Title (EN) METHOD FOR CLEANING LIQUID EFFLUENTS OF A WET SCRUBBER TREATING EXHAUST FUMES EMITTED BY A DIESEL ENGINE
(FR) PROCÉDÉ DE NETTOYAGE D'EFFLUENTS LIQUIDES D'UN LAVEUR PAR VOIE HUMIDE TRAITANT LES FUMÉES D'ÉCHAPPEMENT ÉMISES PAR UN MOTEUR DIESEL
Abstract:
(EN) For simple, compact and economical cleaning of liquid effluents (4) from a wet scrubber (WS) treating exhaust fumes (1) emitted by a diesel engine (E), the invention provides that: - solid particles (7), containing between 25 and 75 % by weight of activated carbon and between 25 and 60 % by weight of cement and having a mean size of between 30 μm and 500 μm, are placed in the scrubber (WS), and - the effluents to be cleaned (4), on leaving the scrubber (WS), are sent to a solid-liquid separator (SLS) where the effluents are separated into a clear fraction (5) and a sludge (6) containing the solid particles (7).
(FR) Pour le nettoyage simple, compact et économique d'effluents liquides (4) d'un laveur par voie humide (WS) traitant les fumées d'échappement (1) émises par un moteur diesel (E), l'invention prévoit que : des particules solides (7), contenant entre 25 et 75 % en poids de charbon actif et entre 25 et 60 % en poids de ciment et ayant une taille moyenne comprise entre 30 µm et 500 µm, sont placés dans le laveur (WS), et les effluents à nettoyer (4), en sortant du laveur (WS), sont envoyés à un séparateur solide-liquide (SLS) où les effluents étant séparés en une fraction claire (5) et une boue (6) contenant les particules solides (7).
