Description

Technical Field

[0001] The present invention relates to the technical field of solar thermal power generation, and in particular to a photothermal power generation device with high efficiency heat exchange. Background Art

[0002] In the field of solar thermal power generation technology, traditional solar thermal power generation devices generally have problems such as low light energy utilization, insufficient heat exchange efficiency and poor system stability, which restrict their large-scale application and economic improvement.

[0003] On the one hand, traditional CSP systems often use fixed-angle or single-axis tracking reflectors, which cannot accurately track the sun's position. This results in a significant decrease in solar energy capture efficiency in the morning, evening, and during cloudy weather. Furthermore, the loose layout of the reflector array prevents the formation of a high-density focusing area, resulting in unstable heat input to the heat absorption mechanism. Furthermore, the reflector surface is prone to dust accumulation and is affected by environmental factors, further reducing reflectivity. Traditional cleaning methods are time-consuming and water-intensive, making it difficult to maintain long-term efficient operation.

[0004] On the other hand, existing heat exchange structures mostly adopt a simple shell and tube design, with limited heat transfer area and uneven flow field distribution. In traditional solar thermal systems, the hot fluid pipeline only transfers heat through the light tube, and the cold fluid easily forms a flow dead zone in the heat exchange tank. At the same time, there is a lack of optimized design of the cold fluid flow field. The high-speed airflow directly impacts the hot pipeline, causing local overheating and energy loss, and the energy of the high-temperature heat source cannot be fully utilized.

[0005] Furthermore, traditional devices lack coordinated control over the focusing, heat absorption, and heat exchange processes. The mismatch between reflector angle adjustment and the heat absorption mechanism's thermal load can easily lead to overheating of the absorber tubes or large temperature fluctuations in the thermal fluid. Furthermore, existing systems rely on manually set operating parameters and are unable to dynamically adjust to real-time light intensity, ambient temperature, and other factors. This can lead to delayed system responses during sudden weather changes or the alternation of day and night, potentially causing equipment failure or downtime, severely impacting power generation stability and energy efficiency.

[0006] In view of this, an object of the present invention is to provide a photothermal power generation device with high efficiency heat exchange to solve the deficiencies in the prior art. Summary of the Invention

[0034] Specifically, the heat absorption component in the heat absorption mechanism 2 includes a support frame 201 fixedly mounted on the upper part of the base plate 1.

[0036] Specifically, the auxiliary components include multiple fluid inlet pipes 206 fixedly mounted on the upper portion of the upper header 203.

[0038] Specifically, the air intake mechanism 3 includes two support platforms 301 fixedly mounted on the upper portion of the base plate 1. The two support platforms 301 are symmetrically distributed and provide stable support for the heat exchange tank body 302. The heat exchange tank body 302 is fixedly mounted on the upper portion of the support platforms 301. A base 303 is provided on one side of the heat exchange tank body 302. The base 303 is fixedly mounted on the upper portion of the base plate 1 and is used to support the air intake duct 304. The upper portion of the base 303 is fixedly connected to the air intake duct 304. A fan 305 is fixedly connected to one end of the air intake duct 304. The fan 305 transports the external cold flow gas through the air intake duct 304 to the interior of the heat exchange tank body 302. A second insulation jacket 306 is provided on the outside of the heat exchange tank body 302. The second insulation jacket 306 further reduces heat loss during the heat exchange process and maintains a stable temperature inside the tank body.

[0039] The circulation component in the heat exchange mechanism 4 includes a hot fluid pipe 401 disposed inside the heat exchange tank 302. One end of the fluid outlet pipe 207 is fixedly connected to one end of the hot fluid pipe 401. A plurality of heat conducting plates 402 are provided on the outer wall of the hot fluid pipe 401. The other end of the hot fluid pipe 401 is fixedly connected to a circulation pipe 405. A water pump 406 is provided on the outer wall of the circulation pipe 405. One end of the circulation pipe 405 is connected to the interior of the lower header 204.

