摘　　要：针对传统的储罐机械清洗设备及其技术在部分环节上的不足,提出了具体的改进措施:将一罐增加为两罐,使离心泵始终在常压状态下工作;将制氮机与氧气检测仪联动运行,以安全控制罐内氧气的体积分数;将油水分离装置改成自动密闭撇油容器,以防止油气扩散,降低人员劳动强度;安装气动控制阀门,避免人员在油罐浮顶上切换清洗机,增强了安全保障。通过真空回收、监测、撇油、清洗机切换等技术改进和创新,引导油罐底泥清洗技术向高效化、密闭化、自动化的方向发展,值得普遍应用与推广。Considering certain deficiencies of traditional mechanical cleaning equipment and process of tanks, specific improvements are proposed. Firstly, the number is doubled to two tanks, to make the centrifugal pump operate under normal pressure at all times. Secondly, the nitrogen generator and the oxygen detector are linked to safely control the volume fraction of oxygen in the tanks. Thirdly, the oil-water separator is replaced with an automatic closed oil-skimming vessel to prevent the proliferation of oil and gas and reduce the labor intensity. Fourthly, the pneumatic valve is installed to avoid artificial switching of cleaner on the floating-roof of oil tank, with enhanced safety guarantee. Combining technical improvements and innovations of vacuum recovery, monitoring, skimming and switching of cleaner, the cleaning of sediment at tank bottom is directed towards an efficient, closed and automatic technique. This concept is worthy of extension and promotion.
