Description

Technical Field

[0001] This utility model belongs to the field of cooling tower technology, specifically relating to a cooling tower splash-proof material. Background Technology

[0002] Cooling towers are common heat dissipation devices in industrial production. They use water as a refrigerant and have an internal packing structure to increase heat dissipation, extend the residence time of cooling water, increase the heat exchange area, and increase the heat exchange capacity. Cooling tower packing is usually made of materials such as PVC, PP, or fiberglass, and has the characteristics of being lightweight, corrosion-resistant, high-temperature resistant, and not prone to scaling.

[0003] In practice, to ensure the service life of cooling tower packing and to ensure that the cooling tower packing is in the best heat exchange condition, the cooling tower packing is usually installed in a way that is easy to maintain.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN222718787U discloses "a cooling tower packing with a quick disassembly and assembly structure", which includes components such as a guide channel, splicing channel, splicing clamp, and lower fixing plate. The device adopts a cleaning hole design, which allows water flow to directly flush the gaps of the guide channel, quickly disperse and remove tiny scale particles in the water, and effectively prevent them from forming scale on the surface of the packing.

[0005] While existing cooling tower packing materials, including those mentioned above, can meet general usage requirements, in actual use, the design purpose of cooling tower packing materials is to distribute water flow evenly into a thin film to maximize the contact area between water and air. However, with existing cooling tower packing materials, there is a possibility of splashing when water flows into the packing material, causing water to pass through the packing material quickly in the form of droplets, reducing the water film coverage area and lowering heat exchange efficiency. If violent splashing occurs, it may interfere with the air flow within the packing layer (such as forming turbulence or local resistance), further weakening the heat dissipation effect.

[0006] To address the aforementioned problems, this utility model proposes a cooling tower splash-proof material. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-4 The present invention provides the following technical solution: a cooling tower anti-splash material, including a fixed box 1 and a packing body 2 installed in the fixed box 1, further including a flow guide shroud 3 fixed to the top of the fixed box 1 and a flow guide plate 5 installed in the flow guide shroud 3 by means of a buffer assembly 6, wherein a plurality of equally spaced flow guide holes 51 are provided on the flow guide plate 5, wherein the buffer assembly 6 includes: a fixed frame 61, a guide column 62 and a telescopic spring 63.

[0039] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, the fixing frame 61 is fixed inside the guide shroud 3, the guide post 62 passes through the fixing frame 61, and the guide plate 5 is fixed to the top of the guide post 62. The telescopic spring 63 is sleeved on the guide post 62 and is located between the guide plate 5 and the fixing frame 61. With the above scheme, when the cooling water falls from the upper spray system of the cooling tower, it first enters the guide area of ​​the guide shroud 3. The high-speed falling water impacts the surface of the guide plate 5. Since the guide plate 5 is elastically connected to the guide shroud 3 through the buffer component 6, the impact force of the water will drive the guide plate 5 to move downward along the guide post 62, compressing the telescopic spring 63 sleeved on the guide post 62. In this process, the telescopic spring 63 absorbs the impact energy of the water flow through elastic deformation, converting kinetic energy into elastic potential energy, effectively reducing the rigid impact of the water flow on the guide plate 5, thereby reducing the splashing phenomenon caused by the impact.

[0040] When the dispersed water flow passes through the evenly distributed guide holes 51 on the guide plate 5, it is divided into multiple thin streams, thus achieving initial water distribution.

[0041] The evenly spaced design of the guide holes 51 ensures that the water flow is evenly distributed on the cross-section, avoiding local water concentration. As the guide plate 5 moves downward due to the impact of the water flow, the compression reaction force of the telescopic spring 63 gradually increases. When the impact force of the water flow and the spring force reach a dynamic balance, the guide plate 5 stops moving downward and maintains a stable buffer state. At this time, the guide holes 51 and the water inlet surface of the packing body 2 form the optimal guiding angle, so that the water flow falls vertically into the heat dissipation area of ​​the packing body 2 at a steady speed.

[0042] When the spray water volume changes, the adaptive characteristics of the buffer assembly 6 come into play: if the water volume increases, resulting in a stronger impact force, the guide plate 5 will further compress the telescopic spring 63 to absorb more impact energy by increasing the buffer stroke; if the water volume decreases, the elastic restoring force of the telescopic spring 63 will push the guide plate 5 to return to its original position along the guide post 62.

