Description
Technical field
The present invention relates to a kind of dedusting composition, desulfurization compositions and purposes, in particular for flue gas wet desulphurization process
Dedusting composition, desulfurization compositions and application thereof.
Background technology
China is the energy resource consumption big country based on coal, simultaneously Ye Shi iron and steel big producing country.In the end of the year 2006, China's fire coal is sent out
Electricity installed capacity reaches 4.84 hundred million kilowatts, coal-fired 1,200,000,000 tons, smoke discharge amount about 3,000,000 tons, and the most about 2,700,000 tons
The ultra tiny dust of PM10 is the most floating in atmosphere, and 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 the 25% of China's industrial dust discharged total amount, sintering industry
Soot emissions account for the 40% more than of steel manufacture process total release.
Owing to recognizing the harm of flue dust, China has made the strictest discharge standard, opens on July 1st, 2014
Begin " fossil-fuel power plant atmospheric pollutant emission standard (the GB 13223-2011) " performed, it is stipulated that existing thermal power generation coal-burning boiler
Chimney breast soot emissions limit value, the whole nation is 30mg/m3, the special emission limit in key area is 20mg/m3；" steel sintering, ball
Group's industrial air pollution thing discharge standard (GB 28662-2012) " specify existing sintering machine ball, group's roasting apparatus is granular material discharged
Limit value is 50mg/m3, rear of sintering machine emission limit is 30mg/m3。
The flue gas that coal-burning boiler and sintering machine are got rid of, it usually needs just can enter after dedusting, desulfurization etc. process
Air.In the smoke processing system of a kind of wide variety of coal-burning boiler or sintering machine, flue gas first passes around cleaner, main
If sack cleaner or electrostatic precipitator complete dedusting；Desulfurization process is carried out subsequently into desulphurization plant.
Sack cleaner utilizes solid or liquid particle in porous filter medium separation and collection gas, and its dust removal process is to depend on
The dust bonding layer formed after running a period of time by filter medium is main filtration layer, and filter material layer own plays the bone of dust bonding layer
Frame effect.Its principle includes: sieving, inertial collision, intercepts, diffusion, electrostatic and gravitational settling.Sack cleaner dust removing effects
Good, no matter but how high its efficiency is, and the particulate matter major part of discharge is both less than 2.5 μm.
Electrostatic precipitator operation principle is to utilize high voltage electric field to make particulate matter charged, Coulomb force act under make particulate matter with
Air-flow separates sedimentation.Electrostatic precipitation drag losses is little, it is allowed to operation temperature is high, and it is big to process air range amount, but has dust
Certain selectivity, to the particulate matter more than 10 μm, ESP Efficiency is the highest, but when particulate matter diameter is less than 2 μ
During m, efficiency of dust collection will be remarkably decreased, and efficiency of dust collection can be less than 90%, in extreme circumstances, efficiency even can drop to 50% with
Under, from electric cleaner emit quantity most be exactly the subparticle of 0.2～2 μm.
Owing to conventional high-effective dust-removing equipment, such as sack cleaner or electrostatic precipitator are less than the micro-of 2.5 μm for particle diameter
Fine particle can not effectively trap, and therefore in the flue gas after bag-type dusting or electrostatic precipitation, the content of particulate matter is still 100
～200mg/m3, do not meet discharge standard.
Being currently used for making up the two can not one of the new technology of qualified discharge be wet static dedusting, and its operation principle is:
Ambient gas, under high direct voltage effect, is ionized by metal discharge line, and dust is charged in power plant, to collection under electric field force effect
Dirt polar motion, when reaching dust collecting electrode surface, flows down with liquid film and is removed.Wet electrical dust precipitator to acid mist, toxic heavy metal with
And the fine dust of PM10, especially PM2.5 has good removal effect.Therefore, when being applied to coal-burning power plant, sintering machine, wet
Formula electric cleaner is for removing SO after wet desulphurization3, water droplet and flue dust effect clearly.
But, after wet cottrell must be placed in desulphurization plant, the flue gas that i.e. coal-burning boiler or sintering machine are got rid of
Need to first pass around desulphurization plant and carry out desulfurization, then could enter wet cottrell and carry out dedusting, thus can increase de-
The running resistance of sulphur equipment.Further, it uses closing circulation irrigating water, need to constantly fill into former water, discharges waste water, increases desulfurization
Systematic water balance difficulty.Additionally, the technical costs of wet electrical dust precipitator single product is high, equipment investment expense is higher than common electrostatic
In deduster, and running in addition to the power consumption of deduster own, the water circulating pump of auxiliary etc. also can consume part electricity, rinses
In water, additive also increases a part of operating cost, and therefore it puts into and operating cost is the most prohibitively expensive.
CN104014210A discloses and a kind of uses liquid membrane emulsion technology to remove the method for dust in flue gas, but emulsion
Film preparation complex process, and be not suitable for using with other slurry combination, range of application is narrower.
CN104355386A discloses a kind of composite flocculation agent being made up of polyacrylamide and polyacrylamide sodium, but its
Can not effectively remove particle diameter fine particulates below 2.5 μm.
CN103721550A discloses a kind of flue gas and desulfurizing and denitrifying and takes off VOCs absorbent, including ammonium salt (ammonium chloride, carbon
Acid ammonium, triethanolamine and urea) 5～10%, surfactant (castor oil sodium sulfonate, aliphatic alcohol polyethenoxy polypropylene ether, tells
Temperature-20 and Span-20) 0.01～0.50%, complexing agent (ethylenediamine tetra-acetic acid ferrous complex, aminotriacetic acid ferrous iron be complexed
Thing and six cobaltammines) 1 ‰～2% and excess water.The while that this absorbent can be implemented in a set of equipment in high-efficient purification flue gas
SO2、NOXWith VOCs etc., but dust removing effects still await improve.
