ATOMIZER Russian patent published in 1997 - IPC

FIELD: atomizing liquids, heavy hydrocarbons in particular; petrochemical, power and other industries. SUBSTANCE: fuel is fed to tube 4. In area of impeller 6, flow velocity increases, pressure drops to value of vapor saturation pressure and liquid boils forming microbubbles. After blades of impeller 6, microbubbles collapse forming microstructures. Part of flow of atomizer entering housing 1 is fed to end-piece 5. Main flow of atomizer is fed to area after impeller 6 through swirler 8. Rotation of impeller 6 makes it possible to attain cavitation mode of flow at lower velocities of fuel flow. Position of tail section of tube 4 is changed by moving this tube. Tail section of tube 4 is made in form of adjusting needle 12 secured by means of radial plates 13 having sharp edge which enhances conditions of contact of cavity with flow of atomizer after swirler 8. Position of plates 13 and their profile provide for swirling of fuel flow towards side opposite to that of swirling the flow by impeller 6 which is moved along tube 4 together with end-piece 5, thus enhancing interaction of flows of fuel and atomizer. EFFECT: intensification of fuel dispersion process. 1 dwg
