Description

Technical Field

[0001] The present invention relates to the field of electric power engineering technology, and in particular to a method and system for mobile zero-emission heating based on a new energy source. Background Art

[0002] Urban heating, as an important part of urban infrastructure, not only involves energy supply and management, but also affects the quality of life of residents and the sustainable development of the city. How to effectively reduce greenhouse gas emissions, promote green and low-carbon development, and protect blue skies and white clouds to the greatest extent while meeting residents' heating and industrial heat needs is the key to achieving sustainable development.

[0003] From a technical perspective, greenhouse gas emissions can be divided into two categories: direct emissions and indirect emissions:

[0004] Regarding direct greenhouse gas emissions, the company has implemented a series of practical measures. For example, traditional fossil fuel equipment has been replaced with electric-powered equipment, replacing coal, oil, and other fossil fuels with electricity in the production process, thereby reducing direct emissions of greenhouse gases such as carbon dioxide. Regarding firefighting equipment, products that may generate greenhouse gas emissions, such as dry powder fire extinguishers, have been replaced with environmentally friendly, non-CO2-filled fire extinguishers, reducing direct emissions at the source.

[0005] When it comes to indirect greenhouse gas emissions, companies are focusing on emissions from purchased electricity. By purchasing green electricity, such as wind power, photovoltaic power, and other clean energy sources, to replace traditional thermal power generation, they effectively reduce indirect greenhouse gas emissions from electricity consumption. However, companies face significant challenges when it comes to purchasing steam. Currently, there is virtually no zero-emission green steam available on the market, making it difficult for companies to achieve a zero-carbon steam supply.

[0006] There are two main methods for supplying steam to enterprises: using boilers to produce steam, and using pipelines to generate steam. Both methods rely on fossil fuels such as coal and natural gas to produce steam. When calculating emissions from steam use, emissions from the raw materials used to produce steam must be fully considered, making steam supply a crucial component of an enterprise's emissions.

[0007] To achieve zero-emission steam supply, the company considered purchasing high-power electric boilers to produce steam. However, this approach faced numerous practical difficulties. High electricity costs were a primary concern for the company. These costs included not only the basic electricity cost but also the nominal transformer costs. These nominal transformer costs refer to the additional fees charged by the power company due to factors such as substandard power factor. These combined costs made steam production with electric boilers significantly more expensive than with traditional fossil fuel boilers, making it financially unaffordable for the company. Therefore, considering the overall cost-benefit ratio, companies generally avoided using high-power electric boilers.

[0008] In recent years, my country's renewable energy power generation industry has achieved remarkable development, with numerous centralized photovoltaic, wind, and distributed photovoltaic power generation projects coming online. However, renewable energy generation is intermittent and unstable, significantly affected by weather conditions. For example, photovoltaic power generation is ineffective at night, while wind power generation capacity depends on wind speed. This instability poses significant challenges to the stable operation of the power grid, preventing some renewable energy power from being consumed in a timely manner, leading to power curtailment and a waste of social resources.

[0009] At the same time, businesses' demand for steam remains stable and continuous. Steam plays a vital role in production processes, such as heating, drying, and disinfection. Accurately matching businesses' steam demand with the curtailment of renewable energy generation would not only solve the challenge of achieving zero-emission steam supply, but also effectively reduce curtailment and optimize resource allocation.

[0010] Therefore, how to accurately match the steam demand of enterprises with the power abandonment of new energy power generation and achieve zero emissions in steam supply has become an urgent problem to be solved. Summary of the Invention

[0034] Figure 2 This is a schematic diagram of a mobile zero-emission heating system based on a new energy source in a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.

[0036] In a preferred embodiment of the present invention, based on the above problems existing in the prior art, a mobile zero-emission heating method based on a new energy source is provided, such as Figure 1 and Figure 2 As shown, including:

[0037] Step S1: Connecting a mobile heat storage device to a photovoltaic power generation module to convert the electrical energy generated by the photovoltaic power generation module into thermal energy and store it;

[0038] The photovoltaic power generation module includes photovoltaic modules and mobile energy storage devices connected in sequence. The photovoltaic modules use solar panels to convert solar energy into electrical energy. The mobile energy storage device is used to obtain and store the electrical energy generated by the photovoltaic modules, thereby powering the mobile thermal storage device.

[0039] Step S2: After the mobile heat storage device completes the storage of heat energy, the mobile heat storage device is transported to the location of the target requiring heat supply using a new energy transportation device as a transport carrier;

[0040] Step S3: After the mobile heat storage device arrives at the location of the target requiring heat supply, the mobile heat storage device is connected to cold water so that the mobile heat storage device converts the stored heat energy into steam under the action of the cold water, thereby achieving zero-emission heat supply to the target requiring heat supply.

