Description

Technical Field

[0001] This invention relates to the field of cooling towers, and more particularly to an assembled, angle-adjustable cooling tower air guide device. Background Technology

[0002] Cooling towers are widely used in industrial production sectors such as power, chemical, petroleum, and steel. Their function is to exchange heat between cooling water carrying waste heat from industrial production and the air inside the tower, transferring the waste heat to the atmosphere. This addresses the problems of water waste and thermal pollution caused by direct-flow cooling. Natural draft counter-flow wet cooling towers (hereinafter referred to as air-cooled towers) are most widely used in my country's power sector due to their high heat exchange efficiency and low operating costs.

[0003] Existing research indicates that under medium-to-high wind speeds, heat transfer on the side and leeward sides of air-cooled towers is prone to deterioration, resulting in problems such as side and leeward suppression and slow airflow velocity within the tower. Furthermore, when air enters the cooling tower, vortices easily form within a 5-meter radius around the lower edge of the tower casing, reducing airflow velocity in this area and severely impacting the heat dissipation of circulating water. Therefore, only by improving the air intake conditions on the side and leeward sides of the tower, reducing side and leeward suppression, and optimizing airflow within the tower can the adverse effects of ambient wind on the heat transfer performance of air-cooled towers be mitigated.

[0004] To increase airflow velocity and cooling efficiency within the cooling tower, existing air guiding devices typically involve adding guide vanes or a central cross-shaped baffle. However, practical experience has shown that these traditional air guiding devices cannot fundamentally address the adverse effects of ambient wind on the heat transfer performance of air-cooled towers. Therefore, a targeted solution needs to be developed.

[0005] Traditional air deflectors cannot adjust their angle according to changes in external wind direction. Sometimes, they not only fail to accelerate airflow but also obstruct airflow into the cooling tower. Practice has shown that while cooling towers with fixed air deflectors exhibit significant airflow guidance during certain periods, their overall effect throughout the year is not noticeable. This indicates that air deflectors are effective when wind direction favors airflow, but obstruct airflow and inhibit cooling efficiency when wind direction is unfavorable. Furthermore, many cooling towers in my country are built in coastal areas prone to tornadoes, typhoons, and downbursts, where traditional air deflectors pose certain safety hazards under strong winds.

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0038] Please see Figure 1 and Figure 2 This invention discloses an adjustable-angle, prefabricated cooling tower air guiding device, comprising: a tower cylinder 1, a plurality of fixed plates 2 evenly arranged around the circumference of the tower cylinder 1, air guiding plates 3 mounted on the fixed plates 2, and a driving device connected to the air guiding plates 3. The fixed plates 2 serve as mounting bases for the air guiding plates 3 and are used for movable connection with the air guiding plates 3. The air guiding plates 3 are used to introduce ambient air into the cooling tower, thereby improving the airflow state inside the cooling tower and increasing the heat dissipation efficiency inside the cooling tower. Preferably, there is a predetermined gap between each air guiding plate 3. Under the action of ambient air, an air jet can be formed through the gap between the air guiding plates 3, which can eliminate the influence of vortices that are easily generated within about 5 meters around the lower edge of the cooling tower cylinder 1, thereby effectively improving the airflow field structure inside the natural ventilation indirect cooling tower or natural ventilation direct cooling tower and improving the cooling performance of the cooling tower.

[0039] The fixed plate 2 is equipped with a rotating shaft rotatably connected to it, and the rotating shaft is fixedly connected to the air guide plate 3. The driving device drives the air guide plate 3 to rotate around the rotating shaft, thereby giving the air guide plate 3 different angles relative to the horizontal plane. This driving device drives the air guide plate 3 to maximize the introduction of ambient air into the cooling tower under different wind speeds or directions. The operating speed of the driving device can be adjusted by the control system according to the working environment and real-time working conditions, ensuring the normal operation and long lifespan of the assembled angle-adjustable cooling tower air guide device, and improving its working efficiency. The driving device can be, but is not limited to, a servo motor or a stepper motor.

