Abstract

L'invention concerne un appareil de dépoussiérage équipé d'organes destinés à créer des turbulences. L'appareil comporte une enveloppe qui délimite un passage convergent de gaz souillé de poussieres, avec une entrée de gaz à un bout et une sortie des grains de poussière à l'autre bout Une paroi de l'enveloppe est équipée d'auvents qui séparent les grains de poussière du courant gazeux. Une certain nombre de saillies se projettent dans le passage convergent pour créer des turbulences qui atténuent le bruit produit par l'écoulement gazeux. L'invention s'applique en particulier au dépoussiérage de l'air d'admission dans les moteurs Diesel de traction ferroviaireThe invention relates to a dedusting apparatus equipped with members for creating turbulence. The apparatus comprises a casing which delimits a converging passage of gas contaminated with dust, with a gas inlet at one end and an outlet of dust grains at the other end A wall of the casing is equipped with louvers which separate the dust grains of the gas stream. A number of protrusions project into the converging passage to create turbulence which dampens the noise produced by the gas flow. The invention applies in particular to the dusting of the intake air in diesel railway traction engines.
