• 摘要: 基于某百万级核电站冷却塔配置比较及优化分析，高位收水塔方案年运行费用优于常规塔方案，冷却塔采用高位收水装置后，能有效降低水泵几何扬程，节省运行费用。淋水面积越大，采用高位收水装置的经济优势越大。根据数模试验结论，高位收水塔应进行塔内填料布置深度优化，即减小外围填料厚度、增大内围填料厚度，最终实现冷却塔整体热力性能的最大化。

   

  Abstract: Based on the 1000MW nuclear power station cooling tower's allocation and optimization, the high-level water collecting cooling tower's annual operating costs is less than the conventional tower's, it's used by collection device, and can effectively reduce the pump geometry head, and also can save the annual operating costs. The larger of the filling area, it can get the more economic advantages of using high-level collection device. The numerical simulation according to the conclusions, the high-level water collecting cooling tower should be used by depth optimization about filling arrangement, reducing the thickness of the external filling, increasing the thickness of the internal filling, and ultimately finishing the overall thermal performance of the cooling tower.
