Device for removing oil, etc from sea water, etc includes partially immersed rotatable volume of circular cross section entraining oil and discharging it into air

摘要

A device for separating two at least partly immiscible liquids of different density and viscosity includes a partially immersed rotatable volume of circular cross section. It displaces the surface of the complex liquid and entrains the uppermost of the two liquids. This liquid forms a coating on the surface of the volume and then is discharged into the air. The volume may be a roller or a belt arranged around two rollers. The volume may have spaced planar layers arranged perpendicular to the rotation axis. Their spacing on the viscosity and the capillarity of the liquid. The immersion of the volume depends on the thickness of the upper liquid layer and the diameter of the volume. The liquid coating the volume is removed by a scraper and/or compressed air jet.
