Description

Filtering material of a kind of high capture rate and uses thereof
Technical field
The present invention relates to a kind of filtering material and purposes of high capture rate.
Background technology
Along with Chinese society, the development of economy and improving constantly of living standards of the people, people will be more and more higher to the quality requirement of atmospheric environment, and the application of filtering material is also more and more extensive.Because conventional filter material also exists defect filtering the more aspect such as fine dust particles, filtering accuracy, this just requires us to develop the different filtering material of a kind of structure.As everyone knows, there is direct relation in the filter efficiency of filtering material and its aperture, and the size in aperture is relevant with the fibroreticulate fibre diameter of formation.
The fleece that all adopts the crude fibre of average diameter 20~200 μ m to form as Chinese publication CN101168112A discloses a kind of non-filtration surface layer, in the time of acupuncture, crude fibre takes to and filters in surface layer, fibre diameter chap, it is large that aperture becomes, will cause arresting efficiency to reduce, thereby thinner powder dust particle is difficult to become trapped in.
And for example to disclose a kind of surface layer that filters be that heat resistant fibre and 90wt%~10wt% average diameter below 10 μ m is that 10~20 μ m heat resistance fibers mix the fleece forming by containing 10wt%~90wt% average diameter to Chinese publication CN101406780A, adopt crude fibre because filter surface layer, filter surface layer arresting efficiency and reduce.
Summary of the invention
The object of the present invention is to provide filtering material of the high capture rate that a kind of crushing is low, wearability good, precision is filtered and uses thereof.
Technical solution of the present invention is as follows: the filtering material of the high capture rate of the present invention is to be made up of filter course, intermediate layer, non-filter course, and described filter course is fleece, and in described fleece, the polyphenylene sulfide fibre of diameter 1~10 μ m accounts for 90~100 % by weight; Described non-filter course is to be to be greater than 10 polyphenylene sulfide fibres that are less than or equal to 20 μ m to mix the fleece forming by the polyphenylene sulfide fibre of diameter 1~10 μ m with diameter, and in described non-filter course, the weight ratio of the fiber of two kinds of different-diameters is 0~100%:100~0%; Intermediate fabric enhancement layer is formed and is formed by heat resistant fibre.
Above-mentioned filter course is the fleece being made up of the polyphenylene sulfide fibre of diameter 1~10 μ m (hereinafter to be referred as fine fibre), use fine fibre at filter course, be the average pore size by reducing filter course hole, thereby reach the effect of both surface filtration, improve the arresting efficiency of filtering material to dust.If filter course fibre diameter is greater than 10 μ m, can causes filter course aperture to increase, thereby reduce the arresting efficiency of filter felt.The content that fine fibre accounts for filter course is 90~100 % by weight, if the content of fine fibre is lower than 90 % by weight, in the time that filter course, base cloth and non-filter course carry out acupuncture, non-filter course to enter filter course compared with crude fibre more, can cause like this average pore size of filter course hole to become large, reduce the arresting efficiency of filter felt.In above-mentioned filter course, may also contain other fibers below 10 % by weight, this is that while carrying out acupuncture due to filter course, base cloth and non-filter course, the part fiber of non-filter course is brought into filter course.Consider from obtaining higher dust catching efficiency, the content of above-mentioned fine fibre is 95~100 % by weight preferably.
Above-mentioned non-filter course is to be to be greater than 10 polyphenylene sulfide fibres (hereinafter to be referred as general fibre) that are less than or equal to 20 μ m to mix the fleece forming by the polyphenylene sulfide fibre of diameter 1~10 μ m with diameter, this non-filter course not only plays a supportive role, and plays the effect of dust being carried out to secondary filter.Add fine fibre can improve the arresting efficiency of filtering material, add general fibre can improve the wearability of filtering material and reduce crushing, so the fleece that non-filter course of the present invention adopts fine fibre and general fibre to be mixed to form has not only improved filtering accuracy, can trap thinner bisque particle, improve wearability simultaneously and reduced crushing.If non-filter course is the fibroplastic fleece that is greater than 20 μ m by diameter, the words that all formed by crude fibre, when acupuncture, crude fibre is brought in filter course, in filter course, contain crude fibre, it is large that the filtering material aperture making becomes, and will cause arresting efficiency to reduce, thereby be difficult to trap thinner bisque particle.Therefore the present invention mixes to come balance filtration performance and crushing by being greater than 10 polyphenylene sulfide fibres that are less than or equal to two kinds of different-diameters of 20 μ m with diameter 1~10 μ m with diameter at non-filter course.
