摘要
讨论了湿烟气直接排放带来的3个环境问题:抬升高度低,地面污染浓度较大;水汽凝结造成白烟;凝结水对局地气候的影响。通过简化计算,给出了某些环境和排放条件下抬升高度、地面最大浓度、白烟长度和凝结水量的定量估算,对进行湿烟气直接排放可行性研究的人员有重要参考意义。
Three environmental problems:pollution,vapor conden sa tion and white plume in unheated scrubbed plume are discussed,some calculated sa mples are given.It is found that the ground maximum concentration will probablyincrease 40% sometimes compared with that produced by reheated plume.The lengthof condensed plume(white plume)varies with ambient temperature,relative humidit y and plume temperature from a few tens of meters to a few hundred of meters.Itis very sensitive to the variation of environmental relative humidity.
