Each set of flow retarding mechanism 52 includes a coherent main shaft 521, a plurality of flow retarding ring plates 522, and a plurality of flow breaking ring plates 523, where the coherent main shaft 521, the flow retarding ring plates 522, and the flow breaking ring plates 523 may all be made of silicon carbide, and all the flow retarding ring plates 522 and all the flow breaking ring plates 523 are integrally formed on the coherent main shaft 521, and in this embodiment, the outer diameter of the flow breaking ring plates 523 is larger than the outer diameter of the flow retarding ring plates 522.
Referring to fig. 3 and 4, all of the flow-retarding ring plates 522 and all of the flow-stopping ring plates 523 are spaced apart and equally spaced along the length of the consecutive main shafts 521, and one flow-stopping ring plate 523 is located between two adjacent flow-retarding ring plates 522. After the heat-conducting fluid enters the inner cavity of the temperature-through channel 511, the flow-retarding annular plates 522 and the flow-stopping annular plates 523 with different outer diameter sizes sequentially block the heat-conducting fluid to enable the flow speed of the heat-conducting fluid in the inner cavity of the temperature-through channel 511 to be greatly reduced, and accordingly, the heat-conducting efficiency of the heat-insulating block 51 to the inner cavity of the communication channel 512 through the heat-conducting fluid is greatly improved, so that a stable heated space is easier to form in the inner cavity of the communication channel 512 and is in a heat-insulating constant-temperature state for a long time.

The gas enters the inner cavity of the gas guide pipeline 21, and is rapidly conducted to the inner cavity of the gas guide pipeline 21 through the communication channel 512, so that the gas in the inner cavity of the gas guide pipeline 21 is heated uniformly and stably, and the effect of heating the gas is achieved. Meanwhile, the air guide pipeline 21 has the characteristics of high pressure resistance and corrosion resistance, so that the air guide pipeline 21 is not easy to damage, and the heating sustainability and the stability in the air re-guide pipeline 21 are ensured. The temperature of the inner cavity of the communicating channel 512 is uniformly and steadily increased due to the continuous flow of the heat-conducting fluid, so that the phenomenon of severe reaction of the gas caused by local sudden temperature increase can be reduced, and the heating sustainability and stability in the gas re-introducing pipeline 21 are further ensured.
The temperature measuring part 32 measures the temperature of the heated gas in the inner cavity of the gas guide pipeline 21, and the process enables the gas heating and the temperature measurement to be carried out synchronously, so that the temperature difference phenomenon generated by the fact that the temperature is measured after the gas heating is effectively reduced, and the accuracy of the temperature measuring part 32 in measuring the temperature of the heated gas is ensured.

Meanwhile, the air guide pipeline 21 is convenient for operators to detach quickly, so that the air guide pipeline 21 used for a long time is maintained and replaced, and the air guide pipeline 21 is beneficial to guaranteeing the sustainability and stability of heating of air in the inner cavity of the air guide pipeline 21.

After the air guide duct 21 is used for a long time, an operator can screw the locking nut 723 to disengage the locking nut 723 from the end screw 722. Then, the operator pulls the air guide duct 21 to separate the air guide duct 21 from the heat conductive tube 71, so that the operator maintains and renews the air guide duct 21 for a long time to ensure the durability and stability of the subsequent heating of the air in the air guide duct 21.
