废塑料的分离是固体废物回收利用的重要组成部分。基于高密度聚乙烯（HDPE）和聚丙烯（PP）的密度差异，采用实验研究和CFD数值模拟相结合的方法，对旋流器轻介质分离技术的分离性能进行了研究。结果表明，随着进料流量的增加，压降呈幂函数增加，牛顿效率在进料流量为3.6 m3/h时达到最大值，在PP/HDPE颗粒体积比为2.0时达到最大值。
The separation of waste plastics is an important part of solid waste recycling. Based on the density difference between high density polyethylene (HDPE) and polypropylene (PP), this paper used the experimental research and CFD numerical simulation to study the separation performance by using the light medium separation technology with hydrocyclones. Results showed that with the increase of feed flow rate, the pressure drop increased as a power function, the Newton efficiency peaked at the feed flow rate of 3.6 m3/h and peaked at the volume ratio of PP to HDPE particles of 2.0 respectively.
