Three-Phase Mathematical Model of Dehydration and Granulation Process in the Fluidized Bed

Bogdan Korniyenko | Svetlana Borzenkova | Lesia Ladieva

Abstract: The developed mathematical model takes into account the hydrodynamics of the fluidized bed, the contact of droplets with particles and their adhesion to the surface, as well as the kinetics of drying the solution on the surface of the particles. When creating a model, the process of dewatering and granulation in a fluidized bed is considered as a heterogeneous three-phase process, during which interact with three separate phases particles - granulation centers, the starting material - ammonium sulfate in the form of droplets and heat carrier - air. To get the dynamic characteristics of the developed system, the Simulink library of the Matlab application package is used. With the help of built-in library elements, a scheme of differential equations describing the model of the control object is obtained.
