Zusammenfassung: | According to the VOC pollution source remote sampling system provided by the invention, three sets of branch paths are used for remote switching connection, introduction, collection and cleaning of sampling gas are realized, the first branch path introduces the sampling gas to exhaust environmental gas, the sampling gas introduced by the third branch path is ensured not to be mixed into the original environmental gas, and the sampling gas is prevented from being mixed into the original environmental gas. The second branch blows the environment gas back to provide a clean environment for the next gas collection, and certainly, the first branch introduces the sampling gas again to exhaust the environment gas in the next gas collection process. The three branch paths are converged at the same common connection point A and share the same gas conveying pipe, so that the collection of sampling and cleaning functions is realized, and therefore, the three branch paths can be integrated in the same control box, the mi |
