1. Flue gas is administered and is used atomizing lotus electric super purifier, its characterized in that:

  • the device comprises an ultra-purification tower (1), wherein an air inlet pipe (5) for feeding flue gas into the tower is arranged in the middle of the ultra-purification tower, a chimney (7) for discharging clean flue gas is arranged at the top of the ultra-purification tower, and a blow-off pipe (6) is arranged at the bottom of the ultra-purification tower;

    an atomization spray gun (4) for spraying charged liquid to the flue gas entering the ultra-purification tower is arranged in the ultra-purification tower which is positioned above the air inlet pipe in an inclined manner;

    the atomizing spray gun is radially arranged along the cross section of the ultra-purification tower, and the included angle between the atomizing spray gun (4) and the horizontal plane where the air inlet pipe (5) is located is 30-50 degrees;

    the charged liquid sprayed by the atomizing spray gun contains a coal flow dust suppressant;

    the horizontal plane of the atomization spray gun is provided with two atomization spray guns, the included angle between the two atomization spray guns is 30 degrees, and the atomization spray guns are low-pressure two-fluid atomization spray guns;

    the coal flow dust suppressant comprises the following components in parts by mass;

    1-3% of starch grafted acrylic polymer and Sodium Dodecyl Sulfate (SDS)0.01%



    0.05%



    The preparation method of the starch grafted acrylic polymer comprises the following steps;

    with starchAs raw material, ammonium persulfate (NH)4)2S2O8Sodium bisulfite NaHSO3As initiator, propyleneAcid(s)And acrylamideFor grafting monomers, triallyl isocyanurateIs cross-linking agent, sodium hydroxide is neutralizing agent, starch is gelatinized and then prepared by aqueous solution polymerization.
