摘要
介绍了闭式冷却塔的结构组成、工作原理和应用特点,分析研究了闭式冷却塔在北方寒冷地区冬季运行存在的防冻问题。结合实际工程案例对闭式冷却塔进行设备和自动控制改造方案设计,应用结果表明该方案对于解决闭式冷却塔冬季运行防冻问题是可行的。
The structure composition,working principle and application characteristics of the closed cooling tower are introduced,and the anti-freezing problem of the closed cooling tower in winter in northern cold regions is analyzed and studied.Combined with the actual engineering case,completed the design of the equipment and automatic control transformation scheme for closed cooling tower.The results of application show that the scheme is feasible to solve the problem of anti-freezing of the closed cooling tower in winter.
