1,047,705. Gas washers. AJEM LABORATORIES, Inc. June 4, 1963 [June 4, 1962], No. 22184/63. Heading B1R. A gas washer of the type having a rotating spray generator in the form of a cage 30 has a hollow frusto-conical pump body 34 secured to a ring 33 at the base of the cage, at least the lower end of the body 34 dipping into washing liquid in the base of the washer housing. The connection between the pump body and the cage may be substantially fluid-tight and the body may be cylindrical or bowl-shaped. Impeller vanes may be arranged on the internal surface of the pump body and in some modification (Figs. 4 and 5 not shown) stationary vanes are provided on a rod extending upwardly from the base of the washer housing into the mouth of the pump body.
Abstract:
An in-bed burner system and arrangement for stack furnaces wherein a series of burners are mounted on the stack below the charge door opening to direct a jet of burning gases into the stack below the top surface of the charge bed. Supplementary air is supplied to the stack from a position adjacent the burners to support relatively complete combustion of the products of combustion rising in the stack. Oxygen can augment or replace the supplementary air. The in-bed burners and supplementary air effect burnout of carbon monoxide in the stack exhaust gases and maintain a relatively high temperature in the top portions of the charged bed to thermally crack and burn out organic materials present in the charge.
Abstract:
A segmentally directed rotary spray generator for creating a high-velocity intense liquid spray having a definite arcuate shape with a relatively substantial effective depth useful with air pollution control equipment. The rotary spray generator having a plurality of blades symmetrically arranged radially on a rotatable ring support structure and a liquid supply pipe fitting within the ring structure having an angular orifice opening approximately equal to the angular segment of the spray to be generated.

1,021,573. Gas-scrubbers; spray-producers. AJEM LABORATORIES Inc. Oct. 15, 1962 [Oct. 16, 1961], No. 38938/62. Headings B1R and B2F. In a gas-scrubber a stream of gas enters through an inlet 14 and passes upwardly through a funnel-shaped passage 16 where it is sprayed with spray generated by a rotating cage 24 supplied with liquid by an impeller 62 rotating within a tube 84 with an outwardly flared upper section 92 and with its lower end immersed in the liquid in the bottom of the scrubber, the impeller having a frusto-conical hub 62 with helical blades 68. The pitch of the blades increases upwardly and bends in the lower portions of the blades may be provided to increase the pitch sharply. In a modification the hub of the impeller may be cylindrical and in this case the lower portion of the tube 84 may be downwardly and outwardly flared. The position of the upper section 92 may be adjusted.
