(CN106185869) 1. Thermal energy multistage recycling carbon nanotube purification system, characterized by comprising a fluid bed, a jacketed heat exchangers, plate heat exchanger, acid tank, stirred tank, mill and two filter press, and the acid fluid reaction bed for carbon nanotube raw material powder for a reaction site, a jacket-type heat exchanger for cooling the fluid bed reaction of the acidic vapor creation, an acid reservoir for storing a jacketed heat exchanger cooling the resultant acid, the press for pressing the liquid in the carbon nanotube crude, stirred tank and the grinder for the carbon nanotubes are homogenously mixed with a non-oxidizing acid solution and crude, crude carbon nanotubes in the metal ion impurities and flushingg it away, Fluid discharged from the jacketed steam into the reaction bed acidic heat exchanger, a jacketed heat exchanger cooling fluid discharged from the acid reservoir into acidic, fluid discharged from the crude carbon nanotubes through the reaction bed filter press press stirred tank and fed onto the processing solution, stirred-tank processing of carbon nanotubes after the crude solution is delivered to through the grinder, the grinder which are obtained through the next filter press processing to yield a finished carbon nanotubes.
