Abstract: Direct-flow cyclones are widely used for gas cleaning from dust. However, due to low efficiency, they are mainly used as a pretreatment gas cleaning from dust to reduce the load on the fine cleaning machines. The analysis of the combined direct-flow cyclone with the elements in which, for better concentration of dust both the centrifugal and Coulomb forces are used. It is known that near the corona electrode, the Coulomb force is much greater than the centrifugal force, but as the distance increases it decreases rapidly. Centrifugal force, on the contrary, increases linearly with increasing distance from the corona electrode. It is found that for particles of a certain size there is the distance from the corona electrode, where the centrifugal and Coulomb forces are equalized. At this distance, the resultant force (the action of Coulomb and centrifugal forces) becomes minimal. The minimum resultant force can significantly simplify the theoretical analysis of the mechanism of dust concentration, assuming that this force is constant throughout the interelectrode space. It is found that the combined effect of Coulomb and centrifugal forces significantly increases the efficiency of direct-flow cyclone, so further researches in this direction are promising.
