The Theoretical Study on Squeeze Dewatering Course

摘要

By using the whole cake as studied object and taking the cake permeability, cake thickness and cake inner hole water pressure as variational parameters, the theoretical equations of the relation between dt / dV and filtrate discharging flux V and the relation between filtrate discharging flux V and operation time t of the first squeeze dewatering course and the second squeeze dewatering course are established based on Darcy basal law. The theoretical study matches well with testing data which solves the problems of lying in rather big errors between the traditional theoretical study and test result and lacking of practicability of the traditional theoretical study.
