卧式短滤筒除尘器脉冲喷吹清灰过程数值分析及机构优化OA
Numerical Analysis and Optimization of Pulsed-jet Cleaning of Horizontal Short Cartridge Filter
针对具有更好尺寸适配性的卧式短滤筒除尘器,采用CFD软件对除尘器的脉冲喷吹清灰过程进行了动态数值模拟.通过仿真分析了喷吹过程中滤筒内部的流速和流场压力变化,对比了长短滤筒喷吹过程中压力分布的差别.通过单因素仿真对比分析,得到喷吹压力为0.5 MPa、喷吹距离为180 mm时,该除尘器的清灰效果最为理想.此外,合理设置文氏管对清灰效果也起到了显著的作用.针对清灰压力分布不均匀的问题,提出了一种在滤筒开口处设置圆锥形导流板的机构,使喷吹气流在滤筒前部…查看全部>>
Aiming at the horizontal short cartridge filter with better size adaptability,CFD software is used to conduct dynamic numerical simulation of the dust removal process in a horizontally-oriented short cylinder dust collector with enhanced dimensional adaptability.Simulation analysis is performed to investigate the variations in flow velocity and flow field pressure within the filter cylinder during the spraying process,while also comparing the pressure distri…查看全部>>
