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 volatile matter of lead and zinc non-ferrous smelting slag at high temperature, including a tube furnace / vacuum atmosphere furnace, protective gas, water pump and cooling tower, and one end of the tube furnace / vacuum atmosphere furnace There is a sealing element, and the pipeline with protective gas is connected to the tube furnace / vacuum atmosphere furnace through the sealing element; the other end is connected to the cooling tower through a water pump to form a cooling circuit; the constant temperature section of the tube furnace / vacuum atmosphere furnace is set to be useful In the crucible where the sample is placed, a collector is provided at the connection between one end of the tube furnace / vacuum atmosphere furnace and the cooling circuit. The invention can collect the volatile matter of lead-zinc slag at high temperature relatively completely with high efficiency and without changing material properties; using the volatile matter collected in the invention to study the high-temperature physical properties of lead-zinc slag is more accurate and has more reference value.

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...
