Abstract: A compact, hybrid particulate and gas collector that can be used in an ultra-clean air purification, 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 such as in clean rooms and surgical suites. 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 ultra-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 of the device may be used. Further treatment of the dust free flow with ultraviolet light, an x-ray or a radiation can be used to kill micro-organisms.

Abstract: A multi-stage collector of the type used to collect particles from industrial gas. The collector can contain multiple narrow and wide zones formed by a plurality of parallel corrugated plates. Contained in the narrow zones can be elongated electrodes with sharp leading and/or trailing edges. These electrodes can provide a non-uniform electric field near their sharp edges leading to corona discharge. The corona discharge causes particulate matter in the gas flow to become charged. The region in narrow zones away from the sharp edges of the electrodes resembles a parallel plate capacitor with relatively uniform electric field. In this region, particles can be collected on the plates and on the electrode. Wide regions can contain barrier filters (bag filters) with conductive surfaces. The collector can also be used to clean inlet gas in gasification plants and to collect re-usable materials from a gas stream.

Abstract: A hybrid wet electrostatic precipitator for collecting sub-micron and nano-particulate material. The collector can be made up of three concentric tubes or pipes with an internally formed gas path communicating between an inlet and an outlet. A first collector and discharging zone can be provided in the gas path to create a corona discharge to charge particles and to collect particulate. A second collector can be formed by a porous wall which can act as a filtration device. A third collector can be formed by two or more of the concentric circular tubes, one porous and one solid, with a zone of uniform electric field between them. The porous tube can be either the inner tube or the middle tube. A liquid pool can be placed between the first and third collectors to provide chemical treatment of the gas flow or simply filtration as the gas passes through. A high-tension voltage supply can be used to supply a discharge voltage capable of generating a corona discharge into the flow in the first zone. The corona discharge can cause the fine particulate to become charged and to be captured on the collecting electrode in a zone of uniform field. A second (or the same) high-tension voltage supply can create the uniform electric field.

Abstract: A system for enhancing the efficiency of an electrostatic precipitator in a flue gas stream that withdraws a selected amount of combustion gas from a main flue gas stream at a location downstream of the electrostatic precipitator; typically heats the selected amount of combustion gas to a predetermined temperature; passes the selected amount of combustion gas through a catalyst to convert sulfur dioxide to sulfur trioxide producing a mixture of flue gas enriched with sulfur trioxide; and returns the mixture of the flue gas enriched with the sulfur trioxide back into the main flue gas stream at a point upstream of the electrostatic precipitator. A controller can control fans, heaters and dampers as well as make computations as the required amount of sulfur trioxide needed.

Abstract: A multi-stage collector for multi-pollutant control that contains alternating narrow and wide sections with glow discharge electrodes in some narrow sections, a uniform electric field in wide sections for collecting particles charged by the glow discharge and streamer discharge electrodes in wide or narrow sections that convert and destroy harmful gaseous pollutants such as SO2, NOx and volatile organic compounds as well as convert heavy metals such as mercury into a particulate form. Steady state streamer discharge is supported by non-pulsed power supply. The streaming discharge can convert the polluting gases into nitric and sulfuric acid which can be removed by combining it with ammonia to form solid salts.

Abstract: An FGC conditioning agent injection-control system, where conditioning agent over- or under-injection can be prevented while maximizing a precipitator's performance. The injection rate is typically regulated using feed forward signal proportional to the coal flow, which could be represented by the boiler load augmented by a feedback from the voltage control and electrical conditions in the ESP, sulfur dioxide emissions signaling any changes in the coal quality, opacity monitor data, and other parameters. Both the feed forward and the feedback information and signals from the existing injection skids are analyzed, and the optimal injection rate for the current conditions is determined. With fast, continuous and automatic sampling and analysis, the system responds quickly as each parameter changes, recalculating the optimal injection rate and automatically sends the new injection set-point to the injection skid.
