Aerofoil, air distribution plate and tower body and uptake flue are tightly connected, and the air distribution plate is equipped with wind distributing hole, and uptake flue is connected to demisting upper storehouse
With the lower storehouse of bubbling.
The air compartment is located at the top in storehouse in spray, and air compartment periphery inlet porting flue, and gas approach and air compartment phase
Logical, the middle position in storehouse in spray is arranged in the uptake flue.
Storehouse includes that scattering tube, bubble generator, oxidation pipeline and slurry pool, the bubble generator are located under the bubbling
The bottom of scattering tube.
The invention also includes overhead gage and lower baffle plate, overhead gage is set between storehouse and demisting upper storehouse in the spray, it is described
Lower baffle plate is set between storehouse and the lower storehouse of bubbling in spray.
The upper and lower baffle is connect with tower body sealing, and has the aperture being connected to uptake flue and scattering tube.
If the center of gas approach is h at a distance from lower baffle plate, then the position apart from lower baffle plate 2/3h is arranged in air distribution plate,
Guarantee that the desulfuration efficiency of whole device reaches 99%~99.5%.
Wind distributing hole size on air distribution plate of the present invention is identical and is uniformly distributed.
Beneficial effects of the present invention:
The present invention sprays scattering tower apparatus and uses air distributor structure, compared with the spray of existing single entry flue scatters tower,
Flue gas by air distribution plate pressure effect is uniformly distributed in spray chamber, the relative increase contact surface and cigarette of flue gas and slurry droplet
The residence time in gas storehouse in spray, to improve the preliminary desulfuration efficiency of flue gas.In addition, flue gas uses air distributor structure also
Flue gas can be weakened to the souring of tower body and uptake flue tube wall.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of air distribution plate of the present invention.
Specific embodiment
Below with reference to examples and drawings, the present invention is described in further detail, but embodiments of the present invention are not
It is limited to this.
Embodiment
As shown in Figure 1, a kind of spray of air distributor structure scatters storehouse 22 in tower, including demisting upper storehouse 18, spray and is bubbled
Lower storehouse 14 and circulator 9 according to tower body are successively demisting upper storehouse 18 from top to bottom, storehouse 22 and are bubbled lower storehouse 14 in spray.
Demister 2 and exhaust pass 1 are set in demisting upper storehouse 18, and exhaust pass 1 is arranged above demister.
Air compartment 19, spray chamber 13 and uptake flue 7 are set in storehouse 22 in spray, air compartment 19 is located at 22 top of storehouse in spray,
And the peripheral inlet porting flue 6 of air compartment 19, air compartment 19 is communicated with gas approach 6, and cloth is arranged between air compartment 19 and spray chamber 13
Aerofoil 10, air distribution plate 10 and tower body 3 are tightly connected, and wind distributing hole 23 is arranged in air distribution plate 10.Spray chamber 13 includes nozzle 5 and spray tube
4.1 uptake flue 7, connection demisting upper storehouse 18 and the lower storehouse 14 of bubbling is arranged in the present embodiment 22 center of storehouse in spray.
It is bubbled in lower storehouse 14 and scattering tube 8, bubble generator 12, oxidation pipeline 11 and slurry pool 15 is set.Slurry pool 15 is set
Set 1 slurry pool entrance 20 and 1 slurry pool outlet 21.In the spray under storehouse 22 and demisting upper storehouse 18 and bubbling storehouse 14 it
Between be respectively set overhead gage 17 and lower baffle plate 16, described two baffles and tower body 3 are tightly connected and open up and uptake flue 7 and scattered
Pipe 8 is penetrated to be open accordingly.Lower baffle 17 and 4 piece scattering tube 8 is tightly connected, and 4 scattering tubes 8 are arranged symmetrically.
The circulator 9 is used to connect spray tube 8 and slurry pool 15.
The height that air distribution plate 10 is arranged is determined by the ratio of height to diameter of exhaust gas volumn and spray scattering tower, and the air distribution plate 10 is opened