[0043] Throughout the entire operation, the guide shroud 3 plays a preliminary role in converging the water flow, the buffer component 6 attenuates the impact energy of the water flow through an elastic buffering mechanism, and the guide plate 5, together with the guide hole 51, achieves uniform water distribution. The three work together to ensure that the cooling water enters the packing body 2 in a stable and uniform state. The packing body 2 further disperses the water flow into a water film or water droplets, increasing the contact area with air and improving the heat exchange efficiency. At the same time, because the impact energy is effectively absorbed, the splashing phenomenon of the water flow when entering the packing is significantly suppressed, reducing the loss of cooling water and improving the overall performance of the cooling tower.

[0044] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the guide plate 5 is a "human" shaped plate. After adopting the above scheme, when in use, the structural feature of the "human" shaped plate being high in the middle and low on both sides causes the falling water flow to automatically split to the left and right sides when it impacts the plate surface.

[0045] This diversion mechanism, combined with the evenly spaced distribution of the guide holes 51, can transform the concentrated water jet into a water film that is evenly spread along the herringbone slope. Compared with the planar guide plate 5, the water film has a larger contact area with the plate surface and a slower flow velocity during the flow process, which effectively reduces the rebound force generated by the vertical impact of the water flow and reduces the splashing phenomenon of water droplets caused by high-speed collision from the source. At the same time, the low slope design on both sides ensures that the water flow is initially homogenized before reaching the guide holes 51, avoiding the problem of some guide holes 51 exceeding the flow limit due to the concentration of water flow in the planar structure, and further suppressing water splashing at the orifice.

[0046] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, multiple guide posts 62 are evenly distributed along the length of the fixing frame 61. With the above solution, multiple guide posts 62 are used to support and guide the guide plate 5 during use, which further improves the stability of the guide plate 5 and avoids the guide plate 5 from rotating unexpectedly.

[0047] In addition, multiple guide pillars 62 evenly support the guide plate 5, avoiding the problem of deformation of the guide plate 5 due to water flow impact caused by local stress concentration.

[0048] Preferably, by Figure 1 and Figure 2As shown in this embodiment, the buffer assembly 6 further includes a limiting disk 64, which is fixed to the bottom end of the guide post 62. With the above solution, the limiting disk 64 is designed to limit the movement range of the guide plate 5 during use, so as to prevent the guide plate 5 from detaching from the fixing frame 61.

[0049] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it further includes: a water distribution plate 4, which is fixed inside the flow guide shroud 3 and located below the fixing frame 61. Water distribution holes 41 are evenly opened on the water distribution plate 4. After adopting the above scheme, when the water flow is initially dispersed through the flow guide holes 51 of the flow guide plate 5, the water flow carrying the remaining kinetic energy will vertically impact the water distribution plate 4 below. The water distribution plate 4 is a secondary water distribution element fixed inside the flow guide shroud 3. Its evenly distributed water distribution holes 41 and flow guide holes 51 form a "double-layer screening" structure.

[0050] When the water flow impacts the water distribution plate 4, some of the kinetic energy is converted into lateral diffusion energy along the plate surface, causing the water flow to form a uniform water film layer around the water distribution hole 41.

[0051] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the water distribution hole 41 is an "S" shaped hole. After adopting the above scheme, when in use, the upper and lower double-bend sections of the "S" shaped hole form a flow guiding channel. When the water flows through, it needs to undergo two directional deflections, which further reduces the water flow velocity and prevents the water flow from passing through the packing body 2 at a relatively fast speed. This is conducive to forming a uniform water film layer and improving the heat exchange efficiency.

[0052] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes: a flip cover plate 7, which is hinged to the bottom of the fixed box 1, and water outlet holes 71 are evenly opened on the flip cover plate 7. After the flip cover plate 7 is closed, it is locked with the fixed box 1 by the locking mechanism 8. With the above solution, when it is necessary to clean, replace or inspect the packing body 2, the restriction of the locking mechanism 8 can be released and the flip cover plate 7 can be opened, which is convenient for maintenance.

