Activated carbon production apparatus and its production method.
Background technique
Active carbon is a kind of very tiny carbon granule, there is very big surface area, and there are also more tiny holes in carbon granule ---
Capillary.This capillary has very strong adsorption capacity, since the surface area of carbon granule is very big, so can fill with gas or impurity
Tap touching.Encounter capillary when these gases or impurity to be adsorbed, aseptic.The characterization of adsorption of active carbon is producing it
In life using more and more, currently, active carbon is applied in sewage treatment and household mostly, in household, active carbon is normal
For air cleaning, newly spruce up except formaldehyde, Chu Gui Chou Ti refrigerator etc. eliminate the unusual smell, automobile eliminates the unusual smell.
As pursuit of the people to quality of life and body health level is higher and higher, active carbon use increasingly by
The demand of the attention of people, active carbon is also increasing.
The preparation method of active carbon has physical method and two kinds of chemical method.Physical method preparing active carbon can only use natural activity
Charcoal smashing and grinding is produced, but few natural active carbons, and natural carbon is mainly coal and graphite, but does not have adsorbing separation
The activity of substance.Therefore, physical method prepare active carbon can not large-scale popularization.Producing activated carbon by chemical method be by organic matter (usually
Lignocellulosic material) it heats destructive distillation in the absence of air conditions and obtains, usually quality is loose, and specific gravity is small, water imbibition and absorption
Property is good.
Currently, chemical method (phosphoric acid method) the production existing technique of active carbon is commonly, soaked after wood raw material drying with phosphoric acid
Stain carries out charing process into retort, is activated later into activation converter, activation furnace generallys use internal heat type flue gas
Heating.Its there are the problem of mainly have, due to for internal heat type flue gas heating, for guarantee enough heats, flue tolerance are provided
Larger, high-temperature flue gas is contacted with material can take a large amount of phosphoric acid out of, cause discharge outlet phosphorus acid content exceeded；And flue gas emissions
For temperature generally at 150-250 DEG C, heat causes larger waste.
Summary of the invention
In view of the above shortcomings of the prior art, the work that the object of the present invention is to provide a kind of structures is simple, production cost is low

By using above scheme, of the invention a kind of activated carbon production apparatus and its production method and prior art phase
Than having the technical effect that
1, solve environmental issue: active carbon by chemical method production is activated using internal heat type, due to activator to be added (phosphoric acid), because
When this exhaust emissions environment can be polluted with a large amount of phosphoric acid gas.The present invention using dipping after activated carbon raw material with
Tail gas contact, absorbs the phosphoric acid in exhaust gas, so that finally discharging without phosphoric acid.
2, solve energy consumption problem: the gas after activation furnace is discharged into dry plasticizing apparatus, increases low temperature drying step,
It is sufficiently impregnated phosphoric acid in activated carbon raw material hole, while most of moisture is evaporated, so that the load of activation procedure was big later
It reduces greatly, not only shortens the time of activation, while reducing and the high-temperature gas air quantity of activation heat source is provided.In addition, activation
The flue gas that fire grate is put directly is contacted with the activated carbon raw material after dipping, does not only reach environmentally friendly purpose, and flue gas heat is utilized
To evaporate the moisture in activated carbon raw material.
3, it saves raw material: being intercepted, serve as next by activated carbon raw material by the phosphoric acid that the high-temperature gas of activation furnace is taken out of
The activator of batch materials, phosphoric acid are fully utilized, and greatly reduce the consumption of phosphoric acid.
4, it improves activated carbon product quality: increasing low temperature drying process, so that phosphoric acid is fully penetrated in activated carbon raw material hole
Gap in activation process more thoroughly not only increases activated carbon adsorptive capacity, while reducing ash of active carbon.
