초록 ▼

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.

I claim: 1. A compact hybrid collector system comprising: a first region containing a high-tension corona discharge; a second region separated from said first region containing a first high-tension substantially constant electric field; a third region separated from said second region by a porous surface, said third region containing a second high-tension substantially uniform electric field; wherein gas flow enters said first region where particles in said gas flow become charged by said corona discharge; and wherein said gas flow enters said second region where particles in said gas are removed by said first high-tension electric field, and wherein said gas flow passes through said porous surface into said third region where particles are removed by said second high-tension electric field. 2. The compact hybrid collector system of claim 1 wherein said porous surface is coated with a catalyst. 3. The compact hybrid collector system of claim 1 wherein said first, second and third regions are cylindrically shaped. 4. The compact hybrid collector system of claim 1 further comprising a central electrode with discharge points for forming said corona discharge. 5. The compact hybrid collector system of claim 1 wherein said central electrode is grounded. 6. The compact hybrid collector system of claim 5 wherein said porous surface is raised to a high electric potential with respect to said central electrode. 7. The compact hybrid collector system of claim 1 further comprising an enclosure containing said system made of a material selected from the group consisting of metal, plastic and ceramic. 8. The compact hybrid collector system of claim 1 further comprising a dielectric barrier discharge in said second region. 9. The compact hybrid collector system of claim 1 further comprising a plurality of first and second regions operated in parallel. 10. A hybrid collector system comprising a first region where a gas flow passes through a plurality of corona discharges, a second region where said gas flow passes through a first substantially uniform electric field and a third region where said gas flow passes through a second substantially uniform electric field, and wherein said second and third regions are separated by a porous surface. 11. The hybrid collector system of claim 10 wherein said porous surface is coated with a catalyst. 12. The hybrid collector system of claim 10 further comprising a dielectric barrier discharge region in said second or third regions.
