AI Technical Summary
Traditional cooling towers generate a large amount of water vapor during operation, which increases the humidity in the surrounding area and causes corrosion damage.
The defogging cooling tower uses spray water to enhance heat and mass transfer. Low-temperature cooling water is sprayed from the spray head and comes into contact with water vapor, causing the water vapor to condense into liquid water. The liquid water then enters the water collection tank through the return pipe. After the defogging treatment, the air is discharged after the water droplets are removed by the water collector.
This technology eliminates water vapor outside the cooling tower, reduces humidity, prevents corrosion damage, and extends the equipment's lifespan.

A mist-eliminating cooling tower that enhances heat and mass transfer through water spraying Technical Field
[0001] This utility model relates to the field of cooling tower technology, and in particular to a mist-eliminating cooling tower that enhances heat and mass transfer through water spraying. Background Technology
[0002] A cooling tower is a device that uses the contact between air and water to cool water. It uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere, thereby reducing the temperature inside the tower. In many fields such as industrial production and power energy, cooling towers are key equipment in thermal circulation systems, undertaking the important task of dissipating heat from process fluids into the atmospheric environment, and playing a vital role in ensuring the stable operation of the system and efficient production.
[0003] During operation, traditional cooling towers exchange heat directly with the air, generating a large amount of water vapor. Traditional cooling towers directly discharge the water vapor outside the tower, which increases the humidity in the surrounding area, causing corrosion damage to nearby buildings and equipment and affecting their service life. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-fogging cooling tower that enhances heat and mass transfer through water spraying.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fog-removing cooling tower that enhances heat and mass transfer through water spraying includes a cooling tower body. Cooling water storage tanks are installed on both sides of the upper end of the outer wall of the cooling tower body. A delivery pipe is provided at one end of the cooling water storage tank. The delivery pipe passes through the side wall of the cooling tower body and is located inside the cooling tower body. Several spray heads are installed on the delivery pipe. A baffle is provided inside the cooling tower body, and the baffle is located below the spray heads.
[0007] The partition has a conical groove in the center, several guide grooves at both ends of the top of the partition, and a water collection groove at both ends of the partition. The water collection groove is located at the outer end of the guide groove and is connected to the guide groove.
[0008] Furthermore, a preferred structure is characterized in that a return pipe is fixedly installed on both sides of the partition, the return pipe is embedded in the inner wall of the cooling tower body, and one end of the return pipe is located inside the cooling tower body.
[0009] Furthermore, a preferred structure is characterized in that a water collection pool is provided at the bottom of the cooling tower body, and an output pipe II is installed at one end of the bottom of the cooling tower body, the output pipe II being connected to the water collection pool.
[0010] Furthermore, a preferred structure is characterized in that a circulation pump is installed at the top of the second output pipe, an output pipe is installed at the top of the circulation pump, one end of the first output pipe is embedded in the inner wall of the cooling tower, and a spray system is installed at one end of the first output pipe located inside the cooling tower.
[0011] Furthermore, a preferred structure is characterized in that a packing layer is installed inside the cooling tower body, and the packing layer is located between the water collection tank and the spray system.
[0012] Furthermore, a preferred structure is characterized in that a fan is installed on the top of the cooling tower body.
[0013] Furthermore, a preferred structure is characterized in that a water collector is installed at the top of the cooling tower body, and the water collector is located below the fan and above the spray head.
[0014] The beneficial effects of this utility model are as follows:
[0015] In this invention, a large amount of water vapor generated during the heat exchange process rises, and the spray head sprays out low-temperature cooling water. When the water vapor comes into contact with the low-temperature cooling water, the water vapor will further condense into liquid water. The liquid water enters the water collection tank through the return pipe. After the air is treated to eliminate fog, it passes through the water collector to remove the water droplets it carries, and then is discharged outside the tower by the fan, thereby achieving the purpose of eliminating fog.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Referring to Figures 1-6, a defogging cooling tower that enhances heat and mass transfer through spraying water includes a cooling tower body 1. Cooling water storage tanks 3 are installed on both sides of the upper end of the outer wall of the cooling tower body 1. A conveying pipe 31 is provided at one end of the cooling water storage tank 3. The conveying pipe 31 passes through the side wall of the cooling tower body 1 and is located inside the cooling tower body 1. A plurality of spray nozzles 311 are installed on the conveying pipe 31. A baffle 7 is provided inside the cooling tower body 1, and the baffle 7 is located below the spray nozzles 311.
