Description

Technical Field

[0001] This application relates to the field of cooling tower technology, and more particularly to a cooling tower. Background Technology

[0002] Currently, cooling towers primarily use water as a circulating coolant to absorb heat from the system and release it into the atmosphere, thereby lowering the system's temperature. However, during use, due to the deposition of impurities and microorganisms in the water, sludge inevitably forms inside the cooling tower. This sludge adheres to various parts of the tower, including the packing, nozzles, and tower valves.

[0003] To remove this sludge, high-pressure water jets or other tools are typically used to flush the inside of the cooling tower. However, while this method can remove the sludge, the strong impact often causes it to flow and spread further. More problematic is that the water level in the cooling water tank is usually still high during cleaning, making it easy for sludge to flow into the tank, affecting the water quality and increasing the difficulty of the cleaning process. Utility Model Content

[0004] This application provides a cooling tower that solves the problem that sludge easily flows into the cold water pool when cleaning the sludge inside the tower.

[0005] This application provides a cooling tower, which includes a tower body, multiple guide plates, and multiple support members. The tower body has a packing layer inside, and a cold water pool is formed at the bottom of the tower body. One end of each guide plate is rotatably installed inside the tower body, and each guide plate is located between the packing layer and the cold water pool. At least one support member is disposed opposite to one guide plate, and one end of each support member is rotatably installed inside the tower body. The other end of each support member supports one guide plate, so that the multiple guide plates surround and form a guide shroud above the cold water pool.

[0006] Optionally, in some embodiments, the cooling tower further includes multiple water outlet pipes disposed on the outer wall of the tower body, and the tower body is provided with multiple water outlets, all of which are located between the packing layer and the cold water pool. Each water outlet pipe communicates with the interior of the tower body through one of the water outlets. One end of each guide plate rotates to the corresponding water outlet, so that the guide shroud formed by the multiple guide plates is formed, and the guide shroud is used to guide water out of the tower body from the water outlet pipes.

[0007] Optionally, in some embodiments, a water-blocking component is provided on the inner sidewall of the tower body. The water-blocking component protrudes towards the central axis of the tower body and is located between the water outlet and the packing layer.

[0008] Optionally, in some embodiments, the water-blocking member is inclined relative to the inner wall of the tower body toward the direction of the cold water pool.

[0009] Optionally, in some embodiments, the cooling tower further includes a water supply pipe, the water supply pipe being partially located inside the tower body, and a plurality of the guide plates being arranged sequentially along the circumferential direction of the water supply pipe, with one end of each guide plate rotatably mounted on the water supply pipe, and one end of a plurality of the support members being rotatably mounted on the water supply pipe.

[0010] Optionally, in some embodiments, the cooling tower further includes a spray structure, one end of the water supply pipe is connected to an external water source of the tower body, and the other end of the water supply pipe extends above the packing layer and is connected to the spray structure. The spray structure includes a plurality of high-pressure nozzles, which are arranged opposite to the packing layer.

[0011] Optionally, in some embodiments, a reset member is provided at the rotatable mounting point of the support member, the reset member being used to drive the support member to reset.

[0012] Optionally, in some embodiments, the reset element includes a torsion spring sleeved on a pivot between the support and the tower body, with both ends of the torsion spring abutting against the support and the tower body respectively; and / or, the reset element includes an elastic rope, one end of which is connected to the support and the other end of which is connected to the tower body.

[0013] Optionally, in some embodiments, the guide plate is provided with a slot, and one end of the support member is engaged in the slot to support the guide plate.

[0014] Optionally, in some embodiments, the side of the guide plate is provided with a water-absorbing element, and when the plurality of guide plates are rotated to form the guide shroud, the water-absorbing element abuts against the inner wall of the tower body.

[0015] The technical effect of the cooling tower provided in this application embodiment is as follows: By setting multiple guide plates inside the tower body, with each guide plate located between the packing layer and the cold water pool, and one end of each guide plate rotatably installed inside the tower body, and multiple support members rotatably installed inside the tower body, when it is necessary to clean the sludge inside the tower body, the multiple guide plates can be rotated, and the multiple support members can be respectively supported below the multiple guide plates, so that the multiple guide plates form a guide shroud. The guide shroud is located between the cold water pool and the packing layer, and is located directly above the cold water pool. The sludge washed down from the packing layer by a high-pressure water gun will be blocked on the guide shroud, making it difficult for the sludge to flow into the cold water pool, thereby reducing the impact of waste sludge on the cold water pool and reducing the difficulty of cleaning work.

