| 摘 要： | 采用国标建议的实验装置,对普通针刺毡滤料和高密面层针刺毡滤料的性能进行系统实验与研究,得出了滤料阻力性能的数据.结果表明:高密面层滤料体现了表面过滤的特征,无论在洁净过滤阶段、老化阶段还是稳定过滤阶段都具有较低的阻力值、缓慢的阻力上升速度、较长的过滤周期、较高的粉尘剥离率.因此高密面层滤料结构优于普通滤料.

| Abstract: | With an experimental setup used according to the National Standard,the filtration performance of both the common and high-density surface needle-punched felt as filters was systematically investigated,and the data of filtration resistance were obtained.The results showed that the high-density surface needle-punched felt as a filter shows the typical characteristics of surface filtration at different filtering stages,i.e.,the fresh,aged,and stabilized filters are used sequentially.The high-density surface ne... |
