靜電除塵(Electrostatic Precipitation) 是一種利用靜電力從氣流中分離懸浮顆粒物的高效空氣污染控制技術。其核心原理是通過高壓電場使氣體電離,顆粒物帶電後在電場力作用下被吸附到收集極上,最終通過清灰裝置去除。該技術廣泛應用于燃煤電廠、鋼鐵冶煉、水泥生産等工業領域,可高效捕集PM2.5等細顆粒物,除塵效率可達99%以上。
氣體電離與顆粒帶電
含塵氣體通過高壓電場(通常30-70kV)時,電暈極放電産生離子,氣體分子被電離形成正負離子流。懸浮顆粒與離子碰撞後捕獲電荷,實現帶電過程(美國環保署工業控制技術文檔)。
顆粒遷移與收集
帶電顆粒在電場庫侖力作用下向極性相反的收集極(金屬闆/管)定向移動,吸附在極闆表面形成粉塵層。遷移速度遵循多伊奇方程(Deutsch Equation):
$$ eta = 1 - e^{-frac{wA}{Q}} $$
其中$eta$為除塵效率,$w$為顆粒驅進速度,$A$為集塵面積,$Q$為氣體流量(加拿大環境部空氣污染控制手冊)。
清灰與回收
通過機械振動或聲波震蕩使沉積粉塵脫落至灰鬥,幹法收集的飛灰可用于水泥原料等資源化利用(IEEE靜電應用期刊)。
現代靜電除塵器結合脈沖供電技術提升高比電阻粉塵處理能力,并通過智能控制系統實時優化電壓波形,使能耗降低15%-20%的同時增強工況適應性。全球最大單機應用案例為印度薩桑電廠1300MW機組配套ESP,處理煙氣量480萬m³/h。
