【摘要】 根据纤维滤材的过滤实验研究和颗粒的拦截吸附机理 ,提出了网络模型概念 ,并由此推出纤维滤材阻截概率函数 .对该阻截概率函数曲线进行分析得出 ,就阻截概率而言 ,随着颗粒尺寸的增大 ,阻截概率也增大 ,但增大的速率随着颗粒尺寸的增大而有所减小 .为了有利于对小颗粒的过滤 ,应选择对颗粒有吸附作用的纤维 ,或者经过特殊处理使纤维具有吸附作用 ,以改善纤维滤材的性能 .更多还原

【Abstract】 According to the test results of filter material and the filtration mechanism of particles, the reseau model of fiber filter is proposed. The function of the pond chance is deduced. By studying the function of the pond chance, it can be conclucled that the pond chance is proportional to the sizes of particles. But, when the size of particles are greater, the increasing rate of the pond chance decreases. In order to separate the smaller particles, the filter material with absorption ability is the best selection.更多还原
