Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically to a cooling tower flow guiding device. Background Technology

[0002] A cooling tower is a large piece of equipment used to reduce the temperature of circulating water in industrial production or air conditioning systems. Its core principle is to spray hot water into fine droplets or form a water film, which fully contacts the air flowing inside the tower. The water absorbs heat through evaporation and the temperature difference between the air and the water is used for heat transfer, so that the water temperature is reduced and then flows back into the system for reuse.

[0003] However, many existing cooling towers do not have filter components installed at the air inlet and outlet, which causes a large amount of dust and insects to enter the cooling tower. This not only pollutes the water source, but also causes foul smells and siltation over time. In addition, the continuous dripping of a large amount of water during the operation of traditional cooling towers makes the surrounding environment very noisy.

[0004] Therefore, there is an urgent need to propose a cooling tower airflow guiding device to prevent dust and insects from entering the device, thereby avoiding water pollution or even damage to the equipment, and reducing the noise level when the device is working. Utility Model Content

[0005] The purpose of this invention is to provide a cooling tower airflow guiding device to solve the above problems. This device can effectively prevent dust and insects from entering the device, thereby avoiding water pollution or even damage to the equipment. It can also reduce the noise intensity of the device during operation.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a cooling tower flow guiding device, comprising a cooling tower, wherein a receiving baffle is horizontally fixedly connected to the inner wall of the cooling tower, and a plurality of drainage holes are evenly spaced on the receiving baffle. A water guiding and heat conducting upright is fixedly connected to the inner wall of the bottom side of each drainage hole. Two stepped water flow umbrella frames are fixedly fixed at the top of each water guiding and heat conducting upright at intervals. The stepped water flow umbrella frames fixed on two adjacent water guiding and heat conducting uprights are vertically staggered. Three air inlet pipes are evenly spaced and connected through the four sides of the cooling tower, and the air inlet pipes are located on the top side of the receiving baffle. An air collecting horn is fixedly connected to the outer end of each air inlet pipe, and an air inlet filter is fixedly connected to the inner wall of the air collecting horn.

[0007] Preferably, a bearing seat is fixedly installed on the inner wall of the outer end of the air inlet pipe, and a rotating rod that penetrates the air inlet filter is rotatably installed on the bearing seat. Three dust scraper rods are fixedly connected in a circular array at the end of the rotating rod away from the bearing seat. The dust scraper rods are in contact with the air inlet filter, and a passive fan is also fixedly installed on the rod body.

[0008] Preferably, a flow divider plate is fixedly installed on one side of the outer wall of the cooling tower, and a booster water pump is fixedly installed in the middle of one side of the flow divider plate. A water inlet pipe is detachably connected to one side of the booster water pump.

[0009] Preferably, the diverter plate is attached to one side of the cooling tower, penetrates the cooling tower, and is uniformly spaced and fixedly connected with multiple spray plates. The ends of the spray plates away from the diverter plate are fixedly connected to the inner wall of the cooling tower. Multiple nozzles are uniformly spaced on the bottom side of each spray plate.

[0010] Preferably, the top side of the cooling tower is connected and fixed with an air outlet frame, the inner wall of the top side of the air outlet frame is horizontally fixed with an air outlet filter, and the bottom side of the air outlet filter is provided with a cooling fan fixedly installed on the inner wall of the air outlet frame.

[0011] Preferably, a packing layer is fixedly installed on the inner wall of the cooling tower between the spray plate and the receiving partition, and a water outlet pipe is fixedly connected to the cooling tower and the water outlet pipe is located on the bottom side of the receiving partition.

