Title (EN) A SCRUBBER FOR CLEANING OF A GAS
(FR) ÉPURATEUR POUR LE NETTOYAGE D'UN GAZ
Abstract:
(EN) A scrubber (1) for cleaning of a gas comprises a casing (3) extending along a longitudinal central axis (x) and enclosing a scrubbing chamber (4). The casing has a gas inlet (5) and a gas outlet. The casing is configured to permit a gas flow of the gas to flow through the scrubbing chamber in a flow direction (F) from the gas inlet to the gas outlet. A deflector device (12) is provided in the scrubbing chamber between the gas inlet and the gas outlet and forms a gas passage (28) between the deflector device (12) and the casing (3). The deflector device comprises an upstream surface (16) facing the gas inlet. A spraying nozzle (8) is configured to spray a scrubbing liquid into the scrubbing chamber and the gas flow. A separation device (40) comprises a shield element (41) and is arranged between the upstream surface of the deflector device and the gas inlet. The shield element shields the upstream surface from the gas flow and is perforated by a plurality of holes.
(FR) Un épurateur (1) pour le nettoyage d'un gaz comprend un boîtier (3) s'étendant le long d'un axe central longitudinal (x) et renfermant une chambre de lavage (4). Le boîtier comprend une entrée de gaz (5) et une sortie de gaz. Le boîtier est configuré pour permettre à un écoulement de gaz du gaz de s'écouler à travers la chambre de lavage dans une direction d'écoulement (F) de l'entrée de gaz à la sortie de gaz. Un dispositif déflecteur (12) est disposé dans la chambre de lavage entre l'entrée de gaz et la sortie de gaz et forme un passage de gaz (28) entre le dispositif déflecteur (12) et le boîtier (3). Le dispositif déflecteur comprend une surface amont (16) faisant face à l'entrée de gaz. Une buse de pulvérisation (8) est configurée pour pulvériser un liquide de lavage dans la chambre de lavage et l'écoulement de gaz. Un dispositif de séparation (40) comprend un élément de protection (41) et est disposé entre la surface amont du dispositif déflecteur et l'entrée de gaz. L'élément de protection protège la surface amont de l'écoulement de gaz et est perforé par une pluralité de trous.
