摘　　要：新型立式压滤机入料速率对单位产能以及滤饼中泥沙所占体积分数的影响还未被完全揭示。通过Fluent流体仿真软件研究了立式压滤机滤室内的泥浆压滤过程,得出了泥沙的运动规律和入料速率对过滤效率的影响。当入料速率低于0.4 m/s时立式压滤机的滤室没有被泥浆填充满,压滤机的单位产能较低。当入料速率大于0.8 m/s时会导致滤室内出现“架桥”现象,同时物料会从入料口溢出。经过分析可以得出最佳入料速率为0.6 m/s,立式压滤机单位产能达到最大,滤饼中泥沙所占的体积分数可达90%。The effect of the feed rate of the new vertical filter press on the unit capacity and the volume fraction of sediment in the filter cake has not yet been fully revealed.Therefore,the mud press filtration process in the filter chamber of vertical filter press was studied,and the influence of sediment movement rule and feeding rate on filtration efficiency was obtained using Fluent fluid simulation soft-ware.When the feeding rate is lower than 0.4 m/s,the filter chamber of the vertical filter press is not filled with mud,and the unit ca-pacity of the filter press is low.When the feeding rate is greater than 0.8 m/s,the phenomenon of"bridging"willoccur in the filter chamber,and the material will overflow from the feeding port.After analysis,it can be concluded that when the optimal feeding rate is 0.6m/s,The vertical filter press has the maximum capacity per unit time,and the volume fraction of sediment in the filter cake can reach90%.
