Abstract
A kind of method of administering volatile organic contaminant, it is characterized in that first by water-screen cabinet, the resinous principle of more than 95% in waste gas and dust-filtering being got off, then deliver in liquid absorption tower, be discharged into after reaching discharging standards after testing in air, waste gas imports oxidation Decomposition tower again, organic pollution remaining in waste gas is carried out oxidation Decomposition, removes the gas after the organic pollution in waste gas and be just discharged in air.Compared with the prior art the present invention, has the volatile organic contaminant (VOCs) can effectively removed in air, makes the advantage that the gas being discharged into air is up to state standards.
Description
Technical field:
The present invention relates to a kind of method of intelligence waste gas.
Background technology:
Volatile organic contaminant (VOCs) is the important air pollutants of a class, and under typically referring to boiling point 50 ~ 260 DEG C, room temperature, saturated vapour pressure is more than the organic compound of 133.3Pa, comprises hydro carbons, halogenated hydrocarbons, aromatic hydrocarbon, polycyclic aromatic hydrocarbons (PAH) etc.
Containing multiple VOCs in the process tail gas that industrial discharge is discharged as chemical plant, the flue gas of castoff burning, containing imperfect combustion hydrocarbons in the tail gas of vehicular emission.Interior decoration, finishing material are as also discharged the multiple volatile organic matters such as toluene, benzene, dimethylbenzene, formaldehyde under the normal temperature such as paint and solvent, timber preservative, coating, glued board
VOCs is the polluter of harmful health, the NO in it and air
2reaction generates O
3photochemical fog can be formed, and be dispersed in air along with peculiar smell, stench, spread effect is had to the eye of people, nose and respiratory tract, produce adverse effect to the internal organ such as the heart, lung, liver and nervous system, some is then the allergen affecting some organ of human body and body, even causes acute and slow poisoning, can carcinogenic, mutagenesis, can crop production reduction be caused simultaneously.Therefore, VOCs process is more and more subject to the attention of various countries, and many developed countries have all promulgated that corresponding decree is to limit the discharge of VOCs, have become a focus in Air Pollution Control.
Factory coating has solvent-home and water-iome paint at present, use all is in various degree containing the organic solvent of VOCs, solvent based coating organic solvent used mainly contains toluene, dimethylbenzene, benzene, acetate, low-carbon alcohols, low-carbon (LC) ketone etc., containing glycol ether and ester class thereof in water paint, propylene glycol etc., solvent based coating VOCs content 30 ~ 60%, water paint VOCs content 10 ~ 20%, in use all have the aerosol form of the VOCs of variable concentrations to discharge, thus aggravation PM2.5 is to the pollution of air.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of volatile organic contaminant (VOCs) can effectively removed in air, the method for the improvement volatile organic contaminant that the gas being discharged into air is up to state standards.
The present invention realizes like this, first by water-screen cabinet, the resinous principle of more than 95% in waste gas and dust-filtering are got off, then deliver in liquid absorption tower, polarity contained in waste gas and nonpolar organic principle is absorbed by spraying into vaporific absorbing liquid in gas, afterwards, be discharged into after reaching discharging standards after testing in air, if also do not reach discharging standards or to reach more than national standard high standard discharge, then will waste gas up to standard not also be had to import oxidation Decomposition tower, by spraying into vaporific oxidation liquid in gas, organic pollution (VOCs) remaining in waste gas is carried out oxidation Decomposition, remove the gas after the organic pollution in waste gas to be just discharged in air, here, absorbing liquid is the good fatty acid methyl ester of biodegradation or fatty-acid ethyl ester or both mixtures, oxidation solution is chlorine dioxide (ClO
2) aqueous solution.
The present invention adopts cascade to filter, dissolves the multi task process means such as absorption, oxidation Decomposition, constantly waste gas is processed, and, during process, by the mode of effective means as spraying, process medium is contacted fully with waste gas, ensure that validity and the completeness of the organic pollution (VOCs) administered in waste gas, make the gas after process reach the discharge standard of country.
Here, the absorbing liquid after liquid absorption tower uses is recycled by decompression distillation cutting absorbing liquid and VOCs, VOCs, and regenerable absorbent liquid then by pumped back liquid absorption tower, like this, would not produce secondary pollution.

Compared with the prior art the present invention, has the volatile organic contaminant (VOCs) can effectively removed in air, makes the advantage that the gas being discharged into air is up to state standards.
Accompanying drawing illustrates:
Fig. 1 is process chart of the present invention.
Detailed description of the invention:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the present invention realizes like this, first by water-screen cabinet, the resinous principle of more than 95% in waste gas and dust-filtering are got off, then waste gas is delivered in liquid absorption tower, in gas, spray into vaporific absorbing liquid by the absorbing liquid circulatory system and absorb polarity contained in waste gas and nonpolar organic principle, afterwards, be discharged into after reaching discharging standards after testing in air, if also do not reach discharging standards or to reach more than national standard high standard discharge, then waste gas is imported oxidation Decomposition tower, in gas, vaporific oxidation liquid is sprayed into by the oxidation liquid circulatory system, organic pollution (VOCs) remaining in waste gas is carried out oxidation Decomposition, remove the gas after the organic pollution in waste gas to be just discharged in air, here, absorbing liquid is the good fatty acid methyl ester of biodegradation or fatty-acid ethyl ester or both mixtures, oxidation solution is chlorine dioxide (ClO
2) aqueous solution.The absorbing liquid circulatory system comprises absorbing liquid circulating tank, pump, and the absorbing liquid in absorbing liquid circulating tank is by being pumped into in the vaporific waste gas sprayed in liquid absorption tower in liquid absorption tower, and the absorbing liquid collected by liquid absorption tower then leads back in absorbing liquid circulating tank; The oxidation solution circulatory system comprises inhales oxidation solution circulating tank, pump, oxidation solution in oxidation solution circulating tank is by being pumped into in the vaporific waste gas sprayed in oxidation Decomposition tower in oxidation Decomposition tower, and the oxidation solution collected by oxidation Decomposition tower then leads back in oxidation solution circulating tank.
Here, the absorbing liquid that liquid absorption tower uses is recycled by decompression distillation cutting absorbing liquid and VOCs, VOCs, and the absorbing liquid of regeneration is then by the absorbing liquid circulating tank in the pumped back absorbing liquid circulatory system.
