FIELD: process engineering.SUBSTANCE: invention relates to generation of gas-drop jets and may be used in fire-fighting and agriculture for irrigation. Proposed device comprises fluid and gas feed systems and nozzle. Fluid is fed in two ways: axially via feed pipe and confuser and cylindrical nozzle aligned with said pipe, and tangentially via case composed of cylinder-conical sleeve aligned with cylindrical case. Vortex annular chamber with fluid feed branch pipe is secured on cartridge cylindrical part. Two lines of fluid feed tangential channels are made along edges of said annular chamber. At least three tangential channels are arranged in every said line to communicate annular chamber with housing cylindrical chamber. Shaped nozzle is secured to said chamber and aligned therewith and consisting of two concatenated confusers. First confuser connected with housing cylindrical chamber has conical shell with cone vertex angle smaller than that of second confuser connected with outlet nozzle. Nozzle outlet cross-section is shaped to rectangle.EFFECT: increased atomisation.2 dwg |
