Abstract
A method of centrifugal separation of particles, comprising providing a gas flow containing the particles, charging the particles in the gas flow, generating an aerosol of polar liquid droplets introducing the aerosol into the gas flow for attracting the charged particles by the polar liquid droplets, and separating the liquid droplets comprising the attracted particles from the gas flow by the centrifugal separation.
Claims13
A method of centrifugal separation of particles, comprising:
- providing a gas flow containing the particles;
- charging the particles in the gas flow;
- generating an aerosol of polar liquid droplets;
- introducing the aerosol into the gas flow for attracting the charged particles by the polar liquid droplets;
- and
- separating the liquid droplets comprising the attracted particles from the gas flow by the centrifugal separation.
An apparatus for performing centrifugal separation of particles, wherein a gas flow is provided containing the particles, comprising in serial fluid interconnection:
- an electrostatic charging device for charging the particles in the gas flow;
- an aerosol generator for generating an aerosol of polar liquid droplets in a mixing vessel, wherein the aerosol is introduced into the gas flow to attract the charged particles by the polar liquid droplets;
- and
- a centrifugal separator for separating the liquid droplets comprising the attracted particles from the gas flow by centrifugal separation.
A method of centrifugal separation of particles, comprising
- providing a gas flow containing the particles;
- charging the particles in the gas flow;
- generating an aerosol by vibration of a polar liquid in contact with the gas flow;
- introducing the aerosol into the gas flow for attracting the charged particles by the polar liquid droplets of the aerosol;
- varying a cross section of the gas flow comprising the introduced aerosol;
- and
- separating the liquid droplets comprising the attracted particles from the gas flow by centrifugal separation.
