Description

Technical Field

[0001] This disclosure relates to the field of refrigeration technology, and in particular to a water distribution system, a cooling tower, and an integrated cooling station. Background Technology

[0002] As a core heat dissipation device in industrial circulating water systems, the uniformity of water distribution in crossflow cooling towers directly affects the heat exchange efficiency of the packing material and the operational stability of the equipment. With the trend towards integrated systems, cooling towers often employ side-inlet water intake to reduce piping.

[0003] The elongated water distribution plate in the related technology will face the problem of hydraulic imbalance when the water is close to the side: under high flow conditions, the inertia of the water flow will cause the water layer to form in the far end of the water distribution plate due to the untimely water discharge, resulting in large fluctuations in liquid level and easy overflow; under low flow conditions, the water flow power is insufficient to reach the far end of the water distribution plate, causing local drying and easy to cause scaling of the packing. Utility Model Content

[0004] In view of this, the present disclosure provides a water distribution system, a cooling tower, and an integrated cooling station, which can improve the uniformity of water distribution.

[0005] In one aspect of this disclosure, a water distribution system is provided, comprising:

[0006] A water distribution device has a disc body and a flow guide. The flow guide is disposed on the bottom surface of the disc body and extends along a first direction. The flow guide is configured to divide the disc body into a water distribution area and an adjustment area along a second direction. Multiple spray holes are opened on the bottom surface of the water distribution area. The flow guide and the disc body are spaced apart at both ends along the first direction.

[0007] A water supply device, disposed at one end of the plate along a first direction, is configured to provide a water flow toward the water distribution area; and

[0008] An energy-consuming device is installed at one end of the plate near the water supply device and connected to the water supply device. It has a first energy-consuming part installed in the water flow path and a second energy-consuming part installed at an angle to the first energy-consuming part. The first energy-consuming part has a first water outlet hole facing the water distribution area and the second energy-consuming part has a second water outlet hole facing the adjustment area.

[0009] The first direction is parallel to the length direction of the disk body, and the second direction is parallel to the width direction of the disk body.

[0010] In some embodiments, the water outlet area of ​​the first water outlet is larger than that of the second water outlet.

[0011] In some embodiments, the first water outlet is an elongated groove extending along a second direction, and the second water outlet is a circular hole.

[0012] In some embodiments, the number of first water outlet holes is multiple.

[0013] In some embodiments, a plurality of first water outlet holes are arranged at equal intervals along the vertical direction.

[0014] In some embodiments, the number of second water outlets is multiple.

[0015] In some embodiments, a plurality of second water outlets are arranged at equal intervals along the vertical direction and / or the first direction.

[0016] In some embodiments, the water supply device includes a water supply pipe disposed on a first end face of the pan body, the water supply pipe extending along a first direction.

[0017] In some embodiments, the inlet of the water supply pipe is higher than the first outlet and / or the second outlet.

[0018] In some embodiments, the bottom of the first energy-consuming part is connected to the first end face of the disk body and is inclined relative to the end face of the disk body.

[0019] In some embodiments, the angle between the first energy-consuming part and the first end face of the disk body is in the range of 45° to 75°.

[0020] In some embodiments, the number of guide members is two, which are spaced apart along the second direction to divide the disc into a water distribution area and two adjustment areas;

[0021] There are two second energy-consuming parts, which are arranged at intervals on both sides of the first energy-consuming part along the second direction.

[0022] In some embodiments, the energy-consuming device further includes:

[0023] The sealing plate is connected to the top of the first energy-consuming part and the two second energy-consuming parts respectively, so as to form an energy-consuming cavity with the first energy-consuming part, the two second energy-consuming parts and the first end face of the disk body.

[0024] In some embodiments, the height of the guide is higher than the rated water level of the disc.

[0025] In some embodiments, the second energy-consuming part is arranged parallel to the first direction and abuts against the end of the flow guide.

[0026] In another aspect of this disclosure, a cooling tower is provided, comprising:

[0027] Such as any of the water distribution systems mentioned above.

