Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a noise-reducing circulating water cooling tower. Background Technology

[0002] A cooling tower is a device that cools water, in which the water exchanges heat and mass with the flowing air, causing the water temperature to drop; it is widely used in air conditioning circulating water systems and industrial circulating water systems.

[0003] During the cooling process, after being sprayed, the high-temperature water needs to pass through the packing layer and drip to the bottom of the tower. Since the space between the packing layer and the bottom of the tower needs to provide for the flow of cold air, the height between the packing layer and the bottom of the tower is relatively high, which causes the water droplets to generate noise. Therefore, a noise-reducing circulating water cooling tower that can reduce this noise is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a noise-reducing circulating water cooling tower.

[0005] The technical solution of this utility model is: a noise-reducing circulating water cooling tower, including a tower body, an air outlet pipe, a spray pipe, an air inlet pipe and a drain pipe arranged sequentially from top to bottom on the tower body, and a packing layer and water-absorbing cotton arranged sequentially from top to bottom inside the tower body. The water-absorbing cotton is slidably connected to the inner wall of the tower body with sealing between the upper and lower parts. A limiting mesh plate is provided inside the tower body below the water-absorbing cotton. A scraper is embedded in the inner wall of the tower body for squeezing the water-absorbing cotton to remove water in cooperation with the limiting mesh plate. The water-absorbing cotton is connected to the limiting mesh plate by a spring.

[0006] Furthermore, a cleaning plate is embedded in the inner wall of the tower body, which cleans the bottom of the packing layer by sliding the absorbent cotton up and down. A first airbag and a spring are arranged longitudinally between the absorbent cotton and the limiting mesh plate. The cleaning plate is connected to the first airbag through a second airbag and a first pipe embedded in the side wall of the tower body.

[0007] Explanation: The first and second airbags are driven to extend and retract by the downward pressure of the absorbent cotton after absorbing water and the upward movement of the spring after dehydration, so that the cleaning plate can intermittently clean the water droplets at the bottom of the filler layer.

[0008] Furthermore, the scraper consists of a rotating rod and a cam sleeved on the rotating rod, and the inner wall of the tower body is provided with friction blocks for rotating the rotating rod when it extends and retracts.

[0009] Note: Before the scraper is driven, the scraper is embedded in the inner wall of the tower and will not affect the up and down sliding of the absorbent cotton. After the scraper is driven, the cam rotates and the protruding part can squeeze and dehydrate the absorbent cotton.

[0010] Furthermore, the tower body is equipped with a transparent acrylic plate for observing the state of the absorbent cotton.

[0011] Note: After long-term use, dirt on the surface of the absorbent cotton will affect its absorbency. Staff can replace the absorbent cotton after observing the dirt through a transparent acrylic plate.

[0012] Furthermore, the inner walls of the tower body sidewalls, air outlet pipes, and air inlet pipes are all equipped with porous sound-absorbing panels.

[0013] Description: Sound absorption and noise reduction are achieved by using porous sound-absorbing panels to absorb sound from the entire tower structure.

[0014] Furthermore, a solid sound-absorbing panel is provided inside the side wall of the air inlet pipe. Between the solid sound-absorbing panel and the porous sound-absorbing panel, there are multiple cleaning rods for cleaning the porous sound-absorbing panel through the holes. The cleaning rods are connected to the first airbag through the third airbag and the second pipe embedded inside the side wall of the tower.

[0015] Explanation: The up-and-down sliding of the absorbent cotton causes the third airbag to reciprocate and extend the cleaning rod, thereby cleaning the holes, extending the service life of the porous sound-absorbing panel, and thus improving the noise reduction effect.

[0016] The beneficial effects of this utility model of circulating water cooling tower are:

[0017] (1) The circulating water cooling tower of this utility model reduces the noise generated by water falling from the packing layer to the bottom of the tower by setting water-absorbing cotton and limiting mesh between the packing layer and the bottom of the tower body. The water-absorbing cotton is intermittently squeezed and dehydrated by the scraper. The water-absorbing cotton will slide up and down repeatedly due to water absorption and dehydration. The water remaining at the bottom of the packing layer is cleaned by the up and down sliding, which reduces noise and improves the cooling effect of high temperature water.

[0018] (2) The circulating water cooling tower of this utility model improves the noise reduction effect by setting a porous sound-absorbing plate in the inner wall of the air inlet pipe and other positions, and uses the up and down sliding of the water-absorbing cotton to clean the holes of the porous sound-absorbing plate, thereby improving the service life of the porous sound-absorbing plate and further improving the noise reduction effect.

