Description

Technical Field

[0001] This application relates to the field of air cooler technology, and more particularly to an air cooler and cooling system. Background Technology

[0002] In polysilicon production, the purification of chlorosilane mixtures mainly relies on distillation columns. The gaseous products separated from the distillation columns are cooled by air coolers before entering the next process. An air cooler is a heat exchanger that uses air to cool hot fluids.

[0003] Currently, the air cooler includes a support frame, heat exchange tubes and a fan mounted on the frame, with the fan outlet facing the heat exchange tubes. As the material flows through the heat exchange tubes, it exchanges heat with the air blown out by the fan, thus cooling the material.

[0004] However, high summer temperatures reduce the cooling efficiency of air coolers, causing the gaseous products from the distillation process to fail to meet cooling requirements and thus be unusable in the next process. Instead, they are discharged through the exhaust pipeline, resulting in product waste. Utility Model Content

[0010] The spray assembly includes a spray pipe and multiple nozzles installed on the spray pipe. The nozzles extend between two adjacent heat exchange tubes, and nozzles are respectively provided on opposite sides of the nozzles. The nozzles on both sides of the nozzles are used to spray cooling water onto the heat exchange tubes on both sides.

[0013] In one possible implementation, the nozzle further includes a third connecting section, one end of which is connected to the second connecting section, and the other end of which forms a flat nozzle, the length direction of which is parallel to the extension direction of the heat exchange tube.

[0014] In one possible implementation, multiple heat exchange tubes are arranged in multiple layers, with each layer containing multiple heat exchange tubes.

[0015] The second connecting section is provided with multiple nozzle groups, which are arranged at intervals along the axial direction of the second connecting section. The height of the multiple nozzle groups corresponds one-to-one with the height of the multi-layer heat exchange tubes. Each nozzle group includes two nozzles located on opposite sides of the second connecting section.

[0016] In one possible implementation, the spray pipe includes a main pipe and multiple parallel branch pipes spaced apart. One end of each branch pipe is connected to the main pipe, and the extension direction of the branch pipe is perpendicular to the extension direction of the heat exchange tube. Multiple nozzles are installed on each branch pipe at intervals.

[0017] In one possible implementation, a laterally extending support beam is provided on the bracket, with the end of the branch pipe away from the main pipe placed on the support beam.

[0018] In one possible implementation, the drainage assembly includes a water receiving tray and a drain pipe. The water receiving tray is positioned below the spray assembly to collect cooling water dripping from the heat exchange tubes, and one end of the drain pipe is connected to the bottom of the water receiving tray.

[0019] In one possible implementation, the drainage assembly also includes multiple support legs disposed at the bottom of the water receiving tray, which is positioned below the spray assembly via the multiple support legs.

[0020] In one possible implementation, the cross-sectional area of ​​the water receiving tray gradually decreases from top to bottom.

[0021] Secondly, this application provides a cooling system including a water storage tank, a water pump, a first connecting pipe, a second connecting pipe, and the aforementioned air cooler. The two ends of the first connecting pipe are respectively connected to the spray pipes of the water storage tank and the air cooler, and the two ends of the second connecting pipe are respectively connected to the water storage tank and the drain assembly of the air cooler. The water pump is mounted on the first connecting pipe.

[0022] The air cooler and cooling system provided in this application include a support frame, heat exchange tubes, a fan, a spray assembly, and a water drainage assembly. The fan and spray assembly are respectively mounted on the support frame, and the fan cools the material in the heat exchange tubes. The spray assembly includes a spray pipe and multiple nozzles mounted on the spray pipe.

