Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to an adjustable mist-eliminating cooling tower. Background Art

[0002] The mist elimination cooling tower is a special cooling tower that adds the functions of mist elimination and water saving on the basis of the traditional wet cooling tower. This cooling tower is mainly used in industrial circulating cooling systems and can effectively reduce the generation of water mist while ensuring the cooling effect.

[0003] The method for eliminating the white mist generated during heat dissipation includes providing a rotatable adjustment plate below the spray system to change the contact area between the cooling water and the filler, thereby changing the heat exchange area of the filler and reducing the humidity and temperature of the exhaust air. For example, the prior art Chinese patent publication number "CN115540635A" provides an adjustable mist-eliminating cooling tower, comprising an adjustment plate provided inside the tower body for changing the contact area between the spray liquid and the cooling system, the adjustment plate being located between the spray system and the cooling system; and an adjustment plate provided inside the tower body for driving the A control plate for rotating the adjusting plate is provided in the control plate, and a limit slot for toggling the adjusting plate is provided; by setting a rotatable adjusting plate to steer and speed up the spray liquid, the contact area between the spray liquid and the filler is reduced, the amount of hot and humid air after heat exchange in the filler area is reduced, and the temperature and humidity of the hot and humid air are reduced, which can eliminate the white fog phenomenon at the exhaust port of the induced draft fan. The device does not need to be adjusted in an environment with higher temperature such as summer. For an environment with lower temperature such as winter, it only needs to adjust the control plate to complete the demisting while ensuring the normal operation of the cooling tower. The structure is simple and easy to use.

[0004] However, in actual operation, the inclination angle of the adjustment plate is adjusted by adjusting the operating lever, and manual adjustment requires the operator to go into the tower to make adjustments in person, which is inconvenient to operate in large cooling towers or cooling towers in high-rise buildings. In addition, manual adjustment is difficult to achieve precise and detailed adjustments, which may result in suboptimal cooling efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the inclination angle of the adjustment plate is not easy to operate manually under special circumstances and the adjustment angle has low accuracy, and an adjustable mist elimination cooling tower is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Design an adjustable fog-eliminating cooling tower, including a tower body. Inside the tower body, a packing rack for placing heat exchange packing is fixed, and a spraying device and an adjusting mechanism are arranged between the top of the tower body and the packing rack. The adjusting mechanism is used to change the contact area between the spraying liquid and the packing.

[0008] Among them, the adjusting mechanism includes a plurality of adjusting plates and a control plate. The adjusting plates and the control plate are detachably connected through fixing parts.

[0009] Furthermore, the adjusting mechanism further includes a support frame. The support frame is fixed inside the tower body, and support plates are fixed on both sides of its top. One side of the top of the support frame also has a support auxiliary plate. A chute is formed between the support auxiliary plate and the adjacent support plate, and corresponding through grooves are also opened between them.

[0010] Furthermore, the adjusting plates are rotatably connected between the support plates through rotating shafts integrally formed on both sides, and a connecting rod is arranged on one side of the adjusting plates. The rotating shafts and the connecting rod are movably connected in the through groove on one side. The rotating shafts on the other side of the adjusting plates penetrate through the support plates and are slidably connected with the support plates.

[0011] Furthermore, it also includes a motor. The control plate is slidably connected in the chute, and a through hole matching the connecting rod is opened on its end face. A chute is opened on the top of the control plate. The motor is fixed on the back of the tower body, and its shaft end penetrates through the tower body and is fixedly connected with an eccentric rotating rod.

[0012] Furthermore, the eccentric rotating rod includes a connecting plate. One end of the connecting plate is fixedly connected with the shaft end of the motor, and a rotating rod is fixed at the other end. The free end of the rotating rod is movably connected in the chute.

[0013] Furthermore, the fixing part is a positioning glass bead. One end of the connecting rod extends to the periphery of the control plate, and at least one positioning glass bead is embedded on the side surface. The positioning glass bead abuts against the outer wall of the control plate.

[0014] For an adjustable fog-eliminating cooling tower proposed by the present utility model, the beneficial effects are as follows: The present utility model adjusts the inclination angles of a plurality of adjusting plates simultaneously through the motor and the control plate to change the contact area between the cooling water falling and the packing, thereby changing the heat exchange area of the packing, reducing the humidity and temperature of the discharged air, effectively eliminating white fog, replacing the operation of manually adjusting the angles of the adjusting plates, facilitating the operation and ensuring the accuracy of the adjustment angle at the same time, and the adjusting plates can be disassembled through the fixing parts, facilitating cleaning and avoiding affecting the normal use of the cooling tower.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Refer to Figures 1-4 , an adjustable fog-eliminating cooling tower, including a tower body 1, a packing rack 2 for placing heat exchange packing is fixed inside the tower body 1, and a spraying device 3 and an adjusting mechanism 4 are arranged between the top of the tower body 1 and the packing rack 2, and the adjusting mechanism 4 is used to change the contact area between the spraying liquid and the packing;

[0022] Among them, the adjusting mechanism 4 includes a plurality of adjusting plates 41 and a control plate 42, and the adjusting plates 41 and the control plate 42 are detachably connected through a fixing piece 5.