[0012] Compared with the prior art, the present invention provides a cooling tower flow guiding device, which has the following beneficial effects: This invention effectively blocks dust and insects from the outside air from entering the cooling tower by setting up an inlet air filter and an outlet air filter, preventing water pollution and equipment damage due to the accumulation of impurities. At the same time, the passive fan at the outer end of the inlet air pipe will rotate under the action of airflow, driving the rotating rod and dust scraper to rotate, so that the dust scraper continuously cleans the surface of the inlet air filter, preventing the filter from being clogged and affecting the air intake efficiency, and reducing the frequency of manual cleaning. This invention features a stepped water flow umbrella frame. Water dripping from the bottom of the packing layer first contacts the stepped water flow umbrella frame and slides down step by step. The umbrella frame structure effectively buffers the water flow, allowing it to slide down step by step and finally drip onto the receiving partition. The water then flows out through the drain hole and slides naturally down the body of the water-conducting and heat-conducting upright. This process avoids the impact caused by the water droplets falling directly into the air, significantly reducing the noise during device operation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 3-6As shown, this utility model provides a cooling tower flow guiding device, including a cooling tower 1. A receiving baffle 17 is horizontally fixedly connected to the inner wall of the cooling tower 1. A plurality of drainage holes 18 are evenly spaced on the receiving baffle 17. A water guiding and heat conducting upright 19 is fixedly connected to the inner wall of the bottom side of the cooling tower 1 in the middle of each drainage hole 18. Two stepped water flow umbrella frames 20 are fixedly fixed at the top of each water guiding and heat conducting upright 19 at intervals. The stepped water flow umbrella frames 20 fixed on two adjacent water guiding and heat conducting upright 19 are vertically staggered. Three air inlet pipes 11 are evenly spaced and connected through the four sides of the cooling tower 1. The air inlet pipes 11 are located on the top side of the receiving baffle 17. An air collecting horn 12 is fixedly connected to the outer end of each air inlet pipe 11. An air inlet filter 13 is fixedly connected to the inner wall of the air collecting horn 12. The support plate 17 provides support for the upper structure, while the drainage holes 18 on it allow water to flow through and reach the bottom of the cooling tower 1. The stepped water umbrella frame 20 can catch the water dripping from above, allowing the water to slide down its steps alternately, thus acting as a buffer. At the same time, the water-guiding and heat-conducting uprights 19 can conduct the heat of the water flow, facilitating heat exchange with the air. The air inlet duct 11 is the channel for outside air to enter the cooling tower 1. The air intake horn 12 can improve the air intake efficiency, while the air inlet filter 13 can filter dust and insects in the air, preventing them from entering the cooling tower 1 and contaminating the water source or damaging the equipment.

[0016] For further details, please refer to Figure 5 A bearing seat 14 is fixedly installed on the inner wall of the outer end of the air inlet pipe 11. A rotating rod 15, penetrating the air inlet filter 13, is rotatably mounted on the bearing seat 14. Three dust scraper rods 16 are fixedly connected in a circular array at the end of the rotating rod 15 away from the bearing seat 14. The dust scraper rods 16 are in contact with the air inlet filter 13. A passive fan 22 is also fixedly installed on the body of the rotating rod 15. The bearing seat 14 provides rotational support for the rotating rod 15, allowing it to rotate smoothly. The passive fan 22 rotates under the action of airflow, thereby driving the rotating rod 15 to rotate, which in turn drives the dust scraper rods 16 to rotate. The dust scraper rods 16 can clean the dust on the surface of the air inlet filter 13, preventing the filter from becoming clogged.

[0017] For further details, please refer to Figure 1 and Figure 3 A flow divider plate 2 is fixedly installed on one side of the outer wall of the cooling tower 1. A booster water pump 3 is fixedly installed in the middle of one side of the flow divider plate 2. A water inlet pipe 4 is detachably connected to one side of the booster water pump 3. The booster water pump 3 provides power for the delivery of hot water, allowing the hot water to enter the flow divider plate 2 through the water inlet pipe 4. The flow divider plate 2 is used to distribute the hot water and then evenly deliver it to each spray plate 5.

