Abstract
The utility model discloses a filter material with the surface adopting composite superfine short fibers, comprising a surface layer, a base fabric and a bottom layer, wherein the bottom layer is formed by needling glass fibers, polyphenylene sulfide fibers and polytetrafluoroethylene fibers; the surface layer is formed by needling polyphenylene sulfide short fibers and polytetrafluoroethylene short fibers; the filter material is characterized in that the end surface of the surface layer is also melt-sprayed or hot-pressed with a composite layer formed by glass superfine short fibers, polyphenylene sulfide superfine short fibers and polytetrafluoroethylene superfine short fibers; the fineness of the glass superfine short fibers in the composite layer is 0.3-1.0dtex, the fineness of the polyphenylene sulfide superfine short fibers is 0.4-1.5dtex; and the fineness of the polytetrafluoroethylene superfine short fibers is 0.6-1.2dtex; and the mass ratio of the glass superfine short fibers, polyphenylene sulfide superfine short fibers and polytetrafluoroethylene superfine short fibers in the composite layer is 1:1:1.5-1:1:0.5. The filter material has the advantages of aiming at smoke and dust with different properties for filtering, lowering filtration resistance, reducing energy consumption, prolonging the service life of the filter material and the like, and is applicable for raping, blowback and other filter-bags.
Description
Technical field:
The utility model relates to a kind of bag-type dusting filtrate, particularly relates to the filtrate of a kind of surface with composite superfine staple.
Background technology:
The bag-type dusting filtrate is to enter the Nomex filtrate from early stage flannelette filtrate, woven cloth filtrate, and then develops into coated filter material, and coated filter material is to be substrate with woven filtrate or Nomex filtrate, covers one deck polytetrafluoroethylmicroporous microporous membrane in its surface.The filtrate overlay film forms later on based on surface filtration, the existence of polytetrafluoroethylmicroporous microporous membrane can stop that really the fine particle in the middle of the dust passes through, thereby can improve filter efficiency greatly, polytetrafluoroethylmicroporous microporous membrane can play the effect of dust bonding layer on the surface of Nomex, and have certain hydrophobic, oleophobic ability, smooth surface event owing to polytetrafluoroethylmicroporous microporous membrane makes deashing become easily again, and has high efficiency of filtration.But also there is certain problem behind the overlay film, it mainly is that the dust removal and filtration initial resistance is big, and the dust removal and filtration wind speed can not be too high, and, also there is problems such as being difficult to the precoating ash, therefore, produce use cost and improve, in addition, film micropore is easily impaired, or cause that film comes off, cause that filtrate can't use, and influences result of use.
Summary of the invention:
The purpose of this utility model is that the filtrate of a kind of surface with composite superfine staple will be provided, and it not only can be effectively used to filter at flue gas of different nature, dust, and, can also reduce filtration resistance, reduce energy consumption, prolong the service life of filtrate.
Solution of the present utility model to achieve the above object is: surface of the present utility model comprises a surface layer, base cloth and bottom with the filtrate of composite superfine staple, described bottom is made of glass fibre, polyphenylene sulfide fibre and polytetrafluoroethylene fibre acupuncture, described surface layer is formed by polyphony thioether short fiber and polytef flocks acupuncture, also melts and sprays on the end face of described surface layer or hot pressing has by glass micro staple fiber, polyphenylene sulfide micro staple fiber and the formed composite bed of polytetrafluoroethylene (PTFE) micro staple fiber.
The fineness of the glass micro staple fiber in the described composite bed is 0.3-1.0dtex, and the fineness of polyphenylene sulfide micro staple fiber is 0.4-1.5dtex, and the fineness of polytetrafluoroethylene (PTFE) micro staple fiber is 0.6-1.2dtex.
Mass ratio between glass micro staple fiber in the described composite bed, polyphenylene sulfide micro staple fiber and the polytetrafluoroethylene (PTFE) micro staple fiber is 1: 1: 1.5-1: 1: 0.5.
Because the utility model has adopted and has melted and sprayed on the end face of the surface layer of being made up of polyphony thioether short fiber and polytef flocks acupuncture or hot pressing has by the glass micro staple fiber, polyphenylene sulfide micro staple fiber and the formed composite bed of polytetrafluoroethylene (PTFE) micro staple fiber, it had both kept the characteristic of the Nomex filtrate of gradient-structure, the function that has the surface coating filtrate again, initial resistance than coated filter material is low, the initial resistance that has overcome the surface coating filtrate is big, film comes off easily, problems such as obstruction, also reduced the resistance of filtrate integral body, compare with the surface coating filtrate, the filtrate composite bed is to dust catching efficient in the filter process, the deashing ability has all obtained improving largely, and be difficult for stopping up the small pore of filtrate composite bed, good permeability, thereby reduce the pressure drop of filtrate, reduce the deashing number of times, energy savings, the while can also prolong the service life of filtrate.
Simultaneously, because the existence of polytetrafluoroethylene (PTFE) micro staple fiber, and the polytetrafluoroethylene (PTFE) micro staple fiber has anti-height, low temperature, favorable mechanical toughness, excellent mechanical property, ability chloroazotic acid and all organic solvents, anti-flammability, weatherability, chemical stability, self lubricity, electrical insulating property, wear resistance and anti-aging endurance reach light and ozonization etc. all are better than other fibers, so also improved the glass micro staple fiber, the non-oxidizability of polyphenylene sulfide micro staple fiber, hydrolytic resistance, resistance to corrosion to soda acid gas, delay its performance aging, enlarged the glass micro staple fiber, the environment for use of polyphenylene sulfide micro staple fiber filtrate and prolonged service life.
In a word, the filtrate that composite superfine staple is used on a kind of surface of the present utility model has also improved the complete machine performance of sack cleaner, and can be widely used in multiple bag dust collectors such as blowback wind, mechanical vibrator, pulse backblowing when reducing use cost.
