介绍了陕西延长石油集团延安石油化工厂硫磺回收装置真空带式过滤机从开工运行到实施技术改造前存在的问题,包括:机架和机座腐蚀问题,裙边的老化后产生的开裂、脱落问题,滤布的纠偏问题,控制系统问题,排水系统问题,现场通风问题,轴承座防腐问题,胶带防偏等问题,并进行了改造,改造后过滤机运行良好。

The problems of vacuum belt filter of sulfur recovery unit in Yanchang Petroleum Co. , in Shaanxi, were introduced. The problems in the start - up and operation to the implementation of technological reconstruction contained such as the corrosion of rack and foundation, the crack and shedding which were caused by ageing skirt, the deflecting correction of filter cloth, control system, drainage system, spot ventilation, corrosion protection of bearing chock and the deflecting prevention of belt.
