圆盘反应器成膜性能的实验研究

在直径为0.48m圆盘反应器内研究了物料黏度、液位、圆盘转速等因素对反应器功率、最小成膜转速、持液量以及膜厚的影响规律。结果表明:最小成膜转速随黏度的增加而降低,随液位的降低而升高;持液量随黏度和转速增加而增大,黏度较低时增加的趋势低于黏度较高时;无因次混合时间随着线速度的增加先减小后增加;同时得到了功率准数以及膜厚的关联式。

Film-forming characteristics in a rotating disk reactor

The factors affecting power consumption,minimum film-forming speed,liquid hold-up and film thickness in a rotating disk reactor of diameter 0.48m have been investigated experimentally.The results show that the minimum film-forming speed decreases with increasing viscosity and liquid level.The hold-up increases with increasing viscosity and rotation speed especially at lower viscosity.The dimensionless mixing time initially increases and then decreases with increasing tip velocity.The correlation equations f...
