Traditional seawater desulfurizing process can be divided into flue gas system, supply and discharge sea water service system, SO
2absorption system, seawater quality recovery system, measurement and control system.Wherein SO
2the capital equipment of absorption system is absorption tower, and packed bed is equipped with in inside, and the seawater being sprayed into by tower top passes through packed bed and fully contacted by the flue gas that enters (flowing) at the bottom of tower from bottom to top, is convenient to SO
2abundant absorption.Demister is equipped with in absorption tower outlet, removes the molecules such as droplet in flue gas, can reduce in GGH and fouling and the obstruction in equipment below.
Although traditional seawater desulfurizing process is at home and abroad applied,, except this technique is only suitable for the abundant region of seawater resources, its desulfuration efficiency is low, seawater consumption is large, and filler need to regularly clean and add.At present, the filler using in China's seawater desulfurizing and absorption tower mostly is external import, expensive, and system operation cost is high.Therefore, development of new sea water desulfuration technology is very necessary.
