Embodiment Construction
[0018] Such as figure 1 As shown, the new wet flue gas desulfurization and dust removal method of the present invention, it is to introduce the flue gas into the lower part of the absorption tower, make it cool by the evaporation of water, the lower absorption area is strongly mixed with the washing liquid in a countercurrent manner, and then the flue gas passes through the reaction Droplet separator at the top of the column, draining from the side.
[0019] The present invention includes absorption tower absorption zone, oxidation zone and neutralization zone.
[0020] The washing liquid of the present invention is pumped out from the stock tank and sent to the nozzles of each layer arranged up and down in the reaction tower, and is evenly distributed in the reaction tower in the form of very fine particles through the hole cone nozzles in each layer. SO in flue gas 2 Washed and neutralized, the calcium sulfite formed is oxidized to gypsum by injecting air into the upper pa...
