Description
(1) technical field:
The present invention relates to a kind of luminous energy purification method and device, a kind of utilize light to help Fenton's reaction purifying smoke
Method and device.
(2) background technology:
Under the form of China's economic sustained and rapid development, energy resource consumption demand steeply rises;Only as a example by coal, reform
Since exploitation, the demand incremental change of annual coal is about 8~12%, and the maximum dirt disease produced with this is exactly serious air
Pollute.
The China of today is one of the most serious country of atmospheric pollution in the world (being only second to India).Not long ago in state of China
The theme proposing ' eliminating the trouble of common people's cardiopulmonary ' special in the regular meeting of business institute;Pollution administration has been combined with people's state, the people's livelihood
Come, make a decision to forgo and pollute the medicated cap of big country.Chinese Government determine not only to soar economically also will in the environment for country,
The people, offspring or even the world make positive contribution.On the road of China Reconstructs, new cleaning fuel is by reserves and state
Border politics restriction and the replacement kinetic energy that domestic industry demand is main cannot be become.Therefore during, coal can be the most still
The kinetic energy energy that state is main.Constantly increase exhibition along with industrial requirement and mean that atmospheric pollution will be more serious, effectively alleviate with anti-
Pollution treatment dye will be a heavy problem forever.
It is known that serious atmospheric pollution can bring the irreversible disaster of all of biology on the earth, and pollute
Air is mainly derived from the industrial fumes containing a large amount of poisonous and harmful substances.These noxious fume overwhelming majority is by coal burning
Produced by during.But, there is no absolute cleaning coal in the world, only produce because of the difference of geological conditions is poisonous
The coal resources that content of material proportion is different.Such as, the coal that NORTH CHINA is produced is the low-sulfur coal of high-quality, and sulfur content only has 1%
~2%;And its sulfur content of coal that Yunnan, Guizhou and Inner Mongol are produced can reach more than 5%.According to measuring and calculating: in Chinese industrial flue dust
Sulfur dioxide annual emissions be up to more than 20,000,000 tons.In the city of 113 atmospheric pollution keypoint treatments, there are 40 cities
SO2 emissions exceed the secondary standard line of country's formulation, and 39 cities are even inferior to country's grade III Standard line!By air
Pollute the Acid Rain Pollution caused and wreak havoc the territory of China 1/3rd.The fastest pollution gone together therewith of industrial process speedup refers to
Number will be the highest, and relevant department can be the most difficult to the control of environment.
Chinese over nearly 20 years continual technical research is carried out in flue dust desulfurization.Dioxy is controlled with flue gas desulfurization technique
The pollution changing sulfur is an important step in Environmental Protection in China application.Just calculate with low-sulfur coal (sulfur content 1%): combustion one
Ton coal can produce the sulfur dioxide of 16 kilograms (1600x1%, kilogram).One medium-sized coal-burning boiler about burn every day 150~
The coal of 200 tons;That is the sulfur dioxide of 2.4~3.2 tons can be produced every day.Current desulfurization technology includes coal mixture stone
Ash or additive;Calcium and ebullated bed limestone dry desulfurization is directly sprayed in stove;And calcium alkaline process, ammonia-soda process, sodium alkali, magnesium alkaline process
Deng wet desulphurization.Eliminating through practical proof for many years and market economy technology, the only technical equipment of minority actually enters combustion
Coal industry boiler applications.Wherein with spiral board towers units for currently mainly application.Spiral board towers units is in the nineties
For flue gas desulfurization and the dedusting of coal-fired industry boiler after technological transformation.The advantage of this device is connecing of flue gas and liquid
Contacting surface is long-pending greatly, simple in construction, resistance are less, stable for main feature.Its shortcoming is then that existing technology desulfuration efficiency is put down
All only reach 60~80%, and cost is very big.The operating cost of desulfurization now is 0.3 yuan every watt, and one medium-sized by 12,000
Megawatt the annual operating cost in coal-burning power plant be 44,300,000 yuan;And the cost of its desulfurizer is 3.6 hundred million yuan!
Huge puts and runs with the crisis really making medium-sized and small enterprises face work factory.
