Description

Technical Field

[0001] The invention relates to the technical field of dust sludge treatment, in particular to a device for treating iron-containing and zinc-containing dust sludge solid fertilizer in a rotary hearth furnace. Background Art

[0002] Zinc-containing dust mud contains a large amount of valuable metal elements such as zinc and iron, of which zinc accounts for 2% to 10% and iron accounts for 20% to 40%. It has important resource recycling value. In addition, zinc-containing dust sludge contains a large amount of harmful elements such as potassium, sodium, and chlorine. Direct reuse is not conducive to the smooth production of metallurgical kilns. Therefore, it cannot be directly returned to the smelting process and must be removed by a corresponding process. After the dust sludge is discharged after heating reaction reduction, the valuable elements and iron inside it can be recycled. Referring to the Chinese patent, application number: "202210845926.5" "A method and device for treating zinc-containing dust sludge", this patent solves the problem that the amount of tail sludge produced after the existing dust sludge is heated and reduced, and it cannot be effectively utilized as a resource. In the process of dust sludge mixing, since reducing agents, adhesives, etc. need to be added to the inside, the dust sludge entering the mixing bin is prone to agglomeration, which will prolong the time required for material mixing and reduce the operating efficiency of the equipment. For this reason, we propose a solid fertilizer treatment device for iron-containing and zinc-containing dust sludge in a rotary hearth furnace to solve the above problems. Summary of the Invention
