Abstract
The invention discloses a kind of discarded active carbon fiber fabrics/felt recovery reconstruction method, it is characterised in that：Comprise the following steps：Cleaning, dehydration, drying, reconstruction step, discarded active carbon fiber fabrics/felt is turned waste into wealth using this method, the specific surface area of the discarded active carbon fiber fabrics/felt obtained reproduce simultaneously after is than more than original specific surface area, adsorption capacity is greatly improved, reduce the production cost of NACF, resource has been saved, has alleviated discarded active carbon fiber fabrics/felt processing pressure.
Description
Technical field
The present invention relates to a kind of discarded active carbon fiber fabrics/felt recovery reconstruction method, belong to waste recovery reutilization technology
Field.
Background technology
Active carbon fibre denapon its have specific surface area is big, adsorption capacity is strong, desorption rate is fast, acid-fast alkali-proof high temperature resistant, change
Learn stability it is good the features such as, be described as being contemporary latest model, state-of-the-art environmental-protection adsorption material, be widely used in chemical industry,
Environmental protection, electronics industry, medical treatment, food hygiene, shipping industry etc..But because its manufacturing cost is high, expensive is made
About use, and NACF is just no longer had using non-renewable organic matter is plugged after adsorption saturation in its micropore
There is adsorption function, hazardous waste disposal can only be used as.However, this undoubtedly brings huge pressure to environment, while also waste
Resource.
The content of the invention
Discarded active carbon fiber fabrics/felt is reclaimed into reconstruction method it is an object of the invention to provide one kind, will using this method
Discarded active carbon fiber fabrics/felt is turned waste into wealth, while the specific surface area of the discarded active carbon fiber fabrics/felt obtained after reproducing is than super
Original specific surface area is crossed, adsorption capacity is greatly improved, and reduces the production cost of NACF, has saved money
Source, alleviate discarded active carbon fiber fabrics/felt processing pressure.
The technical solution adopted by the present invention is：
A kind of discarded active carbon fiber fabrics/felt recovery reconstruction method, it comprises the following steps：
A, clean
Discarded active carbon fiber fabrics or felt are carried out using compound bodied ferric sulfate of the iron content between 11%-20%
Cleaning, the phosphorus and dust in discarded active carbon fiber fabrics or felt are removed, degrade COD.The waste water obtained after cleaning is by precipitation
After recycle.
B, it is dehydrated
Moisture removal and partial organic substances are removed using dewaterer；
C, dry
Using 10 meters of long meshbeltfurnaces, temperature control in 120-140 degree, guipure transports through Frequency Converter Control, speed control
Dehydrated active carbon fiber fabrics or felt are placed and dried in meshbeltfurnace, removed on NACF in 1-3m/s by system
Partial organic substances, moisture etc.；The flue gas occurred in baking process is up to standard after spray column and Activated carbon fiber adsorption tower processing
Discharge.
D, reproduce
Using 7 meters of long meshbeltfurnaces, temperature control in 860-950 degree, guipure transports through Frequency Converter Control, speed control
In 1-3m/s, active carbon fiber fabrics or felt are placed reproduced in meshbeltfurnace before first toward in stove while being passed through inert gas
And vapor, active carbon fiber fabrics or felt are placed in meshbeltfurnace after emptying oxygen in stove and full of vapor and reproduced,
The active carbon fiber fabrics or felt obtained after reconstruction have extremely strong adsorption capacity.Caused flue gas and water steam in stove in rebuilding course
Gas qualified discharge after spray column and Activated carbon fiber adsorption tower processing.
It is an advantage of the invention that：Discarded active carbon fiber fabrics/felt is turned waste into wealth using this method, while obtained after reproducing
Discarded active carbon fiber fabrics/felt specific surface area than being greatly improved more than original specific surface area, adsorption capacity,
The production cost of NACF is reduced, has saved resource, alleviates discarded active carbon fiber fabrics/felt processing pressure.

And vapor, active carbon fiber fabrics or felt are placed in meshbeltfurnace after emptying oxygen in stove and full of vapor and reproduced,
The active carbon fiber fabrics or felt obtained after reconstruction have extremely strong adsorption capacity.
Flue gas caused by drying course and rebuilding course（Waste gas）And vapor is cleaned through two two level spray columns, drop
Low organic exhaust gas temperature, while partial organic substances are removed, then through Activated carbon fiber adsorption tower adsorption treatment, finally by air inducing
Machine is through chimney qualified discharge；Added simultaneously in the waste water that is recycled in scrubbing tower waste water in cleaning process after precipitation and
A small amount of compound bodied ferric sulfate, makes organic matter precipitate, then by sand filtration, most the row up to standard after carbon fiber adsorption and catalytic combustion afterwards
Put.