[0028] In another aspect of this disclosure, an integrated cooling station is provided, comprising:

[0030] Therefore, according to the embodiments of this disclosure, by dividing the disc into a water distribution zone and a regulating zone, and by having the energy-consuming device provide water flows with different kinetic energies to the water distribution zone and the regulating zone respectively, the matching of the water supply flow rate and the water distribution flow state can be achieved. This enables self-balancing regulation of overflow and shortage under different water supply flow conditions, reducing the risk of imbalance due to high flow overflow and low flow spray hole shortage under large-span water distribution conditions, and helping to achieve more uniform water distribution and better spraying effect.

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0049] As a core heat dissipation device in industrial circulating water systems, the uniformity of water distribution in crossflow cooling towers directly affects the heat exchange efficiency of the packing material and the operational stability of the equipment. With the trend towards integrated systems, cooling towers often employ side-inlet water intake to reduce piping.

[0050] To meet the requirement of integrated assembly of the cooling tower and the refrigeration station, the tower width is reduced, the tower length is increased, and the water distribution tray is elongated and has a large span. The elongated water distribution tray in related technologies faces hydraulic imbalance problems when water is introduced from the side: under high flow conditions, the inertia of the water flow causes water to accumulate in the far end of the tray due to delayed water output, resulting in large liquid level fluctuations and easy overflow; under low flow conditions, insufficient water flow power makes it difficult to reach the far end of the tray, causing localized drying and easily leading to scaling of the packing material. Uneven water distribution will affect the spraying effect and heat exchange performance.

[0051] Some related technologies use a combination of graded narrow-diameter long pipes and orifice water distribution, but these have drawbacks such as complex structure, slow adjustment, and inability to adapt to wide-range flow changes.

[0052] In view of this, in one aspect of the present disclosure, a water distribution system is provided that can improve the uniformity of water distribution.

[0053] Figure 1 These are schematic diagrams of the structure of some embodiments of the water distribution system according to this disclosure. Figure 2 These are partial schematic diagrams of some embodiments of the water distribution system according to this disclosure. Figure 2 The arrows in the diagram indicate the direction of water flow. Figure 3 This is a partial schematic diagram of some other embodiments of the water distribution system according to the present disclosure.

[0054] Figure 1 In the diagram, direction A is the first direction, direction B is the second direction, and direction C is the third direction. (Refer to...) Figures 1-3 The water distribution system includes a water distribution device, a water supply device 3, and an energy consumption device 4.

[0055] The water distribution device has a disc body 1 and a guide member 2. The guide member 2 is disposed on the bottom surface of the disc body 1 and extends along a first direction. The guide member 2 is configured to divide the disc body 1 into a water distribution area 11 and an adjustment area 12 along a second direction. A plurality of spray holes 110 are opened on the bottom surface of the water distribution area 11. The guide member 2 and the disc body 1 are spaced apart at both ends along the first direction.

[0056] A water supply device 3 is disposed at one end of the disc body 1 along a first direction and is configured to provide a flow of water toward the water distribution area 11. The water supply device 3 provides a coolant for spraying to the water distribution device. The coolant may include, but is not limited to, water and may be adjusted according to the actual application.

[0057] The energy-consuming device 4 is located at one end of the plate 1 near the water supply device 3 and is connected to the water supply device 3. It has a first energy-consuming part 41 located in the water flow path and a second energy-consuming part 42 located at an angle to the first energy-consuming part 41.

[0058] The first energy-consuming part 41 has a first water outlet 43 that flows towards the water distribution area 11, and the second energy-consuming part 42 has a second water outlet 44 that flows towards the regulating area 12. The first energy-consuming part 41 is configured to partially block the water flow from the water supply device 3 to consume energy from the water supplied by the water supply device 3. The second energy-consuming part 42 is configured to partially block the water flow blocked by the first energy-consuming part 41 so that the water that collides with the first energy-consuming part 41 consumes energy again.

