When using their boiling point characteristics for condensation separation, the boiling points of some gases are very close, and the internal temperature of the separation device cannot be accurately controlled, which will cause gases with similar boiling points to still mix together. This solution has a high error rate for the separation operation of mixed gases. The utility model operates the control knob 42 to accurately control the semiconductor refrigeration plate 32 through the controller 43 to start working.

In the present specific embodiment, the surface of the control knob 42 is electrically connected to the controller 43, and the surface of the controller 43 is electrically connected to the semiconductor refrigeration plate 32. The mixed gas enters the interior of the separation cylinder 2, and the control knob 42 is turned to control the semiconductor refrigeration plate 32 through the electrically connected controller 43 to start working.
