The distinction would be that:
* in the cyclone precipitator, higher-density ( than the air ) particulates are centrifuged outwards ( like pigs and cows in a tornado ) to the inner wall boundary layer of the enclosure, where gravity will ultimately carry them ( precipitate ) to the bottom for disposal.
* VGs create vortex lift along their longitudinal flow edges, as in the Space Shuttle, Concord SST delta-wings, and fixed on a boundary wall, this low edge pressure helps induce the downwash which helps the flow hug the contour. Not without some cost.
