Description

Technical Field

[0001] This invention relates to the field of air cooler technology, and more specifically to a spray cooling device for air coolers. Background Technology

[0002] An air cooler is a closed-loop indirect contact cooling device widely used in the chemical industry. An axial fan blows air from below the air cooler upwards, where it exchanges heat with the tube bundle, cooling the process medium in the tube bundle. The heat exchange efficiency of the air cooler largely depends on the ambient air temperature.

[0003] When the ambient air temperature is high in summer, the heat exchange effect of air coolers is poor. In order to make the process medium reach the specified temperature, it is often necessary to turn on multiple standby air coolers, which increases the power load and does not significantly improve the heat exchange effect.

[0004] Chinese patent application CN202322917170.3 discloses a spray cooling device for air coolers. Its key technical features include: a main body and a water tank; multiple sets of parallel heat dissipation plates are fixedly installed on the two opposing inner walls of the main body; spray pipes, spaced apart from the heat dissipation plates, are fixedly installed between the inner walls of the main body; a pump is installed on the surface of the water tank, and the pump is connected to the spray pipes via a conduit; a cooling mechanism is installed in the inner cavity of the main body to cooperate with the heat dissipation plates; the cooling mechanism includes a fixing frame, a blower, a circulating humidification section, and a lifting section; the fixing frame has an inverted U-shaped structure, with multiple sets of fixing frames respectively arranged on both sides of the heat dissipation plates; and the fixing frame is slidably connected to the inner wall of the main body in the vertical direction. This solves the problem that existing air coolers have poor heat exchange performance, often requiring the operation of multiple backup air coolers, which increases the power load without significantly improving the heat exchange effect.

[0005] However, when the spray cooling device for air coolers disclosed in the above patent sprays the air cooler to cool it, the air flow direction is always the same. It is impossible to guide the air entering the air cooler cavity in different states according to the ambient temperature, so it is impossible to adjust the cooling time of the air. When the ambient temperature is high, the cooling time of the air through the air cooler cavity remains unchanged, which will result in insignificant air cooling and affect the use effect of the air cooler.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0043] like Figures 1 to 11 As shown, the present invention provides a spray cooling device for an air cooler, comprising: an air cooler body 1; an axial flow fan 3 fixedly installed on the top of the air cooler body 1; a radiator 4 fixedly installed inside the air cooler body 1; and a spray mechanism 2 for spray cooling the air cooler body 1.

[0044] The radiator 4 consists of a heat-conducting plate and a circulation pipe. The circulation pipe is connected to a circulating water tank, so that water can circulate through the circulation pipe. The heat-conducting plate absorbs the heat in the air inside the air cooler body 1 and exchanges heat with the water in the circulation pipe, thereby cooling the inside of the air cooler body 1.

[0045] At the same time, the axial flow fan 3 is started to discharge the cooled air from the air cooler body 1.

[0046] The radiator 4 can be used to initially cool the air inside the air cooler body 1.

[0047] The spray mechanism 2 includes: a water pump 21 fixedly installed on the outside of the air cooler body 1; a water inlet pipe 22 connecting the water inlet end of the water pump 21 to the air cooler body 1; a water outlet pipe 23 connected to the water outlet end of the water pump 21; a diversion pipe 24 connected to the water outlet pipe 23; an atomizing nozzle 25 connected to the diversion pipe 24; and the diversion pipe 24 and the water outlet pipe 23 are rotatably connected.

[0048] Multiple diversion pipes 24 are provided, and each diversion pipe 24 is connected to multiple atomizing nozzles 25, thereby expanding the spraying range of the atomizing nozzles 25.

[0049] A water storage chamber is provided at the bottom of the inner cavity of the air cooler body 1, and the water storage chamber is filled with clean water.

[0050] Since the cooling effect of radiator 4 is limited, the spray mechanism 2 is used to further cool radiator 4, thereby improving the cooling effect on the air inside the air cooler body 1.

