Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
The present embodiment proposes a kind of denitrating flue gas ozone reaction device, and it includes two reaction chambers：First reaction
Chamber, the second reaction chamber；And two ozone injection apparatus：First ozone injection apparatus 10, the second ozone injection apparatus 20, such as scheme
1st, shown in Fig. 2.First ozone injection apparatus 10 is used to spray ozone to the first reaction chamber, and the second ozone injection apparatus 20 is used for
Ozone is sprayed to the second reaction chamber.Wherein, the first reaction chamber, the planform of the second reaction chamber, size be not unique,
The arrangement mode of the two can also specifically be fabricated according to place, and such as linear or curve is arranged, in setting angle successively
Arrangement or suit arrangement.Particularly, the present embodiment is provided with first passed through for outside flue gas on the first reaction chamber and entered
Gas port 31, the second air inlet connected with the first reaction chamber is provided with the second reaction chamber（It is used to be used as the first reaction chamber
The exhaust outlet of interior flue gas）And the gas outlet connected with outside scrubbing tower.
After the flue gas for purifying outside need is delivered in the first reaction chamber by the first air inlet 31, the injection of the first ozone
By spraying ozone into the first reaction chamber stair oxidation reaction occurs for device 10, following several feelings in stair oxidation reaction
Condition：
NO+O3=NO2+O2 (a)
NO2+O3=NO3+O2 (b)
NO2+NO=NO3+O2 (c)
NO2+NO3=N2O5 (d)
The high-speed jet of ozone formation and the limitation of the first reaction cavity space cause ozone itself and cigarette in course of injection

Mouthful size and the first ozone injection apparatus 10 ozone injection flow come control flue gas flow rate in the first reaction chamber and
In the reaction time, to ensure that ozone amount is appropriate in the first reaction chamber, and utilize ozone oxidation NO reaction generations NO2Required activation energy
Relatively low characteristic, generation key reaction is NO+O3=NO2+O2（a）Stair oxidation reaction, not only ozone be utilized effectively and
And fully consumed NO unstable in flue gas, a large amount of metastable NO of generation2, prevent the excessive N generated2O5Passing through
Decomposed before the gas outlet of second reaction chamber, so as to cause the problem of denitration effect is poor.
Second ozone injection apparatus 20 to the second reaction chamber when spraying ozone, and the high-speed jet of formation causes the second reaction
Intracavitary negative pressure, thus can be constantly by reacted flue gas in the first reaction chamber（Contain a large amount of NO2）, adhesion and sweep along paramount
In rapid fire stream, volume inhale with blending result jet area is constantly expanded, flow velocity is constantly reduced, flow along Cheng Zengjia so that
Preferably the ozone newly sprayed and flue gas are sufficiently mixed, two grades of oxygen of flue gas and ozone are realized in the case where being sufficiently mixed
Change reaction, due to fully having consumed the NO in flue gas in the first reaction chamber, therefore, reacted in secondary oxidation reaction
There are following several situations：
NO2+O3=NO3+O2 (b)
NO2+NO3=N2O5 (d)
2NO2+O3=N2O5+O2 (e)
Due to generating substantial amounts of NO in the first reaction chamber2Its ozone sprayed with the second ozone injection apparatus 20 is sufficiently mixed,
So that the key reaction in secondary oxidation reaction is 2NO2+O3=N2O5+O2 (e) ozone, newly sprayed is not only consumed
A large amount of NO2, but also generate the N for largely easily reacting, easily being removed by spray with water2O5, the N specifically generated2O5Penetrating
