This paper presents a study of the effect of regime and geometric parameters on the fractional separation of fine particles in a working area of the proposed separation chamber. The main feature of the vortex chamber is an annular barrier in the region where a two-phase flow leaves the separation zone. The size, position, and swirl of such an obstacle allow one to affect the aerodynamic pattern and, consequently, the boundary size of the separated particles. The presence of a rotating paraxial cylinder in the vortex chamber design provides a more uniform field of the circumferential velocity component, which has a positive effect on aerodynamic conditions within the chamber. The physical parameters of single- and multicomponent ceramics are used in calculations of fractional separation of dispersed particles. Analysis of the calculated results shows that when calculating and evaluating the parameters, it is extremely important to take into account gas pulsations of the fractional separation due to their effect on the separated fine particles. New data on aerodynamics within the considered chamber and the calculated data on the fractional separation of single- and multicomponent ceramics in the studied area of the separation element are presented.
Keywords: vortex chamber, swirling two-phase flow, fractional separation of particles by size, ceramics.
