TREATMENT METHOD FOR GLASS WOOL SCRAP AND DEVICE FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To remove the organic materials intruding and sticking into and to glass wool scrap and to decrease the amount of its residual carbon so that the glass wool scrap may be recycled as glass raw material. SOLUTION: The treatment method for the glass wool scrap for recovering and recycling various kinds of the fiber scrap discharged in a manufacturing process for glass wool products consists of a heating and combusting process of removing the greater part of the organic matter sticking to the glass by heating the glass wool scrap to a glass distortion point or a temperature near the same, a firing process of removing the residual carbon to <=0.3 wt.% and putting the glass wool scrap into a sintered state that the fibers are softened and bridged to each other by heating the glass wool scrap to a temperature exceeding the temperature of the heating and combusting process and to a glass softening point or below the same, a cooling process of cooling the glass wool scrap and a pulverizing process of coarsely pulverizing the glass wool scrap which is embrittled after the cooling and is made easier to be pulverized and the device for the same.