[0040] Understandably, this prefabricated, angle-adjustable cooling tower air guide device has the advantages of short construction cycle, easy installation and disassembly, and convenient maintenance. It can adapt to changes in environmental wind direction. Based on the wind direction and speed of the area where the air guide plate 3 is located, it can adjust the rotation of each corresponding air guide plate 3 by a certain angle to reduce the suppression of crosswinds and backwinds, as well as the influence of vortices, thereby optimizing the airflow inside the cooling tower and improving the cooling performance of the cooling tower.

[0041] In some embodiments, the fixing plate 2 is arc-shaped and is bolted to the tower 1. Understandably, the fixing plate 2 has an arc shape that matches the sidewall of the tower 1. When the fixing plate 2 is installed at the bottom of the tower 1, its inner surface fits against the sidewall of the tower 1, thus preventing gaps between the fixing plate 2 and the sidewall of the tower 1. In other embodiments, the fixing plate 2 may also be rectangular, U-shaped, or other shapes, as long as it matches the shape of the sidewall of the tower 1. Preferably, the fixing plate 2 and the tower 1 can be connected by high-strength bolts to achieve prefabricated installation, which can shorten the construction cycle and facilitate installation and disassembly. The high-strength bolts also ensure the stability and firmness of the connection between the fixing plate 2 and the tower 1. These high-strength bolts can be expansion bolts, which can effectively improve the connection stability between the bolt and the threaded hole, preventing the fixing plate 2 from falling off during long-term use.

[0042] Furthermore, the air guide plate 3 is a plate-shaped structure made of aluminum alloy, and the surface of the air guide plate 3 is provided with an anti-corrosion layer. Understandably, the air guide plate 3 has an overall flat plate-shaped structure. The aluminum alloy is lightweight and flexible, with low density, good strength, corrosion resistance, and good processing performance, ensuring the strength and rigidity of the air guide plate 3 and extending its service life. In other embodiments, the air guide plate 3 may also be made of carbon steel, stainless steel, or other metal materials; no specific limitations are made here.

[0043] The anti-corrosion layer can be a fluorocarbon layer, and the surface of the air guide plate 3 can be coated with fluorocarbon. Alternatively, the anti-corrosion layer can be a galvanized layer, effectively resisting corrosion from air pollution and acid rain. Preferably, the fixing plate 2 is a plate-shaped structure made of carbon steel, specifically Q235 high-quality carbon steel, ensuring the overall strength and rigidity of the assembled angle-adjustable cooling tower air guide device, and ensuring its stable operation. The fixing plate 2 can also be made of stainless steel or other metal materials, and can be manufactured by bending metal sheets using a digital machine tool. This ensures that the inner surface curvature of the fixing plate 2 matches the side wall curvature of the tower 1, while also improving the mechanical strength of the fixing plate 2 and reducing its manufacturing cost.

[0044] Preferably, the air guide plate 3 may be provided with rounded chamfers. By providing rounded chamfers, when the air guide plate 3 is guiding the air, the ambient air can flow from both sides of the air guide plate 3 with almost no resistance, reducing the interference of the air guide plate 3 on the flow of ambient air, and allowing the ambient air to quickly enter the interior of the cooling tower.

[0045] In some embodiments, the assembled angle-adjustable cooling tower air guide device further includes a wind speed sensor 4 and a wind direction sensor 5. The wind speed sensor 4 is located at the bottom of the tower 1 to detect the actual wind speed in the vicinity of the tower 1, and the wind direction sensor 5 is located at the bottom of the tower 1 to detect the actual wind direction in the vicinity of the tower 1. The assembled angle-adjustable cooling tower air guide device also includes a controller, which is communicatively connected to the wind speed sensor 4 and the wind direction sensor 5. Based on the actual wind speed and / or the actual wind direction, the controller adjusts the direction and / or magnitude of the driving force output by the drive device to the air guide plate 3, thereby allowing the air guide plate 3 to have different angles relative to the horizontal plane.

