Simulation Research of the Particles’ Track in Cyclone Separator

Abstract:

This paper mainly focuses on the numerical simulation of particles trajectories aiming at obtaining the movement regulations of particles with different diameters. The article takes advantage of random orbital model of phase coupling under Lagrange coordinate, and figures out that the movement of small particles has large randomness, meanwhile particles with the same diameter and different initial positions can reach various final positions, some of which can escape or be captured from the exhaust pipe. Particles trajectory can be different even if it has same diameter and initial position. The conclusion of this thesis also puts forward that three different phenomena of presentation of gray ring, short-circuit of exhaust pipe and back-mixing of dust exhaust can appear under any conditions. Almost all large particles can be captured by the cyclone separator, and few particles show retention and short time rotation in the lower part of exhaust pipe.
