Description
Technical field
The utility model relates to the reactor that a kind of VOCs administers, and relates in particular to the reactor of a kind of embedded plasma adsoption catalysis improvement VOCs.
Background technology
Volatile organic matter (VOCs) is the atmosphere pollution that the second largest class after dust has a large capacity and a wide range, and they not only can cause the atmosphere polluting problems such as ozone cavity, photochemical fog, and are mostly noxious material, and health is produced to significant damage.VOCs in waste gas is not only of a great variety, and concentration is mostly at hundreds of ppm, and intractability is very big.Traditional VOCs control method is to utilize active carbon to adsorb it, but absorption after active carbon often directly abandon landfill, be easy to cause secondary pollution.So the research of the control of VOCs in recent years progressively turns to and VOCs can be converted into innocuous substance (CO
2and H
2o etc.) method.Low temperature plasma VOCs control technology utilizes gas discharge under highfield to produce to have the materials such as the high energy electron, ion, free radical of extensive chemical activity very, these active particles are strengthening oxidability, are promoting the aspect such as molecular dissociation and acceleration chemical reaction all to have very high efficiency, can carry out deep oxidation to the VOCs of low concentration in waste gas, generate harmless CO
2and H
2o, thereby become gradually the focus that domestic and international VOCs control technology is researched and developed.Dielectric barrier discharge is to have at least an electrode surface to be insulated dielectric to cover, or inserts a kind of discharge type of insulation dielectric at discharge space.Micro discharge is the core of dielectric barrier discharge, and micro discharge process not only plays energy storage effect, and freely increasing of Limited Current density, makes discharge stability and produce the extremely short pulse of time delay, can also prevent local spark or arc discharge.And dielectric barrier discharge can and the technology combination such as absorption, catalysis, make plasma oxidation, chemisorbed and catalysis performance synergy, the degraded VOCs of effective, harmless, thereby become gradually the optimal path that VOCs degrades.
Dielectric impedance micro discharge can produce electronics, ion and the free radical in a large number with extensive chemical activity, and organic pollution is oxidized to CO
2and H
2the innocuous substances such as O.Although but research shows that simple dielectric impedance micro discharge has higher removal efficiency to benzene, toluene, trichloro-ethylene etc., exists the problems such as capacity usage ratio is low, carbonation rate is not high.The people such as Magureanu (M.Magureanu, N.B.Mandache, et al.Applied Catalysis B-Environmental, 2007, when 74:270-277) working medium barrier discharge is processed trichloro-ethylene, find, although obtained 90% removal efficiency, energy density has reached 500J/l, in addition CO in accessory substance
2selection rate also only have 25%, in processing procedure, generated more CO.Recently, in order to overcome the shortcoming of simple dielectric impedance micro discharge, combining medium barrier discharge and chemical catalysis are processed organic pollution and are progressively grown up, removal efficiency, capacity usage ratio and CO
2selection rate all increase (T Hammer, T.Kappes, et al.Catalysis Today, 2004,89:5-14; R.B.Sun, Z.G.Xi, et al.Atmospheric Environment, 2007,41:6853-6859).The people such as Delagrange (et al.Applied Catalysis B.2006:68:92-98 for S.Delagrange, L.Pinard) find that dielectric barrier discharge is in conjunction with MnO

2o
3when catalyst can make toluene conversion from independent electric discharge 36% brought up to 88%, CO
2the ratio of/CO brings up to 1.3, MnO simultaneously from 0.75
2can effectively suppress O
3the generation of this accessory substance.In addition, research shows that dielectric barrier discharge and chemical catalysis are in conjunction with producing cooperative effect, and dielectric barrier discharge can promote the generation of catalyst surface active material, and adding of catalyst can be strengthened ionization, in catalyst micropore, produce gas discharge, thereby promote the generation of active material.The catalysis of dielectric barrier discharge combinatorial chemistry has improved the removal efficiency of organic pollution to a certain extent, has reduced energy consumption, has suppressed the generation of harmful side product.But due to generally lower (hundreds of ppm) of the concentration of VOCs in waste gas, and existence form is various, causes energy consumption higher, CO
2selection rate is lower.For this reason, how to improve the degradation efficiency of VOCs, reduce energy consumption, effectively control the generation of harmful degradation by-products, will become plasma-catalytic in conjunction with the key point of processing VOCs technology.And design improvement aspect reactor will be one of important channel solving this key issue.
The reactor of plasma body cooperative chemical catalyst is generally divided into two-part and one-part form.After in two section reactor, catalyst is generally placed in discharging plasma reactor, the catalytic reaction segmentation of plasma chemical reaction and induction is carried out.For two section reactor, short life active specy is generally difficult to reach the catalyst section in region of discharge downstream, is mainly by the N in short life active particle and atmosphere

2react Deng at catalyst surface and VOCs molecule, can not embody the synergy of nonthermal plasma and catalyst completely.And one-part form catalyst reactor and plasma discharge combine, the short life active specy of discharge generation as O (
1d), O (
3p), OH-can arrive rapidly catalyst surface, for the very important effect of chemical characteristic that improves catalyst surface.Two section reactor advantage in the application that removes VOCs is less, and Just because of this, current plasma catalytic reactor is mainly one-part form reactor.
But one-part form plasma catalytic reactor is owing to adsorption catalyst will being filled in the gap of plasma reactor, but the gap of plasma reactor is often at 100～300mm, the adsorption catalyst of filling is limited, and the time of staying of gas is shorter, and adsoption catalysis effect is poor.And traditional two-period form plasma catalytic reactor, due to plasma and adsorption catalyst are divided into two sections of layouts, the active particle producing in plasma process is because the life-span is extremely short, cannot arrive adsoption catalysis section, element is can not efficiently bring into play the cooperative effect between plasma and adsoption catalysis.
