摘要
针对影响污泥气化产物及产物分布状况的两个主要因素——温度和空气当量比,选用某造纸厂污水处理后的污泥作为实验材料,在内径100 mm固定床气化炉上进行空气气化实验,分别研究了不同空气当量比(0.2～0.6)和不同气化温度(500℃、600℃、700℃)等操作条件对污泥三相产物特性的影响规律。确定最佳气化温度和空气当量比,为不同的污泥气化工艺提供参考。
Aiming at two main factors affecting the sludge gasification products and the product distribution： temperature and air equivalence ratio,paper sludge was chosen as experimental material from certain sludge sewage treatment.And the air gasification of the paper sludge was performed on a fixed bed gasifier with inner diameter of 100mm.The impacts on the three-phase product characteristics of different operating conditions： air equivalence ratio（0.2 to 0.6） and gasification temperature（500 ℃,600 ℃,700 ℃）,were investigated respectively.The best gasification temperature and air equivalence ratio were determined,which can provide a reference for the different sludge gasification processes.
