Abstract

An inserted intermediate frequency fused salt heater comprises a tubular heating tube fixed seat, a plurality of heating tubes welded and fixed at the lower portion of the tubular heating tube fixed seat, a fixed seat flange welded at the upper portion of the tubular heating tube fixed seat, leads arranged in heating tubes, a medium frequency transformer and a medium-frequency power supply, wherein the leads are tightly welded with the bottom ends of the heating tubes, the leads are connected with secondary coils of the medium frequency transformer, the primary coil of the medium frequency transformer is connected with the medium-frequency power supply, and the secondary coil of the medium frequency transformer inducts a frequency high current in a low voltage; the leads, the heating tubes, the heating tube fixed seat and the secondary common end of the medium frequency transformer are connected to form a loop, each lead is connected with the secondary coil end, eddy is formed on the tube bodies of the heating tubes to perform rapid heating, and the intermediate frequency intermediate frequency is employed to allow the heating tube to directly heat in the fused salt liquid. The inserted intermediate frequency fused salt heater is high in heating efficiency, has no potential safety hazards of damaging people caused by electric leakage, and is long in service life, simple in structure, low in cost, convenient to maintain and very safe and reliable in usage.

Description

technical field [0001] This patent relates to the technical field of molten salt energy storage, in particular to a plug-in intermediate frequency molten salt heater. Background technique [0002] At present, molten salt energy storage is still an emerging topic. The molten salt energy storage technology imported from abroad uses molten salt pump circulation and molten salt heating furnace heating. The heating generally adopts dense electric heating tubes and natural gas furnace combustion heating methods, and the structure is complex. , The heating efficiency is low, and most of the equipment accessories need to be imported at present, and the cost is expensive. Contents of the invention [0003] The purpose of this patent is to provide a plug-in intermediate frequency molten salt heating system for the current molten salt energy storage system; device. [0004] The technical solution adopted by this patent to solve its technical problems is: by the tubular heating tube...
