Change stove uniformly to heat, until vaporization terminates；
3rd step, vaporization open the discharging opening of stifling gasification burner after terminating, and fumigate the rough Chinese hawthorn seed charcoal in gasification burner
Into after intermediate bin, immediately pass through the second helical feeder and rough Chinese hawthorn seed charcoal is conveyed into activation furnace；
4th step, activated carbon production system work, the stifling vaporization extraction system of fruit stone and activated carbon system of processing are closed；Will
The material inlet of activation furnace is closed, and gas outlet is opened；Gas entry is opened, firing up, reach activation in-furnace temperature
800 DEG C -1100 DEG C, while steam entry is opened, it is passed through 300 DEG C -450 DEG C of superheated vapour；Rough Chinese hawthorn seed charcoal is equal
Preceding 1/3 period of even heating total time, evaporation smoke valve is opened, activation air valve is closed, and high temperature pyrolysis gas phase product passes through
Pipeline where evaporating smoke valve enters the condensation tube inlet of the second condenser, and the second pump, which is opened, makes the second water chiller work, high temperature
Fractional oil of haw kernel stoste and not condensable combustible gas are obtained after pyrolysis gas-phase product is condensed, and fractional oil of haw kernel stoste is along VERTICAL TUBE
Road is instilled in secondary medicine original fluid container, and not condensable combustible gas enters returning for stifling gasification burner in the presence of the 3rd blower fan along pipeline
Gas port；Rough Chinese hawthorn seed charcoal uniformly heats rear 2/3 period of total time, and activation air valve is opened, and evaporation smoke valve is closed, high
Warm solution gas-phase product is discharged from the gas outlet of activation furnace, is entered in the presence of the 3rd blower fan by pipeline where activating air valve
The gas returning port of stifling gasification burner；To the uniform heating of rough Chinese hawthorn seed charcoal until material becomes loose, start to switch to kermesinus, and emit
Go out a large amount of white cigarettes, activation terminates, and obtains activated carbon.
Compared with prior art, beneficial effect of the present invention is：
(1) present invention co-producing active carbon while fractional oil of haw kernel is produced, realizes the comprehensive utilization of resource, avoids only
Focus on production single product and ignore the economic value of byproduct.Chinese hawthorn seed is in the rough Chinese hawthorn seed charcoal base after stifling vaporization
Originally original size is maintained, high quality active carbon can be prepared, but in traditional production process, most Chinese hawthorn seed profit
A certain specific product is only produced with equipment or is only focused in pyrolytic process in itself, enterprise lacks multi-joint to the progress of whole thermal decomposition products
The technology and system of comprehensive utilization are produced, the effective means for preparing activated carbon are lacked to rough Chinese hawthorn seed charcoal, raw material can only be used as
It is outer at a low price to be sold to activated carbon factory, have a strong impact on the high value added utilization of charcoal.
(2) this technique is anti-with caused not condensable combustible gas and activation in production process during product is produced
Should the combustible gas such as gas be heating raw material, make use of the calorific value of pyrolysis gas to the utmost, effectively improve the thermal efficiency of system, drop
The low consumption in high-grade electric energy source, has obvious energy-saving effect.For original whole system, by Chinese hawthorn seed pyrolytic process
In caused pyrolysis gas directly empty or burn up, lack the consideration to thermal balance and afterheat utilizing system, not only cause resource
With the significant wastage of the energy, and certain pollution is also generated to environment, there are obvious energy-saving and emission-reduction potentiality.
(3) in this technological process, raw material can be made full use of, is disposably produced a variety of suitable for medical and health, food
Processing and the product in each field of environmental protection.It is different due to fumigating used time production cycle of gasification burner and activation furnace in process of production,
Can arrange in pairs or groups activation furnace multiple stifling gasification burners, also can in a production life cycle same stifling gasification burner come out of the stove it is more
Secondary rough Chinese hawthorn seed charcoal, thus can be by controlling the heating-up temperature acquisition of different stifling gasification burners is a variety of to evaporate oily product, example
Cut of the temperature in 80 DEG C -108 DEG C is such as controlled to do the raw material of food additives, the cut in 109 DEG C -169 DEG C can
With the raw material of the light industrial goods such as perfume (or spice) processed, medicinal raw material can be produced more than 170 DEG C.
(4) material heating charing, the activation in this technique are integral, and traditional method charcoal processing and activation process are point
Open, intermediate demand manually shifts, and labor intensity is big, and treatment effeciency is low, and can make rough Chinese hawthorn seed charcoal in transportation
Temperature reduces, and needs to reheat when activate in next step, causes the waste of the energy.This equipment does not have motion, structure
Simple with technique, continuous type commercial manufacturing equipment flow is complete, and continuity is strong, reliable, energy-conserving and environment-protective.
(5) the stifling gasification burner and activation furnace in this equipment are all conducted heat using external-heat, and furnace gas amount is small, and resistance is low,
Self-produced fuel gases calorific value is high.Combustion product gases do not contact directly as heat carrier with raw material, will not be mixed into charing caused by evaporate oil and
In water-gas caused by activation section, their calorific value is reduced, and gas circulation amount is little inside and outside stove, can reduce air resistance,
Dust-carrying capacity is reduced.
(6) response area of the activation cylinder in this activation furnace is big, can use less mistake with air good mixing
Measure air coefficient, the activated gas requirement being suitably lowered into.Activation body of heater is simple in construction, and consumable quantity is low, and heats passage
Burning velocity and efficiency are higher than grate furnace, and whole body of heater heat-transfer effect is good.
(7) activation process uses physical method, compares pollution of the chemical zinc chloride activation method to environment and the corruption to equipment
Erosion is lower.And chemical zinc chloride activation method easily corrodes because inboard wall of furnace body can contact with zinc chloride, produce plate face concavo-convex
Uneven, tilting is even burnt, and causes body of heater service life short, it is necessary to consider the processing of waste gas and waste water and equipment in production process
Anticorrosion Problems.
