Abstract
This invention provides a separator for two relatively insoluble mixed liquids of different specific gravities as, for example oil and water. More particularly the invention relates to a bilge oil separating system (BOSS), or apparatus and includes a float controlled bilge pump for pumping the oil contaminated bilge water from a ship's bilge into a splatter chamber, that, to considerable measure, undoes the globularization of the oil caused by the bilge pump. This is effected by changing the rather rapid downward flow of the mixed liquids out of the delivery tube to a hollow jet type outwardly and upwardly directed flow that then changes to a hollow cylindrical downward flow against the inner cylindrical surface of the wall of a splatter chamber. The oil, after the globules are thus coalesced, moves with the water down into diffuser which serves the liquid to the bottom of an obliquely upwardly extending channel provided internally with downwardly projecting baffles to collect the oil in pockets at the ceiling of the channel to effect gravitational separation of the two liquids and to dampen out any sloshing about of the two-phase liquid. The channel delivers the liquid to the top …