[0023] It should be added that a water collecting pool for collecting cooling water is provided at the bottom of the tower body 1, and an air inlet is provided on the side surface, and an exhaust fan driven by a motor is fixed at the exhaust port at the top of the tower body 1;

[0024] Specifically, the spraying device 3 includes a water delivery pipe, one end of the water delivery pipe is communicated with a water supply device, and the other end is located inside the tower body 1 and is connected with a plurality of spray heads through a water delivery branch pipe.

[0025] It is worth mentioning that a rotatable adjusting plate 41 is arranged below the spraying device 3 to change the contact area between the cooling water falling and the packing, thereby changing the heat exchange area of the packing, reducing the humidity and temperature of the discharged air to reduce the generation of white fog.

[0026] Furthermore, the adjusting mechanism 4 further includes a support frame 43, which is fixed inside the tower body 1, and support plates 44 are fixed on both sides of its top. One side of the top of the support frame 43 also has a support sub-plate 45, and a chute is formed between the support sub-plate 45 and the adjacent support plate 44, and corresponding through grooves 46 are also provided therebetween.

[0027] Furthermore, the adjusting plate 41 is rotatably connected between the support plates 44 through rotating shafts 411 integrally formed on both sides, and a connecting rod 412 is also provided on one side thereof. The rotating shafts 411 and the connecting rod 412 are movably connected in the through groove 46 on one side. The rotating shafts 411 on the other side of the adjusting plate 41 pass through the support plate 44 and are slidably connected to the support plate 44.

[0028] It is worth mentioning that in an environment with a relatively high external temperature such as in summer, the adjusting plate 41 is in a vertical state, and the distance between two adjacent adjusting plates 41 is at the maximum value, so as to reduce the blockage of the spray liquid by the adjusting plate 41 and make the heat exchange effect of the spray liquid in the packing area within the maximum range.

[0029] Specifically, when demisting is required in an environment with a relatively low external temperature such as in winter, the control plate 42 drives the adjusting plate 41 to rotate, so that the adjusting plate 41 turns to an inclined state. Therefore, the flow rate of the spray liquid passing between the adjusting plates 41 is increased, thereby reducing the contact area between the spray liquid and the packing, and the heat exchange area of the packing is reduced, so that less heat is transferred from the spray liquid to the air.

[0030] More specifically, it further includes a motor 47. The control plate 42 is slidably connected in the chute, and a through hole matching the connecting rod 412 is provided on its end face. A chute 421 is provided on the top of the control plate 42. The motor 47 is fixed on the back of the tower body 1, and its shaft end penetrates through the tower body 1 and is fixedly connected with an eccentric rotating rod 48.

[0031] Generally speaking, the eccentric rotating rod 48 includes a connecting plate 481. One end of the connecting plate 481 is fixedly connected with the shaft end of the motor 47, and a rotating rod 482 is fixed at the other end thereof. The free end of the rotating rod 482 is movably connected in the chute 421.

[0032] In specific operation, the motor 47 drives the eccentric rotating rod 48 to drive the control plate 42 to move. The adjusting plate 41 is rotatably connected to the support frame 43 through the rotating shafts 411, and it rotates in a semi-circular shape under the influence of the control plate 42 driving the connecting rod 412, achieving the adjusting effect.

[0033] Finally, the fixing member 5 is a positioning glass bead. One end of the connecting rod 412 extends to the periphery of the control board 42, and at least one positioning glass bead is embedded on the side surface. The positioning glass bead abuts against the outer wall of the control board 42.

[0034] It should be added that since there is a certain moving space between one side of the adjusting board 41 and the supporting board 44, under normal circumstances, after pressing the positioning glass bead to make it retract, use the moving space to move the adjusting board 41 to disengage the rotating shaft 411 from the control board 42. After disassembling the control board 42, slide the adjusting board 41 and take it out through the through groove.

[0035] Among them, when the other side of the adjusting board 41 abuts against the supporting board 44, it abuts against the control board 42 through the positioning glass bead at the end to achieve a fixing effect and prevent the adjusting board 41 from freely moving out of the through groove.

[0036] Of course, in order to ensure that the control board 42 slides smoothly, a guiding groove and a guiding block are respectively arranged between the two inner side surfaces of the sliding groove and the control board 42. The guiding groove is slidably connected with the guiding block. Moreover, the control board 42 can swing circumferentially in a small range in the sliding groove. Also, the rotating rod 482 and the connecting plate 481 are fixed by a locking bolt. After disassembling the rotating rod 482, the control board 42 is disassembled by sliding.

[0037] Working mode; when working, place the control board 42 in the sliding groove, and then successively place several adjusting boards 41 in the through groove so that the adjusting boards 41 are rotatably connected to the supporting board 44. The connecting rod 412 is rotatably connected to the control board 42, and the positioning glass bead abuts against the outer wall of the control board 42 to achieve a fixing effect.

[0038] After that, the motor 47 drives the control board 42 to move through the eccentric rotating rod 48. While the control board 42 is moving, it drives the connecting rod 412 to make several adjusting boards 41 rotate synchronously and at the same angle.

[0039] Finally, the cooling water is sprayed on the adjusting board 41 through the spraying device 3, and the cooling water flows along the adjacent two sides of the adjusting board 41 and cools through the filler.

[0040] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
