Description

Technical Field

[0001] The invention relates to the technical field of open cooling towers, in particular to a high-efficiency open cooling tower. Background Art

[0002] The cooling tower achieves the purpose of cooling by increasing the contact area between water and air, and then using the circulation of normal temperature air in the atmosphere to carry away the heat in the high-temperature water. The cooling tower consists of a tower body, a water distribution system, a water sprinkling device, a ventilation system and a water collection tank. The open cooling tower is a means inside a sealed structure. By spraying circulating water onto the filler in a spray manner, the filler provides a larger contact surface, and the heat exchange effect is achieved through the contact between water and air. The fan then drives the air circulation in the tower to carry out the hot air flow after the heat exchange with the water, thereby achieving cooling.

[0003] However, during actual use, the inventors found that the packing was set up in a static manner. At the same time, a zigzag channel was set inside the packing to increase the heat exchange time between the air and the water film. When the water mist fell from above, the water mist would be concentrated on one side of the channel due to gravity. This caused the water films on both sides of the inner wall of the channel to be in an unbalanced state, which was not conducive to more efficient cooling work. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and, by providing a cooling mechanism and a cleaning mechanism, solve the technical problems that when water mist is distributed inside the filler, the water film formed is not balanced, resulting in a reduced cooling effect, and the equipment is in direct contact with the air, resulting in the accumulation of impurities and reducing its own life.

[0012] Preferably, the oscillation assembly includes two groups of first rotating shafts respectively connected to the first mounting frame, a ratchet gear connected to the first rotating shaft, multiple groups of long rods corresponding to the ratchet gears arranged on the driving rod, a second rotating shaft connected to the long rod, a half gear connected to the second rotating shaft and meshing with the ratchet gear for transmission, and a torsion spring connected between the half gear and the long rod.

[0013] Preferably, the cleaning mechanism includes a switching component provided on the tower body and used to alternately move the two groups of filling components, a cleaning component provided on the tower body and used to clean the filling components, and a collecting component provided on the tower body and used to uniformly collect and process impurities.

[0014] Preferably, the switching assembly includes a first driving cylinder connected to the tower body, a ring connected to the output end of the first driving cylinder, a first guide groove and a second guide groove opened in the ring and connected to each other, a protrusion connected to the ring, a block connected to the mounting frame, and a round rod connected to the tower body through a second spring and cooperating with the first guide groove and the second guide groove to drive the ring to rotate.

[0016] The collecting assembly includes a screening trough opened on and connected to the tower body, a screening plate connected to the screening trough, a supporting frame connected to the circular ring, a push plate connected to the supporting frame through a second telescopic member, two groups of hanging ears connected to the push plate, two groups of guide rods connected to the tower body and having mounting grooves, multiple groups of receiving blocks connected to the tower body and located in the mounting grooves, and a third spring connected between the receiving blocks and the guide rods.

[0017] Preferably, the protection mechanism includes a recovery component provided on the tower body and used to collect the water to be cooled on the inner wall and discharge it centrally, and a cooling component provided on the tower body and used to cool the inner wall of the tower body.

[0020] Beneficial effects of the present invention:

[0021] (1) The present invention provides a cooling mechanism in which the filling component and the regulating component cooperate to enable the filling layer to perform cooling in a dynamic manner. During the process, the bending direction of the zigzag channel is continuously changed so that the water mist falling from above can be evenly distributed around the channel, ensuring as much as possible that the thickness of the water film formed in the channel is balanced, thereby achieving the best contact heat exchange effect between water and air;

[0022] (2) In the present invention, by providing an oscillating component in the cooling mechanism, the water film on the filling component can be updated in time. Since the cooling medium of the open cooling tower is air in the atmosphere, in this state, a small amount of dust and impurities in the air may adhere to the filling component. When the water flow cannot flush it, its presence slows down the speed of the water film's falling and updating, thereby affecting the cooling efficiency.

