Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a cooling tower with a noise reduction structure. Background Technology

[0002] Cooling towers, as commonly used industrial equipment, absorb and discharge industrial waste heat using water as a circulating coolant. However, they suffer from numerous problems during operation. The water spraying process generates low, medium, and high-frequency noise, and the impact of water flow, fan rotation, and airflow turbulence exacerbate the noise, affecting the surrounding environment. Common noise reduction methods, such as building sound barriers, require a distance from the cooling tower to ensure air intake, increasing the footprint, which is particularly problematic in land-scarce areas. Some components of the noise reduction mechanism, such as sound-absorbing strips, require complete disassembly and replacement for later maintenance, making undamaged parts unusable and resulting in resource waste. Furthermore, disassembly and assembly are inconvenient, affecting cleaning and maintenance efficiency. In addition, spraying devices often suffer from uneven spraying, leading to insufficient heat exchange between the cooling medium and the air, resulting in poor cooling effects in some areas and affecting overall efficiency. Utility Model Content

[0003] The main objective of this invention is to provide a cooling tower with a noise reduction structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cooling tower with a noise reduction structure includes a bottom pool, a filter screen fixedly connected to the upper part of the inner wall of the bottom pool, a cooling tower shell disposed directly above the bottom pool, the lower end face of the cooling tower shell being flush with the lower end face of the bottom pool, double T-slots with through front ends being opened on the lower part of the lower left and lower right inner walls of the cooling tower shell, an inspection door being movably installed on the left front end of the bottom pool, a cooling noise reduction filling structure being movably connected in both double T-slots, an air inlet noise reduction structure being disposed on the lower inner wall of the bottom pool, an air outlet duct being fixedly connected to the middle upper end of the cooling tower shell, an exhaust fan being disposed on the upper part of the inner wall of the air outlet duct, and a uniform spraying device being fixedly connected to the rear right end of the bottom pool.

[0005] Preferably, the cooling and noise reduction filling structure includes an outer shell, with double T-blocks fixedly connected to the middle of the left and right ends of the outer shell. The front end of the outer shell has three through-hole filling slots from top to bottom. A honeycomb guide plate layer, an elastic buffer mesh layer, and a porous rubber sound-absorbing pad are movably inserted into the three filling slots respectively. A drain groove is provided at the upper end of the outer shell, and several through-holes are provided on the lower inner wall of the drain groove.

[0006] Preferably, the plurality of the openings are arranged in a rectangular array, and the outer shell communicates with the interior of the cooling tower shell through the plurality of openings and three filling slots.

[0007] Preferably, the outer casing is slidably connected to the cooling tower shell via two double-T blocks and two double-T slots, and the outer casing is located directly behind the inspection door.

[0008] Preferably, the air intake noise reduction structure includes a fixed frame, which is embedded in the lower inner wall of the bottom pool. Eight arc-shaped sound-absorbing louvers are provided in the fixed frame, and a sound-absorbing cavity is formed between two adjacent arc-shaped sound-absorbing louvers.

[0009] Preferably, the eight arc-shaped sound-absorbing louvers are distributed at equal intervals, and the area of ​​the fixed frame is smaller than the area of ​​the bottom pool.

[0010] Preferably, the uniform spraying device includes a pump body, which is fixedly connected to the rear right end of the bottom pool via a water inlet pipe. A water outlet pipe is fixedly connected to the output end of the pump body. The end of the water outlet pipe away from the pump body extends into the upper part of the cooling tower shell and is fixedly connected to a U-shaped pipe. Four first nozzles are fixedly connected to the lower left and lower ends of the U-shaped pipe. Three connecting pipes are fixedly connected to the middle front end of the U-shaped pipe. Four second nozzles are fixedly connected to the lower outer surface of each of the three connecting pipes.

