摘　　要：本文分析了氢氧化铝气态悬浮焙烧炉在生产过程中,由于大气治理环保排放指标要求,焙烧炉除尘器需要达到超低排放的标准,否则无法评选环保A级企业,另外还会给生产企业带来无法避免的极板极线检修问题,使得生产不能稳定运行。本文借鉴长时间的设计及施工实践经验,分析问题出现的原因,提出了针对焙烧炉静电除尘器的一些应用问题,采用金属滤袋除尘器改造的具体处理方法,有利于焙烧炉稳定运行。This paper analyzes the production process of aluminum hydroxide gas suspension baking furnace,due to the requirements of environmental protection emission indicators for atmospheric governance,the dust collector of the baking furnace must meet ultra-low emission standards,otherwise it cannot be selected as an environmentally-friendly A-level enterprise.In addition,it also brings unavoidable maintenance problems to polar plates and polar lines of the production enterprise,and makes the production unable to operate stably.Through long-term design and construction experience,the causes of problems are analyzed.Aiming at some application problems of electrostatic dust collector for the baking furnace,the concrete treatment methods of reforming metal filter bag dust collector is put forward,which is beneficial to the stable operation of the baking furnace.
