Description

Technical Field

[0001] This application relates to the technical field of cooling towers, and in particular to a cooling tower with a circulating water cooling air diversion device. Background Art

[0002] The cooling tower in a waste incineration treatment plant is mainly used for cooling and treating the heat generated during the incineration process. High-temperature gases are generated during the incineration process, and the role of the cooling tower is to reduce the temperature of these gases and equipment to an appropriate level through a water cooling system, thereby protecting the equipment and reducing the environmental temperature to ensure the safety of the plant area and the surrounding area.

[0003] The current cooling tower body has air inlets on both sides of the lower part, and the air is drawn out by a cooling tower fan at the upper part. The circulating water is shunted by inclined pipes in the cooling tower for heat exchange, thereby reducing the temperature of the circulating water. However, due to the lack of guidance for natural wind at the lower air inlets, the natural wind is not evenly inhaled, and the cooling effect in some areas is relatively low. Summary of the Invention

[0004] In order to improve the cooling effect of the inclined pipes in the cooling tower, this application provides a cooling tower with a circulating water cooling air diversion device.

[0005] A cooling tower with a circulating water cooling air diversion device provided by this application adopts the following technical solutions:

[0006] A cooling tower with a circulating water cooling air diversion device includes a cooling tower body. Air inlets are provided on both symmetric sides of the cooling tower body. An exhaust duct is communicated with the top surface of the cooling tower body, and an air extraction fan is arranged in the exhaust duct. A fixed frame is arranged at the air inlet. A main guide vane and a plurality of auxiliary guide vanes are arranged in the fixed frame. Transmission shafts are respectively arranged at both ends of the main guide vane and the plurality of auxiliary guide vanes. The main guide vane and the plurality of auxiliary guide vanes are respectively rotationally connected to the fixed frame through the transmission shafts. The fixed frame is provided with a transmission mechanism for simultaneously driving the main guide vane and the plurality of auxiliary guide vanes to swing.

[0007] By adopting the above technical solutions, when it is necessary to cool the inclined pipes in the cooling tower body, the air extraction fan is started, and the external dry air is inhaled into the cooling tower body through the air inlet. At this time, the dry air passes through the inclined pipes and exchanges heat with the inclined pipes, thereby realizing the cooling of the inclined pipes. When it is necessary to adjust the flow direction of the dry air, the swing angle of the main guide vane is adjusted at this time. The main guide vane then drives the plurality of auxiliary guide vanes to swing synchronously through the transmission mechanism. Under the combined guiding action of the main guide vane and the plurality of auxiliary guide vanes, the flow direction of the dry air flowing through the air inlet is changed, so that the dry air blows evenly towards the inclined pipes, thereby improving the cooling effect of the inclined pipes in the cooling tower.

[0008] Optionally, the transmission mechanism includes a motor. One end of the transmission shaft extends into the cavity of the fixed frame, the motor is arranged in the cavity of the fixed frame, and the output shaft of the motor is fixedly connected to the transmission shaft corresponding to the main flow deflector. Adjacent transmission shafts are respectively connected with synchronous belt pulleys in a transmission manner.

[0009] By adopting the above technical solution, when it is necessary to adjust the flow direction of the drying air, the motor is started. The output shaft of the motor drives the transmission shaft to rotate, the transmission shaft drives the main flow deflector to swing, the main flow deflector drives the adjacent transmission shafts to rotate synchronously through the synchronous belt pulleys, and the adjacent transmission shafts then drive the corresponding auxiliary flow deflectors to swing. At this time, the main flow deflector and multiple auxiliary flow deflectors swing synchronously, and guide the drying air flowing through the air inlet, which is beneficial to improving the stability of the uniform flow of the drying air to the inclined pipes in the cooling tower.

[0010] Optionally, the transmission mechanism includes a rack.

