摘要: 用自制的实验室型气压过滤机并结合滤饼内部结构的测试,研究了气压过滤的成饼动力学及其滤饼结构的分形特征。结果表明,气压过滤条件下,虽然过滤压差较大,但成饼阶段仍遵循Darcy定律;气压过滤的滤饼结构为一分段Sierpinski分形,其分维数值介于1.775~1.885之间。

Abstract: The cake formation dynamics of air pressure filtration and the fractal constructure of filter cake have heen studied in a laboratory - scale experimental air pressure filter with the observation of filter cake constructure. Results showed that Darcys Law is also followed in the filter formation stage of air pressure filtration, and that the filter cake constructure is a sort of Sierpinski fractal, the fractal dimensions of different filter cake are within 1.775~1.885.
