Abstract
The utility model discloses a kind of composite filter material, comprise the PTFE microporous membrane layer, PTFE impregnation process layer, superfine fibre layer, fiberglass layer, base cloth layer and the adsorption layer that set gradually, close with PTFE microporous membrane layer and superfine fibre laminating respectively on the upper and lower surface of described PTFE impregnation process layer, the upper surface of described fiberglass layer and adsorption layer and base cloth layer and lower surface lamination.Its advantage is: adopt PTFE microporous membrane layer as meeting knoisphere, there is high tensile strength and corrosion resistance, strainability is good, running resistance is low, production cost is low, long service life, is applicable to that working temperature is high, corrosivity is strong, dust content is large, the filtrating smoke dust of the high complex working condition of filtering accuracy requirement.
Description
Technical field
The utility model relates to a kind of filtering material, is specifically a kind of composite filter material of good filtration effect.
Background technology
Pollutant in some circumstance complications (high temperature, high humidity, high corrosion etc.) operating mode discharge mainly contains flue dust, SO2, SO3 (causing the chief component of low temperature acid corrosion), NOX, HF, CO2, N2, H2O etc.Be characterized in that flue gas corrosion is large, water capacity is large, fine dust is many, and the mist of oil containing in partial fume, the stickums such as trickle floccule are easily attached to and on filtrate, cause filter clogging.Therefore, people have higher requirement to the selection of filtrate.And, thick weather is more and more serious in recent years, weather scientist and medical expert think, the thick weather being caused by fine particle wants large to the hazard ratio sandstorm of health, single filtering material presents many deficiencies aspect filtration, and the filter medium that hole is large is inoperative to fine particle, although the little filter medium of hole can filter the particle that particle diameter is less, but a large amount of particles covers material surface causes material gas permeability poor, has shortened its service life.
At present, existing filtering material is all first to carry out water-proofing treatment, carry out again film Combined Processing, thin layer is just compounded in the outside of watertight composition like this, film and base material laminating are not firm, and meanwhile, airborne steam also can be attached to the surface of film, make this filtering material permeability bad, thereby also have influence on osmotic resistance.And under the high temperature and high corrosion working condition of the operating modes such as waste incineration, cement, power plant, iron and steel, chemical industry, common filtering material can not meet the requirement of special operation condition filtrating smoke dust.Have many producers to use polyphenylene sulfide fibre, aramid fiber, P84 fiber etc. to make filtering material, but the cost of these fibers is higher; Simultaneously also in various degree there is the shortcomings such as antioxygenic property is poor, anti-hydrolytic performance is poor, chemical-resistance is poor, tensile strength is low.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: the composite filter material that a kind of good combination property and low cost of manufacture are provided.
Technical solution of the present utility model is: a kind of composite filter material, comprise the PTFE microporous membrane layer, PTFE impregnation process layer, superfine fibre layer, fiberglass layer, base cloth layer and the adsorption layer that set gradually, close with PTFE microporous membrane layer and superfine fibre laminating respectively on the upper and lower surface of described PTFE impregnation process layer, the upper surface of described fiberglass layer and adsorption layer and base cloth layer and lower surface lamination.
Further, the hole of described fiberglass layer is greater than the hole of superfine fibre layer, and the hole of described superfine fibre layer is greater than the hole of PTFE impregnation process layer.
Further, in described adsorption layer, be filled with activated carbon granule.
Further, described base cloth layer is nonwoven layer.
Apply a kind of composite filter material provided by the utility model, its beneficial effect is: adopt PTFE microporous membrane layer as meeting knoisphere, there is high tensile strength and corrosion resistance, strainability is good, running resistance is low, production cost is low, long service life, is applicable to that working temperature is high, corrosivity is strong, dust content is large, the filtrating smoke dust of the high complex working condition of filtering accuracy requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1-PTFE microporous membrane layer, 2-PTFE impregnation process layer, 3-superfine fibre layer, 4-fiberglass layer, 5-base cloth layer, 6-adsorption layer.
The specific embodiment
For more intuitively, intactly understanding the technical solution of the utility model, existing just in conjunction with the utility model accompanying drawing, to carry out nonrestrictive feature description as follows:
As shown in Figure 1, a kind of composite filter material, comprise the PTFE microporous membrane layer 1, PTFE impregnation process layer 2, superfine fibre layer 3, fiberglass layer 4, base cloth layer 5 and the adsorption layer 6 that set gradually, fit with PTFE microporous membrane layer 1 and superfine fibre layer 3 respectively in the upper and lower surface of PTFE impregnation process layer 2, upper surface and the lower surface lamination of fiberglass layer 4 and adsorption layer 6 and base cloth layer 5.
In adsorption layer 6, be filled with activated carbon granule, activated carbon granule has efficient feature to the removal of organic pollution.
Described base cloth layer 5 is nonwoven layer, and nonwoven does not have graticule, cuts out and sews all very conveniently, and light weight is easily shaped.Certainly, base cloth layer 5 is for nonwoven layer is just as a kind of preferred, and base cloth layer 5 can also be used the glass fiber sewing thread base cloth layer 5 of PTFE impregnation process.
The knoisphere of meeting of the present utility model is PTFE microporous membrane layer 1, PTFE microporous membrane layer 1 good corrosion resistance, have advantages of smooth, can not glue ash, aperture is little, can improve strainability and the filtering accuracy of filtrate; The second layer is PTFE impregnation process layer 2, promotes the overall performance of filtrate, guarantees the overlay film fastness of PTFE microporous membrane layer 1; The 3rd layer is PTFE superfine fibre layer 3, and the hole of superfine fibre layer 3 is greater than the hole of PTFE impregnation process layer 2; The 4th layer is fiberglass layer 4, and the hole of fiberglass layer 4 is greater than the hole of superfine fibre layer 3, and the integral body that can increase composite filtering material is powerful, and the air-flow that is conducive to enter filtrate passes through, and reduces resistance; Layer 5 is base cloth layer 5, is the main body framework of composite filtering material, has the features such as the water of refusing, ventilative, pliable and tough, not combustion-supporting, nontoxic nonirritant, rich color; Layer 6 is adsorption layer 6, the filtering accuracy of the composite filter material of further having deducted a percentage.
A kind of composite filter material provided by the utility model, adopt PTFE microporous membrane layer 1 as meeting knoisphere, there is high tensile strength and corrosion resistance, strainability is good, running resistance is low, production cost is low, long service life, being applicable to that working temperature is high, corrosivity is strong, dust content is large, the filtrating smoke dust of the high complex working condition of filtering accuracy requirement, is the novel filter material that a kind of cost performance is very high.
Certainly; these are only preferred embodiment of the present utility model; non-so 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.
