Definitions

  • the gas containing soot particles to be cleaned reaches the area of the spray electrodes 11, whereby the soot but also the oxygen present in the gas is electrically charged.
  • 0 2 "radicals are formed.
  • the electrically charged soot subsequently arrives in the channels 7 of the honeycomb filter 1, where it is passed through the electric field in the direction of the walls of the channels 7 of the honeycomb filter 1 which are essentially perpendicular to the electric field Accelerated and deposited on the carbon black
  • the charged oxygen is also accelerated in the direction of the deposited soot. Together with the electrons emerging from the ceramic, this results in an energy input into the deposited soot, so that the carbon black is deposited at a low temperature
  • the combustion is supported by the high willingness of the free 0 2 " radicals to react.

Abstract

Ce filtre à suie comprend au moins un canal dans lequel s'écoule un gaz chargé de suie, délimité par une céramique dont la surface extérieure porte des électrodes à haute tension. Afin de brûler les particules de suie à de basses températures et en sollicitant aussi peu que possible une source d'alimentation des électrodes en tension, la céramique est à base de silicate d'aluminium alcalino-terreux, de silicate d'aluminium ou de silicate de magnésium et d'aluminium. Afin de réduire le travail d'extraction des électrons, la céramique est dopée avec une concentration de 0,05 à 1 % en poids d'au moins un composé métallique du groupe constitué de Ba, Fe, Sr, Nb, Mo, Ti, Co et de préférence V.
