摘　　要：在当前普遍采用的加油站真空辅助式第二阶段油气回收系统中,为了避免回收到地下储油罐中的油气再次通过P/V阀排空,必须对其中气相空间的压力实施有效控制。从国外的发展情况来看,地下储油罐的压力管理系统主要分为基于膜分离技术、基于弹性气囊和基于活性炭吸附三大类,其中膜法油气回收装置在国内已经得到了较多关注。首次系统介绍了气囊式压力管理系统的工作原理及其主要结构设计,具体包括管线布局、钢制压力容器壳体、位于容器顶部封头上的接口组件和全部位于容器内的气囊等;同时对另外一种可行方案进行了分析。In the vacuum assisted stage II oil vapor recovery system which is widely used for refueling service stations nowadays, the pressure of the gas space in the underground storage tank （UST） must be kept under control, so as to prevent the oil vapor recovered to the UST from emission through the pressure/vacuum relief valve once again. According to the current developing status abroad, the vapor space pressure control systems for UST mainly comprises three types, i. e. , one based on membrane separation,one based on bladder and the other based on activated carbon adsorption. Much attention has been paid onto the first type which completes the task through a so-called membrane-method vapor recovery unit. The working principle and main structure design of the bladder vapor space pressure control system for UST were introduced systematically, including pipeline packing, steel pressure vessel shell, the interface component on the top head and the bladder in the vessel. Meanwhile, another feasible scheme was analyzed.
