The present invention adopts the mode of both surface filtration, meets knoisphere aperture minimum, by dust-filtering outside cloth, filtering material can not be caused to block, and the dust being deposited on top layer is easy to remove, good filtration effect; Filtering material strength and toughness is good, long service life; Long filament and filtering material are easy to produce, cost-saving.
Description
Technical field
The present invention relates to a kind of environmental protection dust removal and filtration material, especially a kind of Spunbond filament filter material. .
Background technology
In the production of needle punched non-woven fabrics, there are dry method (staple fibre), spunbond (long filament) two big class production technology. Wherein, the history of chopped fiber needle-punched technology relatively early, is most widely used, but due to the technical process of short fine nonwoven production comparatively complicated, short fibre is produced and nonwoven production often is gone to undertake by different enterprise, causes product to make and makes this increase. Number of devices is many, and the link of required control is also many, it is thus desirable to labor force is more. Owing to the travelling speed of equipment is low, therefore production efficiency is low, powerful low, the poor air permeability of product, powerful increase by one layer of woven cloth if increasing in the middle of acupuncture cloth production cost can be caused again to increase.
Spun-bond process, as nonwoven production technology with the fastest developing speed at present, more and more occupies important status. It utilizes chemical fibre spinning principle, makes the laid one-tenth net of continuous filament fibers in polymkeric substance spinning process, and fibre web is reinforced through machinery, chemistry or thermal means and become non-woven.
Existing environmental protection dust removal installation filter cloth be exactly mainly chopped fiber needle-punched non-woven fabrics, the raw material of employing is staple fibre, employing be carding; Due to short fibre, between fiber, only frictionally combines, and easily moves when being subject to external force, and ultimate strength is lower. Owing to the needling density of chopped fiber needle-punched non-woven fabrics is big, the space between fiber is little, and therefore its ventilation property is poor. Staple fiber nonwoven fabric filtering material is generally suppressed by 7-8 layer filamentary material, and there is hard skeleton centre, and fibre number is big; And every layer of aperture is identical, cause dust easily long-pending staying meet knoisphere surface, after surface apertures blocks, dust cannot be removed, and efficiency of dust collection is low.
Summary of the invention
The embodiment of the present invention is solve that existing dust removal installation filtering material strength and toughness is poor, production cost height, dust easily deposit, the problem of not easy-clear, it provides one Spunbond filament filter material.
A kind of Spunbond filament filter material, described Spunbond filament filter material is the multilayered structure that fiber filament is entwined, and each Rotating fields is the netted of the laid one-tenth of filament fiber. Actual use can directly be wound around the filter bag needed for laid one-tenth dedusting, it is also possible to as the filtering layer of filter vat.
Further, the filament diameter of described Spunbond filament filter material each layer is different, meets knoisphere filament diameter minimum, and from meeting knoisphere, filament diameter progressively increases.
Further, the pore size of described Spunbond filament filter material each layer is different, meets knoisphere aperture minimum, and from meeting knoisphere, aperture progressively increases.
As preferably, the filament diameter of described Spunbond filament filter material each layer is between 10-60 micrometer range.
As preferably, the fibre number of described Spunbond filament filter material each layer is between 1-6 dawn scope.
As can be seen from the above technical solutions, the embodiment of the present invention has the following advantages:
1, adopting the mode of both surface filtration, meet knoisphere aperture minimum, by dust-filtering outside cloth, filtering material can not be caused to block, the dust being deposited on top layer is easy to remove, good filtration effect;
2, filtering material strength and toughness is good, long service life;
3, long filament and filtering material are easy to produce, cost-saving.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation;
Wherein: 1-meets knoisphere.
Embodiment
Below in conjunction with drawings and Examples, the technical scheme of the present invention is further explained:
The embodiment of the present invention is solve that existing dust removal installation filtering material strength and toughness is poor, production cost height, dust easily deposit, the problem of not easy-clear, it provides one Spunbond filament filter material.
See Fig. 1, described Spunbond filament filter material is the multilayered structure that fiber filament is entwined, and each Rotating fields is the netted of the laid one-tenth of filament fiber. The filament diameter of Spunbond filament filter material each layer is different, meets knoisphere 1 filament diameter minimum, and from meeting knoisphere 1, filament diameter progressively increases. The pore size of Spunbond filament filter material each layer is different, meets knoisphere 1 aperture minimum, and from meeting knoisphere 1, aperture progressively increases. As preferably, the filament diameter of described Spunbond filament filter material each layer is between 10-60 micrometer range. The fibre number of described Spunbond filament filter material each layer is between 1-6 dawn scope. When filament diameter and filtrate aperture are between this scope, the filter effect of filtrate is best.
Long filament can be directly wound around the filter bag shape needed for laid one-tenth dedusting by actual use, it is also possible to Spunbond filament filter material is used as the filtering layer of filter vat. With the flue gas of dust from meeting knoisphere 1 through Spunbond filament filter material, owing to meet the filament diameter of knoisphere 1 minimum, filtrate aperture is also minimum, namely dust is filtered the surface in Spunbond filament filter material meeting knoisphere 1, owing to Spunbond filament filter material filament diameter from meeting knoisphere 1 progressively increases, aperture also progressively increases, so leading to, to meet the dust diameter of filtering layer after knoisphere 1 into Spunbond filament filter material all little than the aperture of filtering layer, can not cause the obstruction of filtering layer. Filter easily to shake off at the dust meeting knoisphere 1 surface, convenient removing.
The present invention adopts the mode of both surface filtration, meets knoisphere 1 aperture minimum, by dust-filtering outside cloth, filtering material can not be caused to block, and the dust being deposited on top layer is easy to remove, good filtration effect; Filtering material strength and toughness is good, long service life; Long filament and filtering material are easy to produce, cost-saving.
Above a kind of Spunbond filament filter material provided by the present invention is described in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the present invention, all will change in specific embodiments and applications, the number of plies amount of such as Spunbond filament filter material and pore size, all can do respective change according to actual needs.In sum, this description should not be construed as limitation of the present invention.