[0041] Specifically, in this embodiment, a clean energy solution is provided that takes photovoltaic power generation as the starting point, realizes energy storage through efficient heat storage technology, and ultimately meets user needs through a smart heating system. Its core is to break the linear model of traditional energy "generation-transmission-distribution-use". Through the coordinated operation of the four major links of photovoltaic power generation, thermal energy storage, smart transportation and efficient heating, a complete energy chain of "light-heat-use" is constructed, realizing a green closed loop from energy production to application. This system not only solves the problem of clean heating in remote areas (such as islands and pastoral areas), reduces the environmental pressure brought by coal transportation, but also provides innovative solutions for scenarios such as industrial waste heat recovery and emergency heating. It is a key technical path to promote the zero-carbon transformation of the energy system. The overall impact on the local environment is controllable and has significant environmental benefits.

[0042] In a preferred embodiment of the present invention, an external power supply is further included, which is connected to the photovoltaic module and the mobile energy storage device respectively. The electric energy generated by the photovoltaic module is transmitted to the mobile energy storage device through the external power supply for storage.

[0043] Specifically, in this embodiment, the photovoltaic power generation module 1 is used to generate electricity using solar energy through the photovoltaic components 11. It can continuously generate electricity under conditions of sufficient sunlight, ensuring that the system can efficiently store and manage energy.

[0044] The mobile energy storage device 12 is preferably connected to an external power source, which can be a charge controller. The solar panels used in the photovoltaic module 11 convert solar energy into direct current (DC), and their output voltage and current are affected by light intensity and temperature. The electrical energy generated by the photovoltaic module can be transmitted to the mobile energy storage device for storage via the charge controller. The charge controller is a core component responsible for regulating voltage and current to protect the mobile energy storage device from damage caused by overcharging / over-discharging. Specifically:

[0045] The charge controller can adjust the load impedance in real time to ensure that the solar panel always operates at the maximum power point and improve the energy conversion efficiency.

[0046] The charge controller reduces the output voltage of the solar panel to an acceptable charging voltage for the mobile energy storage device and limits the current to match the battery capacity.

[0047] The charge controller provides protection against overcharge, overdischarge, short circuit and reverse current.

[0048] Preferably, the mobile energy storage device includes, but is not limited to, a lithium battery pack that can directly receive direct current (DC) power. Specifically, the DC power output by the solar panels is directly input into the mobile energy storage device via a charge controller. The mobile energy storage device is preferably also equipped with a battery management system to further monitor the status of individual batteries and ensure safe charging.

[0049] In special circumstances, such as when the mobile energy storage device is a UPS system, AC charging is required. The external power supply preferably also includes an inverter, which is connected to the charge controller and the mobile energy storage device respectively. That is, an inverter is added after the charge controller to convert the DC power output by the solar panel into AC power, and provide AC power to the mobile energy storage device through the charge controller for charging.

[0050] As a preferred embodiment, if the mobile energy storage device itself has a built-in MPPT module, that is, it can achieve maximum power point tracking. In other words, it can adjust the load impedance in real time to ensure that the solar panel always operates at the maximum power point. In this case, the charge controller does not need to have this function. In this case, the charge controller can be simplified to a voltage regulator.

[0051] In a preferred embodiment of the present invention, the mobile heat storage device 2 includes an electric heater 21 and a molten salt energy storage device 22. The electric heater 21 is electrically connected to the molten salt energy storage device 22 and the mobile energy storage device, respectively, and is used to supply power through the mobile energy storage device to heat the molten salt energy storage device 22.

[0052] Specifically, in this embodiment, using molten salt energy storage has the following advantages:

[0053] 1. High specific heat capacity: Molten salt has a high specific heat capacity characteristic, which can store a large amount of thermal energy in a small volume, thereby improving the energy storage density.

[0054] 2. Wide operating temperature range: The operating temperature range of molten salt is relatively wide, which is highly compatible with the characteristics of photovoltaic power generation. It can be adjusted according to actual needs to adapt to different application scenarios.

[0055] 3. Good chemical stability: Molten salt has good chemical stability at high temperatures and is not easy to decompose or corrode equipment, thus extending the service life of the equipment.

[0056] 4. Low cost and environmental protection: Molten salt materials are widely available and low in cost. They do not produce harmful substances during the heat storage and release process, thus meeting environmental protection requirements.

[0057] As a preferred embodiment, the molten salt energy storage device 22 is the core component of the system. Its design should fully consider the characteristics of the molten salt and the heat storage requirements. It is preferably made of high-temperature corrosion-resistant materials, such as stainless steel, nickel-based alloys, etc., to ensure that no leakage or temperature drop occurs during the heat storage process. At the same time, the molten salt energy storage device 22 should have good thermal insulation performance to reduce heat loss.