The main flow deflector drives the gear of the corresponding transmission shaft to rotate, the gear drives the rack to move, and the rack finally drives multiple auxiliary flow deflectors to swing through the gear. At this time, the main flow deflector and multiple auxiliary flow deflectors swing simultaneously, and guide the drying air flowing through the air inlet, which is beneficial to improving the stability of the uniform flow of the drying air to the inclined pipes in the cooling tower.

[0012] Optionally, the swinging assembly includes a swinging pair and a swinging rod.

[0013] By adopting the above technical solution, when the driving member drives the connecting shaft to rotate, the connecting shaft drives the swinging pair to rotate, the swinging pair drives the swinging rod to swing. Under the continuous rotation of the connecting shaft, the swinging rod finally drives the main flow deflector to swing reciprocally. The main flow deflector synchronously drives multiple auxiliary flow deflectors to swing reciprocally through the gear and the rack, so that the drying air flows through the inclined pipes evenly, which is beneficial to improving the stability of the reciprocal swinging of the main flow deflector and multiple auxiliary flow deflectors.

[0014] Optionally, the driving member is a sector body, the sector body is rotationally and movably arranged in the fixed frame, a cross bar is arranged at one end of the sector body, a square block is arranged at one end of the cross bar, a square groove is formed at one end of the connecting shaft, and the square block is inserted into the square groove.

[0015] By adopting the above technical solution, when the dry air flows through the air inlet, the dry air drives the sector body to rotate, the sector body drives the connecting shaft to rotate through the cross bar, and the connecting shaft finally drives the main flow guide vane and a plurality of auxiliary flow guide vanes to swing reciprocally together. Also, when it is necessary to keep the main flow guide vane and a plurality of auxiliary flow guide vanes stationary at a certain swinging angle, drive the cross bar to move away from the main flow guide vane. At this time, the square block disengages from the square groove, and the main flow guide vane and a plurality of auxiliary flow guide vanes are stationary at the current swinging angle, which is beneficial to improving the stability of the reciprocal swinging or stationary current swinging angle of the main flow guide vane and a plurality of auxiliary flow guide vanes.

[0016] Optionally, a moving rod is sleeved on the side wall of the cross bar, both ends of the moving rod respectively extend into the cavity of the fixed frame, a moving groove is formed on the inner wall of the fixed frame, both ends of the moving rod are arranged in an L shape, the moving rod is slidably connected with the moving groove, and the cooling tower body is provided with a locking component for fixing the moving rod.

At this time, the square block disengages from the square groove, and the sector body releases the drive of the connecting shaft, which is beneficial to improving the stability of the reciprocal swinging or stationary current swinging angle of the main flow guide vane and a plurality of auxiliary flow guide vanes.

[0018] Optionally, the locking component includes a lock seat, the lock seat is arranged on the outer wall of the fixed frame, a lock rod is slidably arranged in the lock seat, two lock holes are formed on the side wall of the moving rod, the lock rod is respectively inserted into the two lock holes, a spring is sleeved on the side wall of the lock rod, one end of the spring is fixedly connected with the side wall of the lock rod, and the other end of the spring is fixedly connected with the inner wall of the lock seat.

[0019] By adopting the above technical solution, when it is necessary to move the sector body, first drive the lock rod to move away from the moving rod. At this time, the lock rod compresses the spring, and the lock rod disengages from the lock hole, and the moving rod is released from the restriction. By driving the moving rod to move, the sector body is finally driven to move. Also, when the lock rod is released, the spring releases the elastic force and drives the lock rod to move towards the moving rod. At this time, the lock rod is inserted into one of the lock holes, and the moving rod is fixed at the current position, which is beneficial to improving the stability of the connection or disconnection of the sector body through the cross bar and the connecting shaft.

[0020] Optionally, the other end of the transmission shaft corresponding to the main flow guiding plate extends into the cavity of the fixed frame. A first bevel gear is fixedly sleeved on the other end of the transmission shaft, and the fixed frame is provided with a rotating member for driving the first bevel gear to rotate.

