Abstract

The special filter bag of blast furnace gas, comprise filter bag body and installing ring, installing ring is provided with at the sack of filter bag body, described filter bag body comprises polytetrafluoroethylpunched punched felt internal layer, fiberglass woven weaves cotton cloth middle level and polyphenylene sulfide fibre outer, there is high-wearing feature, filter effect is better, the advantages such as long service life.

Description

The special filter bag of blast furnace gas
Technical field
The present invention relates to a kind of filter bag, the special filter bag of especially a kind of blast furnace gas.
Background technology
Along with the fast development of China's economic, iron and steel, cement, coal production rank first in the world, generated energy the second in the world.These raw material, energy industry production equipment backwardness relative to technique, resource, energy consumption are large, and seriously polluted, the dust of generation, flue dust enormous amount, sack cleaner market demand also increases thereupon.The critical component of sack cleaner is filter bag, and the quality of its dust removal performance decides the quality of sack cleaner.
In blast furnace gas field, it is short to there is the life-span in conventional filter bag, cleaning dust and dirt trouble, the problems such as poor filtration effect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the special filter bag of a kind of blast furnace gas, having high-wearing feature, filter effect is better, the advantages such as long service life.
The present invention in order to solve the problems of the technologies described above taked technical scheme is: the special filter bag of blast furnace gas, comprise filter bag body and installing ring, installing ring is provided with at the sack of filter bag body, described filter bag body comprises polytetrafluoroethylpunched punched felt internal layer, fiberglass woven weaves cotton cloth middle level and polyphenylene sulfide fibre outer, three-layer filter composition three-dimensional asymmetric carpet veneer structure, the inner surface of polytetrafluoroethylpunched punched felt internal layer is provided with multiple poly-dirt groove.
Poly-dirt groove of the present invention increases at the bottom of from installing ring to bag gradually.
Poly-dirt groove of the present invention is oval.
Beneficial effect of the present invention is: filter bag is made up of three metafiltration layers, heat-resisting quantity wearability significantly improves, because the existence of polytetrafluoroethylpunched punched felt internal layer, dust removing effects is cleared up better simultaneously and is got up easily, even if internal layer is damaged, the fiberglass woven in middle level is weaved cotton cloth and polyphenylene sulfide fibre skin high efficiencyly can also realize filter effect, improves service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of invention.
Fig. 2 is the structural representation of the inner surface of polytetrafluoroethylpunched punched felt internal layer.
In figure, 1, filter bag body, 2, installing ring, 101, polytetrafluoroethylpunched punched felt internal layer, 102, fiberglass woven weaves cotton cloth middle level, 103, polyphenylene sulfide fibre is outer, 104, poly-dirt groove.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete detailed description is further done to the present invention.
As shown in the figure, the special filter bag of blast furnace gas, comprise filter bag body 1 and installing ring 2, installing ring is provided with at the sack of filter bag body 1, described filter bag body 1 comprises polytetrafluoroethylpunched punched felt internal layer 101, fiberglass woven weaves cotton cloth middle level 102 and polyphenylene sulfide fibre skin 103, three-layer filter composition three-dimensional asymmetric carpet veneer structure, the inner surface of polytetrafluoroethylpunched punched felt internal layer 101 is provided with multiple poly-dirt groove 104.
Poly-dirt groove 104 increases at the bottom of from installing ring to bag gradually, and described poly-dirt groove 104 is oval.The existence of poly-dirt groove makes the contact area of filter bag and dust increase, more dust accumulates in poly-dirt groove, because depositing of poly-dirt groove is large, even if filter bag does not carry out dust cleaning, the use of filter bag is not affected substantially, because polytetrafluoroethylene (PTFE) water resistant, and smooth surface, the effect of dedusting is not affected, filter dirt better effects if during cleaning dedusting.
The design of filtering layer three-dimensional asymmetric structure gradient makes the porosity of filtrate reach 86 ~ 93%.
Carpet veneer structure asymmetric design, has the characteristic of " surface filtration " efficient low-resistance, and prevent dust from penetrating to greatest extent, filter efficiency reaches 99.99%, guarantees stable running resistance.
The design makes filter bag increase substantially filtrating smoke dust area in unit volume, reduces resistance, reduces sack cleaner volume, realizes the object that high-effective dust-removing is energy-conservation.The sock filtration area of same volume increases by 2 ~ 5 times, disposal ability raising 2 ~ 5 times; Volume reduction 70 ~ 90% under same filter area, weight saving 60 ~ 70%, production cost reduce by 50 ~ 60%.
