Title (EN) METHOD AND ARRANGEMENT FOR REMOVING PARTICLES FROM EXHAUST GAS
(FR) PROCÉDÉ ET AGENCEMENT PERMETTANT DE SUPPRIMER DES PARTICULES D'UN GAZ D'ÉCHAPPEMENT
Abstract:
(EN) The invention relates to a method for removing particles from exhaust gas from an exhaust gas flow of an internal combustion engine (1). The exhaust gas from an internal combustion engine (1) is led to an exhaust gas particle cleaning device (9). In order to allow for efficient particle removal (4) from the exhaust gas, water supersaturation is provided in the exhaust gas particle cleaning device (9). The exhaust gas particle cleaning device is provided with a low pressure section (3a) and a high pressure section (3b) causing particle growth at the high pressure section (3b).
(FR) La présente invention a trait à un procédé permettant de supprimer des particules d'un gaz d'échappement provenant d'un écoulement de gaz d'échappement d'un moteur à combustion interne (1). Le gaz d'échappement provenant d'un moteur à combustion interne (1) est conduit jusqu'à un dispositif de nettoyage de particules de gaz d'échappement (9). Afin d'obtenir une suppression efficace des particules (4) à partir du gaz d'échappement, une sursaturation de l'eau est fournie dans le dispositif de nettoyage de particules de gaz d'échappement (9). Le dispositif de nettoyage de particules de gaz d'échappement est équipé d'une partie à faible pression (3a) et d'une partie à haute pression (3b) causant la croissance des particules dans la partie à haute pression (3b).
