Dust Collecting System for the Cleaning of Atmospheric Ventilation Emissions

摘要

The paper gives a description of a dust collecting system for the cleaning of atmospheric ventilation emissions. The system includes two successively installed vortex dust collectors with countercurrent swirled flows. The exhaust is organized from the first-stage hopper. After the cleaning in the additional device of the same design, the exhaust dust-air mixture is delivered to the lower inlet of the second-stage dust collector. The forecast evaluation of the system efficiency was carried out on the basis of the solution of balance equations for dust flows. The experimental evaluation of the system efficiency was carried out in industrial conditions on the basis of the full factorial experiment. The dependence characterizing the efficiency of the suggested system was obtained on the basisof the investigation results, and the most rational modes of the system operation were determined.
