[0003] The traditional cyclone dust removal equipment has certain limitations in practical application. On the one hand, the trapping efficiency of different particle size dusts is quite different, usually for larger particle size dust particles has higher trapping efficiency, but for the fine dust with particle size less than 5 microns, especially the sub-micron dust particles, the trapping efficiency is obviously decreased, it is difficult to meet the increasingly strict environmental protection emission standard. On the other hand, the single cyclone dust removal structure is difficult to realize the hierarchical trapping of dust, cannot be targeted according to the size of dust particle diameter, is not conducive to the subsequent resource utilization and fine processing of dust.
