Description

Technical Field

[0001] This utility model relates to a cooling tower water collection tray with partitioned sedimentation. Background Technology

[0002] Cooling towers, as crucial components of industrial circulating cooling water systems, are widely used in power, chemical, and metallurgical industries. During operation, the circulating water, cooled by heat exchange, collects in a water collection basin at the bottom of the tower and is then transported to the water-using equipment via the outlet system. The water collection basin, being a key component of the cooling tower, directly impacts the operational efficiency and stability of the entire cooling system.

[0003] Currently, the bottom plate area of ​​traditional water collection trays mostly adopts a flat plate structure or a simple segmented splicing form. During long-term operation, silt, scale, impurities and other substances carried by the circulating water will accumulate at the bottom of the water collection tray. These sediments can easily enter the outlet directly with the water flow, thereby clogging the nozzles and pipes of the water distribution system, resulting in a decrease in the heat exchange efficiency of the cooling tower and an increase in equipment maintenance costs.

[0004] After searching the existing technology, Chinese patent CN216645052U was found to disclose a cooling tower water collection tray with partitioned sedimentation. This tray uses a base plate and connecting strips for interlocking. The connecting strips, in a cross-shaped structure, divide the base plate into multiple areas, improving leak-proof performance. However, in this technical solution, the base plates are only separated by planar partitions, and there is no height difference between the different base plate areas. This fails to effectively block sediment impurities in the circulating water. The sediment still flows freely with the water and enters the outlet, failing to achieve a filtration function. Consequently, the problems of water distribution system blockage and reduced heat exchange efficiency persist. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a cooling tower water collection tray with partitioned sedimentation, which can block impurities from directly entering the water outlet system, prevent blockage and improve the heat exchange efficiency of the cooling tower.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cooling tower water collection tray with partitioned sedimentation, comprising:

[0007] The water collection tray body includes a base plate structure and a flange arranged around the outermost periphery of the base plate structure;

[0008] The surface of the base plate structure is provided with multiple horizontally extending and upwardly protruding water-proof barriers, which divide the base plate structure into multiple base plate areas.

[0009] The base plate structure is provided with at least one water outlet, which is located near the flange, and the water-proof sill is provided between the base plate area where the water outlet is located and the adjacent base plate area.

[0010] Furthermore, the base plate structure includes multiple detachably connected base plate units, the edges of adjacent base plate units are folded upwards to form folded edges, and the relative folded edges of adjacent base plate units are adapted to be fixedly connected by bolts, the folded edges forming the water-proof sill.

[0011] Furthermore, in order to improve the sealing performance of the folded edges between adjacent base plate units, a sealing strip is provided between the folded edges of adjacent base plate units.

[0012] Furthermore, the base plate structure is a single base plate, and the single base plate is provided with multiple integrally formed upward protruding partitions. The multiple partitions are arranged in a cross pattern to divide the single base plate into multiple base plate areas, and the partitions form the water-proof sill.

[0013] Furthermore, the base plate structure is a single base plate, and the single base plate is provided with multiple detachable and installable partitions. The inner side of the flange is provided with a connecting structure suitable for connecting the partitions. The multiple partitions are combined to divide the single base plate into multiple base plate areas, and the partitions form the water-proof sill.

[0014] Furthermore, in order to better connect the joints of adjacent partitions, the cooling tower water collection tray with partitioned sedimentation also includes a cross connector, which is disposed at the joint of adjacent partitions and is suitable for fixing the adjacent partitions.

[0015] Furthermore, multiple mounting holes are provided around the water outlet.

[0016] The cooling tower water collection tray with partitioned sedimentation also includes a cover plate adapted to be connected to the mounting hole by bolts to close the water outlet.

[0017] Furthermore, a drain outlet is provided at the bottom of the flange.

[0018] Furthermore, the bottom surface of the base plate structure is provided with flow-blocking patterns.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects:

[0020] In this invention, cooling water is poured from above the cooling tower into the water collection tray. As the water flows across the surface of the base plate structure, it encounters multiple horizontally extending and upwardly protruding water barriers. Because the water barriers divide the base plate structure into multiple base plate areas, the flow velocity decreases when the water flows across the water barriers. Impurities, scale, and other particles carried in the water settle in each base plate area due to gravity. When the water flows to the outlet near the flange, the water barriers between the base plate area where the outlet is located and the adjacent base plate area prevent the impurities and scale that have settled in the previous base plate area from entering the base plate area where the outlet is located. This significantly reduces the impurity content in the water entering the outlet, solving the technical problem of impurities and scale in the cooling water entering the circulation system, causing blockage of the water distribution system and a decrease in heat exchange efficiency. This achieves the technical effect of completing the initial purification of water quality in the water collection tray and reducing the frequency of maintenance of the circulation system.

