- 論文の詳細を見る
The flow pattern of solids within stirred beds in batch operation was studied by following tracer particle movement in a cylindrical tube. In addition, in stirred-fluidized and moving beds with continuous flow of solids, the F-curve to a step input of a tracer was determined by the electric capacitance method under various conditions. From the observation of solids movement in a stirred bed in batch operation and characteristics of the F-curves, a flow model for the stirred moving bed was developed by considering a plug flow zone, two perfect mixing zones and a dead space zone with a circulation of solids within the beds, and the F-function was derived according to the flow model. The model parameters are evaluated by matching the F-function to the experimental data, and the effect of operating conditions on the model parameters is discussed.
