1、石油化T·9l6·PETROCHEMICALTECHNOLOGY2012年第41卷第8期旋转浮阀塔板的流体力学性能研究张绪满,姚克俭,何健烽,刘炳炎(绿色化学合成技术国家重点实验室培育基地浙江T业大学化学T程与材料学院,浙江杭州310032)[摘要]在内径600mm的有机玻璃塔内,以空气一水为物系,对旋转浮阀塔板的流体力学性能进行研究。测定了塔板压降、漏液量和雾沫夹带等流体力学性能参数,并与F1型浮阀塔板进行对比。实验结果表明,旋转浮阀塔板的关闭平衡点的阀孔动能冈子(F0)比F1型浮阀塔板约高3.70%,开启平衡点的比Fl型浮阀塔板高3.
2、54%;当大于关闭平衡点而小于升启平衡点时,旋转浮阀塔板的压降和F1型浮阀塔板压降基本相同;当大于开启平衡点时,旋转浮阀塔板的压降比F1型浮阀塔板高3.79%~9.73%;旋转浮阀塔板的漏液分率I:LF1型浮阀塔板约低21.19%;旋转浮阀塔板的雾沫夹带率比Fl型浮阀塔板低50%以上;旋转浮阀塔板的操作弹性大于F1型浮阀塔板。[关键词]F1型浮阀塔板;旋转浮阀塔板;流体力学性能;漏液;雾沫夹带[文章编号]1000—8144(2012)08—0916—05[中图分类号]TQ053.5[文献标识码]AHydrodynamicPerforman
