20090151568 | Space efficient hybrid collector - A compact, hybrid particulate and gas collector that can be used in a vehicle emissions control system, gas turbine, or in any other application where space and lower cost is important or in applications where sub-micron and nano-particulate filtering is needed. A gas flow enters the device in a first chamber and can be immediately exposed to a high-tension corona discharge electric field which typically results in a strong ionic flow by charging and collecting the incoming effluent (oil mist, soot particles, etc.). Subsequently, the charged flow enters a second zone of high-tension uniform electric field that causes the remaining charged particles to migrate to one of the charged electrodes. One of the electrodes can be made of porous filter material that allows the cleaned gas to flow into an exit zone also containing a high-tension uniform electric field where the remaining effluent can be collected prior to the clean gas exiting either to ambient air or being re-circulated to be used again by the engine. In some embodiments a dielectric barrier discharge surface can be provided to convert harmful compounds to more desirable substances. Alternate embodiments can include a third zone containing a second substantially uniform electric field as well as coating the porous surface with a catalyst to convert undesirable compounds. Any cross-section may be used. | 06-18-2009 |
