The ozone and smoke mixed plasma excitation reaction device is characterized in that the oxygen-enriched machine, the ozone generator and the plasma excitation mixed reactor of the device are sequentially connected with one another through pipelines. Compared with the conventional desulfurization and denitrification technology, the ozone and smoke mixed plasma excitation reaction device has the advantages that the desulfurization rate is higher than or equal to 95%, the denitrification rate is higher than or equal to 90%, absorption liquid is converted into magnesium sulfate and magnesium nitrate double salt through strong oxidation treatment, the reutilization of pollutants is realized, and the national clean production concept, namely wastewater zero discharging, is advocated.
Description
Technical field
Excitation of plasma reaction unit and method that a kind of ozone of the utility model, flue gas mix relate to environmental technology field, particularly flue gas desulfurization and denitrification field, and the flue gas that is applied to desulphurization denitration mixes with reaction and excites.
Background technology
China power plant is at present take the thermal power plant as main; desulphurization denitration is the object that discusses of 12 planning; " national environmental protection " 12 " planning " has also made the guarantee of policy to desulphurization denitration; the Air Pollutant Emission total amount continues to subdue during " 12 "; require national SO2 total emission volumn to reduce 10% than 2010, key industry and key area NOx total emission volumn reduced 10% than 2010.Present domestic desulphurization denitration technology exists also that cost is high, removal efficiency is low, cause the deficiencies such as serious secondary pollution, plant maintenance difficulty.
The utility model content
The purpose of this utility model is to overcome defects, prior art is improved, use a kind of ozone in flue gas, to mix the excitation of plasma reaction unit on the basis of original magnesia desulfur technology, flue gas is mixed with ozone, under excitation of plasma, react, absorb by the absorption tower, reach and reduce desulphurization denitration cost, raising removal efficiency so that pollutant is processed resource, do not produce excitation of plasma reaction unit and method that secondary pollution and plant maintenance are easy to a kind of ozone, flue gas mixing.
Its technology is achieved in that and comprises oxygen enricher, ozone generator, excitation of plasma mixing reactor, it is characterized in that: whole device passes through pipeline, be linked in sequence by oxygen enricher, ozone generator, excitation of plasma mixing reactor, described oxygen enricher is comprised of oilless (oil free) compressor, refrigeration compressor, freeze drier, filter, PSA dryer, described ozone generator is comprised of electrion chamber, cooling water system, electric-control system, and described excitation of plasma mixing reactor is comprised of discharge electrode, air vibrated system, electric-control system.The obvious advantage of implementing after this technology with effect is: compare with existing desulphurization denitration technology, so that desulfuration efficiency desulfuration efficiency 〉=95%; Denitration rate 〉=90%, absorption liquid is converted into magnesium sulfate magnesium nitrate double salt through strong oxidation processes, realizes pollutant processing resource, advocates national cleaner production theory----wastewater zero discharge.

Fig. 1 is the utility model overall structure schematic diagram.
Number in the figure, 1. oilless (oil free) compressor, 2. refrigeration compressor, 3. lyophilized preparation, 4. filter, 5.SPA dryer, 6. the electrion chamber, 7. cooling water system, 8 excitation of plasma back mixing are closed and are answered device, 9. flue.
The specific embodiment
Below in conjunction with accompanying drawing, take embodiment as example, the utility model is further described:
As shown in Figure 1, whole device is linked in sequence by oxygen enricher, ozone generator, excitation of plasma mixing reactor by pipeline.Oxygen enricher is comprised of oilless (oil free) compressor, refrigeration compressor, freeze drier, filter, PSA dryer, institute's ozone generator is comprised of electrion chamber, cooling water system, electric-control system, and the excitation of plasma mixing reactor is comprised of discharge electrode, air vibrated system, electric-control system.
As shown in Figure 1, air is improved by the rear oxygen concentration of oilless (oil free) compressor 1 compression, enter refrigeration compressor 2, then by freeze drier 3, filter 4, PSA dryer 5 carries out drying and removes oil, finish the enrichment of oxygen behind the impurity such as steam, oxygen-enriched air enters ozone generator 6, produce ozone by electrion, enter excitation of plasma mixing reactor 8 from ozone generator 6 ozone out, under the effect of excitation of plasma mixing reactor, mix with ozone with the flue gas that enters simultaneously, and under excitation of plasma, react, the key reaction that NO occurs in ozone and the flue gas is:
NO+O

E* is high energy electron, and e is general electronics.
Strong oxidic particle also can oxidation NO, increases oxidation effectiveness.
Mixed flue gas from the excitation of plasma mixing reactor out enters the absorption processing of next stage.Absorption liquid is converted into magnesium sulfate magnesium nitrate double salt through strong oxidation processes, realizes pollutant processing resource.
