摘　　要：针对同一梭锥管浑浊流体分离装置分别采用孔口出流排泥和管道排泥两种不同的排泥方式,同时考虑梭锥管倾角不同对排泥耗水率、排泥水的浓缩率和"清水"的出水量及其含沙浓度的影响进行泥沙水动态沉降试验研究。试验结果表明:梭椎管的排泥耗水率、浓缩率和"清水"的出水量与排泥方式密切相关。梭锥管采用管道排泥浓度远高于孔口排泥浓度,排泥水浓缩率可达5倍以上,耗水率仅为10%左右,仅为孔口排泥耗水率的20%。梭椎管倾角对耗水率与浓缩率影响较小,倾角为60°时,耗水率最小,浓缩率最大。要保证较小耗水率和较大溢流量排泥方式是关键因素。Based on the same turbid flow isolation device- shuttle-conical tube ,this paper adopts mud flow orifice and mud pipeline in two different mud ways, taking into account different dip angles of shuttle-conical tube affecting mud water consumption rate, mud concentration rate and ＂water＂ out of water and sediment concentration carries out water dynamic settlement. The ruslts show that mud water consumption, concentration ratio and ＂water＂ out of water are closely related to the mud way. Shuttle-conical tube utilizes mud pupline, its sediment concentration is higher than mud flow orifice and mud concentration rate up to 5 times, the consumption rate is only 10% or so. The impactof dip of shuttle-conical tube is small to consumption rate and concentration. When dip is 60 degrees, the consumption is minimum and the concentration is maximum. To ensure smaller consumption and more overflow, the way of mud is a key factor.
