Below by drawings and examples, technical scheme of the present invention will be described in further detail.
The present invention provides a kind of activated carbon fiber electrothermal desorption structures, and this hair is shown as shown in Fig. 1~Fig. 6
A kind of bright preferred embodiments.The present invention improves the regeneration production capacity of activated carbon fiber by simple structure and technique, drop
The regeneration cost of low activity carbon fiber, to expand the application field of activated carbon fiber.
As shown in Figure 1 and Figure 2, the activated carbon fiber electrothermal desorption structure includes being formed by the stacking of activated carbon fiber cloth 2
Activated carbon fiber bed and the electrode mechanism being arranged on a pair of of side end face of the activated carbon fiber bed, the electrode machine

Inside area 1, the conducting resinl area 1 is that activated carbon fiber bed end is at least partially immersed or injects conducting resinl curing molding.
Preferably, the activated carbon fiber cloth 2 is braiding or non-woven acf layer.Since electrode mechanism is arranged
In carbon fiber bed end, carbon fiber bed is formed using the stacking of activated carbon fiber cloth 2, it requires that carbon fiber needs are woven into
Layer structure, such as common activated carbon eyelet fabric.The non-woven form such as activated carbon fiber cloth 2 or activated carbon-fiber felt, equally
It is that layer structure is suitable for making electrode in non-laminated wheat flour.
The conductive metal body 4 is common conductive material.Preferably, the material of the conductive metal body 4 be copper,

The Standard of the fiber filter of activated carbon in use.And the conductive metal of metal bar, wire or metal block form
Body 4 is then capable of increasing the binding force between conductive metal body 4 and conducting resinl area 1, so that electrode mechanism is more secured.
Further, the conducting resinl area 1 by conducting resinl dipping be formed by curing, the conducting resinl be at least silver base conductive glue,
Auri conducting resinl, copper-based conducting resinl or graphite based conducting glue.Preferably due to which the fever that electrode mechanism will meet high current is wanted
It asks, the volume resistivity in the conducting resinl area 1 is less than 10-2Ω·cm.Simultaneously as activated carbon fiber electrothermal desorption structure needs
Desorption by heating is carried out, to guarantee that electrode mechanism works normally, the high temperature resistant temperature in the conducting resinl area 1 is greater than 100 DEG C.It is preferred that
The width on ground, the conducting resinl area 1 is 0.5~2cm, can either guarantee the combination between conducting resinl area 1 and conductive metal body 4
Power, and enable to contact resistance in preferable range, while also making the damage control of activated carbon fiber bed lesser
Range.
The conducting resinl is a kind of adhesive solidified or have certain electric conductivity after dry.Conducting resinl be it is a kind of solidification or
With the adhesive of certain electric conductivity after drying, it is usually mainly to form with matrix resin and conductive filler, that is, conducting particles
Ingredient is combined together conducting particles by the bonding effect of matrix resin, forms conductive path, and leading for material is glued in realization
Electrical connection.Since contacting with each other between conducting particles to form conductive path, keep conducting resinl conductive, it is interparticle in glue-line
Steady contact is as caused by conductive adhesive curing or drying.
For conducting resinl before solidification or drying, conducting particles is existing for separation, not connect continuously each other in adhesive
Touching, thus it is in state of insulation.After conductive adhesive curing or drying, gluing is caused due to the volatilization of solvent and the solidification of adhesive
The contraction of agent volume, making conducting particles each other is in stable continuous state, thus shows electric conductivity.It is conductive in the present invention
Glue uses naturally dry or drying.Preferably, when the conducting resinl is graphite based conducting glue, the conducting resinl area 1 is using baking
Dry curing molding.Due to graphite based conducting glue naturally dry it is difficult to ensure that intensity after solidifying, solidification are needed in certain temperature
Lower progress.Preferably, drying temperature is 60~100 DEG C, and drying time is 30~150min, not only can guarantee solidification intensity, but also energy
Reduce the mass loss and micropore loss of activated carbon fiber at high temperature.
The present invention draws connector such as plain conductor, hard contact etc. by electrode and connect with conductive metal body, avoids work
Property carbon fiber and metal electrode be directly connected to insecure situation, increase electrode application firmness and reliability.Pass through electricity
Connector is drawn in pole, can be powered to activated carbon fiber bed, and activated carbon fiber bed is realized as thermal resistance itself heat production
Desorption and regeneration.
Meanwhile being formed between conductive metal body and activated carbon fiber by conducting resinl and uniformly being connected, avoid traditional approach
The step of metalized is carried out to activated carbon fiber is needed, technology difficulty is reduced, reduces the regeneration of activated carbon fiber
This, is greatly enriched the application field of activated carbon fiber.

The temperature lift-down curve of carbon fiber bed is as shown in figure 5, the electrode mechanism in through the invention heats up, activated carbon fiber bed
Temperature Distribution is more uniform, and maximum temperature is differed with minimum temperature is no more than 10 DEG C, and electrode mechanism of the invention can guarantee to live
Property carbon fiber bed desorption temperature uniformity, electric current contacts one end by fabric itself and electrode and flows directly into the other end, keep away
Exempt to conduct between layers and generates hot-spot phenomenon at contact point, so that temperature is evenly distributed on entire bed, temperature ladder
It spends smaller.
Further, heating and cooling circulation is carried out to activated carbon fiber electrothermal desorption structure, carries out degradation, as shown in fig. 6,
Regeneration desorption is sent out using activated carbon fiber using itself as galvanic couple, electrode mechanism is feasible, safe, and electrode anti-aging property is excellent
Good, with the variation of desorption number, the performance change of itself is stablized.In 280 heating and cooling circulation, activated carbon fiber bed is total