Except sulfur dioxide, healthy impact has been caused at present and has paid close attention to widely by PM2.5.What is particulate matter
2.5(PM2.5)?They refer to be combined in small pieces of solid or the liquid substance that diameter in earth atmosphere is less than 2.5 microns.Particulate matter
Compositions can cause obvious visual effect, such as flue dust, it by sulfur dioxide, nitrogen oxides, carbon monoxide, Mineral Dusts, have
Machine material and elemental carbon composition, also referred to as black carbon or coal smoke.Due to the existence of sulfur, granule is moisture absorption, and SO2 meeting
It is converted into sulphuric acid under high humility and low temperature.This will cause visibility reduction, yellow air, ozone and the suction sense of twinge.People
The impact that class sucks particle matter with animal has been extensively studied;What PM2.5 caused health problem includes asthma, lung
Cancer, cardiovascular problems, respiratory system disease, birth defect and premature death.
Granular material discharged the most strictly supervised in most industry country.Due to environmental problem, most industries is all
Need to carry out the operation of certain dust collecting system, granular material discharged to control.These systems include that (eddy flow removes centrifugal deduster
Dirt device), fiber filter cleaner unit (sack cleaner), wet scrubber and electrostatic precipitator.But, cheap cleaner
Efficiency is the lowest, and typically less than 80%;Good equipment such as electrostatic precipitation, right efficiency may be up to 99%, but also has it fatal
Shortcoming: (1) equipment is huge, consumption steel is many, needs high-voltage transforming and rectifying installation, therefore investment is high.(2) efficiency of dust collection is by dust specific resistance
Restriction, the general contrast resistance dust less than 104~105 ohm every centimeter or more than 1010~1011 ohm every centimeter, if
Not taking certain measure, efficiency of dust collection will be affected. and (3) do not possess off-line maintenance function, and once equipment breaks down, or
Run in spite of illness, or can only shutdown maintenance.Sum it up, it is all very that any effective percentage is built with maintenance cost except the equipment of PM
High.
China also has been presented for the restriction (see table) to particulate in air discharge, and each factory and enterprise is the most all pressed fixed
Cleaner.But huge maintenance expense makes medium-sized and small enterprises unable to make ends meet really.Therefore development one is inexpensive and effective
Dust arrester also should be the task of top priority.

The operation principle of the present invention:
In luminous energy storehouse, help Fenton's reaction and catalysis/oxidation reaction that dust is changed into carbon dioxide by making to use up,
Sulphur Dioxide is become sulphuric acid.Fenton's reaction is a simple photosensitized oxidation/reduction catalysts reaction, the master of Fenton's reaction
Wanting feature is that it produces active oxygen (ROS), particularly hydroxyl radical free radical.Hydroxyl radical free radical is maximally effective active oxygen, and it is permissible
Aoxidize any organic (including biomolecule) and inorganic matrix at its periphery.Its original chemical reaction is Fe (II) and H2O2
Reaction generates Fe (III) and OH (see Fig. 3), and reduction Fe (III) to Fe (II) needs heat or the energy of light.There is no substrate and the end
Thing and in the case of having luminous energy, has three dominant mechanisms (see Fig. 4-6).Light helps the efficiency of Fenton's reaction to depend primarily on H2O2
Concentration, Fe (II)/H2O2Ratio, pH value, the intensity of response time and UV light.The chemical characteristic of pollutant, physical characteristic,
Initial concentration and temperature, also have important impact to final efficiency.
Dust (main component of haze) in flue gas burns incomplete coal the most exactly, and the organic substance contained in coal exists
Producing imflammable gas after decomposes, also referred to as " volatile matter " (VOC), it is by various Hydrocarbon, hydrogen, an oxygen
Change the mixed gas of the compound compositions such as carbon.When coal combustion condition is the most up to standard or volatile matter high coal (colm) burning time easy
Produce the carbon granules that uncombusted is minimum, be commonly called as " black smoke ";And produce the carbon such as more VOC such as carbon monoxide, multiring aromatic hydrocarbon, aldehydes
Pollutant are closed in hydrogenation.
