Document Type and Number:
Japanese Patent JP7412040
Kind Code:
B2
Abstract:
A dynamic and static-combined stirring system, comprising a stirrer (1), and further comprising a plurality of static stirring paddles (12) arranged parallel to a stirring shaft (2) of the stirrer (1), wherein the plurality of static stirring paddles (12) are arranged around the stirring shaft (2), and a stirring blade (4) is installed at the bottom part of the stirring shaft (2). The dynamic and static-combined stirring system is used to carry out a process for preparing a chromium salt by chromite liquid phase oxidation, and the chromite liquid phase oxidation method is used to prepare the chromium salt, which solves the key process problems of solid-liquid separation during a chromite leaching process, the separation of chromium salts in high-alkali media, and the conversion of intermediate products into a series of chromium salts, and has great industrial application prospects.