[0011] Preferably, the U-shaped tube is located directly above the outer casing and below the air outlet, and the four first nozzles arranged in two longitudinal rows are symmetrically distributed from left to right.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the cooling noise reduction filling structure and the air intake noise reduction structure are used together to significantly improve the noise reduction effect and maintenance convenience of the cooling tower. The outer shell is slidably connected by double T-blocks and double T-slots, which can be easily disassembled from the inspection door, facilitating the maintenance and replacement of internal components and avoiding the waste of resources caused by overall disassembly. At the same time, the inspection door with sound insulation material can form a closed space when closed with the outer shell, which can reduce noise and prevent liquid from flowing out. The honeycomb guide plate layer in the three filling slots can sort the airflow and reduce turbulent noise. The elastic buffer mesh layer can alleviate the impact of water flow to reduce impact sound. The porous rubber sound-absorbing pad can effectively absorb low, medium and high frequency noise. The three-layer structure works together to reduce water spray and airflow noise in multiple dimensions. The arc-shaped sound-absorbing louvers of the air intake noise reduction structure form a sound-absorbing cavity, which further weakens the intake noise while ensuring smooth air intake. It does not require additional space, takes into account both noise reduction and space utilization, and improves the environmental protection and practicality of the cooling tower.

[0013] 2. In this utility model, the various components of the uniform spraying device work together to efficiently extract the cooling medium from the bottom pool and transport it to the upper part of the tower. Through the symmetrical layout of the U-shaped tube and the extension design of the connecting pipe, multiple nozzles form a comprehensive spraying range. The symmetrical distribution of nozzles on the left and right sides, combined with the supplementary spray at the front end, ensures that the cooling medium is evenly sprayed on the filling structure below, greatly increasing the contact area with air and the heat exchange efficiency, avoiding the problem of insufficient local cooling. This design not only ensures the uniformity of spraying but also improves the overall cooling effect of the cooling tower. At the same time, the reasonable structural layout allows it to work in conjunction with other components in the tower, enhancing the stability and efficiency of equipment operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-4 This utility model provides a technical solution: A cooling tower with a noise reduction structure includes a bottom pool 1. A filter screen 2 is fixedly connected to the upper part of the inner wall of the bottom pool 1. A cooling tower shell 3 is installed directly above the bottom pool 1. The lower end face of the cooling tower shell 3 is flush with the lower end face of the bottom pool 1. Double T slots 4 with through front ends are opened in the lower part of the lower left and lower right inner walls of the cooling tower shell 3. An inspection door 5 is movably installed on the left front end of the bottom pool 1. A cooling noise reduction filling structure 6 is movably connected in both double T slots 4. An air inlet noise reduction structure 7 is provided on the lower inner wall of the bottom pool 1. An air outlet duct 8 is fixedly connected to the middle of the upper end of the cooling tower shell 3. An exhaust fan 9 is provided on the upper part of the inner wall of the air outlet duct 8. A uniform spraying device 10 is fixedly connected to the rear right end of the bottom pool 1.

[0020] In this embodiment, the cooling and noise reduction filling structure 6 includes an outer shell 61. Double T-shaped inserts 62 are fixedly connected to the middle of the left and right ends of the outer shell 61. Three through-hole filling slots 63 are sequentially opened from top to bottom on the front end of the outer shell 61. A honeycomb-shaped guide plate layer 64, an elastic buffer mesh layer 65, and a porous rubber sound-absorbing pad 66 are movably inserted into the three filling slots 63, respectively. A drain groove 67 is opened at the upper end of the outer shell 61. Several through-holes 68 are opened on the lower inner wall of the drain groove 67. These through-holes 68 are arranged in a rectangular array. The outer shell 61 passes through these through-holes... The opening 68 and three filling slots 63 communicate with the interior of the cooling tower shell 3. The outer shell 61 is slidably connected to the cooling tower shell 3 through two double-T inserts 62 and two double-T slots 4. The outer shell 61 is located directly behind the inspection door 5. The air intake noise reduction structure 7 includes a fixed frame 71, which is embedded in the lower inner wall of the bottom pool 1. Eight arc-shaped sound-absorbing louvers 72 are provided in the fixed frame 71. A sound-absorbing cavity 73 is formed between two adjacent arc-shaped sound-absorbing louvers 72. The eight arc-shaped sound-absorbing louvers 72 are evenly distributed. The area of ​​the fixed frame 71 is smaller than the area of ​​the bottom pool 1.

