Patent number: 7799109Abstract: The invention relates to a device for separating a gas-liquid mixture, in which the liquid portion exists in the form of small particles, especially for ventilating a crankcase of an internal combustion engine, by separating and coagulating the liquid particles on a target area. The liquid mixture, after acceleration in acceleration openings provided for this purpose, impacts the target area at an approximately right angle. The aim of the invention is to improve the aforementioned device in such a manner that it allows as high a degree of separation as possible for different sized volume flows of mixtures. For this purpose, the number and/or the cross-sections of the acceleration openings is varied, depending on the volume flow of mixtures, between a small complete cross-section for a low volume flow and a large complete cross-section for a large volume flow.Type: GrantFiled: May 29, 2006Date of Patent: September 21, 2010Assignee: MAHLE International GmbHInventors: Robert Dunsch, Andreas Enderich, Leszek Goerlich, Stefan Ruppel, Yakup Ă–zkaya

Publication number: 20100229727Abstract: A system for reducing the occurrence of fires in a fabric filter dust collection system. The system includes an elongated housing having a first end and a second end distal from the first end. A gas flow inlet is provided in flow communication with an interior portion of the housing for flow of gas and particulates from a source into the housing. A gas flow outlet is provided in flow communication with the housing for flow of gas and particulates out of the housing and into the dust collection system. An elongated spark arrestor is disposed in the housing between the first end and the second end. The spark arrestor has a plurality of spaced-apart, wedge-shaped members having a gap between adjacent members sufficient to interrupt the flow of combustible particles from the source to the dust collection system.Type: ApplicationFiled: March 13, 2009Publication date: September 16, 2010Applicant: SUNCOKE ENERGY, INC.Inventor: Michael P. BARKDOLL
