Problems solved by technology

The applicant repeated the experiment and found that this method requires a large amount of reactive substances, but only a small part of the volatile substances can be collected, less than 10%.
Even if the experimenter collects the condensed substances from the walls of the furnace tubes and ducts, he will find that the collected amount is not complete, and more substances escape through the gas or the reaction disappears.

Abstract

The invention discloses a device and method for collecting lead and zinc nonferrous metallurgic slag volatile matters at high temperature. The device comprises a tube furnace / vacuum atmosphere furnace, a protective gas, a water suction pump and a cooling tower, wherein a seal element is arranged at one end of the tube furnace / vacuum atmosphere furnace; a protective gas introduced pipeline is connected with the tube furnace / vacuum atmosphere furnace through the seal element; the other end of the tube furnace / vacuum atmosphere furnace forms a cooling loop with the cooling tower through the watersuction pipe; the constant temperature section of the tube furnace / vacuum atmosphere furnace is provided with a crucible for sample placement; and a collector is arranged at the joint of one end of the tube furnace / vacuum atmosphere furnace and the cooling loop. The device can be used for collecting lead and zinc slag volatile matters at high temperature efficiently and relatively completely without changing substance properties; and the high temperature property of lead and zinc slag can be accurately studied and has better reference value by adopting the volatile substances collected by thedevice.

Description

technical field [0001] The invention belongs to the technical field of solidification and collection of volatile substances in the process of pyrometallurgy of lead and zinc, and specifically relates to a device and method for collecting volatile substances of lead and zinc nonferrous smelting slag at high temperature. Background technique [0002] Non-ferrous metallurgical slags containing lead and zinc are volatile slags. During the smelting process, lead, zinc metals and their oxides will continue to escape; the escape of these substances will lead to changes in the properties of the slag, and what kind of changes have taken place in the properties, and what substances in the slag cause the changes , require more research work. Once the relationship between volatilization-composition-substance-property changes can be fully analyzed, it will be of great significance to the smooth progress of the pyrometallurgy process and its process optimization. [0003] It is a more e...
