FGD取消GGH对区域环境的影响研究——以洛河电厂为例

STUDY ON THE EFFECT OF REGIONAL ENVIRONMENTAL FOR UNINSTALLING GGH FROM FGD SYSTEM

介绍了湿法烟气脱硫系统取消气气换热器的国内外现状,阐述FGD系统设置GGH的负面影响,在对洛河电厂大气污染源监测的基础上,预测FGD系统中取消GGH装置对研究区域大气污染物扩散的影响。结果表明:在静风条件下,FGD系统取消GGH装置大气污染物的扩散对关心点的影响不甚明显;污染源对各关心点日均浓度贡献最大的为上窑镇;不同气候条件下,FGD系统取消GGH装置对研究区域环境空气质量贡献值仅是很小一部分。

The thesis introduces status of domestic and overseas on canceling the GGH（gas to gas heater） device from FGD（flue gas desulfurization） system,it describe the negative influence of installing the GGH device from FGD system,based on monitoring of air pollution sources from Luohe Power Plant,the effects on atmospheric pollutant dispersion is forecasted and after canceling the GGH device from FGD system from.The results are as follows： Under static wind conditions,mass of concentration of sensitive points changes little between setting and canceling the GGH device from FGD system;typical day average concentration of Shangyao Town is the largest for sensitive points of atmosphere pollution sources;Under different weather conditions,mass of concentration of environmental air quality changes little on canceling the GGH device from FGD system.
