| 摘 要： | 在卧式搅拌床反应器冷模实验装置中，使用不同的聚丙烯粉料，采用脉冲示踪法测定了不同搅拌桨结构下的停留时间分布，同时分别采用多级全混釜串联模型和双参数模型对实验结果进行了模拟计算。结果表明：叶片桨的卧式釜搅拌返混最大，最接近于全混流；T型桨的卧式釜搅拌返混最小，最接近于平推流。

| Abstract: | Using different polypropylene powders, the residence time distribution was determined by pulse trace method in the cold model experimental apparatus of a horizontal stirred bed reactor (HSBR) equipped with different kinds of stirring paddles. The experimental data were simulated with multi-level model of the whole mixed reactor in series and two-parameter model, respectively. The results demonstrate that the back-mixing degree of leaf blade agitator was the maximum and most close to a fully back mixed flow; the back-mixing degree of T-type agitator was the minimum, and most close to the plug flow. |