In this way, by spraying cooling water onto the heat exchange tubes through the spray assembly, the cooling efficiency of the material in the heat exchange tubes is increased, ensuring that the gaseous products in the distillation process meet the cooling requirements.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0047] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0048] In existing technologies, such as Figure 1 As shown, the air cooler 10 includes a support 100 and heat exchange tubes 200 and a fan 300 respectively mounted on the support 100. The air outlet of the fan 300 faces the heat exchange tubes 200. When the material flows in the heat exchange tubes 200, it exchanges heat with the air blown out by the fan 300 to achieve cooling. However, the cooling effect of the air cooler 10 is significantly affected by the external environment. In actual production, high temperatures in summer will reduce the cooling efficiency of the air cooler 10. During the distillation process, when the distillation column is overloaded, the vapor product at the top of the column will exceed the capacity and temperature. When cooled by the air cooler 10, it will exceed the load of the air cooler 10. The vapor product cannot be cooled down and cannot be sent to the next process. It can only be discharged through the tail gas pipeline, resulting in product waste.

[0049] In polysilicon production, air coolers or water coolers are usually added when the cooling capacity is insufficient. However, in actual production, there is not such a large difference in cooling capacity. Directly adding air coolers or water coolers will lead to high costs, long purchase and installation cycles, and the problem of equipment being idle when the tower is running normally or in winter, as the cooling capacity of the air cooler is sufficient.

[0050] After repeated consideration and verification, the inventors discovered that by installing a spray assembly in the air cooler, the nozzles of the spray assembly can extend between two adjacent heat exchange tubes, and the nozzles can spray cooling water onto the heat exchange tubes on both sides. This increases the cooling efficiency of the material in the heat exchange tubes on both sides of the nozzle, allowing the gaseous products in the distillation process to meet the cooling requirements. Furthermore, by installing a water collection assembly in the air cooler, the cooling water dripping from the heat exchange tubes can be collected and reused, reducing waste and lowering the cooling cost of the gaseous products separated from the distillation column.

[0051] In view of this, the inventors designed an air cooler and cooling system that sprays cooling water onto the heat exchange tubes via a spray assembly, increasing the cooling efficiency of the material within the tubes. The nozzles of the spray assembly can extend between adjacent heat exchange tubes to spray cooling water onto both sides, ensuring effective spraying while reducing the number of nozzles required. A drainage assembly collects the cooling water dripping from the heat exchange tubes, minimizing waste.

[0052] The technical solutions of the air cooler and cooling system provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0053] Reference Figures 2 to 4 As shown in the embodiment of this application, the air cooler 10 includes a bracket 100, heat exchange tubes 200, a fan 300, a spray assembly, and a drainage assembly 500. There are multiple heat exchange tubes 200, all mounted on the bracket 100, and the heat exchange tubes 200 are configured to carry fluid materials. Indicatively, the heat exchange tubes 200 can be installed near the top of the bracket 100, and each heat exchange tube 200 can extend laterally.

[0054] The fan 300 is mounted on the top of the bracket 100, with its air outlet facing the heat exchange tube 200. The fan 300 is located above the heat exchange tube 200, and its air outlet is located below the fan 300. The fan 300 can blow air downwards, driving air through the heat exchange tube 200 to remove the heat from the material in the heat exchange tube 200, thereby cooling the material.

[0055] The spray assembly includes a spray pipe 410 and a plurality of nozzles 420 installed on the spray pipe 410. The nozzles 420 extend between two adjacent heat exchange tubes 200. Nozzles 4231 are respectively provided on opposite sides of the nozzles 420. The nozzles 4231 on both sides of the nozzles 420 are used to spray cooling water onto the heat exchange tubes 200 on both sides.

[0056] The number of nozzles 420 is not limited and can be set by those skilled in the art according to actual needs. The temperature of the cooling water can be set as needed, for example, the temperature of the cooling water can be 7℃-25℃. After the nozzles 420 spray cooling water onto the heat exchange tubes 200, on the one hand, the cooling water can directly exchange heat with the material in the heat exchange tubes 200 to achieve material cooling; on the other hand, some of the cooling water will evaporate on the heat exchange tubes 200 to carry away the heat of the material in the heat exchange tubes 200. In this embodiment, the same nozzle 420 can spray cooling water onto the heat exchange tubes 200 on both sides. Compared with the method of setting one nozzle 420 for each heat exchange tube 200, the number of nozzles 420 can be reduced, and the cost of the air cooler 10 can be reduced.

