Abstract

The invention discloses an aluminum ash recovery device which comprises a flat belt conveyor, a jaw crusher, an aluminum ash conveyor, a pulverizer, a gravity dust collector, a cyclone separator, a material lifter, a calcium aluminate roasting furnace, a roasted material conveyor and a calcium aluminate finished product warehouse. The invention further discloses a recovery process which comprises the following steps: (1) conveying the aluminum ash into the jaw crusher by the flat belt conveyor, and crushing; (2) conveying the aluminum ash into the pulverizer by the aluminum ash conveyor, pulverizing and sieving; (3) sequentially passing through the gravity dust collector and the cyclone separator; (4) adding the aluminum-containing slag and limestone into the calcium aluminate roasting furnace through the material lifter, and roasting; and (5) conveying the roasted material into the calcium aluminate finished product warehouse through the roasted material conveyor, and completing recovery of the aluminum in the aluminum ash. According to the method, aluminum particles in the aluminum ash are recycled, carbides and nitrides of aluminum are removed, chlorides and fluorides in the aluminum ash are removed, and the aluminum ash is recycled and used for aluminum smelting, so that the whole aluminum industry and secondary aluminum production are environmentally friendly, and benefits are brought to human beings.

Description

technical field [0001] The invention relates to the technical field of resource utilization, in particular to an aluminum ash recovery device and a recovery process thereof. Background technique [0002] Metal aluminum is a metal with low density, high specific rigidity, high specific strength, strong oxidation resistance, good electrical and thermal conductivity, and is widely used in aerospace, weaponry, electric communication, transportation, electronic technology equipment, chemical machinery and Construction and other industries occupy an important position in the construction of the national economy. [0003] China is the world's largest producer and consumer of aluminum metal, with a production capacity of 60 million tons per year and an actual production capacity of 36-45 million tons per year. At the same time, China is the world's largest producer of recycled aluminum. China has abundant bauxite resources, but it cannot meet the needs of domestic rapid economic d...
