Description

Technical Field

[0001] This application relates to the field of cooling tower technology, specifically to an automatic exhaust water distribution system for cooling towers and a cooling tower. Background Technology

[0002] The water distribution system is a crucial component of a counter-flow cooling tower, and its effectiveness directly impacts the tower's operational efficiency. In related technologies, the water distribution system includes an inlet pipe, a distribution pipe, and spray nozzles mounted on the distribution pipe. The distribution pipe is located at the top of the packing material and extends horizontally. The inlet pipe connects to the distribution pipe; water enters the distribution pipe after passing through the inlet pipe and is ultimately sprayed out by the spray nozzles. However, the liquid within the distribution pipe contains air bubbles, affecting the uniform distribution of water. Along the distribution pipe's extension path, the water pressure varies progressively, resulting in inconsistent water pressure at the spray nozzles along the pipe's length. This leads to varying water volumes from each nozzle, reducing the water distribution area and causing some areas on the packing surface to remain dry (dry zones), thus decreasing the cooling tower's efficiency. Utility Model Content

[0003] To address one of the aforementioned technical deficiencies, this application provides an automatic air venting water distribution system and a cooling tower, thereby solving the technical problem in the prior art where air bubbles exist in the pipes of the water distribution system, affecting the uniform distribution of water.

[0004] The technical solution adopted in this application is as follows: The primary objective of this application is to provide an automatic venting water distribution system for cooling towers, comprising: The final-stage water distribution pipe is located in a horizontal plane; An intermediate water distribution pipe, which is connected to the final water distribution pipe; An exhaust pipe is connected to the final-stage water distribution pipe. The diameter of the exhaust pipe is smaller than that of the final-stage water distribution pipe. The exhaust pipe is connected to the top of the final-stage water distribution pipe and is connected to the final-stage water distribution pipe. Liquid is discharged after passing through the intermediate-stage water distribution pipe and the final-stage water distribution pipe in sequence.

Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] Example 1 like Figures 1 to 6 As shown, Embodiment 1 of this disclosure provides an automatic venting water distribution system for a cooling tower. The water distribution system includes: a final-stage water distribution pipe 3 and an intermediate-stage water distribution pipe 2. The final-stage water distribution pipe 3 is located in a horizontal plane. The intermediate-stage water distribution pipe 2 is connected to the final-stage water distribution pipe 3. An exhaust pipe 10 is connected to the final-stage water distribution pipe 3. The diameter of the exhaust pipe 10 is smaller than that of the final-stage water distribution pipe 3. The exhaust pipe 10 is connected to the top end of the final-stage water distribution pipe 3 and is connected to the final-stage water distribution pipe 3. Liquid is discharged after passing through the intermediate-stage water distribution pipe 2 and the final-stage water distribution pipe 3 in sequence.

[0022] The water distribution system of this application is equipped with an exhaust pipe 10 on the final-stage water distribution pipe 3, which can effectively expel air bubbles from the water distribution system. Expelling air bubbles entering the final-stage water distribution pipe 3 prevents obstruction of water flow and avoids uneven water distribution. The function of the exhaust pipe 10 is to allow compressed air to escape, thus maintaining the normal operation of the water distribution system. Simultaneously, the exhaust pipe 10 is connected to the outside air, forming a U-shaped pipe structure with the intermediate-stage water distribution pipe 2, the final-stage water distribution pipe 3, and the exhaust pipe 10. This ensures uniform water flow rate and pressure within the water distribution system, consistent water pressure to each branch pipe 8 and nozzle 9, and equal water volume sprayed from each nozzle 9, achieving a uniform water distribution effect.

[0023] In some possible embodiments, the exhaust pipe 10 is located at the end of the final-stage water distribution pipe 3 along its length. This facilitates the discharge of air bubbles throughout the final-stage water distribution pipe 3. When the final-stage water distribution pipe 3 is unevenly arranged, one end may be higher than the other. In this application, the exhaust pipe 10 is located at the end of the final-stage water distribution pipe 3, at the highest point. Air bubbles within the final-stage water distribution pipe 3 will naturally move to the end of the final-stage water distribution pipe 3 and eventually be discharged through the exhaust pipe 10.

