Hydraulic Performance Research on the Splash Device—XX TP-III 28 mm Nozzle Diameter

摘要: 喷溅装置作为冷却塔配水系统的核心部件，其水力学性能直接影响淋水均匀性与填料换热效率。为明确XX TP-III型喷溅装置的水力特性，为冷却塔优化设计提供数据支撑，本文通过喷溅装置模型试验系统，对该装置在不同水头压力下的流量系数、均布系数及喷溅半径进行了系统测试。试验在XX TP-III型喷溅装置的套管喷嘴口径为28 mm、喷淋高度1.0 m的条件下，设置0.6~1.4 m共5个工作水头工况，试验结果表明：该喷溅装置的平均流量系数为0.91，流量特征数为8.867，溅水均布系数至0.025~0.216；喷溅半径与水压呈正相关，水压越高，喷溅范围越宽广。该研究成果验证了XX TP-III型喷溅装置优良的水力学性能，可为冷却塔配水系统选型及参数优化提供重要参考。

Abstract: As the core component of the water distribution system in cooling towers, the hydraulic performance of the splash device directly affects the water distribution uniformity and the heat exchange efficiency of packings. To clarify the hydraulic characteristics of the XX TP-III sprayer and provide support for the optimal design of cooling towers, this paper conducts systematic tests on the flow coefficient, uniformity coefficient and splash radius of the device under different water head pressures through a splash device model test system. The test was carried out on the XX TP-III sprayer with a nozzle diameter of 28 mm and a spray height of 1.0 m, with 5 water head conditions set in the range of 0.6~1.4 m. The test results show that: the average flow coefficient of this splash device is 0.91, the flow characteristic number is 8.867, and the water splash uniformity coefficient ranges from 0.025 to 0.216; the splash radius is positively correlated with water pressure—the higher the water pressure, the wider the splash range. The research results verify the excellent hydraulic performance of the XX TP-III splash device, which can provide important reference for the selection and parameter optimization of the water distribution system in cooling towers.
