Description

Gasification furnace module and fullerene preparation device

Technical Field

The application relates to the technical field of fullerene preparation, in particular to a gasifier module and a fullerene preparation device.

Background

At present, with the development of the technology for preparing fullerene, a plurality of methods for preparing fullerene exist. Most methods consume graphite rods or other methods to obtain fullerene carbon powder by arc discharge in a closed gasifier, and cool and store the synthesized fullerene carbon powder, which are all completed in the gasifier.

When carbon powder containing fullerene is produced, carbon dust containing fullerene needs to be synthesized by an arc high-temperature gasification carbon rod, and the produced carbon powder needs to be cooled and stored. There is a certain contradiction between realizing high temperature and cooling protection in a gasification furnace. The synthesis of fullerene requires a high-temperature environment, and a high-temperature region centered on an arc is always present during the synthesis. The resulting fullerenes need to diffuse rapidly away from the arc-centered high temperature region and into a cool region for effective storage. The carbon powder of fullerene is synthesized in an electric arc area and needs to be cooled by diffusion to the periphery, and the diffusion process is relatively slow in a stable space, so that the carbon powder cannot leave a high-temperature area quickly.

The gasification furnace cools the inner wall of the gasification furnace by the introduced cooling water, and a cooled region is formed near the inner wall of the gasification furnace, and the size of the region is related to the size of the space inside the gasification furnace. Because the high-temperature area with the electric arc as the center exists all the time in the synthesis process, when the internal space of the gasification furnace is increased to enlarge the cooling area, the distance of carbon powder diffused to the cooling area is increased, the carbon powder is not beneficial to fast leaving, and when the distance of the compressed carbon powder diffused to the cooling area in the internal space of the gasification furnace is reduced, the cooling effect is reduced. This makes it difficult to satisfy the conditions in the same gasifier at the same time.

The electrode assembly 20 is at least partially disposed within the first space 100.

By applying the technical scheme of the embodiment, the electrode assembly 20 reacts in the first space 100, and the product generated by the reaction is rapidly cooled by the heat exchanger 12, so that the yield of the product can be improved. The heat exchanger 12 divides the inner space of the gasification furnace 11 into a first space 100 and a second space 200, and the temperature in the second space 200 is lower than that in the first space 100, so that the generated product can be cooled rapidly, and the yield of the product can be improved.

Because the space of the gasification furnace is smaller than the volume in the diffusion cooling bin, the data detected by the pressure sensor of the diffusion cooling bin and the pressure sensor of the gasification furnace shows that the pressure in the gasification furnace is higher than the pressure in the diffusion cooling bin, so that the airflow containing carbon powder in the gasification furnace can quickly enter the diffusion cooling bin. The diffusion cooling bin is isolated from the gasification furnace through the reducing air pumping block, and a high-temperature region taking the electric arc as the center cannot enter the diffusion cooling bin, so that the cooling effect in the diffusion cooling bin is ensured. The diffusion cooling bin is in a vacuum state, and the pressure is lower than the pressure in the gasification furnace. After the gas containing the carbon dust enters the diffusion cooling bin, the gas can be rapidly diffused for cooling. This provides an effect of accelerating the rapid exit of the toner and rapid cooling, thereby better preserving the fullerene after the formation. The diameter of the middle hole of the variable diameter air extraction block is increased by adjusting the pressure in the gasification furnace and the pressure in the diffusion cooling bin, so that the resistance of the middle hole to the carbon powder is reduced while the pressure difference of two spaces exists. Wherein, the diameter of the middle hole of the reducing air pumping block 5 is more than 5mm.

The application also provides a device is prepared to fullerene. The fullerene preparation device further comprises a gasification furnace module, and the gasification furnace module is the gasification furnace module.

Usually only one or a few graphite rod electrodes can be installed at a time as consumable graphite rod electrodes. During the operation, carbon dust containing fullerene is synthesized, and since the synthesis furnace (gasification furnace) is sealed, the carbon dust adheres to the inner wall of the synthesis furnace, the surface of the insulating member, and the like. As graphite is a conductive material, with the continuous increase of carbon dust, the carbon dust attached to each part in the synthetic furnace is continuously increased, and the carbon dust attached to the surface of an insulating part (an insulating sleeve) is also continuously increased, so that the insulation failure is caused, and the equipment cannot normally operate. Because the efficiency of preparing fullerene by an electric arc method is low, only one or a plurality of graphite rods can be consumed each time, the quantity of generated carbon powder is not large, the insulation failure time can be properly slowed down by the methods of increasing the labyrinth insulation for isolation and the like through the surface area of an insulating part, but the insulation failure condition can occur after the quantity of the carbon powder is increased. After the insulation fails, the synthesis furnace needs to be disassembled, the insulation part and the synthesis furnace inside are cleaned, and after the cleaning is finished, a series of work such as closing the synthesis furnace, vacuumizing, filling inert gas and the like is carried out again, so that normal synthesis work can be carried out. The process can be carried out only after the temperature in the synthesis furnace reaches the room temperature, so that a large amount of time is wasted, the production efficiency is reduced, and the production cost is increased.
