ABSTRACT:
A wet dust collecting and filtration system incorporates an upright settling tank in the bottom of which is formed a pool of water at a defined level. The dust carrying air is supplied to the tank through an air transfer pipe under pressure supplied by a blower which is mounted on the same portable cart as the settling tank. Connected to the air inlet that receives the air from the transfer pipe is an "L" shaped pipe that extends down from the dirty air inlet and terminates in a conical funnel ending below the surface of the water pool. The water is supplied under significant pressure so that an envelope of water is formed that seals the top of the pool of water against the edges of the funnel. The resulting scrubbing action of the air causes precipitation of the dirt, dust and soot which is carried into the air into the water. The precipitates sink toward the bottom of the pool while the air itself flows up out of the water to be withdrawn from the top of the tank. In a preferred embodiment, a secondary dry element filter is supported at the top of the tank through which the air is withdrawn, the presence of this filter element preventing the water from spraying out the top of the tank, refiltering the air before final exhausting to atmosphere.
