(EN) GAS DISPERSER FOR GUIDING GAS INTO A CHAMBER, SPRAY DRYING APPARATUS COMPRISING SUCH A GAS DISPERSER, AND METHOD OF ALIGNING A STREAM OF GAS IN A GAS DISPERSER
(FR) DISPERSEUR DE GAZ POUR GUIDER UN GAZ DANS UNE CHAMBRE, APPAREIL DE SÉCHAGE PAR PULVÉRISATION COMPRENANT UN TEL DISPERSEUR DE GAZ, ET PROCÉDÉ D'ALIGNEMENT D'UN FLUX DE GAZ DANS UN DISPERSEUR DE GAZ
Abstract
(EN)
In the gas disperser (3), a flow conditioning device (5, 6) is located in the inlet duct section (32). The flow conditioning device comprises a hole plate (5) and a flow straightener (6) positioned in parallel with and at a distance (h) in the axial direction (axd) from the downstream side of the hole plate (5). The hole plate (5) has a predefined hole plate thickness (tp) in the axial direction (axd) and each flow straightener (6) has a predefined flow straightener length (Is) in the axial direction (axd), the flow straightener length (Is) being substantially larger than the hole plate thickness (tp).
(FR)
Dans le disperseur de gaz (3), un dispositif de conditionnement d'écoulement (5, 6) est situé dans la section de conduit d'entrée (32). Le dispositif de conditionnement d'écoulement comprend une plaque à trous (5) et un redresseur d'écoulement (6) positionné en parallèle avec et à une distance (h) dans la direction axiale (axd) depuis le côté aval de la plaque à trous (5). La plaque à trous (5) a une épaisseur de plaque à trous (tp) prédéfinie dans la direction axiale (axd) et chaque redresseur d'écoulement (6) a une longueur de redresseur d'écoulement prédéfinie (Is) dans la direction axiale (axd), la longueur de redresseur d'écoulement (Is) étant sensiblement supérieure à l'épaisseur de plaque à trous (tp).
