OXYGEN DISSOLVER FOR PIPELINES OR PIPE OUTLETS

摘要

An apparatus for dispersing a gas into a fluid stream. The apparatus comprises a generally annular body disposed to define an orifice in the flui d stream, a plurality of inwardly depending apertures formed in the body and i n fluid communication with a supply of pressurized gas. Each of said apertures defines a localized injection point for dispersion of the pressurized gas in to the fluid stream. The orifice includes a restricted throat section adapted progressively to reduce the effective cross-sectional flow area of the fluid downstream of said apertures, such that resultant velocity and pressure differentials enhance dissolution of the gas in the fluid.
