摘　　要：静电增强纤维过滤是非稳态过程,其压力降随时间变化,但现有研究中定量描述的几乎没有。为得出压力降随时间变化的关系式,在推导静电增强纤维过滤非稳态压力降公式时将压力降视为由滤料及沉降粉尘共同作用而产生,并认为带电后的粉尘受极化力的作用而有形成 “粉尘粒子串”的趋势,从而得出静电增强纤维过滤非稳态压力降公式,此式可用于定量计算和定性分析。Electrostatic enhancement fabric filtration is in non-steady state because the filtration抯 pressure drop changes as time goes on. But none theoretical models are set up to describe this. To obtain the accurate formula of pressure drop, we suppose that pressure drop is made by filter and depositing dust together and the charged dust has the tendency to form 揹ust fiber? We can use the formula set up by us to calculate the number of pressure drop and analyze the influencing facts.
