The Lead-Tin (Pb-Sn) vacuum distillation unit, also known as the Lead-Tin-Antimony metal vacuum distiller unit (Pb-Sn-Sb VDU) and lead-tin alloy separating vacuum distillation furnace (Sn VDF), as well as the tin vacuum distillation furnace (Sn VDF), is designed to extract Tin (Sn) from lead alloy, the byproduct from lead smelting. This process involves utilizing the different boiling points of Sn, Sb, and Pb under varying vacuum conditions to effectively remove impurities.
Under vacuum conditions, the Pb-Sn-Sb VDF exhibits varying boiling points for different metals. Within the Pb-Sn-Sb VDF's graphite tray, lead and tin vapors migrate to different locations, where they undergo condensation and are collected as liquid lead and tin.
The Pb-Sn-Sb VDF uses electricity as a clean heat source. During vacuum distillation, there is no emission of off-gases, distinguishing it from conventional pyro-metallurgy equipment. The lead-tin-antimony vacuum distillation furnace (Pb-Sn-Sb VDF) is an environmentally friendly metallurgical equipment. Additionally, an arsenic (As) collection device is a standardized sub-assembly for the Pb-Sn-Sb VDF, effectively capturing As when its content is ≤1%. (If the As content exceeds 2%, pre-removal is required.)
