Liquid distribution mechanism and cooling tower

Abstract

This invention relates to a liquid distribution mechanism and a cooling tower. The liquid distribution mechanism includes a liquid distribution component and a driving component. The liquid distribution component has at least one liquid distribution structure, which is used to receive and spray coolant from the liquid distribution structure. The driving component is drively connected to the liquid distribution component and is used to drive the liquid distribution component to displace at least a portion of the liquid distribution structure. In the above-mentioned liquid distribution mechanism, the liquid distribution component receives the coolant and sprays the coolant from the liquid distribution structure. Because the liquid distribution component is driven by the driving component, the liquid distribution structure is displaced accordingly, and the sprayed area changes continuously during this process. Therefore, the spray concentration of the liquid distribution mechanism is significantly reduced, allowing for a wider range of liquid distribution to the condenser, resulting in more thorough spray coverage. On the other hand, due to the reduced spray concentration, the coolant can form a thinner liquid film on a larger surface area of ​​the condenser, making fuller use of the coolant phase change to absorb heat from the condenser and improving heat exchange efficiency.

Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, and in particular to a liquid distribution mechanism and a cooling tower. Background Technology

[0002] With the increasing mining of coal, my country's shallow coal resources are gradually decreasing, while mining depths are continuously increasing. The annual mining depth of key state-owned coal mines has increased by 9 meters, with the deepest mines reaching 1000 meters. According to measurements from around the world, the global average geothermal gradient is approximately 3℃ / 100m. The main causes of heat in coal mines in major regions of China include rock temperature increases with mining depth and heat dissipation from large mechanical and electrical equipment. Heat hazards not only worsen the working environment of coal mining but also increase the frequency of coal mine accidents.

[0003] In existing technologies, closed-loop cooling towers are used for cooling and temperature reduction. To improve efficiency and cooling effect, these towers utilize water pumps and pipes to spray water onto the surface of their condensers to promote heat exchange. However, in current closed-loop cooling towers, the water sprayed onto the condenser surface is concentrated and fixed, resulting in insufficient spraying effect and limited contribution to improving the condenser's heat exchange efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid distribution mechanism and cooling tower that can fully spray the condenser to address the above problems.

[0007] A driving component, which is connected to the liquid distribution component, is used to drive the liquid distribution component to displace at least a portion of the liquid distribution structure thereon.

[0008] The aforementioned coolant distribution mechanism receives coolant from a distribution component and sprays it out from a distribution structure. Because the distribution component is driven by a drive component, the distribution structure on it moves accordingly. During this displacement, the spraying area continuously changes. Therefore, the spray concentration of the mechanism is significantly reduced, allowing for wider distribution of coolant to the condenser and more thorough coverage.

[0009] In one embodiment, the driving component is a water turbine, which is driven by the coolant. The coolant flows in from the inlet of the water turbine, flows out from the outlet, and is received by the liquid distribution component.

[0010] In one embodiment, the liquid distribution mechanism further includes a fan that is drivenly connected to the water turbine.

[0011] In one embodiment, the drive is configured to drive the liquid distribution member to rotate about a pivot, and the pivot is spaced apart from at least a portion of the liquid distribution structure.

[0012] In one embodiment, the liquid distribution component includes an umbrella-shaped liquid distribution plate that receives the coolant through an umbrella opening, and all the liquid distribution structures are liquid distribution holes formed on the umbrella-shaped liquid distribution plate.

[0013] In one embodiment, the umbrella-shaped liquid distribution plate has multiple sets of liquid distribution holes, each set of liquid distribution holes including multiple liquid distribution holes distributed radially along the umbrella-shaped liquid distribution plate.

[0014] In one embodiment, the liquid distribution component further includes a partition plate disposed on the surface of the umbrella-shaped liquid distribution plate for receiving the coolant, and the partition plate is disposed between every two adjacent groups of liquid distribution holes.

[0015] In one embodiment, the liquid distribution mechanism further includes a transmission component, through which the drive component drives the liquid distribution component to rotate at a speed different from its output speed.

[0016] In one embodiment, the transmission component is a planetary gear, with the sun gear of the planetary gear being the driving force and connected to the output shaft of the drive component, and the planet carrier of the planetary gear being the driven force and connected to the liquid distribution component.

[0035] Please see Figures 1 to 3 An embodiment of the present invention provides a cooling tower 100, including a liquid distribution mechanism 10, which is used to spray coolant onto the condenser 30 in the cooling tower 100.

[0036] When the cooling tower 100 is working, the refrigerant used for cooling absorbs heat and is then cooled in the condenser 30. Spraying coolant onto the surface of the condenser 30 helps with cooling and heat dissipation, improving the efficiency and cooling effect of the cooling tower 100. The coolant can be, but is not limited to, water or other heat exchange media. Before distribution, the coolant is in a liquid state for easy distribution; upon reaching the surface of the condenser 30, it undergoes a phase change to more fully absorb heat from the condenser 30.

