依据旋流型中心喷嘴(XPH 型)和溅水碟型伞式喷嘴(TP–Ⅱ型)两种喷嘴的淋水性能实验研究，分析喷嘴各参数及不同布置方式的全塔喷嘴群布水的综合效果。结果表明：XPH 型喷嘴的流量系数低，适用于工作水头压力 ph≥10,kPa的工况，TP–Ⅱ型喷嘴则需依靠喷嘴间相互组合作用达到布水均匀；冷却塔外围靠近壁面的淋水可采用XPH型喷嘴的正三角形布置；中部主空气流速区域宜采用 TP–Ⅱ型的正四边形布置，以增大淋水密度和均匀性；中心区域可采用 TP–Ⅱ型的正六边形布置，以降低淋水密度且减少投资。分析结果可为冷却塔布水的优化设计和改造提供定量参考。

Based on the spray performance experiments of XPH and TP-Ⅱ nozzles,the water distribution throughout the whole tower affected by different parameters and arrangement of nozzles was analyzed. The results show that the flow coef-ficient of XPH is low and able to apply to the condition where pressure head is larger than 10,kPa. Groups of TP-Ⅱ nozzles should be used to make water well distributed. XPH nozzles should be positioned as an equilateral triangle at the wall zone in the tower. The middle zone full of air should be controlled by TP-Ⅱ nozzles arranged as a square. TP-Ⅱ nozzles distributed as a regular hexagon should be used at the core of the tower to reduce the spraying consistency and investment. The results can provide quantitative references for the optimization of cooling design and transformation.
