Description

Technical Field

[0001] This utility model relates to a noise reduction device for cooling tower spray water. Background Technology

[0002] The function of a cooling tower is to exchange heat between high-temperature circulating water and air inside the tower, so that waste heat is transferred to the air and dissipated into the atmosphere. The high-temperature circulating water is evenly sprayed onto the surface of the packing material through the water distribution system, forming a water film or water droplets. After the water temperature is reduced, it falls into the water pool at the bottom of the cooling tower and generates noise by colliding with the water in the pool. This noise is high-frequency noise and can cause disturbance to residents. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a noise reduction device for cooling tower spray water.

[0004] The above objectives are achieved through the following scheme:

[0005] A noise reduction device for cooling tower spray water includes: a cooling tower, a spray water buffer frame placed at the bottom of the cooling tower, the spray water buffer frame including an upper buffer plate, a lower buffer plate and a float, the upper buffer plate and the lower buffer plate being connected and fixed by multiple columns, and two rings of support legs fixed at the bottom of the lower buffer plate, the bottom of the support legs being fixed on the float.

[0006] The lower buffer plate has a water collection hole in the middle and is connected to a water inlet pipe.

[0007] The cooling tower spray water noise reduction device includes an upper buffer plate comprising an upper plastic plate, an upper inner conical rubber plate bonded to the upper plastic plate, and multiple evenly arranged water distribution holes on the upper buffer plate.

[0008] The cooling tower spray water noise reduction device includes a lower buffer plate comprising a lower plastic plate, on which a lower inner cone rubber plate is bonded. Beneficial effects

[0009] 1. By setting an upper buffer plate, the sprayed water will fall onto the upper buffer plate after passing through the filler and be buffered, reducing the height difference of the sprayed water. At the same time, the upper part of the upper buffer plate is a rubber plate, which can effectively reduce the vibration noise caused by water splashing.

[0010] 2. By setting a lower buffer plate, the spray water that has been buffered by the upper buffer plate will fall to the lower buffer plate for further buffering. After being buffered, it will flow along the lower buffer plate towards the center and then flow out through the water pipe to the vicinity of the water surface in the pool. This can effectively reduce the noise generated by the falling spray water.

[0011] 3. This utility model is equipped with a float, so the device will float on the surface of the water in the pool. The spray water flows directly to the water surface after flowing out through the water pipe, which can prevent the spray water from hitting the water surface. Attached Figure Description

Detailed Implementation

[0020] Reference Figures 1 to 5 The present invention relates to a noise reduction device for a cooling tower spray water, comprising: a cooling tower 1, a spray water buffer frame 2 placed at the bottom of the cooling tower, the spray water buffer frame including an upper buffer plate 21, a lower buffer plate 24 and a float 27, the upper buffer plate and the lower buffer plate being connected and fixed by multiple columns 28, and two rings of support legs 26 fixed at the bottom of the lower buffer plate, the bottom of the support legs being fixed on the float.

[0021] The upper buffer plate includes an upper plastic plate 212, an upper inner conical rubber plate 211 is bonded to the upper plastic plate, and a plurality of evenly arranged water distribution holes 22 are provided on the upper buffer plate.

[0022] The lower buffer plate has a water collection hole 23 in the middle and is connected to the water inlet pipe 25;

[0023] The lower buffer plate includes a lower plastic plate 242, on which a lower inner cone rubber plate 241 is bonded. The float is a hollow plastic cylinder with a water flow hole 29 on its side. By setting the water flow hole, the spray water flowing out through the water pipe will fall to the water surface.

[0024] Reference Figures 6-7 This device is placed on the water tank of the cooling tower 1 and floats on the water surface 3. After being sprayed, the water flows through the packing material and falls, landing on the upper buffer plate for cushioning, reducing the height difference of the falling water. The upper part of the upper buffer plate is a rubber plate, which effectively reduces vibration and noise caused by splashing water. The upper inner conical rubber plate is cone-shaped, allowing the water falling onto the upper buffer plate to fall along multiple water distribution holes. Water that doesn't fall quickly enough flows to the middle of the upper inner conical rubber plate and falls through the central water distribution holes, preventing... After the spray water falls onto the upper buffer plate, it flows out from outside the upper buffer plate. After passing through the upper buffer plate, the spray water falls through the water distribution hole onto the lower buffer plate for further buffering. After buffering, it flows along the lower buffer plate towards the center and flows out through the water inlet pipe to the water surface at point 3 in the pool. This can effectively reduce the noise generated by the spray water falling. The device floats on the water surface through the float, and the bottom of the water inlet pipe is above the water surface, close to the water surface. In this way, the spray water falls onto the water surface after flowing out through the water inlet pipe, which can greatly reduce the height difference of the spray water falling and help reduce noise.
