脱硫废水零排放系统关键参数数值模拟研究
Numerical Simulation of Key Parameters of Zero Discharge System for WFGD Wastewater
摘要
Abstract
The evaporation technology of WFGD wastewater in the flue gas before it enters ESP is studied by numerical simulation. The impacts of the six parameters on droplet residence time and evaporation distance are investigated, i.e., droplet size, flue gas temperature, flue gas velocity, wastewater volume, jet velocity and jet angle of wastewater. The results show that the higher of the flue gas temperature, the smaller of the droplet size and the injection amount, the less residence time of the droplet will last. With the increase of flue gas velocity, injection velocity and injection angle, the residence time tends to decrease first and then rise afterwards. The research results can provide support for project decision-making process and design optimization.关键词
