Title:
SKYFLASH FURNACE
Document Type and Number:
WIPO Patent Application WO/2017/185859
Kind Code:
A1
Abstract:
A skyflash furnace, comprising a reaction tower (1) and a feeding device for feeding materials to the reaction tower (1). A vaporizing chamber (5) is connected to the reaction tower (1). At least one melting pool (2) is provided at a lower portion of the reaction tower. Each melting pool (2) is provided with a side-blowing melting pool section having an inner width less than 3 m. A side-blowing layout is provided at a side of the side-blowing melting pool section. The skyflash furnace further comprises a flue (3) for discharging flue gases generated in a reaction process. The flue (3) is in communication with the reaction tower (1) by means of the melting pool (2). On one hand, the skyflash furnace can generate a high-concentration reducing gas in the vaporizing chamber (5), provide heat required for smelting in space, and guarantee that the reducing reaction of a metal oxidized ore floating and dropping in the reaction tower (1) can be conducted quickly and effectively. On the other hand, by setting the side-blowing melting pool section, positions of the melting pool (2) can be blown completely to supplement heat and provide a reducing agent for the melting pool to complete reduction of the remaining metal oxides to be smelted in the oxidized ore.
