Abstract:
1. Apparatus for removing dust particles from the atmosphere during cleaning of a generally flat surface, said apparatus comprising: a compressed air source; a water reservoir; a first controller coupled to said compressed air source for controlling compressed air flow; and a first nozzle coupled to said compressed air source and to said water reservoir for receiving said compressed air flow and a water flow, wherein said compressed air flow reduces said water flow to a fine mist of water droplets, and wherein said water droplets engage and become attached to the dust particles and remove the dust particles from the atmosphere above the first portion of the generally flat surface by depositing the dust particles on the generally flat surface under the influence of gravity, wherein said first nozzle includes a first inner housing coupled to said water reservoir and having a first aperture therein through which the water is directed, said first nozzle further including a second outer housing disposed about said first inner housing and coupled to said compressed air source, said second outer housing further including a second aperture concentrically disposed about said first aperture for directing compressed air about and upon the water discharged from said first aperture wherein said second outer housing forms a third annular aperture concentrically disposed about said first aperture in said first housing, and wherein the compressed air is discharged from said first nozzle through said annular aperture.
