Title:
FLASH FURNACE HAVING SIDE-BLOWN MOLTEN POOL SECTIONS
Document Type and Number:
WIPO Patent Application WO/2017/185857
Kind Code:
A1
Abstract:
A flash furnace having side-blown molten pool sections, comprising a reaction tower (1). At least one molten pool (2) is provided below the reaction tower (1); each molten pool (2) is provided with a side-blown molten pool section having an inner width of less than 3 m; a side-blown arrangement is provided on a side surface of the side-blown molten pool section; a slag discharge port is provided at a tail end of the side-blown molten pool section; the side-blown molten pool section is located between the slag discharge port and the reaction tower (1). The flash furnace further comprises an uptake flue (3) that is in communication with the reaction tower (1) by means of the molten pool (2). By providing a side-blown molten pool section having an inner width of less than 3 m, all portions of a molten pool (2) can be directly affected by side blowing, and a liquid melt environment with good flowability is formed by the molten pool (2), thereby implementing functions such as slag formation, and the settling, stratification, and discharging of slag and metal. In addition, the arrangement of side blowing can also provide a reducing agent for the molten pool (2) to complete the reduction of the remaining metal oxides to be smelted in a slag layer so as to improve the recovery of metal.
