Abstract
The filter bag for filtering smoke dust in the utility model relates to a filter bag used in the field of dust removal for high-temperature smoke, the filter bag is especially suitable for purifying smoke dust in a smoke and powder dust industrial equipment factory. The filter bag is provided with a bag body and a , wherein the bag body is formed by the warping of composite fiber cloths, the composite fiber cloths comprises a fine fiber layer, a base cloth layer and a crude fiber layer, the fine fiber layer and the crude fiber layer are respectively compacted on the two sides of the base cloth layer, the fine fiber layer is located at the internal of the bag body, the crude fiber layer is located at the external of the bag body, the fine fiber layer is provided with a fine fiber net, the crude fiber layer is provided with a crude fiber net, the fine fiber net and the crude fiber net are both 12 layers. the mass per unit area of the fine fiber net and the crude fiber net is 22 g/m2. The fine fiber net and the crude fiber net are made from spunlace felt BFS materials or aramid fiber composite materials. The filter bag for filtering smoke dust in the utility model is advantaged by reasonable design, improvement of filtering efficiency of filter bag as well as service life.
Description
Technical field
What the utility model filtrating smoke dust filter bag related to is the filter bag that use in a kind of high temperature fume dust removal field, is specially adapted to exhaust gas dust industrial equipment factory and purifies the filter bag that flue dust uses.
Background technology
At present external bag-type dusting is the extensive use smoke filtration, the external special-purpose filter bag of making according to industry-by-industry smoke filtration operating mode characteristics, as high temperature resistant type, acid corrosion-resistant type, alkali corrosion resistance type, waste incineration tailored version etc., replaced high-pressure electrostatic precipitation and other dedusting technologies, bag-type dusting has become the requisite technical equipment of developed country's control smoke pollution.And domesticly also do not have this type of filter bag product, and high-end filter bag product still occupies the staple market share by offshore company, and especially in the high temperature fume dust removal field, the novel filter bag that quickens research and development China independent intellectual property right seems particularly urgent and important.
The trickle particle bisque of present existing filter bag design penetrates filter bag easily, can not control dust removing effects, causes air pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of filtrating smoke dust filter bag at above-mentioned weak point, the filtrating smoke dust filter bag takes following scheme to realize: the filtrating smoke dust filter bag has bag and sack, bag is formed by the complex fabric cloth parcel, complex fabric cloth comprises fine fiber layer, base cloth layer and crude fibre layer, fine fiber layer and crude fibre layer are compressed on the base cloth layer both sides respectively, described fine fiber layer is positioned at the bag inboard, the crude fibre layer is positioned at the bag outside, fine fiber layer has 12 layers of fine fiber webs, and fiber is thinner, is dust-collecting face, can control the infiltration of particle bisque, the crude fibre layer has 12 layers of crude fibre net, and fiber is thicker, can guarantee the tension intensity of filter bag.
The mass area ratio of described fine fiber webs and crude fibre net is 22g/m2.Fine fiber webs and crude fibre net adopt water thorn felt glass this material of fluorine or aramid fiber composite material to make.
The utility model filtrating smoke dust filter bag is reasonable in design, fine fiber webs and crude fibre net all adopt water jet process to make and himself tangle to form the filtration surface layer with splendid filter efficiency, again through PTFE (polytetrafluoroethylene (PTFE)) emulsion impregnation process, surfacing is closely knit smooth, therefore in the dedusting of blowback wind, use and to significantly improve ash-removal effect, long-time running reduces filtration resistance and saves energy consumption, and prolongs its service life.When reducing filtrate high-performance fiber raw material, improve also that filtering material is wear-resisting, folding, corrosion-resistant, optimize the filter bag structure, the filter efficiency and the service life of having improved filter bag.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing:
Fig. 1 is the structural representation of the utility model filtrating smoke dust filter bag.
Fig. 2 is the bag cross sectional view of the utility model filtrating smoke dust filter bag.
Among the figure: 1, bag, 2, sack, 3, fine fiber layer, 4, the crude fibre layer, 5, base cloth layer.
The specific embodiment
With reference to accompanying drawing 1～2, the utility model filtrating smoke dust filter bag has bag 1 and sack 2, bag 1 is formed by the complex fabric cloth parcel, complex fabric cloth comprises fine fiber layer 3, base cloth layer 5 and crude fibre layer 4, fine fiber layer 3 and crude fibre layer 4 are compressed on base cloth layer 5 both sides respectively, described fine fiber layer 3 is positioned at bag 1 inboard, crude fibre layer 4 is positioned at bag 1 outside, fine fiber layer 3 has 12 layers of fine fiber webs 6, and fiber is thinner, is dust-collecting face, can control the infiltration of particle bisque, crude fibre layer 4 has 12 layers of crude fibre net 7, and fiber is thicker, can guarantee the tension intensity of filter bag.
Embodiment 1: fine fiber webs 6 and crude fibre net 7 employing water jet processes make himself to tangle and form the filtration surface layer with splendid filter efficiency, again through PTFE (polytetrafluoroethylene (PTFE)) emulsion impregnation process, surfacing is closely knit smooth, therefore in the dedusting of blowback wind, use and to significantly improve ash-removal effect, long-time running reduces filtration resistance and saves energy consumption, and prolongs its service life.
Embodiment 2: fine fiber webs 6 and crude fibre net 7 adopts aramid fibers and base cloth is compound and carding, when reducing filtrate high-performance fiber raw material, improve also that filtering material is wear-resisting, folding, corrosion-resistant, optimize filter bag structure, the filter efficiency and the service life of having improved filter bag.
