Description

Technical Field

[0001] This invention relates to the field of air-cooled tower technology, and more specifically to a high-efficiency air guiding device for air-cooled towers. Background Technology

[0002] The precooling system is an indispensable part of the air separation system. After filtration and compression, the air temperature is relatively high and must be cooled by a precooling system. The air-cooling tower is an essential part of the precooling system. Only after the compressed air is cooled by the air-cooling tower can it enter the downstream purification system.

[0003] Existing air-cooled towers lack corresponding air guiding mechanisms during operation, resulting in uneven airflow through the packing layer and poor pre-cooling performance. To address this technical problem, patent publication number CN218895680U proposes a design where air enters the tower body through the air inlet and then flows into the air guide duct. The air then passes through the air cover and is finally discharged onto the packing layer via an arc-shaped groove on the top cover. However, the top cover completely blocks the air outlet cover, allowing air to flow upwards only when the arc-shaped groove connects with the exhaust duct. This results in only a single area of ​​air flowing upwards, leading to uneven air distribution within the air-cooled tower. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for guiding air in air-cooled towers to achieve uniform gas distribution.

[0005] The objective of this invention can be achieved through the following technical solutions: A high-efficiency air guiding device for an air-cooled tower includes a tower body. A support ring is fixedly installed inside the tower body. A mounting ring is rotatably installed on the support ring and arranged coaxially. A horizontal plate is fixedly installed inside the mounting ring. A column is fixedly installed on the horizontal plate and arranged coaxially with the mounting ring. Multiple sets of air guiding blades are rotatably installed on the column via a mounting rod. The end of the mounting rod away from the column passes through the mounting ring and is rotatably connected to the mounting ring. A first motor that drives the mounting ring to rotate is fixedly installed on the outer side of the tower body. Multiple sets of brackets corresponding to the positions of the mounting rods are installed on the outer side of the mounting ring. A rack is slidably installed on the bracket, and the rack meshes with a gear fixedly installed at the end of the corresponding mounting rod. An electric telescopic rod that drives multiple sets of racks to move synchronously is installed inside the tower body.

[0006] As a further aspect of the present invention: multiple sets of the wind guide blades are arranged in a circular array around the axis of the column.

[0007] As a further aspect of the present invention: the output shaft of the first motor extends into the tower body and is distributed along the radial direction of the mounting ring. A bevel gear is fixedly installed at the end of the output shaft of the first motor. The bevel gear meshes with a bevel gear ring fixedly installed on the mounting ring. The bevel gear ring and the mounting ring are coaxially arranged.

[0008] As a further aspect of the present invention: the electric telescopic rod is provided in multiple sets and fixedly installed inside the tower body. The electric telescopic rods are distributed along the axial direction of the mounting ring. A U-shaped lifting frame is fixedly installed at the end of the electric telescopic rod. A lifting ring is provided inside the lifting frame. The lifting ring is coaxially arranged with the mounting ring and is fixedly connected to multiple sets of racks.

[0009] As a further aspect of the present invention: ball bearings are rotatably installed on the horizontal surface inside the lifting frame, and the ball bearings make rolling contact with the side of the lifting ring.

[0010] As a further aspect of the present invention: the tower body is provided with multiple sets of distribution rings with successively decreasing diameters, the distribution rings are provided with multiple sets of spaced through holes, the multiple sets of distribution rings are distributed in a frustum shape and the frustum is coaxially arranged with the mounting ring, each set of distribution rings is spaced apart, the multiple sets of distribution rings are fixedly connected by connecting rods, and the set of distribution rings closest to the mounting ring is fixedly connected to the inner wall of the tower body.

[0011] As a further embodiment of the present invention: a sealing plate is fixedly installed at the bottom of the tower body, an air inlet pipe is fixedly installed on the sealing plate, the air inlet pipe passes through the sealing plate, a retaining ring is fixedly installed inside the tower body, the retaining ring is connected to the air inlet pipe, an exhaust groove is connected on the retaining ring, a rotating ring is rotatably installed inside the retaining ring, a plurality of sets of spaced grooves are opened on the outer side of the rotating ring, and a second motor is provided inside the tower body to drive the rotating ring to rotate.

[0012] As a further embodiment of the present invention: a mounting frame is fixedly installed on the closed plate, and a rotating shaft coaxially arranged with the rotating ring is rotatably installed on the mounting frame. A second motor is fixedly installed on the mounting frame and is used to drive the rotating shaft to rotate. Multiple sets of support rods are fixedly installed on the rotating shaft, and the support rods are fixedly connected to the rotating ring.

