A kind of carbonization-activation integral processing unit (plant) and processing method thereof
Technical field
The present invention relates to the production field of activated carbon, especially a kind of carbonization-activation integral processing unit (plant) and processing side thereof Method.
Background technology
Activated carbon is widely used in all trades and professions owing to having the characterization of adsorption of excellence, it has also become must in productive life Standby, important industrial products.
The production technology of activated carbon mainly includes carbonization and two steps of activation, and wherein the essence of carbonization is organic heat Solution preocess, reacts including pyrolysis and thermal polycondensation, under the high temperature conditions, and the element such as hydrogen contained in organic compound, oxygen Composition be decomposed.Carbon atom is constantly cyclized, aromatisation, and result makes the atoms such as hydrogen, oxygen, nitrogen constantly reduce, and charcoal is constantly enriched with, After become rich charcoal or pure coal substance through graphitizing process;The purpose of activation is to utilize steam or chemical substance to remove carbonization Journey accumulates in the tar material in pore structure and pyrolysis product, to improve pore volume (or surface area) and high-adsorption-capacity Finished product charcoal.The method of activation mainly uses physical activation method, also referred to as gas activation, and this process is in height by carbonizing production Temperature (800-950 DEG C), passes to steam, carbon dioxide or air and carbonaceous and does the oxidation of selectivity charcoal, is deposited in hole to remove The reaction product in hole.
Wooden active carbon by physical refers to wooden material as raw material, uses the activated carbon that physical activation method produces, due to it Raw material and activator (water vapour and carbon dioxide) cleaning, product is pollution-free, enjoy great popularity at present.In prior art, Ji Husuo It is all retort and activation furnace is provided separately, separately run that some active carbon by physical produce equipment.Only have several documents to relate to Carbonization-activation integral furnace.Such as, utility model patent CN 201240852 Y disclose one can continuously carbonizing, activation produce The converter of physics charcoal, the carbonization section converter placed including inclined shape and on the downside of being obliquely positioned at and concatenate mutually with carbonization section converter Activation section converter, is respectively equipped with to prevent material in stove from leaking and can between its carbonization section converter and activation section converter joint Seal connector in relative rotation.This converter from being carbonization section in appearance and activation section forms one, actually or carbonization with Activate two reactors separately to run, and it prevents material in stove from leaking and relatively turnable seal connector is also easy to Reveal after abrasion.
Patent of invention CN 102311742B discloses processing method and the work thereof of a kind of cellulose industry biomass castoff Process and equipment, feeds drying system by cellulose industry biomass material, by the height produced from fugitive constituent burning in carbonization process Temperature flue gas provides heat, makes raw material be dried;Dry raw material, after gas-solid separator separates, enters carbonization reaction device part heat Solve carbonization, rely on the temperature in burning volatile matter maintenance reactor and the heat required for carbonization, in obtained carbonization reaction Between product enter riser activation furnace, under the effect of Oxidant and activator prepare activated carbon, the temperature in activation furnace Degree is that the heat provided by combustion parts carbonized material is maintained, and the high-temperature gas-solid product of activation is needed by heat exchange preparation system The steam wanted.This technical process uses the continuously-running duty of complete self-heating, but being dried of raw material with carbonization process is point Do not carry out in drum dryer and two reactors of (whirlwind) retort, and the activation temperature in riser reactor It is that the heat provided by combustion parts carbonized material is maintained, thus reduces the productivity of activated carbon.
Utility model patent CN 201043140Y discloses a kind of self-heating carbonization-activation integral rotary furnace, by charging aperture, gives up Heat boiler, the first support roller, the first backing ring, transmission gear ring, revolution body of heater, the second support roller, the second backing ring, heat-insulation layer, copy plate, return Arch in converter burner, furnace internal-lining, stove, gas-fired hole, steam addition pipe, fresh air inlet, stove interior wall, discharging opening, steam pipe support, Furnace internal-lining support arm, motor, reductor are constituted.Material be move forward in furnace internal-lining during be sequentially completed carbonization and activation, The combustible gas that carbonization and activation produce is in revolution burner burning, and the hot gas of burning opposite direction again is propped up with furnace internal-lining through furnace internal-lining Flue heating rotary furnace internal-lining between arm, it is achieved cyclic production is run.But the disadvantage of this design structure is carbonization rank The fuel gas that section produces, such as H2、CO、CH4, tar etc. have to pass through activation section and could go out from inner bag, these gases can not be made For activator, the dividing potential drop of activator steam can be made to reduce, reduce steam to the activation efficiency of carbonized material and activation product quality.
