摘要
在综合分析国内外涡管螺旋流排沙技术主要研究成果的基础上，对螺旋流的形成及排沙机理、涡管泄流比和排沙率以及涡管设计和实际应用情况，作了全面而综合的介绍，并提出了自已的观点，指出了有待进一步深入研究的问题。
Based on the synthetic analyses of the main research achievements of the vortex tube sand trap, silt extractor, technique at home and abroad, the formation of spiral flow and mechanism of sediment escaping, the discharge ratio and sediment discharge rate, the design and practical application of vortex tube were introduced comprehensively in this paper. Also, the paper presented the authors own opinions and pointed out the pending problems.