[0013] As a further aspect of the present invention: a grid plate located between the retaining ring and the mounting ring is fixedly installed inside the tower body.

[0014] The beneficial effects of this invention are: (1) In this invention, multiple sets of air guide blades and the rotation of the air guide blades are used to actively guide and redistribute the airflow passing through the mounting ring, so that the gas can be evenly distributed in the internal air of the tower. When the gas flows upward, it can fully contact the packing above, thus improving the cooling effect. The electric telescopic rod drives the mounting rod to rotate, thereby changing the opening and closing angle of the air guide blades. By adjusting the angle of the air guide blades, the flow velocity field and coverage uniformity of the airflow can be changed, effectively eliminating the vortex area and ventilation dead angle caused by uneven airflow distribution, and further improving the cooling effect.

[0015] (2) In this invention, part of the gas passing through the mounting ring flows upward through the through hole on the distribution ring, part flows upward through the gap between the two sets of distribution rings, and part of the gas flows along the distribution ring so that a small amount of gas can move to the area above the column, thereby further reducing the influence of the column on the uniform distribution of gas, further improving the uniformity of gas distribution, and improving the cooling effect.

[0016] (3) In this invention, the closed space formed by the groove and the baffle ring reduces the flow rate loss of the air entering the tower body in the area. Subsequently, when the air in the area moves upward from the exhaust groove, it only has an upward speed, which avoids the air entering the tower body having a fast initial speed and passing through the guide vanes, ensuring that the guide vanes can distribute the gas evenly.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 As shown, the present invention is a high-efficiency air guiding device for an air-cooled tower, comprising a tower body 1, a support ring 4 fixedly installed inside the tower body 1, an mounting ring 5 rotatably mounted on the support ring 4 and arranged coaxially, a horizontal plate 6 fixedly installed inside the mounting ring 5, a column 7 coaxially mounted on the horizontal plate 6 and the column 7, and multiple sets of air guiding blades 8 rotatably mounted on the column 7 via a mounting rod 30, the multiple sets of air guiding blades 8 being arranged in a circular array around the axis of the column 7, the end of the mounting rod 30 away from the column 7 passing through the mounting ring 5 and being rotatably connected to the mounting ring 5, a first motor 18 for driving the mounting ring 5 to rotate fixedly installed on the outer side of the tower body 1, the output shaft of the first motor 18 extending into the tower body 1 and distributed along the radial direction of the mounting ring 5, a bevel gear 17 fixedly installed at the end of the output shaft of the first motor 18, the bevel gear 17 meshing with a bevel gear ring 16 fixedly mounted on the mounting ring 5, the bevel gear ring 16 being coaxially arranged with the mounting ring 5; Multiple sets of brackets 10 corresponding to the positions of the mounting rods 30 are installed on the outer side of the mounting ring 5. A rack 11 is slidably installed on the bracket 10. The rack 11 meshes with the gear 9 fixedly installed at the end of the corresponding mounting rod 30. An electric telescopic rod 13 is provided inside the tower body 1 to drive the multiple sets of racks 11 to move synchronously.

[0029] In practical application, air enters the tower body 1 from the bottom. The first motor 18 drives the mounting ring 5 to rotate at a set speed via the bevel gear 17 and bevel gear ring 16. As the mounting ring 5 rotates, it drives multiple sets of internal guide vanes 8 to rotate synchronously. After entering the bottom of the tower body 1, the air flows upwards, passing through the multiple sets of guide vanes 8. The rotation of the multiple sets of guide vanes 8 actively guides and redistributes the airflow passing through the mounting ring 5, ensuring that the gas evenly fills the interior of the tower body 1. Subsequent gas... When flowing upwards, it can fully contact the packing material above, improving the cooling effect. Depending on the actual use, multiple sets of racks 11 can be moved upwards or downwards synchronously by the electric telescopic rod 13. When the racks 11 move, they drive the mounting rod 30 to rotate through the meshing gear 9, thereby changing the opening and closing angle of the guide vanes 8. By adjusting the angle of the guide vanes 8, the flow velocity field and coverage uniformity of the airflow can be changed, effectively eliminating vortex areas and ventilation dead zones caused by uneven airflow distribution, further improving the cooling effect. Finally, the gas leaves the tower body 1 from the top.

