FIELD: mining.
SUBSTANCE: hydro-transporting pressurised system with elements of cavitation consists of pipe with bends and of connected between them narrowing and expansion elements. The system is equipped with complex of jet aero-hydrodynamic cavitation and with a rigidly fixed vortex. The narrowing element and expansion element are connected non-rigidly and pressure tight. The system of jet aero-hydrodynamic cavitation consists of an upper and lower nozzles directed so as to provide air supply along the motion of the main direction of hydro-flow in the zone of the expansion element. Also the system of jet aero-hydrodynamic cavitation is installed between the narrowing and expansion elements. The interior diameter of the end of the expansion element coupled with the narrowing element through seal rings is bigger, than the interior diameter of the narrowing element end. The crevice of the upper nozzle is installed so as to direct air supply to the wall of the expansion element, while the crevice of the lower nozzle is installed to direct air supply to the central part of the main direction of hydro-flow motion. Vortexes are arranged inside the narrowing and expansion elements and are made in form of right triangles.
EFFECT: intensification of process of sand-clay rock destruction by means of aero-hydrodynamic cavitation with pressurised hydro-transporting to systems of deep processing.