[0018] For further details, please refer to Figure 3The diversion plate 2 is attached to one side of the cooling tower 1, penetrates the cooling tower 1, and is uniformly spaced and fixedly connected to multiple spray plates 5. The ends of the spray plates 5 away from the diversion plate 2 are fixedly connected to the inner wall of the cooling tower 1. Multiple nozzles 6 are uniformly spaced on the bottom side of each spray plate 5. The spray plates 5 are used to transport the hot water distributed by the diversion plate 2 to each nozzle 6, and the nozzles 6 spray the hot water evenly to form a water mist, increasing the contact area between the hot water and the air and improving the cooling effect.

[0019] For further details, please refer to Figure 2 The cooling tower 1 has an air outlet frame 7 fixedly connected to its top side. An air outlet filter 8 is horizontally fixedly connected to the inner wall of the top side of the air outlet frame 7. A cooling fan 9, fixedly installed on the inner wall of the air outlet frame 7, is located on the bottom side of the air outlet filter 8. The air outlet frame 7 serves as a channel for hot air to exit the cooling tower 1. The air outlet filter 8 prevents external impurities from entering the cooling tower 1 and also blocks water from splashing out of the tower. The cooling fan 9 drives the hot air inside the cooling tower 1 to flow upwards and exit through the air outlet filter 8, accelerating air circulation and improving cooling efficiency.

[0020] For further details, please refer to Figure 1 and Figure 3 A packing layer 10, fixedly installed on the inner wall of the cooling tower 1, is provided between the spray plate 5 and the receiving baffle 17. A water outlet pipe 21 is fixedly connected to the cooling tower 1 and is located on the bottom side of the receiving baffle 17. The packing layer 10 increases the contact area between the water flow and the air, promoting heat exchange. The water outlet pipe 21 is used to discharge the cooled water from the cooling tower 1 for recycling.

[0021] The working principle of the cooling tower flow guiding device provided by this utility model is as follows: First, the hot water requiring cooling enters the distribution plate 2 through the inlet pipe 4 under the action of the pressurized water pump 3. After being distributed by the distribution plate 2, it is delivered to each spray plate 5, and then evenly sprayed by the nozzles 6 on the bottom side of the spray plate 5 to form a water mist. This water mist is evenly sprayed on the upper surface of the packing layer 10 and forms a water flow within the packing layer 10. After the hot water initially contacts and exchanges heat with the air in the packing layer 10, it drips from the bottom side of the packing layer 10, first contacting the stepped water umbrella frame 20, and then sliding down the stepped water umbrella frame 20 step by step, transferring heat to the stepped water umbrella frame 20 and the water-conducting and heat-conducting uprights 19 connected to it. The water finally drips onto the receiving baffle 17, and then flows out through the drain hole 18 on the receiving baffle 17, and then along the... The water-conducting and heat-conducting support rod 19 slides naturally to the bottom of the cooling tower 1, and is finally discharged through the outlet pipe 21 for recycling. At the same time, outside air, affected by the internal air pressure of the device, enters the device through the air collector horn 12. After being filtered by the air inlet filter 13 to remove dust and insects, it enters the interior of the cooling tower 1 from the inner end of the air inlet pipe 11. This cold air directly contacts the top of the water-conducting and heat-conducting support rod 19 and the stepped water umbrella frame 20, absorbing heat from both and rising upwards. It then comes into full contact with the water in the packing layer 10 and the water mist sprayed by the nozzles 6, further absorbing heat through heat exchange and water evaporation. Finally, the hot air carrying a large amount of heat is discharged from the outside of the cooling tower 1 through the outlet filter 8 under the action of the cooling fan 9 in the outlet frame 7. During this process, the air flow drives the passive fan 22 in the air inlet pipe 11 to rotate. The passive fan 22 drives the dust scraper 16 to rotate on the surface of the air inlet filter 13 through the rotating rod 15, which removes the dust on the filter in time to ensure smooth air intake.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