[0030] Please see Figure 2 , Figure 3 , Figure 8 As shown, the present invention is a high-efficiency air guiding device for an air-cooled tower. Multiple sets of electric telescopic rods 13 are provided and fixedly installed inside the tower body 1. The electric telescopic rods 13 are distributed along the axial direction of the mounting ring 5. A U-shaped lifting frame 14 is fixedly installed at the end of the electric telescopic rod 13. A lifting ring 12 is provided inside the lifting frame 14. The lifting ring 12 is coaxially arranged with the mounting ring 5 and is fixedly connected to multiple sets of racks 11. Specifically, ball bearings 15 are rotatably installed on the horizontal surface inside the lifting frame 14, and the ball bearings 15 roll into contact with the side of the lifting ring 12.

[0031] In practical application, the electric telescopic rod 13 drives the lifting frame 14 to move up and down. The lifting frame 14 drives the lifting ring 12 to move up and down through the ball bearings 15. In turn, the lifting ring 12 drives the rack 11 to move up and down. The ball bearings 15 reduce the wear between the lifting ring 12 and the lifting frame 14. Moreover, the rotation of the mounting ring 5 does not affect the angle adjustment of the guide vane 8, so as to realize the rapid adjustment response of the equipment, reduce the limitation of the equipment use, and further improve the cooling effect.

[0032] Please see Figure 2 , Figure 4As shown, the present invention is a high-efficiency air guiding device for an air-cooled tower. The tower body 1 is provided with multiple sets of distribution rings 28 with successively decreasing diameters. Multiple sets of through holes are opened on the distribution rings 28. The multiple sets of distribution rings 28 are distributed in a frustum shape and the frustum is coaxially arranged with the mounting ring 5. There is a gap between each set of distribution rings 28. The multiple sets of distribution rings 28 are fixedly connected by connecting rods 29. The set of distribution rings 28 closest to the mounting ring 5 is fixedly connected to the inner wall of the tower body 1.

[0033] In practical application, after passing through the mounting ring 5, the gas rises and contacts the distribution ring 28. Some of the gas flows upward through the through holes on the distribution ring 28, and some flows upward through the gap between the two sets of distribution rings 28. Some of the gas flows along the distribution ring 28, allowing a small portion of the gas to move towards the area above the column 7. This further reduces the influence of the column 7 on the uniform distribution of the gas, further improves the uniformity of the gas distribution, and enhances the cooling effect.

[0034] Please see Figure 2 , Figure 5 , Figure 6 As shown, the present invention is a high-efficiency air guiding device for an air-cooled tower. A sealing plate 3 is fixedly installed at the bottom of the tower body 1, and an air inlet pipe 2 is fixedly installed on the sealing plate 3. The air inlet pipe 2 passes through the sealing plate 3. A retaining ring 25 is fixedly installed inside the tower body 1. The retaining ring 25 is connected to the air inlet pipe 2. An exhaust groove 26 is connected to the retaining ring 25. A rotating ring 23 is rotatably installed inside the retaining ring 25. Multiple sets of spaced grooves 24 are opened on the outer side of the rotating ring 23. A second motor 22 is provided inside the tower body 1 to drive the rotating ring 23 to rotate.

[0035] Specifically, a mounting bracket 19 is fixedly installed on the closed plate 3, and a rotating shaft 20 coaxially arranged with the rotating ring 23 is rotatably installed on the mounting bracket 19. The second motor 22 is fixedly installed on the mounting bracket 19 and is used to drive the rotating shaft 20 to rotate. Multiple sets of support rods 21 are fixedly installed on the rotating shaft 20, and the support rods 21 are fixedly connected to the rotating ring 23.

[0036] Specifically, a grid plate 27 is fixedly installed inside the tower body 1 between the retaining ring 25 and the mounting ring 5.

[0037] In practical application, the second motor 22 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the rotating ring 23 to rotate via the support rod 21. When the gas enters the tower body 1 through the air inlet pipe 2, it enters the groove 24 corresponding to the air inlet pipe 2. As the rotating ring 23 rotates, the gas-filled groove 24 and the baffle ring 25 form a closed space. When the groove 24 moves to the area of ​​the exhaust groove 26, the air moves upward through the exhaust groove 26. The upward-flowing air is redistributed through the grid plate 27. The closed space formed by the groove 24 and the baffle ring 25 reduces the flow rate loss of the air entering the tower body 1 in this area. Subsequently, when the air in this area moves upward from the exhaust groove 26, it only has an upward speed, avoiding the air entering the tower body 1 with a high initial velocity and passing through the guide vanes 8, ensuring that the guide vanes 8 can distribute the gas evenly.
