Abstract

The invention discloses a pyrotechnic lead smelting device, comprising: an oxidation unit, the oxidation unit is provided with a first slag outlet, and the first slag outlet is connected with a slag chute; a reduction unit is provided with a first slag feeder The first slag inlet is connected with a slag chute; the soot unit, the soot unit includes a soot treatment device, and the soot treatment device is connected with a first smoke outlet pipe and a second smoke outlet pipe, the first smoke outlet pipe and the oxidation unit Communication, the second smoke outlet pipe is in communication with the reduction unit. The soot in the oxidation unit and the reduction unit is collected and then granulated by the provided soot unit, and the granulated soot is directly added to the reduction unit, so that the product quality and the stability of the device are improved.

Description

technical field [0001] The invention relates to the technical field of a pyrotechnic lead smelting device and process, in particular to a pyrotechnic lead smelting device and a lead smelting process. Background technique [0002] Fire refining of crude lead refers to the process of removing impurities in smelting crude lead in stages and producing refined lead, which is an important part of the fire refining process. The crude lead produced by lead smelting also contains impurities such as bismuth, tin, arsenic, antimony, zinc, and sulfur, as well as precious metals such as gold and silver, and rare metals such as selenium and tellurium. The total amount of impurities is about 1%-4%. Therefore, the purpose of refining is not only to remove impurities that have adverse effects on the properties of lead, so that refined lead meets the requirements of users, but also to comprehensively recover valuable metals in crude lead. [0003] There are two methods for crude lead refini...