[0029] Please see Figures 1 to 3 The present application provides a cooling tower 100, which may include a tower body 1, multiple guide plates 4 and multiple support members 5.

[0030] Specifically, the tower body 1 of the cooling tower 100, serving as its core outer shell, typically adopts a cylindrical structure. This structure not only provides stable support but also ensures the full utilization of the tower body 1's enclosure function. Inside the tower body 1, a packing layer 2 is installed. The packing layer 2 is composed of a series of layered materials, providing the largest possible heat exchange area for water and air, promoting heat transfer and evaporative cooling, and ensuring the efficient operation of the cooling tower 100. A cold water pool 3 is formed at the bottom of the tower body 1. The cold water pool 3 is responsible for collecting and storing the cooled water, ensuring the continuous cooling process. The packing layer 2 and the cold water pool 3 work together to complete the cooling task of the cooling tower 100.

[0031] Multiple ventilation holes are distributed on the side wall of the tower body 1. These ventilation holes are closely arranged and together form the ventilation structure of the cooling tower 100. The function of the ventilation structure is not only to provide the necessary air circulation inside the tower body 1, but also to effectively guide the airflow and ensure that the air can flow evenly and efficiently through the packing layer 2, thereby improving the cooling effect. A fan is also installed at the top of the tower body 1. The fan generates a strong airflow by rotating, which draws fresh air from the outside into the cooling tower 100. When this air flows through the packing layer 2, it undergoes full heat exchange with the hot water, removes the heat, and is then discharged outside the tower through the ventilation holes. The fan greatly enhances the air circulation inside the cooling tower 100, which significantly improves the cooling efficiency.

[0032] Multiple guide plates 4 can be disposed inside the tower body 1, and each guide plate 4 is located between the packing layer 2 and the cold water pool 3. One end of each guide plate 4 can be rotatably installed inside the tower body 1, so that each guide plate 4 can rotate relative to the tower body 1. Similarly, multiple support members 5 can also be disposed between the packing layer 2 and the cold water pool 3, and at least one support member 5 is disposed opposite to one guide plate 4, and one end of each support member 5 is rotatably installed inside the tower body 1.

[0033] Combination Figure 2 When it is necessary to clean the sludge inside the tower body 1, multiple guide plates 4 can be rotated to an inclined position relative to the vertical direction, and multiple support members 5 can be placed under the multiple guide plates 4 respectively, so that the multiple guide plates 4 can be enclosed to form a guide hood. In this embodiment, two adjacent guide plates 4 are connected together by a waterproof cloth. After the multiple guide plates 4 are unfolded, they can form a guide hood with the waterproof cloth. The shape of the guide hood is the same as the inner contour shape of the tower body 1, and the size of the guide hood is the same as the inner contour shape of the tower body 1, so that the guide hood can be placed directly above the cold water pool 3. The sludge washed down from the packing layer 2 by the high-pressure water gun will be blocked on the guide hood, so that the sludge is not easy to flow into the cold water pool 3, which can reduce the impact of waste sludge on the cold water pool 3 and reduce the difficulty of cleaning work.

[0034] Preferably, the guide shroud formed by multiple guide plates 4 has a structure similar to a trumpet, and the larger end of the trumpet-shaped guide shroud is set towards the direction close to the cold water pool 3, which can better collect and block sludge and prevent sludge from flowing into the cold water pool 3.

[0035] Combination Figure 3 When the cooling tower 100 is in normal use, these guide plates 4 can be rotated to be set in a vertical direction, which will not obstruct the water flow between the packing layer 2 and the cold water pool 3, ensuring that the cooling water can flow smoothly into the cold water pool 3 and maintain the normal operation of the cooling tower 100.

[0036] Please see Figures 1 to 3 In some embodiments, the cooling tower 100 may also include a plurality of water outlet pipes 6. Specifically, the plurality of water outlet pipes 6 may be disposed on the outer side wall of the tower body 1, and the plurality of water outlet pipes 6 may be arranged sequentially at intervals along the circumferential direction of the tower body 1.

