Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a cooling tower with a noise reduction structure. 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 primarily utilizes the heat exchange between water and air to generate steam, which then evaporates and carries away heat, achieving evaporative heat dissipation, convective heat transfer, and radiative heat transfer to dissipate waste heat generated in industrial processes or refrigeration and air conditioning systems, thus lowering the water temperature. Currently, when a cooling tower is in operation, the hot water sprayed from its internal water distribution system passes through the cooling packing material for cooling. The cooled water then falls directly into a collection tank at the bottom of the cooling tower. Due to the height difference between the cooling packing material and the collection tank, the direct impact of the falling water into the collection tank generates continuous low-to-medium frequency noise. This noise propagates outwards from the air inlet at the top of the collection tank, causing noise pollution. Therefore, we propose a cooling tower with a noise reduction structure. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a cooling tower with a noise reduction structure. This invention solves the problem that in current cooling towers, the hot water sprayed from the internal water distribution system passes through the cooling packing material for cooling, and the cooled water falls directly into a collection tank at the bottom of the cooling tower. Because there is a certain height difference between the cooling packing material and the collection tank, the water falling directly into the collection tank generates continuous low-to-medium frequency noise. This noise then propagates outwards from the air inlet mesh on the upper side of the collection tank, causing noise pollution.

[0004] This utility model discloses a cooling tower with a noise reduction structure, comprising a base, a support ring above the base, multiple matrix-arranged air inlets on the support ring, a tower body above the support ring, a mounting frame at the upper center of the tower body, a motor at the upper center of the mounting frame, the motor's rotating shaft passing through the mounting frame and fixedly connected to the fan blades, a water distributor at the upper end of the tower body, packing material below the water distributor, a V-shaped baffle below the packing material inside the tower body, a first sponge above the V-shaped baffle, an annular baffle below the V-shaped baffle, and a second sponge above the annular baffle.

[0005] In the above scheme, both the V-shaped baffle and the annular baffle are provided with multiple guide holes arranged in a matrix.

[0006] In the above scheme, limiting plates are provided on both sides of the lower end of the V-shaped baffle.

[0007] In the above scheme, a pump body is provided at the bottom of the base, and the output end of the pump body is connected to the water distributor through a guide pipe.

[0008] In the above scheme, a protective cover is provided above the tower body on the outside of the motor, and sound-absorbing cotton is provided inside the protective cover.

[0009] In the above scheme, the cross-section of the annular baffle is an inverted cone shape.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a cooling tower with a noise reduction structure. Water droplets fall onto a first sponge and a second sponge, which buffer the gravity of the water and effectively absorb noise during the water droplet process. The water droplets can then fall into the base through the guide holes. The sound-absorbing cotton can absorb the noise generated by the motor during operation, thus effectively preventing noise pollution caused by the motor. This cooling tower has a simple structure, good cooling effect, and effectively reduces noise from the motor and the falling water, significantly improving the practicality of the cooling tower.

A motor 6 is located at the middle of the upper part of the mounting frame 5. The rotating shaft of the motor 6 passes through the mounting frame 5 and is fixedly connected to the fan blades 7. When the motor 6 is working, the motor 6 drives the fan blades 7 to rotate, and the rotating fan blades 7 can drive the airflow inside the tower body 4. The upper part of the tower body 4 is provided with a water distributor 8, and the bottom of the water distributor 8 is provided with packing material 9. The bottom of the tower body 4 is provided with a V-shaped baffle 10, the top of the V-shaped baffle 10 is provided with a first sponge 11, the bottom of the V-shaped baffle 10 is provided with an annular baffle 12, and the top of the annular baffle 12 is provided with a second sponge 13. After passing through the packing material 9, the water falls onto the first sponge 11 and the second sponge 13. The first sponge 11 and the second sponge 13 can buffer the gravity of the water, and at the same time, the first sponge 11 and the second sponge 13 can effectively absorb the noise during the water droplet process.

[0018] Both the V-shaped baffle 10 and the annular baffle 12 are provided with multiple matrix-arranged guide holes 14, so that water that falls on the first sponge 11 and the second sponge 13 can fall into the base 1 through the guide holes 14.

[0019] The V-shaped baffle 10 is provided with limiting plates 15 on both sides of its lower end, which can limit the first sponge 11.

[0020] The bottom of the base 1 is provided with a pump body 16. The output end of the pump body 16 is connected to the water distributor 8 through the guide pipe 17. When the pump body 16 is working, the pump body 16 can draw air from the water inside the base 1. Through the conduction of the guide pipe 17, the water inside the base 1 can enter the water distributor 8.

[0021] A protective cover 18 is provided above the tower body 4 on the outside of the motor 6. The protective cover 18 is provided with sound-absorbing cotton 19. The sound-absorbing cotton 19 can absorb the noise generated by the motor 6 when it is working, thereby effectively avoiding noise pollution caused by the sound generated by the motor 6 when it is working.

[0022] The cross-section of the annular baffle 12 is an inverted cone shape.

[0023] Specifically, in this utility model, when the motor 6 is working, the motor 6 drives the fan blade 7 to rotate. The rotating fan blade 7 can drive the airflow inside the tower body 4. After passing through the packing 9, the water falls onto the first sponge 11 and the second sponge 13. The first sponge 11 and the second sponge 13 can buffer the gravity of the water. At the same time, the first sponge 11 and the second sponge 13 can effectively absorb the noise during the water droplet process. The water that falls onto the first sponge 11 and the second sponge 13 can fall into the base 1 through the guide hole 14. When the pump body 16 is working, the pump body 16 can draw air from the water inside the base 1. Through the conduction of the guide pipe 17, the water inside the base 1 can enter the water distributor 8. The sound-absorbing cotton 19 can absorb the noise generated when the motor 6 is working, thereby effectively avoiding noise pollution caused by the sound generated when the motor 6 is working.
