Abstract

The invention discloses a molybdenum oxide roasting production line. The molybdenum oxide roasting production line comprises a rotary kiln, a heating system, a loading system and a smoke treatment system; a kiln body of the rotary kiln includes a refractory layer, a heat exchange layer and an insulation layer in sequence from inside to outside; the heat exchange layer is a heat exchange wind way surrounded between the refractory layer and the insulation layer; a rotary sealing device is arranged at a charging end of the rotary kiln, and is provided with a fresh wind inlet communicated with the heat exchange wind way; and the heat exchange wind way is communicated with an inner cavity of the rotary kiln. The molybdenum oxide roasting production line realizes zero-coal-consumption energy saving roasting, reduces the production cost, is high in automation degree, reduces the labor intensity, is all-sealed and free of leaking points and fly dust in the production process, comprehensively improves the production environment, and greatly improves the product yield and the material recovery rate.

Description

technical field [0001] The invention belongs to the technical field of producing molybdenum oxide from molybdenum sulfide concentrate, and in particular relates to a molybdenum oxide roasting production line. Background technique [0002] Molybdenum is a rare metal, which is widely used in electrical appliances, especially in the production of special steel. When smelting alloy steel, adding an appropriate amount of molybdenum element can make the steel alloy obtain many excellent physical properties, so that molybdenum element is widely used in many steel materials. [0003] At present, more than 90% of the molybdenum sulfide concentrates used at home and abroad must first be desulfurized into molybdenum oxide by roasting. Molybdenum reacts with ammonia water to obtain ammonium molybdate, ammonium molybdate is decomposed to obtain high-purity molybdenum trioxide, and hydrogen reduction is used to obtain high-purity molybdenum dioxide, and hydrogen reduction is continued to...
