A bed-type filter composed of thin metal alloy fiber was closely examined with dust capturing in cold and hot runs. The investigation of an individual mechanism across the filter bed indicated that the aerated dust could be initially collected by depth filtration, and after a while, surface filtration dominated the overall dust collection. The present metal fiber bed was comparable to the conventional ceramic filters because of its good collection efficiency with low pressure drop. It also showed potential to be used as a prefilter in a diesel exhaust trapping system.
一种由薄金属合金纤维组成的床式过滤器在冷热运行过程中进行了捕尘的详细检查。对过滤床单个机理的研究表明，充气灰尘最初可通过深度过滤收集，一段时间后，表面过滤主导了整体灰尘收集。由于其具有良好的收集效率和低压降，目前的金属纤维床与传统陶瓷过滤器相当。它还显示出有潜力用作柴油排气捕集系统中的预过滤器。
