PROCESSING METHOD OF CHLORINE BYPASS DUST AND PROCESSING EQUIPMENT OF CHLORINE BYPASS DUST
PROBLEM TO BE SOLVED: To provide a processing method of a chlorine bypass dust, capable of responding to increase in an amount of chlorine brought to a cement kiln.SOLUTION: The processing method of a chlorine bypass dust contains: an extraction step of extracting a combustion gas from a probe 1 between an end part of a cement kiln K and a lowermost cyclone of a pre-heater P as an extraction gas G; a cooling step of cooling the extraction gas G and condensing and solidifying chlorine involved in the extraction gas G to give a chlorine bypass dust; a classifying step of classifying the chlorine bypass dust based on a predetermined particle size to a first dust D1 which is a coarse powder and a second dust D2 which is a fine powder; and a heating step of heating the second dust D2 to evaporate chlorine-containing matters.SELECTED DRAWING: Figure 1
【課題】セメントキルン内に持ち込まれる塩素量の増加に対応できる塩素バイパスダストの処理方法を提供する。【解決手段】塩素バイパスダストの処理は、セメントキルンＫの窯尻とプレヒータＰの最下段サイクロンとの間のプローブ１から燃焼ガスを抽気ガスＧとして抽気する抽気工程と、抽気ガスＧを冷却して、抽気ガスＧに含まれる塩素を凝縮固化させて塩素バイパスダストとする冷却工程と、塩素バイパスダストを所定の粒径を基準に粗粉である第１ダストＤ１と微粉である第２ダストＤ２とに分級する分級工程と、第２ダストＤ２を加熱して、塩素含有物を揮発させる加熱工程とを備える。【選択図】図１