[0025] The partition 7 has a conical groove 71 in the center, several guide grooves 72 at both ends of the top of the partition 7, and a water collection groove 73 at both ends of the partition 7. The water collection groove 73 is located at the outer end of the guide groove 72 and is connected to the guide groove 72.
[0026] Meanwhile, return pipes 11 are fixedly installed on both sides of the partition 7. The return pipes 11 are embedded in the inner wall of the cooling tower body 1, and one end of the return pipe 11 is located inside the cooling tower body 1. Water in the water vapor enters the water collection pool 101 through the return pipe 11.
[0027] Furthermore, a water collection pool 101 is provided at the bottom of the cooling tower body 1, and an output pipe 8 is installed at one end of the bottom of the cooling tower body 1, which is connected to the water collection pool 101.
[0028] Meanwhile, a circulation pump 5 is installed at the top of the second output pipe 8, and an output pipe 4 is installed at the top of the circulation pump 5. One end of the output pipe 4 is embedded in the inner wall of the cooling tower body 1, and a spray system 9 is installed at the other end of the output pipe 4 inside the cooling tower body 1. The circulation pump 5 draws hot water from the water collection tank 101 into the spray system 9 through the output pipe 4, and then the spray system 9 sprays it out evenly.
[0029] Furthermore, a packing layer 10 is installed inside the cooling tower body 1. The packing layer 10 is located between the water collection tank 101 and the spray system 9. The spray system 9 sprays hot water evenly onto the packing layer 10 to form fine water droplets.
[0030] Meanwhile, a fan 2 is installed on the top of the cooling tower body 1. The fan 2 draws outside air into the tower through the air inlet, and then makes full contact with the small water droplets on the packing layer 10 to exchange heat.
[0031] Furthermore, a water collector 6 is installed at the top inside the cooling tower body 1. The water collector 6 is located below the fan 2 and above the spray head 311. The water collector 6 removes water droplets carried in the air.
[0032] In this embodiment, when the cooling tower is working, the hot water in the water collection tank 101 enters the output pipe 8 through the circulation pump 5, and then enters the spray system 9 through the delivery pipe 4. The nozzles of the spray system 9 spray the hot water evenly, which is evenly sprinkled on the packing layer 10, forming fine water droplets. Outside air enters the tower from the air inlet under the action of the fan 2, and comes into full contact with the water droplets on the packing layer 10 to exchange heat. The temperature of the hot water decreases, the temperature of the air increases, and the humidity increases. The hot and humid air continues to rise after passing through the packing layer 10, and passes through the conical groove 7 on the baffle 7. 1. The low-temperature cooling water in the cooling water storage tank 3 enters the conveying pipe 31 and is sprayed out through the spray head 311. The low-temperature cooling water comes into contact with the hot and humid air, causing the water vapor in the air to condense into liquid water. The condensed liquid water enters the water collection tank 73 through the guide channel 72 on the partition 7. Then, the liquid water enters the return pipe 11 through the water collection tank 73 and is discharged into the water collection pool 101 through the return pipe 11. After the air is treated to remove fog, it passes through the water collector to remove the water droplets it carries and is then discharged outside the tower by the fan, thus completing the purpose of fog removal.
[0033] In this invention, a large amount of water vapor generated during the heat exchange process rises, and the spray head 311 sprays out low-temperature cooling water. When the water vapor comes into contact with the low-temperature cooling water, the water vapor will further condense into liquid water. The liquid water enters the water collection tank 101 through the return pipe 11. After the air is treated to eliminate fog, it passes through the water collector 6 to remove the water droplets it carries, and then is discharged outside the tower by the fan 2, thereby achieving the purpose of eliminating fog.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
