| 摘 要： | 运用流体力学的基本理论,对多层桨的液泛、再循环这两种重要现象作了描述,得到多层桨液泛点和再循环起始点的判据n_(F2)=2.8Q~(0.5)D~(0.2)/d~2;n_(F3)=2.6Q~(0.5)D~(0.2)/d~2;n_(Rm)=1.1Q~(0.2)D/d~2(m=2,3),以及适宜的操作范围n>n_R>n_F(式中,n、Q、D、d分别为转速、通气量、搅拌槽内径、叶轮直径;下角F、R分别为液泛点、再循环起始点),并在实验的基础上,提出多层桨功率数据的放大方法。

| Abstract: | The criteria of flooding and onset of recirculation, which are very useful for thescaleup of the reactor, ware given and the optimum mixing conditions were proposedaccording to the analysis of the fluid motion, In addition, the gassed power consump-tion of six-blade disk turbines was investigated over a wide range of operating condi-tions. Finally, the criteria mentioned above combining with the power data have beenused to obtain a set of equations for calculating the gassed power of industrial reactors. |
