摘要： A pollutant destruction system connects a capacitive corona discharge chamber in a self-resonant circuit with an inductive element. Intermittent energizing signals are furnished from a power supply to induce corona discharges within the chamber, with the resonant circuit responding to the energizing signals by initiating additional corona discharges between energizing signals in a highly energy efficient operation. One or more discharge chambers can be provided in the resonant circuit, with each discharge chamber comprising a dielectric enclosure with a distributed electrode outside and an elongate electrode inside the enclosure. The inner electrode can extend either along the chamber axis, or along the inner chamber wall for better support and heat dissipation. The energizing pulse frequency can be controlled in various ways, such as in response to a termination of corona discharges, an increase in the pollutant concentration or an acceleration of an engine whose exhaust is being treated, or the pulses can be applied at a fixed rate.

摘要： A corona discharge pollutant destruction reactor employs two or more electrodes to enhance the effective corona discharge treatment volume by distributing a varying electric field pattern over the reactor's interior chamber. Appropriate delay circuitry allows the inner electrodes to be driven out of phase with each other by a sinusoidal voltage waveform, or corona producing voltage pulses to be cyclically supplied to the inner electrodes in sequence, preferably without overlapping the pulses.

摘要： Contaminant levels in a fluid such as air or water are reduced by producing a pulsed electron beam having an average primary electron energy of from about 90 to about 110 thousand electron volts (corresponding to an average injected electron energy of from about 45 to about 55 thousand electron volts in a preferred case) and directing the electron beam through the fluid. The contaminant compounds may include organic compounds and certain inorganic compounds such as NO.sub.x and SO.sub.x. The fluid is preferably contained in a contaminant reduction cell that is separated from an electron beam source by an electron-transparent window.

摘要： An exhaust system that processes exhaust generated by an engine includes a diesel particulate filter (DPF) that is disposed downstream of the engine and that filters particulates from the exhaust. An electrical heater is integrally formed in an upstream end of the DPF and selectively heats the exhaust to initiate combustion of the particulates within the exhaust as it passes therethrough. Heat generated by combustion of the particulates induces combustion of particulates within the DPF.

摘要： A diesel particulate filter including a microwave-absorbing target housed within a waveguide cavity lined along the walls with a hard-electromagnetic surface (HES). The HES modifies specific electromagnetic boundary conditions for a given design frequency so as to enable the establishment of electromagnetic field patterns which are more uniform across the cavity thereby causing the target material to undergo enhanced uniformity heating. The heating of the microwave absorbing media causes particulate buildup to be vaporized and removed from the filter by the exhaust stream flow.

摘要： A corona discharge pollutant destruction system has two or more corona discharge reactors in series, with each stage optimized for either oxidation of hydrocarbons (HC) and carbon monoxide (CO) or reduction of nitrogen oxides (NO.sub.x). The reactors may be arranged with initial oxidation stages followed by reduction stages. Alternatively, the oxidation and reduction reactors may be arranged in alternate stages, with each oxidation reactor followed by a reduction reactor. The treatment of different pollutants by different reactors is achieved by supplying the different reactors with different power levels.

摘要： An indoor air pollutant destruction apparatus destroys pollutants by a corona discharge that is generated by a rapidly oscillating electric field. Free electrons generated by the corona discharge produces ozone (O.sub.3), which effectively destroys volatile organic compounds (VOCs) and biological forms such as bacteria, fungi, viruses and spores. Fine particulate materials such as smoke and dust are charged by the corona discharge, and when they pass through the rapidly oscillating electric field, they coagulate to form larger particles which are then filtered out.
