Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and in particular to a low-noise cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus achieving heat dissipation through evaporation, convection, and radiation. This process dissipates 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. The device is generally cylindrical, hence the name cooling tower.

[0003] Although the existing cooling towers are equipped with packing material that has a certain noise reduction effect, the dripping noise is still generated when the water falls through the packing material into the water storage tank below.

[0004] Therefore, a low-noise cooling tower is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a low-noise cooling tower to solve the above-mentioned problems. Although existing cooling towers are equipped with packing material to reduce the noise when water falls, the water still generates a certain degree of noise when it flows through the packing material into the storage tank.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a low-noise cooling tower, comprising: a cooling tower body and a fan disposed above it, wherein the cooling tower body is provided with filler in the middle part;

[0007] A noise reduction component is disposed in the lower middle part of the cooling tower body and below the packing material;

[0008] The noise reduction component includes a surrounding tube disposed below the filler, and a guide rod is disposed inside the surrounding tube and located at the axis.

[0009] Preferably, the noise reduction component further includes a guide plate disposed below the packing and fixed to the inner wall of the cooling tower body. The guide plate has an inverted flat-topped conical design, and the surface of the guide plate has multiple openings. By setting the guide plate, the water falling through the packing can be received and gathered to prevent the water from falling on its own.

[0010] Preferably, the upper end of the surrounding pipe is designed as an inverted cone, and the upper end of the surrounding pipe is connected to the inlet. Through the above design, the water source can be guided towards the guide rod.

[0011] Preferably, the enclosing tube is provided with corner strips inside. Multiple corner strips are arranged in a circular array with the axis of the enclosing tube as the axis point. By setting the corner strips, the water source in the enclosing tube can be evenly distributed, improving the smoothness of the water flow, and at the same time ensuring that the water source does not fall off the guide.

[0012] Preferably, the surface of the guide rod is provided with a buffer plate. The buffer plate is tapered and arranged in a rectangular array of several buffer plates. By setting the buffer plate, the water flow can be continuously buffered by the multi-stage buffer plate as the water flows down the guide rod, thereby slowing down the falling speed of the water flow and greatly reducing the noise generated when the water flows into the water.

[0013] Preferably, a water storage tank is provided at the lower inner part of the cooling tower body, and the lower ends of the guide rod and the surrounding pipe extend into the water storage tank. Through the above design, the problem of noise caused by the distance between the water source flowing out from the lower end of the guide rod and the surrounding pipe and the water source in the water storage tank can be avoided.

[0014] Preferably, a spray pipe is provided above the filler. The spray pipe has a disc-shaped design and is on the same axis as the filler. By setting the spray pipe on the same axis as the filler, the uniformity of water spraying can be maintained.

[0015] The beneficial effects of this utility model are:

[0016] By setting the guide rod of the noise reduction component, the water flow through the filler can be vertically guided, so that the water flow can smoothly enter the water storage tank. At the same time, the surface of the guide rod is also equipped with a surrounding pipe, which can surround the water source when the water flow is too large, and can also achieve a secondary guiding effect, which can prevent the water flow from leaving the guide and reduce the noise generated when the water flows in.

[0017] By setting bends on the inner wall of the enclosing pipe, the water source in contact with the enclosing pipe can be dispersed and guided vertically, which can ensure the uniformity of the water flow and reduce the problem of water accumulation causing it to deviate from the guide. At the same time, by setting buffer plates on the surface of the guide rod, the water flow can be continuously buffered by the multi-stage buffer plates as it flows down the guide rod, which can slow down the falling speed of the water flow and greatly reduce the noise generated when the water flows in.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, a low-noise cooling tower includes: a cooling tower body 1 and a fan 2 disposed inside and above it, and packing 3 is disposed in the middle of the cooling tower body 1.

[0025] The working principle of the cooling tower is as follows: First, hot water flows into the cooling tower from the system, and then enters the interior of the spray pipe 4 through the pipe. The spray pipe 4 will spray the hot water downward and distribute it on the packing 3 inside the tower. At this time, the fan 2 is turned on, and the fan 2 drives the air to flow. Water and air come into contact here, and the water will partially evaporate, taking away heat and thus lowering the water temperature.

