| 摘 要： | 研究了脉冲清灰效率对过滤过程的影响。假定粉尘结构在过滤和清灰中不变的条件下,对清灰效率的影响进行了分析。发现,在一定的启动压降下,有一个最佳的清灰效率,在90%～95%之间。由于在运行的前几个循环中,粉尘压降、残留粉尘压降以及粉尘厚度、残留粉尘厚度存在较大的变化,因而在开始的几个循环中,不宜采用相同的清灰时间间隔。

| Abstract: | Assumption that the structure of the filter cake doesn ' t change in the filtration and pulse cleaning process,the effect of pulse cleaning efficiency on the filtration has been analyzed.Results show that the pulse cleaning efficiency reach its optimal value of90%-95%at certain start pressure drop.Because of the great change of the thickness and pressure drops of filter cake and rudimental filter cake in the first several filtration cycles,different interval time should be used according to pressure drops of cakes. |

| Keywords: | candle ceramic filter pressure drop filter cake pulse cleaning efficiency |
