Maturation, raw material are easy to get, technology is simple, take up an area of less, reliable, advantages such as operating cost is lower, non-secondary pollution and the sea water desulfuration technology possesses skills.The seashore line length of China, coastal area economy are flourishing, and environmental protection requirement is strict.Engineerings such as coastal newly-built, reorganization and expansion power plant, steel plant are more, so the sea water desulfuration technology has wide practical use.
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

The present invention realizes through following technical proposals:
A kind of seawater compound desulfurizer; Comprise the absorption tower; Its characteristics are to be disposed with in the absorption tower primary atomization desulfurization zone, bracing frame, secondary liquid film desulfurization zone, seawater distributor from bottom to top, remove the fog-zone; The top on said absorption tower is provided with exhanst gas outlet, and bottom, said absorption tower is provided with smoke inlet, and said primary atomization desulfurization zone, seawater distributor are connected with salt water system.
Said primary atomization desulfurization zone is made up of the atomizer of a plurality of array distribution.
Said secondary liquid film desulfurization zone is made up of the packing layer that is deposited on the bracing frame.Said packing layer is that the unordered accumulation of the irregular collapsible or spiral PVC plastics of multilayer constitutes.
The said fog-zone of removing is made up of demister.The structure of said seawater distributor is identical with the structure of primary atomization desulfurization zone.
Compared with prior art, the invention has the beneficial effects as follows:
(1) primary atomization desulfurization zone and secondary liquid film desulfurization zone are realized the seawater composite desulfate, more effectively remove the SO in the flue gas
2, the consumption of saving seawater and filler, water-saving and electricity-saving reduces desulphurization cost.
(2) the primary atomization desulfurization zone is made up of atomizer efficiently, and seawater is atomized into fine particle, makes fully to mix with flue gas, reacts more abundant, effectively utilizes the space, absorption tower.
(3) secondary liquid film desulfurization zone provides reaction surface by filler on the one hand, makes the abundant haptoreaction of flue gas and seawater, and for for the flue gas behind the once desulfurization, packing layer also possesses except that fog effect on the other hand.
(4) owing to adopt the seawater composite desulfate, make the use amount of seawater and filler reduce, can reduce the thickness of secondary liquid film desulfurization zone, and then reduce the height on absorption tower.
(5) seawater distributor provides seawater to secondary liquid film desulfurization zone on the one hand, can also spray desulfurization to flue gas once more on the other hand.
(6) demister is further removed the molecules such as droplet in the flue gas, reduces fouling and obstruction in the equipment of GGH and back, has reduced maintenance cost.
This patent adopts simple and easy to do technological means, has good effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Following specific embodiments of the invention is done further detailed explanation, but embodiment of the present invention is not limited thereto.
As shown in Figure 1.Seawater compound desulfurizer of the present invention; Be to be disposed with in the absorption tower primary atomization desulfurization zone 2, bracing frame 3, secondary liquid film desulfurization zone 4, seawater distributor 5 from bottom to top, remove fog-zone 6; The top on said absorption tower is provided with exhanst gas outlet 7; Bottom, said absorption tower is provided with smoke inlet 1, and said primary atomization desulfurization zone 2, seawater distributor 5 are connected with salt water system.
