Abstract. Dust emissions from waste air streams and gases from agricultural process plants and production facilities significantly worsen environmental conditions, increase fire risk, and harm human health.
For the deep purification of gases from suspended impurities, the scheme of sequentially arranged cyclones and electrostatic precipitators is increasingly used. Therefore, it is advisable to combine the action of electric and inertial forces in one unit.
The purpose of the study was to develop a simplified mathematical description of the process of inertial separation of dust in flow cyclones when applied electrostatic field on a vortex dusty stream.
The analysis of the process of dust removal from ventilation cases of technological equipment and production facilities in centrifugal-inertial separators operating according to the flow scheme. The question of the use of electric field in cyclone processes is considered. The effect of determining forces, including electrical, on the motion of a dust particle in a rotating stream is analyzed. Equations describing the motion of a particle in an air rotating stream under the action of an electric field have been determined, and mathematical models have been developed to calculate the trajectory of the motion of a dust particle. Simplified analytical expressions for particle trajectories are presented. Calculations, as examples, are graphical representations of defined trajectories.
It is established that the use of an electrostatic field in flow cyclones allows to control the process of dust separation without changing the hydrodynamic mode of operation of the cyclone. The use of air-dust swirling in tubular electrode filters helps to increase their efficiency.
Key words: dust, separation, electric field, cyclone, airflow
