煤沥青中喹啉不溶物(QI)的旋风分离

Removal of Quinoline-Insolubles (QI) in Coal Tar Pitch by Gas Cyclones and Swirl Tubes

摘要: 本文分析了QI在煤沥青中的存在形式，结合高速气体破碎和旋流分离的有关知识，提出了首先使用高速气体将煤沥青液体雾化，然后使用旋风分离器分离其中的QI。实验数据表明：此方法能顺利将煤沥青中QI的脱除，使其含量低于1%。雾化颗粒的微观分析，也验证了此方法的理论基础。由于这种方法与工业上其他常用的方法相比，在能量消耗方面存在着巨大优势，因此本研究为工业上脱除QI提供了一种新的思路。

Abstract: This paper analyzes the status of QI in coal tar pitch, considering knowledges of smashing by high-speeding gas and gas cyclones, a means of removal of QI is advanced that liquid of coal tar pitch is atomized firstly by high-speeding gas and then removing of QI in coal tar pitch by gas cyclones and swirl tubes. The datas certify that QI can be removed from Coal tar pitch in this means and the level of QI is below 1%. Analyzing granule of Coal tar pitch in micro-aspects verifies the theoretical basis of this method. Because this means compares with other methods used in industry, there is huge advantage in energy consumption. So this study provides a new means of removing QI in coal tar pitch in industry.
