Description
Technical field
The present invention relates to a kind of manufacturing methods of activated carbon.
Background technology
Recently as expanding economy, manufacturing a large amount of new, plus the inadequate of environmental protection investments dynamics, result in
The discharge of a large amount of industrial organic exhaust gas so that atmosphere quality declines, and seriously endangers to health, is made to national economy
At massive losses, therefore, it is necessary to increase the processing to organic exhaust gas.
Activated carbon is a kind of very excellent adsorbent, it be using coconut husk, bamboo charcoal, various shells and fat coal etc. as
Raw material, raw material is crushed by physics and chemical method, is sieved, activation of catalyst, rinsing, drying and screening etc. it is a series of
Process fabricates.
It has the double grading of physical absorption and chemisorption, can selectively adsorb various in gas phase, liquid phase
Substance, to reach the purpose of decolorizing and refining, disinfecting, deodorizing and decontamination purify.The difference produced at present with Physical and chemical method
The physical and chemical properties of the activated carbon of material are not quite similar, and different raw materials has different empty diameters, wherein using coconut husk as raw material
Activated carbon aperture it is minimum, the aperture of wood activated charcoal is generally large, and the aperture of coaly activated carbon falls between.At present
Lack in activated carbon application technology and be directed to different absorption objects, selects the application technology of the activated carbon of respective material.Activated carbon
It is all used for the decoloration of liquid phase adsorption in industrial circle, refines, purification, and in terms of Gas Phase Adsorption, powdery and granular activated carbon are just not
The intimate contact of poisonous and harmful substance in energy and air, to be greatly lowered adsorption effect.
The windage of particle charcoal is excessive, and adsorption rate silk ribbon attached to an official seal or a medal is slow, and desorption time is long, and desorption effect is bad, leverages environmental protection
The use of equipment increases the operating cost of environmental protection equipment.The ability of existing honeycomb briquet absorption benzene only has 30% or so, can not
Meet the use of ultra-long time work.
