METHOD FOR RECYCLING WASTE OF COMPOSITE ALUMINUM SASH AND EQUIPMENT THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide both a method for recycling a waste of a composite aluminum sash by which application to the waste of the composite aluminum sash of a polyvinyl chloride resin and a urethane resin can be made and nontoxic and safe treatment can be carried out to enable demands from environmental aspects compatible with quality aspects, and equipment therefor. SOLUTION: This equipment for recycling the waste of the composite aluminum sash comprises a thermal decomposition chamber 14 for storing the waste of the composite aluminum sash, a changeover valve 15 for keeping the thermal decomposition chamber 14 in an anoxic state when a resin component consists essentially of the polyvinyl chloride resin and initially keeping the thermal decomposition chamber 14 in the anoxic state and then an aerobic state after completing the dry distillation when the resin component consists essentially of the urethane resin, a changeover valve 31 and an inert gas feeder 32 for feeding an inert gas capable of feeding the inert gas into the thermal decomposition chamber 14, a neutralizing device 20 for removing an oil component contained in the resultant thermal decomposition gas when the resin component consists essentially of the polyvinyl chloride resin, a deodorizing device 26 for the decomposition gas and a bypass valve 19 for directly leading the thermal decomposition gas from the thermal decomposition chamber 14 to the deodorizing device 26 when the resin component is the urethane resin.
