Abstract: A mechanical device used to atomize liquids. The device eliminates circular instability at elevated generation frequencies, producing drops of 30-40?. This is achieved when the central bar has been made with the diameter equal to the diameter of the nozzle. The longitudinal grooves in the central bar are located at the distance which does not exceed the quarter of the wave length of the nozzle working frequency. The depth of grooves at the central bar 8, their width t, number n, the generation frequency f, the width of the resonance groove of the pneumoacoustic bar nozzle a and the distance between the circular gas nozzle H and the bottom of the ring-like resonator were selected based on the ratio: S=n·8·t, where S is the aggregate cross section of grooves upon the preset gas efficiency; 12.5˜f·8˜15; 1.8˜a/8˜2.1; 7˜H/8˜8.

Abstract: The invention refers to devices which utilize periodic blast waves for dispersion of liquids, when these waves are created in the supersonic gas jet upon its slowing down by the hollow resonator. The technical outcome of the invention is the increased dispersity of the produced drops. The technical result is achieved by the installation of the resonator inside the body of the pneumoacoustic atomizer of liquids, which create (at the distance l from the deflector) the groove which width is ? and the depth is h. The internal part of the resonator is shaped as the conical funnel of the outlet diameter dk. Diffusion element has been attached to the conical funnel. The inlet channel for liquids was made as the nipple. The diameter of the critical cross section has been selected based on the condition providing that one of the lateral resonances must be obtained at the operational frequency of the gas jet generator.

Abstract: The invention refers to mechanical devices used to atomize the liquids, create fog in the rooms, and humidify air in the weaving sheds, glass houses; and also for decontamination of medical rooms through the use of the bactericide solutions. The technical result of the invention is the elimination of the circular instability upon the elevated generation frequencies, production of drops of 30-40 um. The technical result is achieved when the central bar (within the pneumoacoustic bar nozzle) has been made with the diameter equal to the diameter of the nozzle. The longitudinal grooves in the central bar are located at the distance which does not exceed the quarter of the wave length of the nozzle working frequency.
