Abstract

The invention relates to a blast furnace gravitational dust and ash removal device. The blast furnace gravitational dust and ash removal device is characterized by comprising a gas ash removal stirrer, an electric telescopic device, a blast furnace casting house dust removal system pipeline, an electric telescopic device left-and-right sliding rail, a tank car, a steel structure platform, cone section tuning fork material level switches and a star type ash discharge valve; and the gas ash removal stirrer and the left-and-right sliding rail are arranged on the steel structure platform, the startype ash discharge valve is arranged below the cone section tuning fork material level switches, the blast furnace casting house dust removal system pipeline is arranged on the electric telescopic device, and the electric telescopic device is located below the steel structure platform. According to the scheme, the problem that environmental pollution is easily generated by gravitational dust removal and ash discharge and the problem about use of fly ash are solved, and energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to a blast furnace gravity dust removal device, which belongs to the technical field of blast furnace slag treatment. Background technique [0002] Compared with the blast furnace, the gravity dust removal is a dust removal, mainly because during the smelting process of the blast furnace, the coke combustion provides heat for the blast furnace smelting, and realizes the oxidation and reduction of the sintered ore. After the coke is burned, the blast furnace gas is formed, and the blast furnace gas is drawn out of the blast furnace through the riser The body, metal dust and other mixtures pass through the gravity precipitation of the gravity dust removal tower to form a dust removal process. The gas after the first dust removal process is purified, and then further purified by dry dust removal or wet dust removal. The purified gas is usually used TRT turbine The power generation finally enters the gas pipeline network; the dust dus...
