Description

Technical Field

[0001] This utility model relates to a cooling tower, specifically to an adjustable water collector and a cooling tower. Background Technology

[0002] In some engineering projects, the height of cooling towers is limited. In particular, when applying packing modules to the renovation of old towers, the height of the old towers is fixed, and the design space is very limited. In water-saving and defogging cooling towers, the rotating valve plates used to close and open the cold and hot passages also need to occupy a certain height inside the tower. In addition, the height occupied by the water collector adds to the great challenges of construction.

[0003] Figure 6 The diagram shows the structure of a traditional water collector, which is used to recover water droplets carried by rising air, thus saving water and protecting the environment. This component is also essential in cooling towers. Utility Model Content

[0004] In view of the above-mentioned prior art, this utility model provides an adjustable water collector that combines the functions of a water collector and a rotating valve plate, and can be used in water-saving and defogging cooling towers. The adjustable water collector includes:

[0005] The flow path through which the airflow passes within the cooling tower; and

[0006] The water collection plate is supported as a rotatable water collection plate, which allows the adjustable water collector to have a first state where the flow path is open and a second state where the flow path is closed.

[0007] The water-collecting plate has a wavy, curved cross-section.

[0008] Furthermore, the adjustable water collector has a frame, one end of which forms an inlet for airflow to enter and the other end forms an outlet for airflow to exit.

[0009] The water collection plate is rotatably connected to the frame.

[0010] Furthermore, there are multiple water collection plates, which are arranged in parallel.

[0011] In the first state, a tortuous airflow path is formed between two adjacent water collection plates;

[0012] In the second state, multiple water-collecting plates are connected in sequence to close the airflow passage.

[0013] Furthermore, in the second state, the lower surface of one of the two adjacent water-collecting plates overlaps with the upper surface of the other.

[0014] Furthermore, in the second state, the wavy lower surface of one of the two adjacent water-collecting plates is in contact with the wavy upper surface of the other.

[0015] Furthermore, the water collection plate has a first extension and a second extension connected to the first extension, and there is an included angle between the first extension and the second extension;

[0016] A pivot is provided at the connection between the first extension and the second extension;

[0017] The water collection plate is oscillatingly connected to the frame via the pivot.

[0018] Furthermore, the adjustable water collector also includes a drive plate and connecting rods corresponding one-to-one with the rotating shaft.

[0019] One end of the connecting rod is fixedly connected to the rotating shaft, and the other end is pivotally connected to the drive plate.

[0020] An embodiment of this utility model also provides a water-saving and defogging cooling tower, which has the adjustable water collector described in any of the above-mentioned embodiments.

[0021] Based on the aforementioned adjustable water collector, the adjustable water collector of this utility model can open or close the airflow path in the water spraying space. When it is open, it can collect water, and when it is closed, it can cut off the upward airflow path in the water spraying space. Furthermore, the adjustable water collector can also be adjusted to a suitable opening degree to adapt to changes in climate conditions and achieve the optimal water-saving and fog-eliminating effect.

[0028] In the water-saving and defogging cooling tower, the packing module has alternating stacked first and second flow paths. The first flow path, for example, can be used to circulate dry, cold air, while the second flow path is used for spraying hot water. The hot water in the second flow path also comes into contact with the air in the second flow path, exchanging heat to form humid, hot air. Thus, the dry, cold air in the first flow path and the hot water in the second flow path exchange heat through the inter-wall, forming dry, hot air at the upper outlet of the first flow path. This dry, hot air mixes with the humid, hot air flowing out of the second flow path, reducing the saturation of the humid, hot air, thereby achieving water saving and defogging effects.

[0029] Specifically, such as Figure 1 As shown, in the cooling tower 2000, the first upper opening G of the first flow path of the packing module 1000 is located in the middle of the width direction of the packing module 1000, while the second upper openings W1 and W2 of the second flow path are located on both sides of the width direction of the packing module 1000.

