摘　　要：应用传质理论,采用微元分析方法,建立滤饼洗涤分散模型;通过一阶迎风格式及QUICK格式,求解出该模型的数值解。以文献数据进行验证,证明该模型是合理的,对同类性质物料的滤饼洗涤具有重要的指导意义。The permutation model of cake washing was established by using the microelement analysis method based on mass transfer theory. The numerical simulation of this model was analyzed through first-order upwind difference scheme and QUICK scheme. Its rationality was validated by data from references. The results provided valuable guidance for the cake washing process of similar materials.
