Abstract
The article presents the results of a research of the process of removing particles in range 2.5 µm that are most dangerous to human health using ultrasonic coagulation. The two-stage gas clearing system consisting of the agglomerator and the cyclone dust collector (supplemented by an ultrasonic radiator) was proposed and made. The carried out investigations have revealed the optimal conditions for the formation of a swirling flow, providing high efficiency coagulation of fine-dispersed particles. The formation of a swirling gas-dispersed flow in the conditions of ultrasonic exposure provides an increase in the average particle size 2.5 µm by 4.5 times due to particles convergence and the formation of local areas with high concentration. In this case, the ultrasonic effect on a rectilinear flow with 2.5-μm particles allows increasing particles size of only 1.6 times. The ultrasonic exposure has increasing 2.5-µm particle clearing efficiency from 46 to 85% by optimal conditions for gas-dispersed flow.
