FIELD: chemical; petrochemical; pulp and paper; food processing and other industries. SUBSTANCE: the invention presents a method of hydrodynamic activation of the raw materials (versions) and an installation for its realizations (versions) and is dealt with activations of the raw materials by hydrodynamic action. The method and installation may be used in chemical, petrochemical, pulp and paper, food processing and other industries. The technical result is an expansion of technological capabilities at the expense of their application in any industries, an increase of a degree of activation of the raw materials and synthesis of new products. A method provides for a dispersion of a mixture of a feed stock with a gas or with a gas and a liquid in a dispersion device supplied with the Laval's nozzle, in which the gas is fed. Then the gas coming out of the Laval's nozzle is mixed with a flow of the feed stock or with the mixture of the feed stock with a liquid, speed up the movement of the flow of the produced mixture up to a supersonic speed and an impact and ultrasonic action on it is exercised. Then the dispersed mixture is directed to the cavitation treatment. The installation has a Laval's nozzle, a cavitation reactor, a dispersion device having a cyclone separator, a chamber of supersonic treatment and a mixing chamber, in which the outlet end of the Laval's nozzle is installed, the second cyclone separator for feeding the dispersed mixture, an additional Laval's nozzle placed coaxially to the second cyclone separator, the contraction and a hydrodynamic pipe, the inlet end of which is connected with the contraction and its outlet end - with the cavitation reactor. EFFECT: the method allows to expand the technological capabilities of the process and to increase the degree of activation of the raw materials and synthesis of new products. 6 cl, 1 dwg, 4 ex
