Description
Technical field
The present invention and a kind of for removing so2, nox in industrial smoke and micron order aerosol smoke particle one
The integration unit of body, this is using alternation high voltage electric field soaking, by o3 and so2, nox in flue gas change into rapidly so3,
After no3, then with straight high voltage electric field, so3, no3 negative ionization is processed, with aqueous solution, negative ion so3, no3 is reclaimed,
Ultimately generate a kind of arc type desulphurization denitration device of sulphuric acid and nitric acid.
Background technology
It is known: at present, China's energy is based on fire coal, and metal smelt process, can produce a large amount of sulfur dioxide,
At present, up to 40,000,000 tons of the annual SO2 emissions of China, this is to cause haze one of the main reasons today, and these
Sulfur dioxide in flue gas concentration high more than 10%, and low less than 1%, it is very big that this results in recovery difficult.For many years, I
State puts into in the desulfurization project built, and major part is all to adopt with calcium base wet-process flue gas desulfurization for main Treatment process.Calcio is wet
Generally using Calcium Carbonate and calcium oxide as desulfurizing agent, desulfurization product is Gypsum Fibrosum, and the gypsum resource of China enriches for method flue gas desulfurization,
After desulfurization, its impurity of Gypsum Fibrosum is too many, and canopy pine is unreal, does not have use value, but cannot process, and becomes pollution source, real
On border, this is the technology substituting another kind of pollution with a kind of pollution modes, even so, the cost due to this sulfur removal technology technology
Too high, desulfurization product can not bring benefits again, it has also become the great burden that can't stand is held by enterprise, and [a large desulfurization denitration sets
Standby, annual operating cost is up to tens million of units, a small-sized heating station, and the operating cost in a winter also needs millions of units ,] this just compels
Make producer in order to cost-effective, using desulphurization plant mostly as dealing with inspection, the image actually all really not put into operation
Engineering, makes the sulfur dioxide in flue gas, does not mostly all have treated just directly row to be steathily put into steathily in air, this is in industry already
The fact that well-known；This is also China's main basic reason that today, haze was administered more serious and more serious！But, on the one hand, sulfur is again
It is the essential important source material of China's industrial and agricultural production, and China is due to sulfur mineral resources very little, China's gas washing in SA production, always
It is to rely on a large amount of imported sulphur to carry out processing, if, a kind of low cost of invention, the novel desulphurization technique setting of process is simple,
By sulfur dioxide in industrial smoke for producing into sulphuric acid, to substitute the sulphuric acid of sulfur cream！This just can be directly by this
Main atmospheric pollution poison source, transforms into huge resource, therefore, the sulfur dioxide low cost conversion in industrial smoke is produced into
Sulfur process, is the green technology of the most preferable doulbe-sides' victory.Consequently, it is possible to this will make desulfurization reduce discharging, become manufacturing enterprise and feel certainly
It is willing to the profit project changing harmful to treasure being accepted, thus will thoroughly prevent to arrange the part generation put steathily steathily！Obtain in haze
While to effect a radical cure, the huge foreign exchange buying sulfur can also be saved for country.
Sulfur dioxide in industrial smoke is processed into sulphuric acid, this at home and abroad early has sub-fraction producer and has this
Aspect transformation technology facility, but all because its technique is excessively complicated, operating cost is too high, the cost especially producing ozone is too high,
Therefore, so far also only only tens of thousands of, should be used in ten tens of thousands of low discharges settings, it is difficult to the large-scale generating in millions of air quantity
Application is realized on factory.
Therefore, haze to be made obtains real improvement, need newly a kind of new and effective cheap sulfur removal technology technical side
Method.
Content of the invention
In order to overcome the shortcomings of existing sulfur removal technology technology presence, for making the so2 containing in industrial smoke obtain thoroughly
Effectively reclaim.It is an object of the invention to provide a kind of arc type desulphurization denitration device and its manufacture method.
The present invention solves technical problem and be employed technical scheme comprise that.
First, invent a kind of high intensity alternating electric field exciting bank, under the excitation of high-voltage alternating electric field, will be smelly in flue gas
Oxygen (o3) changes into rapidly so3, (so2+o3=so3+o2) with contained so2 in flue gas.
2nd, invent a kind of new so3 retracting device, new so3 retracting device electronics radiates by force, by charged for so3 one-tenth
For negative ion, then negative ion so3 is injected in the water of positively charged, make the so3 of negative ion rapid and positively charged
Water contact is fused, ultimately produces sulphuric acid and is reclaimed (so3 (l)+h2o (l)=h2so4).(nox conversion nitric acid and this phase
With)
The beneficial effect of arc type desulphurization denitration device is.
1. arc type desulphurization denitration device, is collection desulphurization and denitration, dust removal integrated comprehensive device, also can be dedicated for
The technique device of a certain special cleaning.So2 in industrial smoke can be removed more than 99%, the discharge dust-laden after desulphurization and denitration is dense
Degree can drop to below 1mg/nm.
2. arc type desulphurization denitration device, its desulphurization and denitration, dedusting, its function admirable, compact, especially with smelly
Oxygen (o3) and water make reducing agent, and cost operating cost is extremely low, and process structure is simple, convenient for installation and maintenance.
3. arc type desulphurization denitration device, the antacid solving the problems, such as so2, nox low concentration smelting frost smoke gas difficult it is adaptable to work
The flue gas desulfurization of any concentration of so2, nox in industry flue gas, denitration.
4. arc type desulphurization denitration device, not only has good removal effect to so2, nox in industrial smoke, and right
Other noxious pollutants in flue gas, such as heavy metal Hg also have certain Scavenging activity.
5. arc type desulphurization denitration device, uses as devulcanizer Ru single, and final product is sulphuric acid, due to desulphurization system fortune
Row low cost, can be enterprise's extra earning, be no longer the burden that enterprise can't bear to bear, it will make this air primary pollution source, turn
It is melted into as enormous industrial resource.It is the green technology of preferable doulbe-sides' victory.At the same time it can also save the outer of huge purchase sulfur for country
Converge.
6. arc type desulphurization denitration device, if not adopting ozone, is directly used as desulphurization denitration transforming agent, finally with ammonia
Product can become ammonium sulphate, nitric acid ammonification fertilizer.
7. arc type desulphurization denitration device, uses as cleaner unit Ru single, and the little electric field arrangement of only one can substituted volume
The electric cleaner of huge, multiple electric fields, this technology is suitable for any concentration industrial fumes cleaning, has recovery below pm2.5 micron

Generate sulphuric acid and nitric acid (so3 (l)+h2o (l)=h2so4).
If simultaneously when there is smokeshade in air-flow also can be equally by DC high voltage electric field discharging rod (3) upper electricity fire
Charged, the charged rear smokeshade of negatron that Hua Sai (1) is radiated, will be separated with gas after entering in water, can dissolve in
Precipitate in the water of positively charged, after dust flows through Water warfare, spray from demarcation strip (7) hole, enter in casing b, then through removing
After wet device (12) dehumidifying, from air port (5) row, when in water tank (9), h2so4 accumulation reaches required concentration, from water slurry row
Valve (11) is arranged.
This technique also can use ammonia to substitute ozone (o3), fertile for ammonium sulphate synthetically produced with so2, nox, nitric acid ammonification).
Figure 10 is in embodiment, and on demarcation strip (7), arrangement divides hole.On hollow pipe (8) wall, arrangement point has
Hole.
