电除尘器带屏蔽管电晕线组的研究

带电晕屏蔽管电晕线组的研究 ,适应环保标准日益严格和燃煤电厂大量燃用低硫煤的现状。这种新的极配形式可以随工况的变化来调节屏蔽管的位置 ,并可抑制电晕电流的强度 ,使之能够在“高电压低电流”的安全状态下稳定运行 ,它还能使收尘极板电流密度均匀化 ,从而可以有效地减弱或克服反电晕以及节约能源

STUDY ON CORONA WIRE GROUP WITH SHIELDING TUBE IN ESP

The study on the corona wire group with shielding tube in ESP adapts to the situation of the strict environmental standard increasingly and substantive coal with low sulphur for coal fired power plants. The new match model can adjust the position of shielding tube according to the situation of power plant, so as to restrain the intensity of the corona current, which can make the ESP work in the safety situation of “high voltage and low electric current”, and it can equalize the plate electric current density, so that it weakens or restrains the anti corona and saves energy.