[0023] (3) The present invention provides a cleaning mechanism so that the two groups of filling components can alternately perform cooling work, and the replaced filling component can fully clean itself, remove dust and impurities from the air attached to itself, ensure its own cooling capacity while extending its service life, and collect the cleaned impurities to prevent them from flowing back to the bottom of the tower body, thereby extending the service life of the cooling water;

[0024] (4) In the present invention, a protective mechanism is provided and a recovery component and a cooling component are used in combination. While collecting the circulating water attached to the periphery of the tower body and spraying it toward the center, the circulating water at the bottom that has completed the cooling work is driven to circulate around the tower body. This ensures that the circulating water around the tower body will not flow down in streams, affecting the cooling effect. It also ensures that the temperature of the upper part of the tower body will not always remain high due to the effect of the water mist when it is just sprayed out.

[0025] In summary, the equipment has the advantages of good cooling effect, long equipment life, and not easy to cause blockage during the cooling process. It is particularly suitable for the field of open cooling tower technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figures 1 to 3 As shown, a high-efficiency open cooling tower comprises:

[0048] A cooling mechanism 1 is provided in the tower body 100 and is used to increase the contact area between the water to be cooled and the air;

[0049] A cleaning mechanism 2, which is provided on the tower body 100 and is used to clean impurities from the cooling mechanism 1;

[0050] A protection mechanism 3, which is provided on the tower body 100 and is used to collect and process the water to be cooled that is attached to the inner walls around the tower body 100;

[0051] The cooling mechanism 1 includes two groups of filling components 11 arranged upper and lower on the tower body 100 and used to increase the water film area, a regulating component 12 arranged on the filling component 11 and used to adjust the structural state of the filling component 11, and an oscillation component 13 arranged on the regulating component 12 and used to drive the filling component 11 to vibrate and accelerate the renewal of the water film.

[0052] In this embodiment, a cooling mechanism 1 is provided, in which the filling component 11 and the regulating component 12 cooperate to enable the filling layer to perform cooling work in a dynamic manner. During the process, the bending direction of the zigzag channel is continuously changed so that the water mist falling from above can be evenly distributed around the channel, ensuring that the thickness of the water film formed in the channel is as balanced as possible, thereby achieving the best contact heat exchange effect between water and air.

[0053] In detail, first, high-temperature circulating water is sprayed out from the spray device at the top of the tower body 100, and then falls on the cooling mechanism 1. Under the action of the fan at the top of the tower body 100, the air and water mist form convection, thereby completing the cooling work. During the process, the cleaning mechanism 2 moves the two groups of filling components 11 alternately, and then cleans the filling components 11. During the entire cooling work, the protective mechanism 3 collects and discharges the water droplets formed on the inner wall of the tower body 100 close to the spray device, and maintains the temperature balance at this position.

[0054] It should be noted that the bottom size of the tower body 100 is a 6m*6m square setting, and the material is fiberglass. The equipment is connected by bolts. At the same time, after the whole is in place, the gap between the two equipment is sealed with a sealing plate to ensure the overall appearance. The tower body 100 and the embedded iron of the on-site foundation are fully welded. The upper surface heights of multiple tower bodies 100 are on the same horizontal plane with an error of less than ±2MM. The circulating water pump should be lower than the tower body to ensure that the water pump operates normally. A certain distance (≥2.5 meters) must be maintained between the tower body 100 and parallel buildings. Avoid installation next to fire passages or high walls that are prone to reflecting noise. Avoid installation downwind of heat sources, dust or corrosive gases, and reserve space for cooling water pipeline layout, personnel maintenance and other necessary locations.

[0055] Further, if Figures 2 to 4 As shown, the filling assembly 11 includes a mounting frame 111 arranged in the tower body 100, two groups of first mounting frames 113 connected to the mounting frame 111 through first telescopic members 112, multiple groups of first fold-line rods 114 connected to the first mounting frames 113, a nylon film 115 arranged between the upper and lower groups of first fold-line rods 114, a second fold-line rod 116 connected to the middle position of the nylon film 115, and a second mounting frame 117 connected to the multiple groups of second fold-line rods 116.

