Abstract

L'injecteur selon l'invention se distingue en ce qu'il comprend au moins un élément déflecteur disposé dans cette chambre de mélange sur l'axe de l'entrée du liquide, pour répartir ce liquide dans toute la section transversale de la chambre de mélange; ce déflecteur peut être plat, conique ou parabolique, ou en forme de languette décalée axialement par rapport à la chambre de mélange. Un tel injecteur convient en particulier pour le traitement d'effluents liquides ou pour les opérations de fermentation.
