resistant steel tank, which is highly susceptible to electromagnetic induction. Simultaneously, graphene filled between the magnesium bricks and between the magnesium bricks and the heat-resistant tank body rapidly introduces the 800°C high temperature generated by the electromagnetic interaction into the interior of the graphene-magnesium brick thermal energy storage material with minimal heat loss, allowing the magnesium bricks to store a large amount of heat energy. Furthermore, the graphene fired in the graphene-magnesium bricks can also effectively generate heat when electromagnetically heated in the heat-resistant steel tank using the power frequency 50Hz-1KHz (low frequency), which has the greatest electromagnetic penetration and heating depth. This invention efficiently converts electrical energy into stored heat energy through the most energy-efficient electromagnetic heating method, effectively overcoming the drawbacks of ordinary magnesium bricks' low thermal conductivity, which affects heat storage and release efficiency. This results in a high-energy-density graphene-magnesium brick energy storage composite material technology. In practical implementation, we convert the electrical energy from wind power, solar power, and waste electricity from 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 electrical energy is output through hot water, hot air, steam, or steam turbine power generation and cooling. Its rapid response capability and high-efficiency electrical / thermal energy conversion characteristics can balance the fluctuation drawbacks of solar and wind power generation and ensure the stable operation of the power grid. This utility model can be applied to more than 20 industries, including winter heating in residential areas or buildings, heating in bath centers, and wood drying, papermaking, printing, pharmaceuticals, chemicals, and textiles. The equipment can store 8,000 kWh of thermal energy each time, and nearly 3 million kWh of thermal energy per year, equivalent to saving about 1,000 tons of coal consumption from coal-fired power plants. The service life of this utility model equipment 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 sources, further promoting the healthy development of social progress.

[0071] In a further embodiment of this invention, the application of the graphene energy storage device may also be extended to the field of electric vehicles. With the increasing popularity of electric vehicles, the demand for efficient and fast charging technology is growing. 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 electrical resources through its efficient energy conversion capabilities. Compared with currently popular battery energy storage technologies, it has significant advantages in use. While battery energy storage is convenient and practical, its drawback is that its storage capacity decreases significantly after 3-5 years of use, requiring battery replacement at a huge cost, making it unprofitable. In contrast, the graphene magnesium brick thermal energy storage material of this invention has a lifespan of over 15 years, possessing a long service life advantage not found in other energy storage methods. It can optimize the energy structure, reduce dependence on high-carbon energy sources such as coal and oil, help reduce greenhouse gas emissions, and contribute to sustainable development.

[0072] In a further embodiment of this invention, the present invention is a high-performance energy storage and electrothermal conversion system. It utilizes electromagnetic heating technology to heat graphene-magnesium brick thermal energy storage material to a thermal energy storage state, with temperatures reaching approximately 800 degrees Celsius. This high-temperature state allows the material to store a large amount of thermal energy, which is then converted into hot water, hot gas, or used to drive a steam turbine for power generation through a heat exchange unit, achieving multiple energy outputs. This invention employs an intelligent, networked control system based on FCS and PLC, achieving automated control. Graphene, as a two-dimensional material with excellent mechanical, electrical, and thermal conductivity properties, plays an effective role in the development of new energy sources and smart grids. Graphene's single-atom-layer structure and numerous exposed chemical bonds enable rapid absorption of electromagnetic waves and heat conduction, overcoming the disadvantage of ordinary magnesium brick materials, which are non-magnetic and thus generate heat slowly when electromagnetically heated. Graphene-magnesium brick material is made by incorporating graphene into magnesium bricks, followed by sintering and solidification to obtain a composite thermal energy storage material. During energy storage, it utilizes inexpensive waste electricity from power plants at night to electromagnetically heat the graphene-magnesium bricks, causing them to absorb and store large amounts of heat energy within the thermal energy storage material. The energy can then be transported from the energy storage power source (factory, thermal power plant, wind power plant, solar power plant, or other inexpensive power source) to the energy consumption destination, either locally or by vehicle, to output hot gas, hot water, hot air, and gas turbine power generation. In summary, graphene energy storage equipment is a promising new energy device with broad application prospects. Its main functions include electromagnetic heating, automated control, and graphene-medium fully isolated binary heat exchange technology, enabling efficient, environmentally friendly, and safe energy output.

