Description
Technical field
It the utility model is related to by removing high-fluorine chlorine secondary zinc oxide flue dust impurity recycling technical field, more particularly
It is related to the equipment of a kind of de- high-fluorine chlorine secondary zinc oxide flue dust and the concentration of valuable metals zinc that cleans.
Background technology
Most of Pb-Zn deposits raw material is all Pb-Zn deposits symbiosis, and being extremely difficult to lead zinc by diffeential floatation is kept completely separate.Lead
It is that zinc is enriched in slag that zinc ore, which is smelted, then handles clinker, output zinc oxide or secondary zinc oxide with fuming furnace.It is in addition, wet
The leached mud and poor zinc oxide ore of method zine-smelting plant output obtain zinc oxide or secondary zinc oxide by rotary kiln fuming.Secondary oxidation
The main component of zinc is ZnO, and simply grade is 45%~65%.So-called " secondary " refers to grade time, in China Guangxi, expensive
The local yield in state, Yunnan, Hunan etc. is larger, mainly utilizes caused Water Quenching Slag and hydrometallurgy during pyrometallurgical smelting zinc
Caused zinc leaching residue and other solid waste containing zinc carry out recovery secondary zinc oxide by rotary kiln baking during zinc,
Secondary zinc oxide purposes is mainly processed further electrolytic zinc or zinc oxide.
About 4/5ths produced at present in the total output of world's essence zinc by wet process smelting technique, i.e. roasting-leaching-net
Change-electrodeposition.With industrial rapid development, the shortage increasingly of mineral resources, it is miscellaneous that zinc concentrate is produced in current domestic mining industry circle
Matter content more and more higher, higher requirement is proposed to the adaptability of zinc abstraction system.In recent years, due in raw material fluorine, chlorine contain
The rising of amount, comprehensive utilization of resources, which maximizes, progressively implements more strict with environmental requirement, many large-scale systems of zinc hydrometallurgy factory
Fluorine, level of chlorine are in rising trend in system.And harm of the presence of fluorine chlorine to wet method system equipment is quite big.
First, the presence of fluorine, chlorine can produce serious harm to equipment, and the influence to mixer is mainly reflected in paddle
On, for wet zinc-making system mixer using extensively, most of paddle material is stainless steel, the rise of fluorine chlorine ion concentration, makes stirring
The service life of machine paddle shortens.Pump is the power that solution conveys in system, and stainless steel pump has good corrosion resistance because of it
And it is used widely.The rise of fluorine chlorine ion concentration in solution, to parts such as the impeller of pump, pump case, pump cover, axle, sealings
Corrosion aggravation, add the consumption of pump.Intercrystalline corrosion, pitting corrosion, stress corrosion, corrosion caused by the medium of fluorine-containing chlorine
The parts that fatigue, cavitation damage, turbulent flow corrosion cause impeller, impeller nut, axle sleeve of pump etc. to be in contact with medium are corroded
Dissolving, it is especially the most prominent with the corrosion of impeller.The leakage of pump can be also caused simultaneously, make the burn into of pump bearing damage and screw rod

Agent can be eased, and after chlorine ion concentration is more than 500mg/L, separates out zinc quality and be severely impacted, and be difficult control
System, while positive plate corrosion rate is substantially accelerated, and when chlorine ion concentration is after 800mg/L, substantially there is chlorine precipitation on anode,
Cause operating environment severe exacerbation.Meanwhile chlorion reacts in anodic oxidation into after chlorate with anode lead, increase solution contains
Lead, the rank for separating out zinc is reduced, shorten anode life.Therefore the chlorine in zinc sulphate electrolyte is contained both at home and abroad and requires to be less than
200mg/L。
