Abstract
PURPOSE: To miniaturize the apparatus and make it higher in performance by forcefully supplying dust-laden gas or the like by way of a dust scrubbing and collecting mechanism, a classifying and collecting mechanism, a classifying and capturing mechanism constituted by fog rings, a water film dust collecting mechanism and an eliminator mechanism.
CONSTITUTION: The dust particles in the dust-laden gas G entered into a dust collecting and sucking hood 1 by the suction force of an axial-flow fan E are captured and removed stepwise by passing a dust scrubbing and collecting mechanism A, a classifying and capturing mechanism B, a water film dust collecting mechanism C and an eliminator mechanism D, respectively. The clean air is exhausted into the atmosphere by a fan E. At this time, the dust-laden gas G reached the classifying and capturing mechanism B is diffused by fog rings 6 and is striken to a liquid surface 8a. Becasue of this, the relatively coarse dust particles in the dust-laden gas G colliding against the liquid surface 8a is captured with good efficiency by the continuous capturing action by the waving of the liquid surface 8a.