[0046] Specifically, when the actual wind speed is greater than or equal to a preset wind speed threshold, the controller controls the wind guide plate 3 to rotate to a closed position D parallel to the outer wall of the tower 1. When the actual wind speed is less than the preset wind speed threshold, the controller controls the wind guide plate 3 to rotate to a tilted position A, a parallel position B, or a downward tilted position C. When the wind guide plate 3 is in the tilted position A, it is positioned above the horizontal plane and tilted relative to the horizontal plane. When the wind guide plate 3 is in the parallel position B, it is parallel to the lower end face of the tower 1. When the wind guide plate 3 is in the downward tilted position C, it is positioned below the horizontal plane and tilted relative to the horizontal plane. Specifically, the preset wind speed threshold can be set based on weather forecast data or data detected by the on-site wind speed sensor 4. This ensures that the wind guide plate 3 can be promptly retracted and closed under different wind speed conditions, preventing damage from strong, unusual winds during severe convective weather. When the actual wind speed is greater than or equal to the preset wind speed threshold, or when severe convective weather such as typhoons, tornadoes or downbursts occurs, the wind deflector 3 can be placed in the closed position D in time to reduce the probability of wind damage to the wind deflector 3.

[0047] Preferably, when the actual wind speed is less than a preset wind speed threshold, the controller, based on the local wind direction and wind speed indication drive device of the cooling tower, drives the windward guide plate 3 to rotate to a downward angled position C. The controller also instructs the drive device to rotate the crosswind and leeward guide plates 3 to tilted positions A. This effectively reduces the suppression of airflow in the crosswind and leeward areas by the ambient wind in the windward area, allowing the crosswind and leeward ambient wind to enter the cooling tower accurately and efficiently. When the cooling tower is in a state of very low wind speed or no wind, the controller, based on the local wind direction and wind speed indication drive device of the cooling tower, rotates all the guide plates 3 to a parallel position B. Through this method, the tilt angle of the guide plates 3 can be adaptively adjusted under different actual wind direction conditions, maximizing the flow of ambient wind into the cooling tower.

[0048] In some embodiments, the prefabricated angle-adjustable cooling tower air guide device further includes a bottom support column 6 located at the bottom end of the tower 1 for positioning and fixing the tower 1. The bottom support columns 6 are staggered around the circumference of the tower 1. Understandably, the bottom support columns 6 are distributed in a herringbone pattern, which can stably support the entire cooling tower on the ground. The bottom support columns 6 can be fixed to the concrete structure by shear studs or high-strength bolts, which greatly enhances the strength and stability of the prefabricated angle-adjustable cooling tower air guide device.

[0049] The base support 6 can be connected to the tower 1 via fasteners or by welding, providing positioning support for the tower 1. The staggered arrangement of the base support 6 along the circumference of the tower 1 facilitates disassembly, inspection, and maintenance. The base support 6 can also be a combined structure; its arrangement and mechanical analysis can be reasonably demonstrated and optimized using necessary finite element analysis. The base support 6 is preferably made of stainless steel, which has good rigidity and strength and is corrosion-resistant. In other embodiments, the base support 6 can also be made of 20 steel, 45 steel, or other metals; no specific limitation is made here.

[0050] Furthermore, the prefabricated angle-adjustable cooling tower air guide device also includes an air inlet 11 located on the side wall of the tower 1. An airflow regulating valve 12 is installed at the air inlet 11. It also includes an air sensor 13 for measuring indoor air temperature and / or humidity. The controller is communicatively connected to the airflow regulating valve 12 and controls the opening or closing of the airflow regulating valve 12 based on the air parameter information measured by the air sensor 13. Understandably, the air sensor 13 can be used to measure air temperature and humidity, and can be used to calculate other relevant air parameters such as enthalpy, wet-bulb temperature, and dew point temperature. The controller can use the air parameter information to control the airflow regulating valve 12, thereby controlling the amount of air entering the cooling tower. This prefabricated angle-adjustable cooling tower air guide device can adjust the airflow of the cooling tower by setting the airflow regulating valve 12, ensuring the highest cooling efficiency of the cooling tower under various operating conditions, ensuring the safe and reliable operation of the cooling tower, and improving energy utilization.

