Method for prolonging ring forming period in dezincification rotary kiln
The invention belongs to the technical field of dezincification rotary kilns, and particularly relates to a method for prolonging the ring forming period in a dezincification rotary kiln. The total content of total iron, SiO2 and CaO in the zinc-containing dust and mud mixture is controlled within 50% of the total mass of the zinc-containing dust and mud mixture, and the mass ratio of the total iron to the SiO2 to the CaO is (3-4.8): (1-1.5): 1; and controlling the standard deviation of total iron, the standard deviation of SiO2 and the standard deviation of CaO in the zinc-containing dust and mud mixture to be within a set threshold value. By adopting the method disclosed by the invention, a large amount of fayalite and hematite can be prevented from being generated when the zinc-containing dust and mud mixture is treated, so that ring formation in the rotary kiln is prevented, the ring formation period of the dezincification rotary kiln is further prolonged, the ring formation period of the dezincification rotary kiln for treating the zinc-containing dust and mud mixture is prolonged to 11-12 months from 3-6 months, and the yield of the dezincification rotary kiln is improved. The influence on production is reduced, the operation rate is improved, and meanwhile the production cost of the rotary kiln is reduced.
本发明属于脱锌回转窑技术领域，具体涉及一种延长脱锌回转窑窑内结圈周期的方法。将含锌尘泥混合料中总铁、SiO2及CaO的总含量控制在含锌尘泥混合料的总质量的50％以内，总铁、SiO2及CaO的质量比为3‑4.8：1‑1.5：1；控制含锌尘泥混合料中总铁的标准偏差、SiO2的标准偏差以及CaO的标准偏差均在设定的阈值内。采用本发明所述方法可以防止在处理含锌尘泥混合料时生成大量的铁橄榄石和钙铁橄榄石，从而防止导致回转窑内结圈的产生，进一步延长脱锌回转窑的结圈周期，使处理含锌尘泥混合料的脱锌回转窑结圈周期从3‑6月延长到了11‑12月，减少了对生产的影响并提高了作业率，同时降低了回转窑生产成本。
