| 摘 要： | 通过喷吹实验台对Ф147×1 000mm滤筒的脉冲喷吹清灰过程进行了实验测试,运用数据采集系统得到了滤筒表面压力峰值的动态变化曲线图;并利用CFD模拟滤筒的清灰过程,计算过程采用非稳态计算方法,得到了不同喷吹时刻滤筒表面的压力峰值。在喷吹压力一定的条件下,沿滤筒长度方向上,正压力峰值到达时间是逐渐增加的;滤筒内压力峰值并非随着喷吹时间的增加而不断增大,当喷吹时间大于60ms时,随着喷吹时间的增加压力峰值有下降趋势。模拟得到的压力峰值曲线与实验曲线变化趋势一致。

| Abstract: | By testing the jet-cleaning process of a filter cartridge of 147×1 000 mm in size on a jet experiment platform,obtains a dynamic change curve of peak pressure by means of a data collection system.Adopting CFD to simulate the jet-cleaning process of the filter using an unsteady calculation method,gains the peak pressures at different pulse-jet times.The occurring time of positive peak pressure is gradually increasing along the length direction of the cartridge under a given jet pressure.The increase of the peak pressure in cartridge does not increase with the jet time and the peak pressure has a decrease trend when the jet time is longer than 60 ms.The variation trend of the peak pressure curve from simulation is accordant with the one from the experiment. |
