Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, specifically relating to a cooling tower flushing device and a crossflow cooling tower. Background Technology

[0002] A crossflow cooling tower is a device that cools water. Water flows vertically down from the top of the tower, while air flows horizontally through the water-spraying packing, creating a cooling tower where the airflow and water flow are perpendicular.

[0003] After a crossflow cooling tower has been running for a period of time, a lot of dirt will accumulate on the water distribution packing, resulting in scaling, which affects the cooling efficiency of the crossflow cooling tower. Therefore, the water distribution packing needs to be cleaned periodically.

[0004] In existing technologies, the main method is to manually clean the water-spraying packing material monthly. The cleaning steps are as follows: manually turn off the power to the crossflow cooling tower; turn off the inlet and outlet valves, balancing valve, and water supply valve of the crossflow cooling tower; open the drain valve and manually clean with a high-pressure water gun; after rinsing clean, close the drain valve and open the water supply valve to replenish water.

[0005] The disadvantages of manual flushing are: the power supply to the crossflow cooling tower needs to be turned off during flushing to ensure personnel safety, which affects the cooling capacity of the entire refrigeration system (including multiple crossflow cooling towers); and the labor intensity of workers is relatively high during manual flushing. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies in the existing technology by providing a cooling tower flushing device and a crossflow cooling tower. Using this cooling tower flushing device, the water spraying packing can be automatically flushed when the cooling tower is working, thereby reducing the labor intensity of workers.

[0007] In a first aspect, this utility model provides a cooling tower flushing device, which includes a water spraying assembly and a drive assembly. The water spraying assembly includes a first water spray pipe, a second water spray pipe, and a connecting rope. The first and second water spray pipes are respectively arranged laterally on opposite sides of a cooling tower where water-spraying filler is disposed, for spraying cleaning agent onto the corresponding sides of the water-spraying filler. After crossing the top surface of the cooling tower, the connecting rope is connected at both ends to the first and second water spray pipes, respectively. The drive assembly includes a drive component; the drive component is drively connected to the connecting rope, for driving the connecting rope to reciprocate along a first direction and a second direction, so that the first water spray pipe rises and the second water spray pipe falls, or the first water spray pipe falls and the second water spray pipe rises; the first and second directions are two opposite directions extending along the connecting rope.

[0008] In some embodiments, the drive assembly further includes slide rail units. There are two sets of slide rail units, each corresponding to the first water spray pipe and the second water spray pipe respectively. Each set of slide rail units includes two sub-slide rails vertically arranged on the side of the cooling tower. Both the first and second water spray pipes are slidably disposed between the two sub-slide rails on their respective sides.

[0009] In some embodiments, in the slide rail unit, an inverted V-shaped track is formed on the side of each sub-slide rail opposite to the other sub-slide rail, and the inverted V-shaped track is arranged along the extending direction of the sub-slide rail. Rotating wheels are provided at both ends of the first and second water spray pipes, with the wheel surfaces facing the corresponding sub-slide rails; the wheel surfaces of the rotating wheels are formed with V-shaped grooves, which cooperate with the inverted V-shaped track. The rotating wheels are rolled on the inverted V-shaped track via the V-shaped grooves.

[0010] In some embodiments, each sub-slide rail has two inverted V-shaped tracks, which are arranged in parallel. Both ends of the first and second water spray pipes have two rotating wheels, and these two rotating wheels correspond one-to-one with the two inverted V-shaped tracks.

[0011] In some embodiments, the drive assembly further includes two fixed pulleys, which are respectively disposed on both sides of the top surface of the cooling tower and extend outward from the top surface of the cooling tower. The two ends of the connecting rope pass through the two fixed pulleys and are then connected to the first water spray pipe and the second water spray pipe, respectively.

[0012] In some embodiments, the cooling tower flushing device further includes a cleaning agent supply assembly. The cleaning agent supply assembly includes a cleaning agent tank fixed to the top of the cooling tower for storing cleaning agent; both the first spray pipe and the second spray pipe are connected to the cleaning agent tank.

[0013] In some embodiments, the detergent supply assembly further includes a main manifold, a first branch hose, and a second branch hose. The inlet of the main manifold is connected to the detergent tank, the outlet of the main manifold is connected to the first spray pipe via the first branch hose, and the outlet of the main manifold is also connected to the second spray pipe via the second branch hose.

