Abstract:
A device for removing airborne particulate comprising:at least one chamber having an airstream inlet at an upstream end and an airstream outlet at a downstream end, an air mover cooperating with said at least one chamber so as to urge an airborne particulate laden airstream into said at least one chamber through said inlet, in a flow direction along a flow path through said at least one chamber, and out of said at least one chamber through said outlet, at least one water sprayer mounted to said at least one chamber for mixing a spray of water with said airstream in said flow path, at least one slurry collecting element mounted entirely across and in said flow path so as to seal across said chamber to prevent bypass of said airstream around said collecting element, said collecting element downstream of said water sprayer, said at least one slurry collecting element including at least two separate parallel and adjacent rigid grids, offset relative to one another to overlap grid spacings of said grids so as to reduce in size but not close off an effective grid opening spacing normal to said flow direction in said flow path, said at least one chamber having a slurry remover therein for removing from said at least one chamber slurry collected by said at least one slur collecting element.
