Embodiment Construction

[0016] In the following detailed description, reference is made to the accompanying drawings which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It is readily apparent that the aspects of the disclosure generally described herein and illustrated in the drawings may be arranged, substituted, combined and designed in many different configurations, all of which are expressly contemplated , and become part of this disclosure.

[0017] While nanoparticles have many new uses and beneficial applications, they also have the potential to create new health risks. For example, while humans and organisms have evolved biological mechanisms over t...

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.

Description

[0001] Cross References to Related Applications [0002] Priority is claimed to US Application 12 / 714,078, filed February 26, 2010 and identified by Attorney Docket No. MTCW001701, entitled "NANOPARTICLE FILTRATION." Background technique [0003] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and inclusion in this section is not an admission that it is prior art. [0004] Nanoparticles have a large surface area and small volume, giving them different properties and different effects than materials with the same chemical composition. This high surface-to-volume ratio can make the nanoparticles more chemically active and more biologically active, potentially leading to medical and / or environmental damage. [0005] Nanoparticles come from several sources in the environment. Engineered nanoparticles are used in a variety of technical and consumer products such as cosmetics, sunscreens, textiles, coat...
