This invention relates to the field of non-ferrous metal metallurgy, and particularly to a zirconium tetrachloride purification system and method. The zirconium tetrachloride purification system includes a purification furnace; a vacuum collection tank connected to the furnace via a first pipeline, on which an exhaust valve is installed, and a discharge port at the bottom of the vacuum collection tank; a circulating cooling water system connected to the vacuum collection tank; a filter connected to the vacuum collection tank via a second pipeline, on which a first pneumatic valve is installed; a tail gas spray tower connected to the filter via a third pipeline; and a control system electrically connected to the exhaust valve and the first pneumatic valve. This zirconium tetrachloride purification system and method solves the problems of low control accuracy and inherent dangers in existing zirconium tetrachloride purification methods.

The application relates to a composite halide solid electrolyte and a preparation method thereof, and belongs to the technical field of solid electrolytes. The preparation method comprises the following steps: S1, under a protective atmosphere, uniformly ball-milling a lithium source, a zirconium source, an M source and an ammonium halide, and then sintering, and obtaining a nitrogen-rich halide through cooling; S2, under a protective atmosphere, transferring the nitrogen-rich halide into a reaction chamber of a fluidized bed vapor deposition reactor, then circulating and sequentially introducing a metal / metalloid source compound, water and a lithium source into the reaction chamber to carry out deposition, forming a conductive interface layer on the surface of the nitrogen-rich halide, and obtaining a composite halide; and S3, circulating and sequentially introducing an aluminum source and water into the reaction chamber to carry out deposition, forming a protective layer on the surface of the composite halide, and obtaining a composite halide solid electrolyte. The material can effectively adapt to cyclic stress, avoid cracking and peeling, and ensure the durability and reliability of the protection effect of the battery in the whole service life.
