Preferably, described swirl-flow devices comprises annular frame, cylindrical center post and some eddy flow plates, described eddy flow plate one end is arranged on the inwall of frame, and the other end of described eddy flow plate is arranged on the newel, acutangulates or the obtuse angle between described eddy flow plate and the horizontal plane; Impel flue gas to seethe and move, and force flue gas to form knuckle and fall the slow rate of climb, make that this forms one-level with flue gas and repeatedly blends reverse doctor solution again, realizes whole positive desulfurization downwards at this along inwall.
Preferably, described cylindrical shell top also is built-in with demister, described demister comprises the demist plate of annular frame, some clamps, at least one fixed bar and some bendings, described demist plate is arranged in the annular frame, be provided with clamp between described per two blocks of demist plates, described clamp is arranged on the fixed bar, and described fixed bar wore the demist plate, and described fixed bar two ends are arranged on scuncheon; Utilize the demist plate of bending to increase the displacement of rising fog and change the fog moving direction, the fusion that fog is tried one's best herein forms water droplet, makes fog can not run out of desulfurizing tower and pollutes.
Preferably, described demist plate is spliced into by upper plate, middle plate, three blocks of straight plates of lower plate, and described upper plate and horizontal plane become bear 90 degree angles between plate and the upper plate in described in angle of 45 degrees, becomes 90 to spend angles between described middle plate and the lower plate; Increase the mobile distance of fog as far as possible, fog can be merged form the angle that is provided with that water droplet reaches better effects.
Compared with prior art; the utility model has the advantages that: collection rotational flow dust-removing, multistage dust-removal and desulfurizing are the whole body; after containing the waste gas incision import of a large amount of dusts; move upward along circular vertical cylindrical shell; meet the water that inwall flows down; rub; slough a large amount of particle dust; alleviated the operating pressure of spray system greatly; the dust of going out enters water circulation tank with flowing water, has reduced the workload of operation excavation dust, has reduced operating cost; compact conformation, reasonable in design is taking the dedusting and the desulfurization work that just can realize on tens square metres the ground middle-size and small-size kiln.Apparatus cost is low, good dedusting effect, and desulfurization performance is very desirable, efficiency of dust collection 92%, and desulfuration efficiency is more than 90%.
