The invention belongs to the field of
flue gas dust removal and desulfurization
environmental protection, and particularly relates to a
coupling enhanced type electric bag composite dust remover, which adopts a two-stage or three-stage different-aperture filtering technology,
electric field structures are arranged in front of and behind filter bags, the first stage is a stainless steel
metal filter bag, the aperture of the filter bag is large, and 80% of dust can be intercepted; the second stage adopts a
fiber woven mesh filter bag, the aperture of the filter bag is medium aperture, and 15% of dust in the original
flue gas can be intercepted, and the third stage adopts a
fiber woven mesh filter bag, the aperture of the filter bag is small aperture, and 5% of dust in the original
flue gas can be intercepted; the electric fields are respectively arranged in front of and behind the second-stage filter bag and the third-stage filter bag, and the charge property of dust is increased by utilizing the front and rear electric fields, so that fluffy and ordered dust layer structures are formed on the surfaces of the second-stage and third-stage
fiber woven mesh
cloth filter bags, and meanwhile, dust on the surfaces of the filter bags can be captured again by the
electric field anode plates when being blown into the front and rear electric fields during blowing; reentrainment of dust can be effectively prevented, and the dust removal efficiency of the dust remover is improved.