[0057] The drain assembly 500 is installed below the spray assembly to collect cooling water dripping from the heat exchange tube 200. After the cooling water dripping from the heat exchange tube 200 falls into the drain assembly 500, the cooling water in the drain assembly 500 can be reused, reducing the waste of cooling water.

[0058] The air cooler 10 provided in this embodiment can cool the material in the heat exchange tube 200 through a fan 300. The spray assembly includes a spray pipe 410 and multiple nozzles 420 installed on the spray pipe 410. The nozzles 420 extend between two adjacent heat exchange tubes 200, and nozzles 4231 are respectively provided on opposite sides of the nozzles 420. The nozzles 4231 on both sides of the nozzles 420 are used to spray cooling water onto the heat exchange tubes 200 on both sides. In this way, by spraying cooling water onto the heat exchange tubes 200 through the spray assembly, the cooling efficiency of the material in the heat exchange tubes 200 is increased, so that the gaseous products in the distillation process can meet the cooling requirements. The water discharge assembly 500 can collect the cooling water dripping from the heat exchange tubes 200, reducing the waste of cooling water. In addition, the water discharge assembly 500 can prevent cooling water from splashing onto the ground and causing site chaos.

[0059] In one embodiment, such as Figures 2-5 As shown, the nozzle 420 includes a first connecting section 421 and a second connecting section 422 arranged coaxially. The end of the first connecting section 421 has a tapered section 4211. The second connecting section 422 is connected to the small-diameter end of the tapered section 4211. The nozzle 4231 is disposed on the second connecting section 422.

[0060] For example, the axis of the first connecting segment 421 and the axis of the second connecting segment 422 can extend vertically, and the first connecting segment 421 and the second connecting segment 422 can be fixed by welding. The end of the first connecting segment 421 away from the second connecting segment 422 can be connected to the spray pipe 410, and the end of the second connecting segment 422 away from the first connecting segment 421 is blocked. In one possible implementation, the spray pipe 410 is located below the heat exchange tube 200, and the nozzle 420 can extend from bottom to top between two adjacent heat exchange tubes 200.

[0061] Those skilled in the art will understand that when cooling water flows in the first connecting section 421, the conical section 4211 can compress the flowing cooling water, increasing its flow velocity. That is, the conical section 4211 of the first connecting section 421 ensures the speed at which the cooling water is ejected from the nozzle 4231, guaranteeing that the cooling water reliably falls onto the heat exchange tube 200 after being ejected from the nozzle 4231. Those skilled in the art can set the dimensions of the first connecting section 421, the second connecting section 422, and the conical section 4211 as needed; no single limitation is made here.

[0062] In a specific embodiment, such as Figure 4 and Figure 5 As shown, the nozzle 420 also includes a third connecting section 423. One end of the third connecting section 423 is connected to the second connecting section 422, and the other end of the third connecting section 423 forms a flat nozzle 4231. The length direction of the nozzle 4231 is parallel to the extension direction of the heat exchange tube 200.

[0063] For example, the axial direction of the third connecting section 423 is perpendicular to the axial direction of the second connecting section 422. The size of the third connecting section 423 can be set as needed and is not limited here. The third connecting section 423 can be fixed to the second connecting section 422 by welding. The nozzle 4231 formed at the other end of the third connecting section 423 is flat. When cooling water flows in the third connecting section 423, the third connecting section 423 can squeeze the flowing cooling water, increase the flow velocity of the cooling water, and further ensure that the cooling water can reliably fall onto the heat exchange tube 200 after being sprayed from the nozzle 4231. In addition, the flat nozzle 4231 increases the spray area of ​​the cooling water, so that the cooling water can be sprayed onto the heat exchange tube 200 more evenly.

