Preferably, being provided with booster fan between the activated carbon adsorption device and plasma purifier.
Compared with prior art, it is the advantages of the utility model with good effect：
1, the utility model passes through conventional carbon absorption and desulfurizing tower denitration desulfurization method and advanced plasma flue gas
The mode of purification and ozone, hydrogen peroxide oxidation process combination meets the needs of different denitration discharge standard bricks, makes coke oven flue gas denitration
Desulfurization degree is up to 98% or more.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, it should be apparent that, the accompanying drawings in the following description is some embodiments of the utility model,
For those of ordinary skill in the art, without any creative labor, it can also obtain according to these attached drawings
Obtain other attached drawings.
Fig. 1 is a kind of system construction drawing for coke oven flue gas denitration desulphurization system that embodiment 1 provides；
In above each figure, 1, activated carbon adsorption device；2, plasma purifier；3, mixer；4, hydrogen peroxide injection device；
5, ozone generator；6, booster fan；7, desulfurizing tower；8, demister；9, chimney.
Specific embodiment
It is with reference to the accompanying drawing and real in order to be more clearly understood that the above objects, features, and advantages of the utility model
Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality
The feature applied in example can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1, the utility model provides a kind of coke oven flue gas denitration desulphurization system, coke oven flue gas is certainly burnt
It after being generated in furnace, is initially entered in activated carbon adsorption device 1 by pipeline, the abundant, specific surface area using activated carbon pore structure
Greatly, the good feature of absorption property carries out preliminary adsorption treatment to flue gas, while active carbon can be to the dust particles in flue gas
Do adsorption treatment simultaneously, the flue gas after the absorption of activated carbon adsorption device 1 enters in plasma purifier 2 through pipeline, when it is equal from
When applied voltage in sub- clarifier 2 reaches gas discharge voltage, flue gas is breakdown, and generating includes electronics, various ions, atom
Mixture with including free radical, makes contaminant molecule decompose in a very short period of time, and subsequent various reactions occur
To achieve the purpose that degradation of contaminant, in order to further remove remaining nitrogen oxides in flue gas, connect after plasma purifier 2
It is connected to mixer 3, from the figure, it can be seen that 3 upper end of mixer is connected with hydrogen peroxide injection device 4, lower end is connected with ozone hair
Why hydrogen peroxide injection device is arranged above mixer 3, ozone generator 5 is arranged below mixer 3 by raw device 5,
Be because of such design so that after the pressurized flue gas of booster fan 6 enters mixer, can with it is top-down double
Sufficiently reaction occurs for oxygen water and ozone from bottom to top, if hydrogen peroxide injection device 4, under, that just needs great pressure to spray
Mouth could by hydrogen peroxide full of in entire mixer 3, not only waste of resource simultaneously, if hydrogen peroxide injection device 4 under, ozone
Generator 5 is upper, because ozone is gas, itself is through the pressurized flue gas pressures of booster fan 6 with regard to larger, while there are also under
If hydrogen peroxide on and, ozone may be cannot be introduced at all in the general volume of mixer 3, also just can not be with flue gas, dioxygen
Water comes into full contact with, so, ozone generator 4 is different from the Position Design of hydrogen peroxide injection device 5, and effect achieved is very much not
Identical, such set-up mode can be such that hydrogen peroxide is sprayed by above and below gravity word, and ozone because lighter in weight from bottom to top with
Hydrogen peroxide, flue gas are sufficiently mixed, by NO, NO in flue gas2It is oxidized to high-valence state N soluble easily in water2O3、N2O5, then enter de-
In sulphur tower 7, it is easier to which nitrogen oxides and sulfur dioxide are absorbed and removed by alkaline desulfurizing agent in desulfurizing tower 7, in order to further
Guarantee emission compliance, it can be seen from the figure that being provided with demister 8, it is preferable to use wet type electrostatic precipitator in the outlet of desulfurizing tower 7
It adsorbs and remaining particulate matter to remove in flue gas without activated carbon adsorption device 1, is then discharged in atmosphere via chimney 9.This
Utility model is adsorbed by conventional carbon and desulfurizing tower denitration desulfurization method and advanced plasma gas cleaning and ozone, double
The mode of oxygen water oxidation technology combination meets the needs of different denitration discharge standard bricks.
It is described, it is only the preferred embodiment of the utility model, is not the limit for making other forms to the utility model
System, any person skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment be applied to other fields, but it is all without departing from the content of the technical scheme of the utility model, it is practical new according to this
The technical spirit of type any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the utility model skill
The protection scope of art scheme.
