Â
Coconut husk, apricot
kernel shell, walnut shell, hawthorn kernel
shell, peach kernel
shell, coal, palm kernel shell and charcoal are
common raw materials of
activated charcoal products available on the
market. Regional
resource superiority is dominant in material selection.
The plant is integrated
with an automatic control system. Main structure
of the activation
furnace consists of a material bin, an elevator, a
feeder,
a furnace stack,
refractories, a rotator, a temperature detector, an
activator, a cooler, a
settling chamber, a boiler, a fan, a deduster, and an
automatic PLC
system.
Â
Raw materials are
carbonized and screened to eliminate particles
under 2mm. Moisture
content shall be controlled at a level below *5%.
Then, materials are
filled into the elevator bin, and conveyed to the feeder
on top. From the feeder
bin, materials are fed into the furnace evenly by a
variable-frequency
feeder, and heated by an ignitor. Temperature inside
the furnace shall be
above **0°C before feeding. A calculated
amount
of oxygen and vapor is
delivered into the furnace through the fan for
activation. 4 tons of
vapor are required for one ton of finished activated
carbon products, and
penetrating vapor shall be used instead of spreading
vapor for restraining
ignition loss and improving efficiency. Materials are
conveyed into the
pre-heating section following rotating movement of
the furnace, and then
into the activation section after their temperature
reaches
**0°C.
Temperature of the material will climb dramatically to
*******0°C
after contact with
vapor. Duration of the contact between
material and vapor is
known as Activation Time, which is variable within
the range of ****0
minutes, given the specific temperature and oxygen
amount. To meet the
duration required, materials in the furnace shall
be moved forward at a
rate of 6m/h. Temperature of materials shall be
******0°C
in the discharge tube
of cooling section, and around **0°C as
they leave the tube for
a water-cooling device separated with the furnace,
where the activated
materials shall be cooled to a room temperature
between ****0°C
after approximately 3
minutes of anaerobic cooling
before they slide into
prepared jumbo bags (0.5 ton of capacity each)
out of gravity, or
convey to the next bin for grinding via the pneumatic
Â
conveyor. Filled jumbo
bags may be moved by manual forklifts. The
settling chamber in the
end of the furnace is designed for 4 purposes,
which are preheating
the waste heat boiler, dust settling, keeping vapor
infusion to avoid
frozen pipelines in cold regions, and combusting
incomplete combusted
fume to reduce black smoke and efficiently use
energy generated by
fume combustion. The waste heat boiler connected
to the settling chamber
is designed for generating vapor for activating
material by
high-temperature (around **0°C) end gas. The induced
draft
fan connected to the
boiler is designed for pumping the high-temperature
end gas into the waste
heat boiler, and then into the pouch- style pulse
dust collector for
subsequent end-gas treatment, such as sprinkling, to
meet emission standard.
Output of the plant varies with specific material
type and quality
requirements. Desulfurization and denitrification
devices
are required for coal
carbon production. See the table below for outputs.
Â
The entire process is
controlled by a PLC system which offers
much lower labor
intensity, controllable quality, safety, much less
manual
work, comparing to
traditional operation mode. Moreover, the plant is
capable of prolonged
continuous operation without blowing out, thanks
for a maintenance ratio
significantly lower than that of products of other
manufacturers'.
