摘要:冶炼烟气制酸是硫酸工艺的主要组成部分，用冶炼烟气制酸，既保护环境，又是资源的综合利用，在经济和社会效益上具有较大的优势。锌冶炼中的烟气制酸是不可或缺的流程，不仅可以减少尾矿浪费、还可以减少污染气体的排放，增加企业效益。

   本设计主要是根据锌矿冶炼后烟气通过设备净化——干吸——转化，两转两吸从而得到产品的主要流程线路，主要设备绘制以及平面图布置，涉及基本的数据计算。针对锌工艺流程中 ，烟气制酸年产20万吨车间设计。希望能够简易的展现锌冶炼流程中烟气制酸的流程。

ABSTRACT:Smelting gas in acid is the main component of sulfuric acid process, with smelting gas system acid, protecting the environment, and both the comprehensive utilization of the economic and social benefits, with greater advantage. The flue gas zinc smelting in acid is indispensable process, not only can reduce tailings waste, still can reduce pollution gas emissions and increase enterprise benefit.

  This is designed according to the constitution by equipment after purifying smoke smelting transformation, dry suck - - two turning two suck and get the main flow line, product plan layout drawing and main equipments, involving basic data calculation. for zinc process, flue gas system acid yearly produces 20 tons of workshop design Hope to simple show zinc smelting process the flow of gas in acid

Keywords: Flue gas system acid; purification; drying and absorption;transformation
