Abstract
The utility model relates to a filtering material for filtering superfine dust with the granularity being less than 2 microns, and a preparation method of the filtering material. The conventional filtering material has the defects of non-uniform ventilation, easiness in demoulding, short service life and the like, so that an application effect and the cost performance of a bag type dust collector are not very ideal. The utility model provides the filtering material for filtering the superfine dust, which is characterized by being composed of three layers of structures and the three layers comprise an upper-layer superfine denier fiber layer (0.05-0.08 deniers), a middle-layer woven net cloth layer and a low-layer rough denier fiber layer (2.65 deniers); and the weight content of the superfine denier fiber layer, the woven net cloth layer and the rough denier fiber layer is (185-220): (80-110): (185-220). The filtering precision of the filtering material disclosed by the utility model is improved and the whole ventilation performance of the filtering material is improved.
Description
Technical field
The utility model relates to a kind of industrial filtrate method, relates in particular to the filtrate that a kind of ultrafine dust that can be used for below the 2 μ m filters.
Background technology
Along with rapid economic development of China, people's environmental protection consciousness strengthens day by day, also more and more pays attention to healthy.The application of sack cleaner very extensively must be adopted sack cleaner efficiently to the processing of flue gas, dust usually in commercial production.And at present the filtrate of sack cleaner selects for use the fiber at 1.5～2.2 dawn to process filter bag mostly, though can play filter effect preferably to the above dust of 10 μ m, can only utilize coated filter material to realize for the filtration of the dust below the 5 μ m.Defectives such as to have a resistance big because of coated filter material, and gas permeability is inhomogeneous, causes demoulding easily, and service life is short are so effect in sack cleaner and cost performance are not very good.
The utility model content
The utility model provides a kind of filtrate that ultrafine dust filters that is used for to the defective that prior art exists, and has the function of filtering ultrafine dust preferably, also has support strength and permeability preferably.
For this reason; The utility model is taked following technical scheme: a kind of filtrate that is used for the ultrafine dust filtration; It is characterized in that: form by three-decker; Comprise the superfine Denier fibre layer (0.05～0.08 dawn) on upper strata, the woven net layer of cloth in middle level and the coarse denier fiber layer (2.65 dawn) of lower floor, the content of described superfine Denier fibre layer, woven net layer of cloth and coarse denier fiber layer is (weight portion): 185～220: 80～110: 185～220.
The content of described superfine Denier fibre layer, woven net layer of cloth and coarse denier fiber layer is (weight portion): 200: 100: 200.
The warp-wise brute force of said woven net layer of cloth is >=and 1600N (50mm * 200mm), the broadwise brute force is >=(50mm * 200mm), the mass area ratio of said woven net layer of cloth is 80～110g/m2 to 1500N.
The above-mentioned filtrate production method that is used for the ultrafine dust filtration comprises the steps:
1. will mix, be carded to the thin dawn web layer in upper strata through shredding, homogenizing without opening fine fine count fiber;
2. coarse denier fiber is mixed, is carded to lower coarse dawn web layer through shredding, homogenizing;
3. needling process is carried out without opening the mixed layer of inserting woven screen cloth between fine thin dawn web layer and the lower coarse dawn web layer in the upper strata that makes, make the semi-finished product filtrate;
4. the semi-finished product filtrate that makes is carried out chemistry and open fine the processing; Make the upper strata of filtrate become the superfine Denier fibre layer at 0.05～0.08 dawn; The woven net layer of cloth in middle level and lower coarse dawn fibrage remain unchanged, and promptly making the upper strata is that superfine Denier fibre layer, middle level are that woven screen cloth, lower floor are the filtrate semi-finished product of coarse denier fiber layer;
5. above-mentioned filtrate semi-finished product are carried out tentering thermal finalization, singe, make final filtrate after the processing such as press polish.
The chemistry of described step in 4. open fine handle to be generally subtract alkali number and handle.When handling through subtracting alkali number, surface layer can produce very big variation, and a fiber originally produces 37 fibers through subtracting the alkali treatment meeting, so the diameter of fiber is just little, has reached ultra-fine degree.
Described to subtract time that alkali number handles be that 30～40min, temperature are that 85～100 ℃, bake out temperature are 160～180 ℃, and drying time is 8～10min.
The utlity model has following beneficial effect:
1, the superfine Denier fibre layer is adopted on the upper strata of filtrate, and has uniform gas permeability, can realize secondary filter to the ultrafine dust below the 2 μ m, has improved the filtering accuracy of filtrate.
2, the centre of filtrate is equipped with woven screen cloth, has improved the whole powerful and elongation at break index through broadwise of filtrate.
3, the lower floor of filtrate is the coarse denier fiber layer, the integral body of filtrate is played the reinforcement supporting role, and the filtration resistance of coarse denier fiber layer is low, helps improving the overall air permeability ability of filtrate.

Fig. 1 is the utility model structural representation.
The specific embodiment
The filtrate that is used for the ultrafine dust filtration as shown in Figure 1; Form by three-decker; Comprise the superfine Denier fibre layer 1 (0.05～0.08 dawn) on upper strata, the woven net layer of cloth 2 in middle level and the coarse denier fiber layer 3 (2.65 dawn) of lower floor, the content of superfine Denier fibre layer 1, woven net layer of cloth 2 and coarse denier fiber layer 3 is (weight portion): 185～220: 80～110: 185～220.The content of superfine Denier fibre, woven screen cloth and coarse denier fiber is preferably (weight portion): 200: 100: 200.The warp-wise of woven net layer of cloth 2 powerful for>=1600N (area is 50mm * 200mm), broadwise powerful for>=(area is that 50mm * 200mm), the mass area ratio of woven net layer of cloth 2 is 80～110g/m to 1500N
