Device for spraying a treatment fluid and system for spraying a treatment fluid including at least one such device

摘要

The device (100) has conveying units formed of openings (103), compartmentalizing member (130) and nozzles (170) for conveying central air streams (F120, F140) to a rotative member (140). The compartmentalizing member has exhaust orifices (137) for circulating the streams from a chamber (106) to an exhaust chamber (107). The orifices are distributed on sides (Yg, Yd) of the compartmentalizing member diametrically opposite on side of a central axis (X1). Spraying direction (Dp) of sprayed liquid stream (Fp) defines an ogive profile based on the rotative member and flattened on the sides.
