Description

Technical Field

[0001] The present invention relates to the field of nuclear technology, and in particular to a road snow removal system based on nuclear energy. Background Art

[0002] Snow accumulation on roads in winter can make them slippery and increase the probability of traffic accidents. Existing de-icing and snowmelting technologies primarily rely on manual or mechanical snow removal, the application of de-icing agents, and methods that lower the freezing point. Due to the low efficiency of mechanical snow removal, de-icing agents are the most widely used and convenient de-icing method. However, with the widespread use of de-icing agents, their environmental impact has become increasingly apparent. Residual de-icing agents can severely abrade road surfaces. Ions in the de-icing agents chemically react with the alkaline aggregate in concrete, causing it to expand and crack, ultimately damaging the road surface. Furthermore, salt ions in the de-icing agents react with water to cause salt swelling, damaging the roadbed. Summary of the Invention

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment discloses a nuclear energy-based road snow removal system, which includes a first snow removal unit, the first snow removal unit including a phase change heat storage device 9 and a first snow melting pipe 14A, wherein:

[0029] The phase change heat storage device 9 is connected to the warm drainage system in the nuclear power plant. Phase change material is provided in the phase change heat storage device 9. The first snow melting pipe 14A is connected to the phase change heat storage device 9 and laid under the road. Snow removal medium (such as water) flows in the first snow melting pipe 14A.

[0030] Under non-snow removal conditions, the phase change material exchanges heat with the warm wastewater flowing through the phase change thermal storage device 14A, absorbing and storing the heat of the warm wastewater. The phase change temperature of the phase change material matches the temperature of the warm wastewater, and the phase change material changes from solid to liquid after absorbing the heat of the warm wastewater.

[0031] Under snow removal conditions, the snow removal medium in the first snow melting pipe 14A flows into the phase change heat storage device 9 and exchanges heat with the phase change material, absorbing the heat of the phase change material. Afterwards, it returns from the inlet end of the first snow melting pipe 14A, melts the snow on the road after heat exchange with the road, and achieves snow removal.

[0032] Specifically, if Figure 1As shown, in a nuclear power plant, the steam generator 2 absorbs the heat generated by the reactor 1 to generate a large amount of steam, which enters the steam turbine 3 to perform external work. The steam after performing the work is the turbine exhaust steam. The warm drainage system includes a condenser 4, a water inlet pipe 21, and a water delivery pipe 22. The condenser 4 includes a first pipeline and a second pipeline, wherein: the inlet of the first pipeline is connected to the gas outlet of the turbine 3 for introducing turbine exhaust steam; the inlet of the second pipeline is connected to the water inlet pipe 21 for introducing water (such as seawater). The water exchanges heat with the turbine exhaust steam in the first pipeline in the second pipeline to increase its temperature to produce warm drainage. After heat exchange, the turbine exhaust steam is cooled and condensed to obtain condensed water; the outlet of the second pipeline is connected to the water delivery pipe 22 for transporting the produced warm drainage. The phase change heat storage device 9 is connected to the water delivery pipe 22, so as to introduce warm drainage and exchange heat with the phase change material. A first pump 10 is provided on the water delivery pipe 22 for transporting warm drainage; the outlet of the first pipeline is connected to the steam generator 2 for transporting the condensed water after heat exchange back to the steam generator 2 for recycling.

[0033] In this embodiment, the condenser 4 may be a shell and tube heat exchanger, the first pipeline is preferably a shell side, and the second pipeline is preferably a tube side.

[0034] In some embodiments, the first snow removal unit also includes a heat pump device, which is respectively connected to the phase change heat storage device 9 and the first snow melting pipe 14A. Refrigerant flows in the heat pump device. The heat pump device is used to use the refrigerant to absorb the heat of the warm drainage flowing out of the phase change heat storage device 9 and transfer the heat to the snow removal medium flowing out of the phase change heat storage device 9.

