Title (EN) METHOD AND ARRANGEMENT FOR REMOVING PARTICLES FROM EXHAUST GAS
(FR) PROCÉDÉ ET AGENCEMENT POUR LA SUPPRESSION DES PARTICULES DANS 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 from the exhaust gas, water super saturation is provided in the exhaust gas particle cleaning device. The exhaust gas particle cleaning device is provided with a higher temperature section and a lower temperature section causing particle growth at the lower temperature section.
(FR) L'invention porte sur un procédé de suppression des particules dans un gaz d'échappement d'un écoulement de gaz d'échappement d'un moteur à combustion interne (1). Le gaz d'échappement provenant du moteur à combustion interne (1) est amené vers un dispositif de nettoyage de particules de gaz d'échappement (9). Dans le but de permettre une suppression efficace des particules dans le gaz d'échappement, on délivre une sursaturation d'eau dans le dispositif de nettoyage de particules de gaz d'échappement. Le dispositif de nettoyage de particules de gaz d'échappement comporte une section à température supérieure et une section à température inférieure, amenant la croissance des particules dans la section à température inférieure.
