Abstract
The invention discloses a dedusting composition, a desulfuration composition and usages. The dedusting composition comprises a sulfonate type surfactant, a carboxylate type surfactant, an alkyl sulfate type surfactant, a non-ionic anti-static agent and anionic polyacrylamide. The dedusting composition is excellent in dedusting function.
Description
Technical field
The present invention relates to a kind of dedusting composition, desulfurization compositions and purposes, in particular for the dedusting composition, desulfurization compositions and uses thereof of flue gas wet desulphurization process.
Background technology
China is the energy resource consumption big country based on coal, simultaneously Ye Shi iron and steel big producing country.The end of the year 2006, China's coal fired power generation installed capacity reaches 4.84 hundred million kilowatts, coal-fired 1,200,000,000 tons, smoke discharge amount about 3,000,000 tons, and wherein the ultra tiny dust of nearly 2,700,000 tons of PM10 is in atmosphere floating for a long time, particularly PM2.5 is present in air with aerosol form, has a strong impact on atmospheric visibility and air quality.Steel industry dust discharge amount accounts for 25% of China's industrial dust discharged total amount, and sinter that industrial soot emissions account for steel manufacture process total release 40% more than.
Owing to recognizing the harm of flue dust, China has made more strict discharge standard, start on July 1st, 2014 " fossil-fuel power plant atmospheric pollutant emission standard (the GB 13223-2011) " that perform, define existing thermal power generation coal-burning boiler chimney breast soot emissions limit value, the whole nation is 30mg/m
3, the special emission limit in key area is 20mg/m
3; " steel sintering, pelletizing industrial air pollution thing discharge standard (GB 28662-2012) " specifies existing sintering machine ball, and the granular material discharged limit value of group's roasting apparatus is 50mg/m
3, rear of sintering machine emission limit is 30mg/m
3.
For the flue gas that coal-burning boiler and sintering machine are got rid of, usually need just can enter air after the process such as dedusting, desulfurization.In a kind of coal-burning boiler of extensive use or the smoke processing system of sintering machine, flue gas is first through cleaner, and mainly sack cleaner or electrostatic precipitator complete dedusting; Then enter desulphurization plant and carry out desulfurization process.
Sack cleaner utilizes solid or liquid particle in porous filter medium separation and collection gas, and its dust removal process is the dust bonding layer formed after relying on filter medium to run a period of time is main filtration layer, and filter material layer own plays the skeleton function of dust bonding layer.Its principle comprises: sieving, inertial collision, interception, diffusion, electrostatic and gravitational settling.Sack cleaner good dedusting effect, no matter but how high its efficiency is, and the particle major part of discharge is all less than 2.5 μm.
Electrostatic precipitator operation principle utilizes high voltage electric field to make particle charged, under the effect of Coulomb force, make particle and flow separation sedimentation.Electrostatic precipitation drag losses is little, permission operating temperature is high, and process air range amount is large, but has certain selective to dust, to the particle being greater than 10 μm, ESP Efficiency is very high, but when particle diameter is less than 2 μm, efficiency of dust collection will significantly decline, efficiency of dust collection can lower than 90%, in extreme circumstances, efficiency even can drop to less than 50%, from electric cleaner emit quantity maximum be exactly the subparticle of 0.2 ~ 2 μm.
Due to the high-effective dust-removing equipment of routine, as sack cleaner or electrostatic precipitator can not effectively trap for the minuteness particle of particle diameter lower than 2.5 μm, in the flue gas therefore after bag-type dusting or electrostatic precipitation, the content of particle is still at 100 ~ 200mg/m
3, do not meet discharge standard.
Can not one of the new technology of qualified discharge be at present wet static dedusting for making up the two, its operation principle is: metal discharge line is under high direct voltage effect, ambient gas is ionized, dust is charged in power plant, move to dust collecting electrode under electric field force effect, when reaching dust collecting electrode surface, flow down with liquid film and be removed.Wet electrical dust precipitator is to acid mist, and toxic heavy metal and PM10, especially the fine dust of PM2.5 has good removal effect.Therefore, when being applied to coal-burning power plant, sintering machine, wet electrical dust precipitator removes SO for after wet desulphurization
3, water droplet and flue dust effect clearly.
But, after wet cottrell must be placed in desulphurization plant, namely the flue gas that coal-burning boiler or sintering machine are got rid of needs first to carry out desulfurization through desulphurization plant, then just can enter wet cottrell and carry out dedusting, thus can increase the running resistance of desulphurization plant.Further, it adopts closing circulation irrigating water, need constantly fill into former water, discharges waste water, increases desulphurization system water balance difficulty.In addition, the technical costs of wet electrical dust precipitator single product is high, equipment investment expense is higher than common electrostatic duster, and in running except the power consumption of deduster own, auxiliary water circulating pump etc. also can consume part electricity, in flushing water, additive also increases a part of operating cost, and therefore it drops into and operating cost all too costliness.
CN104014210A discloses a kind of method adopting liquid membrane emulsion technology to remove dust in flue gas, but emulsion liquid film complicated process of preparation, and be not suitable for using with other slurry combination, range of application is narrower.
CN104355386A discloses a kind of composite flocculation agent be made up of polyacrylamide and polyacrylamide sodium, but it effectively can not remove the fine particulates of particle diameter below 2.5 μm.
CN103721550A discloses a kind of flue gas and desulfurizing and denitrifying and takes off VOCs absorbent, comprises ammonium salt (ammonium chloride, ammonium carbonate, triethanolamine and urea) 5 ~ 10%, surfactant (castor oil sodium sulfonate, aliphatic alcohol polyethenoxy polypropylene ether, Tween-20 and Si Ban-20) 0.01 ~ 0.50%, complexing agent (ethylenediamine tetra-acetic acid ferrous complex, aminotriacetic acid ferrous complex and six cobaltammines) 1 ‰ ~ 2% and excess water.SO in high-efficient purification flue gas while that this absorbent can be implemented in a set of equipment
2, NO
xwith VOCs etc., but dust removing effects still awaits improving.
