Description

Technical Field

[0001] The utility model relates to a graphitization furnace, in particular to an energy-saving and high-efficiency graphitization furnace. Background Art

[0002] A graphitization furnace is a high-temperature treatment device that performs high-temperature treatment on specific materials so that the specific materials are graphitized in a carbon environment. The heating temperature can reach two thousand to three thousand degrees Celsius. The Chinese utility model patent with application number 202220903512.9 provides a graphitization furnace with energy-saving waste heat recovery. The device can enable the heat exchange medium to recover the residual heat in the gas and the high-temperature furnace to achieve energy saving and environmental protection. However, when the device causes the high-temperature gas flow to drive the stirring element to rotate, the high-temperature gas will reduce the flow rate in the gas channel. Although the heat exchange efficiency is improved, it is not conducive to the timely discharge of the high-temperature gas, which reduces the cooling efficiency of the graphitization furnace and highlights the shortcomings of the prior art.
