摘要
针对黏胶短纤维生产中的高能耗问题,通过分析黏胶短纤维生产工序的能耗,提出了酸浴调配系统节能的可行性。探讨了毛雷尔模式和兰精模式两种酸浴调配系统的优缺点,通过技术进步和创新,合理设计了节能改进的酸浴调配生产流程。研究开发了新型闪蒸装置,利用多级闪蒸落酸调节酸浴的温度,以多级闪蒸一步提硝装置替代传统的结晶焙烧提硝。优化设计后的酸浴调配系统,综合先进的闪蒸技术,简化流程,节省投资。经工业化运行表明,能耗可降低23%,节能效果明显。
Aiming at high energy consumption in viscose staple fiber production, feasibility of energy-saving of spinbath preparation system was presented by analyzing energy consumption of each process in viscose staple fibre production. The advantages and disadvantages of two kinds of spinbath preparation system: Maurer model and Lenzing model were discussed. An improved energy-saving spinbath process was designed through technical progress and innovation. A new type of multi-stage flash evaporation device was developed. Multi-stage flash evaporation was used to regulate the temperature of circulated spinbath, and the traditional device with crystallization and calcination was replaced by a one-step device with multi-stage flash evaporation for extraction of anhydrous sodium sulfate. The advanced multi-stage flash evaporation simplified the process and saved investment. Industrialized operation showed that energy consumption could be reduced by 23% with obvious energy-saving.
