Background
Volatile Organic Compounds (VOCs) are a generic term for any Organic compound having a boiling point below 250 ℃ at atmospheric pressure, or any Organic compound having a saturated vapor pressure exceeding 133.32Pa at room temperature (25 ℃) and being emitted as gaseous molecules into the air. VOCs not only have strong toxicity, but also are important precursors and participators which influence the atmospheric composite pollution in China. Therefore, the control of the VOCs has important significance for improving the quality of the atmospheric environment in China.
The prior art processes for treating exhaust gas containing volatile organic compounds include: active adsorption method, induced air high-altitude discharge method, combustion processing method, absorption degassing method, condensation collection method and biological processing method.
In the organic waste gas treatment process, an active adsorption method is one of the methods with good treatment effect and wider application range, and the adsorbents comprise active carbon, diatomite, zeolite and the like, wherein the active carbon adsorption is most applied. Through adsorption system, not only can make VOCs concentration greatly reduced, realize that waste gas discharge to reach standard, adsorb the back moreover through the stripping desorption, the collection can be used for production again, but has the absorption incomplete, remain shortcoming such as more.

However, the high-altitude discharge is only pollution transfer, the pollution problem is not really solved, and the power of the induced draft fan and the installation height of the air inlet directly influence the induced draft effect.

As the VOCs are generally dissolved in organic solvents such as diesel oil or 200 # gasoline, the VOCs can be absorbed by the diesel oil or 200 # gasoline, and the absorbed solvents can be used for fuel or diluents. The method is convenient to operate and low in cost, but volatile gas residues generally exist after absorption treatment, and the organic solvent is volatile, so that VOCs cannot be reduced to zero, and the absorptivity is lower when the organic solvent meets high temperature.
The high-temperature organic gas in the reaction kettle can be collected by condensation, and is firstly directly condensed and then spirally condensed, so that the method has the advantages of obvious degassing effect, easy operation and low operation cost, but has poor effect on low-boiling-point gas.
The biological treatment method is to absorb VOCs by water or weak alkali liquor, wherein the substances such as alcohols, aldehydes and the like contained in the VOCs are easy to dissolve in water, and the absorbed waste water is biodegraded to ensure that the waste water reaches the standard and is discharged. The biological treatment method is that the greening area is increased in a plant area, and the air is purified by absorbing and converting pollutants in the atmosphere by using green plants, and the method is only suitable for large-environment low-concentration pollution.
