Description

Technical Field

[0001] This utility model belongs to the field of air cooler technology, specifically relating to an antifreeze and cleaning device and an air cooler equipment for air coolers. Background Technology

[0002] In water-scarce regions, such as Northwest and North my country, which are rich in coal but lack water, the adoption of direct air cooling technology has become an inevitable trend. Air coolers use ambient air as the cooling medium. Compared to traditional industrial cooling systems that use water, direct air cooling technology is widely used due to its advantages such as not consuming large amounts of water, ease of operation, lower investment, no environmental pollution, resistance to atmospheric corrosion, and high heat transfer efficiency.

[0003] The methanol-to-olefins production unit of a 680,000-ton coal-to-olefins project in Xinjiang is located in Urumqi, a water-scarce region with an annual temperature ranging from -32.9 to 43.7°C. The prevailing winds throughout the year are westerly and northerly, with northwesterly winds in summer. Therefore, air coolers are the preferred choice for cooling equipment.

[0004] An air cooler consists of a frame, fan, tube bundle fins, louvers, heating tubes, and auxiliary platforms and ladders. Among these, the tube bundle fins and fan are the core components of the air cooler, determining its heat exchange capacity.

[0005] Before winter, the lowest layer of steam heating tubes of the air cooler were put into operation, and the top louvers were completely closed. However, since the louvers could not completely seal the fan outlet, the bottom few rows of finned tubes were constantly exposed to cold air. In the early stages of operation, the air cooler frequently experienced finned tube freezing and cracking, leakage, and bulging of the tube box due to freezing. During unplanned emergency repairs, the number of air coolers in use was reduced, causing changes in the quench water temperature and affecting the balance of various aspects of the water system.

[0006] Therefore, designing an antifreeze and cleaning device for air coolers is beneficial to solving the problem of air coolers being prone to freezing and blockage. Utility Model Content

[0007] To address some or all of the aforementioned technical problems in the existing technology, this utility model proposes an antifreeze and cleaning device and an air cooler device. This antifreeze and cleaning device for air coolers can create a mixed air circulation mode above the air cooler through a baffle, effectively solving the problems of easy freezing and blockage, and difficulties in antifreeze and anti-condensation of air coolers in high-altitude and cold regions.

[0008] According to one aspect of this utility model, an antifreeze and cleaning device for an air cooler is provided, comprising:

[0009] Two guide rails with relatively alternating spacing,

[0010] A baffle is installed between the two guide rails. The baffle is constructed as a split structure in the length direction and includes at least a support section connected to the guide rails, a connecting section hinged to the support section, and a flow guide section hinged to the connecting section.

[0011] A support rod is installed between the support section and the guide section.

[0012] In one embodiment, the support rod is constructed as a telescopic rod, with first connectors fixed at both ends of the telescopic rod, and second connectors fixed on the support section and the guide section, respectively. Each of the first connectors is matched and detachably connected to the corresponding second connector.

[0013] In one embodiment, a plurality of second connectors spaced apart along the length direction of the baffle are provided on at least one of the support section and the guide section, and the first connectors are selectively provided on the second connectors.

[0014] In one embodiment, the first connector is configured as a U-shaped retaining ring with a first connecting hole, and the second connector has a second connecting hole. A connecting bolt passes through the first connecting hole and the second connecting hole to connect the first connector and the second connector.

[0015] In one embodiment, the telescopic rod comprises at least two rod sections connected by a thread.

[0016] In one embodiment, a plurality of nozzles are detachably provided on the inner side of the baffle, and the nozzles are connected to an external cleaning liquid source via hoses.

[0017] In one embodiment, a control valve assembly is provided on the hose to control the amount and pressure of the cleaning fluid.

[0018] In one embodiment, the baffle is movably connected to the guide rail along its length.

[0019] In one embodiment, a roller is provided on the baffle plate, the roller being used to drive the baffle plate to move relative to the guide rail, and a brake is provided on the roller.

[0020] According to another aspect of the present invention, an air cooler device is provided, comprising:

[0021] air cooler,

[0022] The aforementioned antifreeze and cleaning device for an air cooler is provided on the top of the air cooler. The guide rails are fixed on both sides of the louvers of the air cooler, and the axial direction of the guide rails is parallel to the length direction of the tube bundle fins of the air cooler.