[0014] In some embodiments, the detergent supply assembly further includes a booster pump. The booster pump is disposed on the manifold.

[0015] In some embodiments, the manifold is a rigid pipe.

[0016] Secondly, this utility model embodiment also provides a crossflow cooling tower, which includes a cooling tower body and the cooling tower flushing device described in the first aspect. The cooling tower body includes a fan and water-spraying packing.

[0017] The crossflow cooling tower provided in this embodiment can automatically flush the entire water-spraying packing material during operation, thus maintaining the crossflow cooling tower's ability to continuously cool water and improving its self-cleaning capability. Furthermore, the flushing of the water-spraying packing material by the cooling tower flushing device requires no manual labor, reducing worker workload. Therefore, the cleaning frequency of the water-spraying packing material in the crossflow cooling tower can be increased, thereby maintaining a high level of cleanliness, alleviating scaling, extending the service life of the packing material, and improving the cooling efficiency of the crossflow cooling tower.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1:

[0025] like Figure 1 As shown, this utility model embodiment provides a cooling tower flushing device, which is applied to the flushing process of a crossflow cooling tower.

[0026] like Figure 1As shown, the cooling tower flushing device includes a water spray assembly and a drive assembly. The water spray assembly includes a first water spray pipe 1, a second water spray pipe, and a connecting rope 3. The first water spray pipe 1 and the second water spray pipe are respectively arranged laterally on opposite sides of the cooling tower where water-spraying packing 4 is installed, for spraying cleaning agent onto the corresponding sides of the water-spraying packing 4. After crossing the top surface of the cooling tower, the connecting rope 3 is connected at both ends to the first water spray pipe 1 and the second water spray pipe, respectively. The drive assembly includes a drive component 5; the drive component 5 is drively connected to the connecting rope 3, for driving the connecting rope 3 to reciprocate along a first direction and a second direction, so that the first water spray pipe 1 rises and the second water spray pipe falls, or the first water spray pipe 1 falls and the second water spray pipe rises. The aforementioned first direction and second direction are two opposite directions extending along the connecting rope 3.

[0027] For example, Figure 1 The cooling tower in this design is a crossflow cooling tower. Water spray packing 4 is installed on both the front and rear sides of this type of cooling tower, while the left and right sides are enclosed shells. In this case, the first water spray pipe 1 is located on the front side of the cooling tower, and the second water spray pipe is located on the rear side.

[0028] For example, the first water spray pipe 1 and the second water spray pipe can have exactly the same structure.

[0029] It can be different, as long as it allows spraying cleaning agent onto the water-spraying filler 4.

[0030] For example, the cleaning agent can be water or an aqueous solution containing detergent (e.g., surfactant).

[0031] like Figure 2 As shown, the first water spray pipe 1 is equipped with an inlet 702 and multiple nozzles 701. The inlet 702 is connected to an external cleaning agent delivery pipe. High-pressure (e.g., 20 bar) cleaning agent enters the first water spray pipe 1 through the inlet 702 and is sprayed out from the multiple nozzles 701. All nozzles 701 face the corresponding side of the water spray filler 4. In this embodiment, the structure of the second water spray pipe is exactly the same as that of the first water spray pipe 1.

[0032] That is, Figure 1 In the process, the nozzle 701 on the first water spray pipe 1 sprays cleaning agent towards the front water spraying packing 4 to clean the front water spraying packing 4 of the cooling tower; the nozzle 701 on the second water spray pipe sprays cleaning agent towards the rear water spraying packing 4 to clean the rear water spraying packing 4 of the cooling tower.

[0033] For example, the lengths of the first water spray pipe 1 and the second water spray pipe are greater than the width of the water spraying filler 4, so that the cleaning agent sprayed from the first water spray pipe 1 and the second water spray pipe can clean the entire water spraying filler 4.

[0034] For example, the connecting rope 3 can be a steel wire rope.

[0035] There can be one connecting rope 3, with its two ends connected to the center of gravity of the first water spray pipe 1 and the second water spray pipe respectively, so that the connecting rope 3 provides tension to the first water spray pipe 1 and the second water spray pipe, thereby enabling the first water spray pipe 1 and the second water spray pipe to remain stable.

