Description

Background

Lead is an important chemical element and widely applied to the fields of buildings, lead-acid storage batteries and the like, and meanwhile, lead is a toxic substance, and lead directly discharged into the environment can not only cause harm to the environment, but also influence human health, so that lead recovery is one of important components for sustainable development, and lead recovery and reuse can enable lead to form a production-consumption-regeneration virtuous cycle, and avoid harm to the environment and human health. The lead recovery process generally comprises the steps of reducing compound lead in lead-containing waste materials into metallic lead by using iron powder, then smelting and recovering lead in lead recovery equipment, separating the lead in a liquid form to obtain crude lead, and recovering pure lead after refining. However, when the lead is recovered by the conventional lead recovery process, the lead flows out of a slag outlet of the lead recovery equipment, so that the lead recovery rate is reduced. Meanwhile, because the lead is recovered under the condition of extremely high temperature, the recovery device is prevented from being damaged due to overhigh temperature in order to cool the recovery device.

In addition, exhaust gases such as SO2, NOX, smoke, etc. are generated during the lead recovery process, and if these exhaust gases are directly discharged into the air, not only polluting the environment, but also causing harm to the human health, it is necessary to cool the high-temperature exhaust gases, filter them, and discharge them after filtering layer by layer.