[0024] In some possible implementations, such as Figure 1 As shown, the final-stage water distribution pipe 3 is equipped with exhaust pipes 10 at at least both ends. By providing exhaust pipes 10 at both ends of the final-stage water distribution pipe 3, it is more conducive to the discharge of air bubbles. The exhaust pipes 10 at both ends of the final-stage water distribution pipe 3 allow compressed air on both sides to be discharged through the exhaust pipes 10, thereby maintaining the normal operation of the water distribution system. Furthermore, regardless of the direction in which the final-stage water distribution pipe 3 is tilted, air bubbles will be discharged through the corresponding exhaust pipe 10.

[0025] In some possible implementations, the intermediate water distribution pipe 2 is located on top of the final water distribution pipe 3, and the intermediate water distribution pipe 2 is parallel to the exhaust pipe 10.

[0026] The intermediate water distribution pipe 2 has an open top. The intermediate water distribution pipe 2, the final water distribution pipe 3 and the exhaust pipe 10 form a U-shaped pipe structure, which ensures that the water flow rate and water pressure in the water distribution system are uniform, the water pressure to each branch pipe 8 and the spray nozzle 9 are also consistent, and the amount of water sprayed by each spray nozzle 9 is equal, so as to achieve the effect of uniform water distribution.

[0027] In some possible implementations, the extension length of the exhaust pipe 10 and the extension length of the intermediate water distribution pipe 2 are equal in the direction perpendicular to the horizontal plane.

[0028] The intermediate water distribution pipe 2, the final water distribution pipe 3, and the vent pipe 10 form a U-shaped pipe structure. The water levels in the intermediate water distribution pipe 2 and the vent pipe 10 are the same. Therefore, the two should be kept as close to the same height as possible to avoid water overflowing from the vent pipe 10 when the vent pipe 10 is too low and the water level is too high.

[0029] In some possible implementations, the diameter of the vent pipe 10 is smaller than the diameter of the intermediate water distribution pipe 2. The diameter of the vent pipe 10 has little impact on the venting; therefore, in this embodiment, minimizing the diameter of the vent pipe 10 helps to reduce the weight of the entire water distribution system.

[0030] In some possible implementations, the final stage water distribution pipe 3 is closed at both ends along its length. Vent pipes 10 are installed at both ends of the final stage water distribution pipe 3, thus the closed ends facilitate stable water pressure throughout the entire final stage water distribution pipe 3, ensuring uniform water flow rate and pressure, consistent water pressure directed to each branch pipe 8 and nozzle 9, and equal water volume sprayed from each nozzle 9, achieving a uniform water distribution effect.

[0031] In some possible implementations, the self-balancing uniform water distribution system includes multiple branch pipes 8, each of which is located within the final-stage water distribution pipe 3. The branch pipes 8 are spaced apart sequentially along the length of the final-stage water distribution pipe 3, and each branch pipe 8 is connected to a spray nozzle 9. The branch pipes 8 can be arranged symmetrically along the length of the final-stage water distribution pipe 3, ensuring consistent water pressure between the symmetrically arranged branch pipes 8 and spray nozzles 9, and resulting in approximately equal water volume sprayed from each spray nozzle 9, thus achieving uniform water distribution.

[0032] In some possible implementations, each final-stage water distribution pipe 3 is connected to at least two intermediate-stage water distribution pipes 2. Each intermediate-stage water distribution pipe 2 is symmetrically arranged on the final-stage water distribution pipe 3 with the middle part (the middle part in the length direction) as the center. The symmetrical arrangement of the intermediate-stage water distribution pipes 2 on the final-stage water distribution pipe 3 ensures that the water supply paths of each branch pipe on the final-stage water distribution pipe 3 are approximately the same, the water supply paths of each branch pipe are basically consistent, and the water volume sprayed by each nozzle 9 on each branch pipe 8 is approximately equal, achieving the effect of uniform water distribution.

