摘    要:研究了具有盘管、碟形底和斜叶涡轮固液悬浮搅拌槽的放大规律。试验用槽径(外径)分别为0.2m、0.5m和1.0m的三个有机玻璃搅拌槽。用激光法测定悬浮液浓度。得出离底悬浮及均匀悬浮时搅拌转速和比功率的经验关联式,与测定槽内轴向速度分布所导出的均匀悬浮方程相吻合,并表明槽径的放大指数主要由循环流数所决定。

关 键 词:悬浮  搅拌槽  放大  固液悬浮

Abstract:Scale-up of stirred-tank with a coiled pipe, dished bottom and agitator with a inclined-blade turbine for solids in liquid suspension was studied. Experiments were conducted in three plexiglass-tanks of 0.2,0.5and 1.0m diameter respectively.The suspension concentration was measured by laser method.Empirical correlations of stirring speed and specific power both for off-bottom suspension and for homogeneous suspension were obtained. The latter one agrees with the equation of homogeneous suspension derived from the axial velocity distribution.The results show that the scale-up exponent of tank diameter mainly depends on the recycle volumetric flow number.
Keywords:s:suspension  stirred-tank  fluid flow  scale-up
