Operation principle and feature：
The present invention uses a kind of modified active carbon adsorbent, using the quick adsorption ability of modified active carbon adsorbent to having
Organic matter in machine exhaust gas is fast and effectively adsorbed, by Adsorption of Organic in adsorbent surface.Then pass through activity
(active oxygen includes ozone, oxygen, hydrogen peroxide and hydroxyl radical free radical (O to the activated oxidized water that Oxygen Generator produces3,O,H2O2, OH)) it is right
Modified active carbon adsorbent carries out cleaning showers, and the organic pollution of modified activated carbon adsorbent surface is carried out to the oxidation of depth
Processing, makes organic pollution be rapidly and thoroughly degraded to the material of environmental sound.Meanwhile it is adsorbed in modified active carbon adsorption
The organic pollution on agent surface is disposed of, and modified active carbon adsorbent is in undersaturated condition all the time, is reduced regenerated
Demand.Backwash need not be carried out to adsorbent, when operation can combine active oxygen, soon in the processing unit and treatment process operational process
Speed effectively aoxidizes the organic pollution in exhaust gas, and adaptable, processing speed is fast, and floor space reduces significantly.
Property according to exhaust gas can use specific medicament with processing target, traditional active carbon, carries out surfaction, is made
The modified active carbon adsorbent of " suiting the remedy to the case ", enables modified active carbon adsorbent " selective " to go having in removing exhaust gas
Machine matter.Modified, the original surface texture of activated carbon and hole are constant, thus modified active carbon adsorbent still have except color,
The inherent characteristic of deodorization isoreactivity carbon.
Activated oxidized water mainly includes ozone, oxygen, hydrogen peroxide and hydroxyl radical free radical (O3,O,H2O2, OH) and as main oxygen
Agent.It is known that the oxidizing potential of oxidant is higher, its oxidation susceptibility is stronger.The oxygen of some oxidants is listed in table 1
Change current potential, order from high to low arranges, the higher oxidant of oxidizing potential oxygen, and decomposing organic matter ability is just stronger.Active oxygen
Ozone, oxygen, hydrogen peroxide and hydroxyl radical free radical (OH) are included in water, by table 1 as it can be seen that hydroxyl radical free radical (OH) is to compare ozone
More powerful oxidant, and all reactions with (OH) degradable organic pollutant, just referred to as advanced oxidation processes.So
To in the oxidizing process of the organic matter in exhaust gas, under ozone, oxygen, hydrogen peroxide and hydroxyl radical free radical (OH) collective effect, to useless
The detergent power of organic matter in gas is more preferable than traditional other modes effect.
The oxidizing potential of 1 some oxidants of table
In addition, table 2 compares the reaction rate (unit of some organic matters of ozone Yu hydroxyl radical free radical (OH) oxygenolysis：
M-1·sec-1, M is molar concentration)：
2 O of table3The reaction rate of some organic pollutions is decomposed with OH
So the present invention is using a variety of in the activated oxidized water containing ozone, oxygen, hydrogen peroxide and hydroxyl radical free radical (OH)
Oxidant can be very quick for the organic matter of the Various Complex in gas, effective oxidation removal.It is opposite with other exhaust gas
Processing scheme, has incomparable advantage.
The processing unit and treatment process that the physical adsorption techniques that the present invention uses are combined with high-level oxidation technology, on the one hand
