Abstract:In order to improve capture efficiency of traditional filter for PM2. 5,the agglomeration of homopolar and heteropole charged par-ticles in alternating electric field,coulomb agglomeration of heteropole charged particles,agglomeration of heteropole charged particles in direct-current electric field were introduced. The development direction of electric agglomeration was analyzed. The agglomeration effects of heteropole charged particles in alternating electric field was the best. The two-area filter had better fine particle capture performance than the three-area filter. The low temperature plasma electric agglomeration equipment was placed directly in pipe to precharge dust. A doub-le-beam electric cage bag filter was developed based on the original bag filter. Based on the new bag filter,a compound reactor which could remove S,NOx and Hg at the same time had tight structure and small volume. Its dust removal efficiency was able to reach 99%.
