The Lead-Tin vacuum distillation unit (Pb Sn Sb VDF) separates Tin from lead alloy, a byproduct of lead smelting. It uses varying boiling points of Tin, Antimony, and Lead under vacuum to remove impurities.
Operating under the vacuum, the Sn VDF creates distinct boiling points for different metals. The vapors of lead and tin condense at different locations, forming liquid lead and tin.
The VDF relies on electricity for heat and operates without emitting gases, making it environmentally preferable. It includes a method for collecting arsenic at low concentrations (As≤1%). If arsenic content exceeds a certain threshold (As≥2%), it must be removed before furnace use.
When it's under vacuum, the Pb-Sn-Sb VDF makes different metals boil at different points. Inside the Pb-Sn-Sb VDF's graphite tray, the vapors of lead and tin move to different spots, and turn into liquid lead and tin.
The Pb-Sn-Sb VDF uses electricity for heat, and it doesn't let out any gases while working, which makes it better for the environment. It also has a way to collect arsenic when there's not too much of it(As≤1%). If there's too much arsenic(As≥2%), it needs to be removed before using the furnace.
