Abstract

The invention relates to the technical field of chemical reaction engineering, and especially relates to a method and an apparatus for rapid hydrothermal synthesis. The apparatus comprises a power mechanism, a plurality of liquid storage devices and a reactor, the liquid storage devices are connected with the reactor through a channel transition mechanism, and the channel transition mechanism is provided with a flow rate control device; and the reactor includes a channel distribution structure and a multiple heat exchange assembly, the multiple heat exchange component uses a high temperature and high pressure hot liquid as a heat source, the multiple heat exchange assembly is composed of a plurality of pinch plates which can be vertically buckled up and down, grooves are arranged at two sides of the middle pinch plate, the grooves of the adjacent pinch plate are buckled to form a plurality of closed channels, and the channel distribution structure is communicated with the closed channels of the multiple heat exchange assembly. The apparatus has a strong heat exchange function, and can prepare nano-composite particles with various crystal phases and a complicated structure under hydrothermal conditions, and the obtained nano-composite particles can be directly used without hydrothermal aging treatment, so the process flow is obviously shortened, and the process cost of the product is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical reaction engineering, in particular to a rapid hydrothermal synthesis device and method. Background technique [0002] Nanocomposite particles are a composite multiphase structure formed by covering several layers of uniform nanometer films or particles on the surface of a material with a size ranging from micrometers to nanometers. The matrix and cladding materials are combined with each other through physical or chemical interactions to form a composite structure, and the composite performance can be adjusted by controlling the composition and structure of the two. By tailoring the structure and size, their magnetic, optical, mechanical, thermal, electrical, catalytic, adsorption and other properties can be adjusted, so they have properties different from single-component nanomaterials. In materials science (such as: solid electrolyte, Semiconductors, ceramics, photosensitive materials), chemi...