[0036] The number of connecting ropes 3 can also be two, with the two connecting ropes 3 respectively set at... Figure 1 On the left and right sides of the top surface of the central cooling tower, two connecting ropes 3 can be simultaneously connected to both ends of the first and second water spray pipes, respectively, to apply tension to both ends of the first and second water spray pipes simultaneously, thereby improving the stability of the first and second water spray pipes. Combined with... Figure 2 and Figure 3 Both ends of the first water spray pipe 1 and the second water spray pipe are equipped with connecting rods 13, and the connecting rope 3 is connected to the connecting rods 13.

[0037] For example, the driving component 5 can be a motor, with a pulley mounted on the motor shaft. The connecting rope 3 is pressed onto the pulley. When the motor rotates in both directions, the pulley can drive the connecting rope 3 to reciprocate along a first direction and a second direction. Here, the first direction and the second direction are two opposite directions.

[0038] When there are two connecting ropes 3, there are also two driving components 5. The two driving components 5 are set one-to-one with the two connecting ropes 3, and the two driving components 5 rotate synchronously to drive the two connecting ropes 3 to move synchronously.

[0039] This is understandable, because the length of connecting rope 3 is constant; therefore, as... Figure 1 As shown, when the first water spray pipe 1 rises, the second water spray pipe falls; when the first water spray pipe 1 falls, the second water spray pipe rises.

[0040] For example, the first direction is Figure 1 The direction backwards in the middle, the second direction is Figure 1 The forward direction in the middle. For example... Figure 1 As shown, when the driving component 5 drives the connecting rope 3 to move along the first direction, the connecting rope 3 drives the first water spray pipe 1 to move upward along the front side of the cooling tower. At this time, the second water spray pipe moves downward along the rear side of the cooling tower under its own weight and the tension of the connecting rope 3. When the driving component 5 drives the connecting rope 3 to move along the second direction, the connecting rope 3 drives the second water spray pipe to move upward along the rear side of the cooling tower. At this time, the first water spray pipe 1 moves downward along the front side of the cooling tower under its own weight and the tension of the connecting rope 3.

[0041] Therefore, by adjusting the rotation direction of the drive component 5, the first and second water spray pipes can be moved up and down repeatedly via the connecting rope 3 to repeatedly flush the entire water-spraying packing 4. Furthermore, no manual intervention is required when the cooling tower flushing device flushes the water-spraying packing 4, thus reducing the labor intensity of workers. Also, there is no need to shut off the cooling tower's power supply during flushing, allowing the water-spraying packing 4 to be flushed while the cooling tower is operating normally, ensuring the cooling tower's continuous operation.

[0042] Therefore, the cooling tower flushing device provided in this embodiment of the present invention, by setting a first water spray pipe 1 and a second water spray pipe, and setting the first water spray pipe 1 and the second water spray pipe horizontally on opposite sides of the cooling tower where the water-spraying packing 4 is set, allows the first water spray pipe 1 and the second water spray pipe to spray cleaning agent onto the water-spraying packing 4 on the corresponding sides, and the water-spraying packing 4 can be flushed through the first water spray pipe 1 and the second water spray pipe; by setting a connecting rope 3, and setting the connecting rope 3 to connect the first water spray pipe 1 and the second water spray pipe at both ends after crossing the top surface of the cooling tower, the movement of the connecting rope 3 can drive one of the first water spray pipe 1 and the second water spray pipe to rise while the other falls; by setting a driving component 5, the connecting rope 3 can be driven to move back and forth along the first direction and the second direction, thereby causing the connecting rope 3 to drive the first water spray pipe 1 and the second water spray pipe to move up and down repeatedly to flush the entire water-spraying packing 4. Furthermore, no manual intervention is required when the cooling tower flushing device flushes the water-spraying packing 4, thus reducing the labor intensity of workers. It is also not necessary to turn off the power of the cooling tower during flushing, so the water-spraying packing 4 can be flushed while the cooling tower is working normally, ensuring the continuous operation of the cooling tower.

