The invention relates to the structure design of an online sampling device and discloses the online sampling system. The online sampling system comprises a heat insulation box, an import module and an export module, wherein the import module is arranged in the heat insulation box; the import module comprises a collecting unit and a storage unit; the collecting unit is connected with a reaction vessel and is used for successively collecting N detection samples from reaction products; the storage unit is connected with the collecting unit and is used for successively storing N detection samples; N is natural number and is more than 1; the export module is connected with the import module and a detector; the export module is used for successively exporting N detection samples to the detector; the import module and the export module are used for simultaneously switching work under collecting mode or exporting mode, so as to online collect and export multiple detection samples. Thus, the online sampling system can realize online sampling under a constant temperature condition, and the pipeline blockage in the online sampling system resulted from the polymerization and splitting of the reaction products caused by ultralow temperature is avoided.
Description
technical field [0001] The invention relates to the structural design of an on-line sampling device, in particular to an on-line sampling system which has a heat preservation effect and can continuously collect and store a plurality of detection samples. Background technique [0002] In the actual operation of the catalyst evaluation device, it is necessary to conduct online sampling and qualitative analysis of the reactor product under stable conditions. The sampling process of the sample should not affect the operation of the reactor system, such as pressure fluctuations. At the same time, the collected samples need to be directly sent to the chromatographic analysis by the carrier gas to obtain the components of the samples. In order to ensure that the collected samples are representative and have no interference with the current system, the collection process requires fast and stable conditions. [0003] like Figure 1A , 1B Shown is a schematic diagram of the first an...
