摘　　要：漏斗式全沙排沙设施是一种排沙耗水量小、截沙率高的泥沙处理技术。有关其清、浑水流场特性试验分析表明 ,漏斗室内部水流特性有利于水沙分离和泥沙的排除。在工程实际应用中取得了良好的效果 ,平均耗水量为电站引水流量的 2 71% ;粒径为 0 2 5～ 0 5 0mm的泥沙排除率为 96 10 %。The funnel shaped desilting facilities have the characteristics of low water consumption and high sand interception rate Tests and analysis on the flow field of clear water and muddy water show that the water flow characteristics inside the funnel chamber is favorable to the separation of water and sand and the removal of sand The engineering practice shows that the funnel shaped desilting facilities have good desilting effectiveness Its average water consumption is 2 71% of water diversion discharge for power plant The sand disposal rate is up to 96 10% for the sand with the grain diameter of 0 25～0 50 mm
