Investigation of Concentration Method for Asbestos in Recycle Residue of Construction Waste

研制了建筑垃圾回收渣中x射线衍射检测石棉的预处理装置。对粉尘分散收集装置进行了改进和评价。建立了一种有效地从废渣中回收可飞石棉的方法。此外，为了防止石棉从渣中再飞，有必要通过洒水来保持含水量在10%以上。

This study developed the pre-treatment equipment for detecting asbestos by X-ray diffraction in recycle residue of construction waste. The equipment to be scattered, and to collected fine dust in the residue was improved and evaluated. As a result, a method to collect the flyable asbestos from the residue effectively was established. In addition, it was necessary for prevention of re-flying asbestos from the residue to keep water content which was higher than 10% by water sprinkling.
