Description
Technical field
The utility model relates to a kind of desulfurizer that is provided with flue gas washing member, and being specifically related to ammonia is that raw material reclaims the flue gas desulfur device that oxysulfide is produced the sulphur ammonium from flue gas.
Background technology
The acidic gaseous harmful substance that contains in the flue gas, SO especially wherein
2It is the main source that forms acid rain.Employing ammonia is raw material, and the flue gas desulfurization product is an ammonium sulfate, is the very high chemical fertilizer of a kind of fertilizer efficiency.
But, the practical challenges that existing ammonia-process desulfurization technique faces jointly is exactly the flue gas behind the desulfurizing and purifying, or claim clean flue gas to carry the slurry drops that contains ammonium sulfate secretly, and under the disadvantageous condition of meteorological condition, under the lower situation of wind speed, the drop of slurries down can descend slowly and lightly near the chimney, scatter on the ground, on the equipment or on the building, become the spot of white, be called " sulphur ammonium misty rain " traditionally, or " sulphur ammonium rain ", influenced attractive in appearancely, even caused corrosion, become a new pollution problem.
The method of existing head it off generally all is foam removal or the defrosting function that increases flue gas, but effect is relatively poor.Therefore, if do not solve this " sulphur ammonium rain " problem well, will seriously restrict the development of ammonia type flue gas desulfurizing technology, especially it is applied.
Summary of the invention
