[0021] In order to enable the carbon fiber high-temperature carbonization device to optimize the movement route of the raw wire, improve the carbonization time, and increase the carbonization quality, as shown in the attached Figure 1-6As shown in the figure, the present application adopts the following structure.

[0023] In order to enable the carbon fiber high-temperature carbonization device to have the effect of recovering waste heat and reducing resource waste and to enable the carbon fiber high-temperature carbonization device to have the effect of improving the waste gas treatment effect and preventing environmental pollution, as shown in the appendix Figure 1-10As shown in the figure, the present application adopts the following structure. Through the coordinated setting of the air collection chamber 18, fan blades 22, diversion pipes 23, heating tank 25, spiral diversion plates 26, liquid storage chamber 27, small water pump 30, connecting pipes 31 and return pipes 28, treatment frame 24, filter frame 33, fine molecule filter screen 34 and activated carbon adsorption plate 35, during the use process, when the advancing distance of the original wire is adjusted, the adjustment frame 2 is inserted into the interior of the body 1. Subsequently, the interior of the body 1 is heated by the heating pipe 40 to carbonize the raw filaments in the adjustment frame 2.

At the same time, through the operation of the small water pump 30, in cooperation with the connecting pipes 31 and the return pipes 28, the liquid in the heating tank 25 and the liquid storage chamber 27 is circulated, enabling the heat to be gradually transferred to the upper liquid storage chamber 27 to effectively complete the liquid heat cycle, achieving waste heat recovery while insulating the body 1, improving the carbonization effect while reducing resource waste. After the waste heat recovery of the gas in the diversion pipes 23 is completed, it enters the treatment frame 24. The gas first enters the corresponding waste gas treatment liquid previously added from the outside to fuse and decompose the harmful substances in the gas. Subsequently, after being treated by the fine molecule filter screen 34 and the activated carbon adsorption plate 35, the gas is discharged from the exhaust holes 37, thereby enabling the carbon fiber high-temperature carbonization device to have the effect of waste heat recovery and reducing resource waste, and enabling the carbon fiber high-temperature carbonization device to have the effect of improving the waste gas treatment effect and preventing environmental pollution.
