Abstract
Abstract A gas scrubber and purifier for the exhaust gases from incinerators, furnaces and the like, the exhaust gases being forcibly passed through water curtains and sprays produced by revolving discs which throw water by centrifugal force through which the exhaust gases are forced to pass to capture any fine solid matter such as dust, fly ash and the like and to dissolve any soluble gaseous ingredient in the exhaust gases.

Claim 1
Independent Claim
408 words
An improvement in an exhaust gas scrubber system comprising: a. a plurality of vertical supported elongated cylindrical chambers arranged in relatively close relationship, each of said chambers having a gas inlet and gas outlet openings; b. gas conveying ducts connecting the inlet and outlet openings of the several chambers in series whereby gas passing out of one chamber is introduced into the inlet opening in another chamber, the inlet opening in the first chamber in the series operating to receive the gas to be scrubbed, and the outlet in the last chamber in the series operating to release the gas from the scrubber; c. a plurality of individual freely rotatable circular discs positioned in each of the chambers and spaced apart one above the other in each of the said chambers, supporting means for supporting said rotatable discs in a vertical axis within a predetermined location within each of the said chambers, each of the said discs being tapered downwardly and outwardly toward its outer edge, said discs being mounted in a plane perpendicular to the vertical axis of the chamber and having a diameter slightly less than the inside diameter of the circular chamber thereby allowing a uniform narrow space between the outer peripheral edge of the disc and the inner side of the chamber as the discs are rotated, the area of the space between the periphery of the several discs and the inner side Of the chamber being such as to readily accommodate the gas passing upwardly through the scrubber; d. a plurality of upstanding fins positioned on the upper side of each of the said discs and adjacent at least the peripheral edge thereof; e. a plurality of stationary water supply means for supplying water under pressure located adjacent and above each of the discs and positioned to direct a stream of water under pressure against the corresponding sides of the fins on each alternate disc for rotating each disc in the same direction, and a plurality of stationary water supply means for supplying water under pressure located adjacent and above each of the remaining discs to direct a stream of water under pressure against the opposite sides of the fins of the remaining discs for rotating the same in a direction opposite the rotation of the firstmentioned discs; f. the water supply means positioned to rotate each disc in a predetermined direction; g. means provided for circulating the gas through the said scrubber.
