1. A vortex breaker for a particulate separator, the particulate separator comprising a vessel having an inner wall, an inlet, a first outlet, and a second outlet adjacent to a bottom of the vessel, the vortex breaker comprising:
a first set of vanes spaced along a perimeter of a first shape;
a second set of vanes spaced along a perimeter of a second shape, the perimeter of the second shape residing within the perimeter of the first shape; and
a vertical axis positioned within the perimeter of the second shape;
wherein:
each of the vanes in the first set of vanes and the second set of vanes has a top edge, a bottom edge, an inside edge, and an outside edge;
each of the vanes in the first set of vanes intersects the perimeter of the first shape, and the outside edge is spaced outward and in a first rotational direction about the vertical axis relative to the inside edge;
each of the vanes in the second set of vanes intersects the perimeter of the second shape, and the outside edge is spaced outward and in a second rotational direction about the vertical axis relative to the inside edge, the second rotational direction being opposite the first rotational direction; and
the first set of vanes and the second set of vanes define fluid flow paths between the outside edges of the vanes in the first set of vanes and the inside edges of the vanes in the second set of vanes.
