Mechanical grading manually is moved out, is packed and stored, conventional regeneration process for preparing activated carbon is seriously polluted, labor intensive, high energy consumption, quality
It is low and unstable.
Summary of the invention
The technical problem to be solved in the present invention is that the production method energy consumption of regenerated carbon in the prior art is high, artificial
It is at high cost, and regenerated quality of activated carbon is low, thus propose a kind of low energy consumption, environmental protection, and mass greater activity can be produced
The production method of the regenerated carbon of charcoal.
For this purpose, a kind of Regeneration active carbon production method of the invention, successively the following steps are included:
A. waste active carbon is packed into the holding vessel of stainless steel, makes to store using the gas in evacuator extraction holding vessel
It is in negative pressure in tank；
B. moisture content is put into numerical control high temperature smoldering furnace in the waste active carbon of 30-40%, is added at a temperature of 100-120 DEG C
It is 2-4 hours hot；
C. control numerical control high temperature smoldering furnace was gradually heated to 700-850 DEG C from 130-140 DEG C in 3-4 hours；
D. oxidizing gas is imported in numerical control high temperature smoldering furnace and carries out gasification reaction, and temperature is controlled at 800-850 DEG C, protected
It holds 5-7 hours, obtains activated carbon；The high-temperature tail gas that the step generates, again in steps for importing b；
E. active carbon is cooled by water-cooled process system to 30 DEG C for 5-6 hours；
F. the active carbon after cooling cleaned, be classified, the equipment that the step is mainly used have airslide conveyor, point
Grade machine, cyclone collector, pulse collector and mixed charcoal machine；
G. it will be packed and stored after the active carbon finished products vacuum compression after classification；
Wherein, a large amount of low temperature exhaust gas generated in step b, 40-60% imported into firing stage and activation stage, remainder
Divide and imports exhaust treatment system；
Heat caused by exhaust treatment system high-temp combustion and by heat caused by water-cooled process system back to
It is preheated in step b or c or d.
Above-mentioned Regeneration active carbon production method, wherein the temperature in step b is 105-110 DEG C, and heating time is
2.5-3.5 hour.
Above-mentioned Regeneration active carbon production method, wherein control the numerical control high temperature smoldering furnace in 3.5 hours from 135
DEG C it is gradually heated to 800 DEG C.
The present invention has the following technical effect that compared with prior art
Above-mentioned Regeneration active carbon production method of the invention, wherein activation stage is mainly completed in high temperature smoldering furnace, from
Dynamicization degree is high, has saved cost of labor, while the regenerated carbon quality produced is guaranteed, energy consumption is lower, reduces dirt
Dye.
Specific embodiment
A kind of Regeneration active carbon production method of the embodiment of the present invention, successively the following steps are included: a. fills waste active carbon
Enter in the holding vessel of stainless steel, is made in holding vessel using the gas in evacuator extraction holding vessel in negative pressure；B. by moisture content
It is put into numerical control high temperature smoldering furnace in the waste active carbon of 30-40%, is heated 2-4 hours at a temperature of 100-120 DEG C；C. number is controlled
Control high temperature smoldering furnace was gradually heated to 700-850 DEG C from 130-140 DEG C in 3-4 hours；D. it is led in numerical control high temperature smoldering furnace
Enter oxidizing gas and carry out gasification reaction, temperature controls at 800-850 DEG C, kept for 5-7 hours, obtain activated carbon；The step
Suddenly the high-temperature tail gas generated, again in steps for importing b；E. active carbon was cooled by water-cooled process system through 5-6 hours
To 30 DEG C；F. the active carbon after cooling cleaned, be classified, the equipment that the step is mainly used have airslide conveyor, point
