An anti-mixing cover is presented to restrain the generation of unsteady flow and back-flow phenomena in the separation chamber of a cyclone separator with reduced height. Structure of the anti-mixing cover is proposed based on the Barth balance orbit theory hypothesis. In order to clarify the effect of the anti-mixing cover on the separation efficiency of the cyclone, a numerical model was established by means of the Euler-Lagrange approach. The simulation results are in good agreement with the experimental data and several empirical formulas in the range of inlet air velocity 18 m/s~23 m/s. As results, the anti-mixing cover effectively enlarged the centrifugal force acting on particles and reduced the vortex intensity at the bottom of the cyclone. Moreover, the rising dust-laden airflow is also blocked by the anti-mixing cover which leads to less back-mixing phenomena.
