Fractionation gas sampling device

Abstract

The present application discloses a gas sampling device, in particular, a fractionation gas sampling device comprising a heat exchanger, and the heat exchanger comprises one or more groups of tubes, wherein, a guide plate is disposed in the tubes. The fractionation gas sampling device further comprises a coke cleaning mechanism having a decoking head, and the decoking head has a circular arc guide. The fractionation gas sampling device has a large heat exchange area, a high heat exchange efficiency, and overcomes the surface tension between liquids so as to avoid generating liquid columns; moreover, by combining with the coke cleaning mechanism, the fractionation gas sampling device not only achieves excellent technical effects relevant to decoking, but also effectively prevents from a blocking phenomenon of the decoking head, thereby realizing an automatic cleaning.
