摘要
为分析静电分离法脱除催化裂化油浆中固含量影响因素,采用自制静电分离器试验装置,研究填料直径和材质对催化油浆中催化剂固体颗粒脱除效率影响规律。结合数值模拟,分析填料直径和材质对其接触点处电场强度变化的影响。结果表明,油浆中固体颗粒分离效率随填料直径增大而降低,氧化锆填料的分离效率最高,玻璃填料的分离效果最差。随填料直径和填料相对介电常数增大,填料接触点处的电场强度增大。在不同材质填料物化参数中,填料相对介电常数对油浆中固体颗粒静电分离影响过程起主要作用。
In order to analyze the factors affecting the removal of solid content influid catalytic cracking(FCC)slurry by electrostatic separation,a self-made electrostatic separator test device is used to study the effect offiller material and diameter on the removal efficiency of catalyst solid particles in FCC slurry.Combined with numerical simulation,the influence of packing diameter and material on the electricfield strength at the packing contact point is analyzed.The results show that the separation efficiency of solid particles in oil slurry decreases with the increase of packing diameter.Zirconiafiller has the highest separation efficiency,and glassfiller has the worst separation effect.The electricfield intensity at the contact point of thefiller increases with the increase of thefiller diameter and the relative dielectric constant of thefiller.Among the physicochemical parameters of differentfillers,the relative dielectric constant offillers plays a major role in the process of electrostatic separation of solid particles in oil slurry.
