300MW机组湿法烟气脱硫(WFGD)吸收塔内气液流场模拟
摘要
利用Fluent软件平台
对某300MW机组WFGD吸收塔内气液两相流场进行了数值模拟
着重考察喷淋浆液滴对塔内烟气流场的影响。结果表明
浆液滴喷淋后对烟气流场具有整合作用
模拟的塔内平均压降(850Pa)与实际现场测试数据的平均压降(909Pa)较为吻合。
Abstract
Using Fluent software platform
the gas-liquid two-phase flow field in absorption tower of wet flue gas desulfuration (WFGD) has been simulated
the influence of spray slurry droplet upon the flue gas flow field in the said tower being emphatically investigated. The results show that the slurry droplet after spraying has conforming effect on the flue gas flow field
the average pressure drop (850 Pa) in the simulated tower tallies comparatively well with the measured average pressure drop (about 909 Pa) in the field.
