ABSTRACT:
A flow-through coalescing separator applicable to clean immiscible liquids and to dirt-carrying immiscible liquids, such as dirty oil and water mixtures. A normally retracted piston periodically backwashes and thereupon compresses the filter body in a pressure vessel so as to purge the filter body of accumulations of dirt and hydrocarbons. When the piston is thereafter being retracted by restoration of input liquid flow pressure, positive coupling of the piston to the filter body stretches it back to its original length and thereby to the full functioning open-pore condition despite wall friction and limited rebound capability of the filter body material. The system lends itself to manually controlled operation and to automatically controlled operation, either in the continuous flow-through mode or in the more frequently interrupted retention flow-through mode. In either mode the system provides predictably-metered backwash liquid volume determined by pressure vessel capacity from its input chamber to the working face of the piston.
