摘　　要：对高径比０．３的φ５０聚丙烯短阶梯环填料，在φ５００ｍｍ冷模塔中进行实验研究并应用于φ２．４ｍ工业塔中，发现与相同公称直径的阶梯环和鲍尔环比较，这是一种综合性能优异的散堆填料。For the φ50 PP-short-cascade rings packing with height to diameter ratio of 0.3, the hydrodynamical performance was experimentally investigated in a 500mm ID test column and its industrial application was made in a 2. 4m ID industrial column respectively. Compared with those of the cascaderings and Pail-rings with the same nominal diameter, the results show that this is a superior performance random packing.
