NLMK Lipetsk, NLMK Group's flagship production site, has embarked upon a large-scale overhaul of its steelmaking capacities, namely BOFs and associated
dedusting equipment in BOF Shop No.2.
There are many kinds of
dedusting technologies and dust collectors [1], most of which focus on wet
dedusting and filter removal technologies, especially on spraying
dedusting [2-4] and filter-bag
dedusting.
After identifying the increased dust levels as the issue, Replogle undertook online research of
dedusting equipment and contacted Ryan Buskey of Polymer Systems Solutions (polymer-ss.com), a manufacturers' representative, who eventually put him in touch with Pelletron Corp., Lancaster, Pa.
The analysis of current state of
dedusting technologies shows that in the most ecologically dangerous industry--thermal power--mainly direct-flow systems are used with some one type of the dust arrester (battery cyclone, wet scrubber or the electric precipitator).
And still another one is "vacuum," which is really
dedusting with a powerful engine that costs hundreds of dollars rather than a plain old rag, which you get for free just by cutting up an old shirt you outgrew in 1982.
Dedusting of the filter cartridges is done using a fully automated microprocessor Pulse Control.
Dedusting technology reportedly leads to a reduction in your scrap percentage, a reduction in material consumption, a better quality product and a cleaner production environment.
FLSmidth will deliver a vertical cement grinding mill with environmentally friendly bag type air filters for
dedusting. This type of mill saves some 40% in power consumption compared to traditional ball mills.
'Strongmaster' is designed specifically for industrial fume extraction that is easy to use with a fan capacity of 3,000m3/hour, a separator and a durable manual dedustable large surface class W3 UPF filter cartridge, which remains in the unit during
dedusting making operator exposure to dust extremely low.
