连续管式结晶器研究进展

Development of continuous tubular crystallizer

结晶是大多数化工生产过程中必不可缺的步骤。目前,大部分结晶过程采用间歇结晶,但间歇结晶的生产模式存在批次间差异、生产成本过高等缺点。因此,连续结晶作为新的结晶模式逐渐成为研究的重点。其中,连续管式结晶器具有较窄的停留时间分布和较高的生产效率等优势,已广泛应用于工业结晶。针对连续管式结晶器研究现状进行了详细介绍,总结了管式结晶器普遍存在的问题和解决方法,并介绍了辅助设备和技术在连续管式结晶器中的应用。最后,总结了管式结晶器的进一步发展方向。

Crystallization is indispensable in the most production of chemical industry. At present, batch crystallization is widely applied in most crystallization processes. However, it has some shortcomings such as inconsistent product quality and high cost. As another crystallization mode, continuous crystallization has gradually become a research priority. The continuous tubular crystallization process has been widely applied in industrial crystallization due to the advantages of narrow residence time and high efficiency. In this work, the development of continuous tubular crystallizer is introduced in detail, and the common problems and solutions of tubular crystallizer are summarized. In addition, the applications of assisted equipment and technology in the continuous tubular crystallizer are also discussed. Finally, the further development of tubular crystallizer is summarized.
