Abstract

Abstract 1,160,578. Gas cleaner. NATIONAL DUST COLLECTOR CORP. 28 Oct., 1966 [10 Nov., 1965], No. 48478/66. Heading B1R. Gas to be cleaned is passed upwardly in a housing 14 and through openings 62a in a plate 62 and tapering nozzles 66 curved at their upper ends so that the streams of gas and entrained liquid issuing therefrom collide, liquid being introduced into the nozzles through rows of openings 68a (Fig. 5, not shown) and 70a (Figure 2, not shown) near their lower ends from a bath of liquid surrounding the nozzles. The amount of liquid supplied from the liquid bath may be controlled by varying the height of the liquid in the bath. The rows of openings 68a and 70a are closed by flexible plates when no gas is flowing through the nozzles: Liquid is also sprayed into the gas to be cleaned by sprays 76 and a filter bed 98 may be arranged above the upper ends of the nozzles 66 to remove liquid from the cleansed gas.
