An aerator comprises at least two flowing chambers, equipped by pressure, outlet and air tubes, besides pressure tubes are joined with a pressure pipe-line, and perforated nozzles are placed in outlet tubes. For the possibility of providing of additional water mass intake and turbulence transition of stream at the inlet of distribution junction and as a consequence making of perforated nozzles of a permanent flow in initial section, and also setting pressure inside of these nozzles, sufficient for the uniform outflow of liquid-gas mixture throughout the length, the outlet tubes of flowing chambers are joined with perforated nozzles by bushings, having perforation, diameter of holes of which coincides with diameter of perforation holes of nozzles, besides perforation hole axes of bushings placed in mutually perpendicular planes at a distance from bushing end, equal to (0.5-0.6) bushing length, and perforated nozzles are equipped in outlet end with bends, free end of which is directed to the perforation side. |
