Application and development tendency of dry dust removal technology in the nonferrous-metals industry of China

With the increasingly strict environmental regulations, atmospheric environmental problems have become the focus of national attention. In this paper, the principle, advantages and disadvantages of the electric dust removal method and bag-type dust removal method in the domestic non-ferrous smelting industry are detailed stated, and the new dry dust removal method developed in other fields in recent years is briefly elaborated. Through contrast and analysis, the new dry dust removal technology with its more efficient dust removal efficiency, more excellent performance characteristics, will be widely used in the future smelting industry flue gas dust purification, and to become more practical technology.