[0021] Through the above solution: the cooling and noise reduction filling structure 6 is slidably connected to the double-T slot 4 through the double-T plug 62 of the outer shell 61, which is convenient for disassembly and assembly from the maintenance door 5. At the same time, when the maintenance door 5 and the outer shell 61 are closed, a closed space can be formed to reduce noise and prevent liquid from flowing out. In addition, it also solves the problem of traditional sound absorption components needing to be replaced as a whole, reducing resource waste and improving maintenance efficiency. Its internal honeycomb guide plate layer 64 sorts the airflow to reduce turbulent noise, the elastic buffer mesh layer 65 weakens the water flow impact sound, and the porous rubber sound-absorbing pad 66 absorbs low, medium and high frequency noise. The three-layer structure works together to reduce water spray and airflow noise. The arc-shaped sound-absorbing louvers 72 of the air intake noise reduction structure 7 form a sound absorption cavity 73, which further reduces noise while ensuring air intake. No additional partition is required, saving floor space. The overall noise reduction effect is optimized and practicality is taken into account.

[0022] In this embodiment, the uniform spraying device 10 includes a pump body 101. The pump body 101 is fixedly connected to the rear right end of the bottom pool 1 through a water inlet pipe. The output end of the pump body 101 is fixedly connected to a water outlet pipe 102. The end of the water outlet pipe 102 away from the pump body 101 extends into the upper part of the cooling tower shell 3 and is fixedly connected to a U-shaped pipe 103. The lower left and lower ends of the U-shaped pipe 103 are fixedly connected to four first nozzles 104. The front middle of the U-shaped pipe 103 is fixedly connected to three connecting pipes 105. The lower outer surface of the three connecting pipes 105 is fixedly connected to four second nozzles 106. The U-shaped pipe 103 is located directly above the outer shell 61 and below the air outlet duct 8. The four first nozzles 104 arranged in two longitudinal rows are symmetrically distributed from left to right.

[0023] The above scheme involves pumping cooling medium from the bottom pool 1 through pump body 101 and delivering it to U-shaped pipe 103 via water outlet pipe 102. Utilizing the symmetrical structure of U-shaped pipe 103, along with the four first nozzles 104 on its lower left and lower parts and the four second nozzles 106 on the three connecting pipes 105 in the middle of its front end, a multi-directional, full-coverage spray layout is formed. Because U-shaped pipe 103 is located directly above the outer shell 61, the spray water can act evenly on the cooling and noise reduction filling structure 6, ensuring that the cooling medium and air are in full contact for heat exchange, avoiding the problem of poor local cooling effect, and effectively improving the overall cooling efficiency of the cooling tower.

[0024] It should be noted that this utility model is a cooling tower with a noise reduction structure. During use, firstly, when the cooling tower is working, the cooling water in the bottom pool 1 is drawn by the pump body 101 and transported to the U-shaped pipe 103 through the water outlet pipe 102. Then, it is evenly sprayed onto the cooling noise reduction filling structure 6 by the first nozzle 104 and the second nozzle 106. The exhaust fan 9 operates to allow outside air to enter the tower through the air intake noise reduction structure 7. The arc-shaped sound-absorbing louvers 72 and the sound-absorbing cavity 73 reduce the intake noise. The air and sprayed water are absorbed by the honeycomb guide plate layer 64, the elastic buffer mesh layer 65, and the porous rubber sound-absorbing layer. The pads 66 make full contact for heat exchange, and the heat is discharged through the air outlet 8 after being carried away. The filter screen 2 intercepts impurities, and the double T plug 62 cooperates with the double T slot 4 to facilitate the maintenance and replacement of the cooling and noise reduction filling structure 6. In addition, the soundproof inspection door 5 can form a closed space when closed with the outer shell 61, which can reduce noise and prevent liquid from flowing out. Therefore, this design improves the cooling efficiency through the uniform spray device 10, and the cooling and noise reduction filling structure 6 and the air intake noise reduction structure 7 work together to reduce noise. The modular design facilitates maintenance and achieves efficient cooling and low-noise operation in a compact space.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