[0021] The bottom surface of the base plate structure is provided with flow-blocking patterns to increase water flow resistance and increase bottom surface friction, making it difficult for settled impurities to be carried by the water flow.

[0022] In summary, this utility model divides the base plate into multiple base plate areas by setting multiple water-blocking barriers on the surface of the base plate structure. The water-blocking barriers block the water flow, allowing impurities to settle. By setting a water-blocking barrier in front of the base plate area where the water outlet is located, the settled impurities are prevented from entering the circulation system. This solves the problem of blockage in the water distribution system caused by impurities in the cooling water, reduces the maintenance cost of the circulation system, and extends the service life of the equipment.

[0028] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] Example 1: As Figure 1 As shown, a cooling tower water collection tray with zoned sedimentation includes:

[0030] The water collection tray body includes a base plate structure 1 and a flange 2 arranged around the outermost periphery of the base plate structure 1.

[0031] The surface of the base plate structure 1 is provided with multiple horizontally extending and upwardly protruding water-proof barriers 3, which divide the base plate structure 1 into multiple base plate areas.

[0032] The base plate structure 1 is provided with a water outlet 4, which is located near the flange 2. A water-proof sill 3 is provided between the base plate area where the water outlet 4 is located and the adjacent base plate area.

[0033] In this embodiment, as Figure 1 As shown, cooling water is poured from above the cooling tower into the water collection tray. During the flow of water on the surface of the base plate structure 1, it encounters multiple horizontally extending and upwardly protruding water-proof barriers 3. Since the water-proof barriers 3 divide the base plate structure 1 into multiple base plate areas, the flow velocity of the water decreases when crossing the water-proof barriers 3. Impurities, scale, and other particles carried in the water settle in each base plate area due to gravity. When the water flows to the outlet 4 near the flange 2, the water-proof barriers 3 between the base plate area where the outlet 4 is located and the adjacent base plate area prevent the impurities and scale that have settled in the previous base plate area from entering the base plate area where the outlet 4 is located. This significantly reduces the impurity content in the water entering the outlet 4, solving the technical problem of impurities and scale in the cooling water entering the circulation system, causing blockage of the water distribution system and a decrease in heat exchange efficiency. It achieves the technical effect of completing the initial purification of water quality in the water collection tray and reducing the frequency of maintenance of the circulation system.

[0034] Example 2 is basically the same as Example 1, except that:

[0035] Specifically, such as Figure 1 As shown, the base plate structure 1 includes multiple detachably connected base plate units. The edges of adjacent base plate units are folded upwards to form folded edges. The relative folded edges of adjacent base plate units are suitable for fixed connection by bolts 5, and the folded edges form a water-proof sill 3.

[0036] Specifically, such as Figure 1 As shown, a sealing strip is provided between the folded edges of adjacent base plate units.

[0037] In this embodiment, as Figure 1-2As shown, the base plate unit is formed by stamping steel plate with a thickness of 2mm~4mm, specifically 3mm. The edge of each base plate unit is folded upward to form a folded edge with a height of 30mm. Adjacent base plate units are connected by M10 bolts 5 through their respective folded edges. The bolt spacing of bolts 5 is 150mm and the edge distance is 50mm. The folded edge protrudes upward to form a water-blocking barrier 3. When the water flow crosses the water-blocking barrier 3 formed by the folded edge, the flow velocity decreases and impurities in the water settle in the base plate area before the folded edge.

[0038] The sealing strip is made of rubber and is placed between the folded edges of adjacent base plate units. The sealing strip is compressed and fills the gap between the folded edges during the tightening of bolt 5 to prevent water from leaking from the connection of the base plate units.

[0039] The number of base plate units is fifteen, arranged in a 3×5 rectangular array. In some embodiments, the number of base plate units can be set according to the overall size of the water collection tray.

[0040] Specifically, such as Figure 3 As shown, the cooling tower water collection tray with partitioned sedimentation also includes a cross connector 9, which is disposed at the connection of adjacent partitions 7 and is suitable for fixing adjacent partitions 7.

[0041] In this embodiment, as Figure 1-2 As shown, the cross connector 9 is a metal connector. The cross connector 9 is set at the connection of adjacent partitions 7. The four branches of the cross connector 9 are respectively connected to the ends of the adjacent partitions 7 by bolts 5. The cross connector 9 fixes the adjacent partitions 7 to form a grid structure. The partitions 7 remain in the same position under the impact of water flow.

