PROCESSING METHOD AND PROCESSING DEVICE OF WASTE LIQUID CRYSTAL PANEL

摘要

PROBLEM TO BE SOLVED: To safely and surely process an organic material in a liquid crystal panel by a simpler method. SOLUTION: A waste liquid crystal panel 10 is disposed in a chamber 21 and the pressure and the temperature in the chamber 21 is set to be 0-40 kPa and 200-400 deg.C, respectively, to gasify the organic material constituting the waste liquid crystal panel 10. The waste liquid crystal panel 10 is disposed in the chamber 21 in the state that two glass substrates 11 and 11 constituting the panel are crashed. Carrier gas is introduced into the chamber 21 and the gasified organic material is exhausted to the outside of the chamber 21. The resultant organic gas exhausted to the outside of the chamber 21 is introduced into an organic gas decomposing device to decompose the organic gas into an inorganic gas and water in the decomposing device. An organic component contained in the gas formed by decomposing the organic gas is detected by a gas sensor 27 and when the concentration of the organic component in the gas detected by the gas sensor 27 is a prescribed value or higher, the decomposed gas is fed back to the organic gas decomposing device.
