Description

Technical Field

[0001] The utility model relates to the technical field of organic silicon processing, in particular to an iron powder replacement device for organic silicon processing. Background Art

[0002] In the organosilicon industry, during the synthesis of methylchlorosilane monomers, a liquid-solid mixture with flow properties is obtained by wet dust removal, which is organosilicon waste slurry. This waste slurry is then removed by high-temperature distillation, hydrolysis and other means to remove the chlorosilane substances in the slurry to obtain copper-containing waste silicon slag (where the mass fraction of copper can reach up to about 5%).

[0003] At present, by adding acid solution and oxidant to copper-containing waste silicon slag, stirring and reacting, a solid-liquid mixture containing copper ions is obtained, and then iron powder is added for replacement reaction to obtain elemental copper, which can be collected. However, in the process of adding iron powder, it is usually added all at once. If less is added, the reaction will be insufficient, and adding too much will cause waste of raw materials. In addition, iron powder is easy to clog the feed port. After the replacement reaction is completed, the elemental copper needs to be filtered out through a filtration process, and the work efficiency is not high. For this reason, we designed an iron powder replacement device for silicone processing to solve the above problems. Utility Model Content