[0035] Specifically, the heat pump device includes a compressor 5, a condenser 6, and an evaporator 8, wherein: the compressor 5, the condenser 6, and the evaporator 8 are sequentially connected through pipes to form a closed loop, and the refrigerant is arranged in the closed loop; the evaporator 8 is connected to the phase change heat storage device 9, which is used to pass the warm drainage water flowing out of the phase change heat storage device and exchange heat with the refrigerant in the evaporator 8, so that the refrigerant absorbs heat and heats up. The refrigerant after absorbing heat is compressed by the compressor 5 and flows into the condenser. The warm drainage water after heat exchange is discharged through the drain pipe 23 (such as into the sea); the pipe side of the condenser 6 is connected to the phase change heat storage device 9, The inlet ends of the first snow-melting pipe 14A are respectively connected to form a circulation loop for introducing the snow-removing medium flowing out of the phase-change heat storage device, and further heating it by exchanging heat with the heated refrigerant in the condenser 6, and returning the further heated snow-removing medium from the inlet end of the first snow-removing pipe 14A to the first snow-removing pipe 14A, thereby realizing the recycling of the snow-removing medium. That is, the phase-change heat storage device 9 is equivalent to being used to preheat the snow-removing medium flowing out of the first snow-melting pipe 14A, and the condenser 6 is used to further heat the preheated snow-removing medium by using the refrigerant that has absorbed heat and heated up.

[0036] Furthermore, the heat pump device further comprises a throttle valve 7, which is provided on the closed loop and is located upstream of the evaporator 8 and downstream of the condenser 6, for throttling and reducing the pressure of the high-pressure refrigerant.

[0037] In some embodiments, the system further includes a bypass pipe, which is arranged in parallel with the evaporator 8. The bypass pipe's inlet end is connected to the phase-change heat storage device 9, and its outlet end is connected to the drain pipe 23 (i.e., the downstream section of the water supply pipe). The bypass pipe is provided with a first control valve 11, which controls the opening and closing of the bypass pipe. During non-snow removal operations, the first control valve 11 is generally open, and the warm wastewater is preferentially discharged into the sea through the bypass pipe. During snow removal operations, the first control valve 11 is closed, allowing the warm wastewater to flow through the evaporator 8, exchanging heat with the refrigerant, further absorbing the warm wastewater's heat. After absorbing the heat, the refrigerant exchanges heat with the snow removal medium in the condenser 6, further heating the snow removal medium.

[0038] In this embodiment, the first control valve 11 is preferably a solenoid valve.

[0039] In some embodiments, the system further includes a second pump 13 , which is disposed on the first snow melting pipe 14A and is used to transport snow removal medium to speed up the circulation of the snow removal medium and improve snow removal efficiency.

[0040] In this embodiment, the second pump 13 is preferably provided at the inlet end of the first snow melting pipe 14A, and the heated snow removal medium is pumped back into the first snow melting pipe 14A through the second pump 13 .

[0041] In some embodiments, the system further includes a first monitoring and control device 12, which is connected to the compressor 5 and the second pump 13 respectively, for monitoring the road environment and controlling the compressor 5 and the second pump 13 to start when snow is detected.

[0042] In this embodiment, the first monitoring and control device 12 specifically includes a first temperature and humidity sensor, a first camera mechanism, and a first controller. The first temperature and humidity sensor and the first camera are both electrically connected to the first controller. The first temperature and humidity sensor is used to monitor the road surface temperature and humidity in real time and transmit them to the first controller. The first camera mechanism is used to monitor the road surface condition in real time and send a snowing signal to the first controller when snowing is detected. The first controller is electrically connected to the compressor 5 and the second pump 13 respectively. The first temperature threshold and the first humidity threshold are preset in the first controller, which is used to receive the temperature value and humidity value detected by the first temperature and humidity sensor and control the compressor 5 and the second pump 13 to start snow removal when the temperature value is less than the first temperature threshold, the humidity value is greater than the first humidity threshold, and when a snowing signal is received.

[0043] It should be noted that the first monitoring and control device 12 can also be connected to the first control valve 11, and is used to control the compressor 5 and the second pump 13 to start and control the first control valve 11 to close when snow is detected.