[0037] Meanwhile, the side wall of the tower body 1 is provided with an outlet 11 corresponding to the water outlet pipe 6. Multiple outlets 11 are also arranged sequentially at intervals along the circumference of the tower body 1, and multiple outlets 11 are located between the packing layer 2 and the cold water pool 3, so that each water outlet pipe 6 can be connected to the interior of the tower body 1 through an outlet 11 to form a complete drainage system.

[0038] When cleaning the sludge inside the tower body 1, multiple guide plates 4 can be rotated so that each guide plate 4 is positioned opposite to an outlet 11. That is, one end of the guide plate 4 is rotated to fit against the inner wall of the tower body 1, and the upper surface of the guide plate 4 corresponds to the outlet 11. Moreover, multiple guide plates 4 can be combined to form a guide hood. When the packing layer 2 is flushed with a high-pressure water gun, the sewage containing sludge that flows down will be guided by the guide hood and smoothly discharged from the tower body 1 through the outlet 11 and the outlet pipe 6.

[0039] Wastewater is discharged directly through the outlet pipe 6, which not only effectively prevents sludge from flowing into the cold water pool 3, but also reduces the difficulty of cleaning and improves work efficiency. At the same time, since the outlet 11 and the outlet pipe 6 are arranged at intervals along the circumference, it ensures that the wastewater inside the tower body 1 can be discharged evenly, further improving the cleaning effect.

[0040] Please see Figure 2 and Figure 3 In some embodiments, a water-blocking component 7 may also be provided on the inner side wall of the tower body 1. The water-blocking component 7 is located between the water outlet 11 and the packing layer 2, and the water-blocking component 7 protrudes from the inner side wall of the tower body 1 toward the central axis of the tower body 1. The water-blocking component 7 is arranged in a ring along the circumference of the tower body 1 to form an annular protrusion structure.

[0041] When the high-pressure water gun is used to rinse the packing layer 2, the sewage flowing down the inner wall of the tower body 1 will be blocked by the water baffle 7. The water baffle 7 can guide the sewage to flow onto the guide shroud, so that the sewage will not flow down the inner wall of the tower body 1 from the gap between the guide shroud and the tower body 1 to the cold water pool 3. Therefore, the combination of the water baffle 7 and the guide shroud can form a complete sewage guiding system.

[0042] Please see Figure 2 and Figure 3 In some embodiments, the water-blocking component 7 is inclined toward the cold water pool 3 relative to the inner wall of the tower body 1, so that while blocking sewage, the water-blocking component 7 can more effectively guide the sewage to flow downward and prevent sewage from accumulating on the water-blocking component 7.

[0043] Specifically, when the high-pressure water gun is used to rinse the packing layer 2, the sewage flowing down the inner wall of the tower body 1 first comes into contact with the inclined water baffle 7. Due to the inclination angle of the water baffle 7, the sewage will flow downward along the surface of the water baffle 7, that is, towards the cold water pool 3. Since there is a flow guide hood below the water baffle 7, the sewage will be intercepted by the flow guide hood as it flows towards the cold water pool 3, and the sewage will be guided to the outlet pipe 6 to be discharged from the tower body 1. This ensures that the sewage will not flow directly into the cold water pool 3 and pollute the water quality, and makes full use of the synergistic effect of the water baffle 7 and the flow guide hood to form an efficient sewage guidance and discharge system.

[0044] Please see Figure 2 and Figure 3 In some embodiments, the cooling tower 100 may further include a water supply pipe 8, which is located inside the tower body 1. The portion of the water supply pipe 8 located inside the tower body 1 is arranged vertically. In particular, the central axis of the vertically arranged portion of the water supply pipe 8 is coaxial with the central axis of the tower body 1, so that the portion of the water supply pipe 8 is located in the middle of the tower body 1.

[0045] Specifically, multiple guide plates 4 can be arranged sequentially along the circumference of the water supply pipe 8, and one end of each guide plate 4 can be rotatably installed on the side wall of the water supply pipe 8, so that each guide plate 4 can rotate relative to the water supply pipe 8. Similarly, multiple support members 5 can also be arranged sequentially along the circumference of the water supply pipe 8, and one end of each support member 5 can also be rotatably installed on the side wall of the water supply pipe 8. When the multiple guide plates 4 rotate to form a guide hood, the other end of each support member 5 can rotate to support below a guide plate 4, so that the guide hood is firmly installed directly above the cold water pool 3.

[0046] Please see Figure 2 and Figure 3 In some embodiments, the cooling tower 100 may also include a spray structure 9 located above the packing layer 2.

