Description
(1) technical field:
The present invention relates to a kind of luminous energy purification method and device, particularly a kind of method and device that utilizes light to help Fenton's reaction purifying smoke.
(2) background technology:
Under the form of China's economic sustained and rapid development, energy resource consumption demand sharply rises; Only take coal as example, and since Reformation and development, the demand incremental change of annual coal is greatly about 8～12%, and the maximum dirt disease producing with this is exactly serious air pollution.
The China of today is one of the most serious country of atmosphere pollution in the world (being only second to India).The theme that not long ago special proposition ' eliminated the trouble of common people's cardiopulmonary ' in the regular meeting of State Council of the People's Republic of China; Administer polluting with people's state, the people's livelihood, combining, making a decision to forgo and polluting the cap of big country.Chinese Government determines not only will soar economically also will be for country, the people, offspring and even the world make positive contribution on environment.On the road of China Reconstructs, new cleaning fuel is subject to the restriction of reserves and International Politics and cannot becomes the main alternative kinetic energy of domestic industry demand.Therefore, coal can be still the main kinetic energy energy of China in long-time.Along with industrial requirement constantly increases exhibition, mean that atmosphere pollution will be more serious, effectively alleviate and prevent and remedy pollution and will be forever a heavy problem.
As everyone knows, serious atmosphere pollution meeting brings biologies all on the earth irreversible disaster, and the air polluting is mainly derived from the industrial fumes that contain a large amount of poisonous and harmful substances.These harmful flue dust overwhelming majority produce in coal burning process.Yet, there is no absolute clean coal in the world, the different coal resources of noxious material content proportion that only have the difference because of geological conditions to produce.For example, the coal that NORTH CHINA is produced is high-quality low-sulfur coal, and sulfur content only has 1%～2%; And its sulfur content of the coal that produce Yunnan, Guizhou and Inner Mongol can reach more than 5%.According to measuring and calculating: the sulfur dioxide annual emissions in Chinese industrial flue dust is up to more than 20,000,000 tons.In the city of 113 atmosphere pollution keypoint treatments, there are 40 city SO2 emissions to surpass the secondary standard line that country formulates, 39 cities even are inferior to national grade III Standard line! The Acid Rain Pollution being caused by air pollution has been wreaked havoc the territory of China 1/3rd.Industrial process speedup is faster, and colleague's pollution index will be higher with it, and relevant department is all the more difficult to the control meeting of environment.
Over nearly 20 years Chinese to flue dust desulfurization carried out continual technical research.The pollution of controlling sulfur dioxide with flue gas desulfurization technique is an important step in Environmental Protection in China application.Just with low-sulfur coal (sulfur content 1%), calculate: fire the sulfur dioxide that one ton of coal can produce 16 kilograms (1600x1%, kilogram).Medium-sized coal-burning boiler every day is the coal of 150～200 tons of burnings approximately; That is to say that can produce the sulfur dioxide of 2.4～3.2 tons every day.Current desulfur technology comprises coal be mixed lime or additive; In stove, directly spray calcium and ebullated bed lime stone dry desulfurization; And the wet desulphurization such as calcium alkaline process, ammonia-soda process, soda method, magnesium alkaline process.Through eliminating of practical proof and market economy technology for many years, only have the technical equipment of minority really to enter coal-fired industry boiler applications.Wherein take the tower device of spiral board as at present main application.The tower device of spiral board is in the nineties of flue gas desulfurization and dedusting for coal-fired industry boiler after technological transformation.The advantage of this device is that the contact area of flue gas and liquid is large, simple in structure, resistance is less, stable be main feature.Its shortcoming is that existing technology desulfuration efficiency on average only reaches 60～80%, and cost is very big.The operating cost of desulfurization is now 0.3 yuan every watt, and the annual operating cost in coal-burning power plant of medium-sized 10,002 m. gigawatt (GW)s is 44,300,000 yuan; And the cost of its desulfurizer is 3.6 hundred million yuan! Huge large Installed puts and transports row Charges with really making medium-sized and small enterprises face the crisis of Zhu Bing factory.
