Problems solved by technology

Increased Liquid Carryover of Rotary Coalescers May Reduce Filtration System Efficiency
Additionally, due to the direct ejection of coalesced droplets towards the outlet, increased liquid carryover can make it difficult to position the airflow outlet of the coalescer housing directly opposite the outer diameter of the rotating coalescer

Embodiment Construction

[0018] Referring generally to the drawings, a rotary coalescer with a jet coalescing liquid separation device is described. The separation device prevents re-entrainment of liquid into the already filtered gas stream. A rotary coalescer includes a rotary filter element or coalescer cone stack positioned within a rotary coalescer housing. The outer surface (ie, clean side) of the rotating filter element or the outlet of the coalescing cone plate stack is moved away from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or stack of coalescing cone plates and the rotating coalescer housing allows coalescing liquid, such as a spray of oil, to accumulate on the inner surface of the rotating coalescer housing for drainage, and to allow filtration The gas (such as air) is discharged through the clean gas outlet of the rotating coalescer shell. In some arrangements, the rotating coalescer housing includes fins that prevent accumulated l...

Abstract

A rotary coalescer with a jet coalescing liquid separation device is described. The separation device prevents re-entrainment of liquid into the filtered gas stream. The rotary coalescer includes a rotary filter element or coalescing cone plate pack positioned within a rotary coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or stack of coalescing cone plates and the rotating coalescer housing allows coalescing liquid, such as a spray of oil, to accumulate on the inner surface of the rotating coalescer housing shell for drainage and allows Filtered gas, such as air, is exhausted through the clean gas outlet of the rotary coalescing shell.

Description

[0001] Cross References to Related Applications [0002] This application claims application number 62 / 211,538, filed August 28, 2015, by Schwandt et al., entitled "ROTATING COALESCINGELEMENT WITH DIRECTED LIQUID DRAINAGE AND GAS OUTLET), the contents of which are hereby incorporated by reference in their entirety for all purposes. technical field [0003] This application relates to rotating coalescing elements. Background technique [0004] During operation of the internal combustion engine, part of the combustion gases can flow out of the combustion cylinder and into the crankcase of the engine. These gases are commonly referred to as "blowby" gases. Blowby gases include a mixture of aerosols, oil, and air. Blowby gases can be hazardous to the environment if they are released directly into the environment. Accordingly, blowby gases are typically exhausted from the crankcase through the crankcase ventilation system. The crankcase ventilation system may pass the blowby...