[0073] In a further embodiment of this utility model, the graphene energy storage device is specifically implemented as follows:

[0074] This invention includes the following steps: First, the graphene magnesium brick thermal energy storage material is loaded into a sealable heat-resistant steel tank, filling it to five-sixths full, leaving one-sixth of the space for thermal expansion and contraction. The tank is externally wrapped with a silicon-based heat-resistant insulation material with a heat resistance of over 2000 degrees Celsius to prevent heat loss. This ensures that after the equipment shuts down at saturation, the temperature of the graphene magnesium brick thermal energy storage material, which is around 600-1000 degrees Celsius, drops by approximately 15-20 degrees Celsius per hour. This 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 thermal saturation. When all the graphene magnesium brick thermal energy storage material reaches the preset thermal saturation state, the equipment stops working. During the day, when the equipment is stationary or traveling to an energy transmission location, the heat exchange unit begins operation, providing hot water or hot air as needed, or converting thermal energy into electrical energy output via a steam turbine.

[0075] The control system employs 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 information technology are another key feature of this invention. By integrating advanced communication modules, the energy storage vehicle can interconnect with a remote monitoring center in real time, uploading operational data and receiving dispatch instructions. The displays in the energy storage vehicle and the company's control center monitor the vehicle's location and operational status in real time based on information collected by various sensors and the BeiDou navigation and positioning system. Operators can remotely monitor the equipment's operating status via mobile phone or computer, performing fault diagnosis and maintenance intervention. In case of a crisis, an alarm will be promptly triggered for on-site personnel and remote monitoring personnel, urging on-site personnel to handle the fault immediately. Remote monitoring personnel can also remotely control the equipment for crisis intervention, achieving dual safety monitoring.

[0076] Graphene energy storage devices offer a novel solution for modern energy supply with their high-efficiency energy conversion capabilities, intelligent control and management systems, and convenient network information services. They have broad application prospects in various fields, including 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 this utility model, 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, at night, the electromagnetic coil 6 is energized by the power supply system. The electromagnetic coil is wound around the outside of multiple first cavities. The first cavity heats the heat-resistant steel tank container itself and the graphene magnesium bricks inside it through electromagnetic induction, realizing the function of energy storage, that is, electrical energy is converted into heat energy. During the day, the electromagnetic flow valve 20 and the electromagnetic water supply control valve 21 are opened. The control system monitors multiple intelligent pressure and level transmitters 3 in real time and controls the water level in multiple heat exchange tube groups 19. The heat energy stored in the graphene magnesium bricks in the first cavity heats the water in the heat exchange tube group 19 into water vapor, and then drives the generator set 1 to realize the power generation function.

[0079] In a further embodiment of this utility model, the outer surfaces of the multiple heat-resistant steel tank containers of the shell 2 are all covered with a heat-resistant insulation layer. The heat-resistant insulation layer is made of silicon-based heat-resistant insulation material, which does not affect the electromagnetic heating of the graphene magnesium bricks in the multiple first cavities by the electromagnetic coil 6, while improving the heat insulation performance of the heat-resistant steel tank containers and reducing the cooling rate of the graphene magnesium bricks.

[0080] In a further embodiment of this utility model, the interior of each of the multiple second cavities is filled with a thermally conductive material 15 for coating the outer surface of the heat exchange tube assembly 19. The thermally conductive material 15 is graphene, which can be adapted to heat exchange tube assemblies 19 of different shapes to achieve the function of heating the heat exchange tube assembly 19 through graphene magnesium bricks.

[0081] In a further embodiment of this utility model, 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 this utility model, the control system adopts a fieldbus control system (FCS) and a programmable logic controller (PLC), which can be remotely controlled by a mobile app or other networked control systems. By equipping different sensors or external sensing devices, the control system can realize temperature control, power control, monitoring of temperature changes of graphene composite materials and tank pressure, steam temperature and pressure, water consumption and steam volume, and can realize pressure safety control, short circuit safety control, and adjustment of electrothermal conversion efficiency and storage thermal energy utilization rate.
