Art belongs to field of environmental improvement.
Background technology
It is with carbon content is higher and the relatively advanced substance in gap, such as coal, shell, timber, bone, petroleum residue in activated carbon
Deng for raw material, charing is first passed through, is handled using 800 to 1500 DEG C of high-temperature activations, forms flourishing micropore and mesoporous, makes it
Specific surface area and adsorption capacity reach certain requirement.The production of normal activated carbon is generally divided into two processes, and first：Charing,
Second：Activation.It is the attainable most effective sorbing material of current scientific level institute.
Air purification activated carbon selects good timber or cocoanut shell, passes through deep activation and unique aperture adjustment work
Skill makes activated carbon have abundant hole, and the size in hole is slightly larger than toxic gas, specific surface area>1300 m2/ g, for benzene, first
The toxic and harmful gas such as aldehyde, ammonia have high-effect adsorption capacity, can effectively remove the gaseous pollutant in room air and have
Evil odorant, and then achieve the purpose that reduce pollution, purification air.
When activated carbon adsorption saturation, that is, reach saturated extent of adsorption, need replacing new activated carbon, waste and old activated carbon will be lost
It abandons, a large amount of waste and old activated carbon will be generated in this way, not only polluted the environment, but also increase use cost, be unfavorable for society
It can develop.
At present, a large amount of research has all been done to the regeneration of activated carbon and its application both at home and abroad, it is proposed that a variety of regeneration technologies
Technology common are hot recycling method, bio-regeneration method, chemical solution method of reproduction etc..The absorption of the regenerated activated carbon of hot recycling method
Efficiency can decrease, and repeated regeneration can lose absorption property.Bio-regeneration method is only applicable to what absorption was easily decomposed by the microorganisms
The saturation charcoal of organic matter, and decomposition reaction must be thorough, i.e., and organic matter is finally broken down into CO2And H2Otherwise O has active
The possibility that charcoal adsorbs again.Chemical solution method of reproduction is relatively specific for those reversible adsorptions, such as to high concentration, low boiling point organic wastewater
Absorption；But the regeneration of this method is less thorough, and micropore easily blocks, and influences the recovery rate of absorption property, repeatedly absorption property after regeneration
It is substantially reduced.