[0051] When the water pump 21 is started, the clean water in the water storage chamber is drawn out through the water inlet pipe 22 and transported to the distribution pipe 24 through the water outlet pipe 23. Then, it is atomized and sprayed out through the atomizing nozzle 25. The sprayed water mist adheres to the radiator 4. Through the evaporation and heat absorption of the water mist, the radiator 4 can be cooled down quickly, thereby improving the cooling effect on the air inside the air cooler body 1.

[0052] The spray mechanism 2 further includes: a swing assembly 26 that drives the atomizing nozzle 25 to swing; the swing assembly 26 includes: a first reciprocating screw 262 rotatably installed inside the air cooler body 1; a power source 261 that drives the first reciprocating screw 262 to rotate, the power source 261 being fixedly installed on the outside of the air cooler body 1 by a mounting bracket; a movable plate 263 threadedly connected to the first reciprocating screw 262; a limiting rod 264 that limits the movable plate 263, the limiting rod 264 penetrating the side wall of the movable plate 263, and both ends of the limiting rod 264 being fixedly installed inside the air cooler body 1; a rack 265 fixedly installed at the bottom of the movable plate 263; and a connecting gear 266 fixedly sleeved on the diverter pipe 24; the connecting gear 266 and the rack 265 meshing with each other.

[0053] When the water pump 21 is started, the power source 261 is also started. The power source 261 drives the first reciprocating screw 262 to rotate. The first reciprocating screw 262 drives the moving plate 263 to move. Through the limiting action of the limiting rod 264, the moving plate 263 reciprocates along the axial direction of the first reciprocating screw 262.

[0054] The movable plate 263 drives the rack 265 to move back and forth, and the rack 265 drives the connecting gear 266 to move back and forth, thereby driving the diverter tube 24 to rotate back and forth, and in turn driving the atomizing nozzle 25 to swing back and forth.

[0055] The reciprocating oscillation of the atomizing nozzle 25 can further expand the spraying range of the atomizing nozzle 25, thereby enabling the spraying range of the atomizing nozzle 25 to fully cover the radiator 4, improving the cooling effect on the radiator 4, and further improving the cooling effect on the air inside the air cooler body 1.

[0056] It should be noted that the preferred power source 261 is an electric motor.

[0057] The spray mechanism 2 further includes: a stirring assembly 27 for stirring water; the stirring assembly 27 includes: a cylinder 271 rotatably mounted inside the air cooler body 1; stirring blades 272 fixedly mounted on the cylinder 271, wherein multiple stirring blades 272 are provided and the multiple stirring blades 272 are evenly distributed along the circumference of the cylinder 271; a round rod 273 rotatably mounted on the cylinder 271; and a linkage frame 274 slidably connected to the round rod 273, wherein the linkage frame 274 has a guide groove, the round rod 273 is slidably mounted in the guide groove, a slide bar is fixedly mounted on the linkage frame 274, and a slide groove is provided inside the air cooler body 1. The slide bar is slidably installed in the slide groove; the linkage plate 275 is fixedly connected to the linkage frame 274; the driven bevel gear 277 is coaxially connected to the cylinder 271; the driving bevel gear 276 is meshed with the driven bevel gear 277 and is rotatably installed on the air cooler body 1; the linkage component 278 of the linkage power source 261 and the driving bevel gear 276 is preferably a synchronous pulley or a synchronous belt. There are two synchronous pulleys. One synchronous pulley is fixedly sleeved on the first reciprocating screw 262 and the other synchronous pulley is coaxially connected to the driving bevel gear 276. The two synchronous pulleys are driven by a synchronous belt.

[0058] The water storage chamber is connected to a cold source, which can cool the water in the water storage chamber, thereby ensuring the cooling effect after the water is atomized; the preferred cold source is a refrigeration unit.

[0059] When the power source 261 is started, it can drive the first reciprocating screw 262 to rotate, thereby driving the linkage 278 to run. The linkage 278 drives the driving bevel gear 276 to rotate, the driving bevel gear 276 drives the driven bevel gear 277 to rotate, the driven bevel gear 277 drives the cylinder 271 to rotate, and the cylinder 271 drives the stirring blade 272 to rotate, thereby realizing the circumferential stirring of the water.