[0032] To make the technical solution and advantages of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0033] An embodiment of this utility model provides an antifreeze and cleaning device for air coolers. For example... Figure 1 and 2 As shown, the antifreeze and cleaning device for the air cooler includes guide rails 8, baffles, and support rods 15. There are two guide rails 8, spaced apart and facing each other. After installation, the guide rails 8 are positioned on both sides of the louvers 24 of the air cooler 1. The guide rails 8 primarily serve as basic support and guide the movement of the baffles. The baffles are mounted between the two guide rails 8. Structurally, the baffles are constructed as separate units along their length and include at least a support section 10 connected to the guide rails 8, a connecting section 12 hinged to the support section 10, and a guide section 13 hinged to the connecting section 12. The baffles primarily function as a shield to block wind and create circulating air. The support rods 15 are positioned between the support section 10 and the guide section 13 to provide support and define the position between the support section 10 and the guide section 13.

[0034] During use, the antifreeze and cleaning device 100 for the air cooler is installed at the top of the air cooler 1. In cold weather, the variable frequency fan 3 below the air cooler 1 blows air upwards, while the fixed frequency fan 4 below the air cooler 1 draws air downwards. A baffle is installed at the top of the air cooler 1 to receive and change the direction of the airflow, thereby creating a cooling effect within the air cooler equipment. Figure 2 The mixed air circulation mode indicated by the arrow can provide heat to the tube bundle fins 5, which helps to improve the heat balance in various places, avoid the tube bundle fins 5 from solidification, blockage, freezing, cracking, heat exchange efficiency reduction or even failure, and ensure the normal operation of the air cooler.

[0035] For example, in the baffle, the support section 10 and the connecting section 12 are connected by a universal joint 11. Simultaneously, the connecting section 12 and the guide section 13 are also connected by a universal joint 11. Therefore, the support section 10 and the connecting baffle 12, as well as the connecting section 12 and the guide section 13, can all rotate 360° to open and close. This design facilitates baffle storage and angle adjustment of each section.

[0036] In one embodiment, such as Figure 3 As shown, the support rod 15 is constructed as a telescopic rod. Specifically, the telescopic rod includes at least two rod sections 20 connected by threads. The connecting ends of the two rods 20 are threaded together, allowing the length of the telescopic rod to be adjusted by tightening the threads. It is easy to understand that multiple telescopic rods can be installed on the baffle, spaced apart along the width of the baffle. By installing multiple telescopic rods, the structural strength of the support section 10, connecting section 12, and guide section 13 can be increased.

[0037] First connecting members 21 are fixed at both ends of the telescopic rod. Simultaneously, second connecting members 14 are fixed on the support section 10 and the guide section 13, respectively. Each first connecting member 21 is matched and detachably connected to the corresponding second connecting member 14. That is, the first connecting member 21 at one end of the telescopic rod is detachably connected to the second connecting member 14 on the support section 10, while the first connecting member 21 at the other end of the telescopic rod is detachably connected to the second connecting member 14 on the guide section 13.

[0038] Preferably, a plurality of second connecting members 14 spaced apart along the length direction of the baffle are provided on at least one of the support section 10 and the guide section 13. Specifically, a plurality of second connecting members 14 are provided on the support section 10. A plurality of second connecting members 14 are also provided on the guide section 13. The first connecting members 21 at both ends of the telescopic rod are selectively provided on the second connecting members 14. It can be seen that this arrangement allows for convenient adjustment of the position of the telescopic rod, thereby adjusting the extension state of the baffle. For example, shortening the length of the telescopic rod can reduce the angle between the support section 10 and the guide section 13, shortening the height and length of the forward extension of the guide section 13. Conversely, lengthening the telescopic rod increases the angle between the support section 10 and the guide section 13, raising and extending the height and length of the forward extension of the guide section 13. By controlling the position of the telescopic rod, and thus the working state of the baffle, it helps to keep the temperature of the "mixing air" basically within a suitable temperature range.

[0039] The first connector 21 is constructed as a U-shaped retaining ring. A first connecting hole 25 is provided on the U-shaped retaining ring. The second connector 14 is provided with a second connecting hole 26. It is easy to understand that the second connector 14 can be a perforated sheet or block, or even a ring. The connecting bolt 22 passes through the first connecting hole 25 and the second connecting hole 26 to connect the first connector 21 and the second connector 14. This simple design achieves a detachable connection between the first connector 21 and the second connector 14, facilitating the replacement of the telescopic rod's position on the baffle.

[0040] According to this application, a nozzle 16 is detachably installed on the inner side of the baffle. The nozzle 16 is connected to an external cleaning liquid source 18 via a hose 17. For example, the external cleaning liquid source is high-pressure softened water. During use, high-pressure softened water can be delivered to the nozzle 16 through the hose 17, and then sprayed out through the nozzle 16 to periodically clean the accumulated dust and lint on the tube bundle fins 5, ensuring that the air cooler has a large air-cooling area and a high heat transfer coefficient. Multiple nozzles 16 can be installed and connected via branched hoses 17 to increase the cleaning range. Figure 4 As shown, the nozzle 16 itself can be constructed as a generally frustum structure, with the diameter of the spraying end being smaller than the diameter of the fixed end. Additionally, each nozzle 16 can have multiple nozzles capable of spraying cleaning fluid in different directions to improve the cleaning effect.

