加高型中心龙卷流型搅拌槽液体搅拌性能研究

Research of Mixing Characteristics in A Higher Central Tornado Flow Stirring Vessel

对加高型中心龙卷流型搅拌槽液体混合性能进行了实验研究。实验设备最大高径比为4／1,采用3种槽径、3种大小不同的挡板、两种桨叶形式。实验表明,加高型中心龙卷流型搅拌槽具有稳定的正常工作区,且在正常工作区内,功率准数与矮型中心龙卷流型搅拌槽相比无明显增大,与标准四挡板搅拌槽相比功率准数低,功率消耗少,具有节能降耗的作用。

Mixing characteristics of a higher central tornado flow stirring vessel was studied. The maximum ratio between hight and diameter was 4/1 in the experimental vessel. There were 3 different diameters of vessels, 3 types of fenders and 2 types of impeller. A stable normal region in higher central tornado flow stirring vessel was observed. It was found this type of stirring vessel has higher efficiency and lower energy consumption than standard stirring vessel.