[0033] Example 2 like Figures 1 to 6 As shown in the embodiment of this application, the water distribution system is further described in detail, including: a primary water distribution pipe 1, an intermediate water distribution pipe 2, and a final water distribution pipe 3. The primary water distribution pipe 1 extends longitudinally, has an inlet at its bottom, and a pressure relief port 11 at its top. Each intermediate water distribution pipe 2 is located around the primary water distribution pipe 1 and is connected to the primary water distribution pipe 1. Each intermediate water distribution pipe 2 has a top opening 21. Each final water distribution pipe 3 is located at the bottom of the corresponding intermediate water distribution pipe 2 and is connected to the corresponding intermediate water distribution pipe 2. Liquid flows sequentially through the primary water distribution pipe 1, the intermediate water distribution pipe 2, and the final water distribution pipe 3 and is finally discharged.

[0034] The primary water distribution pipe 1 of this application is provided with a pressure relief port 11 at the top, so that the water will automatically depressurize after entering the primary water distribution pipe 1 and flow evenly into multiple intermediate water distribution pipes 2 around it under its own weight for double uniform water distribution. The water level in each intermediate water distribution pipe 2 is the same. The water will flow to the final water distribution pipe 3 again. The pressure at each spray nozzle 9 directly or indirectly connected to the final water distribution pipe 3 is approximately the same. The water output and spray area of ​​each spray nozzle 9 are approximately the same, thereby achieving uniform water distribution, which is not affected by the inlet water pressure and significantly improves the cooling efficiency of the cooling tower.

[0035] It should be noted that, in this embodiment, the self-balancing uniform water distribution system is not limited to only three-stage water distribution pipes; more stages of water distribution pipes can be arranged according to actual conditions. For example, a fourth-stage water distribution pipe, a fifth-stage water distribution pipe, and so on can be arranged downstream of the final-stage water distribution pipe 3.

[0036] In some possible implementations, the self-balancing uniform water distribution system includes a plurality of connecting pipes 4, the diameter of which is smaller than that of the intermediate water distribution pipe 2 and the primary water distribution pipe 1. Each of the connecting pipes 4 is arranged sequentially at intervals along the circumference of the primary water distribution pipe 1, and each of the connecting pipes 4 is located in the same plane. One end of each of the connecting pipes 4 is connected to the primary water distribution pipe 1, and the other end of each of the connecting pipes 4 is connected to the corresponding intermediate water distribution pipe 2.

[0037] The outer diameter of the connecting pipe 4 is much smaller than that of the primary water distribution pipe 1, facilitating the connection of multiple connecting pipes 4 to the same height section of the primary water distribution pipe 1. The primary water distribution pipe 1 has multiple openings spaced apart circumferentially, all at the same height. Multiple connecting pipes 4 are sequentially spaced around the circumference of the primary water distribution pipe 1 and connected to their respective openings. All connecting pipes 4 are located in the same horizontal plane. Each intermediate water distribution pipe 2 is arranged parallel to the primary water distribution pipe 1. The outer diameter of the intermediate water distribution pipe 2 is no larger than that of the primary water distribution pipe 1. The number of intermediate water distribution pipes 2 can be two, three, four, or more.

[0038] The connecting pipe 4 can be vertically connected to the primary water distribution pipe 1 and the intermediate water distribution pipe 2 respectively. Each connecting pipe 4 can be formed by splicing together several cylindrical pipes. Adjacent cylindrical pipes can be connected and fixed by clamps.

[0039] In some possible implementations, such as Figure 1 As shown, at least two adjacent intermediate water distribution pipes 2 are connected by a connecting pipe 5 along the circumferential direction of the primary water distribution pipe 1. The connecting pipe 5 connects the two intermediate water distribution pipes 2 at both ends, and the connecting pipe 5 is located between the connecting pipe 4 and the final water distribution pipe 3 in the height direction.

