a gravity separator functioning and depression for mixtures of two liquids do not mix.

摘要

A separator suitable for the separation of a first liquid of relatively lower specific gravity and a second liquid of relatively higher specific gravity from a liquid mixture containing both liquids, the liquids being mutually immiscible, the separator comprising an inlet for introducing the mixture into a first separation zone so constructed and arranged as to promote the separation by gravity of a substantial part of the first liquid from the mixture, a first liquid outlet for the discharge of separated first liquid from the separator, a second liquid outlet for the discharge of separated second liquid from the separator, means for causing first liquid separated in the first separation zone to pass to the first liquid outlet, means for causing the remaining liquid mixture containing a minor proportion of the first liquid and a major proportion of the second liquid to pass towards the second liquid outlet along a flow path including a part extending downwardly through a second separation zone partially filled with a liquid-permeable bed of powdered filter material which is active for retaining and coalescing droplets of the first liquid, and means for causing the resulting liquid to pass from the bottom of the liquid-permeable bed to the second liquid outlet.
