The carbon nanotube purification system for precipitating metal ions includes a fluid reaction bed, a jacketed heat exchanger, an acid storage tank, a stirring tank, a metal ion precipitation tank, and two filter presses. The acidic steam discharged from the fluid reaction bed is passed through into the jacketed heat exchanger, the acidic cooling liquid discharged from the jacketed heat exchanger is passed into the acid storage tank, and the crude carbon nanotube solution discharged from the fluid reaction bed is filtered by a filter press to discharge the acidic cooling liquid. The solution is passed into the acid storage tank, the crude carbon nanotube solution discharged from the filter press is passed into the stirred tank, and then passed into the next filter press to obtain the finished carbon nanotube, the solution discharged from the stirred tank is passed into the metal Ion precipitation tank, the acid liquid discharged from the metal ion precipitation tank is passed into the acid storage tank. In the present invention, the acid steam is cooled by the jacket heat exchanger and then passed into the acid storage tank, and the metal ion precipitation tank precipitates and separates the metal ions, and discharges the corresponding acid liquid into the acid storage tank for reuse.
Description
technical field [0001] The invention relates to a carbon nanotube purification system for precipitating metal ions, and belongs to the technical field of carbon nanotube production. Background technique [0002] A carbon nanotube is a tubular nanomaterial composed of carbon atoms. Tube walls containing multiple layers of carbon atoms are called multi-walled carbon nanotubes (MWNTs), and those containing a single layer of carbon atoms are called single-walled carbon nanotubes (SWNTs). Carbon nanotubes have attracted the attention of researchers for their unique structure and excellent performance since they were discovered. It has potential application prospects in new conductive / high-strength composite materials, electronic devices, and catalyst carrier materials. [0003] The preparation techniques of carbon nanotubes mainly include: arc discharge method, laser etching method, chemical vapor deposition method, solid phase pyrolysis method, flame synthesis method, glow dis...
