Description

Technical Field

[0001] The utility model relates to the technical field of refining furnaces, in particular to a refining furnace for fly ash ionization reduction products. Background Art

[0002] Fly ash is a volcanic ash material, which comes from inorganic components in coal. The inorganic components in coal are mainly clay minerals, and there are also small amounts of pyrite, calcite, quartz and other minerals. Therefore, the chemical composition of fly ash is mainly silicon dioxide and aluminum oxide, and other components are iron oxide, calcium oxide, magnesium oxide, potassium chloride, sodium oxide, sulfur trioxide and unburned organic matter. Fly ash obtains aluminum, silicon and iron by ionization.

[0003] Fly ash contains about 8% unburned carbon. According to rough calculations, the carbon slag in the electrolytic cell and the unburned carbon in the fly ash can just reduce aluminum, silicon and iron. According to the different specifications of aluminum silicon or aluminum silicon iron alloy produced, the difference in aluminum silicon and iron content in the fly ash can be considered to adjust the addition ratio of fly ash and alumina powder. If aluminum silicon alloy is produced, the iron content may be high, and iron removal agent (borax flux, manganese chloride solvent) can be used for iron removal. If aluminum silicon iron alloy is produced, iron removal is not required. Other metal elements can be removed by high-temperature burning or adding refining agents and slag removal agents. The reaction equation in the electrolytic cell is:

[0004] SiO2+2C→2CO+Si(reduction)

[0005] 3SiO+4Al→2Al2O3+3Si(reduction)

[0006] Al 2O3+3C→3CO+2Al (electrolysis)

[0007] Fe2O3+3C→3CO+2Fe(reduction)

[0008] The main element yields during the electrolytic reduction of fly ash: If the fly ash contains 50% silicon dioxide, 27% aluminum oxide, and 8% iron oxide, 1000kg of fly ash can theoretically produce 233kg of elemental silicon, 143kg of metallic aluminum, and 56kg of metallic iron. In order to remove impurities, the obtained metals need to be refined for elemental silicon, metallic aluminum, or metallic iron. Refining requires the use of a refining furnace, which is a smelting equipment in the hot processing industry and is mostly used for the final deoxidation and alloying of molten steel in ferrous metallurgy.
