摘要
利用固体激光发生器和扭矩仪对固体颗粒体积浓度为5%的偏心搅拌槽内颗粒的悬浮特性进行试验研究,分析了偏心率、转速和桨叶离底高度对临界悬浮转速、功率消耗和混合时间的影响。研究发现,偏心搅拌能改善颗粒分布效果,降低混合时间,并提高颗粒的临界悬浮转速和功率消耗。
Solid-liquid suspension performance in eccentrically stirred tank is investigated with experimental method by using solid state laser generator and torque sensor. The volume concentration of the solid particles is 5%. This paper mainly analyzes the influence of eccentricity, rotational speed and the height of agitator from bottom of the vessel on criti cal suspension speed, power consumption and mixed time. It has been shown that eccentric stirring can improve the effectiveness of particle distribution and reduce mixed time obviously, which can raise the critical suspension speed and power consumption.