[0059] The first direction is parallel to the length of the disc body 1, the second direction is parallel to the width of the disc body, and the third direction is parallel to the height of the disc body 1. The dimensions of the disc body 1 match the dimensions of the packing area below the water distribution device. The length-to-width ratio of the disc body is, but is not limited to, greater than 4, to better meet the requirements of integrated cooling station layout and water distribution. The packing includes, but is not limited to, air-water heat exchange components installed below the disc body 1 within the cooling tower.

[0060] The flow guide 2 is disposed within the disc body 1 along the length of the disc body 1, thereby dividing the disc body 1 into a water distribution area 11 and an adjustment area 12 along the width of the disc body 1. The flow guide 2 includes, but is not limited to, being flat and disposed perpendicular to the bottom surface of the disc body 1.

[0061] The guide 2 is spaced apart from both ends of the disc body 1. The water distribution area 11 and the regulating area 12 are connected through the space between the two ends, so that the water in the water distribution area 11 can flow to the regulating area 12 through the space, and the water in the regulating area 12 can flow to the water distribution area 11 through the space.

[0062] Spray holes 110 are only provided in the water distribution area 11. Spray holes 110 include, but are not limited to, round holes. Multiple spray holes 110 are equidistantly arranged in the water distribution area 11. Water flows from the spray holes 110 into the packing heat dissipation section below the water distribution device by gravity.

[0063] The widths of the water distribution zone 11 and the regulating zone 12 can be determined according to the size of the packing area, the size requirements of the integrated cooling station, etc. The width of the water distribution zone 11 includes, but is not limited to, matching the width of the heat dissipation section of the packing area, and the width of the regulating zone 12 includes, but is not limited to, matching the width of the water collection section and / or the air intake section of the packing area.

[0064] The energy-consuming device 4 is disposed inside the plate body 1, and is connected to the water supply device 3 through an opening at the end of the plate body 1. The energy-consuming device 4 is not limited to a partially enclosed box body, and the first energy-consuming part 41 and the second energy-consuming part 42 are not limited to being flat or arc-shaped.

[0065] The first energy-consuming part 41 is located in the water flow path. By colliding with the water flow, it consumes energy from the water entering the water distribution area 11, reducing the impact force of the water flow. After the water flow is dispersed by the collision with the first energy-consuming part 41, it collides a second time with the second energy-consuming part 42 located to the side of the first energy-consuming part 41, further decelerating and consuming energy. The shape and size of the first water outlet 43 and the second water outlet 44 can be selected according to factors such as water output requirements and the size of the water distribution device.

[0066] The distance between the flow guide 2 and the disk body 1 on the side closer to the energy-consuming device 4 is the first distance 51, and the distance between the flow guide 2 and the disk body 1 on the side farther from the energy-consuming device 4 is the second distance 52. The end of the disk body 1 closer to the energy-consuming device 4 is the proximal end, and the end of the disk body 1 farther from the energy-consuming device 4 is the distal end.

[0067] Figure 4A This is a schematic diagram of water distribution according to some embodiments of the water distribution system disclosed herein. Figure 4B These are schematic diagrams of water distribution systems according to other embodiments of the water distribution system disclosed herein. Figure 4A The diagram shown is a schematic of the water flow in the water distribution system when the water supply flow rate is large. Figure 4B The diagram shows the water flow of the water distribution system when the water supply flow rate is relatively low. When the water supply flow rate is relatively high, the water level in the basin 1 is 50%-120% of the rated water level; when the water supply flow rate is relatively low, the water level in the basin 1 is 10%-50% of the rated water level. The arrows in the diagram indicate the direction of water flow.

[0068] When the water supply flow rate of the water supply device 3 is small, since the spray hole 110 is not opened in the regulating zone 12, the water in the regulating zone 12 will not be dispersed. The water flowing from the second water outlet 44 to the regulating zone 12 will flow to the far end of the disc 1 and flow to the water distribution zone 11 through the second interval 52, so as to increase the water distribution at the far end of the disc 1 and reduce the situation where the spray hole 110 at the far end cannot obtain water supply and the packing dries up.

[0069] When the water supply flow rate of the water supply device 3 is large, the kinetic energy of the water flowing to the regulating zone 12 is less than that of the water flowing to the distribution zone 11 after the second energy consumption. The excess water at the far end of the distribution zone 11 overcomes the resistance of the water flow in the regulating zone 12 and flows back to the regulating zone 12 through the second interval 52.

