The distal end side of flow direction is provided with filter net cloth 42 (as shown in Figure 4), so that flue gas 100 is by the overall pocket of filtering rotating disk 4
Firmly, certainly, it will be appreciated by those skilled in the art that filter net cloth 42 can also all be set in the both sides of helicla flute 41, to increase
The response area of big sulfur dioxide and ammoniacal liquor, having the disadvantage the flow resistance of flue gas 100 can become big, and efficiency of dust collection can be reduced, energy consumption
Also it can accordingly increase, but removal effect can be better.
When dedusting is used, drive shaft 3 drives filtering rotating disk 4 to rotate, and makes the outermost side opening of helicla flute 41
411 direction is identical with the rotation direction for filtering rotating disk 4, because the outermost side opening 411 of helicla flute 41 can be immersed in ammoniacal liquor 2
Below liquid level, therefore, when the outermost side opening 411 of helicla flute 41 is immersed into ammoniacal liquor 2 and then produces ammoniacal liquor 2, one
Stock ammoniacal liquor 2 will be along the spiral of helicla flute 41 to the center flow of filtering rotating disk 4, the ammoniacal liquor (line at the center away from filtering rotating disk 4
Speed is bigger) it can be attached in helicla flute 41 under the influence of centrifugal force, but more it is proximate to filter the ammonia at the center of rotating disk 4
Water (linear velocity is smaller), its centrifugal force is smaller, thus turn to top ammoniacal liquor will from filtering rotating disk 4 center come down in torrents and
Under, with filtering rotating disk 4 rotation, ammoniacal liquor continually to filtering rotating disk 4 center flow, and from filtering rotating disk 4 in
The heart flows downward, so as to infiltrate the filter net cloth 42 of whole filtering rotating disk 4.The present invention said structure substantially increase flue gas with

5-10 centimetres below the liquid level of ammoniacal liquor 2.I.e., in the above-described embodiments, the 5 pairs of filtering rotating disks 4 of ring baffle set using both sides
Gap between housing 1 is sealed, simultaneously as the ammoniacal liquor 2 of the lower section of housing 1 itself provides water seal, therefore annular
The lower end of baffle plate 5 can be too many below liquid level without extending to, it is only necessary to which extension ends in 5-10 centimetres of the liquid level lower section of ammoniacal liquor 2 i.e.
Can, material and cost can be saved.Particularly, if ring baffle 5 is whole loop configuration, that is, the bottom of housing 1 is extended to
Ring baffle 5 be all the state stretched out from inner surface, then the loop configuration protruded from the bottom of housing 1 can influence the stream of ammoniacal liquor
Dynamic property, and solid matter can also be deposited near loop configuration and be difficult to remove, prominent structure be also unfavorable for the later stage maintenance,
Ring baffle 5 in the work, therefore the above embodiment of the present invention such as cleaning particularly preferably needs to extend and by the end of under liquid level
Square 5-10 centimetres.
In order to improve the intensity of filtering rotating disk 4, in another specific embodiment, as shown in figure 3, helicla flute 41 is at least
