Nanoparticle aerosol generator

摘要

A nanoparticle aerosol generator, comprised of a vibrating fluidized bed with a baffle, a vibrating Venturi disperser and a cyclone separator. To generate nanoparticle aerosols, the nanoparticle aerosol generator uses the multiple impaction, vibrating air flow and vibrating high speed air flow to break up larger agglomerates, and multiple dilution to minimize the re-agglomeration of the particles.

主权项

1. A nanoparticle aerosol generator capable of dispersing agglomerates of particles comprising:
a vibrating fluidized bed including a baffle and a cylinder, wherein the cylinder includes:
a proximal end and a distal end, each end containing one or more air feed ports connected to air feed tubes in which clean air can be pulled into the cylinder;an exit port at the distal end above the distal air feed port and connected to a Venturi disperser that is connected to a cyclone separator;a vibrator attached at the proximal end;a filter supported by an air distributor attached at the proximal end above the proximal air feed port; the baffle attached at the distal end having a hole near the exit port; wherein the Venturi disperser can create a negative pressure in the cylinder.
