Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a low-noise and high-efficiency heat exchange cooling tower. Background Art

[0002] At present, most existing cooling tower systems use open water cooling, including a cooling tower body, a water collection tank at the bottom of the cooling tower, and a circulating water pump to pump water from the water collection tank into a heat exchanger. After heat exchange, the circulating water is ejected from the top of the cooling tower through a pipe, and enters the water collection tank after being cooled by a fan. The noise characteristics of this cooling tower system are: a wide noise frequency band, strong low-frequency energy, and the cooling tower has heat dissipation and ventilation requirements when working, and it cannot be completely sealed, so there is a lot of noise pollution to the surrounding environment.

[0003] A patent CN116952010A is disclosed in the prior art. The solution includes setting a guide plate between the noise reduction wall and the cooling tower group, and setting an arc-shaped wind guide edge at the edge of the cooling tower group; the height of the noise reduction wall is less than the height of the air inlet of the cooling tower group, and a plurality of noise reduction wall vents are opened on the noise reduction wall, so that the wind passes through the upper part of the noise reduction wall and the vents and then passes through the guide plate to reach the tower group, which solves the problem that the noise reduction wall is too close to the cooling tower and the height of the noise reduction wall is too high, resulting in a greatly reduced air intake of the cooling tower; by optimizing the noise reduction wall structure, improving the air flow at the cooling tower inlet, and controlling the lateral vortex of the four cooling towers in the corner of the tower group, the noise reduction requirements are met without affecting the cooling efficiency of the cooling tower.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] First, when water droplets fall into the water collection pool, they have great kinetic energy and will generate great noise, which will seriously affect the surrounding environment and cause certain troubles to people's production and life. In addition, the circulating water falls directly into the pool after passing through the filler for heat exchange. Sometimes the circulating water coming out of the filler will converge into a stream, and will basically not cool down again when passing through the middle area between the filler and the pool. After converging into the pool, the circulating water temperature is still high, even worse in summer.

[0006] Secondly, in addition, in the process of circulating water being sprayed from the source through the water distribution pipeline to the filler for heat exchange, it is inevitable that some impurities will be carried with it, gathered in the water pool and sent to the next equipment, which may easily cause blockage of the pipeline and equipment.

[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the defects in the prior art, the utility model provides a low-noise and high-efficiency heat exchange cooling tower to solve the problem that in the traditional technology, when water droplets in the cooling tower drip into the water collection pool, they have great kinetic energy, which will generate great noise and seriously affect the surrounding environment; and the circulating water will inevitably carry some impurities in the process of being sprayed from the source through the water distribution pipeline to the filler for heat exchange, which will gather in the water pool and be sent to the next equipment, which may easily cause blockage of the pipeline and equipment.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A low-noise and high-efficiency heat exchange cooling tower comprises a tower body, wherein the tower body is provided with a water collecting tank and fillers from bottom to top, and a region of the tower body between the water collecting tank and the fillers is provided with a plurality of rotatably arranged noise reduction heat exchange fins in parallel in the horizontal direction.

[0011] As an optimized solution, the noise reduction and heat exchange paddle includes a fan blade, and the relative outer walls of the fan blade are covered with a sound-absorbing gasket.

[0012] As an optimized solution, a plurality of rotating shafts are arranged in parallel on the inner wall of the cooling tower, and the noise reduction and heat exchange paddles are rotatably arranged around the rotating shafts.

[0013] As an optimized solution, a sleeve is rotatably mounted on the rotating shaft, and the inner end of the noise reduction and heat exchange paddle is fixedly connected to the outer wall of the sleeve.

[0014] As an optimized solution, three noise reduction and heat exchange fins are evenly distributed along the circumference on each sleeve.

[0015] As an optimized solution, the fan blade is an arc-shaped plate, and the sound-absorbing gasket is fitted therewith.

[0016] As an optimized solution, slag collecting grooves are evenly distributed on the outer wall of the noise-reducing gasket.

[0017] As an optimized solution, the sound-absorbing gasket is felt or mesh filler.

[0018] As an optimized solution, the fan blades are plastic arc-shaped plates.

[0019] As an optimized solution, the sleeve is a plastic cylinder.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The falling circulating water drives the sleeve to rotate, and the fan blades connected to the sleeve rotate at the same time, which provides a transition area for the water flow, reducing the water spraying noise to a certain extent. On the other hand, the wind brought by the rotation of the fan blades increases the residence time of the circulating water in the air, which can cool the circulating water again.

[0022] The slag collecting groove structure on the surface of the silencer gasket can also filter particulate impurities in the water, reducing the clogging effect on subsequent equipment. BRIEF DESCRIPTION OF THE DRAWINGS
