Description

High-temperature dynamic melting method experimental device

Technical Field

The utility model belongs to the field of experimental equipment, and particularly relates to a high-temperature dynamic fusion method experimental device.

Background

At present, mixed molten salt still has the current situations of high melting point and relatively poor thermal stability as a heat transfer and storage medium and still cannot meet the diversified requirements of large-scale energy storage on the molten salt medium. With the rapid development of solar thermal power generation technology and the continuous improvement of large-scale energy storage demand, the development of novel mixed molten salt with higher stability, lower melting point and better heat transfer and storage characteristics becomes a main direction for researching molten salt heat storage. In the aspect of strengthening molten salt thermophysical property research, a main approach is to mix a nano material and molten salt to prepare a nano composite material (nano molten salt) so as to strengthen key thermophysical property parameters of the molten salt. Currently, the research on preparing the nano molten salt by an aqueous solution method is the most. The high-temperature melting method, the high-temperature decomposition method and the ball milling method are production methods which have appeared in recent years. The difference of the preparation method can influence the thermal physical property of the mixed nano molten salt. In a comprehensive view, the preparation process of the high-temperature decomposition method involves complex chemical reaction and has certain potential safety hazard; the fused salt material prepared by the water solution method has better thermal physical property than that of the ball milling method; the high-temperature melting method is characterized in that nanoparticles are directly added into a molten salt melt, and the nano molten salt is prepared through static melting or dynamic stirring, so that the obtained molten salt is better in thermal stability, and compared with an aqueous solution method, the high-temperature melting method is simpler in process and lower in energy consumption. Therefore, the development of a high-efficiency low-cost nano molten salt preparation method and an optimized material preparation device have very important significance.

The high temperature dynamic melting method adopted in the laboratory at present is generally that a round-bottom flask is placed in a magnetic stirring electric heating sleeve, and substances in the round-bottom flask are uniformly mixed by utilizing a magnetic stirrer in the heating process. However, this method has the following technical drawbacks. Firstly, the method is only suitable for the material dosage of more than 50mL, because the common minimum specification of the current commercially available magnetic stirring electric heating jacket is generally 100mL, and the specification of the round-bottom flask matched with the minimum specification is 100mL, the material dosage in the high-temperature dynamic melting reaction can not be too small, and the raw material dosage of a single reaction is increased. If a round-bottom flask with smaller specification is adopted, the distance between the outer wall of the flask and the inner wall of the electric heating jacket is too large, the heating is slow and uneven, the heating efficiency is reduced, and the service life of the electric heating jacket is influenced. Secondly, the heating temperature of the high-temperature dynamic melting method is usually higher than 200 ℃, and when the temperature is higher than 200 ℃, the conventional polytetrafluoroethylene magnetic stirrer can generate a demagnetizing phenomenon, so that the dynamic melting stirring effect cannot be realized, and the constant-temperature magnetic stirring electric heating sleeve loses the synchronous stirring function at high temperature (higher than 200 ℃). Although a few commercial products provide high-temperature-resistant glass magnetic stirrers, the glass magnetic stirrers are generally large in size (about 20mm in length) and are not suitable for preparation of tiny materials. In conclusion, a high-temperature dynamic fusion method experimental device suitable for micro preparation of nano molten salt is lacked at present.
