METHOD OF HYDRODYNAMIC ACTIVATION OF THE RAW MATERIALS (VARIANTS) AND INSTALLATION FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: chemical and petrochemical industries; pulp and paper industry; foodprocessing and other industries. SUBSTANCE: the invention presents a method of hydrodynamic activation of the raw material (variants) and an installation for its realizations (variants), that maybe used in chemical, petrochemical, pulp and paper, food-processing and other industries. The technical result consists in expansion of their technological capabilities at the expense of the opportunity of application in many industries and to increase a degree of activation of the raw materials processing and synthesis of new products. The method provides for a dispersion of a mixture of a feed stock with a gas or with a liquid and a gas in a dispersion installation the supplied with Laval's nozzle, in which the gas is fed, admix the gas coming out of Laval's nozzle with a torrent of a feed stock or with a mixture of the feed stock with a liquid, speed up the traffic of the torrent of the produced mixture up to a supersonic speed and realize an impact type and supersonic effect on it. Then the dispersed mixture is directed for the cavitational treatment. The installation contains: Laval's nozzle; a cavitation reactor; a dispersion device, that has a cyclone separator; a chamber for hypersonic treatment and a mixing chamber, in which the exit end of laval nozzle is installed; the second cyclone separator for delivery of the dispersed mixture; an additional Laval's nozzle placed coaxially to the second cyclone separator; a contraction and a hydrodynamic pipe, the inlet end of which is connected to the contraction, and its outlet end is connected to the cavitation reactor. EFFECT: expansion of technological capabilities, opportunity for application in many industries, increased degree of activation of the raw materials processing, synthesis of new products. 6 cl, 1 dwg, 4 ex _
