湿法脱硫系统事故烟气急冷数值模拟研究

对脱硫系统事故工况下急冷装置下游烟气的流场及温度场分布进行了数值模拟研究和分析，并提出了基于原始喷雾系统布置方案的一种优化方案。该方案在能满足设计要求的前提下，最大限度的减少了喷嘴数量和水耗。在事故急冷装置实际工程设计及应用上，具有一定的理论指导意义。

Numerical simulation study on emergency flue gas quenching in wet-FGD system

The flow and temperature distribution of flue gas downstream of emergency quench device in wet -FGD system have been studied and analyzed by numerical simulation. On the basis of original spray system,a new optimized scheme has been put forward. On the premise of meeting the requirement of design,the opti-mized scheme can reduce the quantity and water cost in the maximum limit. And then,there is a very important theoretical guide meaning to the practical engineering design and application of emergency quench device.
