Production device for preparing graphene by virtue of ultrasonic assistance

Abstract

The invention relates to a graphene preparation technique, and aims to provide a production device for preparing graphene by virtue of ultrasonic assistance. The reactor of the production device is a tubular reactor, and a plurality of the tubular reactors having the same structure are sequentially and serially connected or are mutually connected in parallel through pipelines; the tubular reactors comprise tubular reactor main bodies; two ends of the reactor main bodies are sealed; each tubular reactor is equipped with an ultrasonic generation device; the tool head of each ultrasonic generation device is connected with one end part of the corresponding reactor main body; cooling jackets are arranged around the outer sides of the reactor main bodies. The production device provided by the invention can be added into a conventional production line for preparing graphene, raw materials are not contaminated, the capacity of a conventional production line can be increased, and the purposes of increasing the preparation amount of graphene and lowering the preparation cost can be achieved; the production device is convenient to debug and overhaul; single complete equipment is not mutually interfered after being powered on, industrial continuous production can be achieved, and later production line capacity increase can be facilitated.

Description

technical field [0001] The invention relates to graphene preparation technology, in particular to an industrialized production device for preparing graphene using ultrasonic assistance. Background technique [0002] Graphene has extraordinary physical properties, such as high specific surface area, high electrical conductivity, high mechanical strength, easy modification and mass production. The successful exfoliation of graphene in 2004 made graphene a new potential material for the "post-silicon era" of nano-scale transistors and circuits, and its product development and applications are currently increasing dramatically around the world. However, due to the problems of yield, preparation cost and finished product quality, it has not been widely used. [0003] At present, the main preparation methods of graphene are chemical methods and physical methods. [0004] The physical method usually uses cheap graphite or expanded graphite as raw material, and prepares single-lay...

AI Technical Summary

Problems solved by technology

However, the former has relatively high requirements on the reactor, and needs to be added to the stirring system, and the production efficiency is also low; the ultrasonic energy of the latter is relatively small, so it can only be applied to a small number of preparation methods

Neither is suitable for industrialized continuous production, let alone the possibility of expansion
