US Patent:

20140059985, Mar 6, 2014
Filed:

Aug 27, 2013
Appl. No.:

14/010730
Inventors:

Benjamin L. Scheckel - Stoughton WI, US
Ashwin K. Koleshwar - Stoughton WI, US
Lee A. Peck - Stoughton WI, US
Saru Dawar - McFarland WI, US
Assignee:

CUMMINS FILTRATION IP, INC. - Columbus IN
International Classification:

B01D 45/16
US Classification:

554594
Abstract:

A gas-liquid separator has a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A nozzle structure in the housing has a plurality of nozzles that receive the gas-liquid stream and accelerate the gas-liquid stream therethrough to create a plurality of gas-liquid jets. An inertial collector in the housing causes a sharp directional change of the gas-liquid jets, causing separation of liquid particles from the gas-liquid stream to produce the gas stream. The inertial collector has a porous collection substrate. According to the present disclosure, at least one of the following three conditions is met: (a) the porous collection substrate comprises fibers of small diameter and has low packing density: (b) the porous collection substrate comprises oleophobic fibers; and (c) the nozzle structure and the inertial collector are configured to allow for full expansion of the plurality of gas-liquid jets.
