Abstract

Vynález z oblasti nanotechnologií se týká nového způsobu přípravy nanočástic desintegrací pevných mikročástic kavitujícím kapalinovým paprskem v kapalinové disperzi, založeném na extrémním mechanickém namáhání při implozi ryze parních kavitačních mikrobublin na jejich povrchu. Zařízení je tvořeno desintegrační komorou (1) prvního stupně A.sub.1.n., kde desintegrační komora (1) prvního stupně A.sub.1.n.je tvořena systémem propojených trubic. Na desintegrační komoru (1) prvního stupně A.sub.1.n.je ze strany napojena vstupní kavitační trubice (2), která je zakončena zúžením v podobu trysky (3). Z boku desintegrační komory (1) prvního stupně A.sub.1.n.jsou napojeny vtoková trubice (6.1) a výtoková trubice (6.2) a ze strany protilehlé ke vstupní kavitační trubici (2) je napojena zužující se výstupní kavitační trubice (5). Dovnitř odplyněné kapalinové disperse pevných mikročástic a nanočástic proudící vtokovou trubicí (6.1) pod statickým, nebo modulovaným tlakem vyšším než 0,1 MPa vtéká kavitační trubicí (5) vysokoenergetický kapalinový paprsek odplyněné kapalné disperze, který v okolí svého vstupu do vnitřního prostoru desintegrační komory (7) vyššího stupně A.sub.1+n.n.vytváří zónu intenzivní kavitace. Zařízení může být provedeno také jako vícestupňové tak, že se sériově zapojí více desintegračních komor, přičemž vtoková trubice (6.1) a výtoková trubice (6.2) mohou být vzájemně propojeny a prostřednictvím čerpadla může kapalinová disperze zařízením cirkulovat. Způsob a zařízení podle vynálezu může být použito při procesech, u kterých je žádoucí snížení kontaminace dezintegrovaného materiálu materiály mlecích těles a vnitřků zařízení.The invention in the field of nanotechnologies relates to a new process for the preparation of nanoparticles by disintegrating solid microparticles with a cavitating liquid jet in a liquid dispersion based on extreme mechanical stress when implying pure steam cavitation microbubbles on their surface. The device comprises a first stage disintegration chamber (1) of the first stage, where the first stage disintegration chamber (1) is formed by a system of interconnected tubes. The inlet cavitation tube (2) is connected to the first stage disintegration chamber (1) of the first stage by a constriction in the form of a nozzle (3). An inlet tube (6.1) is connected from the first stage of the first stage A.sub.1. Of the disintegration chamber (1) and a tapered outlet cavitation tube (5) is connected from the side opposite the inlet cavitation tube (2). ). A high-energy liquid jet of degassed liquid dispersion flows through the degassed liquid dispersion of solid microparticles and nanoparticles flowing through the intake tube (6.1) under static or modulated pressure higher than 0.1 MPa, which in the vicinity of its entry into the interior of the disintegration chamber ( 7) higher degree A.sub.1 + does not create an intensive cavitation zone. The apparatus may also be designed as a multistage device by connecting multiple disintegration chambers in series, wherein the inlet tube (6.1) and the outlet tube (6.2) may be interconnected and the pump may circulate the liquid dispersion through the device. The method and apparatus of the invention may be used in processes in which it is desired to reduce contamination of the disintegrated material by the materials of the grinding bodies and the interior of the apparatus.
