[0019] The application will be described in further detail below with reference to the drawings: Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein identical or similar labels represent identical or similar elements or elements having identical or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0020] Referring to Figure 1 The first aspect of the present application discloses a direct air cooling system based on wind-solar complementary power supply, which comprises a support base 1, a flow guide device 2, an air cooling fan 3, a spraying device 4, a flow guide cover type wind turbine 5, a photovoltaic panel 6, a vertical axis wind turbine 7, an A-type support 8, a heat dissipation pipe bundle 9 and a main pipe 10. Each group of A-type supports 8 and the flow guide device 2, the air cooling fan 3 installed below, the spraying device 4, the photovoltaic panel 6, the heat dissipation pipe bundle 9 and the main pipe 10 installed thereon together constitute a group of air cooling islands.

[0021] There are a plurality of A-type supports 8 arrayed on the support base 1, and the heat dissipation pipe bundle 9 is distributed on both sides of each A-type support 8. The setting direction of the heat dissipation pipe bundle 9 is the width direction of the both sides of the A-type support 8. The A-type support 8 is provided with the main pipe 10 along the length direction, and the main pipe 10 is communicated with the heat dissipation pipe bundle 9 on both sides. The A-type support 8 is arrayed with the air cooling fan 3 along the length direction. The steam of the turbine exhaust flows into the heat dissipation pipe bundle 9 through the main pipe 10, and the air cooling fan 3 blows upward to cool the steam in the heat dissipation pipe bundle 9.

[0022] There are a plurality of vertical axis wind turbines 7 provided on the support base 1, and a plurality of flow guide cover type wind turbines 5 are provided on the side wall of the support base 1. The vertical axis wind turbine 7 and the flow guide cover type wind turbine 5 are connected with the micro-grid controller.

[0023] The photovoltaic panel installed on the surface of the A-type support 8 converts solar energy into electric energy, which is connected with the wind power generation unit (vertical axis wind turbine 7 and flow guide cover type wind turbine 5) to the micro-grid system. The air cooling fan is arranged below the support, and the external flow guide device optimizes the air flow by adjusting the blade angle to avoid the reflux of hot air. The micro-grid controller coordinates the energy distribution of wind-solar power generation, energy storage battery and plant power consumption in real time, and preferentially supplies power to the flow guide device, air cooling fan and spraying device.

[0024] As preferred, the guide vane type wind turbine 5 is arranged on the windward side. After the guide vane type wind turbine is arranged on the windward side of the support base, the guide vane thereof can effectively utilize the natural wind direction to enhance the air intake amount of the wind turbine, thereby improving the power generation efficiency. The positioning on the windward side enables the wind turbine to be in the direct path of airflow impact under the dominant wind direction, avoiding energy loss caused by lateral wind. Meanwhile, the guide vane structure can preliminarily straighten the airflow entering the air cooling system, reducing the turbulence phenomenon caused by lateral wind, and thereby reducing the possibility of hot air backflow. The present application effectively solves the problem of hot air backflow caused by lateral wind, and enhances the controllability of airflow organization through directional arrangement of the wind turbine, thereby improving the wind power generation amount and improving the heat dissipation efficiency of the air cooling system, thereby reducing the plant power consumption rate and improving the system operation stability.