[0037] Understandably, the liquid distribution mechanism 10 is arranged above the condenser 30 to facilitate liquid distribution to the condenser 30. The cooling tower has a liquid storage tank 50, which is located below the condenser 30 to receive the coolant dripping from above. The liquid storage tank 50 has an outlet Y, and the cooling tower 100 also has a spray pump 71 and a delivery pipe 73 for pumping coolant from the outlet Y of the liquid storage tank 50 to the liquid distribution mechanism 10 above. In addition, the condenser 30 has an inlet L1 for inputting refrigerant and an outlet L2 for outputting refrigerant, etc., which will not be described in detail here. In this embodiment, the cooling tower 100 can be a closed-loop cooling tower 100 for mining.

[0038] Please refer to the following: Figures 4 to 7 An embodiment of the present invention also provides the above-described liquid distribution mechanism 10, including a liquid distribution component 11 and a driving component 13. The liquid distribution component 11 is configured with at least one liquid distribution structure (the liquid distribution hole K mentioned below is the liquid distribution structure), and the liquid distribution component 11 is used to receive and spray coolant from the liquid distribution structure. The driving component 13 is drively connected to the liquid distribution component 11 and is used to drive the liquid distribution component 11 to move at least a portion of the liquid distribution structure thereon.

[0039] The driving member 13 can drive the liquid distribution member 11 to perform actions such as, but not limited to, translation, rotation, or a combination of both. The liquid distribution structure is constructed on the liquid distribution member 11, and its form can be a hole penetrating the liquid distribution member 11 or a port located at the end of the liquid distribution member 11, as long as it allows the coolant received by the liquid distribution member 11 to flow out through it. To achieve uniform liquid distribution, multiple liquid distribution structures can be evenly arranged. When the driving member 13 drives the liquid distribution member 11, the liquid distribution structure constructed on the liquid distribution member 11 naturally moves accordingly. The coolant received by the liquid distribution member 11 is sprayed out from the liquid distribution structure. This spraying can be achieved under the action of gravity or driven by equipment such as a water pump; no specific limitation is made here.

[0040] The aforementioned liquid distribution mechanism 10 receives coolant from the liquid distribution component 11 and sprays the coolant out from the liquid distribution structure. Since the liquid distribution component 11 is driven by the drive component 13, the liquid distribution structure on it moves accordingly. During this displacement, the spraying area continuously changes. Therefore, the spray concentration of the liquid distribution mechanism 10 is significantly reduced, allowing for wider liquid distribution to the condenser 30, resulting in more thorough coverage. Furthermore, due to the reduced spray concentration, the coolant can form a thinner liquid film over a larger area of ​​the condenser 30 surface, more fully utilizing the phase change of the coolant to absorb heat from the condenser 30, improving the cooling efficiency of the coolant, and consequently, improving the heat exchange efficiency of the condenser 30.

[0041] Furthermore, the driving member 13 drives the liquid distribution member 11 to rotate about a rotating shaft, and the rotating shaft is spaced apart from at least part of the liquid distribution structure.

[0042] Thus, when the liquid distribution component 11 rotates around the axis, the liquid distribution structure on it also rotates around the axis, and the liquid distribution structure spaced apart from the axis will continuously shift and sweep across a range during the rotation around the axis.

[0043] In some embodiments, the drive unit 13 is a water turbine, which is driven by coolant. The coolant flows in from the inlet J of the water turbine and flows out from the outlet C, and is received by the liquid distribution unit 11.

[0044] The coolant flowing into the turbine at inlet J impacts its impeller, converting the kinetic energy of the coolant flow into rotational mechanical energy that can be output by the turbine, driving the rotation of the distribution element 11. After impacting the impeller, the coolant flows out from the turbine outlet C and flows to the distribution element 11, where it is received and becomes the coolant subsequently distributed to the condenser 30 by the distribution element 11. The kinetic energy of the coolant flow can come from the aforementioned spray pump 71, or it can be converted from gravitational potential energy due to changes in altitude during transport.

[0045] The liquid distribution mechanism 10 fully utilizes the kinetic energy naturally possessed by the flowing coolant through the water turbine to drive the liquid distribution component 11 to rotate, thereby completing the full spraying of coolant without the need for additional energy input.

[0046] Specifically, the turbine can be a mixed-flow turbine, from which coolant can flow in radially and out axially, with outlet C pointing downwards. The liquid distribution component 11 is located below the turbine to receive the coolant discharged from outlet C.

