A provided comprehensive spectrometer comprises a sample cell for holding a to-be detected sample, and a light source and a detector respectively at two opposite sides of the sample cell, and also comprises a heating furnace used for heating the to-be detected sample, and a protection insulation box disposed above the heating furnace; the heating furnace possesses a function channel which vertically extends downwards from the top and is used for picking and placing of the sample cell, and a transversely-extending light-passing channel through which a light beam passes; the protection insulation box is communicated with the function channel of the heating furnace via an opening on the bottom plate; and the protection insulation box provides operation spaces for preparing the to-be detected sample, putting the to-be detected sample into the sample cell and sending the sample cell to the heating furnace. According to the comprehensive spectrometer, the protection insulation box is creatively connected with the heating furnace, the accuracy of measured data is guaranteed, safety protection is provided for operators, and the provided comprehensive spectrometer possesses protection facility, and is capable of determining infrared absorption and fluorescence emission of high-temperature molten salt with relatively strong corrosivity at a high temperature.
Description
technical field [0001] The invention relates to the technical field of instruments and devices, in particular to a comprehensive spectrometer. Background technique [0002] Molten salt has been widely used in the fields of solar energy and nuclear energy due to its excellent thermophysical properties and heat transfer and storage properties. Lithium fluorine beryllium molten salt is selected as the primary circuit coolant of the molten salt reactor (one of the six fourth-generation reactors) due to its excellent heat transfer performance and neutron characteristics, and uranium tetrafluoride is used as the main component of the molten salt reactor fuel. Its chemical behavior in the main coolant fluorine lithium beryllium molten salt, especially its coordination structure is very important, which plays a key role in its solubility in molten salt. One of the advantages of the molten salt reactor is that its nuclear fuel is in a liquid state. If uranium tetrafluoride performs ...