[0044] In some embodiments, the first snow melting pipe 14A is laid in an S-shape along the length of the road.

[0045] In some embodiments, aluminum foil 15 is provided between the first snow melting pipe 14A and the road to enhance heat transfer.

[0046] Specifically, the road is preferably a highway paved with asphalt, and the first snow melting pipe 14A is laid under the asphalt. The aluminum foil 15 is provided between the first snow melting pipe 14A and the asphalt.

[0047] The snow removal process of the nuclear energy-based road snow removal system of this embodiment is described in detail below.

[0048] When it snows, the compressor 5 and the second pump 13 are turned on, and the first control valve 11 is closed. The warm drainage water is first passed into the phase change heat storage device 9 to preheat the snow removal medium flowing out of the first snow melting pipe 14A, and then the warm drainage water flowing out of the phase change heat storage device 9 is passed into the evaporator 8. The refrigerant absorbs the heat of the warm drainage water and exchanges heat with the snow removal medium flowing out of the phase change heat storage device 8, so that the snow removal medium is further heated and the temperature of the snow removal medium is produced to produce a snow removal medium with a higher temperature. After that, the medium is returned to the first snow melting pipe 14A under the road, thereby melting the snow on the road.

[0049] The nuclear energy-based road snow removal system of this embodiment fully utilizes the waste heat from nuclear power plant warm wastewater for snow removal. Compared to traditional technologies, it offers high snow removal efficiency, is convenient, energy-efficient, and environmentally friendly, without damaging roads. It also reduces the temperature of nuclear power plant warm wastewater, mitigating the impact of direct discharge into the sea on marine ecosystems. Furthermore, by incorporating a phase-change thermal storage device, heat can be stored during non-snow removal operations, improving energy utilization and broadening the scope of nuclear energy comprehensive utilization. By incorporating a heat pump device, nuclear energy can be utilized in a gradient manner in conjunction with the phase-change thermal storage device, raising the temperature of the snow removal medium, enhancing snow removal efficiency, and improving energy utilization. The provision of a first monitoring and control device enables automatic control, providing convenient and intelligent functionality.

[0050] Example 2

[0051] like Figure 2 As shown, this embodiment discloses a nuclear energy-based road snow removal system, which includes a second snow removal unit. The second snow removal unit includes a second snow melting pipe 14B. The second snow melting pipe 14A is connected to the nuclear energy heating network and laid under the road for passing the heating medium in the nuclear energy heating network to remove snow. That is to say, this system directly uses the heat of the nuclear energy heating network to remove snow from the road.

[0052] Specifically, if Figure 2 As shown, in a nuclear power plant, the steam generator 2 absorbs the heat generated by the reactor 2 to generate a large amount of steam. The steam enters the steam turbine 3 to perform external work. The steam turbine 3 is provided with a steam extraction port, which is preferably located at the middle stage of the steam turbine. A portion of the steam extracted from the steam extraction port is the steam turbine extraction steam. The nuclear energy heating network includes a nuclear power plant heat exchanger 16, a thermal power station heat exchanger 17, a circulation pipe 24, and a heating pipe 25. The nuclear power plant heat exchanger 16 is connected to the steam extraction port of the steam turbine 3 in the nuclear power plant. The thermal power station heat exchanger 17 is connected to the nuclear power plant heat exchanger 16 through the circulation pipe 24. The inlet end of the second snow melting pipe 14B is connected to the thermal power station heat exchanger 17 through the heating pipe 25. A circulating medium (such as water) flows through the circulation pipe 24. The heating pipe 25 is used to circulate the heating medium (such as heating water). The nuclear power plant heat exchanger 16 is used to pass the steam turbine. Steam is extracted and heat-exchanged with the circulating medium, causing the circulating medium to absorb heat from the turbine extraction steam and rise in temperature. The turbine extraction steam then cools and condenses after heat exchange, producing condensate. The nuclear power plant's post-heat exchanger 16 is also connected to the steam generator 2, transporting the resulting condensate back to the steam generator 2 for recycling. The thermal power station heat exchanger 17 is used to introduce the heated circulating medium and exchange heat with the medium in the heating pipe 25, transferring heat to the medium in the heating pipe 25 to produce the heating medium. The heating medium is then introduced into the second snow-melting pipe 14B for snow removal. The outlet of the second snow-melting pipe 14B is also connected to the thermal power station heat exchanger 17, transporting the cooled heating medium back to the thermal power station heat exchanger 17 for recycling. A second control valve 20 is provided at the inlet end of the second snow-melting pipe 14B. Under snow-removal conditions, the second control valve 20 is in an open state, the snow-melting mode is turned on for snow removal, and a portion of the heating medium is passed from the heating pipe into the second snow-removal pipe 14B; under non-snow-removal conditions, the second control valve 20 is generally in a closed state.

