New fluidization technology for treating with waste industrial salts

提出了几种可以检测分析工业废盐中有机物种类和含量的方法和技术手段,热重分析确定了工业废盐的失重率以及产生失重所需的温度范围,红外光谱分析检测出工业废盐中有机物所含的官能团,气质联用检测出废盐中可能含有的有机物种类,滴定法确定了氯化钠的纯度等。运用流化床装置采用空气对工业废盐进行处理,对固相产物进行了红外光谱分析以及电镜扫描,通过对比发现有机物得以很好地去除。

This paper presents several methods and technical means for detecting and analyzing the types and contents of organic substances in waste industrial salts. The thermogravimetric analysis can be used to determine the weightlessness rate of waste industrial salts and the temperature range required by weightlessness. The infrared spectrum analysis is employed to detect functional groups contained by organic substances in waste industrial salts. The types of organic substances possibly contained in waste industrial salts can be detected by GC-MS. The purity of sodium chloride can be checked by titration method,etc.The waste industrial salts are treated by air in a fluidized bed device. The solid phase products are detected by infrared spectroscopy and scanning electron microscopy,the organic substances can be found by comparison and then are removed efficiently.
