摘要
在大型冷模流化床（Φ710mm／Φ870mm）实验装置上，对外置式旋风分离器下口有约束的料腿中的气固两相流动规律进行了不同工况的实验，并作了理论分析。应用流态化理论，给出了在本实验操作范围内维持下口有约束的料腿正常下料所需的最小充气量的计算公式。
On a large-scale (Φ710/Φ870 mm in diameters)fluidized bed cold modl experiments of gassoidtwo-phase flow in the constrained dipleg of external cyclone separator were conducted underdifferent condi-tions and theoretical analysis was carried out. Based on the fluidization theory, calualution formula for the mini-mum amount of the filled gas maintaining normal down-flow rate from the constrained dipleg within the rangeof the experimental operating conditions was given.
