Abstract
The utility model relates to a glass-fiber-coated needled felt which is characterized in that two composite fiber layers are respectively and symmetrically stuck on the upper surface and the lower surface of glass fiber base cloth; each composite fiber layer is formed by compositing polyphenylene sulfide (PPS) and aramid fibers; a polytetrafluoroethylene microporous film is composited on the upper surface of the needled felt by a needle machine. The glass-fiber-coated needled felt has the characteristics of resisting corrosion and high temperature, being easy in dust cleaning, high in filtering accuracy and long in service life, etc.
Description
Technical field
The utility model relates to a kind of filter felt, particularly a kind of glass laminated needled felt.
Background technology
At present, the flue-gas temperature of the industries such as cement plant, steel plant, power plant, chemical plant is higher, containing the material composition complexity such as acid, alkaline, common Nomex be difficult to meet its high-temperature particle thing to the calcination of filter bag and corrosive gas the destruction to filtrate; And general acupuncture felt filtering accuracy is not high, easy dewfall, deashing work is loaded down with trivial details.
Summary of the invention
The utility model is in order to solve above-mentioned deficiency, provides a kind of corrosion-resistant, high temperature resistant, the glass laminated needled felt of easy-to-clean ash.
Above-mentioned purpose of the present utility model realizes by following technical scheme, and a kind of glass laminated needled felt, is characterized in that: be the symmetrical composite fibre layer of pasting of upper and lower surface at glass base cloth, composite fibre layer is to be composited by PPS and aramid fiber; At the upper surface of Nomex, with the compound one deck polytetrafluoroethylene (PTFE) of needing machine pore membrane.
Superior effect of the present utility model is as follows:
1, high temperature resistant, 180 ℃ of normal working temperatures, moment 220 ℃ of heatproofs;
2, antiacid caustic corrosion, anti-chemistry are very strong;
3, filtering accuracy is high, and dust removing effects reaches 99%;
4, adopt film surface to filter, the glass properties of dust is good, easy-to-clean ash;
5, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure explanation, 1-glass base cloth, 2-composite fibre layer, 3-microporous teflon membran.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in structural representation as of the present utility model in accompanying drawing, the utility model provides a kind of glass laminated needled felt, and it is to be the symmetrical composite fibre layer 2 of pasting of upper and lower surface at glass base cloth 1, and composite fibre layer 2 is to be composited by PPS and aramid fiber; At the upper surface of Nomex, with the compound one deck microporous teflon membran 3 of needing machine; Post processing mode has: high temperature hot pressing and singe, refuse water, anti-oil processing.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous serviceability temperature of the present utility model is 180 ℃, moment serviceability temperature be 220 ℃, warp-wise fracture strength >=2200N/520cm, broadwise fracture strength >=2200N/520cm, warp-wise elongation at break≤10%, broadwise elongation at break≤10%, rupture strength >=3.8MPa, thickness 1.8-2.2mm, Air permenbility 200-400L/ ㎡ * min.
