Definitions

  • the apparatus according to the second aspect of the invention is modified according to the first aspect of the invention.
  • the pump 12 serves to compress the agglomerated particulate in sac 18.
  • the agglomerated particulate has the consistency and viscosity of a thick (relative to water) liquid and can be pumped adequately by a relatively low power pump.

Abstract

L'invention concerne un appareil destiné au transfert des particules contenues dans des flux d'échappement. L'appareil comprend une voie d'écoulement du flux d'échappement, un système (34) pour charger au moins certaines particules à l'intérieur du flux d'échappement et un système (4) pour focaliser au moins certaines des particules chargées.
