LFEF袋除尘器在立窑晶种煅烧工艺下的应用

安徽省东关水泥厂立窑采用晶种煅烧工艺后，原用ＬＦＥＦ袋除尘器出现了结露等一系列不良工况，为此，该厂对其采取了强化密封，减少漏风；进风管上设置水冷蝶阀和冷风阀调控温度，选用经特殊表面处理的抗结露滤料和微机自动化控制系统等技术措施，确保了ＬＦＥＦ除尘器的正常运行。文章对立窑等用品种煅烧工艺，ＬＦＥＦ除尘器的操作技术和不良工况的处理措施也作了详细介绍。

Application of LFEF bag filter in the process of burning crystal seed by shaft kiln

After adopting crystal seed burning in shaft kiln, the existing LFEF bag filter appeed a serial of abnormal working condition like dew etc. The plant tightened the sealing to minimize the air leakage and added cool water butterfly valve at duct inlet and its temperature control. Dew - proof filtering material with its surface specially machined and ndcro compuler conbol system etc. were also adopted, which ensured the normal operation of LFEF bag filter. Detall inwhuction of the crystal seed burning in the shaf kiln, the operation tech11ologr of LFEF hag filter and measures to deal with its abnormal working conditionis given in this article.
