铜火法冶金典型工艺单位产品排气量的比较分析

Comparative Analysis of Exhaust Rate of Unit Production of Typical Copper Pyrometallurgy

采用闪速熔炼+闪速吹炼、闪速熔炼+PS转炉吹炼、熔池熔炼+PS转炉吹炼这3种典型工艺的铜冶炼企业主要大气污染物排放环节的单位产品排气量均满足《铜镍钴工业污染物排放标准》中单位产品基准排气量的要求,按照单位产品废气排放量由小到大依次排序为闪速熔炼+闪速吹炼工艺、闪速熔炼+PS转炉吹炼工艺和熔池熔炼+PS转炉吹炼工艺。对各主要大气污染源排气量的对比分析结果表明,闪速熔炼、闪速吹炼具有环保、节能的优点,配合其生产能力大、工艺先进的特征,有利于现有和新建铜冶炼企业在扩大规模的同时还能满足日益严格的环保要求。

The exhaust rate of unit product of atmospheric contaminant from three typical copper pyrometallurgy processes, i. e. , Flash Smelting＋Flash Converting （FS＋FC）, Flash Smelting＋PS Converting （FS ＋PSC）, and Molten Bath Smelting＋PS Converting （MBS＋PSC）, can satisfy the benchmark requirement of ＂Emission Standard of Pollutants for Copper, Nickel, Cobalt Industry＂. The sequence in ascending order of the exhaust rate of unit product is FS＋FC, FS＋PSC, artd MBS＋PSC. The comparative analysis results of the exhaust rate of main atmospheric pollutant show that FS and FC process have the advantages including environmental protection, energy conserving, big production capacity, and advanced technology in copper pyrometallurgy. The FS and FC technology can be of great benefit for copper smelting corpora- tions existing or newly-built to expand the scale and satisfy severe environmental criteria.
