Dust removing device for blast furnace casting house

Abstract

The invention discloses a dust removing device for a blast furnace casting house, which comprises a plurality of side suction hoods arranged on one side of a casting runner, wherein the casting runner is formed by oppositely and vertically arranged support devices; the top ends of the support devices are flush; cover plate components sealing the casting runner are arranged at the top ends of the support devices; and a casting runner smoke trapping channel communicated with an upper part space of the casting runner is arranged between every two adjacent side suction hoods. As smoke produced above the casting runner is confined to a sealing space formed by the cover plate components and the support devices all the time, the dust removing device can efficiently trap and treat the smoke through the side suction hoods and the casting runner smoke trapping channels.

Description

technical field [0001] The present invention relates to the technical field of blast furnaces, and more particularly, to a dedusting device used in blast furnace tapping yards. Background technique [0002] Most of blast furnace casting yards are slope type casting yards. Generally, top suction hoods, side suction hoods and tank hoods are installed in the casting yards to capture smoke and dust. Due to the large difference in elevation, sealing cannot be achieved. The blast furnace produces a large amount of soot during the tapping process. Part of the soot at the tap hole and pot position can be captured, but the soot at the iron ditch is difficult to capture, resulting in the overflow of soot and causing serious damage to the production environment of the blast furnace. Pollution. [0003] At present, dust removal methods such as sealing the cover plate are often used, but the surface damage between the cover plate and the support device supporting the cover plate caused...

Problems solved by technology

[0002] Most of the blast furnace casthouses are slope-type casthouses. Generally, top suction hoods, side suction hoods and tank position hoods are installed in the casthouse to collect smoke and dust. Due to the large difference in elevation, sealing cannot be achieved

The blast furnace produces a large amount of smoke and dust during the tapping process. Part of the smoke and dust at the taphole and the tank can be captured, but it is difficult to capture the smoke and dust at the iron ditch, resulting in the overflow of smoke and dust, causing serious damage to the production environment of the blast furnace. Pollution

[0003] At present, dust removal methods such as sealing cover plates are often used, but due to the surface damage between the cover plate and the support device supporting the cover plate caused by frequent hoisting of the cover plate, the gap between the cover plate and the support device increases. Unable to capture smoke and dust, can not achieve a good dust removal effect
