摘　　要：某固废处理企业在连续生产过程中,汽化炉灰水输送管在短期内连续出现腐蚀穿孔失效现象,为保障企业正常生产,需要对失效原因进行分析。本课题通过宏观检查及常规检测,介质取样分析,扫描电镜能谱分析等手段,得出腐蚀泄漏产生的原因是氯化物腐蚀和氧腐蚀共同作用的结果,并根据分析结果给企业提出合理化的建议。In order to ensure the normal production of a solid waste treatment plant,the failure reason of the ash water conveying pipe of the vaporizer is analyzed.In this paper,through macroscopic examination and routine examination,medium sampling analysis,scanning electron microscope energy spectrum analysis,it is concluded that the corrosion leakage is caused by chloride corrosion and oxygen corrosion,and according to the analysis results to the enterprise put forward the rationalization proposal.
