This thesis will put forward a new design project that aimed at discussing the packing sets of natural - draft counter - flow dry cooling tower , which is the research and application of the spray nozzle . the content mainly includes the experimental study of the application of the jnx - 01 spray nozzle in cooling tower , as well as the heating calculation 本文将针对自然通风逆流湿冷式冷却塔中影响效率较大的淋水装置提出设计改进方案，即旋转式喷溅装置的研究与应用，内容主要包括jnx - 01型节能旋转式喷溅装置及旋转溅水碟式喷头在冷却塔上应用情况的试验研究及热力计算。
This article briefly explains the basic principle of coherent jet technology , and contrasts the characteristics of coherent jet with supersonic jet , accordingly the coherent jet technology has lower decay , longer jet distance and less absence of dimple etc , to form into a greater depth of penetration for any stand - off distance and ameliorate the effect of mixing round for liquid 摘要简述了集束射流技术的基本情况，与传统超音速射流的特性进行了对比，从而看出集束射流具有发散小、喷射距离远和喷溅少等特点，可以形成较大的穿透深度，改善了对钢液的搅拌效果。
