湿法磷酸反应器性能的研究

采用脉冲法测定单槽──双搅拌浆反应器的混合时间，并作出密度分布函数Ｅ（ｔ）曲线，用辛普生法计算了平均停留时间和方差。结果表明，当搅拌强度为２５０～４００转／分时，反应区混合达到均匀；该反应器兼有单槽和多槽串联的特征；混合效果取决于器内流体的流动行为、设备尺寸、搅拌强度等因素。该反应器用于二水物法草取磷酸模型试验，结果令人满意。

Study on The Behavior or Reactor Producing Phosphoric Acid

The mixing time in a Single reactor (mixer) with a diaphragm and equipped with blades wasmeasured by impules testing and the diagram of the poinedistrihution function [E (t) diagram] wasdrawn. The mean nesidence time and the variancr of the distriblution ( ) is calcutated by usingsimpson's rule The resultS Shewed that the mixing effect can be uniforimly achieved when the speedof the stirrer is at 250-400r/min. The mixer is characteristics of Single and multiple tank; Themixing effect is dependent on the behavier of the fluid-flow, Size of the equipment and the speedof the Stirrers and so on. The mixer is good at doing the experiment of production of phosphoricacid.