[0026] Noise reduction component 6 is located in the lower middle part of the cooling tower body 1 and below the packing 3;

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the noise reduction component 6 includes a surrounding tube 602 disposed below the packing 3, and a guide rod 604 disposed inside the surrounding tube 602 and located at the axis; the noise reduction component 6 also includes a guide plate 601 disposed below the packing 3 and fixed to the inner wall of the cooling tower body 1, the guide plate 601 having an inverted flat-topped conical design, and multiple openings on the surface of the guide plate 601; a buffer plate 605 is disposed on the surface of the guide rod 604, the buffer plate 605 having a conical design, and several buffer plates 605 are arranged in a rectangular array;

[0028] When the water source passes through the filler 3 and falls, it first falls into the interior of the guide plate 601 and is gathered. Then the water source enters the opening and flows into the surrounding pipe 602. If the water source is small, the water source will flow downward along the guide rod 604. When the water source contacts the guide rod 604, since the guide rod 604 is designed vertically and has a buffer plate 605 on its surface, the falling water source will continue to contact the buffer plate 605. The buffer plate 605 will slow down the falling speed of the water source until the water source flows to the lower end of the guide rod 604 and enters the water storage tank 5. At that time, the water source will slowly merge with the water source in the water storage tank 5.

[0029] It should be noted that the buffer sheet 605 is made of rubber. The rubber body has a certain degree of elasticity. The rubber material can not only effectively absorb the impact of water droplets and water flow and reduce the noise generated by the impact, but also gradually slow down the impact of the water flow at the speed of the water flow, reduce the instantaneous impact force when the water droplets come into contact with the surface, and help reduce the disturbance of the water flow, making it flow more smoothly downwards.

[0030] The upper end of the surrounding tube 602 is designed as an inverted cone, and the upper end of the surrounding tube 602 is connected to the through port; the inside of the surrounding tube 602 is provided with corner bars 603, and multiple corner bars 603 are arranged in a ring array with the axis of the surrounding tube 602 as the axis point.

[0031] When the water flow is too large, the water will flow downwards along the surrounding pipe 602 and the guide rod 604 at the same time. At this time, the water flow inside the surrounding pipe 602 will be evenly dispersed by the multiple bends 603 of the surrounding pipe 602 and guided vertically downwards, which can effectively reduce the noise generated when the water source enters the water source.

[0032] A water storage tank 5 is provided at the lower inner part of the cooling tower body 1, and the lower ends of the guide rod 604 and the surrounding pipe 602 extend into the water storage tank 5.

[0033] It should be noted that the lower ends of both the guide rod 604 and the surrounding pipe 602 are in contact with the water source in the reservoir 5. This allows the water source to merge with the water source in the reservoir 5 more quickly and smoothly as it comes into contact with the water source along the guide rod 604 and the surrounding pipe 602, reducing water source fluctuations. It also avoids the problem of noise caused by the distance between the water source flowing out from the lower ends of the guide rod 604 and the surrounding pipe 602 and the water source in the reservoir 5.

[0034] A nozzle 4 is provided above the packing 3. The nozzle 4 is a disc-shaped design and is on the same axis as the packing 3.

[0035] Working principle: When water flows through the filler 3 and falls, it first falls into the guide plate 601 and is gathered. Then, the water enters the inlet and flows into the surrounding pipe 602. If the water is small, it will flow downward along the guide rod 604. When the water comes into contact with the guide rod 604, the guide rod 604 is vertically designed and has a buffer plate 605 on its surface. Therefore, the falling water will continue to contact the buffer plate 605, which will slow down the falling speed of the water until it flows to the lower end of the guide rod 604 and enters the water storage tank 5. At this time, the water will slowly merge with the water in the water storage tank 5. When the water flow is too large, the water will flow downward along the surrounding pipe 602 and the guide rod 604 at the same time. At this time, the water flow inside the surrounding pipe 602 will be evenly dispersed by the multiple bends 603 of the surrounding pipe 602 and guided vertically downward, which can effectively reduce the noise generated when the water enters.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