[0047] Specifically, one end of the water supply pipe 8 can be connected to an external water source in the tower body 1, while the other end of the water supply pipe 8 can extend above the packing layer 2 and connect to the spray structure 9, allowing external water to flow to the spray structure 9 through the water supply pipe 8. Of course, to ensure sufficient water pressure, the water supply pipe 8 is also connected to a water pump. The spray structure 9 includes a horizontal water pipe and multiple high-pressure nozzles 91. The horizontal water pipe is connected to the water supply pipe 8, and the multiple high-pressure nozzles 91 are respectively connected to the horizontal water pipe. These high-pressure nozzles 91 can generate high-pressure water flow to flush the packing layer 2.

[0048] When it is necessary to clean the sludge on the packing layer 2, simply start the water pump, and external water will flow into the horizontal water pipe through the water inlet pipe 8 and be sprayed out by the high-pressure nozzle 91. These high-pressure water jets can powerfully impact the packing layer 2, washing away the attached sludge. The washed-off sludge and sewage are then collected by the guide shroud and the water outlet pipe 6 and discharged from the tower body 1, enabling the cooling tower 100 to be automatically cleaned.

[0049] Please see Figure 2 and Figure 4 In some embodiments, a reset member 10 may be provided at the rotatable mounting point of the support member 5.

[0050] Specifically, one end of the support member 5 is rotatably mounted on the water supply pipe 8 via a rotating shaft, and the reset member 10 can be set on the rotating shaft, or the reset member 10 can be connected to the support member 5 and the water supply pipe 8. After cleaning the packing layer 2, the guide member is rotated upward so that the guide member is disengaged from the support member 5. The reset member 10 can drive the support member 5 to rotate back to its original position, that is, the reset member 10 drives the support member 5 to rotate back to the vertical state so that the reset member 10 can reset the support member 5.

[0051] Please see Figure 4 In some embodiments, the reset member 10 may include a torsion spring 101, which may be sleeved on the pivot between the support member 5 and the tower body 1.

[0052] Specifically, one end of the support member 5 is rotatably mounted on the water supply pipe 8 inside the tower body 1 via a rotating shaft, and the torsion spring 101 is sleeved on the rotating shaft. The two opposite ends of the torsion spring 101 are respectively connected to the support member 5 and the water supply pipe 8. When cleaning the packing layer 2, the support member 5 needs to be rotated so that the support member 5 is supported below the guide member. At this time, the support member 5 and the water supply pipe 8 will pull the torsion spring 101. After cleaning the packing layer 2 and when the guide member is removed from the support member 5, the torsion spring 101 will drive the support member 5 back to its original position.

[0053] In some other embodiments, the reset member 10 may also include an elastic rope 102. One end of the elastic rope 102 may be connected to the support member 5, and the other end of the elastic rope 102 may be connected to the water inlet pipe 8. Similarly, when cleaning the filler layer 2, the support member 5 needs to be rotated so that the support member 5 is supported under the guide member. The support member 5 will stretch the elastic rope 102. After cleaning the filler layer 2, the elastic rope 102 will drive the support member 5 back to its original position. Of course, the reset member 10 may also include a torsion spring 101 and an elastic rope 102 at the same time.

[0054] Please see Figure 2 and Figure 4 In some embodiments, the guide plate 4 may have a slot 41 on the side facing the support member 5, and the end of the support member 5 supported on the guide plate 4 may be engaged in the slot 41, so that the support member 5 can more firmly support the guide plate 4, and the guide shield formed by multiple guide plates 4 can be more secure.

[0055] Please see Figure 2 and Figure 5 In some embodiments, the side of the guide plate 4 may be provided with a water-absorbing element 42, and the water-absorbing element 42 is located on one end face of the guide plate 4.

[0056] Specifically, when multiple guide plates 4 unfold and enclose to form a guide shroud, a water-absorbing component 42 can be squeezed between each guide plate 4 and the inner wall of the tower body 1. The water-absorbing component 42 here not only enhances the sealing between the guide plate 4 and the tower body 1, preventing sewage from leaking into the cold water pool 3 from the gap between the guide plate 4 and the tower body 1, but also effectively absorbs the sewage flowing down from the inner wall of the tower body 1, enhancing the sealing and stability of the guide shroud and bringing great convenience to cleaning the cooling tower 100.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
