脱硫废水烟道喷雾蒸发过程的数值模拟
, PP. 31-36
Keywords: 脱硫废水,烟道,烟气,雾化,蒸发,液滴直径,温度,速度
Abstract:
针对脱硫废水处理问题，建立了烟道内气液两相流动、传热传质和雾化液滴蒸发的数学模型,并利用该模型对某330mw机组锅炉空气预热器后接烟道内雾化液滴的蒸发过程进行模拟研究,分析了烟气温度、雾化液滴初始直径、初始温度和初始速度对其完全蒸发时间的影响。结果表明:烟气温度越高,雾化液滴完全蒸发所需要的时间越短；雾化液滴初始直径越大,其完全蒸发时间越长；雾化液滴初始速度和初始温度对其完全蒸发时间的影响不大；雾化液滴完全蒸发过程中,烟气温度最佳值为134℃及以上,雾化液滴初始直径最佳值为10～60μm。该结果可为脱硫废水烟道蒸发处理系统的设计及运行优化提供参考。
