Metalloinvest is implementing a large-scale investment project to reconstruct the gas purification systems at Lebedinsky GOK’s pelletising unit. Scrubbers in the aspiration system have been replaced with electric filters – devices in which gases are purified with the help of an electric field. Metalloinvest favours this method of dust collection in the production process as the most effective.
The first such electric filter was built on the drying path of Pellet Plant #4 in December last year. Currently, construction of an electric filter for flue gas cleaning of drying drums and ball mills at the charge preparation section is nearing completion. Supports and gas ducts have been mounted, thermal insulation is being installed, and electrical installation work is being finalised. The new module is expected to be operational in December.
Alexander Vatutin, Head of the Department for Prospective Development at Lebedinsky GOK’s pelletising unit, stated: “The effectiveness of gas purification has reached 99%. The dust formed in the pellet roasting process settles on the electrodes of the system while purified air enters the atmosphere.”
In the middle of the year, another electric filter will be built on the second path of Pellet Plant #3. The foundation for the facility has already been laid. |
