Technical field
The present invention relates to the production field of activated carbon, especially a kind of carbonization-activation integral processing unit (plant) and its processing side
Method.
Background technology
Activated carbon with excellent characterization of adsorption due to being widely used in all trades and professions, it has also become must in production and living
Standby, important industrial products.
The production technology of activated carbon includes mainly carbonizing and activating two steps, wherein the essence carbonized is the heat of organic matter
Solution preocess, including pyrolysis and thermal polycondensation reaction, under the high temperature conditions, the elements such as hydrogen, oxygen contained in organic compound
Composition be decomposed.Carbon atom is constantly cyclized, aromatisation, and the atoms such as hydrogen, oxygen, nitrogen is as a result made constantly to reduce, and charcoal is constantly enriched with, most
Become rich charcoal or pure coal substance by graphitizing process afterwards；The purpose of activation is to be carbonized using steam or chemical substance to remove
The tar material and pyrolysis product in pore structure are accumulated in journey, to improve pore volume（Or surface area）And high-adsorption-capacity
Finished product charcoal.The method of activation mainly uses physical activation method, and also referred to as gas activation, this process is by carbonizing production in height
Warm (800-950 DEG C), passes to vapor, carbon dioxide or air and does the oxidation of selective charcoal with carbonaceous, and hole is deposited in remove
The reaction product in hole.
Wooden active carbon by physical refers to using wooden material as raw material, the activated carbon produced using physical activation method, due to it
Raw material and activator（Water vapour and carbon dioxide）Cleaning, product is pollution-free, enjoys great popularity at present.In the prior art, Ji Husuo
Active carbon by physical production equipment be all that retort and activation furnace are provided separately, separately run.Only several documents are related to
Carbonization-activation integral furnace.For example, 201240852 Y of utility model patent CN disclose one kind can continuously carbonizing, activation production
The converter of physics charcoal, including the charing section converter obliquely placed and be obliquely positioned at downside and mutually concatenated with charing section converter
Activation section converter, charing section converter are respectively equipped with to prevent in stove material to leak and can between being docked with activation section converter
The sealed connecting component of relative rotation.The converter is that charing section and activation section form one from the appearance, actually or charing with
Two reactors of activation are separately run, and it prevents that material leaks in stove and relatively turnable sealed connecting component is also easy to
It is revealed after abrasion.
Patent of invention CN 102311742B disclose a kind of processing method and its work of cellulose industry biomass castoff
Cellulose industry biomass material is fed drying system by process and equipment, by the height that fugitive constituent burning generates in carbonization process
Warm flue gas provides heat, enables raw material drying；Dry feedstock is after gas-solid separator detaches, into carbonization reaction device part heat
Solution charing by the temperature burnt in volatile matter maintenance reactor and carbonizes required heat, in obtained carbonization reaction
Between product entering riser activation furnace, activated carbon is made under the action of Oxidant and activator, the temperature in activation furnace
Degree is the heat that is provided by combustion parts carbonized material to maintain, and the high-temperature gas-solid product of activation, which passes through the preparation system that exchanges heat, to be needed
The steam wanted.This technical process uses the continuously-running duty of complete self-heating, but the drying of raw material and carbonization process are point
Not in drum dryer and（Whirlwind）It is carried out in two reactors of retort, and the activation temperature in riser reactor
It is the heat that is provided by combustion parts carbonized material to maintain, to reduce the yield of activated carbon.
Utility model patent CN 201043140Y disclose a kind of self-heating carbonization-activation integral rotary furnace, by feed inlet, give up
Heat boiler, the first backing ring, transmission gear ring, revolution furnace body, the second support roller, the second backing ring, insulating layer, copy plate, returns at the first support roller
Converter burner, furnace internal-lining, arch in stove, gas-fired hole, steam be added pipe, air inlet hole, stove interior wall, discharge port, steam pipe holder,
Furnace internal-lining support arm, motor, speed reducer are constituted.Material is to be sequentially completed charing and activation during being moved forward in furnace internal-lining,
The combustible gas that charing and activation generate is in revolution burner burning, and negative direction passes through furnace internal-lining and furnace internal-lining branch to the hot gas of burning again
Flue heating rotary furnace internal-lining between arm realizes cycle production run.But the disadvantage of this design structure is to carbonize rank
The fuel gas that section generates, such as H2、CO、CH4, tar etc. has to pass through activation section to go out from liner, these gases cannot be made
For activator, the partial pressure of activator steam can be made to reduce, reduce steam to the activation efficiency of carbonized material and activate the quality of product.
