本研究对中药生产过程中传统浓缩工段的能耗进行了分析研究,并采用机械蒸汽压缩技术(mechanical vapor recompression,MVR)对传统浓缩工艺进行改进,以实现浓缩过程的能量循环利用。以此为基础采用化工仿真软件Aspen Plus对某中药厂的甘草多糖水溶液浓缩过程进行仿真模拟,详细考察了MVR对中药浓缩过程的节能优势以及其对浓缩过程稳定性的影响。在此基础上,对MVR技术改造后的浓缩工段的压缩机压缩比、进料流量、浓缩倍数以及加热蒸汽节约率和成本节约率进行了仿真模拟和分析研究。通过响应面法,观察到压缩机的压缩比对MVR技术的生产过程具有重要的影响,是浓缩过程节能和降低生产成本的关键因素,为MVR技术在中药生产过程的应用提供了理论支持。 In this study, the energy consumption of traditional concentrating section in the process of traditional Chinese medicine production was analyzed and analyzed, and the traditional concentration process was modified by mechanical vapor recompression (MVR) to realize the energy recycling in the concentration process. Based on this, the chemical simulation software Aspen Plus was used to simulate the concentration process of glycyrrhiza polysaccharides aqueous solution of a traditional Chinese medicine factory. The energy saving advantages of MVR on the concentration process of traditional Chinese medicine and its influence on the stability of the concentration process were investigated in detail. On this basis, the compressor compression ratio, feed flow, concentration ratio, heating steam saving rate and cost saving ratio of the concentrating section after the revamping of MVR technology are simulated and analyzed. Through the response surface method, it is observed that the compressor’s compression ratio has an important influence on the production process of MVR technology, which is the key factor to save energy and reduce the production cost in the concentration process, and provides theoretical support for the application of MVR technology in the production process of traditional Chinese medicine.