[0040] Specifically, the circulation component in the heat exchange mechanism 4 includes a hot fluid pipe 401 disposed within the heat exchange tank 302. The hot fluid pipe 401 is fixedly connected to one end of the fluid outlet pipe 207. High-temperature fluid from the heat absorption mechanism 2 enters the hot fluid pipe 401 through the fluid outlet pipe 207. The outer wall of the hot fluid pipe 401 is provided with multiple heat conducting plates 402. The heat conducting plates 402 significantly expand the heat dissipation area of ​​the hot fluid pipe 401 and enhance the efficiency of heat transfer to the cold fluid. The other end of the hot fluid pipe 401 is fixedly connected to a circulation pipe 405. The outer wall of the circulation pipe 405 is provided with a water pump 406. The water pump 406 drives the hot fluid to circulate between the circulation pipe 405 and the heat absorption mechanism 2. One end of the circulation pipe 405 is connected to the interior of the lower header 204, forming a closed circulation system, ensuring that the hot fluid can continuously participate in the heat absorption and heat exchange process.

[0041] The dispersion component includes a flow dispersion plate 403 disposed at one end of the heat exchange tank 302, and a plurality of flow dispersion holes 404 are opened on the surface of the flow dispersion plate 403;

[0042] The dispersion assembly is arranged in front of the output end of the fan 305;

[0043] Specifically, the dispersion assembly includes a flow dispersion plate 403 disposed at one end of the heat exchange tank 302. The surface of the flow dispersion plate 403 is provided with a plurality of flow dispersion holes 404. When the cold fluid is delivered into the heat exchange tank 302 by the fan 305, it first passes through the flow dispersion plate 403. The flow dispersion holes 404 evenly disperse the cold fluid into a low-speed airflow. This avoids the problem of localized flow velocity unevenness caused by the airflow directly impacting the hot fluid pipe 401, increases the contact area and contact time between the cold fluid and the hot fluid pipe 401, and significantly improves heat exchange efficiency.

[0044] The gas outlet assembly includes a gas outlet pipe 407 fixedly connected to the other end of the heat exchange tank 302, a valve 2 408 is provided on the outer wall of the gas outlet pipe 407, and one end of the gas outlet pipe 407 is fixedly connected to an air storage box 409, which is fixedly mounted on the upper part of the bottom plate 1;

[0045] Specifically, the gas outlet assembly includes a gas outlet pipe 407 fixedly connected to the other end of the heat exchange tank 302. The high-temperature fluid after heat exchange is discharged from the heat exchange tank 302 through the gas outlet pipe 407. A second valve 408 is provided on the outer wall of the gas outlet pipe 407. This valve 408 controls the output volume and output rate of the high-temperature fluid to meet the storage requirements of the gas storage tank 409 and the stable operation of the subsequent power generation system. One end of the gas outlet pipe 407 is fixedly connected to the gas storage tank 409, which is fixedly mounted on the upper portion of the base plate 1 and is used to store the high-temperature fluid after heat exchange. In the event of insufficient sunlight or changes in power generation demand, the high-temperature fluid in the gas storage tank 409 can continuously provide energy to the power generation system, ensuring the continuity and stability of the power generation process.

[0046] The reflecting mechanism 5 includes two supporting legs 501 fixedly mounted around the upper part of the base plate 1, a motor 502 fixedly mounted on the inner side of the upper part of the two supporting legs 501, a reflecting mirror 503 is arranged between the two supporting legs 501, connecting plates 504 are fixedly mounted on both sides of the upper part of the reflecting mirror 503, the output ends of the two motors 502 are fixedly connected to the two connecting plates 504 respectively, and a displacement sensor 505 is arranged on the outer bottom of the reflecting mirror 503.

[0047] Specifically, the reflector mechanism 5 comprises two support legs 501, each fixedly mounted around the upper perimeter of the base plate 1. The two support legs 501 provide support and a mounting base for the reflector 503. A motor 502 is fixedly mounted on the inner side of each support leg 501. The motor 502 connects to the reflector 503 via a connecting plate 504, driving the reflector 503's rotation. A reflector 503 is positioned between the two support legs 501, effectively reflecting sunlight. Connecting plates 504 are fixedly mounted on either side of the reflector 503's upper portion. The output ends of the two motors 502 are fixedly connected to the connecting plates 504, respectively. The coordinated rotation of the two motors 502 allows for precise adjustment of the angle of the reflector 503. A displacement sensor 505 is mounted on the outer bottom of the reflector 503. This displacement sensor 505 monitors the position and angle of the reflector 503 in real time and feeds this data back to the controller 6, enabling the reflector 503 to dynamically track the sun's position, ensuring that sunlight is always precisely focused on the area supporting the air intake mechanism 3.