[0025] The A-shaped support 8 is provided with a double-layer spraying device, two water spraying pipelines arranged in the length direction are arranged on each side of the A-shaped support 8, and the upper water spraying pipeline and the lower water spraying pipeline are arranged on each water spraying pipeline. Each water spraying pipeline is provided with a nozzle; the lower water spraying pipeline pre-cools the incoming air, and the upper water spraying pipeline performs fin cooling; the lower cooling water pipeline is provided with a plurality of high-pressure micro-spray nozzles, each high-pressure spray nozzle is arranged between two heat dissipation pipe bundles 9, the high-pressure spray nozzle sprays towards the bottom, pre-cools the incoming air, and the upper cooling water pipeline is provided with a plurality of capillary nozzles, the capillary nozzles are integrated into the heat dissipation fins and act on local overheated points to realize precise evaporative cooling of the pipe wall. During operation, the lower water spraying pipeline pre-cools the airflow entering the air cooling system through atomizing spraying, reduces the temperature of the incoming air, and reduces the heat exchange load. The upper water spraying pipeline sprays towards the fin structure of the heat dissipation pipe bundle, and forms fine water droplets through high-pressure micro-spray to enhance the phase change cooling effect. The two sets of water spraying devices are respectively supplied with water through independent cooling water pipelines, and the water spraying amount of each set can be dynamically adjusted according to the environmental temperature and the unit back pressure. The present application solves the local overheating problem caused by poor uniformity of the traditional spraying system, optimizes the cooling water distribution through layered spraying and independent control, and forms a synergistic effect of pre-cooling and fin cooling. Under the conditions of lateral wind or high temperature, the upper and lower water spraying pipelines can adjust the spraying parameters in a targeted manner, effectively eliminate the temperature gradient on the surface of the heat dissipation pipe bundle, and avoid flow field disturbance caused by excessive single spraying.

[0026] Further, when the infrared detection detects that the local hot spot temperature difference on the fin of the A-shaped support 1 is greater than 8℃, the nozzle of the upper cooling pipeline acts accurately on the specified pipe bundle to eliminate the local hot spot.

[0027] The photovoltaic panel 6 is arranged on the two sides of each A-shaped support 8.

[0028] Referring to Figure 2Each outer side of the air cooling fan 3 is surrounded by a flow guide device, the flow guide device 2 is a ring structure, the flow guide device 2 comprises a ring-shaped support shaft 202, a plurality of blades 201 and an inner ring 203, the inner ring 203 and the ring-shaped support shaft 202 have the same center, the ring-shaped support shaft 202 is outside the inner ring 203, the outer sides of all the blades 201 are rotationally connected with the ring-shaped support shaft 202, and the blades 201 are circumferentially arranged between the inner ring 203 and the ring-shaped support shaft 202. When all the blades 201 are closed, different air inlet amounts are obtained, and when the blades 201 are rotated to have a certain opening, the gap between the blades 201 and the inner ring 203 allows the gas to flow in. The plurality of blades 201 are driven by an electric push rod and a magneto-rheological damper; the flow guide device dynamically adjusts the height and the inclination angle according to the flow field monitoring result of the space between the lower part of the A-shaped support 8 and the upper part of the air cooling fan 3, and effectively suppresses the heat backflow problem caused by the transverse wind.

[0029] The photovoltaic panel 6 of the present application adopts a single crystal silicon assembly, has an adjustable inclination angle of 25±5°, and covers the surfaces on both sides of the A-shaped support 8.

[0030] In some specific embodiments, the photovoltaic panel 6 is also partially embedded in the adjacent heat dissipation pipe bundle 9, adopts a strip-shaped flexible assembly, and the photovoltaic panel 6 covering the surface of the A-shaped support 8 requires that the air permeability is greater than 50% and the light transmittance is 80%.

[0031] The vertical axis wind turbine 7 of the present application is installed in the central low-pressure area of the adjacent A-shaped support 1, is far away from the air cooling fan 3 below the A-shaped support 1, prevents the wind force of the air cooling fan 3 from affecting the vertical axis wind turbine 7, and the blade height of each vertical axis wind turbine 7 is less than or equal to the radius of the fan impeller.

[0032] The flow guide cover fan 5 adopts a Venturi curved surface integrated with a steel structure; the energy storage system adopts a lithium iron phosphate battery pack, and simultaneously combines a bidirectional converter.

[0033] Referring to Figure 3 The wind and light power generation of the present application comprises the photovoltaic panel, the vertical axis wind turbine 7 and the flow guide cover type wind turbine 5, all of which are in communication with a micro-grid controller, the micro-grid controller supplies power for the air cooling system. The flow guide device is used to suppress the air heat backflow, a double-layer spraying system is configured to realize accurate cooling of the heat exchange pipe wall. Through a reinforcement learning algorithm, the operation mode of the flow guide element and the spraying device is intelligently controlled, and the safe and efficient operation of the unit cooling end is realized.

