The invention relates to a small-diameter carbon nanotube purification system for heat recovery. The small-diameter carbon nanotube purification system comprises a fluid reaction bed, an acid storage tank, a grinder, two heat exchangers and two filter presses, acid steam discharged out from the fluid reaction bed is fed into one heat exchanger, acid cooling fluid discharged by the heat exchanger is fed into the acid storage tank, small-diameter carbon nanotube crude solution discharged out from the fluid reaction bed is fed into another heat exchanger, the small-diameter carbon nanotube crude solution cooled by the heat exchanger is fed into one filter press, the acid solution discharged out form the filter press is fed into the acid storage tank, small-diameter carbon nanotube crude press cake discharged from the press filter is fed into the grinder, and the small-diameter carbon nanotube crude cake ground by the grinder is fed into the next filter press to obtain finished small-diameter carbon nanotubes. Heat energy in the fluid reaction bed is fully utilized, heat energy in acid steam reacted and released is absorbed by the jacketed heat exchanger, and heat energy in the small-diameter carbon nanotube crude solution is absorbed by the plate heat exchanger.
Description
technical field [0001] The invention relates to a small-diameter carbon nanotube purification system for heat energy recovery, and belongs to the technical field of carbon nanotube production. Background technique [0002] Carbon nanotubes are tubular nanomaterials composed of carbon atoms. Tube walls containing multiple layers of carbon atoms are called multi-walled carbon nanotubes (MWNT), and those containing a single layer of carbon atoms are called single-walled carbon nanotubes (SWNT). Since the discovery of carbon nanotubes, researchers have been paying attention to their unique structure and excellent properties. It has potential application prospects in new conductive / high-strength conforming materials, electronic devices, catalyst support materials, etc. [0003] The preparation processes of carbon nanotubes mainly include arc discharge method, laser etching method, chemical vapor deposition method, solid-phase pyrolysis method, flame synthesis method, glow disch...
