An apparatus is disclosed for reducing pressure and velocity of a particulate- laden, supersonic vent gas stream from a pressure vessel such as an autoclave. The apparatus includes a diverging duct in which the vent gas expands, and a perfo-rated plate located inside the diverging duct. The perforated plate provides an area reduction that increases back pressure and forces an upstream normal shock in the diverging duct, thereby bringing about a desired reduction in pressure and velocity. The perforated plate is comprised of a material, such as a ceramic, that is resistant to erosion by the abrasive particulate entrained in the high velocity vent gas. The perforated plate has a central portion provided with holes and an imperforate peripheral portion which is resiliently received between connection flanges of the duct.
L'invention concerne un dispositif conçu pour réduire la pression et la vitesse d'un flux de gaz d'évacuation supersonique chargé en particules d'une cuve sous pression telle qu'un autoclave. Le dispositif comprend une conduite divergente dans laquelle le gaz d'évacuation se dilate, et une plaque perforée placée à l'intérieur de la conduite divergente. La plaque perforée comprend une réduction de zone qui augmente la contre-pression de refoulement et provoque un impact normal en amont dans la conduite divergente, entraînant ainsi une réduction souhaitée dans la pression et la vitesse. La plaque perforée est composée d'un matériau, tel qu'une céramique, qui résiste à l'érosion par les particules abrasives entraînées dans le gaz d'évacuation à grande vitesse. La plaque perforée comprend une partie centrale dotée de trous et une partie périphérique non perforée qui est reçue de façon résiliente entre les brides de raccordement de la conduite.