[0064] It is worth mentioning that the height of the nozzle 4231 is flush with the heat exchange tube 200. Since the length direction of the nozzle 4231 is parallel to the extension direction of the heat exchange tube 200, the contact area between the heat exchange tube 200 and the cooling water is guaranteed, which can further ensure that the cooling water can be sprayed onto the heat exchange tube 200 more evenly.

[0065] like Figures 3-5As shown, multiple heat exchange tubes 200 are arranged in multiple layers, and each layer has multiple heat exchange tubes 200. It is worth mentioning that the projections of two different layers of heat exchange tubes 200 in the vertical direction overlap, so that the nozzle 420 can extend into the space between two adjacent heat exchange tubes 200 in each layer.

[0066] Multiple nozzle groups are provided on the second connecting section 422. The multiple nozzle groups are arranged at intervals along the axial direction of the second connecting section 422. The height of the multiple nozzle groups corresponds one-to-one with the height of the multilayer heat exchange tube 200. Each nozzle group includes two nozzles 4231 located on opposite sides of the second connecting section 422.

[0067] Specifically, the second connecting section 422 of the nozzle 420 extends between two adjacent heat exchange tubes 200 in each layer. The number of nozzle groups is the same as the number of heat exchange tube layers 200. The nozzle 420 sprays coolant into the multi-layer heat exchange tubes 200 through multiple nozzle groups.

[0068] With the above settings, the spray assembly can spray coolant onto each heat exchange tube 200 through the nozzle 420, ensuring the cooling effect of the material in each heat exchange tube 200.

[0069] In one embodiment, such as Figure 2 , Figure 3 and Figure 6 As shown, the spray pipe 410 includes a main pipe 411 and a plurality of parallel and spaced branch pipes 412, one end of each branch pipe 412 being connected to the main pipe 411. The extension direction of the branch pipes 412 is perpendicular to the extension direction of the heat exchange tube 200, and a plurality of spray nozzles 420 are installed at intervals on each branch pipe 412.

[0070] Indicatively, one end of the main pipe 411 can be supplied with cooling water, while the other end is sealed. One end of each branch pipe 412 can be connected to the side wall of the main pipe 411, and each branch pipe 412 can be fixed to the main pipe 411 by welding. The number of branch pipes 412 can be set as needed and is not limited here.

[0071] like Figure 6 As shown, multiple connecting pipes 413 can be installed on the branch pipe 412, and the nozzle 420 can be installed on the connecting pipe 413 by welding or threaded connection.

[0072] It is worth mentioning that multiple nozzles 420 on the same branch pipe 412 can spray cooling water onto different heat exchange tubes 200 respectively, and cooling water can be sprayed onto different positions of the same heat exchange tube 200 along the axial direction by nozzles 420 on different branch pipes 412.

[0073] With the above settings, it can be ensured that cooling water can be sprayed evenly onto different heat exchange tubes 200 and different positions on the same heat exchange tube 200, thereby fully ensuring the cooling effect of the material in the heat exchange tube 200.

[0074] In a specific embodiment, such as Figure 2 and Figure 6 As shown, a laterally extending support beam 110 is provided on the bracket 100, and the end of the branch pipe 412 away from the main pipe 411 is placed on the support beam 110.

[0075] For example, the support beam 110 can be fixed to the main body of the bracket 100 by welding. The main pipe 411 and each branch pipe 412 can be rigid pipes, with one end of the branch pipe 412 supported by the support beam 110 and the other end of the branch pipe 412 supported by the main pipe 411. Optionally, a limiting structure can be provided on the support beam 110, such as a protrusion, to restrict the movement of the branch pipe 412 along the length of the support beam 110. In one possible implementation, a buckle or other fixing structure can be provided on the bracket 100 to fix the main pipe 411.

[0076] With the above configuration, the spray pipe 410 can be reliably placed on the support 100, increasing the stability of the spray assembly and thus reliably improving the cooling efficiency of the material in the heat exchange tube 200.

