Patent number: 7413593Abstract: A gas separation apparatus using electrostatic precipitators and mechanical rappers is enhanced by the addition of an opposite polarity refreshing power supply and a switching arrangement. The switching components selectively disconnect the primary power supply and connect the refreshing power supply to the electrostatic precipitator, causing an electrical impulse in the precipitator sufficient to dislodge precipitate from the collector plates. In one embodiment, an RC filter is further provided to control the impulse and reduce the burden that would otherwise be placed upon the refreshing power supply. In a second embodiment, a pair of SCR strings serve as the switches. Cleaning power is delivered from a capacitor through one of the SCR strings using a resonant circuit, the resonance which causes the SCR string to commutate off after the impulse has been delivered.Type: GrantFiled: January 24, 2006Date of Patent: August 19, 2008Assignee: Electric Power Research Institute, Inc.Inventors: Ralph F.

Patent number: 7311887Abstract: A process reduces SOx emissions in a flue gas stream by adding a wet collector plate section to an existing electrostatic precipitator (ESP) or by converting the last field of an existing ESP to wet operation. To achieve the conversion, the last field or fields of an existing dry ESP are removed and replaced with components made from materials suitable for operation in a wet environment.
