摘　　要：导流筒是调浆搅拌槽的重要部件之一,首先分析了几种常见调浆搅拌槽的导流筒结构特点,运用CFD数值分析的方法分析了常见导流筒调浆搅拌槽的流场。针对目前调浆搅拌槽大型化的发展趋势,分别对适用于大流量工况的裙式导流筒和BK型导流筒的调浆搅拌槽结构以及流场特点进行了分析,为调浆搅拌槽的设计与优化提供决策依据。Draft tube is one of the important components in Pulp-Mixing tank,this paper analyses the structure characteristics of several kinds of common draft tubes firstly, using CFD numerical analysis methods to analyze the flow field characteristics of Pulp-Mixing tank with common draft tubes.For the current development trend of large-scale Pulp-Mixing tank, the paper analysis the structure and the flow field characteristics of skirt and BK draft tube which is suitable for large flow. It provides decision-making basis for design and optimization about Pulp-Mixing tank.
