[0037] The reaction furnace mechanism 1 is used to provide a high-temperature reaction environment for graphite processing to promote physical or chemical transformation of graphite. The reaction furnace mechanism 1 includes a reaction furnace 101. The reaction furnace 101 is provided with a furnace wall 1011 inside.

The pressure detector 106 uses highly sensitive pressure sensing technology to accurately measure the pressure value in the reactor 101. It can monitor the pressure changes in the reaction process in real time. When the pressure exceeds the set safety range, it will issue an alarm signal in time to remind the operator to take decompression or other safety measures to prevent dangerous accidents such as explosions caused by excessive pressure.

[0044] Working principle: First, the reaction furnace mechanism 1 is started, and the heating tube 1012 provided on the internal furnace wall 1011 thereof starts to work, and heats the placement tank 102, thereby creating a high-temperature reaction environment for graphite processing. Before the reaction starts, the nitrogen tank 501 in the gas supply mechanism 5 first introduces argon or nitrogen into the furnace wall 1011, and continuously introduces it at a high flow rate for 5-15 minutes. By detecting indicators such as the oxygen content or air pressure in the reaction furnace 101, it is ensured that the air in the reaction furnace 101 is evacuated, and impurity gases such as oxygen and water vapor are removed to create a stable inert atmosphere. While the protective gas is continuously introduced, the hydrogen tank 502 then introduces hydrogen. Hydrogen is used as a carrier gas and continuously introduced for 2-5 minutes at a flow rate lower than that of the protective gas, to help It helps to dilute the carbon source gas 503 to be introduced later, so that it is more evenly distributed in the reactor 101, and at the same time removes impurities such as oxides on the surface of the substrate, providing a good attachment site for graphene growth. After nitrogen and hydrogen are stably introduced for a period of time, the carbon source gas tank such as methane begins to introduce carbon source gas 503, and its flow rate is accurately controlled according to factors such as the size of the reactor 101, the type of substrate and the required graphene quality. The introduction time is determined according to the graphene growth thickness requirements, which may vary from several minutes to tens of minutes. The carbon source gas 503 decomposes under the action of high temperature and catalyst, and carbon atoms are deposited on the surface of the substrate to form graphene. At the same time, in the test component on the top of the reactor 101, the temperature detector 104 monitors in real time The temperature in the reactor 101, the gas detector 105 detects the gas composition and concentration, and the pressure detector 106 monitors the pressure change, so as to timely feedback the reaction situation and make adjustments. When the reaction is finished or the temperature needs to be lowered, the secondary cooling mechanism 6 is started, and the cooling liquid in the liquid storage tank 601 flows to the annular pipe 605 through the pipeline under the action of the liquid delivery pump 602, and the high-temperature products or equipment parts coming out of the reactor 101 are initially cooled. After that, the cooling liquid is circulated under the cooperation of the liquid pump 603 and the one-way valve 604. The primary cooling mechanism 3 then works, and the water in the water tank 301, driven by the water pump 304, first enters the cooling cylinder 306 and the internal serpentine cooling pipe 305, and flows out of the secondary cooling mechanism 6 The cooling medium is cooled and then flows back to the water tank 301 to complete the cooling cycle. The remaining waste gas after the reaction enters the waste gas treatment mechanism 4. The waste gas is first collected by the air intake box 401, and then under the control of the control box 404, it enters the combustion box 402 through the waste gas pipe 406 and the one-way valve 405, and finally is burned through the combustion tube 403 to purify the waste gas. In addition, in the lifting and rotating assembly on the top of the furnace cover 103, the handle 107 can facilitate the operator to open and close the furnace cover 103, and the hook ring 108 can be used to hang tools or auxiliary components related to the reaction process. The mounting frames 2 on the four sides of the reactor 101 play a role in stably supporting the reactor mechanism 1 to ensure the stability of the entire device during operation.
