| 摘 要： | 采用脉冲应答技术测定了矩形气液固三相流化床反应器中液相混合时间和下降速度。考察了挡板结构、气液流量、固体浓度对床层液相混合行为的影响。实验结果表明，在床中设置挡板构件，对液体混合时间与液体下降速度的影响不明显。

| Abstract: | Effects of baffle, gas and slurry flow rate and solids loading on liquid phase axial mixing performance were measured using the tracer response technique in a rectangle gas-liquid-solid three-phase fluidized bed reactor with a multiple-layer shutter-like baffle. It is found that the presence of baffle decreases in certain extent the liquid mixing time in the section under the baffle and slightly increases the liquid descending velocity in the downcomer. |
