Abstract: The correlation equations of gas holdup in three different types of external-circulation-loop reactors are developed for air-water system. The resistance calculation for fluid flow in the loop results in a resistance equation. The gas holdup and liquid circulating rate for a given gas injection rate can be predicted with the correlation equations and the resistance equation, providing the basis for the scaling up of this reactor.

摘要： 本文通过空气-水体系,对三种不同结构的外环流反应器中的气含率数据进行了关联,得到了有意义的模型关联式.对环路进行了阻力计算,得到了包含结构参数的阻力方程.计算发现模型关联式与阻力方程联立求解,可以很好地预测不同结构的外环流反应器中的气含率和循环液速,从而为该反应器的工程放大提供了依据.
