Abstract

L'invention porte sur une buse (10) servant à mélanger un gaz tel que de l'air et un liquide tel que de l'eau et à éjecter un brouillard atomisé de gouttelettes liquides. Ladite buse comprend un corps comportant un premier (60), un deuxième (44) et un troisième (52) passages annulaires longitudinaux. Le gaz sous pression est introduit dans le premier passage (60) qu'un premier orifice annulaire (68) restreint relie au troisième passage (52). Le liquide est introduit dans le deuxième passage (44) qu'un deuxième orifice annulaire (48) restreint relie au troisième passage (52). Le liquide et le gaz sont intimement mélangés dans le troisième passage (52). Un troisième orifice annulaire (72) restreint relie le troisième passage (52) à l'extérieur, ce qui entraîne l'éjection violente du mélange gaz liquide par la buse via le troisième orifice annulaire restreint, le liquide étant atomisé en fines gouttelettes contrôlées dans le gaz éjecté.
