But method.
Background technology
In a variety of wet desulfurizing process, there is the tower spray absorption tower of a kind of wet type desulfurizing.The master of spray absorption tower
Operation principle is wanted, is the spraying layer that desulfurization slurry is transported to several circulating pumps desulfurizing tower middle and upper part, the general cloth of spraying layer
If being set to dried layer, every layer is arranged several nozzles, and desulfurization slurry forms atomization slurry spray after the atomizing of nozzle sprays
Area.When flue gas is through spray region, flue gas and slurry liquid contacts, the SO in flue gas2Slurries absorption is desulfurized Deng gas, absorbs SO2Deng
Slurries after gas are fallen into the desulfurization slurry pond of desulfurization tower bottom, then by circulating pump are delivered to spraying layer again, during meeting
Fresh desulfurization slurry is continuously added, discharge part desulfurization slurry carries out gypsum preparation.Desulfurization slurry in desulfurizing tower is spraying
During, the droplet after part atomization can be carried by flue gas, and the main component contained in droplet is that lime stone etc. is de-
The materials such as the calcium sulfate that sulphur agent generates with reactions such as the sulfur dioxide in flue gas, after these droplets enter follow-up flue, meeting
Corrosion and clog downstream equipment, such as flue gas heat-exchange unit, when being discharged from throat, flue-gas temperature gradually reduces, full in flue gas

Demister is the device for trapping the drop carried secretly in flue gas, and its material mainly includes high polymer material and stainless
The major class of steel two.According to the geometry of demister blade, demister can be divided into two kinds of shapes of deflection plate and corrugated plating, according to except
The arrangement form of day with fog, demister are often divided into tubular type, flat arrangement and three kinds of forms of ridge type.Demister is typically located at de-
Sulphur tower top end, also there are a small number of designs that demister is arranged in into desulfurizing tower and export in net flue.
Demister relies primarily on gravity and inertial impaction effect, and the flue gas containing droplet passes through demisting with certain speed
During the bending channel of device, flue gas changes direction rapidly, and droplet strikes demister in the presence of inertia and centrifugal force
On, so as to be captured down.To strengthen the defogging effect of demister, typically by calculating flue gas flow rate, suitable demisting is selected
Device arrangement form, by optimizing the arrangement of demister, such as appropriate increasing demister bottom and the spacing of top spraying layer, carry
Flow field uniformity in high demister, reducing local velocity transfinites, and can strengthen the defogging effect of demister, reduce taking for slurries
Band, mitigate " gypsum rain " phenomenon, but the demisting of wet desulfurization flue gas can not be properly completed in existing technology, and can not solve
The problem of certainly demister blocks in use.
