MATERIAL TREATMENT METHOD APPARATUS Russian patent published in 1995 - IPC

FIELD: treatment of fluid material. SUBSTANCE: method involves subjecting crystallizable fluid medium to pressure pulses in chamber; reducing pressure to excite flowing of gas solutions in intermolecular or interatomic spaces in fluid medium and formation of gas bubbles; solving bubbles in fluid medium by flows of gas solution due to increase of pressure in chamber. Apparatus has hermetically sealed chamber with rigid enclosure, convex bottom and cover, fluid medium inlet-outlet system in the form of pipeline with return valves positioned in the direction of flow, regulating units, flow regulators at inlet and discharge ends and treatment devices for creating wave oscillations of fluid medium. Invention is based on physical force of mechanical pressure oscillations exciting flowing of gas solution in fluid medium. This physical force change structure and parameters of molecule flux - extension and contraction of bonds, deformation of valence and torsion corners, Van-der Walls forces, specific surface of molecule S/V=10⁹ m^-1 and mass-heat exchange factor presented as ratio of fluid medium speed in pseudo-crystal to relative speed of molecules at the same instant and in the same volume, with value of ratio to extreme value of 10¹¹. It allows reacting materials to be conveyed in countercurrent in excited state and separation and cleaning of fluid medium from any suspended contaminant to be provided. EFFECT: increased efficiency and high quality of treated materials. 13 cl
