Mathematics Model and Theoretical Solution of Deep Bed Filtration under Constant Pressure

摘要

Studying from the physical model of deep bed filtration, combining with the law of conservation of mass and classical filtration formulas, the clarification equation, continuity equation and relational expression of accumulation amount and liquid concentration are deduced, which are applicable for the deep bed filtration under constant pressure. Combining theoretical deduction with experiment results, expression of filtration coefficient that is the most important parameter of filtration process is determined. On this basis, mathematics model of deep bed filtration under constant pressure is established, solving process and equations of theoretical solution are introduced. All these results are helpful for filtration operation.