[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the drive assembly also includes slide rail units. There are two sets of slide rail units, corresponding to the first water spray pipe 1 and the second water spray pipe respectively. Each set of slide rail units includes two sub-slide rails 6 vertically mounted on the side of the cooling tower. The first water spray pipe 1 and the second water spray pipe are slidably mounted between the two sub-slide rails 6 on their respective sides.

[0044] For example, such as Figure 1 As shown, two sub-rails 6 corresponding to the first water spray pipe 1 are set on two vertical sides at the front of the cooling tower, allowing the first water spray pipe 1 to move up and down along these two sub-rails 6. Two sub-rails 6 corresponding to the second water spray pipe are set on two sides at the rear of the cooling tower, allowing the second water spray pipe to move up and down along these two sub-rails 6.

[0045] With the above settings, the movement direction of the first water spray pipe 1 and the second water spray pipe can be guided by the two sub-slide rails 6 in each slide rail unit.

[0046] In some embodiments, combined with Figure 1 and Figure 3 In the slide rail unit, each sub-slide rail 6 has an inverted V-shaped track on the side opposite to the other sub-slide rail 6, and the inverted V-shaped track is arranged along the extension direction of the sub-slide rail 6. Rotating wheels 7 are provided at both ends of the first and second water spray pipes, with the wheel surface of the rotating wheel 7 facing the corresponding end of the sub-slide rail 6. The wheel surface of the rotating wheel 7 has a V-shaped groove, which cooperates with the inverted V-shaped track. The rotating wheel 7 rolls along the inverted V-shaped track via the V-shaped groove.

[0047] For example, such as Figure 3 As shown, the inverted V-shaped track is an inverted V-shaped protrusion formed on the sub-slide rail 6.

[0048] For example, such as Figure 2 and Figure 3 As shown, the connecting rod 13 is horizontally positioned and perpendicular to the extension direction of the sub-slide rail 6, and the rotating wheel 7 is rotatably mounted on the connecting rod 13.

[0049] For example, a bearing is also provided between the rotating wheel 7 and the connecting rod 13 to reduce the resistance when the rotating wheel 7 rotates.

[0050] For example, the rotating wheel 7 is made of metal, such as stainless steel.

[0051] By making the V-shaped groove on the surface of the rotating wheel 7 cooperate with the inverted V-shaped track, the rotating wheel 7 can be locked on the inverted V-shaped track. The inverted V-shaped track can guide the rotating wheel 7, thereby guiding the up and down movement of the first water spray pipe 1 and the second water spray pipe.

[0052] In some embodiments, in each sub-slide rail 6, such as Figure 2 and Figure 3 As shown, there are two inverted V-shaped tracks, which are arranged in parallel. There are two rotating wheels 7 at each end of the first and second water spray pipes, and each of the two rotating wheels 7 corresponds to one of the two inverted V-shaped tracks.

[0053] like Figure 2 and Figure 3 As shown, the two rotating wheels 7 are positioned close to both ends of the connecting rod 13, and the distance between the two rotating wheels 7 is the same as the distance between the two inverted V-shaped tracks, so that each rotating wheel 7 can be locked in the corresponding inverted V-shaped track.

[0054] With the above setup, the up-and-down movement of the first water spray pipe 1 and the second water spray pipe can be guided by two inverted V-shaped tracks and two rotating wheels 7, thereby improving the stability of the first water spray pipe 1 and the second water spray pipe when moving up and down.

[0055] In some embodiments, combined with Figure 1 and Figure 3 The drive assembly also includes two fixed pulleys 8, which are respectively located on both sides of the top surface of the cooling tower and extend outward from the top surface of the cooling tower. The two ends of the connecting rope 3 pass through the two fixed pulleys 8 and are connected to the first water spray pipe 1 and the second water spray pipe respectively.

[0056] For example, such as Figure 3 As shown, the fixed pulley 8 is rotatably mounted on the support frame, which is fixed to the top of the cooling tower by screws. The connecting rope 3 is located within the rotation plane of the fixed pulley 8.

[0057] With the above configuration, the horizontal tension applied by the drive component 5 to the connecting rope 3 is converted into a vertical tension on the first water spray pipe 1 and the second water spray pipe after passing through the fixed pulley 8, so as to pull the first water spray pipe 1 and the second water spray pipe to move up and down.

