Definitions
- the present invention relates to a carbon nanotube production apparatus for producing carbon nanotubes such as carbon nanotubes and carbon fibers by a gas phase flow method.
- Carbon nanotubes are crystalline carbon having a structure in which a thin layer of graphite crystal is rounded into a cylindrical shape. That is, the carbon source constituting the carbon nanotube forms a planar or curved graphene sheet formed by arranging six-membered rings of carbon molecules like a tortoiseshell pattern, and one direction of such a graphene sheet A carbon nanotube is a rounded cylindrical shape.
- a carbon nanotube has a diameter of 0.4 nm to several tens of nm, and its length is generally several tens to several thousand times longer than the diameter.
- Such carbon nanotubes are attracting attention from many fields because of their high strength, excellent electrical conductivity, thermal conductivity, and slidability. And in order to be able to provide this carbon nanotube at a lower price, more efficient carbon nanotube manufacturing technology is required.
- This gas phase flow method is a method for producing carbon nanotubes by flowing a carbon-containing raw material and a catalytic metal together with a carrier gas in a high-temperature furnace, and thermally decomposing and synthesizing a raw material such as a carbon source in the gas phase. is there. Since this gas phase flow method is a manufacturing technique suitable for mass production, many improved techniques have been proposed.
- the discharge pipe arranged on the downstream side of the reaction pipe may be blocked by the carbon nanotubes. That is, normally, the carbon nanotubes generated in the reaction tube flow downstream, and are finally discharged to the outside through a discharge tube disposed on the downstream side of the reaction tube.
- carbon nanotubes may adhere to the inner surface of the discharge pipe during the transition process. If even a small amount of carbon nanotubes adheres to the inner surface of the discharge tube, this time, new carbon nanotubes are more likely to adhere (easy to be caught) to the carbon nanotubes attached to the inner surface, and the carbon nanotubes stagnating on the spot. The amount increases rapidly.
- the discharge pipe may be blocked with carbon nanotubes.
- the driving of the manufacturing apparatus is periodically stopped to remove the carbon nanotubes adhering to the inner surface of the discharge pipe.
- Such periodic shutdown of the manufacturing apparatus and the removal work of the carbon nanotubes have caused problems such as a decrease in the production efficiency of the carbon nanotubes and an increase in the burden on the operator.
- Japanese Patent Publication No. 2001-73231 and Japanese Patent Publication No. 2001-115342 disclose techniques for preventing carbon nanotubes from adhering to the inner surface of a reaction tube.
- these techniques are intended to prevent adhesion to the reaction tube and cannot prevent adhesion to the discharge tube.
- various other improved technologies for the gas phase flow method have been proposed, but at present, there is no technology that can appropriately prevent the carbon nanotubes from adhering to and blocking the discharge tube, and the production efficiency of carbon nanotubes is reduced. It was difficult to improve.
- an object of the present invention is to provide a carbon nanotube production apparatus that can further improve the production efficiency of carbon nanotubes.
- the carbon nanotube production apparatus of the present invention is a carbon nanotube production apparatus for producing carbon nanotubes by a gas phase flow method, comprising a reaction tube, a supply means for supplying a carbon-containing raw material from the upstream side of the reaction tube, and the reaction Heating means for forming a reaction field for generating carbon nanotubes by pyrolyzing the carbon-containing raw material inside the reaction tube by heating the tube, and disposed downstream of the reaction tube, And a swirling flow generating means for generating a swirling flow that flows from the inner surface to the inner surface of the discharge tube.
- the swirling flow generating means includes a plurality of nozzles that are installed on the inner side surface of the discharge pipe and jet gas in a direction deflected from the center of the discharge pipe.
- the plurality of nozzles are preferably arranged at equal intervals in the circumferential direction of the discharge pipe.
- it is desirable that the nozzle is installed in the vicinity of the upstream end of a low temperature region lower than the heat resistant temperature of the nozzle in the discharge pipe.
- a swirling flow that flows from the inner surface to the inner surface is generated inside the discharge pipe.
- the swirling flow isolates the carbon nanotubes from the wall surface and transports them to the central portion of the discharge pipe, thereby effectively preventing the carbon nanotubes from adhering to the inner side surface and thus blocking the discharge pipe. . Even if the carbon nanotubes adhere to the inner surface, the carbon nanotubes are peeled off by the swirling flow. As a result, the carbon nanotube production apparatus can be operated continuously, and the production efficiency can be improved.

However, normally, at the end of the reaction tube 12, the specific area of heat dissipation is larger than that in the center, and the temperature tends to decrease. In other words, a temperature distribution is generated in the reaction tube 12 such that the temperature decreases as it approaches both ends. Although the boundary of the temperature distribution cannot be clearly defined, a first intermediate temperature region Ea that is lower than the generation temperature is near the upstream end of the reaction tube 12, and the generation temperature is near the downstream end of the reaction tube 12. A lower second intermediate temperature region Ec is formed.

