Wet dust suppression floor cleaning system

摘要

An arrangement for removing dust from the atmosphere during cleaning of a generally flat surface, such as floor, includes a reservoir for providing water to a nozzle. Also included is an air compressor and a compressed air tank. Compressed air is provided in a controlled manner at an elevated pressure to the nozzle to reduce the water to minute droplets which absorb/encapsulate the dust particles and deposit them on the floor surface under the influence of gravity. A manual or automatic pressure regulator coupled to the outlet of the compressed air tank allows for selecting the air velocity and the size of the water droplets to match the size of the dust particles to increase the extent of dust removal. This dust removal approach can be used with virtually any type of generally flat surface and the compressed air has a siphoning effect to increase the water droplets produced and the dust particles removed.

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.
