Title
(EN) REMOVAL OF PARTICULATE MATERIAL
(FR) EXTRACTION DE MATIERES PARTICULAIRES
Abstract
(EN)
Apparatus for removal of particulate material from a gas stream comprises a housing (10) including inlet (11) and an outlet (12) for the fluid stream and means for connection of the housing within pipework containing the stream, means (13) for generating a rotary motion in the fluid within the housing, an expansion chamber (15) disposed downstream of the rotary motion generating means, and a collection chamber (16) whereby, in use with particulate-containing fluids flowing through the device, a rotary motion is imparted in the fluid by the rotary motion generating means, the fluid being decelerated in the expansion chamber with precipitation of particulates towards the periphery thereof, the fluid stream with particulates removed therefrom passing from the housing through the outlet, and precipitated particulates being collected in the collection chamber.
(FR)
Appareil destiné à l'extraction de matières particulaires d'un flux de gaz, qui est constituée d'une enceinte (10) comprenant un orifice d'admission (11) et un orifice de sortie (12) pour le flux ainsi qu'un moyen de raccordement de l'enceinte à l'intérieur de la tuyauterie renfermant le flux, un dispositif (13) permettant d'imprimer un mouvement de rotation au fluide dans l'enceinte, une chambre de détente (15) placée en aval du générateur de rotation et une chambre de réception (16). Lorsque des fluides chargés de particules circulent dans l'appareil, un mouvement de rotation est imprimé au fluide au moyen d'un générateur de rotation, puis le fluide est soumis à un ralentissement dans la chambre de détente, ce qui provoque la séparation par précipitation des particules vers sa périphérie. Le flux exempt de particules passe de l'enceinte à l'orifice de sortie et les particules précipitées sont recueillies dans la chambre de réception.
