Abstract
A system for preparing nanoparticles by supercritical hydrothermal synthesis is provided. Firstly, a mixture of a first reactant and a second reactant and high-temperature water at an outlet of a heating furnace (10) are mixed and are heated to a reaction temperature, the mixture is connected to a supercritical hydrothermal synthesis reactor (14), and a product at an outlet of the supercritical hydrothermal synthesis reactor enters a heat regenerator (9); hot water at an outlet of a low-temperature section of the heating furnace (10) first enters the heat regenerator, and then enters a high-temperature section of the heating furnace so as to be continuously heated to a set temperature; fluid at the pipe side outlet of the heat regenerator separately passes through a heat exchange coil in a first reactant modulation pool (1) and a steam generator (2) in a waste heat power generation system (20).
