Description

Technical Field

[0001] The utility model relates to the field of chemical purification, in particular to a metal silicon purification device. Background Art

[0002] Silicon is a man-made material. During the manufacturing process of silicon, silicon must be separated from silicon compounds and further purified from the separated silicon. Although silicon is the second most abundant element in the earth's crust, it is composed of a variety of compounds, so it needs to be purified. Commonly used purification methods include smelting, gas phase method, oxidation method, dissolution reduction method, etc.

[0003] The problems existing in the prior art are as follows: Under the prior art, the purification of metallic silicon mostly adopts the dissolution reduction method, which is to dissolve the silicon source material in an appropriate solvent. When the silicon source material is dissolved in an acidic solution, the impurities therein react with the acid in the solvent to produce easily precipitated compounds. However, the filter residue treatment method under the prior art cannot clean the filter residue in time, and the filter residue is easy to adhere to the filter screen after precipitation, which reduces the filtering effect of the filter screen and increases the difficulty of cleaning the filter screen.

[0004] To this end, we propose a metallic silicon purification device to solve the above problems. Utility Model Content
