Title:
鋳造ラインで発生する有害物質の処理方法および処理システム
Document Type and Number:
Japanese Patent JP5435364
Kind Code:
B2
Abstract:
A method and a system for treating hazardous materials by insolubilizing the hazardous materials, such as heavy metals and halogen, that are contained in collected dust are provided. Only a small facility must be added to a foundry line. The foundry line reuses molding sand by performing the steps of shaking out a casting (14), reclaiming the molding sand (11), and mulling the sand (10). The collected dust that has been generated in the foundry line is transported to the step of mulling the sand to mull the molding sand with the dust and an insolubilizing agent. Thus the hazardous materials are insolubilized. Since no facility for insolubilizing the hazardous materials is required, the cost for facilities can be reduced. Further, if the treated sand is reused for a raw material for cement or a roadbed, no hazardous materials elute.
