ABSTRACT:
A gravity separator for separating two immiscible liquids of different specific gravities and particularly for separating oil from water. The separator is composed of a horizontal, generally cylindrical closed vessel and water is pumped into an inlet in the vessel, and clarified water is discharged through an outlet. In addition, an oil drain line is connected to the upper end of the vessel. Located within the vessel is a cylindrical assembly of generally parallel inclined separator plates. The assembly of separator plates is freely positioned within the vessel and means is provided to prevent rotation and axial movement of the plate assembly within the vessel. A liquid level sensor extends downwardly through aligned openings in the assembly plates, and when the oil level reaches a predetermined maximum depth, the sensor actuates a draining system to drain the oil from the vessel. To aid in preventing the water within the vessel from being discharged through the oil drain line, a baffle is located in spaced relation beneath the drain line.
