AI Technical Summary
Traditional evaporation crystallization equipment suffers from uneven heat distribution during the low-temperature heating stage. Localized high temperatures can easily disrupt the crystallization conditions of nickel sulfate, and the equipment lacks a convenient and accurate steam monitoring structure, making it difficult to adjust experimental parameters in real time.
The gas supply and heating assembly employs an inverted bell-shaped combustion tube and a ring-shaped converging hood that is narrow at the top and wide at the bottom. Combined with a steam testing assembly designed with a swing arm and a limiting frame, it achieves precise low-temperature heating and steam characteristic monitoring, ensuring the stability of the crystallization process and the accuracy of parameter adjustments.
This method enables precise low-temperature heating of nickel sulfate solution, preventing high-temperature decomposition, ensuring the stability of the crystallization process and the quality of the crystals, while facilitating the efficient collection and analysis of vapor components, providing a reliable basis for adjusting experimental parameters.
