氨法烟气脱硫工程中注氨的方式与方法

介绍了氨法脱硫在安徽金源热电厂的应用中,通过合理的注氨方式来提高脱硫效率,若注氨位置或注氨控制方式不当会引起出口烟气逸氨超标。该项目采用的新型氨法脱硫工艺是将氨分别注入吸收塔及铵盐氧化罐,并通过控制溶液的pH值来控制脱硫系统注氨量,并采用变频注氨泵使注氨量能快速、准确地根据入口二氧化硫含量调节注氨流量,使氨法脱硫能经济有效地运行。

THE WAYS AND METHODS OF AMMONIA INJECTION FOR AMMONIA FLUE GAS DESULFURIZATION SYSTEMS

It was introduced the application of ammonia desulfurization in Anhui Jinyuan Thermal Power Plant,ammonia was injected through reasonable means to increase the efficiency of desulfurization.The wrong location or the wrong control way of ammonia injection would cause ammonia in outlet flue gas over standard.The new ammonia desulfurization technology is that ammonia is injected separately into the tower and the oxidation tank,and by controlling the pH of ammonium salt solution to control the injection of ammo...
