新型多级液幕喷雾洗涤式烟气脱硫技术的试验研究

Experimental Study on Flue Gas Desulfurizaiton Technology by New Multi-stage Liquid Curtain Spray-abstersion Method

针对燃煤锅炉烟气中SO2 排放的特点 ,从反应机理着手 ,制定了相应的设计脱硫装置的原则 ,研制了一种新型多级液幕喷雾洗涤式脱硫塔 ,并对脱硫装置进行了多工况试验研究 .通过研究发现 ,燃烧产生的含有SO2 的烟气在经过脱硫塔后其排放得到了有效控制 ,液气比、SO2 浓度、Ca(OH) 2 浓度及反应温度的变化对脱硫效率产生了不同的影响 .

In view of the characteristics of SO 2 emission from the coal fueled boilers' flue gas, the rule of designing desulfurization device is instituted on the basis of chemical reaction mechanism, thus a new multi stage liquid curtain spray abstersion tower is designed for studying the rules among sorbent concentration, ratio of liquid to gas and SO 2 concentration by simulating a certain sulphur content flue gas.
