Description
Technical field
The invention belongs to technical field of waste gas treatment, in particular it relates to a kind of concave convex rod adsorbent for organic exhaust gas
And preparation method.
Background technology
The conventional method of current exhaust-gas treatment has combustion method, absorption process, bioanalysis, photocatalytic method, low-temperature plasma method, suction
Attached method etc..
（1）Combustion method
The temperature and assist medium difference of the main with good grounds burning of combustion method are divided into two kinds of direct combustion method and Production by Catalytic Combustion Process again.
Production by Catalytic Combustion Process is more suited to high concentration, the purification of small air quantity waste gas, when handling the waste gas of low concentration, due to 300- to be maintained
400 DEG C of catalysis ignition temperature, need to improve the combustion heat value of waste gas by means of concentration technologies such as charcoal absorptions, but in waste gas
Aqueous vapor, greasy dirt and particulate matter easily cause that charcoal absorption capacity declines and catalyst poisoning is the problems such as inactivate so that this method
Popularization and using being restricted to a certain extent.Direct combustion method is to add auxiliary fuel to send into burning together with waste gas
Stove burns, and direct burning process is ripe, controls contaminant removal efficiency under certain temperature conditionss high, burns thorough, but make
Problems with can be typically produced during：If easily producing two evils when 1. burning chloride, bromo organic matter and aromatic hydrocarbon substance
English class strong carcinogen, especially starts in incinerator and is more also easy to produce in closing process, to avoid dioxin-like chemical from producing, palpus
Ignition temperature is improved more than 1200 DEG C, not only running expense is high if keeping such high ignition temperature, and to incinerator
It is required that also greatly improving.2. hydrogen-chloride etching problem, especially at high operating temperatures, chlorine can be produced by burning when containing chlorinatedorganic
The corrosive nature for changing hydrogen is greatly enhanced, and is not only existed to pipeline and is corroded, can more seriously cause the corrosion of incinerator.3. burn
In the presence of the potential danger of blast during burning, especially effumability fuel gas is possible to if reaching that its explosion limit meets naked light
Set off an explosion.If in addition, in the case of containing halogen, nitrogen and element sulphur in waste gas, easily being produced using combustion method secondary
Polluter dioxin, oxynitrides and oxygen sulfur compound.
（2）Absorption process
Using the physics and chemical property of polluter, the method for waste gas absorb removal using water or chemical absorbing liquid.
This method removal efficiency in the case of design operation is rational is very high, and running management is convenient, but to equipment and operational management requirement
It is high, and can only be dissolved in absorbing liquid or be able to can be just efficiently removed with the pollutant of absorbing liquid reaction.
（3）Bioanalysis
Bioanalysis is a kind of more handling process of Recent study, and this method most prominent advantage is that processing cost is cheap, base
This non-secondary pollution.Although bioanalysis effect in purifying low-concentration organic pollution substantially, has the advantages that energy consumption is low, deposited
Vapour lock is big, degradation rate is slow, equipment volume is huge, the influence of vulnerable to pollution thing concentration and temperature, and the method is only applicable to
, also there is certain difficulty to the processing of hydrophobicity and recalcitrant substance in the processing of hydrophily and easily biological-degradable material.
（4）Photocatalytic method
Photosensitive semiconductor catalysis oxidation or nano-metal-oxide photocatalysis are also study hotspot in recent years, but the drop of the technology
Solution efficiency is controlled by polluter and catalyst surface interface diffusion rate, and catalyst is expensive, be easy to poisoning mistake
Effect, current photocatalysis technology is difficult to heavy industrialization application, is confined to experimental study and small air quantity application stage more.
（5）Low-temperature plasma method
Low-temperature plasma is the mistake that gas is ionized that internal and external electrode carries out passing through between gap discharge, gap in a high voltage state
Journey.Due to the higher 38000v of discharge voltage, electronics is producing substantial amounts of nitrogen oxides with the nitrogen collision in air, causes secondary
Pollution.
（6）Absorption method
This method is when polluter passes through equipped with adsorbent（Such as activated carbon）Adsorption tower when, using the adsorbent to pollution
The strong absorption affinity of thing, so as to reach the purpose of purification waste gas.This method equipment is simple, and relatively low, removal effect is required to pollutant
It is good, it is used for purifying the final stage processing of technique.But it is frequent that this method has the disadvantage that, adsorbent low to high-concentration waste gas treatment effeciency is needed
Change or regenerate.
Attapulgite has the advantages that cheap raw material, aboundresources and specific surface area are big as a kind of natural material, concavo-convex
Rod soil have special fibre structure and crystal structure, with many special materializations and processing performance, have " general-purpose it
The good reputation of soil ".Because attapulgite has larger specific surface area, stronger suction-operated is made it have, at a fairly low dense
Highly viscous suspension can be formed under degree, can be used as dytory, suspending agent, binding agent etc..
Attapulgite refers to a kind of clay mineral by key component of attapulgite.Attapulgite is hydrated for a kind of crystalloid
Alumina magnesia silicate, with unique layer chain structure feature, exists in crystal lattice, side crystal containing not in its structure
Quantitative Na+、Ca2+、Fe3+、Al3+, crystal is in needle-like, threadiness or fiber collection shape.With between chain structure and stratiform knot
Intermediate structure between structure, low intensity when not being crosslinked, easily breaks, and without elasticity, absorption and caking property are low.
The method of modifying of current solid material mainly carries out surface modification by surfactant to it, makes its surface electricity
Property changes, so that change its absorption property, but DeGrain.
Crosslinking agent is used primarily in macromolecular material, and the molecular structure of macromolecular material is not handed over as the line of a rule length
Low intensity during connection, easily breaks, and without elasticity, the effect of crosslinking agent is exactly to produce chemical bond between the molecule of line style, makes line
Type molecule is connected with each other, and forms network structure, improves intensity and elasticity, and the present invention attempts crosslinking agent being applied to concave convex rod
In the modification of soil, as a result there is significant effect to improving concave convex rod suction-operated.
The content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of concave convex rod adsorbent for organic exhaust gas
And preparation method, during it is an object of the invention to handle high-concentration waste gas for existing absorption method, adsorbent is made using activated carbon
The low deficiency of absorption efficiency, by the way that concave convex rod is modified, is prepared into adsorbent, reaches the effect of efficient process high-concentration waste gas
Really, medicinal herb componentses are added in addition, effectively remove removing exhaust gas peculiar smell.
A kind of concave convex rod adsorbent for organic exhaust gas is provided according to an aspect of the present invention, it is described to be used for organic waste
The concave convex rod adsorbent of gas includes the component of following parts by weight：Attapulgite modified 60-85 parts, Chinese herbal medicine mixed powder 15-25
