VORTEX EJECTOR Russian patent published in 2013 - IPC F04F5/42 

FIELD: machine building.

SUBSTANCE: vortex ejector is designed for injection of a gas flow. Ejector includes cylindrical housing, tangential working gas flow inlet branch pipes, tangential mixed flow outlet branch pipe, injected flow inlet branch pipes located coaxially to cylindrical housing of the device; diameter of injected gas flow inlet branch pipe is 0.25÷0.8 of diameter of cylindrical housing of the device; distance from lower edge of tangential working gas flow inlet branch pipes to upper edge of tangential mixed flow outlet branch pipe is 0÷0.5 of diameter of cylindrical housing of the device; width of cross section of tangential mixed flow outlet branch pipe is 0.4÷0.5 of diameter of cylindrical housing of the device; cross section area of tangential mixed flow outlet branch pipe is 0.25÷1.6 of total cross section area of tangential working flow inlet branch pipes and injected flow inlet branch pipe.

EFFECT: proposed ratios of the main structural parameters of the device are optimum and allow obtaining rational operating parameters of vortex ejector.