[0060] While the cylinder 271 drives the stirring blade 272 to rotate, it can simultaneously drive the rod 273 to rotate. The rod 273 drives the linkage frame 274 to move. The linkage frame 274 drives the slide bar to slide in the adjacent slide groove. Through the limiting effect of the slide bar and the slide groove, the linkage frame 274 moves linearly back and forth under the drive of the rod 273.

[0061] The linkage frame 274 drives the linkage plate 275 to move linearly back and forth, thereby achieving axial stirring of the water.

[0062] By setting the stirring component 27, both circumferential and axial stirring of the water can be achieved, so that the cooling of the water is more uniform and the cooling effect of the water on the radiator 4 is guaranteed.

[0063] The spray mechanism 2 also includes: a flow guiding component 28 for guiding airflow; the flow guiding component 28 includes: a mounting opening on the air cooler body 1, a filter screen 281 fixedly installed in the mounting opening; a mounting frame 282 fixedly installed on the air cooler body 1; a flow guiding plate 283 rotatably installed in the mounting frame 282, the flow guiding plate 283 being rotatably installed in the mounting frame 282 via a rotating shaft, multiple flow guiding plates 283 being provided, and multiple flow guiding plates 283 being driven by a transmission component 285; a second power source 284 for driving the flow guiding plate 283 to rotate, the second power source 284 being fixedly installed on the outside of the mounting frame 282, and the output end of the second power source 284 being fixedly connected to the rotating shaft of any one of the flow guiding plates 283.

[0064] When the air cooler body 1 is not in use, multiple guide plates 283 are arranged vertically, and adjacent guide plates 283 are fitted together. The two guide plates 283 located at the top and bottom are fitted together with the inner wall of the mounting frame 282.

[0065] At this time, multiple baffles 283 can enclose the mounting frame 282, which on the one hand reduces dust adhering to the filter screen 281, thereby reducing the maintenance of the filter screen 281, and on the other hand reduces the evaporation of clean water, avoiding frequent water addition.

[0066] When the axial flow fan 3 is started, the second power source 284 is started to drive the adjacent rotating shaft to rotate, which in turn drives the adjacent guide plate 283 to rotate. Through the setting of the transmission component 285, multiple guide plates 283 can be driven to rotate simultaneously.

[0067] The transmission component 285 is preferably a chain or sprocket, which ensures the synchronous rotation of multiple guide plates 283. A tensioning mechanism can be provided on the chain to ensure that the chain and sprocket are always meshed, thereby further ensuring the synchronous rotation of multiple guide plates 283.

[0068] By setting up filter screen 281, the air entering the air cooler body 1 can be filtered, preventing dust from entering the air cooler body 1 and contaminating the clean water.

[0069] A temperature sensor is installed on the air cooler body 1 to sense the annular temperature and set three threshold ranges, T1, T2, and T3, where T1 is the threshold value. <T2<T3。

[0070] When the ambient air temperature is within the range of T1, there is no need to start the radiator 4 and the spray mechanism 2. Simultaneously, start the axial flow fan 3 and power source 284, thereby driving the guide plate 283 to rotate to the first state, as shown below. Figure 10 As shown.

[0071] At this time, the outside air flows obliquely upward along the guide plate 283, which reduces the time that the air stays in the air cooler body 1 and improves the efficiency of air flow.

[0072] When the ambient air temperature is within the T2 range, radiator 4 needs to be activated. Simultaneously with activating axial fan 3, power source 284 should be started, thereby driving guide plate 283 to rotate to the second state, as shown below. Figure 10 As shown.

[0073] At this time, the outside air flows horizontally along the guide plate 283, which increases the time that the air stays in the air cooler body 1, so that the radiator 4 can effectively cool the air.

[0074] When the ambient air temperature is within the T3 range, the radiator 4 and the spray mechanism 2 need to be activated. Simultaneously with starting the axial flow fan 3, the second power source 284 is activated, thereby driving the guide plate 283 to rotate to the third state, as shown below. Figure 10 As shown.

[0075] At this time, the outside air flows obliquely downward along the guide plate 283, which further increases the time that the air stays in the air cooler body 1. In addition, the obliquely downward flowing air comes into contact with the water surface of the water storage chamber, thereby achieving further cooling of the air and improving the cooling effect.

