  • Patent number: 10913073
    Abstract: The present invention includes a device, a system, and a method for enhancing a particle separation efficiency, including a particle charging device adapted to impart predominately unipolar charging on a plurality of particles in a fluid stream, e.g. a gas stream; wherein the particle charging device is positioned upstream from and adapted to provide the plurality of particles charged by the particle charging device to a particle deflection device capable of separating the particles charged by the particle charging device from a core fluid flow that is substantially free of dust particles.
