双动力源冷却塔设计研究

通过对冷却塔进行循环冷却水节能分析并对进塔水流的富裕能量进行研究,开发了一种低比转速混流式水轮机。考虑到冷却塔循环冷却水水流不稳定而出现水轮机输出动力不足或富裕的问题,选用与该微型水轮机相匹配的电动机作为其备用动力源,并通过自动离合装置与微型水轮机相连接,同时在进水管道上安装了旁通阀。通过智能控制器控制电动机以及旁通阀来调整水轮机与电动机的工作方式以满足冷却塔风机的需求并达到了节能的目的。

Research and design of cooling tower with double power sources

T hr ough the ener g y sav ing analysis of the cooling tow ers and the research o f the surplus energ y of the cir culating cool2 ing w ater, a low specific speed mixed2flow turbine has been developed in t his paper . The instability o f the circulating coo ling w a2 ter in the co oling tower may cause the problems o f insufficient o r ex cessiv e output power fr om the tur bine. The electr ic mot or matching with the micr o2turbine w as selected as the standby power source, and co nnected with the micr o2turbine thr ough the automatic clutch device. M eanw hile, the bypass valve w as installed on the wat er pipe. I n or der to meet t he needs of cooling tow er fan and to achieve the purpose o f energ y saving , the electr ic mo tor and bypass v alv e w ere co ntro lled by the intellig ent contr oller to adjust the o per ation mo de of elect ric mot or and turbine.