[0058] As a preferred embodiment, the molten salt energy storage device 22 can be equipped with an intelligent temperature control system. This intelligent temperature control system uses temperature sensors, pressure sensors, and other sensors to monitor the temperature, pressure, and phase change state of the molten salt in real time and transmits this data to a control system. Based on this monitoring data, the control system automatically adjusts the heating power of the electric heater and the flow rate of the molten salt to achieve precise control of the molten salt temperature. Furthermore, the intelligent temperature control system also has fault warning and alarm functions. When the monitoring data exceeds the set range, it promptly issues an alarm, prompting the operator to take appropriate measures to ensure the safety and stability of the heat storage process.

[0059] In a preferred embodiment of the present invention, the electric heater 21 is an electric heating tube or an electric heating film, which has the functions of rapid heating and precise temperature control.

[0060] Specifically, in this embodiment, electric heater 21 is a key device for converting electrical energy into thermal energy. Its performance directly impacts the system's heat storage efficiency. Therefore, electric heater 21 should be made of high-efficiency, high-temperature-resistant materials, such as nickel-chromium alloy or tungsten, to improve heating efficiency and service life. Furthermore, electric heater 21 should be equipped with an intelligent control system that automatically adjusts heating power based on the molten salt temperature and heat storage requirements, achieving precise temperature control.

[0061] After the mobile heat storage device completes the heat storage node, the next step is to use new energy transportation equipment 3 to accurately transport the mobile heat storage device 2 to the location of the target that needs heat, so as to achieve efficient transportation and supply of heat storage molten salt.

[0062] The above-mentioned new energy transportation equipment 3 includes but is not limited to new energy vehicles, such as pure electric vehicles or hydrogen fuel cell vehicles or other zero-emission vehicles, to ensure zero carbon emissions during transportation. The primary consideration in selecting new energy transportation equipment 3 as a transportation carrier for heat storage equipment is its zero-carbon emission characteristics. In traditional transportation methods, the exhaust gas emitted by fuel vehicles contains a large amount of greenhouse gases and pollutants, which cause serious damage to the atmospheric environment and aggravate global climate change. New energy transportation equipment, with its clean energy power system, eliminates carbon emissions at the source, providing solid support for the greening and low-carbonization of the transportation link. This is not only in line with the current global trend of energy conservation and emission reduction, but also an inevitable requirement for responding to climate change and promoting sustainable development.

[0063] In addition to its environmental advantages, the new energy transportation equipment 3 also needs to have sufficient load-bearing capacity to transport the molten salt energy storage device 22. As the core component of the mobile heat storage device 2, the molten salt energy storage device 22 is relatively large in size and weight. This requires the transportation equipment to have strong load-bearing performance while ensuring zero carbon emissions, thereby ensuring safety and stability during transportation and avoiding transportation accidents or equipment damage due to insufficient load.

[0064] As a specialized energy storage medium, molten salt's ability to retain heat is crucial for subsequent heating effectiveness. During long-distance transportation, factors such as ambient temperature fluctuations and bumps during transportation can cause the molten salt's heat energy to dissipate. However, an efficient temperature control system, through real-time monitoring and precise regulation, maintains a suitable temperature environment within the container, ensuring that the heat energy within the molten salt energy storage device remains stable. When the transport vehicle arrives at its destination, the heat energy within the molten salt energy storage device is still effectively providing heating needs, providing continuous and stable heat to the site in need.

[0065] To achieve the above objectives, it is more preferred that the container of the new energy transport equipment 3 is equipped with an efficient temperature control system, which uses advanced sensor technology, intelligent control algorithms and efficient thermal insulation materials. The sensor can sense the temperature changes in the container in real time and transmit the data to the intelligent control system. The intelligent control system automatically adjusts the operating status of the temperature control equipment according to the preset temperature range and real-time data, such as the adjustment of cooling or heating power. At the same time, the efficient thermal insulation material can effectively reduce the exchange of heat with the external environment, further reducing heat energy loss. This multi-technology integrated temperature control system not only improves the ability to retain heat energy during transportation, but also provides a strong guarantee for the widespread application of mobile heat storage equipment.

[0066] As can be seen, using new energy transportation equipment 3 to transport mobile thermal storage equipment 2 not only solves energy transportation and supply issues but also opens up a new path for the green transformation of the energy industry. It promotes the deep integration of new energy technologies in transportation and energy storage, and promotes the coordinated development of related industrial chains. With continuous technological advancement and gradual cost reduction, this green and efficient energy transportation and supply model is expected to be promoted and applied in more fields, contributing to the sustainable development of global energy.