[0056] In this embodiment, two groups of first mounting frames 113 connected to the mounting frame 111 by first telescopic members 112 are provided, and the elastic deformation of the first telescopic members 112 is utilized to neutralize the tension during the shape change of the nylon film 115, thereby ensuring the service life of the nylon film 115 during operation.

[0057] In detail, when the second mounting frame 117 is driven, it drives the plurality of second fold line rods 116 to move, thereby changing the original vertical channel to a fold line shape from the middle position of the nylon film 115, thereby increasing the contact time between the airflow and the water film.

[0058] It should be noted that nylon film 115 has the following characteristics: it is very tough, has good transparency, high tensile strength and tensile strength, good heat resistance, cold resistance, oil resistance and organic solvent resistance, excellent wear resistance and puncture resistance, which is conducive to cooling work in open cooling towers and can adapt to various work needs.

[0059] Further, if Figures 2 to 7 and Figure 9 As shown, the regulating assembly 12 includes two groups of slot plates 121 connected to the mounting frame 111, two groups of first springs 122 connected to the slot plates 121, two groups of L-shaped rods 123 connected to the second mounting frame 117 and located in the slot plates 121, a driving rod 124 connected to the tower body 100, two groups of driving blocks 125 connected to the driving rod 124, and a triangular block 126 connected to the tower body 100.

[0060] In this embodiment, by setting up the regulating component 12, the bending direction of the fold line channel formed by the filling component 11 during the cooling process can be changed, with back and forth interaction similar to the upper left and lower right directions. The four surfaces of the fold line channel are changed from opportunities to the state of maximum contact surface with the water mist, thereby ensuring the balance of water film formation inside the filling component 11.

[0061] In detail, when the filling assembly 11 is working, the driving rod 124 starts to move up and down, and the L-shaped rod 123 is squeezed by the driving block 125 to move inside the slot plate 121. When the L-shaped rod 123 is squeezed to the maximum distance, the driving block 125 passes over the L-shaped rod 123, and the L-shaped rod 123 is reset a short distance under the action of the first spring 122, for the next squeezing action with the driving block 125. At this time, the L-shaped rod 123 drives the second mounting frame 117 to move, and the second mounting frame 117 drives the nylon film 115 through multiple second folding rods 116 to complete a transformation; when the filling assembly 11 is evacuated horizontally for cleaning, under the squeezing action of the triangular blocks 126 on both sides, the second mounting frame 117 returns to the middle position, and makes the nylon film 115 vertical.

[0062] It should be noted that a damper is provided between the slot plate 121 and the L-shaped rod 123 to prevent the filling assembly 11 from automatically resetting.

[0063] Further, if Figure 3 to Figure 2 and Figure 8As shown, the oscillation assembly 13 includes two groups of first rotating shafts 131 respectively connected to the first mounting frame 113, a ratchet gear 132 connected to the first rotating shaft 131, multiple groups of long rods 133 corresponding to the ratchet gears 132 set on the driving rod 124, a second rotating shaft 134 connected to the long rod 133, a half gear 135 connected to the second rotating shaft 134 and engaged with the ratchet gear 132 for transmission, and a torsion spring 136 connected between the half gear 135 and the long rod 133.

[0064] In this embodiment, by providing an oscillation component 13 in the cooling mechanism 1, the water film on the filling component 11 can be updated in time. Since the cooling medium of the open cooling tower is air in the atmosphere, in this state, dust and impurities in the air may be slightly attached to the filling component 11. When the water flow cannot flush it, its presence slows down the falling and updating speed of the water film, thereby affecting the cooling efficiency.

[0065] In detail, while the driving rod 124 drives the regulating component 12 to work, taking the downward movement as an example, the long rod 133 connected to the driving rod 124 drives the corresponding half gear 135 to engage and transmit with the ratchet gear 132 below. At this time, the half gear 135 passes over the ratchet gear 132 by meshing and maintains its original state. Then, when moving upward, since the ratchet gear 132 cannot rotate in the opposite direction, the half gear 135 rotates itself under the squeezing action with the ratchet gear 132, and the torsion spring 136 accumulates elastic force. At the same time, the first mounting frame 113 is slightly lifted. When it rotates to a certain angle, the first gear tooth of the half gear 135 passes over the ratchet gear 132, and under the action of the torsion spring 136, the second gear tooth rotates rapidly and is squeezed by the ratchet gear, and then cooperates with the first mounting frame 113 connected to the first telescopic member 112 to drive the nylon film 115 to complete multiple vibrations and update its own water film.