[0070] The water flowing back to the regulating zone 12 then flows to the water distribution zone 11 through the first interval 51, where it accumulates in the area near the energy-consuming device 4 and is discharged through the spray hole 110. This balances the liquid level difference between the near end and the far end in the water distribution zone 11, reducing the occurrence of low water volume and low liquid level at the near end due to the high water flow velocity of the water supply device 3 and the inertial influence of the strong water flow thrust.

[0071] In this embodiment, by dividing the disc 1 into a water distribution zone 11 and an adjustment zone 12, and by having the energy-consuming device 4 provide water flows with different kinetic energies to the water distribution zone 11 and the adjustment zone 12 respectively, the matching of the water supply flow rate and the water distribution flow state is achieved. This enables self-balancing adjustment of overflow, overflow and shortage under different water supply flow conditions, reducing the risk of imbalance due to high flow overflow and low flow spray hole shortage under large-span water distribution conditions, and helping to achieve more uniform water distribution and better spraying effect.

[0072] refer to Figure 2 and Figure 3 In some embodiments, the water outlet area of ​​the first water outlet 43 is larger than that of the second water outlet 44.

[0073] In this embodiment, by setting the water outlet area of ​​the first water outlet 43 to be larger than that of the second water outlet 44, the second water outlet 44 can generate greater energy consumption for the water flow compared to the first water outlet 43. This results in a lower and more dispersed water flow velocity from the second water outlet 44, improving the reliability of the water flow from the far end of the water distribution zone 11 to flow back to the regulating zone 12 under high flow conditions, and further enhancing the regulating capacity of the regulating zone 12.

[0074] The low water flow rate of the second water outlet 44 can reduce splashing caused by contact with the inner wall of the disc 1, making the water flow in the regulating zone 12 more stable.

[0075] refer to Figure 2 and Figure 3 In some embodiments, the first water outlet 43 is a long groove extending along the second direction, and the second water outlet 44 is a round hole.

[0076] The width direction of the first energy-consuming part 41 and the first water outlet 43 is parallel to the width direction of the disc body 1. The width of the first energy-consuming part 41 can be determined according to the width of the disc body 1 and the water distribution area 11. The width of the first water outlet 43 is smaller than the width of the first energy-consuming part 41. The width of the first water outlet 43 is, but is not limited to, 20-30 mm, and can be adjusted according to the actual application.

[0077] The aspect ratio of the first water outlet 43 can be selected as 18:1 to 28:1, which can reduce the risk of excessive energy consumption and reduced water output kinetic energy caused by the width of the first water outlet 43 being too small, and the risk of excessive energy consumption, excessive water output kinetic energy, and violent liquid surface fluctuations caused by the width being too large.

[0078] The diameter of the second water outlet 44 is, but is not limited to, 15 to 20 mm. This can reduce the risk of excessive energy consumption and insufficient water output from the regulating zone 12 due to an excessively small diameter of the second water outlet 44, as well as the risk of insufficient energy consumption and water splashing due to an excessively large diameter.

[0079] In this embodiment, the first water outlet 43 is designed as a long groove, which helps to retain the kinetic energy of the water flow in the inlet direction, thereby increasing the water distribution span within the water distribution area 11. The second water outlet 44 is designed as a round hole, which can further enhance the energy dissipation intensity and water flow dispersion ability of the water flow, resulting in a lower water flow velocity from the second water outlet 44.

[0080] refer to Figure 2 and Figure 3 In some embodiments, there are multiple first water outlet holes 43. The number of first water outlet holes 43 includes, but is not limited to, 3 to 5, and the flow velocity of the first water outlet holes 43 is in the range of 1 to 1.5 m / s. The spacing between adjacent first water outlet holes 43 and the number of first water outlet holes 43 can be adjusted according to actual conditions.

[0081] In this embodiment, the number of first water outlet holes 43 is set to multiple, which can increase the water flow provided by the first energy-consuming part 41 to the water distribution area 11 per unit time, and help improve the water distribution efficiency of the water distribution system.

