Description
Technical field
This utility model relates to a kind of electric field arrangement and method for gas purification, relates in particular to a kind of high energy electric field arrangement of Purge gas and the method for utilizing electric field high-energy discharge Purge gas.
Background technology
Gaseous contamination in the building is mainly produced by the following aspects:
Meetings such as workshop and laboratory produce and comprise multiple organic volatile harmful gass such as hydrogen sulfide, ammonia, aldehydes and benzene class;
Harmful smokes such as organic volatiles such as the nicotine in smoking place, tar and carbon monoxide;
The interior decoration meeting produces formaldehyde and benzene class organic volatile;
Office building, hotel, hospital, market, movie theatre, restaurant, gymnasium, indoor public place of entertainment etc. are because crowd massing, harmful organic volatile constantly produces, under the situation of central air-conditioning, the air dirt, pollutant, antibacterial and virus are invaded human body easily;
When automobile entered the tunnel, the speed of a motor vehicle was slower, during the wagon flow peak in the tunnel traffic not smooth, be in idling mode often and travel, cause gasoline, diesel combustion incomplete, produce high density pollution waste gas; Automobile exhaust gas contains the different chemical compounds of kind more than 150, in gas, endangers maximum to the people and is carbon monoxide, nitrogen oxide and Hydrocarbon, accounts for more than 80%～90% of whole harmful gass.
Air gas pollutant purification technology can be divided in the building:
(I) adsorbents adsorb gas pollutant, adsorbent can be saturated;
(II) catalyst is removed gas pollutant, catalyst meeting inactivation;
(III) existing low temperature plasma is removed pollutant, and technology exists that energy-flux density is low, energy level is not high, removes the inefficient defective of pollutant.
In recent years, the low temperature plasma technology of purifying air has been carried out a lot of researchs both at home and abroad, it has been expressed very big expectation (R McAdams Prospects for non-thermal atmospheric plasmas for pollution abatement.J.Phys.D:Appl.Phys.34 (2001) 2810-2821).But because of Energy Efficiency Ratio is not high, the energy of charged particle is lower, has limited its application.Low temperature plasma-catalyzing cooperation purification techniques is a new treatment technology, energy consumption is lower, aspect processing VOCs, nitrogen oxide, the motor-vehicle tail-gas vast potential for future development (Miessner H is being arranged all, Francke K, Rudolph R.Plasma-enhanced HC-SCR of NOx in the presence of excess oxygen[J] .Applied CatalysisB:Environmental, 2002,36:53-62; Huang Liwei, Lin Xinhai, Gu Qiaonong etc.: corona-absorption process is administered toluene waste gas experimentation [J]. ACTA Scientiae Circumstantiae, 2006,26 (1): 17～21), but experiment only be low-temperature plasma bulk electric field independently and independently catalyst put together, electric field reaction and catalytic reaction do not match, removal pollutant effect instability.Patent " nano titanium oxide plasma discharge catalytic hydroxyl radical free radical-ozonator " (the ZL. patent No. 03251304.6) is used for fields such as sewage treatment equipment, adopted concentric tube electrode field, load nano-titanium dioxide between electrode carries out strong oxidation processes to waste water.
In addition, adsorbent, catalyst being removed toxic gas such as carbon monoxide, nitrogen oxide, sulfur dioxide and Hydrocarbon both at home and abroad and carried out big quantity research, but be not DeGrain, is exactly the too high or very fast inefficacy of price.
