ABSTRACT:
An apparatus for removing solid particles from internal combustion engine exhaust gases is proposed, in which the flow of exhaust gas travels at a high speed of more than 2.5 m/sec through an elongated tube (4), in which a corona discharge takes place from a coaxial spray disk/electrode arrangement toward the wall of the tube. Inside the tube, the soot particles are agglomerated to form larger particles, which are not deposited on the walls because of the high flow speed, which then carries them to a centrifugal precipitator, leading away from which are a tube carrying scrubbed exhaust gas and an outlet having a small quantity of exhaust gas highly enriched with soot. This soot-enriched flow of exhaust gas can advantageously be recirculated to the intake side of the associated engine for afterburning.
