Continuous combustion production equipment for synthesizing tonnage fullerene and synthesis method thereof

Abstract

The invention discloses continuous combustion production equipment for synthesizing tonnage fullerene and a synthesis method thereof, and relates to the fullerene. The continuous combustion productionequipment is provided with a gas supply and flow control system, a liquid supply and flow control system, a vaporization and preheating system, a combustion furnace body, a combustor, an atomizer, anignition system, a filter tank, a product collecting system, a vacuum control system, a vacuum measurement and display device, and a circulating water-cooling system; the synthesis method comprises the following steps: opening a gas fuel supply pipeline, adjusting to appropriate flow through a mass flow meter, placing a metal electrode point of the ignition system adjacent to a gas fuel outlet ofthe combustor, turning on the ignition system, and enabling the electric spark to ignite the gas to produce flame; starting a vacuum pump set; opening a liquid raw material supply pipeline; and adjusting to the appropriate flow through a constant flow pump; and adjusting the system pressure so as to maintain the system pressure to be less than 5000Pa. by adopting a way of diffusing the combustion, the interference resistance and the fluctuation resistance of the system are stronger, and the synthesis process is safer and more stable.

Description

technical field [0001] The invention relates to fullerenes, in particular to a combustion device for synthesizing ton-level fullerenes by means of diffusion combustion and a synthesis method thereof. Background technique [0002] Fullerene is the third allotrope of carbon besides graphite and diamond. Since its discovery in 1985, it has become a research topic due to its unique hollow spherical cage structure and strong electron affinity and other physical and chemical properties. hotspots. Fullerenes have great application potential and value in solar cells, catalysis, biomedicine and other fields. The development and application of fullerenes is of great significance to the progress of science and technology, and increasing the production capacity of fullerenes and reducing the production cost of fullerenes are the keys to achieve better applications and faster development. [0003] The synthesis methods of fullerene mainly include laser evaporation graphite method, resi...

Problems solved by technology

[0006] The process equipment disclosed in Chinese patent CN101012056A is made of glass, and there is a safety hazard that the glass is easy to burst, and the output is low; the process equipment disclosed in Chinese patent CN101503188 is made of stainless steel, but the combustion must be stopped when collecting the product, and continuous synthesis cannot be realized; The process equipment disclosed in CN201210123308 can realize the continuous production of fullerenes, but due to the unbalanced air pressure when the collection system is switched, there is a stability problem in continuous production, and the conversion rate of fullerenes by combustion synthesis is also low
