Electromagnetic type fused salt evaporating method

Abstract

The invention provides an electromagnetic type fused salt evaporating method applied to an electromagnetic type fused salt evaporator. The electromagnetic type fused salt evaporator comprises an evaporation cavity, a fused salt evaporation body and an electromagnetic induction coil. The electromagnetic induction coil surrounds the fused salt evaporation body. A fused salt evaporation pipe is arranged in the fused salt evaporation body. The electromagnetic type fused salt evaporating method comprises the following steps that S1, a gas compression refrigerator is started so that refrigerating gas can circulate in a gas flow channel; S2, the electromagnetic induction coil is used for preheating the fused salt evaporation pipe until the temperature higher than 1000 DEG C; S3, fused salt is poured into a fused salt liquid inlet of the fused salt evaporation pipe, and fused salt liquid is recovered from a fused salt liquid outlet. In the refrigerating step S1, by means of the electromagnetic induction coil with the gas flow channel and the gas compression refrigerator, the electromagnetic type fused salt evaporating method has the advantages that the refrigerating effect is stable, and dirt deposition is avoided.

Description

Technical field [0001] The invention relates to the field of molten salt distillation, in particular to an electromagnetic molten salt evaporation method. Background technique [0002] At present, the heating of molten salt or molten salt furnace is mainly used in industrial heat transfer systems. The required temperature conditions are relatively mild, generally around several hundred degrees Celsius. The heating means can be coal-fired heating, resistance furnace heating, etc. Among them, coal-fired heating has high energy consumption, resistance furnace heating is slow, and heating efficiency is low. [0003] The molten salt carrier in molten salt reactors is usually fluorine salt, which is very corrosive, and it is more corrosive when exposed to water, and it is easy to corrode equipment. For the nuclear power industry, the safety requirements are strict and it is necessary to eliminate all hidden dangers, so the equipment environment involving molten salt is required to be an...
