The specific embodiment
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment sees accompanying drawing 1,2,3,4, a kind of deduster; Comprise have air inlet 101, the deduster cylindrical shell 1 and the shower 4 of delivery port 102 and exhaust outlet 103; Pond 5 is equipped with a water pump 6 in the described pond 5, described water pump 6 is communicated with described shower 4.Through this water pump 6, come to supply water to shower 4, make shower 4 can spray the needed water of dedusting; Pond 5 also has the function of deposition; Can the water after the dedusting of coming out from delivery port 102 be precipitated, and pond 5 is arranged on the outside of deduster cylindrical shell 1; Size can be carried out according to actual, cleans also very convenient; Air inlet 101, delivery port 102 are all opened on the sidewall of deduster cylindrical shell 1 position near the bottom; So just can make that waste gas gets into from the bottom; Discharge from the exhaust outlet 103 at deduster cylindrical shell 1 top, be connected with a blower fan 4 that is used to import waste gas on the described air inlet 101, the import of blower fan 4 is connected with the outlet of boiler or kiln; Through blower fan 4 waste gas is introduced in the deduster, described deduster cylindrical shell 1 has cavity volume 104; The place that the just useless G&W of this cavity volume 104 exchanges; In the described cavity volume 104 fixed leg 2 is arranged, fixed leg 2 can be processed by stainless steel or concrete, can certainly be that other corrosion-resistant material is processed; Described fixed leg 2 in the vertical directions are fixed with multilayer baffle plate 3; Each layer baffle plate 3 is made up of a plurality of fan-shaped blades 301, the blade 301 interlaced arrangements of the baffle plate 3 of adjacent two layers, and each blade 301 is a slanted angle a with horizontal plane; Be that the side that can intersect after two prolongations of each blade 301 exists difference in height; Can find out that from accompanying drawing 4 these two sides and horizontal plane are off plumbs, and with between adjacent two blade 301 of layer gapped 302.In the present technique field, see accompanying drawing 4, can find out that from accompanying drawing the scope of said slanted angle a is: 5 °≤a≤30 ° wherein with, slanted angle a=22.5 ° is best.The size in the size of slanted angle a and gap 302 has direct relation, and angle is big, and the gap is just big, and angle is little, and the gap is just little.In addition, blade 301 can adopt stainless steel or concrete to process, and perhaps other corrosion-resistant material is processed, and sees accompanying drawing 1 and accompanying drawing 3; Can find out that from this two width of cloth figure the baffle plate 3 of this embodiment is four layers, each layer baffle plate 3 is made up of 8-24 blade 301; Blade 301 quantity how much be according to the size decision of cylindrical shell, bigger when cylindrical shell, when diameter is thicker, blade is some more; Otherwise then less, equally in order to obtain better dust removing effects, the quantity of baffle plate 3 can be multilayers such as 5,6,7,8; Certainly, also can be 3,2 or even 1 layers, just effect is not good enough comparatively speaking.And in order to increase contact area to greatest extent, prolonging useless G&W moral swap time, the axial projective area that constitutes the blade 301 of every layer of baffle plate 3 equates with the cross-sectional area of described cavity volume 104 with fixed leg 2 axial projective area sums.