[0047] Please refer to the following: Figure 8 and Figure 9 In some embodiments, the liquid distribution component 11 includes an umbrella-shaped liquid distribution plate 111 that receives coolant through an opening, and all liquid distribution structures are liquid distribution holes K formed on the umbrella-shaped liquid distribution plate 111. In the direction of gravity, the opening of the umbrella-shaped liquid distribution plate 111 faces upward.

[0048] The umbrella-shaped liquid distribution plate 111 has its opening facing the water turbine, and the water turbine's outlet C is aligned with the central area of ​​the umbrella-shaped liquid distribution plate 111. The liquid distribution hole K penetrates the umbrella-shaped liquid distribution plate 111. Coolant first falls through the opening into the central area of ​​the umbrella-shaped liquid distribution plate 111, and then, as the umbrella-shaped liquid distribution plate 111 rotates, it passes through the liquid distribution hole K and falls downwards into the condenser 30, with the falling position constantly changing during rotation. Understandably, the axis of the umbrella-shaped liquid distribution plate 111 is coaxially arranged with the rotating shaft of the liquid distribution component 11 to ensure stable rotation.

[0049] The umbrella-shaped liquid distribution plate 111 is convenient for receiving coolant, and its umbrella-shaped structure gives it a certain storage capacity. During rotation, the coolant it receives is sprayed from the liquid distribution port into the condenser 30 below.

[0050] Understandably, in some other embodiments, in addition to the umbrella-shaped liquid distribution plate 111, the structure for receiving coolant can also be a hollow spray arm, etc., as long as it can receive coolant and guide it to the liquid distribution structure to complete the liquid distribution, and can be driven to rotate by a water turbine.

[0051] Furthermore, multiple sets of liquid distribution holes are provided on the umbrella-shaped liquid distribution plate 111, and each set of liquid distribution holes includes multiple liquid distribution holes K distributed radially along the umbrella-shaped liquid distribution plate 111.

[0052] Understandably, each set of liquid distribution holes extends radially along the umbrella-shaped liquid distribution disk 111. Therefore, it is preferable that multiple sets of liquid distribution holes are evenly arranged around the axis of the umbrella-shaped liquid distribution disk 111.

[0053] Each distribution hole K on the umbrella-shaped liquid distribution plate 111 represents a liquid distribution area, which corresponds to a liquid distribution range on the condenser 30. Multiple distribution holes K are formed radially along the umbrella-shaped liquid distribution plate 111 to form a group of distribution holes, and multiple groups of distribution holes are formed circumferentially along the umbrella-shaped liquid distribution plate 111. This helps to form a larger liquid distribution range on the condenser 30 and to distribute the liquid to the condenser 30 fully and evenly during rotation.

[0054] Furthermore, the liquid distribution component 11 also includes a partition 113, which is disposed on the surface of the umbrella-shaped liquid distribution plate 111 for receiving coolant, and a partition 113 is provided between every two adjacent groups of liquid distribution holes.

[0055] The umbrella-shaped distribution plate 111 is the surface to which the coolant falls and flows, specifically the surface facing the turbine. Constrained by the baffles 113, the coolant on the umbrella-shaped distribution plate 111 rotates with it. During rotation, the coolant, under the action of centrifugal force, overcomes gravity and moves radially along the umbrella-shaped distribution plate 111. Two adjacent baffles 113 effectively define a coolant flow channel F. At this time, the distribution holes K are located on the coolant's movement path, and the coolant passes through the distribution holes K at different positions during its movement to complete the distribution.

[0056] Specifically, each baffle 113 extends from the axis of the umbrella-shaped liquid distribution plate 111 to its periphery, and the side of the baffle 113 facing away from the surface of the umbrella-shaped liquid distribution plate 111 used to receive coolant is flush with the opening of the umbrella-shaped liquid distribution plate 111.

[0057] All baffles 113 extend from the axis of the umbrella-shaped liquid distribution plate 111 to the periphery, forming a complete coolant flow channel F on the surface of the umbrella-shaped liquid distribution plate 111. The coolant falling into the central area of ​​the umbrella-shaped liquid distribution plate 111 is separated by the baffles 113 and enters each flow channel, and flows along the flow channel during rotation to complete the liquid distribution.

[0058] Since the coolant falls directly onto the central area of ​​the umbrella-shaped distribution plate 111, the closer to the axis, the higher the coolant level is relative to the surface of the umbrella-shaped distribution plate 111. The height of the baffle 113 in the direction of gravity is flush with the opening of the umbrella-shaped distribution plate 111. Relative to the surface of the umbrella-shaped distribution plate 111, the baffle 113 gradually increases in height along the direction closer to the axis of the umbrella-shaped distribution plate 111 to fully accommodate the distribution characteristics of the coolant.

