Abstract

Un épurateur des gaz d'échappement comprend une série de passages à contre-courant emboîtés, y compris un plénum chaud ayant une coupe en étoile. Les gaz d'échappement provenant du plénum chaud passent par un bain liquide et s'écoulent dans une direction opposée à travers un réseau incliné d'ailettes de mélangeage espacées, plates et chevauchantes, ce qui produit une turbulence dans les gaz d'échappement et permet la formation des microbulles finement dispersées, qui améliorent la dilution des polluants gazeux dans le liquide d'épuration. Des ailettes antibuée séparent les liquides entraînés des gaz d'échappement. Le plénum chaud réchauffe les gaz d'échappement et les porte à un niveau insaturé. L'épurateur est hautement efficace pour réduire les matières particulaires, épurer les gaz d'échappement du dioxyde de soufre et du dioxyde d'azote, et réduire leur signature thermique ainsi que leur manifestation visuelle.
