Description

Technical Field

[0001] The utility model belongs to the technical field of slag treatment, in particular to a harmless treatment device for smelter slag. Background Art

[0002] Slag is a by-product of the blast furnace ironmaking process. During the ironmaking process, iron oxide is reduced to metallic iron at high temperatures, and impurities such as silicon dioxide and aluminum oxide in the iron ore react with lime to form a molten material with silicates and aluminosilicates as the main components. After quenching, it becomes a loose, porous granular material, which is blast furnace slag, referred to as slag. Slag needs to be landfilled, but there are currently the following disadvantages when landfilling slag:

[0003] 1. Slag often contains a large amount of impurities containing water-soluble heavy metal elements. If it is directly landfilled, it will pollute the surface soil, so it needs to be washed. The current slag washing method is generally through immersion, which consumes a large amount of water and is not convenient for the separation of water and slag;

[0004] 2. The density of slag is relatively small, and it generally presents a loose and porous structure. If it is directly landfilled, a larger landfill space is required, and the uncompressed slag is prone to collapse after landfill.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content
