In the process, sulfur-containing and nitrate-containing flue gas, a cooling system, a low-temperature plasma module 1, a low-temperature plasma module 2, a plasma mixer, air, an ammonia mixer, ammonia water, a wet-type electrostatic precipitator and clean gas are involved. The process is used for treating the sulfur-containing and nitrate-containing flue gas; through an oxidation reaction provided by the low-temperature plasma modules and in combination with a reduction reaction of the ammonia water, an optimal process object of desulfurization, denitration and demercuration at the same time through a single flow path can be achieved, and the effects that the desulfurization efficiency is higher than or equal to 95%, the denitration efficiency is higher than or equal to 85% and the demercuration efficiency is higher than or equal to 85% are achieved; meanwhile, the process has the advantages of low using cost and low maintenance cost.
Description
Technical field
The present invention relates to a kind of flue gas treating process, and in particular to a kind of plasma advanced oxidation fume treatment work
Skill.
Background technology
Existing traditional fume treatment technology although technology maturation, but still have that techniqueflow is complicated, equipment is huge,
Complex management, efficiency is unstable, cannot the defect such as demercuration.If especially middle-size and small-size fume treatment uses biography
System fume treatment technology cannot then bear it and build, manages and operating cost.So one kind can desulfurization simultaneously
Denitration demercuration, but energy operational management is convenient, and the rational smoke processing system of cost becomes trend of the times.
The content of the invention
To solve existing conventional technical drawback, the present invention seeks to low-temperature plasma oxidation technology is rationally utilized,
Make and possess high efficiency, the single process flue gas treating process of low energy consumption simultaneous SO_2 and NO removal demercuration ability.
Disclose a kind of plasma advanced oxidation flue gas treating process, including sulfur-bearing gas containing the smoke of gunpowder, cooling system,
Low-temperature plasma module 1, low-temperature plasma module 2, plasma blender, air, ammonia blender, ammoniacal liquor,
Wet electrical dust precipitator, clean gas, it is characterised in that：
The sulfur-bearing gas containing smoke of gunpowder Jing cooling systems cooling first, it is then laggard by low-temperature plasma module 1
Enter plasma blender, enter back into ammonia blender, finally enter wet electrical dust precipitator, be changed into clean after process
Gas.
A kind of described plasma advanced oxidation flue gas treating process, it is characterised in that the low-temperature plasma
Module 2 is connected with plasma blender, and idiographic flow is that air is noted Jing after the ionization of low-temperature plasma module 2
Enter plasma blender.
A kind of described plasma advanced oxidation flue gas treating process, it is characterised in that the ammonia blender,
There is ammoniacal liquor to inject.
Beneficial effects of the present invention：
1st, single process technique solves flue gas desulfurization, denitration, a demercuration difficult problem, and treatment effeciency can reach desulfuration efficiency
>=95%, denitration efficiency >=85%, the effect of demercuration efficiency >=85%.
2nd, process operation expense is low, and maintenance cost is low.
Description of the drawings
Fig. 1 is the process chart of the present invention
Specific embodiment
In order that technical scheme is it is more readily appreciated that with reference to specific embodiment and accompanying drawing to this
It is bright further to be introduced.
With reference to Fig. 1, a kind of plasma advanced oxidation flue gas treating process, including sulfur-bearing gas containing the smoke of gunpowder, cooling system
System, low-temperature plasma module 1, low-temperature plasma module 2, plasma blender, air, ammonia blender,
Ammoniacal liquor, wet electrical dust precipitator, clean gas.
The sulfur-bearing gas containing smoke of gunpowder Jing cooling systems cooling first, it is then laggard by low-temperature plasma module 1
Enter plasma blender, enter back into ammonia blender, finally enter wet electrical dust precipitator, be changed into clean after process
Gas.Low-temperature plasma module 1 produces plasma by dielectric barrier discharge, is directly connect with flue gas
Touch oxidation.
The low-temperature plasma module 2 is connected with plasma blender.Low-temperature plasma module 2 is medium resistance
Gear electric discharge produces plasma, and plasma blender is injected after ionized air, makes plasma internal mixer
Flue gas obtains higher oxidation.Smoke components after oxidation are changed into the oxidation product of high-valence state, it is easier to liquid
Body mixes, and is easier and ammoniacal liquor reaction.
The ammonia blender, has ammoniacal liquor to inject.Flue gas after oxidized fully reacts in ammonia blender, cigarette
Sulfur dioxide and nitrogen oxides, mercury in gas is changed into a large number callable inorganic salts and innocuous gas.
The wet electrical dust precipitator, reaction residual matter is removed and collected, so as to obtain clean gas.
Below the present invention disclosed with preferred embodiment, so it is not intended to limiting the invention, it is all using etc.
With the technical scheme replaced or equivalent transformation mode is obtained, it is within the scope of the present invention.