[0042] Example 3 is basically the same as Example 1, except that:

[0043] Specifically, such as Figure 2 As shown, the base plate structure 1 is a single base plate 6. Multiple integrally formed upward-protruding partitions 7 are provided on the single base plate 6. The multiple partitions 7 are arranged in a cross pattern to divide the single base plate 6 into multiple base plate areas. The partitions 7 form a water-proof sill 3.

[0044] In this embodiment, as Figure 2 As shown, a single base plate 6 is formed with multiple upward-protruding partitions 7 on its surface through a stamping process. The partitions 7 are arranged in a cross shape to divide the single base plate 6 into multiple base plate areas. The height of the partitions 7 is 30mm. The partitions 7 form a water-blocking sill 3 to block impurities in the water flow. When the water flows through the partitions 7, the flow velocity decreases, causing impurities to settle in each base plate area. The one-piece molding structure of the single base plate 6 eliminates the connection gaps between base plate units.

[0045] Example 4 is basically the same as Example 1, except that:

[0046] Specifically, such as Figure 4 As shown, the base plate structure 1 is a single base plate 6. Multiple detachable partitions 7 are provided on the single base plate 6. The inner side of the flange 2 is provided with a connecting structure 8 suitable for connecting the partitions 7. The multiple partitions 7 are combined to divide the single base plate 6 into multiple base plate areas, and the partitions 7 form a water-proof sill 3.

[0047] In this embodiment, as Figure 4 As shown, the partition 7 is made of steel plate. The end of the partition 7 is provided with a plug-in structure. The inner side of the flange 2 is provided with a connecting groove that cooperates with the plug-in structure. The partition 7 is fixed by inserting the plug-in structure into the connecting groove. Multiple partitions 7 are combined to divide a single bottom plate 6 into multiple bottom plate areas. The partitions 7 form a water-blocking sill 3. The partitions 7 can be disassembled and installed to facilitate the adjustment of the number and size of the bottom plate areas according to different flow requirements. In some embodiments, the partitions 7 can also be arranged in a cross pattern.

[0048] Specifically, such as Figure 5 As shown, a drain outlet 11 is provided at the bottom of the flange 2.

[0049] Specifically, such as Figure 5 As shown, the bottom surface of the base plate structure 1 is provided with flow-blocking patterns 12.

[0050] In this embodiment, as Figure 5 As shown, the drain outlet 11 is located at the lowest point of the base plate near the flange 2. The drain outlet 11 is connected to an external discharge system via a connecting pipe, which is equipped with a valve for controlling its opening and closing. During normal operation, the valve remains closed to ensure the sealing of the base plate area. When a drain operation is required, the outlet 4 is first temporarily covered with a cover plate; a complete seal is not necessary, only to prevent larger impurities or sediment from entering the outlet 4. Then, the partition plate 7, which forms a water-blocking sill, is removed, creating a connected discharge area for each base plate area. Afterward, the valve is opened and the base plate area is cleaned. Impurities and sludge deposited by gravity in the base plate area are discharged through the drain outlet 11 to the external collection device under the action of liquid flow. After draining, the valve is closed and the partition plate 7 is reset, allowing the base plate area to reform its partition structure, thus restoring the device to its normal operating state.

[0051] For cleaning operations in other embodiments, manual scraping, spraying with a flushing device, or external flushing pipelines can be selected according to the site conditions to clean the deposits in the bottom plate area.

[0052] The drain outlet 11 is located at the bottom of the flange 2. A valve is installed on the pipe connected to the drain outlet 11. The valve is normally kept closed. When sewage needs to be discharged, the partition 7 is removed and the valve is opened. The impurities and sludge deposited in the bottom plate area are discharged through the drain outlet 11.

[0053] The flow-blocking pattern 12 is a striped pattern structure. The flow-blocking pattern 12 is set on the bottom surface of the bottom plate structure 1. The flow-blocking pattern 12 increases the resistance of water flow on the bottom surface. The water flow speed is reduced, which makes the sedimentation speed of impurities faster. At the same time, the flow-blocking pattern 12 increases the friction of the bottom surface, making it difficult for the settled impurities to be carried by the water flow. In some embodiments, the flow-blocking pattern 12 can also be a grid pattern or a raised dot pattern.

[0054] In addition, this embodiment also includes the cross connector 9 as in Embodiment 2. In this embodiment, the cross connector 9 is disposed at the connection of adjacent partitions 7, and is suitable for fixing the partitions 7 that are arranged in a grid (or lattice) pattern.

[0055] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. 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.
