Abstract

The invention discloses a continuous aftertreatment system and method for preparing nano materials through supercritical water thermal synthesis. Through buffering cleaning tanks arranged in parallel,simultaneous cleaning of separated products in different batches and continuous running of a continuous flow centrifugal separator can be achieved, the production efficiency is effectively improved,and the number of facilities is reduced. Through the arrangement of a recycling system of a wrapping agent and a solvent of the wrapping agent, complete recycling of the wrapping agent and the wrapping agent solvent can be achieved, and the running economical efficiency of the system is obviously improved. Through the arrangement of a three-phase separator and a gas pressure changing adsorption device, gas-phase products in reaction products can be separated out, valuable gas in the gas-phase products is adsorbed and collected, and high economic benefits are brought.
