METHOD OF RESONANCE EXCITATION OF LIQUID AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2004 - IPC

FIELD: power engineering; petrochemical and oil refining industries. SUBSTANCE: proposed method includes delivery of liquid to impeller 2 whose rated rotational speed n is set depending on selected number K of its outlet holes 8 over its peripheral circular surface into circular resonance cavity 5 according to empirical ratio n = 3,84K^-1,5×10⁶ (r/min) ±5%; resonance excitation of liquid is performed at empirical ratio R=(1.281 ... 1.560)K, mm, where R is radius of peripheral circular surface of impeller. Device proposed for realization of this method has impeller 2 with peripheral circular wall 18 and several outlet holes 8, stator 4 with wall 19 coaxial relative to impeller and outlet hole 11, circular resonance cavity 5 formed by peripheral circular wall of impeller and coaxial wall of stator which is communicated with storage chamber 10. Magnitude of external radius of peripheral circular wall of impeller is equal to R=(1.281 ... 1.560)K, mm and radial extent of outlet holes of impeller is equal to L=(0.16 ... 0/42)K, mm, where K is number of outlet holes of impeller. EFFECT: improved quality of liquid being treated. 5 cl, 2 dwg, 4 tbl