[0082] refer to Figure 2 and Figure 3 In some embodiments, multiple first water outlet holes 43 are arranged at equal intervals along a third direction, which is parallel to the height direction of the disc body. The spacing between adjacent first water outlet holes 43 can be adjusted according to actual water distribution requirements and installation space.

[0083] In this embodiment, the multiple first water outlet holes 43 are arranged at equal intervals, which can improve the water outlet uniformity of the first energy-consuming part 41 along the height direction of the disc body 1, and help to make the water flow more evenly distributed in the water distribution area 11, thereby improving the water distribution uniformity of the water distribution system.

[0084] refer to Figure 2 and Figure 3 In some embodiments, there are multiple second water outlet holes 44. The second water outlet holes 44 include, but are not limited to, 3 to 5 rows distributed vertically, with the number of second water outlet holes 44 in each row determined according to the dimensions of the second energy-consuming part 42. The spacing and arrangement of adjacent second water outlet holes 44 can be adjusted according to actual conditions.

[0085] In this embodiment, by setting multiple second water outlet holes 44 to form a multi-point distribution, the ability to disperse water flow can be increased, which helps to improve the adjustment stability of the adjustment zone 12 and reduce the situation where water flow splashes due to water flow impacting the end face of the disc 1 adjacent to the second energy consumption part 42.

[0086] refer to Figure 2 and Figure 3In some embodiments, multiple second water outlets 44 are arranged at equal intervals along a third direction and / or a first direction, with the third direction parallel to the height direction of the disc body. The spacing between adjacent second water outlets 44 can be adjusted according to actual water distribution requirements and installation space.

[0087] In this embodiment, the multiple second water outlet holes 44 are arranged at equal intervals, which can improve the water outlet uniformity of the second energy-consuming part 42 along the height direction and / or length direction of the disc 1, and help to make the water flow more evenly distributed in the adjustment zone 12, thereby improving the adjustment reliability of the adjustment zone 12.

[0088] refer to Figure 1 and Figure 3 In some embodiments, the water supply device 3 includes a water supply pipe disposed on the first end face 13 of the disc body 1, the water supply pipe extending along a first direction. Preferably, the water supply pipe is disposed at the center of the disc body 1 along the width direction of the disc body 1.

[0089] The first end face 13 of the disc body 1 refers to the end face of the disc body 1 that is close to the energy-consuming device 4 and the water supply device 3. A mounting hole is provided on the first end face 13 of the disc body 1, and the water supply pipe is installed on the end face of the disc body 1 through the mounting hole. The pipe opening is opposite to the first water outlet 43, and the second water outlet 44 is located on the side of the water supply pipe.

[0090] In this embodiment, by setting the water supply pipe to extend along the first direction, the water flow provided by the water supply pipe flows toward the first energy dissipation part 41, thus avoiding the situation where the water flowing out of the water supply pipe flows directly out of the second water outlet 44 without impacting and dissipating energy with the first energy dissipation part 41. As a result, the water flowing from the second water outlet 44 to the regulating zone 12 has lower kinetic energy after secondary energy dissipation, reducing the risk that the water at the far end of the water distribution zone 11 cannot overcome the water flow resistance in the regulating zone 12 and cannot flow back from the regulating zone 12 under high flow conditions. This improves the reliability of the water flow at the far end of the water distribution zone 11 flowing back from the regulating zone 12 under high flow conditions and enhances the regulating stability of the regulating zone 12.

[0091] refer to Figure 1 and Figure 3 In some embodiments, the opening of the water supply pipe is higher than the first water outlet 43 and / or the second water outlet 44.

[0092] In this embodiment, by setting the opening of the water supply pipe higher than the first water outlet 43 and / or the second water outlet 44, the risk of water splashing caused by the high-speed jet provided by the water supply pipe flowing directly out of the first water outlet 43 without impacting and consuming energy with the first energy-consuming part 41 can be reduced, as can the risk of water splashing caused by the water flowing directly out of the second water outlet 44 without impacting the second energy-consuming part 42 can be reduced, and the situation of water not flowing smoothly under low flow conditions can be reduced.

