水电站引水渠道上的涡管排沙工程

Flushing Sediment by Vortex Tube on the Canal of Diversion Type Power Station

涡管排沙主要处理渠系推移质问题，但也可处理悬移质中的有害粒径泥沙。通过试验取得涡管分流比、截沙率和挟沙能力三方面的计算公式。对设计水电站引水渠道涡管排沙工程的程序提出了建议并给出设计实例。

Thes paper introduces a new technigue of flushing sediment by vortex tube on the canal of diversion type power station. By the experimental method and theoritical analysis,three parameters for design are obtained, i. e, the diversion ratio of the flow, the trapping efficiency of the vortex tube and the carrying capacity of the tube procedure of design of the vortex tube is advised and an example is given.
