High -efficient dust removal defogging subassembly of whirl - racemization coupling

The utility model relates to a whirl the high -efficient dust removal defogging subassembly of racemization coupling, this subassembly setting spray the top on layer in the desulfurization absorption tower, including a plurality of dust removal defogging units, the defogging unit that should remove dust includes outer barrel, from bottom to top parallel arrangement sets up the hydrophobic board of racemization at the compound barrel top of cavity in the internal centrifugal whirl board of the first order, the centrifugal whirl board in the second level and the slope of urceolus in proper order, the inner wall of outer fringe and outer barrel of the centrifugal whirl board in outer fringe, the second level of the centrifugal whirl board of the first order between leave the clearance that is used for the liquid film to descend. Compared with the prior art, the utility model has the advantages that the whole structure is simple single, compact, the investment cost is low, the risk is blocked in good, the no scal
