Description
Technical field
Flue gas desulfurization technique field is the utility model is related to, especially a kind of eddy flow phase transformation sieving flue gas desulfurization complementary energy recovery
Integrated reactor.
Background technology
China is the big developing country of an energy resource structure heavy dependence coal consumption, and national coal consumption amount is high within 2013
Up to 36.1 hundred million tons, and with the high speed development of social economy, coal consumption amount will continue to increase.Element containing sulphur in coal,
The overwhelming majority is oxidized to SO in coal burning2If arranged without effective, directly with fume emission air, incite somebody to action
Heavy damage ecological environment, high risks are caused to the health of the mankind.
Flue gas desulfurization technique (FGD) is presently the most one of effective and widely used flue gas polution control technology.Extensively
For the industry flue gas such as thermal power generation, Ferrous Metallurgy SO2Improvement, in flue gas desulfurization technique, wet method lime stone flue gas desulfurization
Technology is current with most, and FGD techniques the most ripe, in wet method limestone desulfurization technology, from drawing
The flue gas of blower fan enter the slurry droplet that sprays downwards of spraying layer in absorption tower, with absorbing tower carry out efficiently, sufficiently " gas-
Liquid " contacts, and washs SO2、SO3Deng pernicious gas, so as to realize SO2Deng the removing of sour gas, purified gas is through removing mist
Export and discharge from absorption tower afterwards, purified flue enters air flue emission.But desulfuration absorbing tower is in the process of running, is also easy to produce grain
Footpath is " mist " of 10-60 microns, and " mist " not only contains moisture, and it is also dissolved with the sulfuric acid, sulfate, SO of high concentration2、NOX, can inhale
Enter the pollutant such as particulate matter (PM10) and fine particle (PM2.5).If do not properly settled, any " mist " into chimney is actual
It is exactly SO2、NOX, the pollutant emission such as pellet (PM10) and fine particle (PM2.5) is into air.At present, it is electric
Blade in factory's wet process of FGD demister is all the structure being fixedly mounted, and uses the single folded plate type demisting of type more
Device, the separative efficiency of chevron mist eliminator is limited, especially micron order and submicroscopic particle can hardly be trapped, load adaptability
Many drawbacks such as difference also increasingly show.
The industries such as thermal power generation, Ferrous Metallurgy are undoubtedly using flue gas desulfurization technique reduces SO2The effective measures of discharge.But
It is that current people are concerned about that more is the simple desulfurization of system, the preliminary investment of system and operating cost etc., and in desulphurization system
To secondary pollution caused by environment and the optimization of system etc., seldom systematic research after normal operation discharge.Such as wet method
Desulfurization (FGD) absorption tower --- the in line problem of saturated vapor.Although the m of 100-300 ten thousand3/ h flue gases have carried out desulfurization process, desulfurization
SO in flue gas afterwards2, flue dust greatly reduce, but those form huge eye-catching " dense smoke " (demister from the flue gas of power plant emission
Demisting efficiency it is not high, (droplet includes dustiness≤75mg/Nm to the drop for entrainment of escaping3) and in substantial amounts of saturated vapor
Contain SO2Solid granulates and by SO2The SO converted through catalytic process3Sulfuric acid aerosol (100mg/Nm3Left and right) enter air shape
Into the basic condition of secondary pollution.
The influence of climate environment, these " dense smokes " are on the specific date (when ground temperature is relatively low, air pressure is relatively low or in haze
The period of weather) ground can be directly deposited to, form new ground pollution, it has also become prominent atmospheric environment problem.
For the industries such as these thermal power generation, Ferrous Metallurgy under specific weather conditions, inhalable in air is used as flue gas
In sulfuric acid aerosol condensation centre and form haze, reduce visibility of air, particularly sulfuric acid aerosol and flue gas and big
Metal particle in gas is combined, and forms inhalable thing, and these the inhalable murders by poisoning of thing to human body are very strong, pay close attention at present
Emphasis, therefore, system must shut off or be bypassed, or the industry such as thermal power generation, Ferrous Metallurgy must stop production, warp caused by it
Ji is lost and country and social negative effect can not be estimated.
In addition, produce substantial amounts of Thomas slag, electroslag in steel industry production process, wherein because free calcium oxide,
The composition of free magnesium is present, and causes the industries such as cement to be fully used, and uses consumption steel mill discarded object prepared from steel slag
The standby recycling that treatment of wastes with processes of wastes against one another mode can be realized into modulation desulfurization slurry, solves environmental issue.
