Abstract

La présente invention concerne une buse (1) pour un système de pulvérisation (60). La buse (1) comprend un premier passage fluidique (11) permettant une circulation de gaz, un deuxième passage fluidique (21) permettant une circulation de liquide et une zone de jonction (31) entre le premier passage fluidique (11) et le second passage fluidique (21) dans laquelle le deuxième passage fluidique (21) débouche par une ouverture (22). Ladite ouverture (22) a de préférence la forme d'une fente. La buse (1) comprend de préférence une partie convergente-divergente (41, 42, 43) formant une tuyère de Laval, en amont ou en aval de la partie convergente-divergente . En outre, l'invention concerne un système de pulvérisation (60) dans lequel un circuit de liquide (80, 62, 21) est mis sous pression par du gaz circulant dans un circuit de gaz (70, 61, 11).The present invention relates to a nozzle (1) for a spray system (60). The nozzle (1) comprises a first fluidic passage (11) allowing gas to circulate, a second fluidic passage (21) allowing liquid to circulate and a junction zone (31) between the first fluidic passage (11) and the second fluidic passage (21) in which the second fluidic passage (21) emerges through an opening (22). Said opening (22) preferably has the shape of a slot. The nozzle (1) preferably comprises a convergent-divergent part (41, 42, 43) forming a Laval nozzle, upstream or downstream of the convergent-divergent part. Furthermore, the invention relates to a spray system (60) in which a liquid circuit (80, 62, 21) is pressurized by gas circulating in a gas circuit (70, 61, 11).