[0021] By adopting the above technical solution, when it is necessary to manually adjust the swing angles of the main flow guiding plate and multiple auxiliary flow guiding plates, first, the rotating member drives the first bevel gear to rotate, the first bevel gear drives the transmission shaft to rotate, the transmission shaft drives the main flow guiding plate to swing, and the transmission shaft drives multiple auxiliary flow guiding plates to swing simultaneously through gears and racks. Therefore, it is beneficial to facilitate the manual adjustment of the swing angles of the main flow guiding plate and the auxiliary flow guiding plates.

[0022] Optionally, the rotating member is a knob. The knob is rotatably arranged on the surface of the fixed frame. One end of the knob is provided with a rotating rod. The rotating rod extends into the cavity of the fixed frame. A second bevel gear is fixedly sleeved on one end of the rotating rod, and the first bevel gear meshes with the second bevel gear.

[0023] By adopting the above technical solution, when the knob is rotated, the knob drives the second bevel gear to rotate through the rotating rod, the second bevel gear drives the first gear to rotate, and the first bevel gear thus drives the main flow guiding plate to swing through the transmission shaft. Therefore, it is beneficial to improve the convenience of driving the main flow guiding plate to swing manually.

[0024] In summary, the present application includes the following beneficial technical effects:

[0025] When it is necessary to cool the inclined pipe in the cooling tower body, start the air extraction fan. The external dry air is inhaled into the cooling tower body through the air inlet.

Also, when it is necessary to adjust the flow direction of the dry air, at this time, adjust the swing angle of the main flow guiding plate. The main flow guiding plate then drives multiple auxiliary flow guiding plates to swing synchronously through the transmission mechanism. Under the combined guiding action of the main flow guiding plate and multiple auxiliary flow guiding plates, the flow direction of the dry air flowing through the air inlet is changed, so that the dry air blows uniformly towards the inclined pipe, thereby improving the cooling effect of the inclined pipe in the cooling tower.

Detailed description of the specific implementation

[0036] The following is a further detailed description of the present application in conjunction with the attached Figures 1-9 drawings.

[0037] Embodiment 1:

[0038] See Figure 1 and Figure 2, a cooling tower with a circulating water cooling air diversion device, comprising a cooling tower body 1. Air inlets 2 are symmetrically arranged on both the front and back sides of the cooling tower body 1, and the number of air inlets 2 on each side is four, and the four air inlets 2 are arranged in parallel. The top surface of the cooling tower body 1 is fixedly communicated with exhaust ducts 3, and the number of exhaust ducts 3 is two. The two exhaust ducts 3 are arranged in parallel, and exhaust fans 4 are fixedly installed in the two exhaust ducts 3 respectively. A fixed frame 5 is fixedly installed in each air inlet 2, and a main guide vane 6 and auxiliary guide vanes 7 are installed in the fixed frame 5. Among them, the number of auxiliary guide vanes 7 is multiple, and the multiple auxiliary guide vanes 7 are symmetrically arranged with the main guide vane 6 as the center. The two ends of the main guide vane 6 and the multiple auxiliary guide vanes 7 are respectively fixedly connected with transmission shafts 8, and the main guide vane 6 and the multiple auxiliary guide vanes 7 are respectively rotatably installed in the fixed frame 5 through the transmission shafts 8. The fixed frame 5 is also provided with a transmission mechanism for simultaneously driving the main guide vane 6 and the multiple auxiliary guide vanes 7 to swing.