[0067] In a preferred embodiment of the present invention, the mobile heat storage device 2 also includes a heat exchange system 23, which is connected to the molten salt energy storage device 22 and has a cold water interface 231 and a steam outlet 232, and is used to connect cold water through the cold water interface 231 and then transport it to the molten salt energy storage device 22 for heat exchange, and output the generated steam through the steam outlet 232.

[0068] Specifically, in this embodiment, the heat exchange system is responsible for transferring the thermal energy stored in the molten salt to the working medium. By configuring the heat exchange system in the mobile energy storage device, heat exchange between the molten salt and the flow of external cold water is achieved, thereby enabling efficient steam output for use by equipment or facilities that require steam.

[0069] When the mobile heat storage device 2 is in operation, external cold water enters the heat exchange area of the heat exchange system 23 through the cold water interface 231 and can directly or indirectly exchange heat with the molten salt in the molten salt energy storage device 22 .

[0070] In direct heat exchange, cold water and molten salt come into direct contact via a specific heat exchange surface, preferably one with excellent thermal conductivity and a large effective contact area, ensuring efficient heat transfer. When the cold water and molten salt come into contact, the high-temperature heat contained in the molten salt is quickly and directly transferred to the cold water, causing the cold water molecules to move violently and the temperature to rise sharply. This method offers significant advantages such as high heat exchange efficiency and minimal heat loss, enabling rapid transfer of large amounts of heat in a short period of time.

[0071] In indirect heat exchange, shell and tube or plate heat exchangers are usually used. Among them, the shell and tube heat exchanger is a complex structure composed of many slender pipes and a shell. The cold water flows in an orderly manner in the pipes, and the molten salt flows in the opposite direction in the space between the pipes and the shell. The plate heat exchanger is composed of a series of parallel metal plates. The cold water and molten salt shuttle in opposite directions in the adjacent plate channels. Although the two are not in direct contact, a tight heat transfer bridge is established through the metal wall of the heat exchanger. The metal wall acts as an efficient heat conduction medium, quickly transferring the heat in the molten salt to the cold water, causing the cold water temperature to gradually increase, while the molten salt gradually decreases in temperature during the heat release process, completing the heat transfer cycle.

[0072] After sufficient heat exchange, the cold water is heated to high-temperature steam and discharged from the steam outlet. This steam contains rich thermal energy and can be widely used in various fields such as industrial production, heating, and power generation.

[0073] For example, in industrial production, mobile thermal storage equipment equipped with heat exchange systems can be flexibly transported to different factories based on actual production needs, providing a stable and reliable steam supply. This not only reduces energy procurement costs for enterprises, but also increases the flexibility and autonomy of energy supply, helping enterprises achieve energy conservation, emission reduction, and sustainable development goals.

[0074] In the heating sector, mobile thermal storage devices can store heat energy in advance and, when heating is needed, output steam through a heat exchange system to provide warmth to areas or buildings. Furthermore, because they utilize clean energy as their power source, they produce virtually no pollutants during operation, meeting environmental requirements and playing a significant role in improving environmental quality and promoting clean heating.

[0075] In special scenarios like emergency rescue and field operations, power outages can disrupt traditional heating equipment. Mobile thermal storage equipment, with its independent operation, can be quickly deployed on-site to provide hot water, steam, and other energy support to rescuers and construction workers, ensuring the smooth progress of rescue and construction work.

[0076] In addition, after the heat exchange system completes the critical step of heat release, the molten salt can also be monitored for its status, such as real-time monitoring and analysis of key parameters such as flow rate, temperature, and chemical composition. If all parameters meet the requirements of compound recycling, it can be transported back to the photovoltaic power generation module for a new round of heating and utilization. The molten salt will once again absorb the heat provided by the external heat source and store a large amount of thermal energy, waiting for the next heat release and utilization. And so on. This recycling mechanism not only significantly improves energy utilization efficiency and reduces energy waste, but also reduces equipment operating costs.

[0077] In summary, the present invention realizes mobile zero-emission heating based on new energy through the coordinated work of photovoltaic power generation modules, mobile heat storage equipment, and new energy transportation equipment. It can achieve efficient conversion of light storage and heat without carbon emissions. By transporting the stored heat energy to the location where heating is needed by new energy vehicles, the carbon emission problems caused by traditional coal-fired or gas-fired heating systems are avoided. Finally, the stored heat energy is converted into steam through an efficient heat exchange system to meet the heating needs of different locations of the enterprise, filling the gap in the market, and has significant environmental protection, energy saving and economic benefits.

[0082] The mobile heat storage device 2 is also used to convert the stored heat energy into steam by accessing cold water at the location of the target requiring heat, thereby achieving zero-emission heat supply to the target requiring heat.