[0059] In some embodiments, the liquid distribution mechanism 10 further includes a fan 15, which is connected to the water turbine drive.

[0060] The fan 15 can be directly mounted on the output shaft of the water turbine, and can be considered as forming a hydraulic fan together with the water turbine. Understandably, the fan 15 outputs cooling air to the condenser 30. On one hand, the fan 15 can drive airflow to generate cooling air, thereby enhancing the convective heat transfer intensity between the air and the condenser 30. On the other hand, the cooling air generated by the fan 15 can also enhance the phase change effect of the liquid film formed by the coolant on the surface of the condenser 30, further improving the cooling efficiency of the coolant on the condenser 30. Thus, liquid cooling and air cooling are combined, complementing each other, and jointly improving the heat exchange efficiency of the condenser 30.

[0061] Understandably, to avoid obstructing the flow path of the coolant, the fan 15 is positioned on the side of the turbine away from the coolant distribution member 11. In other words, the fan 15 is positioned above the turbine, and the coolant distribution member 11 is positioned below the turbine, with both connected to the turbine drive from their respective sides.

[0062] In some embodiments, the liquid distribution mechanism 10 further includes a transmission component (the planetary gear 17 described below is the transmission component), and the drive component 13 drives the liquid distribution component 11 to rotate at a speed different from its output speed through the transmission component.

[0063] On the one hand, the coolant distribution component 11 can be more flexibly and stably connected to the drive component 13 via a transmission component. On the other hand, the rotational speed output by the drive component 13 may not be suitable for coolant distribution, so the coolant distribution component 11 can be driven to rotate at a suitable speed by increasing or decreasing speed through a transmission component. The rotational speed of the coolant distribution component 11 should be such that the coolant on the umbrella-shaped distribution plate 111 is fully distributed to the entire umbrella-shaped distribution plate 111 without overflowing from the periphery.

[0064] Especially for the water turbine, which serves as the driving component 13, when it drives both the fan 15 and the liquid distribution component 11 to rotate under the influence of coolant, there is a significant difference in the required rotational speeds of the fan 15 and the liquid distribution component 11. To generate sufficient cooling air, the fan 15 typically rotates at a relatively high speed, possibly reaching 700 r / min, which is roughly the same as the output speed of the coolant-driven water turbine. Therefore, the fan 15 can be directly mounted on the output shaft of the water turbine. However, the umbrella-shaped liquid distribution plate 111 requires a relatively slower rotational speed, thus necessitating a transmission connection with the water turbine's rotational speed via a transmission component.

[0065] Furthermore, the transmission component is a planetary gear 17, with the sun gear 171 of the planetary gear 17 being the driving force and connected to the output shaft of the drive component 13, and the planet carrier 173 of the planetary gear 17 being the driven force and connected to the liquid distribution component 11. Specifically, the planet carrier 173 and the liquid distribution component 11 are connected by a connector 179.

[0066] Understandably, the planetary gear 17 also includes an external gear ring 177 and planetary gears 175 connected to the planet carrier 173, which will not be described in detail here. The fluid distribution component 11 rotates with the planet carrier 173, which is driven by the sun gear 171 through the planetary gears 175. Therefore, the rotational speed output from the output shaft of the drive component 13 is transmitted to the fluid distribution component 11 after being reduced by the planetary gear 17.

[0067] Taking a water turbine with an output speed of 700 r / min as an example, the transmission ratio of planetary gear 17 is 7, and the speed of liquid distribution component 11 is 100 r / min.

[0068] The aforementioned liquid distribution mechanism 10 utilizes the kinetic energy of the coolant flow via a water turbine to drive the liquid distribution component 11 and the fan 15 to rotate. The liquid distribution component 11 is connected to the water turbine via a planetary gear 17 for speed reduction relative to the fan 15. During the liquid distribution process to the condenser 30, the liquid distribution component 11 is driven to rotate by the water turbine, and the coolant flowing through the turbine falls into the umbrella-shaped liquid distribution plate 111. The coolant on the umbrella-shaped liquid distribution plate 111 rotates fully under the action of the baffle 113. At this time, under the action of centrifugal force, the coolant overcomes gravity and moves radially from the center area to the periphery along the umbrella-shaped liquid distribution plate 111, continuously passing through the distribution holes K along the path and falling onto the condenser 30, thus uniformly completing the liquid distribution. The coolant falling onto the condenser 30 forms a liquid film on the condenser 30, exchanging heat with the condenser 30 and undergoing a phase change to fully absorb heat. On the other hand, the cooling air generated by the fan 15 enhances the convective heat transfer intensity between the air and the condenser 30, and also enhances the phase change effect of the coolant.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
