Background technology
Wet scrubber washs the purpose that dust laden air reaches dedusting using water.Wet three efficient duster is to use two-stage
The organic combination that cyclone dust collection and one-level water gather dust, because structurally simple, economical practical, operation is simple, maintenance workload is small,
Floor space is small, to the low advantage of water quality requirement, be widely used in ore deposit, metallurgy, cement, chemical industry, the non-hydrophobic of industry such as papermaking
The treatment of gathering dust of property dusty gas.
Clinker is burnt till in course of conveying in alumina industry, dirt containing ground caustic diffuses everywhere, be to realize that environment protection standard is arranged
The difficult point put.In addition, in wet zinc-making system, essential meeting produces a big chunk acid leaching residue and lead skim, this
Using pyrogenic attack to reclaim its valuable metal lead, zinc, germanium, silver etc., wherein acid leaching residue carries out middle leaching, acidleach to part slag by calcining
Output afterwards；, by zinc oxide fumes by produced after sulphuric leaching, two slags are before carrying out pyrogenic process and reclaiming valuable metal for lead skim, it is necessary to
By pressure-filteration drying operation, to ensure the moisture of slag and improve the rate of recovery of valuable metal.In drying process, must not
The substantial amounts of SO of generation that can lack2Gas and dust, spray-absorption abjection is carried out using Wet three efficient duster to it, to reach
99% abjection effect, then ensure that its internal negative pressure seems increasingly important.But traditional Wet three efficient duster, actual abjection
Effect is not good, it is impossible to reach 99% extrusion rate, and only 95% or so, it very big one is primarily due to akaline liquid spray
After collection, dust is caught and is slurried into slurries, but dust-laden slurries are when flowing downwardly to cone and being flowed out through the gravity balance valve of its underpart,
Due to being continuous production, and amount is larger, then the dust-laden slurries for being produced can not be stored, it is necessary to continuous discharge, then cause gravitational equilibrium
Valve is chronically at open state, it is impossible to play sealing function, also it cannot be guaranteed that its negative pressure, so as to produce " gas leakage " phenomenon, causes
SO2Gas and dust leak, and cause SO2The spray extrusion rate of gas and dust is substantially reduced.Due to wet type triple effect dedusting system
System is wide in field of metallurgy application, and this technology it is critical only that spray system and drainage, and difficult point is mainly
It is that, in drainage, to solve above-mentioned situation, researching and developing a kind of blowdown apparatus of negative pressure in effective guarantee Wet three efficient duster is
It is very necessary.