[0093] refer to Figure 2 In some embodiments, the bottom of the first energy-consuming part 41 is connected to the first end face 13 of the disc body 1 and is inclined relative to the first end face 13 of the disc body 1, so that the water flowing out of the first water outlet 43 can flow to the projection area of ​​the first energy-consuming part 41 on the bottom surface of the disc body 1.

[0094] In this embodiment, the first energy-consuming part 41 is inclined relative to the first end face 13 of the disc body 1, which can reduce the obstruction of the spray hole 110 by the first energy-consuming part 41, facilitate the water output of the spray hole 110 and the installation and maintenance of the spray hole 110, and improve the uniformity and reliability of water distribution.

[0095] refer to Figure 2 In some embodiments, the angle between the first energy-consuming part 41 and the first end face 13 of the disc 1 ranges from 45° to 75°. In this embodiment, setting the angle between the first energy-consuming part 41 and the first end face 13 of the disc 1 to 45° or 75° can achieve a better energy-consuming effect with a fixed height of the disc 1 and facilitate production and installation. This reduces the impact on installation and increased production costs caused by the first energy-consuming part 41 being too long, and the situation where the first energy-consuming part 41 is too short, resulting in a distance too close to the water outlet of the water supply device 3, making it difficult to repeatedly impact and consume energy with water.

[0096] refer to Figure 1 , Figure 4A and Figure 4B In some embodiments, there are two flow guides 2, spaced apart along the second direction, to divide the disc body 1 into a water distribution area 11 and two adjustment areas 12. There are two second energy dissipation parts 42, which are spaced apart along the second direction on both sides of the first energy dissipation part 41.

[0097] In this embodiment, in order to further enhance the adjustment capability, the number of flow guides 2 is set to two, and the disc body 1 has two adjustment zones 12, which can enhance the adjustment capability under different flow conditions, thereby improving the uniformity of water distribution.

[0098] refer to Figures 1-3 In some embodiments, the energy-consuming device 4 further includes a sealing plate 45, which is connected to the top of the first energy-consuming part 41 and the two second energy-consuming parts 42 respectively, so as to form an energy-consuming cavity with the first energy-consuming part 41, the two second energy-consuming parts 42 and the first end face 13 of the disk body 1.

[0099] The sealing plate 45 covers the top of the first energy-consuming part 41 and the second energy-consuming part 42, forming a partially closed energy-consuming cavity with the first energy-consuming part 41, the two second energy-consuming parts 42 and the first end face 13 of the disk body 1.

[0100] The inlet of the water supply pipe is located inside the energy dissipation chamber. After the water flow collides with the first energy dissipation part 41, it can undergo multiple tumbling and energy dissipation within the energy dissipation chamber. The water flow after impact energy dissipation is confined within the energy dissipation chamber, which can reduce water splashing and overflow abnormalities.

[0101] The sealing plate 45 includes, but is not limited to, the first end face 13 perpendicular to the disk body 1 for easy installation. The first energy-consuming part 41 and the second energy-consuming part 42 are, but are not limited to, vertically arranged. The sealing plate 45, the first energy-consuming part 41 and the second energy-consuming part 42 form a prism-shaped energy-consuming box, which has good structural stability and is easy to process.

[0102] In this embodiment, by setting the sealing plate 45 to form an energy dissipation cavity, the water flow after energy dissipation can be constrained, reducing water splashing and overflow abnormalities, and improving the reliability of water distribution.

[0103] refer to Figure 1 In some embodiments, the height of the guide member 2 is higher than the rated water level of the disc body 1. The rated water level of the disc body 1 corresponds to the water level height inside the disc body 1 at the rated water supply. The height of the guide member 2 includes, but is not limited to, being lower than the height of any second water outlet 44, in order to reduce interference with the second water outlet 44.

[0104] In this embodiment, the height of the guide 2 is set to be higher than the rated water level of the disc body 1, so that the water distribution area 11 and the regulating area 12 can be isolated, allowing the regulating area 12 to effectively play its regulating role, thereby improving the reliability of water distribution.