A heating device 14 may be provided.
- the raw material liquid is supplied to the reaction tube 12 by the raw material supply mechanism 18.
- the raw material supply mechanism 18 includes a raw material tank 20, a supply nozzle 26, a raw material supply pipe 24, and a pump 22.
- the raw material tank 20 is a container for storing a raw material liquid.
- the raw material liquid is a liquid in which a carbon-containing liquid, an organometallic catalyst, a reverse micelle particle containing the same, a catalyst auxiliary agent, or the like is mixed.
- This raw material liquid is sent to a plurality of supply nozzles 26 through a raw material supply pipe 24.
- the feed of the raw material liquid is performed by a pump 22 that is driven and controlled by a control unit (not shown).
- the supply nozzle 26 is a nozzle that atomizes the raw material liquid sent from the raw material tank 20 and supplies it to the reaction tube 12.
- the supply nozzle 26 is installed at the upstream end of the reaction tube 12, and its tip protrudes from the upstream end surface of the reaction tube 12 into the reaction tube 12 so as to reach the reaction region Eb.
- the number of the supply nozzles 26 is not specifically limited, Single may be sufficient and three or more may be sufficient.
- the carbon source, the organometallic catalyst, and the catalyst auxiliary agent contained in the raw material liquid are evaporated. Then, the organometallic catalyst is thermally decomposed to generate catalyst fine particles.
- a carbon source comes into contact with the generated catalyst fine particles, a carbon hexagonal network surface is formed on the surface of the catalyst fine particles, and a cylindrical graphene sheet is formed. Then, in the process in which the catalyst fine particles descend in the reaction tube 12, the graphene sheet gradually grows in the length direction, so that carbon nanotubes are generated.
- a carrier gas introduction pipe 28 is provided around the supply nozzle 26.
- the introduction pipe 28 is connected to a gas supply source through a gas supply pipe.
- the carrier gas is a gas that does not affect the carbon nanotube synthesis reaction, and transfers the raw material and the carbon nanotubes in the production process to the downstream side.
- the supply mode of the raw material and the carrier gas described here is an example, and supply of the raw material and the carrier gas is possible as long as carbon nanotubes can be generated by a gas phase flow method that causes a synthesis reaction of the raw material in the gas phase.
- the aspect may be changed as appropriate.
- the raw material may be supplied in a gaseous state instead of being supplied in a liquid state (raw material liquid).

- a collection tank is provided below the discharge pipe 32, and the generated carbon nanotubes are collected and collected.
- the discharge pipe 32 has been easily clogged with carbon nanotubes. That is, the carbon nanotubes that have flowed up to the discharge pipe 32 should pass through the discharge pipe 32 and be discharged into the collection tank. However, some carbon nanotubes adhere to the inner surface of the discharge pipe 32 and stay there. If there is a carbon nanotube attached to the inner surface of the discharge pipe 32, another carbon nanotube is now easily caught on the attached carbon nanotube. Then, another carbon nanotube is newly caught on the caught carbon nanotube. Eventually, a large number of carbon nanotubes are entangled with each other and stay in place, and as a result, the inside of the discharge pipe 32 may be blocked with the carbon nanotubes.
- Such clogging with carbon nanotubes may also occur in the reaction tube 12.

- a slight taper 32a is formed in the vicinity of the upstream end (end portion on the reaction tube 12 side) of the discharge pipe 32 so that the inner diameter becomes smaller as it approaches the upstream end, as shown in FIG.
- the vicinity of the upstream end of the discharge pipe 32 is formed to be slightly thicker than the downstream side. By forming the vicinity of the upstream end thick in this way, it becomes easy to stably hold a nozzle 34 described later.

- Each nozzle 34 is connected to a gas supply source (not shown), and discharges gas into the discharge pipe 32 in accordance with an instruction from the control unit.
- the gas type is not particularly limited as long as the gas does not deteriorate or alter the synthesized carbon nanotube. Therefore, the same kind of gas as the carrier gas may be used, or nitrogen may be used. Further, the wind pressure (flow velocity) of the gas discharged from each nozzle 34 has such a magnitude that it can be transferred without adhering carbon nanotubes.
- the nozzle 34 is fixed to the side wall of the discharge pipe 32 in a direction deflected with respect to the center O of the discharge pipe 32 as shown in FIG. In this case, the distribution directions of all the nozzles 34 are aligned in the same direction. Further, the plurality of nozzles 34 are equally arranged in the circumferential direction.

- each nozzle 34 is fixed facing obliquely downward. Thereby, the gas heading obliquely downward is released from each nozzle 34, and the carbon nanotubes are positively transferred to the downstream side by the gas.
- the tilt angle of each nozzle can be adjusted as appropriate depending on the number of these nozzles and the like. However, when six nozzles are arranged as in this embodiment, the tilt angle is preferably about 10 degrees, but ⁇ 10 degrees. It may be increased or decreased within a range.
- each nozzle 34 is provided in a position as close to the upstream end as possible in the discharge pipe 32.
- the upstream end of the discharge pipe 32 is connected to the high-temperature reaction pipe 12 and is often relatively hot. That is, as shown in FIG. 1, a second intermediate temperature region Ec having substantially the same temperature as the vicinity of the downstream end of the reaction tube 12 is formed near the upstream end of the discharge tube 32.
- the second intermediate temperature region Ec is in a considerably high temperature state (several hundred degrees Celsius) even if not as high as the reaction region Eb in which the carbon nanotube synthesis reaction is performed.
