山西晋城煤层气粉尘净化研究初探

Primary investigation of CBM-dusts purification in Jincheng of Shanxi

对比分析了3种滤芯在实际生产条件下的净化总效率、分粒度净化效率、运行稳定性、生产安全性、可再生性等主要指标,评述了实验室检测数据。结果表明,经特殊设计的具有通透拦截效应的高镍金属滤芯较通过聚结原理工作的纤维型滤芯更胜任高流速、粉尘浓度多变且含湿煤层气的工作条件,其技术指标更具优势。

This paper investigated and compared the gross-efficiency of purification ,efficiency of sizing particles purification ,stability of operation ,safety of exploitation and economy of three types of filtration cores in the practical condition . Through test data evaluation , the result showed that the special designed nickel-based metal filtration core with the effects of penetration ＆ interception is more competent than that of fiber filtration core with the effects of coalesce in the CBM purification featured with high flow velocity ,variable concentration of dusts and water-containing ,and it has technology and economy advantages .
