过滤除尘 meaning in Chinese

dust removal by filtration

Based on the experiment of dust removal in a granular layer at normal temperature and the analysis of the experimental results , the influence of filter particle diameter , layer thickness and filtration velocity on the dust removal efficiency was researched
摘要在常温下，采用固体颗粒层进行过滤除尘的实验研究，并对实验结果进行分析，探索了过滤介质粒径、过滤层厚度和过滤速度对除尘效率和床层压力差的影响。