[0040] The connection pipe 5 increases the overall structural strength of each intermediate water distribution pipe 2, resulting in a well-integrated water distribution system that is less prone to deformation and extends its service life. The connection pipe 5 can be a hollow pipe, connecting two adjacent intermediate water distribution pipes 2 to form a U-shaped pipe structure between each pair. This ensures uniform water flow rate and pressure within the water distribution system, consistent water pressure supplied to each final-stage water distribution pipe 3, and equal water volume distributed to each final-stage water distribution pipe 3, achieving a uniform water distribution effect.

[0041] In some possible implementation schemes, combined Figure 1 and Figure 2 As shown, the self-balancing uniform water distribution system includes a pressure relief and water blocking component 6, which is disposed on the primary water distribution pipe 1 and covers the cross-section of the primary water distribution pipe 1. The pressure relief and water blocking component 6 has a vent hole 61.

[0042] The primary water distribution pipe 1 of this application is provided with a pressure relief port 11 at the top, so that the water will automatically depressurize after entering the primary water distribution pipe 1, and under its own weight, it will flow evenly into the multiple intermediate water distribution pipes 2 on the periphery for double uniform water distribution. The primary water distribution pipe 1 is provided with a pressure relief and water blocking component 6, which does not affect the water inlet pressure relief, and at the same time serves to block water and prevent the inlet water from being discharged directly from the pressure relief port 11 of the primary water distribution pipe 1.

[0043] In some possible implementations, the self-balancing uniform water distribution system includes a main inlet pipe 7, the outer diameter of which is smaller than the outer diameter of the primary water distribution pipe 1. The main inlet pipe 7 is located at the bottom of the primary water distribution pipe 1 and is connected to the inlet at the bottom of the primary water distribution pipe 1.

[0044] A water pump can be installed at the bottom of the main inlet pipe 7 to pump water from bottom to top into the primary water distribution pipe 1. The primary water distribution pipe 1 is used to depressurize the incoming water and needs to distribute it to the various intermediate water distribution pipes 2. Therefore, the primary water distribution pipe 1 is a water storage tank with a large diameter to meet the requirements of water storage and distribution.

[0045] In some possible implementations, each of the final-stage water distribution pipes 3 is located in the same plane, and each of the final-stage water distribution pipes 3 has the same size and shape. Each final-stage water distribution pipe 3 is connected to the same number of intermediate-stage water distribution pipes 2, and each intermediate-stage water distribution pipe 2 is symmetrically arranged on the final-stage water distribution pipe.

[0046] In this implementation scheme, the size and shape of each final-stage water distribution pipe 3 are the same or symmetrical, so that the water supply path of each final-stage water distribution pipe 3 is roughly the same along the path from the primary water distribution pipe 1, the intermediate water distribution pipe 2 to the final-stage water distribution pipe 3. Therefore, the water pressure in each final-stage water distribution pipe 3 is basically the same, and each final-stage water distribution pipe 3 can drain water evenly, thereby achieving uniform water distribution, unaffected by the inlet water pressure, and significantly improving the cooling efficiency of the cooling tower.

[0047] In some possible implementation schemes, combined Figure 1 and Figure 4 As shown, the self-balancing uniform water distribution system includes multiple water distribution pipes 8, each of which is located within the final-stage water distribution pipe 3. The water distribution pipes 8 are arranged at intervals along the length of the final-stage water distribution pipe 3. Each water distribution pipe 8 is connected to a spray nozzle 9. The water distribution pipes 8 are symmetrically arranged within the final-stage water distribution pipe 3, with the center point (midpoint along the length direction) as the center. The water distribution pipes 8 can be arranged in this manner along the length of the final-stage water distribution pipe 3. The number and position of the spray nozzles 9 on each water distribution pipe 8 are equal, ensuring that the water pressure of the symmetrically arranged water distribution pipes 8 and spray nozzles 9 is approximately the same, and the water volume sprayed by each spray nozzle 9 is approximately equal, achieving a uniform water distribution effect.

[0048] In some possible implementation schemes, combined Figure 1 and Figure 3 As shown, the self-balancing uniform water distribution system includes an exhaust pipe 10, which is connected to the end of the final stage water distribution pipe 3.