[0030] The partition 2005 extends along the stacking direction, and its lower end corresponds to the connection point of the first upper opening G and the second upper openings W1 and W2 in the width direction of the packing module 1000. The valve plate 2009 is used to close the upward passage of humid and hot air in the water spray channel, so that when the valve plate 2009 is closed, only heat exchange occurs within the partition wall of the packing module 1000, and no humid and hot air is generated. The water collector 2010 is used to collect water droplets carried in the upward air, playing a role in water conservation and environmental protection; the function achieved by this component is also essential in cooling towers.

[0031] However, in some engineering projects, the height of the cooling tower is limited. This is especially true in the renovation of older towers where the height is fixed and the internal design space is very limited, limiting the use of rotatable valve plates (such as those in 2009) for opening and closing the water spray channels. Figure 1 As shown, the tower occupies a certain height inside the tower. In addition, the height occupied by the water collector makes the construction of converting a conventional cooling tower into a water-saving and defogging cooling tower extremely challenging.

[0032] To address the issue of limited height within the tower, the inventors of this invention have made bold innovations and improvements: combining the functions of the water collector 2010 and the valve plate 2009, which not only realizes the original function of the water collector but also the opening and closing function of the valve. Furthermore, it can adjust the opening degree of the water collector according to different parameters such as climate and water temperature, thereby optimizing the water-saving and mist-eliminating effect.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 2As shown, the cooling tower 6000 can adopt the structure of the packing module 1000 described above. Multiple parallel baffles 2005 are provided on the upper side of the cooling tower 6000, dividing the upper space of the cooling tower 6000 into alternating interval spaces 2005a and 2005b. Interval space 2005a communicates with the first upper opening G of the packing module 1000, and interval space 2005b communicates with the second upper openings W1 and W2 of the packing module 1000. In this embodiment, for example, hot water can be sprayed into interval space 2005a to form a water-spraying space (hereinafter referred to as 2005a); while no water is sprayed into interval space 2005b, forming an air-entraining space (hereinafter referred to as 2005b).

[0035] Correspondingly, a water collector 2010 and an adjustable water collector 600 are installed at the upper end of the partition 2005. Specifically, the adjustable water collector is installed at the upper end of the water spraying space 2005a, and the conventional water collector 2010 is installed at the upper end of the air venting space 2005b.

[0036] Specifically, the adjustable water collector 600 has a flow path 660 through which airflow passes within the cooling tower and a movable water collection plate 620. The water collection plate 620 allows the adjustable water collector 600 to have a first state where the flow path 660 is open and a second state where the flow path 660 is closed.

[0037] The adjustable water collector 600 of this embodiment is installed on the upper side of the water spray space of the cooling tower. When the adjustable water collector 600 is in the first state, it can play the role of collecting water; and when the adjustable water collector 600 is in the second state, it can close the water spray space where it is located and block the passage of hot and humid air in the water spray space.

[0038] In some embodiments, such as Figure 4 As shown, the adjustable water collector 600 includes a frame 610, the interior of which forms a receiving space 611. The lower end of the frame 610 forms an inlet for airflow, and the upper end forms an outlet for airflow. Multiple water-collecting plates 620 are arranged in the receiving space 611. Each water-collecting plate 620 has a curved cross-section and extends along the width direction of the adjustable water collector 600 (i.e., the length direction of the water-collecting plate 620). Figure 4 Extending in a direction perpendicular to the paper surface, for example having a curved cross-section, it serves to collect water droplets. In this embodiment, the water collection plate 620 is rotatably connected to the frame 610.

[0039] In this embodiment, there are multiple water collection plates 620, and the multiple water collection plates 620 are arranged in parallel; in the first state, a tortuous airflow passage 661 is formed between two adjacent water collection plates 620, and the multiple airflow passages 661 form the flow path 660 of the adjustable water collector 600. In the second state, as... Figure 5 As shown, multiple water collection plates 620 are connected in sequence to close the airflow passage 661.

[0040] The aforementioned tortuous airflow passage 661 can be formed in various ways, such as by setting a convex and concave structure on the water collection plate 620, or by setting the water collection plate 620 as a repeatedly bent structure, etc.