[0066] Further, if Figure 10 As shown, the cleaning mechanism 2 includes a switching component 21 arranged on the tower body 100 and used to alternately move the two groups of filling components 11, a cleaning component 22 arranged on the tower body 100 and used to clean the filling components 11, and a collecting component 23 arranged on the tower body 100 and used to uniformly collect and process impurities.

[0067] In this embodiment, by setting up a cleaning mechanism 2, the two groups of filling components 11 can perform cooling work alternately, and the replaced filling component 11 can fully perform its own cleaning work, remove the dust and impurities attached to itself from the air, ensure its own cooling capacity while extending its service life, and at the same time collect the cleaned impurities to prevent them from flowing back to the bottom of the tower body 100, thereby extending the service life of the cooling water.

[0068] In detail, first, during operation, the switching component 21 alternately withdraws the two groups of filling components 11, and the withdrawn filling components 11 remove their own impurities under the action of the cleaning component 22. After the impurities fall, they are uniformly collected and processed by the collecting component 23.

[0069] Further, if Figures 11 to 10 and Figures 13 to 15 As shown, the switching assembly 21 includes a first driving cylinder 211 connected to the tower body 100, a ring 212 connected to the output end of the first driving cylinder 211, a first guide groove 213 and a second guide groove 214 opened in the ring 212 and connected to each other, a protrusion 215 connected to the ring 212, a block 216 connected to the mounting frame 111, and a round rod 218 connected to the tower body 100 via a second spring 217 and cooperating with the first guide groove 213 and the second guide groove 214 to drive the ring 212 to rotate.

[0070] In this embodiment, a switching component 21 is provided so that the two groups of filling components 11 can work alternately and be maintained through cleaning to extend their service life. In order to prevent the two layers of filling components 11 from enhancing the airflow interception effect and reducing the airflow circulation effect during switching, thereby causing the problem of reduced heat exchange effect, the cleaned filling components 11 are put in place in a vertical channel state during the replacement process, and then the other group of filling components 11 starts to move out quickly. At the same time, the channel states of the two groups of filling components 11 are switched between vertical and broken lines, respectively, thereby ensuring smooth airflow and stable cooling effect.

[0071] In detail, first, taking the cleaning of the lower filling component 11 as an example, the first driving cylinder 211 drives the ring 212 to move through the output end, and the ring 212 pushes the lower filling component 11 to move. As the lower filling component 11 is in place, the round rod 218 connected to the tower body 100 is stuck in the first guide groove 213 in the ring 212. As the ring 212 moves, the round rod 218 continuously squeezes the first guide groove 213, thereby causing the ring 212 to rotate, and the round rod 218 also enters the second guide groove 214 along the first guide groove 213. During the process, due to the gradual decrease in the depth of the first guide groove 213, the round rod 218 is inserted into the second guide groove 214. The rod 218 also compresses the second spring 217, and the lower filling component 11 is now in place. Next, the output end of the first driving cylinder 211 begins to reset. Due to the cooperation between the round rod 218 and the round rod 218, the ring 212 rotates 180°, and the protrusion 215 connected to the ring 212 also rotates 180°. At this time, when the ring 212 is reset, the protrusion 215 pulls the block 216 on the upper filling component 11, thereby driving the upper filling component 11 to evacuate for cleaning. During the process, the round rod 218 moves relatively along the second guide groove 214, and is reset by the second spring 217 after withdrawal.

[0072] It should be noted that the upper and lower edges of the ring 212 overlap with the two groups of filling components 11 in the horizontal position, which is used to push the filling components 11 to the working position; the first guide groove 213 is arranged in an arc shape, and its depth is arranged from deep to shallow. The depth of the second guide groove 214 connected to it is consistent with the depth of the shallowest position of the first guide groove 213. Therefore, when the round rod 218 just enters the first guide groove 213 on the ring 212, due to the height difference between the first guide groove 213 and the second guide groove 214, the round rod 218 can only move along the first guide groove 213.

