Fig. 2 is the top view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
In Fig. 1-Fig. 3, comprise tower body 1, pond 2, noise reduction packing layer 3, heat exchange packing layer 4, water distribution system 5, water collection device 6, noise elimination screen 7, air duct 8, blower fan 9, motor 10, wind deflector 11, air inlet 12, cooling tower 100.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Please refer to Fig. 1-Fig. 3, a kind of low noise cooling tower systems, comprise at least two cooling towers 100 arranged side by side, is three in the present embodiment, and three cooling tower 100 single row types are arranged, often establish structure expansion joint by civil engineering requirement in the middle of row.Each cooling tower 100 comprises the tower body 1 of setting, and housing structure adopts large-span steel-reinforced concrete frame structure, and tower body wall interior panel and longitudinal and transverse dividing plate are glass epoxy.
The top layout of tower body 1 has air duct 8, is provided with blower fan 9 in air duct 8.
Blower fan 9 adopts the special low noise axial fan of high-strength epoxy glass steel material machinery tower, and blade adopts the blade shape of low noise type, and flap-type is cancelled structure, and air quantity is large, and energy consumption is little, can effectively reduce air outlet noise source, thus reduces whole tower noise.Blower fan 9 has reverse function, to utilize hot-air in tower, eliminates the ice curtain at air inlet 12 place.
