Abstract
Abstract Air contaminated with particles enters an enclosure at relatively high velocity through an inlet passage having a water spray blanket projected thereacross. Within the enclosure, the air impacts against a water pool maintained at a constant level and has its direction of flow changed abruptly thereabove several times by a system of overlapping baffles. Extreme turbulence is induced in this zone and means are provided to induce some recirculation toward the water pool. Substantially cleaned air expands through a moisture eliminator into a drying chamber and discharges through the outlet of a blower which also serves to move the air through the entire apparatus.
