“…Since the first cyclone dust collector was put into production in 1885, it has been more than 100 years of industrial application history [9][10][11][12]. Due to the limited understanding of its dust removal mechanism and process characteristics, the cyclone dust collector has a low initial dust-removal efficiency, and the minimum particle size that can be separated is more than 40-60 μm [13][14][15][16].…”

In order to further improve the trapping effect of fine particles, a new electrostatic cyclone precipitator (ECP) with magnetic confinement was proposed, the overall efficiencies of fine particles under different operating conditions were numerically simulated, and the influence of working voltage on the dust-removal effect of fine particles with and without magnetic field were discussed. The results show that increasing working voltage or magnetic induction intensity improves the trapping performance of spherical cylindrical magnetically confinement ECP, and the lifting effect gradually weakens while increasing the same amplitude. The results can offer technical reference for the optimization design of greatly improving the ECP dust-removal performance.

“…The global efficiency improved when they use a high bed depth. Srinives et al (2010) utilized a rice-husk packed bed as fine dust collectors at heavy dust loading. They found that the rice husk packed bed could exhibit an effective performance in capturing fine dust at various dust loadings with a collection efficiency higher than 85% by mass.…”

The cement industry is the major source of cement dust which contains heavy metals like nickel, cobalt, lead, chromium, arsenic and hazardous substances like dioxins and furans. Exposure to these substances can cause health problems to human, animals and vegetation. A continuous pilot scale quartz sand filter was constructed and uses to study the effect of important design parameters (temperature, pre-loaded dust on the collector, diameter of the filter, bed depth, collector size and superficial velocity) on its performance for cleaning of cement dust from air. Initial penetration and initial pressure drop (after 180s) were measured and compared for different variables used in this study. The dirty bed was cleaned by means of reverse air flow when the pressure drop across the filter rises to 20 cmH₂O. A macroscopic model describes the filter clogging was used to predict the effluent histories based on initial collection efficiency (Î·₀)_exp which was determined from experimental data. A removal efficiency of more than 99% was obtained. The results show that 0.4% of cement dust still adheres on the quartz sand bed after 5 min of cleaning cycle. The presence of 0.4% of pre-load dust on the quartz sand filter enhanced the efficiency and low initial penetration, moderate initial pressure drop was obtained. At given Empty Bed Contact Time (EBCT), with different filter diameters 30 and 15 cm, a sharp decrease in initial penetration from 0.41-0.03 was obtained respectively. A nonlinear relationship between penetration and temperature was found. The initial penetration can be reduced by using smaller filter diameter, small collector size and collector with pre-load dust with 0.4%. The experiment that operates at a filter diameter of 15 cm and temperature of 25Â°C represent the minimum penetration among all the experiments
