Title (EN) DEVICE FOR ATOMIZING A FLUID
(FR) DISPOSITIF D'ATOMISATION D'UN FLUIDE
Abstract:
(EN) The invention relates to a device (10) for atomizing a fluid, a use of such device (10) and a method for atomizing a fluid. The device (10) for atomizing a fluid comprises a pressure inlet (13) for providing a pressurized gas (23), a first fluid inlet (11) for providing a first fluid (21), a second fluid inlet (12) for providing a second fluid (22), a chamber (14), a first outlet (15), and a second outlet (16). The pressure inlet (13), the first fluid inlet (11) and the second fluid inlet (12) lead into the chamber (14) and the first outlet (15) and the second outlet (16) leave the chamber (14). The first and second fluids might be each a gas or a liquid. The first and second fluids might be different or the same. The pressure inlet (13), the first fluid inlet (11) and the second fluid inlet (12) are configured such that the pressurized gas (23) provided by the pressure inlet (13) draws the first fluid (21) and the second fluid (22) into the chamber (14). The chamber (14) is part of a fluidic oscillator configured to alternating attach the pressurized gas (23) to the first fluid inlet (11) or to the second fluid inlet (12), so that the pressurized gas (23) alternating draws the first fluid (21) and the second fluid (22) into the chamber (14), atomizes the first fluid (21) and the second fluid (22) and outputs the atomized first fluid (21) and the atomized second fluid (22) alternating through the first outlet (15) and the second outlet (16).
(FR) L'invention concerne un dispositif (10) pour l'atomisation d'un fluide, une utilisation d'un tel dispositif (10) et un procédé d'atomisation d'un fluide. Le dispositif (10) pour l'atomisation d'un fluide comprend une admission de pression (13) permettant de fournir un gaz sous pression (23), une première admission de fluide (11) permettant de fournir un premier fluide (21), une seconde admission de fluide (12) permettant de fournir un second fluide (22), une chambre (14), une première évacuation (15) et une seconde évacuation (16). L'admission de pression (13), la première admission de fluide (11) et la seconde admission de fluide (12) débouchent dans la chambre (14) et la première évacuation (15) et la seconde évacuation (16) quittent la chambre (14). Les premier et second fluides peuvent être chacun un gaz ou un liquide. Les premier et second fluides peuvent être différents ou identiques. L'admission de pression (13), la première admission de fluide (11) et la seconde admission de fluide (12) sont configurées de sorte que le gaz sous pression (23) fourni par l'admission de pression (13) aspire le premier fluide (21) et le second fluide (22) dans la chambre (14). La chambre (14) fait partie d'un oscillateur fluidique configuré pour fixer en alternance le gaz sous pression (23) à la première admission de fluide (11) ou à la seconde admission de fluide (12), de sorte que le gaz sous pression (23) attire en alternance le premier fluide (21) et le second fluide (22) dans la chambre (14), atomise le premier fluide (21) et le second fluide (22) et émette le premier fluide atomisé (21) et le second fluide atomisé (22) en alternance à travers la première évacuation (15) et la seconde évacuation (16).
