Separation assembly with a single-piece impulse turbine

A separation assembly comprising:

• a housing;
• a jet that expels a fluid within the housing;
• and
• a turbine positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet, the fluid causing the turbine to rotate about a center rotational axis within the housing,
• the turbine comprising a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end, the plurality of vanes defining axially-extending channels between each of the plurality of vanes, the first axial end being axially open such that fluid can flow unblocked axially through the first axial end and into the axially-extending channels,
• wherein the jet is positioned such that at least a portion of the fluid enters into the turbine through the first axial end,
• each of the plurality of vanes extends axially between a top end and a bottom end, the top end closer to the first axial end of the turbine than the bottom end, wherein each of the plurality of vanes comprise an impingement surface on a first side thereof and a backside on a second side thereof, wherein the fluid from the jet is directed to the impingement surface, the portion of the impingement surface at the top end of each of the plurality of vanes is further forward than the rest of the impingement surface in a rotational direction of the turbine, and
• the turbine defines an axial gap between each of the plurality of vanes and within the axially-extending channel that extends axially unimpeded straight from the first axial end to the second axial end of the turbine.
