摘　　要：开发出一种新型高效节能搅拌设备———中心龙卷流型搅拌槽 ,对其固 -液悬浮特性的研究 ,采用试验方法测试固 -液悬浮临界转速 ,关联出临界转速方程 ,得出其放大规律。试验表明 ,中心龙卷流型搅拌槽固 -液悬浮性能优于标准搅拌槽 ,在相同条件下其临界转速低 。In order to reveal the suspension characteristics of central tornado flow stirring vessel,we studied the critical velocity (N js ) of the solid suspension in liquid.A dimensionless equation was developed,which could be used for scale-up purpose.It was found that the central tornado flow stirring vessel was superior to the standard stirring vessel,because of its higher efficiency and lower energy consumption.