[0105] When operating under overload, the water level in the disc 1 will reach 110% of the rated water level. If it operates for a long time, dirt will clog the spray holes 110, and the water level will approach 120% of the rated water level. The height of the guide 2 is preferably higher than 120% of the rated water level of the disc 1 to ensure that the regulating zone 12 and the water distribution zone 11 can be separated along the width direction under high flow conditions, so that the water flow regulating function of the regulating zone 12 can be normal.

[0106] refer to Figure 1 , Figure 4A and Figure 4B In some embodiments, the second energy-consuming part 42 is arranged parallel to the first direction and abuts against the end of the guide member 2. The height of the guide member 2 includes, but is not limited to, being lower than the height of any second water outlet 44, in order to reduce interference with the water outlet of the second water outlet 44.

[0107] In this embodiment, the second energy-consuming part 42 is arranged parallel to and abuts against the flow guide 2, which can restrict the water flow path and effectively separate the water flow from the first water outlet 43 and the water flow from the second water outlet 44 at the first interval 51, thereby further improving the water flow balance capability.

[0108] Combination Figures 1-3 , Figure 4A and Figure 4B The following provides a more detailed description of the structure of the water distribution system in some embodiments:

[0109] The water supply device 3 includes a water inlet pipe, and the energy consumption device 4 includes an energy consumption box. A through hole of the same diameter as the water inlet pipe is opened at the center of the first end face 13 of the plate body 1, and is located between the water inlet pipe and the energy consumption box. Cooling water flows horizontally through the water inlet pipe, the first end face 13 of the plate body 1, and the energy consumption box in sequence.

[0110] The energy-consuming box includes a first energy-consuming part 41, a second energy-consuming part 42, a sealing plate 45, a first water outlet 43, and a second water outlet 44. The energy-consuming box and the first end face 13 of the disc body 1 form a triangular prism-shaped energy-consuming cavity. The high-pressure water flow from the inlet pipe enters the energy-consuming cavity after passing through the through hole of the first end face 13 of the disc body 1, and is transformed into a high-speed impact jet. The jet impacts and disperses with the first energy-consuming part 41 and the second energy-consuming part 42, and the impact force of the water flow decreases.

[0111] The first energy-consuming part 41 is positioned facing the direction of water flow and is inclined relative to the first end face 13 of the disc body 1 at an angle of 45° to 75°. After the high-speed jet collides with the first energy-consuming part 41, it flips upward to further reduce the impact force of the water flow.

[0112] The first energy-consuming part 41 has a first water outlet 43, which includes 3 to 5 rows of long slot-shaped openings to retain the kinetic energy of the water flow in the inlet direction and increase the water delivery distance under the large-span plate 1. The height of the first water outlet 43 is lower than the height of the inlet pipe to prevent high-speed jets from flowing directly out of the energy-consuming box and causing water droplets to splash.

[0113] The second energy-consuming part 42 is located at both ends of the energy-consuming box and is parallel to the water flow direction. After the impact jet consumes energy by colliding with the first energy-consuming part 41, it undergoes a second impact at the second energy-consuming part 42 to consume energy and decelerate.

[0114] The top of the energy-consuming box is equipped with a sealing plate 45, which can confine the water flow after impact energy consumption within the cavity of the energy-consuming box to prevent droplet splashing and abnormal overflow. The second energy-consuming part 42 has a second water outlet 44, which includes 3 to 5 rows of circular openings. The circular openings have higher energy consumption intensity and stronger water flow dispersion ability than the long groove openings, and can provide lower speed side water discharge.

[0115] The disc body 1 includes a bottom surface and a first end surface 13, a second end surface 14, a third end surface 15, and a fourth end surface 16 perpendicular to the bottom surface, forming a long and narrow water distribution cavity with an aspect ratio greater than 4. The first end surface 13 and the second end surface 14 are spaced apart along the length direction, with the first end surface 13 located on the side closer to the energy dissipation device 4.

