FIELD: heating. ^ SUBSTANCE: invention is related to equipment for air conditioning and may be used for creation of comfortable microclimate conditions in industrial rooms, in particular, as systems for local additional humidification of air. In system of air humidification, which consists of pneumatic nozzles, networks of pipelines that serve for water supply to them as well as compressed air, and unit of pneumatic nozzle control, pneumatic nozzle is made as acoustic, which contains casing with internal generator of acoustic oscillations in the form of nozzle and resonator, tubes for supply of air and liquid, at that casing is arranged in the form of vertically installed cylindrical bushing, in top part of which tube is installed for air supply, and tube for liquid supply is installed perpendicular to its axis, at that inside casing, coaxially to it, bushing is rigidly fixed with top and bottom flanges, at that bottom flange is rigidly fixed in bore arranged in casing, and inside bushing, coaxially to it, annular volume resonator is installed, which is arranged in the form of a cup with conical surface, cup is pressed on rod with diameter d of resonator, and in its tail part fixing discs are installed, which are arranged in the form of elastic tabs that interact with internal surface of bushing, and in bottom flange at least one nozzle is installed at the angle to resonator axis, value of which lies in the following interval of values: 20°/40°, at that extension of nozzle axis lies on circumference that is located in the middle part of resonator conical surface. ^ EFFECT: higher efficiency and reliability of water pneumatic spraying process. ^ 3 cl, 2 dwg |
