引言

近年来,国内石油化工行业安全事故频发,化学品罐区多次发生泄漏、火灾或爆炸事故,先后发生的大连中石油国际储运有限公司2010年“7•16”输油管道爆炸火灾、中石油大连石化公司三苯罐区2013年“6•2”爆炸火灾、中石化扬子石化公司2014年“6•9”酸性水储罐爆燃等事故给国家造成了重大财产损失并造成了重大社会影响,暴露出部分单位化学品罐区在监测监控、设备设施管理、安全设计等方面仍存在突出的事故隐患和问题[1],因此,国家安全总局颁发了《关于进一步加强化学品灌区安全管理的通知》(安监总管三[2014]68号)文件[1],要求:进一步完善化学品罐区监测监控设施。要求设置储罐高低液位报警,采用超高液位自动联锁关闭储罐进料阀门和超低液位自动联锁停止物料输送措施,确保系统安全运行,由此可见,储罐液位控制是储罐系统安全控制的关键因素,因此,研究开发和准确应用智能化高精度储罐液位控制开关对易燃易爆、有毒有害气体的化学品罐区的监测监控和安全运行具有重要的意义。