[0049] The water distribution system of this application has an exhaust pipe 10 installed on the final water distribution pipe 3, which can effectively remove air bubbles in the water distribution system. At the same time, the exhaust pipe 10 is connected to the outside air, so that the intermediate water distribution pipe 2, the final water distribution pipe 3 and the exhaust pipe 10 form a U-shaped pipe structure, which ensures that the water flow rate and water pressure in the water distribution system are uniform, the water pressure to each branch pipe 8 and the spray nozzle 9 are also consistent, and the water volume sprayed by each spray nozzle 9 is equal, so as to achieve the effect of uniform water distribution.

[0050] In some possible implementation schemes, combined Figure 5 and Figure 6 As shown, the self-balancing uniform water distribution system includes multiple water distribution sub-units 100, which are arranged in multiple rows and columns on a horizontal plane. Each water distribution sub-unit 100 includes a primary water distribution pipe 1, an intermediate water distribution pipe 2, and a final water distribution pipe 3. The structure of each water distribution sub-unit 100 is as described above. An appropriate number of water distribution sub-units 100 can be selected according to the actual size and needs of the cooling tower. Each water distribution sub-unit 100 may have a corresponding main water inlet pipe 7, and each main water inlet pipe 7 may be connected to a water pump. Alternatively, each main water inlet pipe 7 may be connected to a main pipe, and a water pump may be installed on the main pipe.

[0051] Example 3 like Figure 1 and Figure 2 As shown, this application embodiment, based on the above-described Embodiments 1 and 2, further details the water distribution system. The water distribution system includes: a primary water distribution pipe 1, a pressure relief and water-blocking component 6, and an intermediate water distribution pipe 2. The primary water distribution pipe 1 extends longitudinally, has a water inlet at its bottom, and a pressure relief port 11 at its top. The pressure relief and water-blocking component 6 is disposed on the primary water distribution pipe 1 and covers its cross-section. The pressure relief and water-blocking component 6 has a vent hole 61. The intermediate water distribution pipe 2 is located around the primary water distribution pipe 1 and connected to its outer wall. The intermediate water distribution pipe 2 and the primary water distribution pipe 1 are connected.

[0052] The primary water distribution pipe 1 of this application is provided with a pressure relief port 11 at the top, so that the water will automatically depressurize after entering the primary water distribution pipe 1 and flow evenly into the multiple intermediate water distribution pipes 2 around it under its own weight for double uniform water distribution. The primary water distribution pipe 1 is provided with a pressure relief and water blocking component 6, which has a vent hole 61. It does not affect the water inlet pressure relief, and the compressed gas can be easily discharged. The pressure relief and water blocking component 6 also serves to block water, preventing the inlet water from being discharged directly from the pressure relief port 11 at the top of the primary water distribution pipe 1.

[0053] In some possible embodiments, such as Figure 1 and Figure 2 As shown, the pressure relief and water-blocking component 6 is disposed within the cavity of the primary water distribution pipe 1. This does not occupy additional external space in the water distribution system, which is beneficial for the compact design of the system. Furthermore, by placing the pressure relief and water-blocking component 6 within the cavity of the primary water distribution pipe 1, and maintaining a certain gap from the pressure relief port 11, water can be blocked in advance, more effectively preventing water from being discharged from the top pressure relief port 11. Without considering space occupation, the pressure relief and water-blocking component 6 can also be at least partially exposed at the top of the primary water distribution pipe 1, covering the pressure relief port 11.

[0054] In some possible implementations, the pressure relief and water-blocking component 6 is detachably connected to the primary water distribution pipe 1. This allows for easy replacement of the pressure relief and water-blocking component 6. The pressure relief and water-blocking component 6 can be detachably connected to the primary water distribution pipe 1 via fasteners, or it can be detachably connected to the primary water distribution pipe 1 via a snap-fit ​​structure.