Consider the filtering accuracy that can improve filtering material, trap thinner bisque particle, can improve again wearability simultaneously and reduce crushing, preferably 10~90%:90~10% of weight ratio of the fiber of two kinds of different-diameters in non-filter course of the present invention.
Intermediate fabric enhancement layer of the present invention refers to the sparse tissue layer of the one being formed by yarns interwoven, work to keep mechanical strength, the fiber that forms fabric enhancement layer is heat resistant fibre, and heat resistant fibre can be the poly-phthalein amine fiber of contraposition aromatics, meta-aromatic polyamide fiber, polyphenylene sulfide fibre, poly-phthalimide fiber, fluorine series fiber, carbon fiber, glass fibre etc.From the viewpoint of chemical proofing, hydrolytic resistance, preferably use polyphenylene sulfide fibre and fluorine series fiber; High from the viewpoint of mechanical strength, most preferably polyphenylene sulfide fibre.
The filtering material of high capture rate of the present invention, above-mentioned polyphenylene sulfide fibre is short fiber or long filament.Preferably use staple yarn, the fibroreticulate complexing of staple yarn and filter course, non-filter course is better, and it is many that the surface area of fiber becomes, and therefore the dust catching efficiency of filtering material is better.
According to JISL 1096 standards, the grammes per square metre of the filtering material of high capture rate of the present invention is 300~800g/m 2.Above-mentioned grammes per square metre must meet the requirement of arresting efficiency, if grammes per square metre is greater than 800g/m 2, increased cost; If grammes per square metre is less than 300g/m 2, the fleece that plays dust removal by filtration effect is too thin, cannot meet the effect of high arresting efficiency, preferably 450~700g/m of the grammes per square metre of filtering material 2.
The filtering material of high capture rate of the present invention, its porosity is 30~70%.If the porosity of filtering material is greater than 70%, the arresting efficiency of dust is reduced; If the porosity of filtering material is less than 30%, throughput is too low, has improved the pressure loss, has increased the energy consumption of dust removal machine blower fan.Porosity preferably 50~65%.
To the following particulate of PM2.5, the capture rate of filtering material of the present invention is 85~98%.PM2.5 represents that in atmosphere, diameter is less than or equal to the particle of 2.5 microns, and PM2.5 particle diameter is little, is rich in a large amount of poisonous and harmful substances, and time of staying in atmosphere is long, fed distance is far away, thereby larger on the impact of health and atmosphere quality.If capture rate is less than 85%, the harmfulness of PM2.5 particulate can not be removed so; Must be very little very little if capture rate higher than 98%, is filtered the aperture of felt so, just have very high crushing, cause circulation timei very short, it is many that pulse dust cleaning number of times becomes, and it is many that pulse gas consumption becomes, and causes unnecessary economic loss.
According to the 8.27.1 A method of JISL 1096 standards, under pressure 125Pa, the venting quality of the filtering material of high capture rate of the present invention is 5~50cc ∕ cm 2s.If the venting quality of filter felt is less than 5cc ∕ cm 2s, must cause cleaning cycle to shorten so, and it is many that pulse dust cleaning number of times becomes, and it is many that pulse gas consumption becomes, and causes unnecessary economic loss; If the venting quality of filter felt is greater than 50 cc ∕ cm 2s, the aperture ratio of explanation filter felt is larger so, is unfavorable for the filtration of dust.
According to JISL 1096 standards, the filtering material of high capture rate of the present invention through the hot strength of broadwise all more than 500N ∕ 5cm.Filtering material in use must overcome the gravity of self and the gravity of appendix dust, and the impulsive force of compressed air to filtering material when deashing.
After the preparation method of filtering material of the present invention is the fleece that stacks gradually filtering surface one side, the middle fleece that strengthens fabric and non-filtering surface one side, take needling density as 280~360 Gen ∕ cm 2carry out that acupuncture obtains.
Process by the filter course of filtering material of the present invention is singed or light processing processing, can further improve like this dust peeling property energy or dust catching efficiency.
