Abstract:

The invention is a device which provides for separation of contaminants from a relatively high velocity stream of gas. The invention provides a first stage wherein the gas stream is decelerated and the contaminant particles are caused to separate from the air stream by interacting with a first surface. The interaction results in the particles to acquire a radial velocity vector and by virtue of the momentum of the contaminants particles. The contaminant particles are forced to the outer layer of the gas stream. The second stage of separation provides for further magnification of the radial velocity vector and also induces a slight tangential velocity component to the contaminant particle. By impacting the contaminants against a vane mounted within the gas stream, the contaminant particles, as a result of this impact, acquire a slight swirl or circular motion which causes the contaminant particles to be more localized. In the next stage of the cleaning device, the gas stream is rapidly accelerated by decreasing the area through which the gas stream must travel.