[0039] The main function of the cooling tower body 1 is to reduce the water temperature through the heat exchange between water and air, so as to ensure the normal operation of the system. When the exhaust fans 4 in the exhaust ducts 3 are started, the dry air from the outside is sucked into the cooling tower body 1 through the air inlets 2. When the dry air flows through the air inlets 2, the main guide vane 6 and the multiple auxiliary guide vanes 7 guide the dry air, so that the dry air uniformly flows into the cooling tower body 1 and exchanges heat with the inclined pipes in the cooling tower body 1. Also, when it is necessary to adjust the diversion angles of the main guide vane 6 and the auxiliary guide vanes 7, the transmission mechanism simultaneously drives the main guide vane 6 and the auxiliary guide vanes 7 to swing, so as to improve the cooling effect of the inclined pipes in the cooling tower body 1 according to the actual required incoming air direction.

[0040] Specifically, refer to Figures 2-4 , the transmission mechanism includes a rack 9. One end of the transmission shaft 8 extends into the cavity of the fixed frame 5, and a gear 10 is fixedly sleeved on one end of the transmission shaft 8. The rack 9 is arranged vertically, the rack 9 is slidably installed in the cavity of the fixed frame 5, and the rack 9 is simultaneously meshed with multiple gears 10.

[0041] In addition, to facilitate driving the main guide vane 6 to swing, the fixed frame 5 is also provided with a swing assembly, and the swing assembly includes a swing pair 11 and a swing rod 12. A swing groove 13 is formed in the side wall of the main guide vane 6. The swing rod 12 is installed in the fixed frame 5, one end of the swing rod 12 extends into the swing groove 13, and one end of the swing rod 12 is hinged to the groove wall of the swing groove 13. A fixed seat 14 is fixedly connected to the inner bottom wall of the fixed frame 5, and a connecting shaft 15 is rotatably installed in the fixed seat 14. The swing pair 11 is arranged at an obtuse angle, one end of the swing pair 11 is fixedly connected to the connecting shaft 15, and the other end of the swing pair 11 is rotatably connected to the swing rod 12.

[0042] When the connecting shaft 15 is driven to rotate, the connecting shaft 15 drives the swinging pair 11 set at an obtuse angle to swing. Under the continuous rotation of the connecting shaft 15, the swinging pair 11 drives the swinging rod 12 to swing, and the swinging rod 12 drives the main guide vane 6 to swing back and forth. The main guide vane 6 drives the gear 10 to rotate back and forth through the transmission shaft 8, and the gear 10 drives the rack 9 to move up and down, and the rack 9 then drives the auxiliary guide vane 7 to swing back and forth through the corresponding gear 10. By swinging and guiding the main guide vane 6 and the auxiliary guide vane 7 at the same time, the dry air flowing through the air inlet 2 is evenly blown to the inclined tube in the cooling tower body 1, thereby improving the cooling effect of the inclined tube.

[0043] See also Figure 3 and Figure 4 In order to facilitate the continuous rotation of the connecting shaft 15, a driving member is installed on the fixed frame 5, and the driving member is a fan body 16. The fan body 16 is rotatably and movably installed in the fixed frame 5. A cross bar 17 is coaxially fixedly connected to the inner side of the fan body 16. A block 18 is fixedly connected to one end of the cross bar 17 facing the main flow blade 6. A square groove 19 is opened at the end of the connecting shaft 15 away from the main flow blade 6, and the block 18 is plugged into the square groove 19.

[0044] When dry air flows through the air inlet 2, the dry air drives the fan body 16 to rotate, the fan body 16 drives the cross bar 17 to rotate, the cross bar 17 drives the connecting shaft 15 to rotate continuously through the block 18, the connecting shaft 15 drives the swing pair 11 to rotate, the swing pair 11 drives the swing rod 12 to swing, the swing rod 12 then drives the main guide vane 6 to swing back and forth, and the main guide vane 6 finally drives the auxiliary guide vane 7 to swing synchronously.

[0045] It is worth noting that see Figure 2 , Figure 3 and Figure 5 In order to make the main guide vane 6 and the auxiliary guide vane 7 stationary at a certain swing angle, a moving rod 20 is rotatably sleeved on the side wall of the crossbar 17. The two ends of the moving rod 20 are L-shaped, and the two ends of the moving rod 20 extend into the frame cavity of the fixed frame 5. The inner wall of the fixed frame 5 is symmetrically provided with moving grooves 21, and the two ends of the moving rod 20 are slidably connected to the moving grooves 21.