[0041] Preferably, a control valve assembly 19 is provided on the hose 17 to control the flow rate and pressure of the cleaning fluid, achieving precise cleaning and ensuring cleaning effectiveness. Both the nozzle 16 and the hose 17 can be freely disassembled and installed. When cleaning is not used for extended periods, the nozzle 16 and hose 17 can be disassembled for maintenance. For example, the nozzle 16 and hose 17 can be disassembled for maintenance in winter and then reinstalled according to operating conditions after the weather warms up.

[0042] Along the length of the guide rail 8, the baffle is movably connected to the guide rail 8. For example, rollers 9 are provided at the bottom corners of both sides of the support section 10 of the baffle. These rollers 9 are used to drive the baffle to reciprocate linearly on the track 8. Specifically, as shown... Figure 5 and 6 As shown, two rollers 9 are rotatably arranged on each side of the support section 10 of the baffle. These two rollers 9 are arranged vertically to clamp the guide rail 8. During the cleaning process, the baffle is pushed to slide back and forth on the guide rail 8, which can repeatedly rinse the tube bundle fins 5 of the air cooler 1 from all directions to ensure the cleaning effect.

[0043] Specifically, as shown in Figures 6 and 7, a brake 23 is provided on at least one of the upper rollers 9 to fix the baffle at any horizontal position on the guide rail 8. Anti-slip plates 7 are provided at both ends of each guide rail 8 to prevent the rollers 9 from slipping off the ends of the guide rail 8.

[0044] This application also relates to air cooler equipment. The air cooler equipment includes an air cooler 1 and the aforementioned antifreeze and cleaning device for the air cooler. The air cooler 1 can be an air cooler in the prior art, for example, the air cooler includes an air cooler steel structure 2 that provides main support, a variable frequency fan 3 installed below the air cooler steel structure 2, a power frequency fan 4 installed below the air cooler steel structure 2, tube bundle fins 5 installed above the air cooler steel structure 2, and tube box plugs 6 installed at both ends of the length of the tube bundle fins, etc. The antifreeze and cleaning device for the air cooler according to this application is installed on the top of the air cooler 1. After installation, guide rails 8 are fixed to both sides of the louvers 24 of the air cooler, and the axial direction of the guide rails 8 is parallel to the length direction of the tube bundle fins 5 of the air cooler. A baffle at least partially covers the top of the air cooler 1.

[0045] This air cooler can meet the operating conditions of air cooler 1 in different seasonal environments. For example, in spring and summer, the dust and lint on the tube bundle fins 5 can be cleaned regularly by the cleaning components such as nozzle 16, so as to ensure that the air cooler has a large air cooling area and a high heat transfer coefficient. In winter, when the air cooler is in anti-freezing mode, the fixed frequency fan 4 can be adjusted to induced draft mode, while the variable frequency fan 3 remains in forced draft mode. The anti-freezing and cleaning device for the air cooler is fixed directly above the outlet of the variable frequency fan 3. When the louvers 24 are open, the air above the louvers 24 passes through the tube bundle fins 5 and is heated into "hot air" and led to the bottom of the fixed frequency fan 4. The variable frequency fan 3 rotates and generates an upward vortex, forming a low-pressure area below the variable frequency fan 3. The "hot air" led to the bottom by the fixed frequency fan 4 is drawn into the inlet of the variable frequency fan 3. The upward air drawn into the variable frequency fan 3 exchanges heat with the tube bundle fins 5 and is heated into "hot air" again. This "hot air" encounters the anti-freezing and cleaning device for the air cooler and changes from vertical to horizontal flow under the action of the baffle. The horizontally flowing "hot air" is then drawn into the low-pressure inlet of the fixed frequency fan 4, forming a hot air circulation. By controlling the working angle of the baffle with the telescopic rod, the amount of hot circulating air flowing to the inlet of the industrial frequency fan can be adjusted. Furthermore, changing the operating power of the variable frequency fan 3 can also adjust the circulation volume of "hot air" and the intake volume of "cold air," keeping the temperature of the "mixed air" in the suction tube bundle fins 5 within a suitable range. It is evident that this "mixed air" circulation mode created for winter effectively solves the problems of easy freezing and blockage, and difficulties in antifreeze and anti-condensation in air coolers in high-altitude and cold regions. This antifreeze and cleaning device for air coolers has a reasonable overall structural design, is easy to operate, runs stably, and has good adjustment performance. Its use expands the application range of air coolers, effectively avoids resource waste, reduces secondary environmental pollution, and has certain economic and social benefits. It is recommended to promote its use in suitable areas.
