Abstract
An apparatus for removing soot from an exhaust gas stream wherein the exhaust gas stream is contacted with water to provide a substantially water saturated exhaust gas stream, particles and droplets in the water saturated gas stream then are electrically charged to produce a gas stream containing electrically charged particles and droplets, and an electric field is established for electrostatically attracting and de-entraining soot and soot containing water droplets from the gas stream containing electrically charged particles and droplets to provide a substantially soot free exhaust gas stream. The present invention includes a precipitator wherein the insulators are positioned in low dew point relatively clean locations and, in one embodiment, includes the use of the exhaust gas stream to maintain the temperature level of the insulators above dew point. In one other embodiment, the condensate produced as a result of electrostatically attracting and de-entraining soot and soot containing water droplets from the exhaust gas stream containing electrically charged particles and droplets is recirculated and used as part of the water for contacting the exhaust gas stream.