[0048] A controller 6 is provided on one side of the outside of the support frame 201;

[0049] Specifically, the controller 6 can dynamically adjust parameters such as the angle of the reflector 503, the flow rate and flow velocity of the fluid based on real-time monitored data such as the sun's position, fluid temperature, and fluid flow, to ensure that the device can maintain efficient and stable operation under different lighting conditions and working conditions, maximize the utilization of light energy and heat exchange efficiency, and realize the intelligence and automation of the solar thermal power generation process.

[0050] Working Principle: First, two motors 502 drive the reflectors 503 via a connecting plate 504. Displacement sensors 505 monitor the angles of the reflectors 503 in real time, ensuring they accurately track the sun's position and reflect and focus sunlight onto the area supporting the air intake mechanism 3. Multiple groups of reflectors 503 form a circular focusing array, significantly increasing the range and density of light energy captured, laying the foundation for the subsequent heat absorption process.

[0051] The support frame 201 is fixed to the base plate 1. Its internal insulation jacket 202 encases the upper and lower headers 203, 204, and heat-absorbing tubes 205, minimizing heat loss. The heat-absorbing tubes 205 are arranged in an array between the upper and lower headers 204. Their outer walls absorb solar energy focused by the reflectors 503 and transfer heat to the water inside the tubes. This heat is then transferred to the upper header 203 via the fluid inlet pipe 206 via the low-temperature fluid. After being heated by the heat-absorbing tubes 205, the high-temperature fluid is output to the heat exchange mechanism 4 through the fluid outlet pipe 207. Simultaneously, the fluid flow is controlled by valve 208, and a temperature sensor 209 monitors the temperature inside the upper header 203 in real time to ensure a stable heat absorption process.

[0052] The heat exchange tank 302 is secured by two support platforms 301, with an outer insulation jacket 306 maintaining internal temperature. A fan 305 delivers external cold air into the heat exchange tank 302 via an air inlet duct 304. The fluid first passes through the dispersion plate 403 of the dispersion assembly, where it then flows through the dispersion holes 404 to form a uniform, low-speed airflow, increasing the contact area with the hot fluid and improving heat exchange efficiency.

[0053] Hot fluid pipe 401 is connected to the fluid outlet pipe 207 of heat absorption mechanism 2. As the high-temperature fluid flows within the pipe, the heat conducting plate 402 on the outer wall expands the heat dissipation area and enhances heat conduction. Cold fluid flows around hot fluid pipe 401 within heat exchange tank 302, absorbing heat through interlayer heat exchange. After the temperature rises, it enters air storage tank 409 for storage through outlet pipe 407 of the air outlet assembly. After releasing heat, the hot fluid returns to lower header 204 through circulation pipe 405 and water pump 406, completing the closed cycle. During this process, the heat exchange area is increased by heat conducting plate 402, and the distribution of the cold fluid flow field is optimized by the flow dispersion holes 404. The synergistic effect of these two significantly improves heat transfer efficiency.

[0054] The controller 6 on the outside of the support frame 201 serves as the system center, and realizes full-process intelligent control through a sensor network and preset algorithms: on the one hand, the sun's position is calculated based on the data of the displacement sensor 505, and the motor 502 is driven to dynamically adjust the angle of the reflector 503 to ensure accurate focusing; on the other hand, based on the fluid temperature feedback from the temperature sensor 209, the valve 208 opening and the water pump 406 flow are adjusted to control the fluid temperature in the heat absorption tube 205 within the high-efficiency range; at the same time, the inlet and outlet fluid parameters of the heat exchange tank 302 are monitored, and the speed of the fan 305 is adjusted to optimize the flow rate of the cold fluid to ensure that the heat exchange is always in the best working condition.

[0055] The high-temperature fluid after heat exchange is stored in the gas storage tank 409 and can be directly connected to the power generation system to drive power generation and maintain output when there is insufficient light. In addition, the system is compatible with a variety of fluid media such as molten salt and supercritical carbon dioxide, and can be flexibly expanded to industrial heating, hydrogen production and other fields to meet the energy needs of different scenarios.

[0056] In summary, the device forms an efficient conversion path from solar energy to usable energy through the synergistic effects of concentration, heat absorption, heat exchange, and control mechanisms, breaking through the efficiency bottleneck of traditional solar thermal devices and providing the renewable energy field with an advanced technical solution that integrates high integration, intelligent control, and low energy consumption. It has significant engineering application value and market competitiveness.
