滤布阻力对恒压过滤最佳操作周期的影响

The Effect of Filter Cloth Resistance on the Optimal Filtration Cycle under Constant Pressure

导出考虑滤布阻力时恒压过滤最佳操作周期的严格公式,并给出了忽略滤布阻力对最佳周期影响的严格判据(M-判据),对该判据的研究表明,当过滤辅助时间较短时,简单地根据滤布阻力当量滤液量和实际滤液量之比(Ve/V)来判断能否忽略滤布阻力对最佳操作周期的影响是不够充分的。

Rigorous formulas for the optimal filtration cycle were given with filter cloth resistance is considered. Whether the effect of the filter cloth resistance can be ignored depends on a certain M-factor. It is not sufficient to estimate the effect of filter cloth resistance on optimal filtration cycle according to the ratio of equivalent filtrate to the actual volume（Ve/V）.
