D4.7m风机砼冷却塔的改造

Reconstruction of 4.7 m exhaust fan and concrete cooling tower

用少量投资 ,改造老式 D 4.7m风机及砼塔内部构件 ,使塔内收水、配水、喷淋达到了最佳组合。改造后的冷却塔产生了较高的效率 ,单塔水处理能力由原 30 0 t/ h提高到了 5 0 0 t/ h,进出塔水温差由 5～ 7℃提高到了 8～

To make water collection,distribution and spray in the tower get the best assembling,they reconstructed the vintage 4.7 m exhaust fan and its inside components of concrete cooling tower with less investment. The reconstructed cooling tower can bring higher efficiency,the water disposal capacity of the single tower gets to 500 t/h from 300 t/h,inlet and outlet difference in water temperature gets to 8～9 ℃ from 5～7 ℃.
