根据工厂生产实践材料,研究了锌精矿富氧沸腾焙烧中的几个技术问题,以及富氧焙烧中的电耗和生产成本问题,指出了在铅锌联合企业中,富氧焙烧能显著增产,烟气中SO_2浓度能大幅度提高、节约能耗,降低成本,还可以合并回收低浓度铅烧结SO_2,有利于环保。 According to the factory production practice material, several technical problems in oxygen enrichment roasting of zinc concentrate, as well as the power consumption and production cost in oxygen-rich roasting are studied. It is pointed out that in the lead-zinc joint venture, , The SO 2 concentration in the flue gas can be greatly improved, the energy consumption is saved, the cost is reduced, and the low-concentration lead sinter SO 2 can also be combined and recovered, which is good for the environment protection.
