Title:
WASTE SOLAR CELL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/004781
Kind Code:
A1
Abstract:
This waste solar cell processing method is for continuously processing waste solar cells, and comprises a heating step in which a solar cell module having a resin back sheet, etc. is heated in a thermal decomposition furnace so as to melt and oxidatively decompose a resin component included in a solar cell module, the method being characterized in that: the heating step is carried out by mounting the solar cell module on a porous ceramic support body (A) and moving the ceramic support body (A) through the thermal decomposition furnace from an entrance toward an exit of the furnace in a state where the ceramic support body is mounted on a porous material (B) carrying a transition metal oxide; and the thermal decomposition furnace includes, inside thereof, a temperature raising section at a stage where the temperature of the solar cell module rises, and a combustion section at a stage where the resin component oxidatively decomposes, and an oxygen concentration in the combustion section is controlled in a range of 6 vol% to less than 15 vol%.