[0051] Preferably, the air inlet 11 is provided with louvers 14, which include a plurality of parallel louver blades 141 spaced apart. An air inlet 142 is formed between every two louver blades 141 for air passage. The louvers 14 are inclined relative to the air inlet 11. Understandably, the louvers 14 in the air inlet 11 can block airborne debris. The inclination of the louvers 14 relative to the air inlet 11 causes the air inlet 142 to also be inclined relative to the air inlet 11. When airborne debris enters the cooling tower through the louvers 14, it falls along the extension direction of the air inlet 142 towards the inner wall between adjacent louver blades 141, preventing it from directly entering the cooling tower. Furthermore, the assembled angle-adjustable cooling tower air guide device also includes a dehumidifier 15 located in the air inlet 11 for removing moisture from the air after passing through the louvers 14. The dehumidifier 15 is used to remove moisture from the air and reduce the moisture content of the air.

[0052] Furthermore, both the drive unit and the fixed plate 2 are equipped with lubricating oil filling devices 7. It is understood that the lubricating oil filling device 7 may include an oil inlet and an oil outlet. The oil inlet may be located on one side of the drive unit, and the oil outlet may be located on the other side of the drive unit away from the oil inlet. Operators can use the oil inlet to lubricate the drive unit, fixed plate 2, and air guide plate 3, ensuring the normal operation of the assembled angle-adjustable cooling tower air guide device and extending its service life. Operators can use high-quality lubricating oil and establish a regular maintenance plan. In some other embodiments, the assembled angle-adjustable cooling tower air guide device may also be equipped with an automatic lubricator, which can be connected to the lubricating oil filling device 7 to achieve automatic oil filling and improve work efficiency.

[0053] Preferably, the prefabricated angle-adjustable cooling tower air guide device further includes a vibration measuring device 8 installed on the side wall of the tower 1. This prefabricated angle-adjustable cooling tower air guide device may have vibration measuring heads installed in both vertical and horizontal directions. The vibration signals are transmitted to a control and monitoring box for real-time monitoring, ensuring that the fan operates under low-level vibration conditions. The data measured by the vibration measuring device 8 is transmitted to the controller. Simultaneously, a seismic test is conducted to verify the performance of the prefabricated angle-adjustable cooling tower air guide device before and after the seismic test, to verify whether the prefabricated angle-adjustable cooling tower air guide device can meet the requirements for earthquake resistance, tornado resistance, and shock wave resistance, ensuring that the prefabricated angle-adjustable cooling tower air guide device can operate normally in harsh environments.

[0054] The beneficial effects of this modular, angle-adjustable cooling tower air guide device are:

[0055] 1. This modular, angle-adjustable cooling tower air guide device can be installed in a modular manner, which has the advantages of short construction period, convenient installation and disassembly, and easy maintenance.

[0056] 2. This modular, angle-adjustable cooling tower air guide device can adapt to changes in ambient wind direction. Based on the ambient wind direction and speed in the area where the cooling tower is located, the control and execution system controls and adjusts the rotation angle of each air guide module to achieve intelligent adjustment of the air guide plate 3, thereby reducing the suppression of crosswinds and leewinds, as well as the influence of vortices, thus optimizing the airflow inside the cooling tower and improving the cooling performance of the cooling tower;

[0057] 3. The assembled adjustable-angle cooling tower air guide device can close the air guide plate 3 when strong winds come, thereby reducing the probability of the air guide device being damaged by wind.

[0058] 4. The air guide plate 3, the fixing plate 2, etc. have sufficient mechanical strength, and the surfaces of the air guide plate 3, the fixing plate 2, etc. are provided with an anti-corrosion layer, ensuring that the assembled angle adjustable cooling tower air guide device can be used in highly corrosive gas environments for a long time, extending its service life, and also enabling the assembled angle adjustable cooling tower air guide device to still operate normally in harsh environments.

[0059] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention.
