Method and its device for producing catalyst grade super high purity Sb2O3

The present invention discloses process and apparatus for producing catalyst grade superhigh purity Sb2O3. The production process includes the following steps: spraying 0.1-0.8 MPa compressed air from the top of antimony oxide furnace to antimony liquid; electrically heating the furnace to over 1100 deg.c and the central reaction area to over 1200 deg.c, or leading the Sb2O3 fume from the hearth to one high temperature reaction chamber and heating the Sb2O3 fume fast to 1100-1600 deg.c; cooling suddenly the high temperature Sb2O3 fume inside the quickly cooling device, and collecting with cloth bag to obtain the Sb2O3 product. The present invention has low power consumption, high yield, low production cost and other advantages.
