The invention provides a multifunctional high-temperature furnace. The multifunctional high-temperature furnace comprises a tubular high-temperature furnace, wherein the tubular high-temperature furnace comprises a furnace body and a furnace tube, an electric heating layer is arranged on the inner wall of the furnace body, and the furnace tube penetrates through the furnace body and is located in the electric heating layer. A first sealing flange is arranged at one end of the furnace tube, a second sealing flange is arranged at the other end of the furnace tube, and a feeding port is formed in the first sealing flange and connected with a feeding device. A gas collecting device for collecting gas is arranged on the second sealing flange. An electronic scale is arranged on the tubular high-temperature furnace, and an air vent is formed in the second sealing flange and connected with a vacuum apparatus. An air inlet is formed in the first sealing flange and connected with an air inlet device. By means of the technical scheme, long-time and stable heat reaction of materials in the furnace tube can be achieved, the gas environment for material reaction can be adjusted, quality change in the reaction process can be measured, and analysis effect of material thermal chemical reaction can be improved.
Description
technical field [0001] The invention relates to a high-temperature furnace, in particular to a multifunctional high-temperature furnace for thermochemical analysis of materials. Background technique [0002] In industries such as coal, chemical industry, electric power, metallurgy, and environmental protection, it is necessary to perform thermochemical analysis on materials such as coal, such as pyrolysis, incineration, gasification, and sintering. Among them, when performing thermochemical analysis on these materials, the materials are usually put into a high-temperature furnace for high-temperature heating, and then the gas and solid produced after heating are analyzed for physical and chemical properties, and then the thermochemical properties of the materials are obtained. Provide references. [0003] At present, the high-temperature furnace for high-temperature heating of materials usually adopts an ordinary high-temperature heating furnace. The material that needs to ...