[0077] In one embodiment, such as Figure 2 , Figure 3 and Figure 7 As shown, the drainage assembly 500 includes a water receiving tray 510 and a drain pipe 520. The water receiving tray 510 is disposed below the spray assembly to collect cooling water dripping from the heat exchange tube 200, and one end of the drain pipe 520 is connected to the bottom of the water receiving tray 510.

[0078] Understandably, the water receiving tray 510 is used to collect cooling water. The specific location and size of the water receiving tray 510 should be sufficient to stably collect the cooling water dripping from the heat exchange tube 200. Schematic, the bottom surface of the water receiving tray 510 has a through hole, and after the bottom of the water receiving tray 510 is connected to the drain pipe 520, the through hole on the bottom surface of the water receiving tray 510 communicates with the drain pipe 520.

[0079] In this structure, the water drain assembly 500 receives cooling water through the water receiving pan 510, and the cooling water in the water receiving pan 510 can be led out through the drain pipe 520, so that the cooling water in the water pan can be reused and reduce the waste of cooling water.

[0080] In a specific embodiment, such as Figure 2 , Figure 3 and Figure 7As shown, the drainage assembly 500 also includes a plurality of support legs 530 disposed at the bottom of the water receiving tray 510, which is placed below the spray assembly via the plurality of support legs 530.

[0081] Each support leg 530 can be fixed to the water receiving tray 510 by fastening with fasteners or welding. For example, as shown... Figure 7 As shown, the cross-sectional shape of the water receiving tray 510 can be rectangular, and the number of support legs 530 can be four, with the four support legs 530 respectively located at the four bottom corners of the water receiving tray 510.

[0082] The support leg 530 ensures the correct height of the water tray 510, preventing a large height difference between the heat exchange tube 200 and the water tray 510, thus reducing splashing of cooling water dripping from the heat exchange tube 200 into the water tray 510. Furthermore, raising the water tray 510 with the support leg 530 provides installation space for the drain pipe 520, preventing the water tray 510 from pressing down on the drain pipe 520.

[0083] In one specific implementation, such as Figure 2 , Figure 3 and Figure 7 As shown, the cross-sectional area of ​​the water receiving tray 510 gradually decreases from top to bottom.

[0084] For example, the side of the water receiving tray 510 can be inclined relative to the bottom surface of the water receiving tray 510, so that the cross-sectional area of ​​the water receiving tray 510 gradually decreases from top to bottom. The above arrangement can improve the water collection efficiency of the water receiving tray 510, which is conducive to the drainage pipe 520 discharging the cooling water in the water receiving tray 510.

[0085] This application also provides a cooling system, including a water storage tank 20, a water pump 30, a first connecting pipe 40, a second connecting pipe 50, and the aforementioned air cooler 10. The two ends of the first connecting pipe 40 are respectively connected to the spray pipes 410 of the water storage tank 20 and the air cooler 10, and the two ends of the second connecting pipe 50 are respectively connected to the water storage tank 20 and the drain assembly 500 of the air cooler 10. The water pump 30 is disposed on the first connecting pipe 40.

[0086] When the sprinkler pipe 410 includes a main pipe 411 and multiple branch pipes 412, the end of the first connecting pipe 40 away from the water storage tank 20 is connected to the main pipe 411. When the drain assembly 500 includes a water receiving tray 510 and a drain pipe 520, the end of the second connecting pipe 50 away from the water storage tank 20 is connected to the drain pipe 520.

[0087] Understandably, the cooling water collected by the drainage assembly 500 can be sent to the water storage tank 20 through the second connecting pipe 50. The cooling water in the water storage tank 20 is then sent to the spray pipe 410 of the air cooler 10 through the first connecting pipe 40 under the action of the water pump 30.

[0088] The cooling system provided in this application, due to the use of the aforementioned air cooler 10, achieves high cooling efficiency for the material in the heat exchange tubes 200, enabling the gaseous products in the distillation process to meet cooling requirements. Furthermore, the cooling system allows for the recycling of cooling water.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
