The heat pipe 706 is fixedly connected, and one end of the heat conducting pipe 706 is fixedly connected to the top of the return pipe 707. The bottom end of the return pipe 707 is arranged in the liquid storage tank 701.

[0031] The use method and advantages of the utility model: When the secondary oxygen supply device for the activated calcining kiln is in operation, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, oxygen can be released from the oxygen cylinder 303 into the oxygen supply pipe 402 through the first control valve 401. The pressure relief valve 403 can automatically release the pressure when the internal pressure of the oxygen supply pipe 402 is too high to prevent accidents caused by pressure accumulation. When oxygen enters the blades 503 set in the oxygen supply block 502 through the oxygen supply pipe 402, the oxygen passes through the blades 503 and enters the kiln in a swirling manner, increasing the contact area and mixing uniformity between oxygen and materials, thereby improving the efficiency of the combustion reaction. Before the oxygen enters the kiln, it is preheated through the heat pipe 706 to increase the temperature of the oxygen, enhance the heat exchange efficiency with the material, and ensure that the material combustion reaction is sufficient. After the oxygen supply is completed, the first control valve 401 can be closed, and it can be opened again when secondary oxygen supply is needed. The water pump 703 draws the coolant from the liquid storage tank 701 and sends it to the heat dissipation pipe 705 through the outlet pipe 704. Since the nozzle 603 supplies oxygen to the kiln at a high temperature, the coolant in the heat dissipation pipe 705 can absorb the heat of the oxygen supply block 502 to reduce its temperature. Then the coolant flows into the heat conduction pipe 706 through the second control valve 601, and the oxygen can be preheated while dissipating heat. When flame spraying occurs, by adjusting the second control valve 601, the coolant enters the nozzle 603 from the heat dissipation pipe 705 through the infusion pipe 602, and is sprayed out in a fan shape through the nozzle 603, which can increase the contact area between the coolant and the fire source, improve the fire extinguishing effect, and ensure the safety of the device.