[0076] As can be seen from the above, by setting the flow guide component 28, the flow guide plate 283 can be rotated to different states according to different ambient temperatures, thereby realizing the flow of air entering the inner cavity of the air cooler body 1 in different states, and thus effectively improving the heat dissipation and cooling effect of the inner cavity of the air cooler body 1.

[0077] It should be noted that the second power source 284 is preferably an electric motor.

[0078] The spray mechanism 2 also includes: a cleaning assembly 29 for cleaning the filter screen 281; the cleaning assembly 29 includes: a second reciprocating screw 292 rotatably mounted in the mounting frame 282, a drive component 291 drively mounted between the second reciprocating screw 292 and the guide plate 283; a brush 293 threadedly connected to the second reciprocating screw 292; a fixing rod 294 for limiting the brush 293, both ends of the fixing rod 294 being fixedly mounted in the mounting frame 282; and a cleaning component 299 for cleaning the filter screen 281. A collection box 296 for collecting dust on 81 is fixedly installed at the bottom of the mounting frame 282. The bottom of the mounting frame 282 has a collection opening 1, and the top of the collection box 296 has a collection opening 2, and the collection opening 1 and the collection opening 2 are connected to each other. An air pump 295 is fixedly installed on the mounting frame 282. An air outlet pipe 298 connects the air outlet of the air pump 295 to the air outlet of the guide plate 283. An air inlet pipe 297 connects the air inlet of the air pump 295 to the air inlet of the collection box 296.

[0079] The rotating shaft is a hollow tube, and the guide plate 283 is a rectangular plate with a cavity. The guide plate 283 has an air outlet that is connected to the cavity. Each rotating shaft is connected to the adjacent guide plate 283. The air outlet pipe 298 is connected to each rotating shaft, and the air outlet end of the air outlet pipe 298 is rotatably connected to the rotating shaft. A filter plate is installed in the collection box 296, so that the gas drawn by the air pump 295 is clean gas. The collection box 296 is equipped with a sealing door. When it is necessary to clean the dust collected in the collection box 296, the sealing door can be opened for cleaning.

[0080] When cleaning the filter screen 281, the air pump 295 and the second power source 284 are started. The second power source 284 can drive multiple guide plates 283 to rotate synchronously, and drive the second reciprocating screw 292 to rotate through the drive component 291. Under the limiting action of the fixed rod 294, the brush 293 moves back and forth along the axis of the second reciprocating screw 292. Through the reciprocating movement of the brush 293, the dust on the air intake side of the filter screen 281 can be cleaned, ensuring the filtration effect of the filter screen 281.

[0081] The dust that falls off the cleaning system enters the collection box 296 through collection opening one and collection opening two for collection. At the same time, the air pump 295 draws air from the collection box 296 through the air inlet pipe 297, creating a negative pressure inside the collection box 296. This causes outside air to enter the collection box 296 through collection opening one and collection opening two, and the dust that falls off the cleaning system quickly enters the collection box 296 with the airflow, improving the dust collection efficiency.

[0082] Because a filter plate is installed inside the collection box 296, the gas drawn by the air pump 295 is clean gas, which passes through the air outlet pipe 298 and the rotating shaft in sequence, enters the guide plate 283, and is then discharged through the air outlet. As the guide plate 283 rotates circumferentially along the rotating shaft, the high-pressure gas discharged through the air outlet cleans the filter screen 281, thereby further improving the cleaning effect on the filter screen 281.

[0083] In addition, the rotation of the baffle 283 allows the high-pressure gas discharged from the vent to clean the inside of the mounting frame 282 and the baffle 283 itself.

[0084] It should be noted that the drive component 291 is preferably a timing pulley and a timing belt.

[0085] In this invention, the spray mechanism 2 can spray water mist onto the radiator 4 and stir the water in the water storage chamber to make it cool evenly. It can also guide the air entering the inner cavity of the air cooler body 1 in different states according to the ambient temperature, thereby effectively improving the heat dissipation and cooling effect of the inner cavity of the air cooler body 1.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
