摘要
与常规冷却塔相比,高位收水冷却塔无雨区,但在填料下方增加了收水装置。收水装置是高位塔的核心部件,其结构型式直接影响冷却塔的阻力特性及填料断面风速分布,研究收水装置的阻力特性对于冷却塔设计计算具有重要意义。本文采用流体计算软件,研究了收水装置气流特性。通过数值模拟计算,给出了不同深度的收水装置阻力系数值;并对数值计算模型进行了验证。研究成果可供高位收水冷却塔的研究和设计参考。
Compared with common natural draft cooling tower, cooling tower with WCD(water collecting device) has no rain zone but WCD was added.WCD was the key part of the tower, its structure not only affected the resistance of the tower but also affected the air velocity distribution of the fill, study on resistance characteristics of WCD made sense for the cooling tower design. A CFD model was set to study on it in the paper by Fluent, the resistance values of WCD in different depth were given, the results can be used for the design of cooling tower with WCD.
