The R & D Department of the company has invented a new type of waste gas treatment device: volatile organic pollutant waste gas treatment device, which is characterized in that the device includes a gas collecting hood, a dry filtering and dedusting device, a plasma purification treatment device and an ozone oxidation treatment device. The gas collecting hood is arranged before the dry filtering and dedusting device, and a plasma purification place is arranged after the dry filtering and dedusting device After the plasma purification treatment device, the ozone oxidation treatment device is arranged.
With the wide application of organic chemical products in industrial production, more and more organic pollutants enter the atmosphere, mainly volatile organic compounds (VOCs) with low boiling point, that is, organic compounds with saturated vapor pressure greater than 71pa at room temperature or boiling point lower than 260 ℃ at atmospheric pressure. VOCs mainly come from petrochemical, pharmaceutical, printing, papermaking, bonding, coating decoration and other processes, The most common pollutant discharged in the production, storage and transportation of paint, shoemaking, spray painting, rubber and plastic products forming, photographic film and picture tube coating, surface anticorrosion, transportation, metal plating, textile and other industries. At the same time, the placement and use of various chemical reagents and drugs in the laboratories of universities, research institutes, inspection and testing institutions, as well as the volatilization of samples VOCs waste gas will be produced by the leakage and emptying of the intermediate products in the analysis process, including various hydrocarbons, halogenated hydrocarbons, alcohols, ketones, aldehydes, phenols, ethers, acids, amines, aromatics, lipids and other organic pollutants.
At present, the main means to control VOCs waste gas at home and abroad are as follows:
2. Absorption method;
3. Direct combustion
4. Catalytic combustion;
5. biological method
6. Method of recovering pollutants;
7. Adsorption catalytic combustion;
8. Photocatalysis, to some extent, has some problems, such as high equipment investment, high operation cost, small treatment gas volume, unstable work, large occupation space, low treatment efficiency, secondary pollution and so on.
Another purpose of the utility model is to provide a treatment equipment for waste gas of volatile organic pollutants, which has small investment, low operation cost and small volume. The technical problem to be solved by the utility model is that, in view of the above defects of the prior art, the utility model provides a treatment equipment for the waste gas of volatile organic pollutants, which can efficiently remove VOCs without secondary pollution, and the equipment can adapt to a variety of pollution environments, with strong adaptability and large treatment capacity.
