Title (EN) DEVICE FOR GENERATING DROPLETS FROM A LIQUID COMPRISING IMPROVED MEANS FOR DIFFUSION OF THE MIST, AND METHOD FOR IMPLEMENTING SAME
(FR) DISPOSITIF DE GENERATION DE GOUTTELETTES A PARTIR D'UN LIQUIDE COMPRENANT DES MOYENS AMELIORES DE DIFFUSION DU BROUILLARD, ET SON PROCEDE DE MISE EN ŒUVRE
Abstract:
(EN) This device comprises a hollow body delimiting a generating space, means for generating droplets from a liquid jet (J) flowing inside said chamber, means for discharging a majority of the liquid jet, as well as means for diffusing droplets of a mist, formed from said jet. According to the invention, the generating space comprises an upstream chamber (5) referred to as a common chamber, intended for the flow of both the liquid and the droplets of mist, this chamber extending axially with reference to the space, the diffusion means comprise at least one diffusion branch (6, 7) extending obliquely from the chamber, both radially towards the outside of this chamber and axially away from the nozzle, in plan view from above, and the discharge means (8) extend said common chamber downstream, beyond the junction between the diffusion branch and the common chamber. The invention makes the device of the invention very compact, since the dimensioning of the device takes account of the fact that the fine drops are generated over a small axial distance at the outlet of the nozzle. Furthermore, the device according to the invention can advantageously be put into operation, even in the absence of ventilation means.
(FR) Ce dispositif comporte un corps creux délimitant une enceinte de génération, des moyens de génération de gouttelettes à partir d'un jet de liquide (J) s'écoulant à l'intérieur de ladite enceinte, des moyens d'évacuation d'une majeure partie du jet de liquide, ainsi que des moyens de diffusion de gouttelettes d'un brouillard, formé à partir dudit jet. Selon l'invention, l'enceinte de génération comprend une chambre amont (5) dite chambre commune, destinée à l'écoulement à la fois du liquide et des gouttelettes de brouillard, cette chambre s'étendant axialement en référence à l'enceinte,les moyens de diffusion comprennent au moins une branche de diffusion (6, 7) s'étendant de manière oblique à partir de la chambre, à la fois radialement vers l'extérieur de cette chambre et axialement à l'opposé de la buse, en vue de dessus, et les moyens d'évacuation (8) prolongent ladite chambre commune vers l'aval, au-delà de la jonction entre la branche de diffusion et la chambre commune. L'invention confère une grande compacité au dispositif de l'invention, puisque le dimensionnement de ce dernier tient compte du fait que les fines gouttes sont générées sur une faible distance axiale en sortie de la buse. Par ailleurs, le dispositif conforme à l'invention peut avantageusement être mis en service, même en l'absence de moyens de ventilation.
