可欠であつた。Prior Art For example, in order to make carbon fibers such as pitch fibers obtained by discharging molten pitch raw materials from a spinning nozzle into activated carbon fibers used in air purifiers, fibers that have been subjected to infusibility treatment are required. Water vapor in the combustion gas ejected from the burner is applied to the fibers, and some of the carbon in the fibers is released as carbon gas, carbon monoxide, hydrogen, etc., making them porous and increasing the specific surface area. There is. During this activation treatment, if oxygen is mixed in the atmosphere of the treatment furnace, the above-mentioned reaction will proceed rapidly, causing the fiber portion to gasify more than necessary, resulting in a decrease in yield, and the surface of the fiber layer being treated. This causes a difference in the reaction between the activated carbon fibers and the fibers in the center, resulting in large variations in the specific surface area of the obtained activated carbon fibers. To prevent this, it has been conventional practice to provide preliminary chambers adjacent to the inlet and outlet of the processing furnace to isolate the outside air, but even so, some amount of outside air cannot be avoided, and there are other problems as well. It has been essential to closely control the mixture ratio of air and fuel to produce the combustion gases.

る。 FIG. 1 shows a schematic side sectional view of the processing apparatus of the present invention. In this device, a net conveyor 2 is installed extending through the center of a processing furnace 1, and a pair of rollers 3a and 4a are provided at an inlet 3 and an outlet 4, respectively, to sandwich the conveyor 2. It is being The interior of the processing furnace 1 is substantially sealed from the outside air by these rollers 3a, 4a.

排出孔である。 A burner 5 is provided on the wall on the exit side of the processing furnace 1, and injects combustion gas such as kerosene or propane gas containing water vapor into the furnace as an activating gas. 6 is a gas discharge hole.
賦活処理される繊維はネツトコンベア２上に適
当な厚さの層７をなすように積載された状態で入
口３から処理炉１内に連続して供給される。 The fibers to be activated are continuously fed into the processing furnace 1 from an inlet 3 while being stacked on a net conveyor 2 so as to form a layer 7 of an appropriate thickness.

ベア２の走行経路の上方に繊維層７の上面と若干
の間隙をあけて、全面に多数の開口９を穿たれた
多孔板８を設けて繊維層上の炉内空間を上下両部
Ａ，Ｂに区分したことにある。 The feature of the device of the present invention is that a perforated plate 8 with a large number of openings 9 formed on its entire surface is provided above the running path of the net conveyor 2 in the furnace with a slight gap from the upper surface of the fiber layer 7. The reason is that the furnace space above the fiber layer is divided into upper and lower parts A and B.

数及び孔径に大きな差が生じ、得られた活性炭素
繊維の品質に変動を生ずる。 In the case of a conventional device in which this perforated plate 8 is not provided, the combustion gas injected from the burner 5 flows inside the furnace from the outlet side to the inlet side, and the fibers exposed on the upper surface of the fiber layer 7 along the way flow. The carbon in the fibers is changed into carbon monoxide or carbon dioxide by the water vapor in the gas and vaporized, forming a porous structure. The combustion gas that comes into contact with these surface fibers is often mixed with air leaked from the seal, and is constantly replaced with fresh air due to convection, so the reaction proceeds rapidly and more carbon than necessary is produced. Vaporize. On the other hand, only the combustion gases captured by the surface fibers that gradually permeate through the fibers reach the fibers in the center of the fiber layer 7 and cause a reaction. It will be relatively slow. Therefore, there is a large difference in the number and diameter of micropores in the fibers caused by the reaction with combustion gas between the surface and center of the layer, resulting in variations in the quality of the obtained activated carbon fibers.
本発明においてはこの繊維層７の上方に若干の
空間Ｂを距てて多孔板８を設置したのでバーナ５

繊維と反応する。この流入ガスは次いで繊維層７
の中心部に拡散して内部繊維と反応するが、前述
のように表層において既に減速されているため従
来装置の場合よりも拡散が容易である。 In the present invention, since the perforated plate 8 is installed above this fiber layer 7 with a slight space B, the burner 5
The gas flow injected from the fiber layer 7 does not directly contact the surface of the fiber layer 7 to form a laminar flow, but is decelerated through the openings 9 of the porous plate 8 and flows into the space B, where it gently reacts with the surface fibers. This inflow gas then flows into the fiber layer 7
It diffuses into the center of the fiber and reacts with the internal fibers, but as mentioned above, the speed is already slowed down at the surface layer, so diffusion is easier than in the case of conventional devices.
この賦活化反応によつて繊維からは一酸化炭

従つて賦活化反応は酸素の存在しない雰囲気下で
行なわれることとなり、前述のような急激な反応
の進行が避けられる。 Due to this activation reaction, gases such as carbon monoxide and hydrogen are released from the fibers, but these released gases remain in the space B separated by the perforated plate 8 and are passed through the entrance and exit port 3 of the furnace 1. It reacts with a trace amount of oxygen in the air that leaks through the seal 4 and inevitably enters the space B, and removes it before it comes into contact with the fibers.
Therefore, the activation reaction is carried out in an oxygen-free atmosphere, and the rapid progress of the reaction as described above can be avoided.
これら一連の効果によつて繊維層の各部におい
てむらのない賦活処理が可能となり、均質な活性
炭繊維が得られる。 A series of these effects makes it possible to perform the activation treatment evenly in each part of the fiber layer, resulting in homogeneous activated carbon fibers.

でステンレススチール等の耐蝕金属又はコージエ
ライト等の鉱物材料で作られることが好ましい。 As a matter of course, the material of the perforated plate 8 must be made of a corrosion-resistant metal such as stainless steel or a mineral material such as cordierite, since it is required to withstand the temperature and chemical action of combustion gas.
又多孔板８の設置高さは繊維層の上面から0.5
mm〜200mmの範囲が好ましい。 Also, the installation height of the perforated plate 8 is 0.5 from the top surface of the fiber layer.
A range of mm to 200 mm is preferred.

By preventing it from flowing, it assists the diffusion of gas into the layer, and also allows volatile gases, carbon monoxide, hydrogen, etc. generated from the fiber layer due to the activation reaction to remain near the surface of the fiber layer. By letting
Since the invading oxygen in the air is removed by reacting with it, the difference in the degree of activation reaction between the fibers on the surface and the center of the fiber layer is reduced, resulting in a homogeneous product. Is possible.

A carbon fiber activation treatment method in which a fiber layer to be treated is continuously advanced into a treatment furnace and activated by contacting with water vapor in an activation gas, the method comprising: The upper surface of the fiber layer in the middle is covered with a perforated plate with a space in between, thereby preventing the activation gas from directly reaching the upper surface of the fiber layer and flowing along it. A method for activating carbon fibers, characterized in that the activation gas enters the space using only the holes in the perforated plate as an entry path, and remains for a while on the upper surface of the fiber layer. 2. The method according to claim 1, wherein the carbon fiber is a pitch carbon fiber. 3. A carbon fiber processing furnace consisting of a net conveyor that runs from the inlet to the outlet of the processing furnace, and a processing furnace in which the inlet and outlet are substantially airtightly sealed and is equipped with a burner that injects activating gas into the furnace. A continuous processing device for activation, in which a perforated plate with perforations on the entire surface is arranged above the running path of the net conveyor, and the upper surface of the carbon fiber layer stacked on the net conveyor and the perforated plate are arranged. A predetermined space is maintained between the carbon fiber layers, and the activation gas enters the space only through the holes in the perforated plate and remains on the upper surface of the carbon fiber layer for a while. Carbon fiber activation processing equipment.
