Abstract
An ejector assembly adapted to intermingle a gas, such as chlorine, with process liquid or water to form a solution which is discharged from the assembly. Included in the assembly is an ejector body within which is disposed a nozzle whose output is spaced from the inlet of a throat to define an interaction zone which communicates with a gas supply. Liquid under pressure is fed into the nozzle and is forced thereby at high velocity into the interaction zone to create a vacuum acting to draw gas from the gas supply. The gas interacts with the liquid to form a solution that is discharged via the throat through suitable piping to a point of application. Coaxially disposed within the contoured bore of the nozzle is a plug which defines an annular liquid flow path, the plug having an enlarged flange thereon which cooperates with the contoured bore to form alternate restrictions and expansions in the flow path that render the liquid highly turbulent and produce cavitation, thereby enhancing the interaction of liquid and gas in the interaction zone to provide a higher vacuum level of operation to permit critical flow control at no additional cost.