[0073] Further, if Figures 10 to 12 As shown, the cleaning assembly 22 includes two groups of reciprocating screws 222 connected to the tower body 100 and connected through a belt transmission member 221, a motor 223 connected to the tower body 100 and having its output end connected to one side of the reciprocating screw 222, a moving frame 224 connected to the two groups of reciprocating screws 222, a plurality of cleaning brushes 225 penetrating the tower body 100 and connected to the moving frame 224, and a plurality of nozzles 226 arranged on the tower body 100;

[0074] The collecting assembly 23 includes a screening trough 230 opened on the tower body 100 and connected to the tower body 100, a screening plate 231 connected to the screening trough 230, a supporting frame 232 connected to the ring 212, a push plate 234 connected to the supporting frame 232 through a second telescopic member 233, two groups of hanging ears 235 connected to the push plate 234, two groups of guide rods 237 connected to the tower body 100 and having installation grooves 236, multiple groups of receiving blocks 238 connected to the tower body 100 and located in the installation grooves 236, and a third spring 239 connected between the receiving blocks 238 and the guide rods 237.

[0075] In this embodiment, the filling component 11 can be changed by setting the matching shape of the cleaning component 22, so that the filling component 11 can improve the cooling effect during the cooling process. At the same time, the folded channel can be adjusted to a vertical state during the self-cleaning process to facilitate cleaning. In addition, the impurities cleaned by the collecting component 23 are collected separately and will not return to the circulating water, which is beneficial to reduce the number of times the circulating water is replaced.

[0076] In detail, taking the cleaning of the lower filling component 11 as an example, first, the motor 223 drives the two sets of reciprocating screws 222 to rotate through the belt transmission part 221, thereby making the movable frame 224 and the cleaning brush 225 connected to the reciprocating screw 222 move up and down. In the process, the nylon film 115 is cleaned through the vertical channel after the filling component 11 is changed, and then the impurities are dropped by the nozzle 226. When the lower cleaning component needs to be changed to the working state, the lower filling component 11 starts to move into place under the push of the first driving cylinder 211. In the process, the supporting frame 232 connected to the ring 212 drives the push plate 234 to move. When passing the guide rod 237, due to the limitation of the guide rod 237 by the receiving block 238, the hanging ear 235 tilts along the guide rod 237. The inclined surface drives the push plate 234 to move upward, and the second telescopic part 233 contracts. After reaching the farthest position, the hanging ear 235 separates from the guide rod 237, and the push plate 234 is reset under the action of the second telescopic part 233. Then the first driving cylinder 211 is reset and drives the upper filling assembly 11 to move out of the working position. At the same time, the push plate 234 also pushes the impurities and circulating water together. During the process, the hanging ear 235 squeezes the guide rod 237 to move it upward to avoid it, and then resets it through the third spring 239. When the push plate 234 reaches the screening plate 231, it moves along the screening plate 231 under the action of the second telescopic part 233 and concentrates the impurities on one side, while the remaining circulating water passes through the screening plate 231 into the screening tank 230, and finally returns to the bottom of the tower body 100.

[0077] It should be noted that the distance that the movable frame 224 and the cleaning brush 225 can move up and down can meet the cleaning work of two groups of filling components 11, and the bottom of the push plate 234 is a silicone layer.

[0078] Further, if Figure 2 and Figures 17 to 16 As shown, the protection mechanism 3 includes a recovery component 31 provided on the tower body 100 and used to collect the water to be cooled on the inner wall and discharge it centrally, and a cooling component 32 provided on the tower body 100 and used to cool the inner wall of the tower body 100.

[0079] It is worth mentioning here that since the spraying device sprays hot water all around, the spraying state makes the water mist evenly dispersed in the middle of the heat dissipation material, and cooperates with the heat dissipation material to achieve stable cooling, but there is also some water mist in the spraying, which always accumulates around the inner wall of the device and concentrates downward through the edge of the heat dissipation material. Therefore, by setting up a protective mechanism 3, this part of the water to be circulated can be well collected and processed, and the temperature of the tower body 100 can be maintained.

