摘　　要：通过数值模拟方法研究泥渣收集器中的流场特性以及各关键因素对泥渣收集器收集性能的影响规律。研究发现,不同切割方式对泥渣收集器流场的影响可以忽略,随着泥渣颗粒浓度的增加,泥渣收集器单次收集量不断增加,但是单次收集率保持不变;在泥渣收集器进出口孔径不变的情况下,随着颗粒粒径的增加,泥渣收集器的收集能力增加;每种颗粒粒径都存在一个最优的泥渣收集器进出口孔径。Numerical simulation was used to study the flow field characteristics of sludge collector and the effects of key factors on the collection performance. Studies have shown that the effects of different cutting modes on the flow field characteristics of sludge collector could be ignored. With the particle concentration increased, the amount of single mass collection increased, but the single collection efficiency unchanged. Under the condition of the same inlet and outlet of sludge collector, with the particle diameter increased, the collection capability of sludge collector increased. There was an optimum inlet and outlet aperture of sludge collector in each particle diameter.
