Description

Technical Field

[0001] The utility model belongs to the field of cooling towers, in particular to a mechanical dust-proof and noise-reducing cooling tower. Background Art

[0002] The cooling tower is one of the commonly used equipments in various types of equipment. Its main function is to dissipate heat to cool water. The mechanical ventilation cooling tower is to set a fan at the top of the tower to enhance air convection, thereby cooling the water. However, it will generate wind noise during operation, and the level of noise is also an indicator for evaluating the performance of the cooling tower. Moreover, for factories with high water quality requirements, they will also have requirements for the water quality of the cooling water prepared by the cooling tower. When the fan is running, it sends air into the tower, which leads to the risk of dust in the air being sucked into the tower. At present, there are also many literatures focusing on the dust and noise reduction of cooling towers. For example, the document No. CN218410787U "A closed cooling tower with dust and noise reduction", CN220288288U "A circulating water cooling tower with sound absorption and noise reduction" and CN215217257U "A turbine cooling tower with anti-dust function" all disclose related structures, but they all have the disadvantages of complex structure and inconvenient maintenance.

[0029] As Figure 1 shown, this embodiment provides a mechanical dust and noise reduction cooling tower, including a cooling tower body 1. A ventilation opening 11 is provided at the upper end of the cooling tower body 1, and a fan 12 is provided in the ventilation opening 11. A packing layer 13 is provided in the cooling tower body 1. A dust and noise reduction device 2 capable of ventilation is also provided at the ventilation opening 11. The packing layer 13 in the cooling tower body 1 is provided with multiple layers in the up and down direction. The dust and noise reduction device 2 has a sound-insulating sleeve 22 and a dust-proof sleeve 21 arranged in sequence from outside to inside. By providing a dust and noise reduction device at the ventilation opening, the air flow sent into the cooling tower body from the ventilation opening can be dust-removed by the dust and noise reduction device. In addition, the wind noise of the fan can be reduced, so that the entire cooling tower has the function of dust and noise reduction.

[0030] As Figure 2 and Figure 3As shown, the dust cover 21 in the above technical solution is in the shape of a groove, with its groove facing downward and docking with the vent 11 of the cooling tower body 1. It has a simple structure and a large filtering area for the airflow, so that the airflow can be dust-removed without affecting the air intake of the cooling tower body. Specifically, the dust cover 21 includes a first hollow frame 211 and a dust bag 212. The first hollow frame 211 is in the shape of a groove, and the dust bag 212 is sleeved outside the first hollow frame 211, and the groove end of the first hollow frame 211 faces downward and docking with the vent 11 of the cooling tower body 1. The first hollow frame 211 is used to expand the dust bag 212 at the vent 11. It has a simple structure. By expanding the dust bag by the first hollow frame, it can be ensured that the dust bag can remain in the expanded state under the action of internal negative pressure. In addition, when the dust bag is in the expanded state, its dust filtering area is the largest and the dust filtering efficiency is the best.

[0031] like Figure 2 and Figure 3 As shown, the sound insulation sleeve 22 in the above technical solution is in the shape of a groove, with its groove facing downward and sleeved outside the dust cover 21. By arranging each sleeve outside the dust cover, the sound insulation sleeve can wrap the dust cover for noise reduction, which has a good noise reduction effect and does not affect the air flow of the dust cover. Specifically, the sound insulation sleeve 22 includes a second hollow frame 221 and a breathable sound insulation bag 222. The outer side of the notch end of the first hollow frame 211 is provided with a first outer flange 213, and the second hollow frame 221 is in the shape of a groove. , and its notch end faces downward and is provided with a first inner flange 223, the breathable sound insulation bag 222 is sleeved on the second hollow frame 221, and the second hollow frame 221 is sleeved outside the dust bag 212, and there is a gap between the two, the first inner flange 223 and the first outer flange 213 are bolted and installed at the vent 11, so that the second hollow frame opens the breathable sound insulation bag, which makes the breathable sound insulation bag have a good sound insulation effect and can pre-filter large particles of dust.

[0032] The material of the sound insulation sleeve 22 in the above technical solution is breathable sound insulation cotton, which has good breathability and good sound insulation effect.

[0033] In the above technical solution, a second outer flange 111 is provided at the ventilation port 11, and a second inner flange 214 is also provided at the slot end of the first hollow frame 211. The second inner flange 214 is bolted to the second outer flange 111. In this way, the entire dust and noise reducer 2 is easy to disassemble and assemble at the ventilation port, which makes its overall maintenance convenient.

[0034] like Figure 1 and Figure 2As shown, the dust and noise reducer 2 in the above technical solution further includes a rain shield 23. A support ring plate 224 is further provided on the outer side of the notch end of the second hollow frame 221. A plurality of vertically arranged support rods 231 are circumferentially spaced on the support ring plate 224. The rain shield 23 has a conical groove, and its notch faces downward and is connected to the upper ends of the plurality of support rods 231. In this way, the rain shield can block rain outside the sound insulation sleeve, thereby preventing the breathable sound insulation bag and the dust-proof bag from being wet in rainy days and affecting their air permeability.

In addition, there is a gap between the sound insulation sleeve and the dust-proof sleeve for air flow to buffer between the two, and there is an annular gap between the rain shield and the sound insulation sleeve, so that the rain shield will not affect the air from entering the gap between the sound insulation sleeve and the dust-proof sleeve through the sound insulation sleeve.

[0037] In the above technical solution, a rain shield 232 is further sleeved on the lower ends of the plurality of support rods 231. The upper end of the rain shield 232 extends into the groove of the rain shield 23, and there is a gap between the upper end of the rain shield 232 and the rain shield 23 to form a ventilation hole. By setting the rain shield, it can cooperate with the rain shield to better protect the dust and sound insulation bag from rain, and at the same time, it does not affect the air from entering the cooling tower body through the breathable sound insulation bag and the dust-proof bag.

[0038] As Figure 1 As shown, the material of the packing layer 13 in the above technical solution is modified PVC material with hydrophilic and oleophobic properties. The packing layer 13 is a corrugated packing layer, which has a simple structure and enables water to have better film-forming properties on the packing layer, so that the heat exchange between water and air is more efficient, thereby improving the cooling effect of the entire cooling tower. The packing layer has the function of being hydrophilic and oleophobic, which can prevent the oil film from accumulating on the packing layer, and further improve the film-forming property of water on the packing layer.
