High Material Industrial Drying Equipment For Chicken Manure
Material Description:
Light material means the powder or small particle material with the
density of about 0.4-0.6t/m³, such as
sawdust, bamboo shavings, rice husk, xylose, wood shavings, wood
blocks, etc.
Light material is generally with high water content, such as,
commonly the saturated water content of
the sawdust is 45-50%, and some of them can reach 60%; The light
material is relatively loose, the use
of air transport will not plug the pipeline.
System Introduction
In recent years, with the increasing of environmental resources,
the comprehensive utilization of
biomass energy has become more and more important to us. Due to the
high moisture content of the
sawdust, broken wood, which leads the incomplete combustion,
resulting in that the spark burns the
dust bag at the back of the drying plant, which not only causes the
excessive emissions, but also it’s
with high cost to change the dust bag. In the process of producing
wood products and biomass fuels
with high burning combustion value, wood chips and broken dregs are
required to do the drying process.
Process Flow:
After being fed into the hopper, under the function of gravity the
raw material will fall onto the belt
conveyor laid under the bottom of the hopper, and then which will
be conveyed onto the screening
machine, the massive, strip and other irregular material will be
separated out after screening, and
uniform particles will be conveyed to the feeding end of the dryer
(The single cylinder or three cylinder
dryer will be chosen as per the service condition) by the belt
conveyor under the screening machine.
The feeding end of the dryer is connected with heat source and the
discharging end is linked with pulse
air pipes. The fire wall will be setted up in the hot blast stove
in order to guarantee the safety of the
drying process, to eliminate the phenomenon of material burning in
the dryer, and the heat passing
through pipe will be installed between the hot blast stove and the
dryer as the section of heat buffer. The
material will brought into the diameter-transformed pulse pipe
after being dried and the dehydration for
the first time inside of the dryer, which will be in a suspended
boiling form at the large diameter of the
pulse pipe, and then it will be quickly dried after contacting with
the exhausted heat wind from dryer.
And the material will be driven out of the pulse pipe by strong
winds and moved into the first stage
cyclone collector when its water content reaches the design
requirement, and 80% of dried material will
be collected, and then get into the second stage cyclone collector
after passing through the induced
draft fan to collect the left material. The second stage cyclone
collector can be replaced by the bag type
dust collector.
System Advantages:
Advanced internal structure strengths heat exchange, that is to
say, increasing thermal efficiency. The
light material industrial drying equipment has advanced design,
which let the material has the full
contact in the dryer, the full surface area of the particles is the
effective drying area, and it has Intensive
drying strength. With the pulse air flow dryer, drying time is only
half of the regular dryer, the efficiency
of the drying machine is greatly increased. The light material
industrial drying equipment has advanced
structure, with small mall covered area, easy to construct and to
do maintenance. The thermal
efficiency can reach 90% when it dries unbound water. The final
moisture is stable (10%-13%) after the
regular light material being dried, and the dried material doesn’t
contain impurities.
