(ACF) specific surface area is up to 1000~1600m2/ g, micro pore volume are up to 90%, and micropore size is 10~40A.
But activated carbon fiber can only temporarily adsorb pollutant, since there are adsorption saturation states for adsorbent, reach saturation
The adsorbent of state no longer adsorbs pollutant.Activated carbon fiber regeneration refers to either physically or chemically not destroying active carbon
Or under the premise of activated carbon fiber original structure, the adsorbate being adsorbed on active carbon or activated carbon fiber is removed, it is extensive
Its multiple absorption property, to achieve the purpose that reuse.According to existing technology, regeneration is typically all preferred high at present
The advantages of temperature heating method of reproduction, high-temperature heating method of reproduction, is that it can decompose many kinds of substance in regenerative process, and regenerative environ-ment is good
It is good, to become main regeneration method.Also in two kinds of situation, one kind is directly using hot to the high-temperature heating method of reproduction of mainstream at present
Air desorption, energy consumption is high, requires device structure also high；Another kind is directly to regard activated carbon fiber itself as thermal resistance,
It is powered so that activated carbon fiber self-heating realizes desorption.
In activated carbon fiber electro-thermal regeneration, it is attached in bed end face that direct-electrifying usually requires activated carbon fiber fever
It is powered on pole.But activated carbon fiber is flexible material, easily-deformable, there are contact resistances between electrode and activated carbon fiber, and live
Property carbon fiber end face can not it is substantially flat, electrode can not be completely attached to activated carbon fiber end face, cause localized contact resistance
It is excessive.
And another feasible mode is to pass through surface treatment (such as evaporation deposition method, thermal spraying in activated carbon fiber end face
The modes such as method, electroless plating method or ion plating method) attachment certain thickness metal coating, and then form electrode.But in active carbon fiber
Tie up end face formed metal coating cost it is extremely high, not only technique is extremely complex, need specific professional equipment (such as PVD equipment,
CVD equipment), and cost is very high.So the production capacity of regeneration activity carbon fiber is seriously limited using the above method, and by
Application field and direction are also seriously limited in high costs.
Summary of the invention
The purpose of the present invention is to propose to a kind of activated carbon fiber electro-thermal regeneration unit, by simple structure and technique,