[0116] The height of the guide 2 is greater than the design water level when the rated water volume is 120%. It is installed on both sides of the bottom surface along the length direction, with a gap between it and the third end face 15 and the fourth end face 16, thereby dividing the disc body 1 in the width direction into a water distribution area 11 near the middle and an adjustment area 12 on both sides, and the width of the water distribution area 11 is greater than the width of the adjustment area 12.

[0117] The bottom surface of the disc 1 has spray holes 110 evenly distributed only in the water distribution area 11. The spray holes 110 can be equipped with variable flow high-efficiency spray heads. No spray holes 110 are opened in the adjustment area 12, so that after the low-speed water enters the adjustment area 12, the water flow will not be dispersed by the spray holes 110, and it can be directly connected to the water distribution area 11 at the far end.

[0118] The inlet of the water distribution zone 11 and the inlet of the regulating zone 12 are both located at the near end of the water inlet on the first end face 13, and the outlet of the water distribution zone 11 and the outlet of the regulating zone 12 are both located at the far end of the water inlet on the second end face 14.

[0119] The first water outlet 43 of the energy-consuming box is directly opposite the inlet of the water distribution zone 11, so that the water flowing into the water distribution zone 11 can retain more horizontal kinetic energy; the second water outlet 44 is sideways to the inlet of the regulating zone 12, so that the water flowing into the regulating zone 12 is more dispersed and has a lower flow rate.

[0120] Figure 5 This is a water distribution velocity distribution cloud map based on some embodiments of the water distribution system disclosed herein. Figure 6 This is a velocity vector diagram within a water distribution device according to some embodiments of the water distribution system disclosed herein. Figure 7 This is a schematic diagram of the liquid level of a water distribution device according to some embodiments of the water distribution system disclosed herein. Figures 5-7 All of these are water distribution conditions under the rated water supply capacity.

[0121] refer to Figure 5 Different colors on the left-hand scale correspond to different water flow rates. The flow rate provided by water supply device 3 is... Figure 5 The velocity of the water outlet is shown in dark orange, approximately 2 m / s. Five rows of first water outlets 43 are formed on the first energy-consuming part 41. The water flow velocity in most areas of the first water outlets 43 is shown in green, approximately 1.2 m / s. The first row of first water outlets 43 located at the top has a higher flow velocity due to its proximity to the high-pressure water jet from the water supply device 3. Figure 5 The reading is dark yellow, approximately 1.5 m / s; the energy dissipation chamber is not completely filled with water, and there is some overturned water flow near the top of the chamber, blocked by the sealing plate 45. Figure 5 The area shown is green, approximately 1.2 m / s, and includes some waterless areas. Figure 5 It is shown in blue, and its speed is approximately 0 m / s.

[0122] refer to Figure 6 The vector arrows on the left represent the water flow pattern, and the color of the arrows indicates the velocity value. Figure 6 The water flow velocity in the green area is greater than that in the blue area, and the water flow velocity in the blue area is greater than that in the purple area. Figure 6 The area on the left is where the energy-consuming device 4 is located. The water flow in the water distribution zone 11 exhibits a flow pattern that concentrates in the middle and sparses on both sides, which is consistent with the characteristic of setting the first water outlet 43 as a long trough to retain the flow potential energy, allowing the water flow to reach the far end. Although the water flow concentration trend decreases along the way from the near end to the far end, it is not completely eliminated at the far end, indicating that there is excess kinetic energy in the water flow at the far end. The water flow in the regulating zones 12 on both sides is gentle and stable, and at the rated flow rate, the excess water at the far end of the water distribution zone 11 flows back to the near end from the regulating zone 12.

[0123] refer to Figure 7 In the diagram, red represents the water phase, blue represents the air phase, and the critical point is the gas-water interface. Figure 7 The area on the left side is where the energy-consuming device 4 is located. Under stable conditions, the liquid level in the disc 1 is relatively uniform at the near and far ends, and the liquid surface is stable without significant disturbance.

In this embodiment, the water distribution system of the cooling tower has a strong ability to uniformly distribute water, which helps to improve the cooling spray effect and heat exchange performance of the cooling tower.