The chemical principle of AOPs system be hydroxyl radical free radical have high chemical reactivity and its very
High oxidizing potential.The generation of hydroxyl radical free radical can utilize the method for oxidation of biography, such as hydrogen peroxide or ozone and ultraviolet spoke
Penetrate/or the combination of catalyst.High intensity UV lamp and Fenton's reaction can react with any organic and inorganic molecule and decompose.
Any organic carbon-containing molecule being present in flue gas can be oxidized to CO when it is through bin2, other heavy metals and inorganic ore deposit
Thing then can be deposited in the fiber removal of mercury filter in our discharge duct.Hydroxyl radical free radical and the dominant response of organic substance
It is exactly can be by organic substance decomposition progressively.Hydroxyl radical free radical and Hydrocarbon first reaction in flue gas in luminous energy storehouse
Being to remove a hydrogen atom in its molecular structure (R), then form water and alkyl diradical (R) (see Fig. 7), second anti-
Should be that alkyl diradical (R) reacts rapidly formation peroxy radical (see Fig. 8), more again through many with molecular oxygen
Step, ultimately generates carbon dioxide and water.Hydroxyl radical free radical can be with Quick Oxidation SO2So that industrial utilize at Fenton's reaction
The reason waste gas containing sulfur dioxide is possibly realized, SO2With hydroxyl radical free radical effect, form SO3, form sulphuric acid the most in the solution
(see Figure 10).
Additionally, the generation of hydroxyl radical free radical is also by other light reaction, such as ozone/ultraviolet or peroxidating dioxy
Changing titanium/hydrogen/solar radiation also to be able to realize, it is high (from 63 to 10 that the feature of Fenton's reaction is exactly its reaction rate constant5),
And other luminous energy reaction such as reaction of ozone/ultraviolet, speed constant is only 10-6Left and right.Flue gas in trachea with 6 meters per second
Speed before, without high reaction efficiency, any chemical reaction all methods are carried out.
The technical program is also added into 'alpha '-hydroxy acids to improve the volume of production of OH.Glycolic, acetone acid and lactic acid all may be used
To add in luminous energy storehouse, help speed up the speed of Fenton's reaction and the formation of hydroxyl radical free radical.'alpha '-hydroxy acids is not own
It is not involved in Fenton's reaction, but it can stablize the formation of OH to increase the yield of OH.It can also keep the pH value in storehouse
Less than 3 to guarantee that luminous energy storehouse has the light reaction environment of optimum.
Due to the corrosivity of the sulphuric acid (sulphuric acid of 20%~70% concentration its corrosivity ratio 98% different according to intensity
The sulphuric acid of concentrations above is taller), so storehouse has been coated with the Teflon of 2~3 millimetersWith anticorrosion.
The superiority of the present invention: 1, the advantage of nano material is that its surface area is big, and between molecule, electronic shell transfers mutually
Very fast, can make to accelerate as chemical reaction velocity index;Especially in optical field, the work of the least luminous energy of diameter of nanometer
Property is the biggest with momentum.So wanting that the flue gas making flow velocity the fastest produces any chemical reaction, the advantage of nanotechnology is could not
Fixed.The redox reaction of self is spontaneous, has the characteristic of catalyst, so without often attaching, consumption is few, very
Economy.2, this invention desulfurization benefit can reach 99.99%, and be manufactured into and run all on 50% left side of current desulfurization technology
The right side, and in the case of there is no any extra charge, solve the removal problem of PM2.5.Equipment occupation of land is little, transformation is simple.This
Invention is set up and is helped in the principle of Fenton's reaction at light, and is eliminating SO2With achieve immense success on flue dust.Of the present invention set
Standby it is principle based on AOPs-Fenton's reaction and successful industrialized unit.The method of the invention be one more economical, higher
The mode controlling air pollution of effect, it is not necessary to any extra manufacture and operating cost.It is existing that it can be included into coal-burning boiler
Some dust pelletizing systems are for improving its effectiveness, it is also possible to replace original old system completely.The present invention is the most applicable at other
Industrial market, including cement plant, steel plant, trash burning factory of municipal government, clinical waste combustion plant, chlorine maker, paper pulp
With paper production factory etc..On the premise of following strictly rule of operation, technique can be protected continuity and use by 15~20 years without entering
