Description
Air
purification activated carbon uses the materials with higher carbon
as raw material such as coal，nut
shell, wood, bone, petroleum residue and etc. The product is
produced through professional activating treatment to form abundant
micropore, which makes the specific surface area and adsorption
capacity achieve certain requirements. The air purification
activated carbon production usually divides into two processes, one
is carbonization, the other is activation. Activated carbon
includes decolorization activated carbon, water purification
activated carbon, air purification activated carbon, heavy metal
recovery activated carbon and so on. Air purification activated
carbon has widely usages, and is the high quality adsorbing
material.
Air
purification activated carbon is one kind of activated carbon, and
specially used for purification of polluted air. The air
purification activated carbon must have the characteristics of good
hardness, high strength, micropore structure. The nut shell carbon,
coal carbon can be used as the raw materials of air purification.
The nut shell carbon has the best effect.
The process of
air purification activated carbon production
1. Carbonization
The nut shell
carbonization furnace is used to through pre-heat, then go into the
carbonized process with high temperature heating from **0 to **0,
and provide air combustion-support without any other fuel. Then the
process goes into cooling coil section. The carbonized exhaust
won’t pollute the air. The structure of the carbon is graphite
shape hexagonal microcrystalline.
2.
Activation
The activation
of air purification activated carbon uses air activation method.
Usually the activated carbon activation furnace uses the steam and
the activation process produced flue-gas as activator to finish the
activation process together. The activation needs the high
temperature from **0 to **0, about also needs *0 atmospheric
pressure.
Air
purification activated carbon adsorption effect
principle
Air
purification activated carbon is black and one kind of
microcrystalline carbon materials with advanced internal pore
structure, large specific surface area and strong air adsorption
ability. Air purification activated carbon material has a plenty of
invisible micropore, the specific surface area of micropore of 1g
activated carbon material unfold can achieve **0—***0 square meter,
and the specially usage activated carbon can achieve higher. It
means that the internal surface area of micropore of a rice
grain-size air purification activated carbon particle may
equivalent to a sitting room area. Because of the highly
development and just as human blood capillary pore structure, the
activated carbon owns excellent adsorption capacity.