[0080] In detail, during the operation, the recovery component 31 collects the circulating water accumulated on the tower body 100 between the spray device and the upper filling component 11 and sprays it toward the center. At the same time, the cooling component 32 drives the circulating water cooled at the bottom upward to absorb the heat of the absorption part to maintain the temperature of the tower body 100.

[0081] Further, if Figure 16 As shown, the recovery component 31 includes a water collecting plate 311 connected to the tower body 100 and having multiple spray holes 310, a scraper 312 connected to the tower body 100 and connected to the driving rod 124, and a second driving cylinder 313 connected to the tower body 100 and having an output end connected to the scraper 312.

[0082] In this embodiment, by providing the recovery assembly 31, the technical problem that there is a lot of water around the tower body 100 and heat exchange with the air can only be carried out through the edge of the heat dissipation material, which ultimately causes the temperature drop to fail to achieve the expected effect is solved.

[0083] In detail, driven by the second driving cylinder 313, the scraper 312 moves up and down to push the water on the tower body 100 to the water collecting plate 311, and under the interlocking and squeezing of the scraper 312 and the water collecting plate 311, the pressure drives the water to spray out from multiple spraying positions toward the center.

[0084] It should be noted that the power of the regulating component 12 and the oscillation component 13 also comes from the second driving cylinder 313. When the scraper 312 moves upward, the inclination of its own top causes the water on the tower body 100 to be scraped off and flow along the slope, and fall down along the bottom at the edge to the water collecting plate 311.

[0085] Example 2

[0086] like Figure 2 and Figures 17 and 18 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0087] Furthermore, the cooling component 32 includes an extrusion groove 320 opened on the tower body 100, an extrusion plate 321 connected to the extrusion groove 320 and connected to the driving rod 124, a cooling pipe 322 arranged in the tower body 100, and an input pipe 323 connected between the extrusion groove 320 and the cooling pipe 322.

[0088] It is worth mentioning that by providing the cooling component 32 and cooperating with the power of the recovery component 31, the bottom circulating water is used to maintain the temperature of the tower body 100 itself, which is conducive to ensuring the service life of the tower body 100 while making full use of the power.

[0089] In detail, when the driving rod 124 drives the extrusion plate 321 to move downward, the circulating water begins to flow into the extrusion groove 320, and then when the extrusion plate 321 moves upward, the circulating water enters the cooling pipe 322 through the input pipe 323 and is stored for cooling. When it goes through another cycle, the circulating water in the previous group of cooling pipes 322 is squeezed out and transported to the spray device.

[0090] It should be noted that one-way valves are respectively provided on the input pipe 323 and the extrusion groove 320; and the cooling pipe 322 is provided in the inner wall of the tower body.

[0091] Working process:

[0092] First, high-temperature circulating water is sprayed from the spray device at the top of the tower body 100 and then falls onto the cooling mechanism 1. The filling component 11 helps expand its surface area to form a water film. Under the action of the fan at the top of the tower body 100, the air and the water film form convection, thereby completing the cooling work. During this process, the control component 12 drives the filling component 11 to intermittently change the channel state, ensuring the balanced formation of the water film inside the filling component 11. In conjunction with the oscillation component 13, the water film on the filling component 11 can be updated in a timely manner.

[0093] During the cooling process, the switching component 21 in the cleaning mechanism 2 moves the two groups of filling components 11 alternately, and then the filling components 11 are cleaned by the cleaning component 22. Under the power of the switching component 21, the collecting component 23 collects and processes the cleaned impurities in a centralized manner;

[0094] During the entire cooling operation, the protection mechanism 3 collects and discharges the water droplets formed on the inner wall of the tower body 100 and the part close to the spray device through the recovery component 31, and drives the circulating water at the bottom of the tower body 100 through the cooling component 32 to maintain the temperature above the tower body 100 balanced.
