Performance evaluation of a cyclone with granular packed beds

Utilization of rice-husk packed beds as fine dust collectors at heavy dust loadings

“…As another alternative, the concept of sphericity (F S ) was also applied to the rice-husk particles. Generally, sphericity is defined as the surface-volume ratio of a spherical particle with a diameter of D P divided by the surfacevolume ratio of the actual particle with an effective diameter of D S [19,20]. Based on the present experimental results, the effective sphericity of the rice husks was estimated to be 0.82.…”

“…Since the size of rice husk or filter media was much larger than the primary dust size, the adhesion forces between a piece of the rice husk and CaCO 3 dust particles can be considered to be quite weak. As particles continued to deposit and accumulate in the front zone of the bed, the local bed porosity would decrease, thereby causing the interstitial gas velocity and the corresponding pressure drop to increase [20]. The high dust loading could also facilitate cake formation on the bed surface.…”

Approximated Solution of Estimating Cyclone Efficiency for Polydispersed Aerosol

“…C yclone separators are widely used in the field of aerosol sampling and to remove dust from industrial gas streams (Licht, 1988;Jung et al, 2004;Zhao and Su, 2006;Jung and Park, 2008). The main reasons for the widespread use of cyclones are that they are inexpensive and they can be constructed to withstand harsh operating conditions.…”

A Simplified Model to Estimate the Size Distribution Change of Polydispersed Aerosol for Cyclone Separator

“…In addition to use in pollution control, cyclones are employed extensively in various process industries. Cyclone separators provide a method of removing particulate matter from airstreams at low cost and low maintenance (Licht, 1988;Jung et al, 2004).…”
