Abstract:
An apparatus for selectively separating contaminants in a gas, the apparatus comprising:an inlet for receiving a flow of the gas into a chamber; a separator positioned within the chamber for separating the gas into first and second flow streams, the separator having a primary pathway in which the first flow stream comprised primarily of particles of a first size is directed and a secondary pathway in which the second flow stream comprised primarily of particles of a second size is directed, the particles of a second size being larger than the particles of the first size; an ionization region positioned within the chamber and downstream of the separator to receive the gas flow, the ionization region having a charging area located within at least one of the primary pathway and secondary pathway to impart an electrical charge on the particles of the respective flow streams travelling therein; an agglomeration region positioned within the chamber and downstream of the ionization region, the agglomeration region configured to receive the first flow stream of the primary pathway and the second flow stream of the secondary pathway and coagulate the particles of the first size with particles of the second size to form agglomerated particles; and an outlet for exhausting the flow of gas out of the chamber.
