ABSTRACT:
Apparatus for precipitating dust from a region surrounding an area from which dust emanates. The apparatus includes a fluid supply conduit for carrying water under pressure to the region adjacent the dust, area, a proportioning pump for injecting a preselected quantity of a surfactant into the water, and nozzles on the conduit adjacent the dust emanating region. The mixture of water and surfactant is atomized and sprayed from the nozzles in a curtain of finely dispersed spray, or fog, adjacent the dust region. The substantially continuous curtain of finely dispersed spray surrounding the dust region acts to precipitate dust particles from the air. The mixture of a surfactant with the water allows the water to easily wet the dust particles, whereby smaller quantities of water may be used with improved dust precipitation occurring.
