When the impeller pipe rotates, the annular slide groove rotates along the moving ring, so that the plasma gas does not interfere with each other when it is sent into the reaction tube for reaction. The gas pressure of the jet access pipe is adjusted by the air pressure regulating valve, and the rotation speed of the impeller pipe is adjusted. The inert gas flow in the active cavity is discharged through the air outlet pipe, and the air outlet valve is connected to the external pipeline for recycling.
