Centrifugal oil separator for removing oil from a waste flowing stream
This patent describes an oil separator for removing oil from a flowing waste stream of wast fluid. It comprises: a separator body having a flow bore with a center, and open bottom and an open top each communicating with the flow bore so that fluid can flow in the flow bore between the open botton and the open top; a plurality of vanes, each defining a spiral path for fluid flowing in the bore between the open bottom to the open top, the vanes being spaced radially from the center of the bore and each vane having upper and lower end portions; each vane having a surface to which oil particles can adhere and coalesce as the oil particles travel upwardly thereupon; the vanes being positioned in the bore with the upper and lower end portions of each vane communicating respectively with the bore open top and the bore open bottom portions; to swirl waste fluid upwardly, creating laminar flow, to centrifugally force the waste fluid outwardly in a direction away from the bore center, and to separate oil particles form the wastewater stream beginning with the vane end portions that receive influent wastewater flow; and means positioned adjacent the bore for separating oil collected and coalesced on the vanes from the wastewater.
