含铅烟尘被循环细粒还(厂元)后直接进入悬浮烧结炉。几乎所有冶炼过程,无论黑色还是有色冶炼,都是在炉料中一种或多种反应物挥发的温度下进行的。这些挥发物通常被烟气机械地带走。在大多数工业中,烟气必须净化以免污染厂区。 Lead dust is recycled fine particles (factory yuan) directly into the suspension sintering furnace. Almost all smelting processes, whether black or non-ferrous smelting, are carried out at a temperature at which one or more reactants volatilize in the charge. These volatiles are usually mechanically removed by the flue gas. In most industries, flue gas must be purified to avoid contamination of the plant site.
