摘要：

针对某石化公司1 100 kt/a乙烯装置烧焦罐内件与本体损坏严重，焦粒沉降分离效果下降的问题，对现有设备进行改造。借鉴微旋流分离技术，分析旋喷分离器工作原理，通过CFD模拟分析旋喷分离器内部流场，得到旋喷分离器内部流场和微观液相射流破碎雾化。通过DPM模型比较不同条件下旋喷分离器的除尘效率和粒子轨迹，并对除尘效率进行分析。研究结果表明，旋喷分离器在乙烯装置烧焦罐中具有良好的应用前景。

Abstract:

In response to the serious damage to the internal components and body of coke burning drum in the 1.1 Mt/a ethylene plant of a petrochemical company as well as the decrease in the settling and separation effect of coke particles, the existing equipment has been renovated. Drawing on the micro cyclone separation technology, this article analyzes the working principle of rotary jet separator. The internal flow field of the rotary jet separator is analyzed through CFD simulation, obtaining the internal flow field of the rotary jet separator and the microscopic liquid phase jet fragmentation and atomization. The dust removal efficiency and particle trajectory of the rotary jet separator under different conditions are compared using a DPM model, and the dust removal efficiency is analyzed. The research results indicate that rotary jet separator has good application prospects in the coke burning drum of ethylene plant.
