Electromagnetic induction heating device for obtaining high-temperature rare gas

Abstract

An electromagnetic induction heating device for obtaining high-temperature rare gas comprises a metal heating pipe, an electromagnetic induction coil, an electromagnetic induction heating power supply, a flange, a gasket, a containment cylinder, a heat insulation layer, a refractory filling material, an inlet and outlet pipeline, a cover plate and graphite filler. Rare gas enters the metal heatingpipe from the inlet pipeline, and the metal heating pipe is heated to a high-temperature state under the action of induction electric heating, so that the rare gas in the metal heating pipe is heated, and then the high-temperature rare gas flows out from the outlet pipeline. Inert gas atmosphere is formed in the containment barrel, so that the metal heating pipe is prevented from being oxidized at high temperature; the containment cylinder is made of a high-temperature-resistant material, so that the temperature of each part of the heating device is lower than a corresponding temperature limit value; the whole heating device is connected through a flange, and the defect that a metal heating pipe is made of high-temperature-resistant special materials and is not easy to weld is overcome. The heating device can heat gas to a higher temperature, can stably and safely operate for a long time, and can meet the requirements of the current processing technology at the same time.

AI Technical Summary

Problems solved by technology

However, the current heating device for high-temperature gas has great deficiencies and is difficult to realize, which is mainly affected by the high-temperature resistance of the material.

The processing and welding performance of high-temperature-resistant special metals is worse than that of conventional metal materials, which leads to strict restrictions on processing and assembly during its application

Conventional gas heating methods and scheme designs are difficult to directly extend to the application of high temperature gas heating
