摘要(Abstract):

为了解决在干法除尘煤气化技术中广泛使用的飞灰过滤器陶瓷滤芯断裂问题,以神华煤制油装置飞灰过滤器为研究对象,将采用Fe3Al材料制得的滤芯在过滤器中使用。通过测定合成气及飞灰特性、过滤效率、流量-压差曲线、滤饼孔隙率等来分析这种新型材料的性能。结果表明:该滤芯在处理量3×105m3/h情况下,压差稳定控制在20 kPa左右。同时具有良好的耐H2S腐蚀能力,轻微表面腐蚀产物为颗粒状FeS,直径小于0.5μm,可以实现在煤气化装置中的稳定应用。
The ceramic filter element in fly ash filter frequently broke in the process of dry-type dust collection.To resolve this problem,taking the fly ash fliter installed in Shenhua coal to liquid facility as research object,developed a new type filter element which is made of Fe3Al.The characteristics of this advanced material was tested by analysing properties of synthesis gas and fly ash,collection efficiency,differential pressure flow curve,filter cake porosity.The results show that,the filter element can stabilize the differential pressure at 20 kPa while the processing capacity is 3×105 m3/h.The Fe3Al filter element has good resistance from H2S corrosion.Even if its surface is slightly corroded,the thickness of corrosion products(FeS) is 0.5 μm,so it can stably run in the gasification devices.
