3(promptly causing the main composition of low temperature acid corrosion), NO
x, HF, CO
2, N
2, H
2O etc.Be characterized in that flue gas corrosion property is big, water capacity is big, dust specific resistance is big, fine dust is many, and the mist of oil that contains in the partial fume, stickums such as trickle floccule are prone to attached to causing filtrate to stop up on the filtrate.Therefore, the selection of filtrate is had higher requirement.
At present, under the high temperature and high corrosion working condition of operating modes such as waste incineration, cement, power plant, iron and steel, chemical industry, common filtering material can not satisfy the requirement of special operation condition filtrating smoke dust.There are many producers to use polyphenylene sulfide fibre, aramid fiber, P84 fiber etc. to make filtering materials, also have the dust removal by filtration cloth bag of part producer directly to adopt the PTFE material, but the common ground of these fibers are that cost is than higher; Simultaneously also in various degree have shortcomings such as antioxygenic property is poor, anti-hydrolytic performance is poor, chemical-resistance is poor, tensile strength is low.
The utility model content
The purpose of the utility model provides a kind of good combination property, lower-cost oxytalan composite filtering material.
Realize the oxytalan composite filtering material of the utility model purpose, comprise PTFE microporous membrane layer, PTFE impregnation process layer, the ultra-fine surface layer of oxytalan, fiberglass layer, sewing thread base cloth layer, fiberglass layer and PTFE impregnation process layer successively from dust-collecting face.
The glass sewing thread base cloth layer that said sewing thread base cloth layer is the PTFE impregnation process.
The oxytalan composite filtering material of the utility model; Have high tensile strength and corrosion resistance; Strainability is good, running resistance is low, production cost is low, long service life; Be applicable to that working temperature is high, corrosivity is strong, dust content is big, the filtrating smoke dust of the high complex working condition of filtering accuracy requirement, is the very high novel filter material of a kind of cost performance.
Description of drawings
Fig. 1 is the structural representation of the utility model oxytalan composite filtering material.
The specific embodiment
As shown in Figure 1; The oxytalan composite filtering material of the utility model comprises glass sewing thread base cloth layer 5, fiberglass layer 4 and the PTFE impregnation process layer 2 that the ultra-fine surface layer of PTFE microporous membrane layer 1, PTFE impregnation process layer 2, oxytalan 3, fiberglass layer 4, PTFE handle successively from dust-collecting face.
The composite filter material top layer (dust-collecting face) of the utility model is a PTFE microporous membrane layer 1, and PTFE microporous membrane layer 1 good corrosion resistance is smooth, can not glue ash, and the aperture is little, can improve the strainability and the filtering accuracy of filtrate; The second layer is a 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 the ultra-fine surface layer 3 of oxytalan, and the hole of formation is greater than the impregnation process layer; The 4th layer is high-quality fiberglass layer 4 with layer 6, can increase the whole powerful of composite filtering material, and porosity is greater than the ultra-fine surface layer 3 of oxytalan, and the air communication mistake that helps getting into filtrate reduces resistance; Layer 5 is a high-performance sewing thread base cloth layer 5, is the main body framework of composite filtering material.
The manufacturing approach of the oxytalan composite filtering material of the utility model is following:
1, superfine glass fibre yarn separate and close through moving back, operation such as twisting, process the sewing of 208tex glass; Operations such as the impregnation process of sewing thread process PTFE emulsion, oven dry, sintering are processed high strength heatproof sewing thread.
2, above-mentioned sewing thread is carried out warping, adopts rapier loom, plain weave technology is woven into 280g/m
2Handle the sewing thread base cloth; Adopt an advanced warping technology during warping, guarantee the uniform tension in order of yarn.
3,, form fiberglass layer with above-mentioned sewing thread base cloth two-side needled glass fibre.
4, the surperficial acupuncture of the dust-collecting face that the sewing thread after the above-mentioned acupuncture is basic or water thorn oxytalan is processed 600g/m
2Oxytalan+glass fiber composite filter material.
5, above-mentioned composite filtering material is handled through polytetrafluoroethylene (PTFE) treatment fluid mass-impregnation.The Main Ingredients and Appearance and the proportioning of described polytetrafluoroethylene (PTFE) treatment fluid are following:
6, with the surperficial hot rolling ptfe composite microporous membrane of the dust-collecting face of composite filtering material after the above-mentioned impregnation process, it with the high strength of homogenous material, low expansion and contraction, hydrolysis, high-low temperature resistant, smooth surface, ventilative hydrophobic, advantages such as corrosion-resistant together.
The beneficial effect of the oxytalan composite filtering material of the utility model is following:
1, the oxytalan composite filtering material of the utility model has excellent flexibility and decay resistance, have simultaneously strainability good, be easy to that deashing, running resistance are low, the advantage of long service life.
2, the oxytalan composite filtering material of the utility model is applicable to high temperature, dust content is big, dust size is little, deashing often, the flue dust gas filtration of the complex working condition that Korrosionsmedium is more.
3, the oxytalan composite filtering material of the utility model adopts the sewing thread of PTFE dipping to do base cloth, has very high tensile strength and decay resistance; Process compound process filtrate after, whole impregnation process of passing through ptfe emulsion again, it is high temperature resistant, decay resistance significantly improves; And the pliability of filtrate obtains very big change, and folding number promotes more than 25%.
4, after the oxytalan composite filtering material impregnation process of the utility model through the compound one deck PTFE of hot rolling microporous membrane, membrane pore size is small, porosity is high; Dust-absorbing rate reaches 99.999%; System's running resistance has only 30%～35% of traditional filtrate, because the very smooth and hydrophobic in microporous teflon membran surface has reduced the gathering of dust; Thereby the deashing amount reduces, and prolonged the service life of filter bag; The surface is waterproof, and outside the film that can water be refused, the water smoke that has but allowed to gasify freely passes through.
Through experiment, the performance comparison of the oxytalan composite filtering material of the utility model and existing glass felt, PTFE filter material, PPS filter material and P84 filter material is following:
Through above-mentioned experimental data contrast proof, the oxytalan composite filtering material intensity of the utility model is the highest; Percentage elongation is minimum, is below 1/2 of other material; Heat resistance is good; Acidproof, alkaline-resisting, anti-hydrolytic performance is best; The oxytalan composite filtering material of the utility model is owing to adopt glass as skeleton simultaneously; Greatly reduce cost, so the price of the utility model is the very high high-performance composite filter material of a kind of cost performance well below the price of above-mentioned existing filter material.