[0053] In this embodiment, the second control valve 20 is preferably a solenoid valve.

[0054] In some embodiments, the system further includes a third pump 19 , which is provided on the second snow melting pipe 14B and is used to transport the heating medium to speed up the circulation of the heating medium and improve the snow removal efficiency.

[0055] In this embodiment, the third pump 19 is preferably provided at the inlet end of the second snow melting pipe 14B, and the heating medium in the heating pipe 25 is pumped into the second snow melting pipe 14B by the third pump 19 for snow removal.

[0056] In some embodiments, the system further includes a second monitoring and control device 18 , which is connected to a third pump 19 and is configured to monitor the road environment and control the third pump 19 to start when snow is detected.

[0057] In this embodiment, the second monitoring and control device 18 specifically includes a second temperature and humidity sensor, a second camera mechanism, and a second controller. The second temperature and humidity sensor and the second camera are both electrically connected to the second controller. The second temperature and humidity sensor is used to monitor the road surface temperature and humidity in real time and transmit them to the second controller. The second camera mechanism is used to monitor the road surface condition in real time and send a snowing signal to the second controller when snowing is detected. The second controller is electrically connected to the third pump 19. The second controller has a second temperature threshold and a second humidity threshold preset in it, which is used to receive the temperature and humidity values ​​detected by the second temperature and humidity sensor and control the third pump 19 to start snow removal when the temperature value is less than the second temperature threshold, the humidity value is greater than the second humidity threshold, and a snowing signal is received.

[0058] In some embodiments, the second snow melting pipe 14B is laid in an S-shape along the length of the road.

[0059] In some embodiments, aluminum foil 15 is provided between the second snow melting pipe 14B and the road to enhance heat transfer.

[0060] Specifically, the road is preferably a highway paved with asphalt, and the second snow melting pipe 14B is laid under the asphalt. The aluminum foil 15 is provided between the second snow melting pipe 14B and the asphalt.

[0061] The snow removal process of the nuclear-powered road snow removal system is described in detail below:

[0062] The second control valve 20 and the third pump 19 are opened to allow the heating medium to flow into the second snow removal pipe 14B. When the heating medium flows through the second snow melting pipe 14B under the road, the snow on the road is melted.

[0063] The nuclear-powered road snow removal system of this embodiment has a simple structure and can directly utilize the heating medium in the nuclear-powered heating network to remove snow. Compared with traditional technologies, it is highly efficient, convenient, energy-efficient, environmentally friendly, and does not damage roads. Furthermore, by providing a second monitoring and control device, it can achieve automatic control, making it convenient and intelligent.

The specific structures of the first snow removal unit and the second snow removal unit are not described in detail in this embodiment.

[0066] It should be noted that the first temperature threshold and the first humidity threshold preset in the first controller may be the same as or different from the second temperature threshold and the second humidity threshold preset in the second controller. Furthermore, the first monitoring and control device 12 and the second monitoring and control device 18 may be combined into a single monitoring and control device. In this case, the monitoring and control device is simultaneously connected to the compressor 5, the first pump 10, the second pump 13, and the third pump 19, respectively, and has all the functions of the first monitoring and control device 12 and the second control device 13.
