摘要 催化裂化油浆含有一定量(2g/L以上)的固体颗粒,严重影响其使用性能,须将其净化。介绍催化裂化油浆的组成特点和静电净化法的基本原理,总结国内外静电分离器的研究进展,重点阐述静电分离器状况(进料流向、装置填料、电极等)对静电分离效率的影响。分析发现B型径向型分离器具有较高的净化效率;电极振荡预处理操作能有效地降低油浆的黏度,提高静电分离效率;含有5%~40%钾氧化物的玻璃珠为静电分离器的优质填料;长期使用的填料需用无机酸定期处理,以保持填料的高效性;静电分离器的内部结构(电极等)尺寸匹配、安装合理时,分离器才能产生较好的分离效果。 FCC slurry contains certain amount of solid particles ( 〉 2 g/L) which severely limit the scope and the utilization performance of the application of slurry. Therefore, solid particles have to be removed. Composition characteristics of FCC slurry as well as basic principles of electrostatic separation are reviewed, and research and development regarding to electrostatic separator both in China and abroad are summarized. Furthermore, impacts of electrostatic separator( flow of feed, packings, electrode) on electrostatic separation efficiency are emphatically studied. The analysis has found that B-radial type electrostatic separator offers a higher separation efficiency in purification of FCC slurry. FCC slurry pretreated by electrode oscillating has a lower viscosity and a higher efficiency in particles removal. Smooth glass beads containing 5% -40% potassium oxides are excellent separation packings of electrostatic separator. The glass beads which are used many times need to be cleaned by inorganic acid to remove deposited metals to maintain its efficiency. Only when the internal structures of the electrostatic separator match well and are installed properly, can the separator have a good separation performance.
