Abstract

The invention provides a zinc-containing blast furnace gas ash smelting device and smelting method, and belongs to the technical field of gas ash smelting methods. The smelting device comprises a smelting furnace, a feeding mechanism, a discharging mechanism and a monitoring mechanism, wherein the smelting furnace is long-strip-shaped, the lower part of the smelting furnace is buried under the ground, an included angle is formed between the bottom face of the smelting furnace and the horizontal plane, the smelting furnace smelts zinc-containing gas ash and produces molten iron and a zinc oxidecrude product, the feeding mechanism is used for conveying blast furnace gas ash dry balls into the smelting furnace, the discharging mechanism is used for receiving the molten iron and liquid slag output from the smelting furnace, and the monitoring mechanism is used for monitoring the temperature in the smelting furnace and a material reaction process. Compared with blast furnace smelting, thesmelting method for smelting the gas ash is high in reaction speed and constant in temperature. The zinc-containing blast furnace gas ash smelting device and smelting method have the technical effectsthat the long-strip-shaped smelting furnace can be used for smelting the zinc-containing gas ash, and the reaction is stable and rapid in the smelting process.

Description

technical field [0001] The invention belongs to the technical field of gas ash smelting methods, and more specifically relates to a zinc-containing blast furnace gas ash smelting device and a smelting method. Background technique [0002] At present, the dust particles discharged together with the blast furnace gas during the blast furnace smelting process are collected by gravity dust collector and bag filter to form bag ash, which is often called gas ash. The carbon content of gas ash is as high as 30% to 50%. The content is low, 15% to 30%, and the content of zinc and sodium is relatively high. Elements such as zinc and sodium are harmful to the blast furnace, and generally cannot be directly used as sintering ingredients. [0003] In addition, there are other dust removal dust in the steel plant system, such as: dust removal dust from coking coal yard, dust removal dust from coal and coke belt corridor, dust removal dust from CDQ system, these dust removal dusts are char...