Detailed Implementation

[0026] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0027] Example 1

[0028] A noise-reducing circulating water cooling tower, such as Figure 1 and Figure 2 As shown, the structure includes a tower body 1, an air outlet pipe 12, a spray pipe 13, an air inlet pipe 11, and a drain pipe 15 arranged sequentially from top to bottom on the tower body 1, and a packing layer 14 and absorbent cotton 2 arranged sequentially from top to bottom inside the tower body 1. The absorbent cotton 2 is located below the air inlet pipe 11. The absorbent cotton 2 is slidably and sealed to the inner wall of the tower body 1. A limiting mesh plate 22 is provided inside the tower body 1 below the absorbent cotton 2. A scraper 25 is embedded in the inner wall of the tower body 1 to cooperate with the limiting mesh plate 22 to squeeze the absorbent cotton 2 to remove water. The absorbent cotton 2 is connected to the limiting mesh plate 22 by a spring 24. It can be understood that the spray nozzle of the spray pipe 13 is far from the packing layer. The distance 14 is 1 / 8 of the distance between the packing layer 14 and the bottom of the tower body 1, so the sound of the spray water from the spray pipe 13 contacting the packing layer 14 is smaller; the packing layer 14 is made of PVC material, and the absorbent cotton 2 is made of polyurethane material. The absorbent cotton 2 has a rigid frame to prevent deformation during sliding and squeezing, and the rigid frame is sealed and slidably connected to the inner wall of the tower body 1; it can be understood that the absorbent cotton 2 remains level on all four sides during the process of moving down due to gravity and resetting due to the spring 24, and all four sides are sealed and slidably connected to the inner wall, so that there will be no situation where one side is tilted due to uneven force;

[0029] like Figure 2As shown, a cleaning plate 21 is embedded in the inner wall of the tower body 1, which cleans the bottom of the packing layer 14 by sliding the absorbent cotton 2 up and down. A first airbag 23 and a spring 24 are arranged longitudinally between the absorbent cotton 2 and the limiting mesh plate 22. The cleaning plate 21 is connected to the first airbag 23 through a second airbag 211 and a first pipe embedded in the side wall of the tower body 1.

[0030] like Figure 3 As shown, the scraper 25 consists of a rotating rod 252 and a cam 251 sleeved on the rotating rod 252. The inner wall of the tower body 1 is provided with a friction block 253 for rotating the rotating rod 252 when it extends and retracts. An electric telescopic rod for driving the scraper 25 to move back and forth is embedded in the side wall of the tower body 1, as well as a contact sensor and controller set on the limiting mesh plate 22 for sensing the downward movement of the absorbent cotton 2. The contact sensor, the electric telescopic rod 251 and the controller are all electrically connected, and the contact sensor, the electric telescopic rod and the controller are all commercially available devices.

[0031] The working principle of the noise-reducing circulating water cooling tower described above is as follows: High-temperature water is sprayed onto the packing layer 14 through the spray pipe 13. Cold air enters the tower body 1 from the air inlet pipe 11, passes through the packing layer 14, and comes into contact with the high-temperature water to cool it. The cooling water drips onto the absorbent cotton 2 and is absorbed, reducing the noise of the cooling water falling directly onto the bottom of the tower body 1. As the absorbent cotton 2 continues to absorb water, its gravity increases and it moves downward, compressing the first airbag 23 and the spring 24, causing the second airbag 211 to drive the cleaning plate 21 to extend and reach the packing layer 1. 3. Clean the bottom. When the absorbent cotton 2 moves down to the lowest point, the contact sensor drives the electric telescopic rod to make the scraper 25 squeeze the absorbent cotton 2 to remove water. When the scraper 25 moves outward, the rotating rod 252 rotates after passing the friction block 253, thereby rotating the horizontal cam 251 to the vertical position, thus squeezing the absorbent cotton 2. After the scraper 25 is retracted, the weight of the absorbent cotton 2 is reduced and it resumes to move upward under the action of the spring 24. The water squeezed out by the absorbent cotton 2 is discharged through the limiting mesh plate 22 and the drain pipe 15.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that, Figure 4 As shown, the absorbent cotton 2 is detachably connected to the inner wall of the tower body 1, and the tower body 1 is provided with a transparent acrylic plate 16 for observing the state of the absorbent cotton 2.

[0034] The working principle of this embodiment differs from that of embodiment 1 in that, after long-term cooling, impurities carried by high-temperature water will remain on the surface of the absorbent cotton 2, reducing its water absorption effect. When the staff observes that the surface of the absorbent cotton 2 is dirty, they replace the absorbent cotton 2.

[0035] Example 3

[0036] The difference between this embodiment and embodiment 2 is that, Figure 5 and Figure 6 As shown, the inner walls of the tower body 1, the air outlet duct 12, and the air inlet duct 11 are all provided with porous sound-absorbing panels 111. The inner wall of the air inlet duct 11 is provided with a solid sound-absorbing panel 114. The porous sound-absorbing panel 111 is made of mineral wool board, and the solid sound-absorbing panel 114 is made of rock wool. There are multiple cleaning rods 112 between the solid sound-absorbing panel 114 and the porous sound-absorbing panel 111 for cleaning the porous sound-absorbing panel 111 through the holes. The cleaning rods 112 are connected to the first air bag 23 through the third air bag 113 and the second pipe buried inside the side wall of the tower body 1.

[0037] The working principle of this embodiment differs from that of embodiment 2 in that when the absorbent cotton 2 moves up and down, it simultaneously drives the third airbag 113 to drive the cleaning rod 112 to clean the holes of the porous sound-absorbing plate 111, thereby improving the sound absorption effect.
