Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a water vapor recovery device for a cooling tower using a ceramic membrane module. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. It utilizes the principle of heat exchange between water and air to generate steam, which evaporates and carries away heat to achieve evaporative heat dissipation. It also uses principles such as convective heat transfer and radiative heat transfer to dissipate waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system.

[0003] In Chinese Patent Application No. 202322102004.8, this utility model discloses a cooling tower, including a tower cylinder, a fixed cylinder fixedly connected to the center of the upper part of the tower cylinder, a water inlet ring pipe arranged at the upper part of the tower cylinder, and multiple nozzles arranged on the inner side of the outer side of the water inlet ring pipe, all of which face the fixed cylinder. The cooling tower, through the structure of multiple sets of nozzles, air outlet pipes and fixed cylinders, allows hot water to be sprayed directly onto the outer surface of the fixed cylinder, increasing its contact area with the air. Then, the hot air and steam are blown to the top of the tower cylinder and discharged through multiple sets of air valves, thereby improving heat dissipation efficiency by increasing the contact area.

[0004] Existing cooling towers improve heat dissipation efficiency by increasing the contact area through structures such as multiple sets of air valves, air outlet pipes, and fixed cylinders. However, most of these cooling towers adopt an open outlet design, which causes a large amount of water vapor to be directly emitted into the atmosphere. If this water vapor is not recycled in time, it will not only cause serious waste of water resources, but also significantly increase the production costs of enterprises, affecting their economic benefits and sustainable development capabilities.

Finally, the water vapor is condensed into water and transported to the water tank. Attached Figure Description

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] According to the embodiments of this utility model, combined with Figures 1 to 4 The diagram illustrates a water vapor recovery device for a cooling tower using a ceramic membrane module. It includes a cooling component 1 with a recovery component 2 mounted on its upper end. The cooling component 1 comprises a cooling tower body 11, inside which a ceramic membrane module is installed. The ceramic membrane module filters hot air and water vapor, ensuring the cleanliness of the water vapor and hot air discharged from the cooling tower body 11. A fan 15 is mounted on the top of the cooling tower body 11, and a motor 16 is fixedly connected to the outer surface of the upper end of the cooling tower body 11. During subsequent installation, a protection device for the motor 16 can be added according to the actual operating environment to ensure normal operation. A cooling fan 17 is fixedly connected to the output end of the motor 16. The recovery component 2 includes a recovery cover 21, which is fixedly installed on the upper surface of the cooling tower body 11. A cooling plate 22 is fixedly connected inside the recovery cover 21 and positioned above the fan 15. A cooling pipe 23 is installed at the output end of the recovery cover 21, and a dispersing component 24 is installed on the cooling pipe 23. The cooling fan 17 corresponds to the dispersing component 24, and the output end of the cooling pipe 23 extends into a water tank 25.

[0028] When installing the cooling device, a set of water pipes connects the water tank 25 and the cooling plate 22, and a set of water pumps is installed on this section of water pipes to facilitate the subsequent transportation of condensate from the water tank 25 to the cooling plate 22, providing circulating water for the cooling plate 22. When the cooling tower body 11 is used for cooling operations, a large amount of hot air and water vapor are generated during the cooling process. Under the action of the fan 15, the hot air and water vapor are discharged from the top of the cooling tower body 11. The discharged hot air and water vapor enter the recovery hood 21. Then, under the action of the cooling plate 22, some of the water vapor is cooled and liquefied. The liquefied condensate drips into the cooling tower body 11. The remaining water vapor and hot air will pass through the cooling plate 22 and rise to the top of the recovery hood 21, and then enter the cooling pipe 23 to move towards the water tank 25. During the movement, the cooling fan 17 and the dispersing component 24 work together to cool the water vapor, so that the remaining water vapor is also cooled and liquefied during the movement, and finally flows into the water tank 25 for storage.

[0029] According to the embodiments of this utility model, combined with Figure 1 , Figure 2 and Figure 4The diagram shows a water vapor recovery device for a cooling tower with a ceramic membrane module. A water inlet pipe 12 is installed at the upper end of the cooling tower body 11, and the water inlet pipe 12 is connected to a spray pipe inside the cooling tower body 11. Multiple sets of nozzles are installed at the output end of the spray pipe to discharge the liquid requiring cooling from the spray pipe. An air supply pipe 13 is installed below the water inlet pipe 12, and the air supply pipe 13 is connected to an exhaust pipe inside the cooling tower body 11. A valve and an exhaust port are installed on the exhaust pipe to discharge the cooled gas from the exhaust pipe, allowing the cooled air to contact the hot water and complete the cooling operation. A drain pipe 14 is connected to the output end of the cooling tower body 11, and a valve is installed on the drain pipe 14. A pulley A151 is fixedly connected to the upper end of a fan 15, and a pulley B161 is fixedly connected to the output end of a motor 16. A belt 162 is fitted onto pulleys A151 and B161. A through groove 211 is opened on the recovery cover 21, and the through groove 211 corresponds to the belt 162.

[0030] The liquid that needs to be cooled and the gas used to cool the liquid are transported to the spray pipe and the exhaust pipe through the water inlet pipe 12 and the gas supply pipe 13, so as to achieve the cooling operation of the liquid. The cooled liquid is discharged from the cooling tower body 11 through the drain pipe 14. Because of the pulleys A151, B161 and belt 162, the motor 16 can also drive the fan 15 to rotate, so as to remove the water vapor and hot air in the cooling tower body 11. Because of the through slot 211, the belt 162 is not affected by the recovery hood 21 when it is performing the transmission operation.

[0031] According to the embodiments of this utility model, combined with Figures 3 to 6 The diagram shows a water vapor recovery device for a cooling tower with a ceramic membrane module. The cooling plate 22 has multiple sets of through holes 221. A water channel 222 is provided inside the cooling plate 22. The output end of the cooling plate 22 is connected to the water channel 222. The dispersing component 24 includes a connecting pipe 241. Two sets of connecting pipes 241 are provided. Multiple sets of dispersing pipes 242 are installed between the two sets of connecting pipes 241. The two sets of connecting pipes 241 are connected to the cooling pipe 23. The cooling fan 17 is located below the dispersing pipes 242.

[0032] After circulating water is pumped into the cooling plate 22 by water pump and water pipe, the cooling water fills the water passage 222 and cools the cooling plate 22. The cooling water is finally discharged from the output end of the cooling plate 22 and flows into the cooling tower body 11. Hot air and water vapor pass through the cooling plate 22 through the through hole 221. During the contact process, the water vapor is cooled and liquefied, thus recovering some of the water vapor. In addition, the heat dissipation area of ​​the cooling pipe 23 is indirectly increased by the setting of the connecting pipe 241 and the dispersing pipe 242. Then, the subsequent water vapor is recovered through the cooling pipe 23.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