[0046] In addition, in order to facilitate the fixing of the moving rod 20, the cooling tower body 1 is also equipped with a locking assembly, which includes a lock seat 22, which is fixedly connected to the outer wall of the fixed frame 5, and a lock rod 23 is slidably penetrated in the lock seat 22. The side wall of the moving rod 20 is provided with a lock hole 24, and the number of the lock holes 24 is set to two, and the two lock holes 24 are arranged in parallel, and the lock rod 23 is respectively plugged into the two lock holes 24. The side wall of the lock rod 23 is sleeved with a spring 25, one end of the spring 25 is fixedly connected to the side wall of the lock rod 23, and the other end of the spring 25 is fixedly connected to the inner wall of the lock seat 22.

[0047] When it is necessary to terminate the continuous rotation of the connecting shaft 15, the locking rod 23 is driven to move away from the moving rod 20. The locking rod 23 squeezes the spring 25, and the locking rod 23 disengages from the locking hole 24. At this time, the moving rod 20 is released from the restriction. By driving the moving rod 20 to move away from the main deflector, the main deflector drives the cross bar 17 to move away from the main deflector, so that the cross bar 17 is disengaged from the connecting shaft 15. When the fan body 16 rotates continuously, the fan body 16 no longer drives the connecting shaft 15 to rotate.

[0048] See Figure 6 and Figure 7 For facilitating the adjustment of the guiding angles of the main deflector 6 and the auxiliary deflector 7, one end of the transmission shaft 8 corresponding to the main deflector 6, which is away from the gear 10, also extends into the cavity of the fixed frame 5. A first bevel gear 26 is fixedly sleeved on one end of the transmission shaft 8 away from the gear 10.

[0049] In addition, a rotating member is installed on the fixed frame 5, and the rotating member is used to drive the first bevel gear 26 to rotate. The rotating member is a knob 27. The knob 27 is rotatably installed on the surface of the fixed frame 5. One end of the knob 27 is coaxially and fixedly connected with a rotating rod 28. One end of the rotating rod 28 penetrates and extends into the cavity of the fixed frame 5. A second bevel gear 29 is fixedly sleeved on one end of the rotating rod 28, and the second bevel gear 29 meshes with the first bevel gear 26.

[0050] When the knob 27 is rotated, the knob 27 drives the second bevel gear 29 to rotate through the rotating rod 28. The second bevel gear 29 drives the first bevel gear 26 to rotate. The first bevel gear 26 drives the main deflector 6 to swing through the transmission shaft 8. The main deflector 6 finally drives the auxiliary deflector 7 to swing through the gear 10 and the rack 9, so as to manually change the guiding angles of the main deflector 6 and the auxiliary deflector 7.

[0051] It should be noted that, to improve the safety performance, when using the cooling tower body 1, a ventilation protective cover is added outside the fixed frame 5 to prevent injury caused by accidentally touching the fan body 16.

[0052] The working principle of a cooling tower with a circulating water cooling air guiding device:

[0053] The main function of the cooling tower body 1 is to reduce the water temperature through the heat exchange between water and air, so as to ensure the normal operation of the system. When the exhaust fan 4 in the exhaust duct 3 is started, the dry air outside is sucked into the cooling tower body 1 from the air inlet 2. When the dry air flows through the air inlet 2, the main deflector 6 and multiple auxiliary deflectors 7 guide the dry air, so that the dry air evenly flows into the cooling tower body 1 and exchanges heat with the inclined pipes in the cooling tower body 1.

