Abstract
The utility model provides a filtrating felt which can be resistant to high temperature smoke for coal burning boiler of thermoelectrical plant. The filtrating felt is made from outside to inside by: 1, 2.2dtex is multiplied by 51mm PPS fiber layer; 2, 2.2dtex multiplied by 51mm PPS filament base cloth; 3, 2.2dtex multiplied by 51mm PPS fiber layer. The utility model has the advantages of high mechanical intensity, good stability; smooth surface, dust proof and good dust cleaning effect; high filtrating precision, high corrosion resistance; and high oxidation resistance capability.
Description
Technical field
The utility model relates to a kind of dust removal and filtration felt that is used for the circulating fluid bed garbage furnace high-temperature flue gas.
Background technology
At present, be exclusively used in the filter cloth or the felt of the dedusting of circulating fluid bed garbage furnace high-temperature flue gas on the market, effect is all undesirable, does not still have a kind of more effective filtrate.
Summary of the invention
For solving foregoing problems, the utility model provides a kind of dust removal and filtration felt that is exclusively used in the circulating fluid bed garbage furnace high-temperature flue gas, this filter felt structure from the surface to nexine is successively: specification is 2.2dtex * 51mm polyphenylene thioether PPS fibrage, specification is 2.2dtex * 51mm polyphenylene thioether PPS base cloth, and specification is 2.2dtex * 51mm polyphenylene thioether PPS fibrage.
The utility model has the advantages that:
1, the mechanical strength height, dimensional stability is good.
2, smooth surface, because after the impregnation process of filter felt via the PTFE dispersion emulsion, felt material smooth surface is difficult for being stained with ash, ash-removal effect is good.
3, the filtering accuracy height, the specification that the production technology of traditional polyphenylene sulfide is produced is every square metre 500 gram, and current technology is every square metre 550 gram of specification, has increased fibrolaminar weight, but has adjusted on needling process, thickness keeps original back degree, thereby has improved filtering accuracy.
4, improve decay resistance, polyphenylene sulfide fibre itself has good decay resistance and anti-hydrolysis ability, again after special P TFE oozes the film processing, because PTFE has anti-any chemical attack ability, makes the corrosion resistance of this felt material be further improved.
5, improve oxidation resistance, the maximum shortcoming of polyphenylene sulfide fibre itself is exactly that oxidation resistance is poor, owing to be the impregnation process that in last handling process, has adopted the PTFE emulsion, and through hot setting, make the fiber surface adhere to the well-proportioned PTFE material of one deck, reduced fiber and directly contacted, thereby improved the non-oxidizability of this felt material with oxidizing gas in the flue gas.
Description of drawings
Accompanying drawing is cross section structure figure of the present utility model.
The specific embodiment
See also shown in the accompanying drawing, the utility model structure from the surface to nexine is successively: specification is 2.2dtex * 51mm polyphenylene thioether PPS fibrage 1, specification is 2.2dtex * 51mm polyphenylene thioether PPS base cloth 2, specification is 2.2dtex * 51mm polyphenylene thioether PPS fibrage 3, and 4 among the figure is flow directions of air-flow to be filtered.
The utility model is used for the dedusting of circulating fluid bed garbage furnace high-temperature flue gas long bag and low pulse.
Result of use is:
1, be 2 years under normal operation service life.
2, normal serviceability temperature 120--150 ℃, 170 ℃ of instantaneous temperatures.
3, filtration velocity be 1.1-1.2 rice/minute
4, the concentration of emission design load is below 50 milligrams/cubic metre, and actual discharge concentration is lower than 30 milligrams/cubic metre.
5, dust remover resistance is less, and design load is 1500 handkerchiefs, and actual is about 1350 handkerchiefs.
Claims (1)
1, the corrosion-resistant permeable filter felt of a kind of polyphenylene thioether PPS is characterized in that: this filter felt structure from the surface to nexine is successively: polyphenylene thioether PPS fibrage, polyphenylene thioether PPS base cloth, polyphenylene thioether PPS fibrage.
