结合大型外浮顶储罐的结构特点，通过采样分析、安全判定、惰化保护3个过程，实现对大型石油储罐密封圈的主动安全防护。气体取样泵对储罐密封圈环形气囊不同分区内的混合气体进行自动巡回取样，进行氧气浓度分析和可燃气浓度检测，检测结果传输给PLC系统进行判定。当判定结果为危险时，系统自动启动惰化保护。

Based on the structural features of large outward floating roof tank,three processes of sampling analysis,safety judgment and deactivation protection are implemented to realize the active protection of seal rings of large petroleum storage tanks. The gas sampling pump is used to make automatic touring sampling of the gas mixture in different zones of circular gas bags of storage tanks seal rings and make oxygen concentration analysis and flammable gas concentration detection. The detection result is transferred to PLC system for judgment. When the judgment result is danger,the system automatically initiates deactivation protection.
