摘　　要：燃煤电厂大多利用蒸汽或烟气余热干化污泥后,再将污泥掺烧发电。污泥干化过程产生的尾气含多种无机或有机污染组分,如不当处置极易造成二次污染。本文系统分析了污泥干化尾气中污染物释放特性及其影响因素,研究了尾气污染控制方法,以期为燃煤电厂内污泥干化过程二次污染防控提供参考。Most of the coal-fired power plants firstly dry the sludge using waste heat of steam or flue gas,and then combust the sludge with coals to generate electricity.The tail gas generated from sludge drying process contains a variety of inorganic or organic pollution components,which would cause secondary pollution easily if not properly treated.This paper systematically analyzes the release characteristics and influencing factors of pollutants in sludge drying exhaust gas,and studies exhaust gas pollution control methods,in order to provide a reference for the prevention and control of secondary pollution during sludge drying in coal-fired power plants.