Except sulfur dioxide, PM2.5 is causing widely and is paying close attention at present healthy impact.What is particle 2.5 (PM2.5)? they refer to and are combined in small pieces solid or the liquid substance that in earth atmosphere, diameter is less than 2.5 microns.Particle composition can cause obvious visual effect, and as flue dust, it is comprised of sulfur dioxide, nitrogen oxide, carbon monoxide, Mineral Dusts, organic substance and elemental carbon, is also referred to as black carbon or coal smoke.Due to the existence of sulphur, particle is moisture absorption, and SO2 can be converted into sulfuric acid under high humility and low temperature.This by cause visibility reduction, yellow air, ozone, with the suction sense of shouting pain.The impact that the mankind and animal suck particle matter is extensively studied; PM2.5 cause health problem comprise asthma, lung cancer, cardiovascular problems, respiratory disease, birth defect and dead too early.
Granular material dischargedly in most industry country, be all subject to strict supervision.Due to environmental problem, most industries all needs to carry out the operation of certain dust collecting system, granular material discharged to control.These systems comprise centrifugal deduster (cyclone dust), fiber filter deduster (sack cleaner), wet scrubber and electrostatic precipitator.Yet, cheap cleaner efficiency is very low, Tong Chang Da is less than 80%; Good equipment such as the right efficiency of electrostatic precipitation ， Although can be up to 99%, but also have its fatal shortcoming: (1) equipment is huge, and consumption steel is many, needs high-voltage transforming and rectifying installation, therefore invest high.(2) efficiency of dust collection is subject to the restriction of dust specific resistance, general contrast resistance is less than 104～105 ohm every centimeter or be greater than the dust of 1010～1011 ohm every centimeter, if do not take certain measure, efficiency of dust collection will be affected. and (3) do not possess off-line maintenance function, once equipment breaks down, or operation in spite of illness, or can only shutdown maintenance.Generally speaking, any efficient construction of the equipment except PM is all very high with maintenance cost.
China has also proposed the restriction (seeing the following form) to particulate in air discharge, and each factory and enterprise is also all pressed the Regulations cleaner of having Dinged Installed.Yet huge maintenance expense makes medium-sized and small enterprises unable to make ends meet really.Therefore developing an inexpensive and effective dust arrester should be also the task of top priority.

Operation principle of the present invention:
In luminous energy storehouse, by making to use up, help Fenton's reaction and catalysis/oxidation reaction that dust is changed into carbon dioxide, Sulphur Dioxide is become to sulfuric acid.Fenton's reaction is the reaction of a simple photosensitized oxidation/reduction catalysts, and the main feature of Fenton's reaction is that it produces active oxygen (ROS), particularly hydroxyl radical free radical.Hydroxyl radical free radical is the most effective active oxygen, and it can be oxidized any organic (comprising biomolecule) and inorganic matrix at its periphery.Its original chemical reaction is Fe (II) and H
2o
2reaction generates Fe (III) and OH (seeing Fig. 3), and reduction Fe (III) needs the energy of heat or light to Fe (II).In the situation that there is no matrix and substrate and having luminous energy, there are three dominant mechanisms (seeing Fig. 4-6).Light helps the efficiency of Fenton's reaction to depend primarily on H
2o
2concentration, Fe (II)/H
2o
2ratio, pH value, reaction time and UV light intensity.The chemical characteristic of pollutant, physical characteristic, initial concentration and temperature, also have important impact to final efficiency.
Dust in flue gas (main component of haze) is exactly the incomplete coal that burns in fact, the organic substance containing in coal produces imflammable gas after decomposes, also be called as " volatile matter " (VOC), the mist that it is comprised of compounds such as various hydrocarbons, hydrogen, carbon monoxide.When coal combustion condition is up to standard or when the high coal (colm) of volatile matter burns, easily do not produce the minimum carbon granules of uncombusted, be commonly called as " black smoke "; And produce more VOC as nytron pollutants such as carbon monoxide, multiring aromatic hydrocarbon, aldehydes.
The chemical principle of AOPs system is chemical reactivity and its very high oxidizing potential that is that hydroxyl radical free radical You Very is high.The generation of hydroxyl radical free radical can utilize the method for oxidation of Chuan System, as hydrogen peroxide or ozone and ultra-violet radiation/or the combination of catalyst.High intensity UV lamp and Fenton's reaction can react and decompose with any organic and inorganic molecule.Any organic carbonaceous molecule being present in flue gas can be oxidized to CO when it passes bin
