热电厂烟气脱硫技术初探

Preliminary Approach on Flue Gas Desulfurization Technology in Thermal Power Station

火电厂排放的SO2严重地危害着人类的生存环境,为此,国家重新修订了《火电厂大气污染物排放标准》,强制要求对火电厂排放的烟气,要安装烟气脱硫装置来进行控制。笔者以氧化铝厂配套建设的热电厂锅炉烟气治理为例,分析、比较了几种治理措施的特点,提出了适合的烟气脱硫方法。

As SO2 emission from the fossil power plant has seriously endangered the people＇s living environment, the State modified the ＂Emission Standard of Air Pollutants for Fossil Power Plant＂ in order to enhance control over fossil power plants＇ SO2 emission, for which installation of the fume desulfurization device is also compulsorily required. Based on different solutions adopted for dealing with boiler flue gas emitting from the thermal plant in an aluminum smelter, this paper makes comparative analysis on semi -dry desulfurization technological process and its effect in actual application. Proper solutions for fume deslfurization of thermal plant, which has been equipped by an aluminum smelter, are proposed herein.
