Embodiment Construction

[0009] refer to figure 1 , 2 It is an embodiment of the present invention. The magnetic drive device 12 is connected with the upper cover 5 of the autoclave by bolts, and a sealing gasket is placed in the middle for sealing. The high-pressure gas cylinder air-conducting pipe and the autoclave air-inlet pipe 6 are connected by screw fasteners. The three-electrode system is connected to an external electrochemical test instrument through a signal conduction pathway. The autoclave control box is wired to the components on the autoclave. The experimental gas released from the high-pressure gas cylinder enters the reaction kettle through the air inlet pipe 6 to generate a high-pressure experimental environment, and the dielectric solution in the kettle is heated to a set high temperature through the thermal insulation heating device 16 . Fastening bolts 26 and magnetic drive device 12 seal the reactor. The magnetic driving device 12 provides a driving force to rotate the rotat...