[0058] In some embodiments, such as Figure 1 and Figure 4 As shown, the cooling tower flushing device also includes a cleaning agent supply assembly. The cleaning agent supply assembly includes a cleaning agent tank 9, which is fixed to the top of the cooling tower and used to store cleaning agent. Both the first spray pipe 1 and the second spray pipe are connected to the cleaning agent tank 9.

[0059] For example, the cleaning agent tank 9 is fixed to the top surface of the cooling tower by bolts.

[0060] With the above setup, the cleaning agent can be stored in the cleaning agent tank 9 in advance, so that the cleaning agent can be continuously supplied to the first spray pipe 1 and the second spray pipe through the cleaning agent tank 9.

[0061] In some embodiments, such as Figure 1 As shown, the detergent supply assembly also includes a main manifold 10, a first branch hose 11, and a second branch hose. The inlet of the main manifold 10 is connected to the detergent tank 9, the outlet of the main manifold 10 is connected to the first spray pipe 1 through the first branch hose 11, and the outlet of the main manifold 10 is also connected to the second spray pipe through the second branch hose.

[0062] For example, such as Figure 1 As shown, the pipe located on the top surface of the cooling tower is the main manifold 10, which is fixed to the top surface of the cooling tower. The pipe between the main manifold 10 and the first spray pipe 1 is the first branch hose 11, and the pipe between the main manifold 10 and the second spray pipe is the second branch hose.

[0063] The materials of the first diversion hose 11 and the second diversion hose can be polyethylene, polypropylene, etc.

[0064] Combination Figure 1 Both the first branch hose 11 and the second branch hose are hoses, so they can deform. Thus, when the vertical positions of the first branch hose 11 and the second branch hose change, they can ensure that the cleaning agent in the main manifold 10 is delivered to the first spray pipe 1 and the second spray pipe through their own deformation.

[0065] In some embodiments, such as Figure 1 and Figure 4 As shown, the cleaning agent supply assembly also includes a booster pump 12. The booster pump 12 is mounted on the manifold 10.

[0066] For example, booster pump 12 can be an existing centrifugal booster pump.

[0067] The booster pump 12 can pressurize the cleaning agent in the manifold 10 so that the cleaning agent can be sprayed from the nozzles 701 of the first and second spray pipes onto the water spraying filler 4, thereby achieving a flushing effect on the water spraying filler 4.

[0068] In some embodiments, the manifold 10 is a rigid pipe.

[0069] For example, the manifold 10 can be a steel pipe.

[0070] The above configuration reduces the deformation of the manifold 10, making it easier to fix the manifold 10 to the top surface of the cooling tower. Furthermore, the rigid pipe is generally able to withstand higher water pressure and flow rate, facilitating the simultaneous delivery of high-pressure (e.g., 20 bar) cleaning agent to both the first and second spray pipes.

[0071] Understandably, this cooling tower flushing device can also be applied in other scenarios, such as cleaning the outer surfaces of the left and right sides of the cooling tower by adjusting the position of the cooling tower flushing device.

[0072] Example 2:

[0073] This utility model embodiment also provides a crossflow cooling tower, which can be used in a cooling system for cooling communication equipment rooms. For example... Figure 1 As shown, the crossflow cooling tower includes a cooling tower body and the cooling tower flushing device in Example 1. The cooling tower body includes a fan 2 and water-spraying packing 4.

[0074] like Figure 1 As shown, the cooling tower body also includes a shell, and the fan 2 and water-spraying packing 4 are disposed inside the shell. Both the fan 2 and the water-spraying packing 4 are existing devices.

[0075] The cooling tower flushing device can flush the entire water-spreading packing 4 while the crossflow cooling tower is in operation. Therefore, it maintains the continuous cooling capacity of the crossflow cooling tower and improves its self-cleaning ability. Furthermore, the flushing of the water-spreading packing 4 requires no manual labor, reducing worker workload. This allows for increased cleaning frequency of the water-spreading packing 4 in the crossflow cooling tower, maintaining a high level of cleanliness, mitigating scaling, extending its service life, and improving the cooling efficiency of the crossflow cooling tower.

[0076] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
