Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of the utility model protection.
As Fig. 1-Fig. 2, the spraying layer that desulfurizing tower 5 comprises the entrance 4 being located at sidewall, the entrance offside just right with described entrance 4 and is located at above described entrance 4.The present embodiment finds according to Fluent software simulation and PILOT PLANT TRIAL measurement data, after air-flow enters desulfurizing tower 5, most air-flow is serious along the adherent flowing of desulfurizing tower 5 entrance offside, peak flow rate (PFR) is more than 10m/s, form serious washing away, and entrance 4 sidewind amount is considerably less, and form a large eddy current, smoke distribution is seriously uneven.The gas residence time of entrance offside is short, and the gas-liquid contact reaction time is short, reacts insufficient; Entrance offside exhaust gas volumn is large, and spraying cooling is limited, and local temperature is too high, and tower body is anticorrosion easily damaged.
For above-mentioned situation, the utility model embodiment provides a kind of guiding device for desulfurizing tower 5 flow fieldoptimization, described guiding device is located between described entrance 4 and described spraying layer, described guiding device comprises the first perforated panel 1, second perforated panel 3 and polylith deflector 2, described first perforated panel 1 is located at entrance 4 side, described second perforated panel 3 is located at entrance offside side, and described polylith deflector 2 is located between described first perforated panel 1 and described second perforated panel 3.Each described deflector 2 is vertically obliquely installed, and incline direction is for tilt obliquely from entrance 4 side entrance offside direction, and being obliquely installed of deflector 2 makes part high velocity air guiding entrance 4 side of entrance offside.Wherein, the first perforated panel 1 percent opening is 100%, and namely entrance 4 side is open flow-guiding structure, reduces gas-flow resistance, is convenient to air-flow is directed to entrance 4 side; The area of the first perforated panel 1 can adjust according to the diameter of different desulfurizing tower 5.
Wherein, the width of each deflector 2 and angle of inclination are different and different according to its distance from entrance 4, and angle of inclination can adjust accordingly according to desulfurizing tower 5 air inlet flow direction.Particularly, from entrance 4 side entrance offside direction, each described deflector 2 increases successively with the angle of vertical direction, and the width of each described deflector 2 increases successively, and width described here is deflector 2 width in the horizontal direction.Distance entrance 4 side is far away, and the angle of deflector 2 and vertical direction increases and is conducive to air-flow being directed to entrance 4 side; Because distance entrance offside is nearer, throughput is larger, and stream pressure is also larger, and correspondingly, the width increasing deflector 2 is conducive to the stability of deflector 2 work.In the present embodiment, described deflector 2 is set to 5 pieces; From entrance 4 side entrance offside direction, these 5 pieces of deflectors 2 are followed successively by 10 °, 10 °, 15 °, 20 °, 30 ° with the angle of vertical direction.
As Fig. 1-Fig. 2, described second perforated panel 3 is porous plate 3, but its different and different according to from entrance 4 distance of the percent opening of porous plate 3 and open pore size.Particularly, from entrance 4 side entrance offside direction, the percent opening of described porous plate 3 increases successively, and open pore size reduces successively.In the present embodiment, from entrance 4 side entrance offside direction, described porous plate 3 offers the pod apertures in three kinds of apertures successively, and these three kinds of apertures are respectively 500mm, 400mm and 300mm.When desulfurizing tower 5 diameter is less, the open pore size of porous plate 3 can suitably reduce, and can be 200mm as minimum; But should not reduce, when reducing, air-flow will significantly be increased by the resistance of guiding device again again.In addition, porous plate 3 and adjacent deflector 2 can partially overlap, namely this deflector 2 bottom is positioned at below porous plate 3, when air motion between this deflector 2 and porous plate 3 time, fraction is directed to entrance 4 side by this deflector 2, and fraction is directed to above porous plate 3 by the pod apertures of porous plate 3.The resistance adding air-flow that porous plate 3 is suitable is set, can prevents mass air flow from washing away desulfurizing tower 5 at entrance 4 offside, thus increase service life of equipment, reduce maintenance cost.
In addition, as a kind of preferred structure of the present embodiment, this guiding device is structure as a whole, and namely the first perforated panel 1, second perforated panel 3 and each deflector 2 are located on one piece of plate body.This plate body is circular, suitable with desulfurizing tower 5 diameter, and this plate body is arranged near entrance 4 side full open aperture, is porous plate 3 near entrance opposite side portion; Mid portion is processed into deflector 2 shape, hollow out process between each deflector 2, to form the circulation passage of air-flow.Be set to integrative-structure to be convenient to integral installation, to take out and change.
The utility model embodiment has following beneficial effect: by arranging the first perforated panel 1, second perforated panel 3 and polylith deflector 2, targetedly the air-flow in each region is led, make air flow method in desulfurizing tower 5 more even, thus improve the desulfuration efficiency of desulfurizing tower 5 and the stability of work, reduce environmental pollution; Tower internal drop increases little, reduces operating cost.Owing to arranging porous plate 3 at entrance offside, improve the situation of air-flow along the adherent flowing of desulfurizing tower 5 entrance offside, thus can protect the anticorrosive coat in tower, improve desulfurizing tower 5 reliability of operation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
