Abstract:
1. A multiple vortex separator for removing solid and liquid waste from a waste stream while withdrawing a substantially moisture-free airstream under suction comprising: a housing having an outer wall with an inner surface, a waste inlet for receiving the waste stream, and an enclosed top with an exhaust port for withdrawing the substantially moisture-free airstream from the housing; an annular channel along the inner surface of the wall defining a first vortex flow path for separating liquid and solid waste from the waste stream, the annular channel being in communication with the inlet; and inner and outer nested cones within the housing defining an inverted conical cavity between the cones, the conical cavity being in communication with the exhaust port and forming a second vortex flow path isolated from the first vortex flow path for separating additional liquid and solid waste from the waste stream before it is withdrawn from the exhaust port.
