The analysis data is finally transmitted to the data processing device 300 for sorting and collection.

Generally, the rock desorption system 1000 has a simple structure, can realize continuous analysis of desorbed gas, has high analysis efficiency, can complete analysis data statistics, and has high processing efficiency and low data error rate.

In the present embodiment, the heating cavity 111 of the heater 110 is cylindrical, the inner container 130 is also substantially cylindrical, the inner container 130 is coaxially disposed with the heating cavity 111, and the heat transfer medium is heat transfer oil.

The air outlet of the inner container 130 is rotationally connected with the desorption gas transmission pipe and rotationally sealed.

The sidewall of the inner container 130 has a recess 131, and the recess 131 is formed by the sidewall of the inner container 130 being recessed toward the heating chamber 111 along a radial direction thereof. The recess 131 is elliptical. Along the circumferential direction of the inner container 130, the recessed portions 131 are arranged at regular intervals. The concave portions 131 are also uniformly spaced along the axial direction of the inner container 130.