[0034] Further, the whole system is also provided with an energy storage battery and a double-phase converter, the energy storage system can be a lithium iron phosphate battery pack, and the energy storage battery is used to realize wind and light complementary power supply.

[0035] The system has a built-in power supply priority strategy, which compares the real-time wind and light power generation with the power demand of the air cooling system, and the power generation is preferentially supplied to the power demand of the air cooling system, and the excess power is stored in the battery; when the wind and light power supply is insufficient, the battery is discharged to make up the difference; if the battery power is still insufficient, further power is purchased from the power grid to make up for the shortage. The power supply strategy preferentially ensures the normal operation of the air cooling system and maintains the stability of the back pressure. The wind and light complementary power supply system integrates photovoltaic panels, wind turbines and other renewable energy equipment on the air cooling island structure, realizes the space sharing of wind and light power generation and the air cooling island body, and preferentially supplies the power generated by these equipment to the air cooling system. The excess power is stored in the energy storage system or connected to the grid, and the insufficient power is supplemented from the energy storage system or the power grid. This design greatly reduces the external power demand of the air cooling system, thereby reducing the plant power consumption rate.

[0036] The application also discloses an intelligent control device of the direct air cooling system. S1, collecting environmental parameters, flow field parameters and temperature field parameters; S2, controlling the opening of the blade 201 in the flow guide device 2, the flow rate of the spray device 4 and the rotating speed of the air cooling fan 3 based on the environmental parameters; S3, collecting the power consumption of the flow guide device 2, the spray device 4 and the air cooling fan 3 and the unit back pressure; when the unit back pressure is the optimal value and the power consumption of the flow guide device 2, the spray device 4 and the air cooling fan 3 is the minimum, the system is normally operated, otherwise, returning to S2 for re-regulation.

[0037] The environmental parameters include wind speed, wind direction, temperature and humidity, which can be monitored in real time by a meteorological sensor and are used for evaluating the influence of external conditions on the heat dissipation efficiency. The flow field parameter is the speed of the flow field under the A-shaped support, which can be measured by an ultrasonic anemometer and is used for judging whether the air flow organization is reasonable. The temperature field parameter is the temperature of the flow field under the A-shaped support and the temperature of the support itself, which can be detected by combining an infrared thermal imager with a thermocouple and is used for identifying local overheating areas. The optimal value of the unit back pressure can be determined by a preset back pressure-energy consumption curve, and historical operation data can be modeled to balance the heat dissipation efficiency and energy consumption.

[0038] The application effectively reduces the plant power consumption rate of the air cooling system, reduces the negative influence of hot air backflow by dynamically optimizing the blade angle of the flow guide device, and realizes the uniform distribution of spray cooling based on the temperature field parameter. Further, by monitoring the unit back pressure and energy consumption data in real time, the system is ensured to always operate at the optimal working condition point, and the core problem that the traditional control strategy cannot balance the heat dissipation efficiency and energy consumption is solved.

[0039] By controlling the opening of the guide vane 201 in the flow guide device and the flow rate of the spray in the spray device 4, the heat backflow can be suppressed and the heat dissipation efficiency can be improved, thereby optimizing the cooling effect of the steam and optimizing the back pressure. By controlling the speed of the air cooling fan 3, the energy consumption can be reduced, thereby reducing the overall power consumption in the plant.

[0040] The present application optimizes the algorithm to guide the operation of the flow guide element, the spray system and the fan group, and controls the charging and discharging of the energy storage through the experience of power consumption, so as to realize the efficient and stable operation of the air cooling system of the unit.

[0041] In some specific embodiments, according to the flow field parameters and temperature field parameters below the A-type support 8, the optimal action opening of the vane 201 is calculated according to the detection result, the position instruction of the electric push rod is given, and the height and inclination angle of the flow guide element are adjusted through closed-loop control.

[0042] Further, when strong transverse wind is detected, the system can instruct the flow guide element to be raised and adjusted to a specific angle to more effectively block the hot air backflow into the air inlet area.

[0043] Through preliminary analysis and verification, for the direct air cooling unit, the present scheme can effectively reduce the annual average back pressure, the annual power consumption of the fan and the water consumption of the spray system.
