Abstract:
A process for collecting and handling dust in a papermaking environment comprising the steps of:providing an elongated collector having an inlet, an exit opening and a longitudinal axis;drawing dust-laden air into the inlet of the collector and inducing an air vortex which flows between the inlet and exit opening of the collector wherein the air vortex is centered about the longitudinal axis of the collector and is formed with the dust-laden air drawn into the collector andintroducing water into the collector so that the introduced water wet-scrubs the dust-laden air which enters the collector by colliding with the dust-laden air upon entry of the air into the collector so that the water becomes entrained within the dust-laden air and is carried along the collector with the dust-laden air between the inlet and the exit opening of the collector and so that the dust of the dust-laden air is exposed to and mixes with the water moving along the collector from the moment that the dust-laden air enters the collector until the moment that the air exits the collector through the exit opening.