[0055] In some possible implementations, the pressure relief and water-blocking component 6 is fixedly connected to the primary water distribution pipe 1. The pressure relief and water-blocking component 6 can be fastened to the primary water distribution pipe 1 with fasteners. The pressure relief and water-blocking component 6 can be fixed to the primary water distribution pipe 1 by welding or bonding.

[0056] In some possible implementations, the primary water distribution pipe 1 is a circular pipe, and the pressure relief and water-blocking component 6 is a disc-shaped component. The pressure relief and water-blocking component 6 is located on the inner wall of the primary water distribution pipe 1, and the thick end face of the peripheral side of the pressure relief and water-blocking component 6 is attached to the inner wall of the primary water distribution pipe 1. A large number of vent holes 61 are distributed on the pressure relief and water-blocking component 6, and the vent holes 61 penetrate the pressure relief and water-blocking component 6 along the thickness direction of the pressure relief and water-blocking component 6.

[0057] In some possible implementations, the open water distribution system for the cooling tower includes at least two of the aforementioned pressure relief and water-blocking components 6, each of which is arranged sequentially along the length of the primary water distribution pipe 1. The pressure relief and water-blocking components 6 can be spaced apart. By providing multiple pressure relief and water-blocking components 6, the water-blocking effect is further enhanced. After the high-speed water flow enters from the inlet at the bottom of the primary water distribution pipe 1 and reaches a certain height, it is blocked by multiple pressure relief and water-blocking components 6, thus reducing the inlet flow velocity and achieving rapid pressure relief. When the inlet water passes through one pressure relief and water-blocking component 6, it will also be blocked by the previous stage pressure relief and water-blocking component 6. Through the water-blocking effect of multiple stages of pressure relief and water-blocking components 6, a rapid pressure relief effect can be achieved.

[0058] In some possible implementations, the open water distribution system for the cooling tower has at least partially offset vent holes 61 on two adjacent pressure relief and water-blocking components 6 along the length of the primary water distribution pipe 1. This offset arrangement of the vent holes 61 on adjacent pressure relief and water-blocking components 6 can prevent some water from smoothly passing through the vent holes 61 on the two pressure relief and water-blocking components 6 sequentially along the longitudinal direction, thus avoiding poor pressure relief effect of the pressure relief and water-blocking components 6.

[0059] In some possible implementations, the pressure relief and water-blocking component 6 is welded to the inner wall of the primary water distribution pipe 1 along its periphery.

[0060] The inner wall of the primary water distribution pipe 1 may be provided with a positioning support, on which the pressure relief and water-blocking component 6 is supported. The support serves as a limiting support, assisting in the rapid assembly of the pressure relief and water-blocking component 6. For example, during the assembly of the pressure relief and water-blocking component 6, the pressure relief and water-blocking component 6 is first placed inside the primary water distribution pipe 1 and horizontally supported on the positioning support, and then welding or fastener assembly is performed to fix the pressure relief and water-blocking component 6 to the primary water distribution pipe 1. It should be noted that the positioning support may be an internal rib formed by protrusions from the inner wall of the primary water distribution pipe 1.

[0061] In some possible implementations, the intermediate water distribution pipe 2 is connected to the primary water distribution pipe 1 via a connecting pipe 4, and the pressure relief and water blocking component 6 is located in the height direction between the connecting pipe 4 and the pressure relief port 11.

[0062] The pressure relief and water-blocking component 6 is positioned higher than each connecting pipe 4, which reduces the impact on the diversion of water in the primary water distribution pipe 1 to the intermediate water distribution pipe 2. This is beneficial for the uniform distribution of water in the water distribution system.

[0063] Example 4 Embodiment 4 of this application provides a cooling tower, including the water distribution system described in the above embodiment. Specifically, the water-cooled tower may include a tower body, packing material, and the aforementioned water distribution system. The packing material is disposed on the tower body, and the water distribution system is disposed on the tower body and located at the top of the packing material. The water distribution system sprays water onto the packing material, increasing the contact area and time between the water and air, thereby reducing the water temperature through heat exchange between the water and air.