[0053] Optionally, by Figure 1 and Figure 4As shown, in this embodiment, the locking mechanism 8 includes a threaded rod 81, a fixing block 82, and a locking nut 83. The threaded rod 81 is hinged to the free end of the flip cover 7. The fixing block 82 is fixed to the outer wall of the fixing box 1, and a through hole 821 for the threaded rod 81 to pass through is provided on the fixing block 82. The locking nut 83 is installed on the protruding end of the threaded rod 81 by threaded engagement. With the above scheme, when locking, first close the flip cover 7, then flip the threaded rod 81 up so that the threaded rod 81 passes through the through hole 821, and finally tighten the locking nut 83 at the protruding end of the threaded rod 81. At the same time as tightening the locking nut 83, the threaded rod 81 pulls up the free end of the flip cover 7 under the threaded engagement, ensuring the stability of the flip cover 7 after it is closed.

[0054] During maintenance, loosen the locking nut 83 to allow sufficient space for rotation, then rotate the threaded rod 81 so that it disengages from the through hole 821, at which point the rotating cover 7 can be opened.

[0055] Preferably, by Figure 1 As shown, this embodiment further includes: a first connecting flange 11 and a second connecting flange 31. The first connecting flange 11 is fixed to the top of the fixed box 1, and the second connecting flange 31 is fixed to the bottom of the guide shroud 3 and is adapted to the first connecting flange 11. With the above scheme, when in use, the guide shroud 3 and the fixed box 1 are assembled using the first connecting flange 11 and the second connecting flange 31. The modular design can effectively reduce maintenance costs and allows for individual repair or replacement of damaged parts.

[0056] Components not described in detail in this article are existing technologies.

[0057] The working principle and usage process of this utility model: When the cooling water falls from the upper spray system of the cooling tower, it first enters the guiding area of ​​the guide shroud 3. The high-speed falling water impacts the surface of the guide plate 5. Since the guide plate 5 is elastically connected to the guide shroud 3 through the buffer component 6, the impact force of the water will drive the guide plate 5 to move downward along the guide column 62, compressing the telescopic spring 63 sleeved on the guide column 62. In this process, the telescopic spring 63 absorbs the impact energy of the water flow through elastic deformation, converting kinetic energy into elastic potential energy, effectively reducing the rigid impact of the water flow on the guide plate 5, thereby reducing the splashing phenomenon caused by the impact.

[0058] When the dispersed water flow passes through the evenly distributed guide holes 51 on the guide plate 5, it is divided into multiple fine streams, thus achieving initial water distribution;

[0059] The equally spaced design of the guide holes 51 ensures that the water flow is evenly distributed on the cross-section, avoiding local water concentration. As the guide plate 5 moves downward due to the impact of the water flow, the compression reaction force of the telescopic spring 63 gradually increases. When the impact force of the water flow and the spring force reach a dynamic balance, the guide plate 5 stops moving downward and maintains a stable buffer state. At this time, the guide holes 51 and the water inlet surface of the packing body 2 form the optimal guide angle, so that the water flow falls vertically into the heat dissipation area of ​​the packing body 2 at a steady speed.

[0060] When the spray water volume changes, the adaptive characteristics of the buffer assembly 6 come into play: if the water volume increases, resulting in a stronger impact force, the guide plate 5 will further compress the telescopic spring 63 to absorb more impact energy by increasing the buffer stroke; if the water volume decreases, the elastic restoring force of the telescopic spring 63 will push the guide plate 5 to return to its original position along the guide post 62.

[0061] Throughout the entire operation, the guide shroud 3 plays a preliminary role in converging the water flow, the buffer component 6 attenuates the impact energy of the water flow through an elastic buffering mechanism, and the guide plate 5, together with the guide hole 51, achieves uniform water distribution. The three work together to ensure that the cooling water enters the packing body 2 in a stable and uniform state. The packing body 2 further disperses the water flow into a water film or water droplets, increasing the contact area with air and improving the heat exchange efficiency. At the same time, because the impact energy is effectively absorbed, the splashing phenomenon of the water flow when entering the packing is significantly suppressed, reducing the loss of cooling water and improving the overall performance of the cooling tower.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
