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) enclosing a scrubbing chamber (4). The casing comprises a gas inlet (5) into and a gas outlet (6) out from the scrubbing chamber. A gas flow of the gas flows through the scrubbing chamber in a flow direction (F) from the gas inlet to the gas outlet. A deflector device (11) is provided in the scrubbing chamber between the gas inlet and the gas outlet and forms a passage (28) between the deflector device and the casing. A spraying nozzle (8) is arranged between the gas outlet and the deflector device for spraying a scrubbing liquid into the scrubbing chamber and the gas flow. An inner shield (20) extends between the casing and the deflector device, surrounds the deflector device (11) at least partly, and forms a gap (21) with the casing. Scrubbing liquid may flow through the gap.
(FR) Un épurateur (1) pour le nettoyage d'un gaz qui comprend un boîtier (3) renfermant une chambre de lavage (4). Le boîtier comprend une entrée (5) et une sortie de gaz (6) hors de la chambre de lavage. Un débit gazeux s'écoule à travers la chambre de lavage dans un sens d'écoulement (F) de l'entrée à la sortie de gaz. Un dispositif déflecteur (11) est prévu dans la chambre de lavage, entre l'entrée et la sortie de gaz, et crée un passage (28) entre le dispositif déflecteur et le boîtier. Une buse de pulvérisation (8) est située entre la sortie de gaz et le dispositif déflecteur pour pulvériser un liquide de lavage dans la chambre de lavage et le débit gazeux. Un écran interne (20) est situé entre le boîtier et le dispositif déflecteur, entoure le dispositif déflecteur (11), au moins partiellement, et crée un espace (21) avec le boîtier. Le liquide de lavage peut s'écouler à travers cet espace.
