Description
Fume produced in sintering
process enters desulfurize tower through stack flue in the tower,
fume firstly take reaction of foam sucking with Ca(OH)2 density
liquid in the tower, and then react with spraying serous fluid
atomized with multi-layer rotary spraying to produce sulfurous acid
Ca for implement dual converse foam sucking technology which
combine foaming sucking technology with spraying atomized suck
technology. Fume which is produced in sintering process, and go
through sulfuration in the
tower, is discharged into atmosphere from newly setup chimney after
water-mist is removed from it by demist device. sulfurous acid Ca
slurry produced by desulfurater reacting with fume is transferred
by liquid discharging pipeline to oxidized system for implementing
oxidization out of the tower.
A〠To
change oxidized in tower into oxidized outside of the tower
B〠To adopt foam sucking technology and spraying
atomized technology
C〠7 patent technologies
2. Technology
Characteristics
1)
Bigger desulfurization capacity, higher desulfurization efficiency,
and adapting to lime, limestone, dedusting for line
kiln
2)
Adapting to wider density scope of
fume sulfur dioxide, higher
adaptability.
3)
Less equipment invested,
comparatively lower investment
cost
4)Lower
ratio between gas and liquid, the power for the cycling pump in the
desulfurization tower is largely reduced to save
energy.
5)Gesso produced after desulfurized
is transferred to cement plant nearby, brick plant or groundsill
treatment engineering for synthesis utilization, without secondary
pollution problem.
6)
Convenient operation, lower
failure ratio
3. Technical guarantee
value
