Description
Technical field
The invention belongs to Ferrous Metallurgy sintering smoke wet method sulphur technical field, particularly be used for the preceding cooling device of smoke-gas wet desulfurization.
Background technology
Cooling device before traditional sintering smoke wet method sulphur as shown in Figure 1 and Figure 2.
Cooling device shown in Figure 1 comprises one-level cooling system 12, the waste liquid outlet 13 of rinse-system 11, the barrel front end of barrel front end, the secondary cooling system 14 and the cooling device base plate 15 of cylinder back-end.The weakness of this kind cooling device is that the waste liquid that one-level cooling (lime stone slurry) and secondary cooling (fresh water (FW)) are produced can not be discharged effectively, and particularly secondary cools off the influence that the waste liquid that is produced still is subjected to flue gas resistance, is difficult to reflux.Through long-play, on the base plate of cooling device, hoard a large amount of gypsum, stop up outlet.For example a certain purpose cooling device is because of the gypsum overheap, the cooling device base plate cracking that is crushed out of shape that can't bear the heavy load, and corrosion-resistant lining material Hastelloy C-276 lost efficacy simultaneously, brought about great losses to project.
Cooling device shown in Figure 2 comprises the rinse-system 21 of barrel front end, the one-level cooling system 22 of barrel front end, secondary cooling system 24, cooling device base plate 25 and the secondary cooling outlet 26 that one-level is cooled off outlet 23, cylinder back-end.This kind cooling device has solved hoards a large amount of gypsum problems on base plate, but too loaded down with trivial details, and two place's outlets need not be set.
Cooling device illustrated in figures 1 and 2 all is provided with the rinse- system 11,21 of barrel front end, and the one- level cooling system 12,22 of barrel front end all is to absorb cooling with alkali lye (being generally lime stone slurry) simultaneously.Because it is very high to enter the flue-gas temperature of barrel front end, on average is about 120 ℃～150 ℃.Under such high temperature, the lime stone slurry fouling that is cured very soon, and then stop up the one-level cooling jet, cause the one-level cooling failure.Only depending on secondary cooling flue-gas temperature to be reduced to below 70 ℃ (be higher than 70 ℃ can scaling loss absorption tower internals), need use a large amount of fresh water (FW)s, so promptly waste energy and can produce a large amount of waste water, is to be uneconomical not environmental protection again.
Therefore, be necessary that developing a kind of smoke-gas wet desulfurization cooling device in the present technique field solves the problems referred to above: the one, the cooling device base plate must not be hoarded a large amount of gypsum; The 2nd, the one-level cooling system must not stop up inefficacy, guarantees through I and II cooling back flue-gas temperature to be reduced to below 70 ℃, reduces operating cost simultaneously.
