摘要
为了有效提高加油站二次油气回收中的挥发油气,介绍了关键指标气液比和有较大影响的液阻及密闭性的概念,以及我国与美国及德国有关加油站油气回收系统检测的相关标准和要求,并以某地5座加油站二次油气回收气液比波动的监控统计数据具体分析了波动的主要原因,包括油品组分、汽油挥发率以及设备完好率的影响,提出了提高气液比达标率的改进方法:一是规范加油操作;二是将集中式油气回收改为分散式油气回收;三是推出电子式气液比调节阀;四是提高二次油气回收设备的完好性。指出只有在检测和认证条件下,通过相对稳定的工况条件,进行有效的预调节后,才能实现标准要求的1.0~1.2的认证值,同时对油气回收的相关标准提出了修改建议。
Based on the brief introduction of the relevant standards and requirements for detection of oil vapor recovery system of gas stations in China,the United States and Germany,the relevant data of fluctuation of gas-liquid ratio of the secondary oil vapor recovery system in five gas stations in a certain district is compared,and it is pointed out that the fluctuation of gas-liquid ratio is affected by the components of oil,the volatilization rate of gasoline and the intact rate of equipment.The measures to improve gas-liquid ratio are proposed,such as regulating oil refueling operation,replacing centralized oil vapor recovery by decentralized method,applying electronic gas-liquid ratio control valve,and ensuring the integrity of secondary oil vapor recovery equipment.At the same time,some suggestions are put forward to modify the relevant standards of oil vapor recovery.
