<p><P>PROBLEM TO BE SOLVED: To provide a treatment method capable of performing simple and efficient re-utilization of a waste liquid crystal panel and performing inexpensive and useful re-utilization of indium oxide. <P>SOLUTION: A waste liquid crystal panel crushed product is stored in a material feeder 5, is fed to a burner 2 of a heating furnace 1, and is fed into the flame of the burner 2. Dilution air is introduced into the heating furnace 1 to adjust the temperature of the inside to 850-1,400°C. The organic substance is burned/decomposed in the heating furnace 1 and indium oxide is sublimated. The gas containing a solid content from the heating furnace 1 is fed to a cyclone 12 while retaining it to 850-1,400°C and a glass cullet is captured here. The dilution air is mixed with the gas from the cyclone 12, and the temperature is made 850°C or lower to condense the indium oxide and solidify it. It is captured and recovered by a bag filter 14. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