[0054] When it is necessary to reciprocally swing and adjust the main flow deflector 6 and multiple auxiliary flow deflectors 7, the locking rod 23 is driven to move away from the moving rod 20. The locking rod 23 compresses the spring 25, and the locking rod 23 disengages from the locking hole 24. At this time, the restriction on the moving rod 20 is released. After the restriction on the moving rod 20 is released, the moving rod 20 is driven to move towards the main flow deflector 6. The moving rod 20 drives the cross bar 17 to move towards the main flow deflector 6. At this time, the cross bar 17 is inserted into the square groove 19 through the square block 18. Then, the locking rod 23 is released, the spring 25 releases its elastic force, and drives the locking rod 23 to be inserted into the locking hole 24, and the moving rod 20 is fixed at the current position.

[0055] When dry air is sucked and flows through the air inlet 2, the dry air drives the fan body 16 to rotate. The fan body 16 drives the cross bar 17 to rotate. The cross bar 17 drives the connecting shaft 15 to continuously rotate through the square block 18. The connecting shaft 15 drives the swing pair 11 to rotate. The swing pair 11 drives the swing rod 12 to swing. The swing rod 12 further drives the main flow deflector 6 to reciprocally swing. The main flow deflector 6 finally drives multiple auxiliary flow deflectors 7 to reciprocally swing synchronously. At this time, the dry air is evenly blown towards the inclined pipes in the cooling tower body 1, and the dry air finally discharges from the exhaust duct 3 after heat exchange with the inclined pipes.

[0056] When it is necessary to keep the main flow deflector 6 and the auxiliary flow deflectors 7 stationary at a certain swing angle, repeat driving the locking rod 23 to move away from the moving rod 20 to release the restriction on the moving rod 20. Then, by driving the moving rod 20 to move away from the main flow deflector, the main flow deflector drives the cross bar 17 to move away from the main flow deflector, so that the cross bar 17 is disengaged from the connecting shaft 15. When the fan body 16 continues to rotate, the fan body 16 no longer drives the connecting shaft 15 to rotate. Then, rotate the knob 27. The knob 27 drives the second bevel gear 29 to rotate through the screw rod 28. The second bevel gear 29 drives the first bevel gear 26 to rotate. The first bevel gear 26 drives the main flow deflector 6 to swing through the transmission shaft 8. The main flow deflector 6 finally drives the auxiliary flow deflectors 7 to swing through the gear 10 and the rack 9, so as to manually change the guiding angles of the main flow deflector 6 and the auxiliary flow deflectors 7.

[0057] Embodiment 2: The difference from Embodiment 1 lies in the different structures of the transmission mechanism.

[0058] Specifically, referring to Figure 8 and Figure 9 , the transmission mechanism includes a motor 30. One end of the transmission shaft 8 extends into the cavity of the fixed frame 5. The motor 30 is fixedly installed in the cavity of the fixed frame 5. The output shaft of the motor 30 is fixedly connected to the transmission shaft 8 corresponding to the main flow deflector 6, and the motor 30 is electrically connected to the power supply. Adjacent transmission shafts 8 are respectively drivingly connected with synchronous belt wheels 31.

[0059] When it is necessary to adjust the flow direction of the dry air, the motor 30 is started. The output shaft of the motor 30 drives the transmission shaft 8 to rotate. The transmission shaft 8 drives the main deflector 6 to swing. The main deflector 6 drives the adjacent transmission shafts 8 to rotate synchronously through the synchronous belt pulley 31. The adjacent transmission shafts 8 then drive the corresponding sub-deflectors 7 to swing. At this time, the main deflector 6 and the multiple sub-deflectors 7 swing synchronously, and guide the dry air flowing through the air inlet 2, which is beneficial to improving the stability of the uniform flow of the dry air to the inclined pipes in the cooling tower.

[0060] In summary, under the combined guiding action of the main deflector 6 and the multiple sub-deflectors 7, the flow direction of the dry air flowing through the air inlet 2 is changed, so that the dry air blows uniformly to the inclined pipes, thereby improving the cooling effect of the inclined pipes in the cooling tower.

[0061] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
