丹霞冶炼厂沸腾焙烧制酸改造综述

Upgrading of Fluosolids Roasting and Acid Making System in Danxia Smelter

丹霞冶炼厂原有焙烧、制酸系统工艺流程存在缺陷,设备陈旧,无法保证新建10万吨电锌厂的焙砂需求量,满足不了日益严格的安全环保要求。通过对该系统的技术改造,改造后的设备成熟、可靠、节能,注重了循环经济,加强了环境保护,并且提供了水的循环利用,减少废水排放,力求再生使用。

Since the original roasting and acid making system in Danxia Smelter is old and has defects in process flow,it cannot meet the calcining demand of the newly-built 100 000 t/a zinc plant and the increasingly strict requirement on safety and environment.After careful assessment,technological transformation is carried out to the system.Now the equipment in the system is mature,reliable and energy-saving,which makes possible the friendly environment and water recycle.
