新型高效多管旋风分离器的开发及应用

介绍了石油大学等单位新近开发应用的立式三旋(EPVC系列旋风管和PDC型旋风管)以及卧式三旋(PT-Ⅱ型旋风管)的结构特点。EPVC旋风管通过改进叶片设计方法,提高了细颗粒分离效率;采用分流型芯管排气结构,提高了细粒的捕集率;在泄料盘中心开喇叭形孔,解决了泄料堵塞问题。PDC型旋风管单管气量大,除尘率高,排料通畅,无窜流返混。PT-Ⅱ型旋风管采用双道切向人口和长锥体结构,分离效率高于PDC型。

DEVELOPMENT AND COMMERCIAL APPLICATION OF HIGH-EFFICIENCY NEW MULTI-TUBE CYCLONES

Configuration features of both vertical(with cyclone tubes of EPVC series and PDC type) and horizontal(with PT-II type cyclone tube) third stage cyclones newly developed by University of Petroleum and other institutes and commercially applied were introduced. The configuration of EPVC cyclone tube was improved by the following ways:(l) enhancing fine particles separation efficiency by improving the de-sign method of vanes;(2) increasing catching percentage of fine particles by adoption of exhausting structure with by-pass type core tube;(3) eliminating discharge blocking by drilling a tappered hole at the centre of the discharge pan. PDC type cyclone tube is characterized by large gas capacity per unit tube, high effi-ciency of dust removal, unobstructed discharging as well as elimination of gas channeling and backmixing. Adopting the dual-channel tangential inlet and long taper configuration, the separation efficiency of PT-II type cydone tube is higher than that of PDC type.
