[0002] With the rapid development of petrochemical industry and automatic control instrument technology, the requirements for the analysis of process media are also constantly improving. The analytical laboratory set up in the safety zone can no longer meet the requirements of modern equipment for analytical response time. In order to achieve this goal, the online analyzer set up in the device area came into being. The analysis data of the online analyzer is an important parameter to guide the safe, stable and efficient operation of the process device. In order to make its analysis results accurate, the outlet pressure of the online analyzer tail gas must be kept under atmospheric pressure. However, the online analyzer tail gas kept under atmospheric pressure cannot be returned to the process pipeline. At present, the online analyzer tail gas can only be discharged directly into the atmosphere. The online analyzer tail gas is toxic and harmful gas, and the number of process analyzers is huge, so the online analyzer tail gas directly discharged seriously pollutes the atmospheric environment. Although the purpose of shortening the length of the sampling cable and reducing the sample transmission time is achieved by setting the online analyzer in the device area close to the sampling point, the recovery of a large number of samples has become a new problem that needs to be solved.
