Modular reflux sampler

Abstract

The present invention relates to a modular reflux sampler, including a condenser container and a vortex tube. The condenser container is enclosed outside a gas pipeline to be cooled; the vortex tube has a cold air nozzle; the cold air nozzle extends into the condenser container to inject cold air in order to cool the gas pipeline; the vortex tube is connected with a compressed air duct to input compressed air as a cold air raw material; wherein the compressed air duct has a section to pass through the condenser container; and the vortex tube cools the compressed air duct while cooling the gas pipeline, so that the temperature of the compressed air flowing into the vortex tube is reduced, the temperature of the cold air ejected by the cold air nozzle is reduced, the cold air with a lower temperature is input to the condenser container to repeat cooling operation, and a better cooling effect is achieved.
