摘　　要：引言 海水烟气脱硫技术是利用天然海水的弱碱性吸收烟气中的SO2,达到净化烟气的目的。该技术在最近四十年内已在世界范围内众多大型电厂实现工业化应用,目前,多数海水烟气脱硫系统采用ABB（即ALSTOM）公司的Flakt-Hydro工艺,以脱硫塔作为主要的吸收设备,The absorption efficiency of stereoscopic and swirl parallel flow trays with different turning angles of blade（30°,45°,and 60°）were measured for single tray,double trays with co-rotating,and double trays with counter-rotating under different operating conditions in SO2-seawater testing system.The effects of turning angle of blade,liquid flux and liquid gas ratio on absorption efficiency were analyzed.The result showed that under the best operating condition for the seawater flue gas desulfurization,turning angle of blade 60°,liquid-gas ratio of 19.07 L·m-3 and double trays with counter-rotating,the absorption efficiency was 85%.The stereoscopic and swirl parallel flow tray presents good characteristics in a relatively wide range of operating condition because of its distinctive structure and concurrent flow in whole tower.