[0041] In some embodiments, such as Figure 4 As shown, the water collection plate 620 has a first extension 621 and a second extension 622, with an included angle between them, for example, an obtuse angle. A rotating shaft 630 is fixed at the connection between the first extension 621 and the second extension 622, and the rotating shaft 630 is rotatably connected to the frame 610. The lower end of the connecting rod 640 is fixedly connected to the rotating shaft 630, and the connecting rod 640 can drive the water collection plate 620 to rotate. The upper end of the connecting rod 640 is pivotally connected to the drive plate 650, so that the drive plate 650 can drive multiple water collection plates 620 to rotate synchronously, thereby switching the adjustable water collector 600 between a first state and a second state.

[0042] Figure 4 The adjustable water collector 600 is shown in the open state (i.e., the first state), while Figure 5 This indicates that the adjustable water collector is in the off state (i.e., the second state).

[0043] Will Figure 5 The water collection plate 620 shown is rotated counterclockwise to form a shape like... Figure 5 As shown, the right-side water-collecting plate 620 overlaps the upper side of the adjacent left-side water-collecting plate 620, and so on, to achieve the closed state of the adjustable water collector. In the closed state, the lower curved surface on the right-side water-collecting plate 620 engages with the upper curved surface of the left-side water-collecting plate 620, improving the sealing effect when the adjustable water collector is closed.

[0044] To improve the strength of the water collection plate 620, a reinforcing part 623 is provided on the water collection plate 620. The reinforcing part 623 has a groove that is adapted to the bending cross section of the water collection plate 620 to accommodate the end of the water collection plate 620.

[0045] Based on the above structure, the cooling tower 6000 has multiple operating modes:

[0046] First working mode: such as Figure 2As shown, both the water spraying space 2005a and the air extraction space 2005b are in the water spraying state. At this time, the adjustable water collector 600 is in the open state, and together with the water collector 2010, it plays the role of water collection.

[0047] Second operating mode: The nozzles in the water spraying space 2005a are turned on, and the nozzles in the water spraying space 2005b are turned off. At this time, the cold air flowing from the lower part of the cooling tower contacts and exchanges heat with the hot water in the flow path of the corresponding packing module in the water spraying space 2005a, forming saturated hot air; while in the non-spraying space, the air flowing out of the corresponding packing module exchanges heat with the hot water through the walls between the packing plates, forming unsaturated hot air with low moisture content. At this time, the adjustable water collector 600 is in the open state to collect water from the saturated hot air.

[0048] The third working mode, based on the second working mode, shuts off the adjustable water collector 600, thereby allowing heat exchange between the cold air and the hot water wall in the packing module 1000. This third working mode has the best water-saving and anti-fogging effect and is suitable for very cold weather conditions.

[0049] In the fourth working mode, when the nozzles in the air intake space 2005b are turned on and the nozzles in the water spraying space 2005a are turned off, the opening of the adjustable water collector 600 can be adjusted to a half-open and half-closed state, or adjusted to a suitable opening based on the climate conditions, thereby adjusting the air flow in the corresponding packing module flow path through the water spraying flow path, and thus optimizing the water-saving and defogging effect.

[0050] In addition, the aforementioned adjustable water collector 600 can be installed at the upper end of both the water spraying space 2005a and the air intake space 2005b, thereby enabling the airflow of the two flow paths to be adjustable and to be turned off / on.

[0051] The aforementioned adjustable water collector 600 can also be used in cooling towers with other water-saving and defogging packing modules to achieve adjustable opening of the water spray space and / or air intake space and water collection.

[0052] The adjustable water collector can also have other structures, such as partially fixed water collection plates 620, with a rotatable water collection plate 620 positioned between two fixed water collection plates 620, thereby achieving a similar function. Alternatively, all or part of the water collection plates 620 can be slidably connected to the frame 610 to achieve a similar function.

[0053] The preferred embodiment of the device of this utility model has been described in detail above. However, those skilled in the art can make various modifications, alterations, and combinations based on this description, and all such modifications, alterations, and combinations fall within the protection scope of the claims of this application.
