Description

Technical Field

[0001] The utility model relates to the field of cooling towers, in particular to a water distribution nozzle for cooling towers. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to reduce the water temperature. Its working principle is to use the heat exchange between water and air to produce steam, which evaporates and takes away the heat. It dissipates the waste heat generated in industry or refrigeration and air conditioning through the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer, thereby reducing the water temperature and ensuring the normal operation of the system.

[0003] The water sprayed out of the cooling tower is sprayed out by the nozzle inside it. The function of the nozzle is to disperse the water into fine mist so that the water can fully contact with the air, so that the hot air can be discharged from the cooling tower under the drive of the fan, thereby achieving the effect of cooling. When the cooling tower nozzle is working, the circulating cooling water with a certain pressure enters the cooling tower through the water inlet pipe. Under the swirl spray of the nozzle, the water is atomized into fine droplets and sprayed toward the top of the tower. These droplets are fully in contact with the air, accelerating the evaporation of water, thereby improving the cooling effect.

[0004] However, when using traditional nozzles, the water flow directly hits the baffle, which will cause fatigue of the nozzle material after long-term operation, and then damage. The service life is short and it is easy to be damaged. When damaged, it will instantly lose its working ability, causing the entire production line to be affected.

[0005] Therefore, it is necessary to propose a water distribution nozzle for cooling tower to solve the above problems. Utility Model Content

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model provides a first dispersing component and a second dispersing component, so that the water flow in the vertical direction can be decomposed into a rotating force, reducing the direct impact of the water flow on the baffle, preventing the excessive water pressure from causing material fatigue and thus causing damage to the device, and dividing the water flow into two parts for unloading. At the same time, the rotational force brought by the unloading force can also be used to drive the water flow to spray around, thereby improving the dispersing effect of the device on the water flow and reducing the possibility of generating umbrella film;

[0017] 2. Both the first dispersing component and the second dispersing component in the utility model have the function of dispersing water flow, so when one of them is damaged, the device as a whole will not completely lose its working ability, and can still disperse, giving the staff a certain amount of response time, thus avoiding the situation where the production line is shut down due to nozzle damage;

[0018] 3. The utility model can change the size of the guide pipe according to the actual liquid being transported by setting the guide pipe. If a higher flow rate is required, a smaller-diameter guide pipe can be replaced. If there are suspended matter or other debris in the liquid that can easily cause clogging of the device, replacing the guide pipe with a larger diameter can reduce the possibility of the device being blocked, so that the device can work more stably and improve practicality. When the nozzle is damaged and worn after being used for a long time, only the guide pipe needs to be replaced, and there is no need to replace the entire nozzle, thereby reducing operation and maintenance costs.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-Figure 5 A water distribution nozzle for a cooling tower shown in the figure includes a first dispersing component 3 and a second dispersing component 4, the first dispersing component 3 and the second dispersing component 4 are located on the same axis, and the first dispersing component 3 is located above the second dispersing component 4, a mounting head 1 is provided on the side of the first dispersing component 3 away from the second dispersing component 4, a threaded connecting pipe 11 is fixedly installed on the top of the mounting head 1, a guide pipe 5 is provided on the internal sliding card of the threaded connecting pipe 11, a step is provided inside the mounting head 1 for supporting the guide pipe 5, and three support arms 2 distributed in a ring are fixedly installed on the outer ring of the mounting head 1.

[0027] During actual use, the threaded connecting pipe 11 is installed with the outlet pipe of the cooling tower through threads, and the water flow will pass through the guiding pipe 5 and impact on the first dispersing component 3, wherein a part of the water flow will pass through the first dispersing component 3 and impact on the second dispersing component 4. When the water flow impacts the first dispersing component 3, a part of the force will be relieved and dispersed to the surroundings, and the remaining water flow will be blocked by the second dispersing component 4 and dispersed to the surroundings, so as to prevent the water flow speed and pressure from being too high and directly impacting the plate, causing a reduction in life or even damage.

[0028] In the actual production process, there are multiple guide pipes 5, and the inner diameter of each guide pipe 5 is different, which can be changed according to the actual liquid being transported. If a higher flow rate is required, a smaller-diameter guide pipe 5 can be replaced. If there are suspended matter or other debris in the liquid that can easily cause blockage of the device, replacing the guide pipe 5 with a larger diameter can reduce the possibility of the device being blocked, so that the device can work more stably and improve practicality. When the nozzle is damaged and worn due to long-term use, only the guide pipe 5 needs to be replaced, and there is no need to replace the entire nozzle, thereby reducing operation and maintenance costs.

[0029] The three support arms 2 form an equilateral triangle. The structure of the equilateral triangle is very stable and can increase the overall life of the device. A central support ring 22 and a central support plate 24 are provided at the center of the equilateral triangle. The central support ring 22 is used to support the weight of the first dispersing component 3, and the central support plate 24 is used to support the weight of the second dispersing component 4. The central support ring 22 is located in the middle of the support arm 2, and the central support plate 24 is located at the bottom of the support arm 2. The outer circle of the central support ring 22 is fixedly installed in the middle of the corresponding support arm 2 through a plurality of support rods 21. The bottom ends of the three support arms 2 are all fixedly installed on the side surface of the central support plate 24. A first central axis 23 is rotatably installed in the middle of the central support ring 22, and the first central axis 23 is used to provide rotation of the first dispersing component 3. A second central axis 25 is rotatably installed in the middle of the central support plate 24, and the second central axis 25 is used to provide rotation of the second dispersing component 4.

