Abstract
The utility model discloses a denitrification device with filter screens. The denitrification device comprises a flue, wherein two groups of catalysts are arranged inside the flue; the denitrification device also comprises two filter screens; the two filter screens are respectively fixed on the inner lateral wall of the flue and respectively arranged above the two groups of catalysts; the longitudinal section of each filter screen forms a V shape; the included angle of the V-shaped longitudinal section of each filter screen is 100-200 degrees. By adopting the denitrification device with the filter screens, the service life of each catalyst can be effectively prolonged, and furnace shutdown possibility caused by soot formation is reduced.
Description
Technical field
The utility model relates to a kind of denitrification apparatus, particularly relates to a kind of denitrification apparatus with filter screen.
Background technology
At present, denitrification apparatus has generally comprised flue, is generally provided with two groups of catalyst in flue, and during denitration, the flue gas of boiler can directly enter flue and enter the catalyst in SCR.There is certain defect in this mode:
Flue gas directly enters catalyst; make the bulky grain lime-ash or the ash group blocking catalyst that in flue gas, contain; cause the decline of SCR denitration efficiency; after stopping up, can aggravate the wearing and tearing of catalyst simultaneously; shorten the life-span of catalyst; if there is a large amount of dust stratifications to be deposited on catalyst, can cause blowing out, to production, make troubles.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of denitrification apparatus with filter screen, effectively the service life of extending catalyst, reduces the blowing out causing due to dust stratification.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A denitrification apparatus with filter screen, comprises flue, is provided with two groups of catalyst in flue,
Described denitrification apparatus also comprises two filter screens, and described two filter screens are individually fixed in the madial wall of flue and lay respectively at the top of two groups of catalyst,
The longitudinal section of described each filter screen is in the shape of the letter V, and the angle of the angle of the V font longitudinal section of described each filter screen is 100 ~ 200 degree.
Further, each filter screen described in the utility model is made by 304 steel.
Preferably, the aperture of the filter opening of each filter screen described in the utility model is 4mm.
Therefore compared with prior art, the utility model has following beneficial effect:
Bulky grain lime-ash during denitration in flue gas or grey group can rest on filter screen, can not enter catalyst, have effectively extended the service life of catalyst, have also reduced the blowing out causing due to dust stratification; During cleaning, personnel only need regularly filter screen to be cleared up, without blowing out cleaning, and the filter screen of the V font design bottom that can make bulky grain lime-ash in flue gas or ash group be piled up in filter screen, cleaning is got up more convenient.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
Be illustrated in figure 1 the embodiment of a kind of denitrification apparatus with filter screen described in the utility model, comprise flue 1, in flue 1, be provided with two groups of catalyst 2, the present embodiment also comprises two filter screens 3, two filter screens 3 are individually fixed in the madial wall of flue 1 and lay respectively at the top of two groups of catalyst 2, the longitudinal section of each filter screen 3 is in the shape of the letter V, and the angle of the angle α of the V font longitudinal section of each filter screen 3 is 100 ~ 200 degree.
Further, in the present embodiment, each filter screen 3 is made by 304 steel, and the decay resistance of 304 steel and resistance to elevated temperatures are all better, is therefore well suited for being applied to the working environment of denitration.
Preferably, in the present embodiment, the aperture of the filter opening of each filter screen 3 is 4mm, can filter out to greatest extent bulky grain lime-ash or ash group in flue gas.
The technical scheme above the utility model embodiment being provided is described in detail, applied specific case herein the principle of the utility model embodiment and embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
Claims (3)
