Problems solved by technology

However, there are still obvious shortcomings in this method, that is, the secondary swirling flow reactor needs to be used in series with a multistage centrifugal pump and a shell and tube heat exchanger, when the inlet pressure of the secondary swirling flow reactor It reaches 2.0 MPa, the inlet flow is 200 ml / s, and the total mechanical energy of the fluid is about 0.4 kW

Abstract

The invention relates to the field of chemical engineering and technology. Aiming at solving the problems of high energy consumption and low efficiency of an existing stripping technology of the two-dimension nano materials, the invention provides a method for efficient supergravity stripping of two-dimension nano materials. The method comprises the following steps: firstly, feeding a two-dimensional stratified material into dispersion liquid for fully wetting and uniformly mixing to obtain material dispersion liquid, and then inputting the material dispersion liquid to a circular storage tank; secondly, outputting the material dispersion liquid from an outlet in the lower end of the circular storage tank, enabling the material dispersion liquid to enter a central entrance of a secondary rotary flow reactor rotating at high speed through a pipeline; enabling feed liquid flowing out of the reactor outlet to enter an entrance of a shell and tube heat exchanger through the pipeline; and refluxing the feed liquid flowing out of the shell and tube heat exchanger into the circular storage tank, and cycling for multiple times according to the steps, thus obtaining a few-layer two-dimension nano material with less than 3 layers. The method disclosed by the invention can realize quick, efficient, low-cost, large-scale and high-quality production of various two-dimension layered nano materials.

Description

technical field [0001] The invention relates to the fields of chemical engineering and technology, in particular to a method for stripping two-dimensional nanomaterials with high-efficiency supergravity. Background technique [0002] High-gravity technology is a new technology to strengthen multiphase flow transfer and reaction process. Due to its wide applicability and its small size, light weight, low energy consumption, easy operation, easy maintenance, safety, reliability and The advantages of flexibility and better adaptability to the environment make supergravity technology have broad commercial application prospects in environmental protection, materials, biology, chemical and other industrial fields. The basic principle of high-gravity engineering technology is to use the unique flow behavior of multi-phase flow system under the condition of high-gravity field to strengthen the relative velocity and mutual contact between phases, so as to realize the efficient moment...
