Description
Technical field
The invention belongs to chemical fields, more particularly, to the purification of a kind of organic exhaust gas absorbent and environment-friendly type organic exhaust gas
Processing unit.
Background technology
The industries such as furniture, shoemaking, automobile, machinery, household electrical appliances, electromechanics, plastic products, hardware all must to product surface into
Row processing, it is most effective at present and most efficiently method is exactly to produce motley product by painted surface processing, it can be with
Greatly improve the aesthetic feeling of product.But the release that can volatilize in paint production, dilution, spraying process and during subsequent cure has
Machine exhaust emission.The comparison of ingredients of Organic Waste Gas Pollution object is complicated, mainly has low-molecular-weight organic compound and macromolecule organic
Compound, the water solubility and degradability of height organic compound differ greatly, especially as surface spraying, plastic processing, chemical industry,
The organic exhaust gas of the generations such as rubber, pharmacy, chemical fertilizer, printing, weaving, the solvent and diluent of surface spraying have benzene, toluene, diformazan
Benzene etc. is insoluble in the stronger water of polarity, and benzene,toluene,xylene is non-polar high polymer organic compound substance, also there is readily soluble water
The low poles low-molecular-weight organic compound such as methanol, ethyl alcohol, acetone, aliphatic ketone, formaldehyde, acetaldehyde.Most organic exhaust gas has carcinogenic, cause
Abnormal, mutagenic effect and genetoxic directly endanger the life and healths such as the mankind and other biological, such as benzene,toluene,xylene class pair
The nerve and hemopoietic system of human body cause great harm.
In China during high speed development, the environmental issue of getting worse receives the concern of social each side, has expedited the emergence of very much
The equipment for administering volatile organic matter (VOCs), such as common active carbon adsorption, plasma, ultraviolet light equipment.But

Saturation, short life, regeneration cost is high, ultimately forms dangerous waste；If equipment is out of service, due to losing negative pressure, adsorb
Release VOCs can be desorbed in activated carbon；Its operation is also influenced by humidity, dust and the temperature when working, and humidity is bigger, and dust is more,
Adsorption effect is poorer；Temperature is higher (China's summer temperature is higher for a long time), is more unfavorable for adsorbing.And non-thermal plasma trap, by
Steam, dust to exhaust gas influence also reduce treatment effeciency.In addition, if using the plasma of low energy, it is existing so-called
Plasma process mostly uses kitchen ventilator oil removing principle, is not suitable for administering substantially and contains phenyl ring class VOCs, if using big work(
There is also drawbacks for rate plasma technique, and equipment is expensive, such as plasma such as excitation generation electric arc, are inevitably generated smelly
The secondary pollutions such as the intermediate by-products of oxygen, nitrogen oxides and organic exhaust gas Partial digestion, more seriously, due to organic exhaust gas
Mostly inflammable, explosive compound, VOCs treatment engineering slightly flaw in design, when plasma operation
Arc electrode easily causes explosion accident, and the explosive incident of Tianjin has informed its security risk of everybody, this technology forbidden time
It is few.And can be influenced by dust when the application of ultraviolet photolysis technology, make radiation energy that can constantly weaken, and 185nm wavelength
Ultraviolet light will produce a large amount of ozone, cause secondary pollution, and existing treating method is substantially without moment reaction effect (with the country
Certain famous quartz burner supply enterprise is introduced, and in photocatalytic region, it is anti-such as without the sufficient time hydroxyl radical free radical to occur for organic exhaust gas
It answers, to organic exhaust gas degradation rate less than 10%), in addition, the titanic oxide material now used, if not being Detitanium-ore-type titanium dioxide
Titanium photocatalyst, it is basic without catalysis photodissociation effect.
Using each abatement equipment and combinations thereof mode as without quantitative analysis is carried out to processing, do not worked out specific aim solution
Scheme can not effectively administer Organic Waste Gas Pollution.Exhaust gas for different emission sources be also it is multifarious, VOCs treatment
Monotechnics have been difficult to make the discharge of organic exhaust gas to reach increasingly strict environmental requirement, therefore, to realize the new shape of environmental protection
Gesture needs to seek to meet environmental requirement and the higher group technology of cost performance, pushes the innovation and development of VOCs treatment technology.
