Traditional seawater desulfurizing process can be divided into flue gas system, the row's of confession sea water service system, SO
2Absorption system, seawater quality recovery system, measurement and control system.SO wherein
2The capital equipment of absorption system is the absorption tower, and packed bed is equipped with in inside, and the seawater that is sprayed into by tower top passes through packed bed and fully contacted by the flue gas that gets into (flowing) at the bottom of the tower from bottom to top, is convenient to SO
2Abundant absorption.Demister is equipped with in the absorption tower outlet, removes the molecules such as droplet in the flue gas, can reduce fouling and obstruction in GGH and back equipment.
Although traditional seawater desulfurizing process at home and abroad is applied,, except this technology only was fit to the abundant zone of seawater resources, its desulfuration efficiency was low, the seawater consumption is big, and filler need regularly clean and add.At present, mostly the filler that uses in China's seawater desulfurizing and absorption tower is external import, costs an arm and a leg, and system operation cost is high.Therefore, development of new sea water desulfuration technology is very necessary.
Summary of the invention
