摘要
对负压差下立管 -翼阀系统的气固流动特性进行了理论分析 ,并系统地考察了翼阀结构、操作条件、颗粒物性等对立管 -翼阀系统中气固两相流动的影响 ,得到了稳定操作状态下料腿中料封高度的计算式。hD=MFAρb D(1 0 .1 0 sinβsin(α-β) +76.2 6) +(p2 -p1 )ρbg D -1 1 2 .3 W2ssin(α-β)ρ2bg D +1 9.8W2sρ2bg D+2 .
The flow characteristics of standpipe trickling valve system under negative differential pressure was theoretically analyzed and experimentally studied. The influences of the structural factors of trickling valve, operating conditions and particle properties were systematically investigated, and some quantitative results were obtained. The sealing height of the standpipe can be expressed as follows:hD=M F Aρ b D(10 10 sin β sin (α-β)+76 26)+(p 2-p 1)ρ b gD-112 3W 2 ssin (α-β)ρ 2 b gD+19 8W 2 s ρ 2 b gD+2 70
