Abstract: The present disclosure generally relates to cyclonic separation or filtering of nanoparticles suspended in a gas. A plume of liquid droplets may be generated using an ultrasound or other generator. The gas may be mixed with the plume of liquid droplets, which may have received an electrostatic charge prior to mixing, to promote preferential adhesion of the nanoparticles to the liquid droplets. The gas with suspended nanoparticles and suspended liquid particles may flow through a cyclonic separator that spins rapidly, causing the cleaned gas to flow out of the filter while the liquid with adhered nanoparticles may be discharged, collected, and/or re-used in the plume generator. By causing nanoparticles to adhere to larger liquid particles, the filter may allow the filtering and collection of much smaller particles than current systems may filter under atmospheric pressure.
