Description
Technical field
The utility model is related to active carbon production equipment technical fields, and in particular to a kind of production that activated carbon is physically activated
Equipment.
Background technology
There are mainly two types of the methods for producing activated carbon：One is using powderies wood materials such as bamboo and wood bits, with zinc chloride or
Phosphoric acid is the chemical activation method of agent living；Another kind uses vapor to consider charcoal etc. to be worth doing with wooden (bamboo) charcoal, fruit shell carbon, wood (bamboo) as raw material
Or the physical activation method that flue gas is activator.Since China increasingly reinforces forest conservation dynamics, charcoal resource is increasingly
It reduces, in addition, the increase with Activated Carbon Production to shell raw materials requirement amount, the wood of activated carbon is produced with vapor Physical
There is the situation that supply falls short of demand in charcoal, shell carbon feedstock.
Physical activation method is generally divided to charing and activation two steps, first carbonizes raw material at 500 DEG C or so, then with vapor or
The gases such as carbon dioxide are activated at high temperature, and activation process carries out in special activation furnace.Currently, physical activation method is given birth to
The equipment for producing activated carbon generally uses Slapple activating furnace, rotary activated furnace and rake activation furnace.
Slapple activating furnace is the activation equipment that China is introduced the 1950s from the former Soviet Union, by domestic several generations section
Grind personnel continuously improve and it is perfect, technology is highly developed, and Stepple furnace is domestic active carbon from coal production enterprise at present
Owner's activation equipment to be used.Its major advantage is not need external heat source during normal production, the water coal that when activation generates
Gas keeps itself thermal balance of activation furnace by burning, while power consumption is low；The activated carbon of multiple raw material varieties can be produced simultaneously, it is right
The market demand adaptability of domestic and international activated carbon multi items is relatively good；Easily controllable, stable operation, line service amount is small；
Soak time is long, about 72h, and product quality is excellent and uniform；(6- generally can be used in production active carbon from coal to service life of equipment length
9 years).The major defect of Stepple furnace is that single set equipment conversion rate of products is low, and activation furnace is complicated, and the construction period is longer, open,
Blowing out is difficult, replaces raw material and adjusting process process is slow, it is difficult to realize mechanization production, and have to raw material granularity and heap density
Certain requirement.
Using the method for rotary activated furnace preparing active carbon, it is that wood raw material is added from one end of rotary furnace, is turning round
By dry, charing and activation in stove, discharge from the other end of rotary furnace, there is two point defects：First, the air-flow of converter is
It is flowed to discharge end, the feed end temperature of converter is relatively low, and sawdust is not easy to be dried and carbonized, thus cannot generate flammable
Gas, so it is difficult to increase the feed end temperature of converter, converter leading portion fails to play good effect, and sawdusts is waited to turn with converter
Dynamic meet with air when being transported to temperature higher part position is easy to catch fire and reduce the yield of activated carbon, the drying of sawdust, charing and
Activation is all the back segment progress in converter, and region of activation is shorter, and the soak time in converter is just shorter, soak time about 15h, from
And influence the quality of activation effect and product；Second is that being generated when vapor that sawdust generates in the drying process and charing flammable
Mixed gases can reduce the combustibility of fuel gas；Rotary activated furnace energy consumption is big, and single device production capacity is small, technique
Adjusting control is difficult, unstable product quality.
Rake activation furnace using can continuous rotation furnace rake arm and rake teeth stir the material in stove so that material can be equal
It is even to stir, it is come into full contact at high temperature with vapor, ensures that activation is uniform, product quality is stablized.Rake activation furnace be at present most
Advanced activation equipment overcomes the randomness manually stirred and no thoroughness, mechanization, high degree of automation to substantially reduce labor
Fatigue resistance, a worker can operate more activation furnaces, but rake activation furnace is expensive, and equipment investment is big, at home
Popularization degree it is limited, and there are certain abrasion and dusting in stove for material, and there are dead angle, production granularity is small or powdery
The problem of activated carbon is presented is especially prominent.
Utility model content
The purpose of this utility model is to provide a kind of production equipments that activated carbon is physically activated, to solve existing activation
The problems such as stove is expensive, complicated low with using existing activation furnace production activated carbon activation efficiency.

C+2H2O→2H2+CO2Δ H=18kcal
C+H2O→H2+ CO Δs H=31kcal
CO2+ C → 2CO Δs H=18kcal
Can be seen that three reactions from above three chemical equation is the endothermic reaction, i.e., with priming reaction into
Row, the priming reaction regional temperature of activation furnace will gradually decline, if the temperature of activating area is less than 800 DEG C, above-mentioned activation is anti-
It should cannot be normally carried out, so needing in the priming reaction region of activation furnace while being passed through partial oxidative gas to produce with activation
Raw gas-fired additional heat, or by supplementing external heat source, to ensure the activation temperature in activation furnace priming reaction region.

Tracheae 14 is passed through in stove from 1 bottom of activation furnace and is merged with material, material since motion collision forms quality particle not of uniform size,
It controls air pressure in activating chamber 4 and is more than air pressure in separation chamber 9, particle enters separation chamber 9 from activating chamber 4, into the particle of separation chamber 9
It is separated into suspended particulate and deposited particles；Suspended particulate is delivered to high-temperature heat carrier delivery pipe 3 by ash discharge cylinder 6, in air blast
Burning forms flue gas and high-temp solid heat carrier under the action of device, and flue gas is conveyed by blower unit through the second waste heat pipeline 17
To the combustion chamber of waste heat boiler 12, high-temp solid heat carrier enters in activation furnace 1 from 1 top of activation furnace and newly adds as heat source heat conduction
The raw material entered, participates in priming reaction jointly；Deposited particles carry out continuous discharge through discharge port 5；
The high-temperature activation tail gas generated during priming reaction is conveyed from activation offgas outlet 11 through the first waste heat pipeline 13
To the combustion chamber of waste heat boiler 12；High-temperature activation tail gas and heat smoke are delivered to the heat that the combustion chambers burn of waste heat boiler 12 generates
The vapor that amount acts on the generation of waste heat boiler 12 participates in priming reaction as the activator needed for activation.
The energy of the required raw material heating of priming reaction derives from the heating by ignition of suspended particulate, suspended particulate recycling
Enter the raw material that heat conduction in activation furnace is newly added；Generate the waste heat and work that the energy of activator (vapor) burns from suspended particulate
Change the high-temperature activation tail gas displaced in reaction, such as hydrogen, carbon monoxide and methane, these gases are fuel gas.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
