SYSTEM AND METHOD FOR PREPARING TITANIUM SLAG
Document Type and Number:
WIPO Patent Application WO/2018/090867
Kind Code:
A1
Abstract:
Disclosed are a system and method for preparing a titanium slag. The system comprises: a material-mixing device (100), the material-mixing device (100) being provided with an iron-containing titanium ore inlet (101), a reducing agent inlet (102) and a mixed material outlet (103); a plurality of material bins (200), the material bins (200) being connected to the mixed material outlet (103); a rectangular electric furnace (300), the rectangular electric furnace (300) comprising: a rectangular electric furnace body (31), a plurality of electrodes (32), a first material-feeding area (33), a second material-feeding area (34), a third material-feeding area (35), a molten iron outlet (301), a titanium slag outlet (302) and a coal gas outlet (303); a residual heat boiler (400), the residual heat boiler (400) being connected to the coal gas outlet (303); and a bag collector (500), the bag collector (500) being connected to the residual heat boiler (400). The method comprises: supplying an iron-containing titanium ore and a reducing agent to a material-mixing device (100) for mixing so as to obtain mixed materials; storing the mixed materials in a plurality of material bins (200), and the material bins (200) respectively supplying same to a first material-feeding area (33), a second material-feeding area (34) and a third material-feeding area (35) of a rectangular electric furnace and carrying out melting processing so as to obtain molten iron, titanium slag and coal gas; supplying the coal gas to a residual heat boiler (400) for preheating and recycling so as to obtain cooled coal gas; and supplying the cooled coal gas to the bag collector (500) for dust collection so as to obtain purified gas.
