Abstract
The utility model discloses a kind of glass fibre composite filter material, comprise high molecule micropore thin layer, first surface layer, glass fibre base cloth layer and the second veil layer, described first surface layer and the second veil layer are fitted with the upper and lower surface laminated of glass fibre base cloth layer respectively, between described microporous film layers and first surface layer, be provided with high temperature resistant processing layer, described first surface layer and the second veil layer are fiberglass layer and the laminated moulding of chemical fiber layer.Its advantage is: the high and long service life of filter efficiency.
Description
Technical field
The utility model relates to a kind of filtering material, is specifically a kind of glass fibre composite filter material.
Background technology
Not only temperature is high for the flue dust that steel and iron industry, metallurgical industry and cement industry produce, concentration is large, and composition is very complicated, severe contamination air ambient.Along with rapid economic development and people's environmental consciousness constantly strengthen, country, to environmental issue pay attention to day by day, in flue dust heavily contaminated field, has formulated strict discharge standard especially.
Glass fibre is a kind of Inorganic Non-metallic Materials of excellent performance, of a great variety, has good insulating, heat resistance is strong, corrosion resistance good, and the high lamp advantage of mechanical strength, is widely used in high-temperature-resistant filtering material field.Especially aspect the off-gas recovery of the industry high-temperature fields such as cement, metallurgy, carbon black and coal-burning boiler, favored very much.For adapting to collect the needs that high-temperature flue gas fine dust reclaims, glass fabric has also evolved to three-dimensional structure from two-dimensional structure, but no matter be two dimension or three-dimensional glass fiber filter material, all have that deashing property is poor, running resistance is high, especially not high to 1 micron of following fine dust rate of recovery.And the limitation such as glass fibre is fragile material after all, have very poor, not wear-resisting, the not anti-folding of spinnability, service life is short.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: the glass fibre composite filter material that the high and long service life of a kind of filter efficiency is provided.
Technical solution of the present utility model is: a kind of glass fibre composite filter material, comprise high molecule micropore thin layer, first surface layer, glass fibre base cloth layer and the second veil layer, described first surface layer and the second veil layer are fitted with the upper and lower surface laminated of glass fibre base cloth layer respectively, between described microporous film layers and first surface layer, be provided with high temperature resistant processing layer, described first surface layer and the second veil layer are fiberglass layer and the laminated moulding of chemical fiber layer.
Further, described high molecule micropore thin layer is PTFE microporous membrane layer.
Further, described high temperature resistant processing layer comprises the matrix being made into PAN base oxidized fibre, and on matrix, is coated with fireproof paint layer.
Further, described chemical fiber layer is natural polymer fibrage or artificial macromolecular compound fibrage.
Apply a kind of glass fibre composite filter material provided by the utility model, its beneficial effect is: the PTFE microporous membrane of employing, micro-pore diameter is about 0.2-3 micron, therefore in use, collection that can 100% to 1 micron of above dust, also can reach more than 99% dust-collecting efficiency to 1 micron of following fine dust.And, first surface layer and the second veil layer are fiberglass layer and the laminated moulding of chemical fiber layer, the wearability of compound veil is improved largely compared with traditional glass veil, although glass base cloth wears no resistance, but base cloth is clipped between top layer and nexine veil, what first filter bag and skeleton friction were grinding is veil, instead of base cloth, so avoided the damage to glass base cloth.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1-high molecule micropore thin layer, 2-first surface layer, 3-glass fibre base cloth layer, 4-the second veil layer, 5-is high temperature resistant processing layer, 6-fiberglass layer, 7-chemical fiber layer.
Detailed description of the invention
For more intuitively, intactly understanding the technical solution of the utility model, existing just to carry out nonrestrictive feature description in conjunction with the utility model accompanying drawing as follows:
As shown in Figure 1, a kind of glass fibre composite filter material, comprise high molecule micropore thin layer 1, first surface layer 2, glass fibre base cloth layer 3 and the second veil layer 4, first surface layer 2 and the second veil layer 4 are fitted with the upper and lower surface laminated of glass fibre base cloth layer 3 respectively, between microporous film layers and first surface layer 2, be provided with high temperature resistant processing layer 5, first surface layer 2 and the second veil layer 4 are fiberglass layer 6 and the laminated moulding of chemical fiber layer 7.
High molecule micropore thin layer 1 is PTFE microporous membrane layer, PTFE microporous membrane layer good corrosion resistance, have advantages of smooth, can not glue ash, aperture is little, can improve strainability and the filtering accuracy of filtrate.
High temperature resistant processing layer 5 comprises the matrix (not shown) being made into PAN base oxidized fibre, and on matrix, is coated with fireproof paint layer (not shown), and high temperature resistant, anti humility performance, thermal stability are good.
Chemical fiber layer 7 is natural polymer fibrage or artificial macromolecular compound fibrage, and, in first surface layer 2 and the second veil layer 4, the ratio of chemical fibre is 0.3-0.4, make up the shortcoming that glass wears no resistance, so just reach the strong point of bringing into play various fibers, played the effect of learning from other's strong points to offset one's weaknesses.
A kind of glass fibre composite filter material provided by the utility model, the PTFE microporous membrane adopting, micro-pore diameter is about 0.2-3 micron, therefore in use, collection that can 100% to 1 micron of above dust, also can reach more than 99% dust-collecting efficiency to 1 micron of following fine dust.And, first surface layer 2 and the second veil layer 4 are fiberglass layer 6 and the laminated moulding of chemical fiber layer 7, the wearability of compound veil is improved largely compared with traditional glass veil, although glass base cloth wears no resistance, but base cloth is clipped between two-layer veil, what first filter bag and skeleton friction were grinding is veil, instead of base cloth, so avoided the damage to glass base cloth.
Certainly; these are only preferred embodiment of the present utility model; non-ly therefore limit to the scope of the claims of the present utility model, all utilization the utility model descriptions and graphic content institute for it simple and easy modification and equivalent structure change, within all should being in like manner contained in scope of patent protection of the present utility model.
