Abstract
The invention provides a high-temperature-resisting bag-type dust collector bag. The high-temperature-resisting bag-type dust collector bag comprises an internal skeleton, a filter material layer covering the skeleton and a covering film covering the outer surface of the double-layer filter material layer, and the filter material layer is a blended fabric of glass fibers, polyimide fibers and ceramic fibers; the covering film is a polytetrafluoroethylene porous film. The high-temperature-resisting bag-type dust collector bag can be used for collecting the dust in a high-temperature environment.
Description
Technical field
the present invention relates to a kind of high temperature resistant bag filter cloth bag, belong to dust collection device technical field.
Background technology
Bag filter is most popular a kind of dust-precipitator in cement industry.It more than 99%, can also remove 1 μm even grit of 0.1 μm to the efficiency of dustshot (1 μm ~ 5 μm).The adaptability of bag filter is stronger, not by the impact of dust specific resistance, also there is not other pollution problem, is choosing under suitable filter aid condition, can remove solid, gas two pollutants in gas simultaneously.Due to this feature, in cement industry, all discharging airborne dust point places all use bag filter substantially.
The filter cloth surface of sack cleaner has countless interlaced fibre cover, be greater than the grit of filter cloth eyelet in gas by inertia force effect, kept off by filtration resistance and sink, gas then flows through from fiber cloth hole.Grit is trapped between filter cloth surface or gap, forms grit filter course, and the void ratio filter cloth eyelet of this layer of grit layer formation is little, so it serves the effect of the less grit of collection.Along with the thickening of this layer of grit layer, filter cloth permeability reduces, and resistance increases sharply, and purification efficiency also reduces, and now needs deashing process.Require that filter cloth materials has the aperture of 20 ~ 50 microns, and 5 ~ 10 microns, surperficial fine hair aperture.Also should have gas permeability, tension and shear resistance, sometimes also require good resistance to gentle corrosion resistance, quality is wanted evenly.Conventional filter cloth materials has the animal and plant fiber fabrics such as cotton, tussah silk, wool.Gradually adopt organic and inorganic rayon or its blending product such as nylon, Orlon, terylene, glass fibre in recent years.Existing chain cloth performance is still perfect not, can not be applicable to various working environment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of high temperature resistant bag filter cloth bag is provided.
High temperature resistant bag filter cloth bag of the present invention, comprise inner skeleton, be wrapped in the filtering material layer on skeleton and cover the overlay film of double medium filtration material layer outer surface, described filtering material layer is the blend fabric of glass fibre, polyimide fiber and ceramic fibre; Described overlay film is polytetrafluoroethylene (PTFE) microporous membrane.
The content of the glass fibre in described filtering material layer is 40-50 weight portion, and the content of polyimide fiber is 40-50 weight portion, and the content of ceramic fibre is 10-20 weight portion.
High temperature resistant bag filter cloth bag of the present invention can be used in gathering dust of hot environment.