[0030] The first dispersing component 3 includes a first support plate 31, which is in the shape of a conical plate. A first blade 33 is fixedly installed on the upper surface of the first support plate 31. The first blade 33 is composed of a plurality of evenly distributed blades, and the blades are inclined. A first cone 34 is fixedly installed in the middle of the first blade 33. The first central axis 23 is fixedly installed in the middle of the lower surface of the first cone 34. A plurality of groups of annularly distributed scattering plates 35 are fixedly installed on the outer ring of the upper surface of the first support plate 31. Each group of scattering plates 35 is composed of two plates, one large and one small. A central leakage groove 32 is opened in the middle of the first support plate 31.

[0031] When the high-speed water flow hits the first blade 33, the first blade 33 rotates under the impact of the water flow. On the one hand, the vertical impact brought by the water flow can be decomposed into a rotational force and a vertical force, thereby reducing the impact of the high-speed water flow on the baffle. In addition, the water flow impacting the first dispersion component 3 can be rotated and sprayed in all directions through centrifugal force. The sprayed water flow will hit the scattering plate 35 and then be scattered by the scattering plate 35 to prevent the formation of an umbrella-shaped water film. The formation of an umbrella film will lead to a decrease in the cooling efficiency, so the formation of the umbrella film needs to be suppressed.

[0032] The second dispersing component 4 includes a second supporting plate 41, the top end of the second central axis 25 is fixedly mounted on the middle of the lower surface of the second supporting plate 41, a second conical member 42 is fixedly mounted on the middle of the upper surface of the second supporting plate 41, a plurality of evenly distributed second blades 43 are fixedly mounted on the outer ring of the second conical member 42, the inclination direction of the second blades 43 is opposite to the inclination direction of the first blades 33, and the second blades 43 are inclined, a plurality of evenly distributed partitions 44 are fixedly mounted on the upper surface of the second supporting plate 41, and a plurality of evenly distributed spoon-shaped grooves 45 are provided on the upper surface of the second supporting plate 41.

[0033] When in use, a part of the water flow will pass through the central leakage groove 32 and impact the surface of the second cone 42 and the second blade 43, and then the second dispersing component 4 will rotate as a whole under the impact of the water flow. Because the second cone 42 is conical, it can produce the effect of breaking the water flow. The broken water flow will impact the inside of the spoon-shaped groove 45. Because the spoon-shaped groove 45 is spoon-shaped, the greater the impact of the water flow, the stronger the splashing effect. The rotation of the second support plate 41 will also drive the partition 44 to rotate, and then the water on the surface of the second support plate 41 will be sprayed all around. The first support plate 31 is conical, so the water flow will fall in an oblique downward direction, and the second support plate 41 is flat, and the water flow will be thrown out in a nearly horizontal direction, and then the horizontal water flow will impact the oblique water flow thrown out by the first dispersing component 3, further improving the dispersing effect.

[0034] Working principle: The threaded connection pipe 11 is installed with the outlet pipe of the cooling tower through threads, and the water flow will pass through the guide pipe 5 and impact on the first dispersion component 3, wherein a part of the water flow will pass through the first dispersion component 3 and impact on the second dispersion component 4. When the water flow impacts the first dispersion component 3, a part of the force will be unloaded and dispersed to the surroundings, and the remaining water flow will be blocked by the second dispersion component 4 and dispersed to the surroundings;

[0035] In the actual production process, there are multiple guide pipes 5, and the inner diameter of each guide pipe 5 is different, which can be changed according to the actual liquid being transported. If a higher flow rate is required, a smaller-diameter guide pipe 5 can be replaced. If there are suspended matter or other debris in the liquid that easily causes the device to be blocked, replacing the guide pipe 5 with a larger diameter can reduce the possibility of the device being blocked, so that the device can work more stably and improve practicality. When the nozzle is damaged and worn after being used for a long time, only the guide pipe 5 needs to be replaced, and there is no need to replace the entire nozzle, thereby reducing operation and maintenance costs.

[0036] When the high-speed water flow hits the first blade 33, the first blade 33 rotates under the impact of the water flow. On the one hand, the vertical impact brought by the water flow can be decomposed into a rotational force and a vertical force, reducing the impact of the high-speed water flow on the baffle. In addition, the water flow hitting the first dispersing component 3 can be rotated and sprayed in all directions through centrifugal force. The sprayed water flow will hit the scattering plate 35 and then be scattered by the scattering plate 35 to prevent the formation of an umbrella-shaped water film. The formation of an umbrella film will reduce the cooling efficiency, so the formation of the umbrella film needs to be suppressed.

[0037] A portion of the water flow will pass through the central leakage groove 32 and impact the surfaces of the second cone 42 and the second blade 43, and then the second dispersing component 4 will rotate as a whole under the impact of the water flow. Because the second cone 42 is conical, it can produce the effect of breaking the water flow. The broken water flow will impact the inside of the spoon-shaped groove 45. Because the spoon-shaped groove 45 is spoon-shaped, the greater the impact of the water flow, the stronger the splashing effect. The rotation of the second support plate 41 will also drive the partition 44 to rotate, and then the water on the surface of the second support plate 41 will be sprayed all around. The first support plate 31 is conical, so the water flow will fall in an oblique downward direction, and the second support plate 41 is flat, and the water flow will be thrown out in a nearly horizontal direction, and then the horizontal water flow will impact the oblique water flow thrown out by the first dispersing component 3, further improving the dispersing effect.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
