    • A dust removal device is provided which reduces the differences, among different dusty environments, in time at which dust collection is started until the time when possible clogging may occur to significantly increase the time from the start of dust collection until the time when possible clogging occur, while improving dust removal performance. The dust removal device includes main filter 10 that is formed of non-woven cloth 8 with charged fiber, duct 6-1 with main filter 10 disposed therein, sub-filter 11 including a plurality of cylindrical air trunks formed of a charged member, and duct 6-2 with sub-filter 11 disposed therein. Duct 6-1 and duct 6-2 are in communication with each other. In operation, air flows from duct 6-1 to duct 6-2. Main filter 10 in duct 6-1 has a larger vent cross-sectional area than sub-filter 11 in duct 6-2.
    • 提供除尘装置,其在不同的多尘环境中,在开始灰尘收集的时间内减少差异,直到可能发生堵塞的时间,以显着增加从集尘开始到可能发生堵塞发生的时间 ,同时提高除尘性能。 除尘装置包括由具有带电纤维的无纺布8形成的主过滤器10,设置有主过滤器10的管道6-1,包括由带电部件形成的多个圆筒形空气干线的副过滤器11,以及 管子6-2,其中设置有副过滤器11。 管道6-1和管道6-2彼此连通。 在操作中,空气从管道6-1流到管道6-2。 管道6-1中的主过滤器10具有比导管6-2中的子过滤器11更大的通风口横截面面积。
