摘要
对近年来一些加油站依据《GB 20952-2007加油站大气污染物排放标准》安装的三次油气回收系统运行效果不十分理想的问题,从产品设计、标准规定和运维监管等方面进行了分析,提出了改进建议:一是在油气回收系统真空泵后的油气管道上增加一台流量计;二是在解析泵后的管道上增加一个气/液分离计量筒;三是在膜组件之后的排气管上增设一个油气浓度传感器;四是在PLC和触摸屏内增加“油气回收系统运行自诊断”程序;五是PLC装置与环保检测部门联网的RTU装置进行整合;六是合理储备油气回收装置易损件;七是在油气回收系统膜组件后对空排放管上安装一台油气浓度传感器;八是建议对有关标准进行修订。
In recent years,the operation effect of the tertiary oil vapor recovery system installed in some gas stations according to national standard"Emission standard of air pollutant for gasoline filling stations(GB 20952-2007)"is not very ideal.This problem is analyzed from the aspects of product design,standard provisions,and operation and maintenance supervision.Suggestions for improvement are put forward:a flowmeter is added to the oil vapor pipeline after the vacuum pump;a gas/liquid separation metering cylinder is added to the pipeline after the desorption pump;an oil vapor concentration sensor is added to the exhaust pipe after the membrane module;a program of"self-diagnosis of oil vapor recovery system operation"is added to PLC and touch screen;the PLC device is integrated with RTU of the environmental detection department on internet;the vulnerable parts are reasonably reserved;and the relevant standards should be revised.
