The invention relates to the devices intended for atomization of liquids with the purpose of obtaining fine aerosol. The proposed device is intended for aerosolization of labile liquids, it includes 1 or several ejector atomizers arranged with possibility of their rotation with respect to a horizontal plane. The atomizer contains the chamber with the nozzle, in which the branch pipes for supplying of liquid material to be atomized and air are introduced, at that the air supply branch pipes are tangentially arranged in the chamber, and the sizes of the branch pipes openings and of the nozzle are related by the equation Do=(0,÷0,7)D 2 c/Dk, wherein Do is the diameter of liquid supply branch pipe, Dc is the diameter of the outlet nozzle, Dk is the diameter of the air inlet channel, and the atomizers themselves are arranged in the cylindrical container above the liquid surface in such a way that the jet coming out therefrom is chordwisely oriented with respect to the walls of the cylindrical container, at that the projection of the central axis of the aerosol spray on the cylinder walls doesnt cross the top edge of the walls during at least one turn at motion of the aerosol particles. The results of the conducted tests showed, that the declared device allows to obtain stable fine aerosol of liquids with properties varying in the wide range.
