Abstract
The utility model provides high-precision coated machine-woven filter cloth which is good in filtering effect, excellent in temperature resistance property, low in production cost and long in service life. The high-precision coated machine-woven filter cloth comprises machine-woven filter cloth, wherein the upper surface and lower surface of the machine-woven filter cloth are respectively provided with a polytetrafluoroethylene immersion treatment layer, and the outer surface of one polytetrafluoroethylene immersion treatment layer is coated with a polytetrafluoroethylene coating. The high-precision coated machine-woven filter cloth is low in filtering resistance and good in air permeability, and the air permeation volume reaches 8-15m<3>/m<2> min. A coating filter material filters dust through the surface, the dust layer of a common filter material is not needed in filtering, pressure drop is low, the fan power consumption is saved, the frequency of ash removal is reduced, the dust removal period is prolonged, and the investment and operation expenditure of equipment are effectively decreased; and as the surface of the polytetrafluoroethylene coating is smooth and has hydrophobicity, even humid dust is bonded, under the action of ash-removal external force, the bonded dust is easy to drop off and the balance of the filtering resistance is maintained.
Description
Technical field
The utility model relates to a kind of filtering material, especially a kind of high accuracy coating woven filter cloth.
Background technology
At present, in the heatproof dust removal by filtration cloth bag that the sack cleaner of industries such as cement, power plant, iron and steel, carbon black uses, the overwhelming majority all is to weave or non-woven processing with single material, in use exposes the defective of self:
The one, the defective of homogenous material various degrees, poor like the temperature tolerance and the non-oxidizability of PPS filtrate; The water-fast guards escorting prisoners of P84 fiber, price are higher; Low, the expensive of the tensile strength of PTFE fiber; The folding resistance of glass fibre and wearability are slightly poor.
The 2nd, the filtering material that adopts homogenous material to process, even the bisque that forms filters, the rate of filtration can not be excessive, otherwise pass through filter easily, so its filter effect is not ideal enough.
The 3rd, the exhaust gas dust that different airborne dust points produce; Its temperature, humidity, dust content, the chemical composition in the dust, particle diameter distribute, and the composition and the content of the pernicious gas in the flue gas all are not quite similar; Rely on the filtering material of single component, be difficult to accomplish effective filtration flue dust.
Simultaneously; At the dirt pits that removes that some dust contents are high, dust size is little, the corrosivity composition is many, humidity of flue gas is big, temperature fluctuation is big; Performance to filter material proposes higher requirement; Filtrate service life and dust emission concentration become a big difficult point of each operating mode smoke abatement and dust control, and common filtering material can not satisfy the filtration requirement of similar operating mode.
The utility model content
The utility model provides a kind of good filtration effect, heat resistance is good, production cost is low, the high accuracy coating woven filter cloth of long service life.
Realize the high accuracy coating woven filter cloth of the utility model purpose; Comprise woven filter cloth; Respectively be provided with polytetrafluoroethylene (PTFE) impregnation process layer on the upper and lower surface of this woven filter cloth, the outer surface of a polytetrafluoroethylene (PTFE) impregnation process layer applies polytetrafluorethylecoatings coatings therein.
The thickness of said polytetrafluorethylecoatings coatings is 20～200 μ m.
The beneficial effect of the utility model high accuracy coating woven filter cloth is following:
1, the filtration resistance of the high accuracy coating woven filter cloth of the utility model is low, good permeability, and Air permenbility reaches 8-15m
3/ m
2Min.The coating filtrate is through the surface filtration laying dust, and the dust layer that need not ordinary filter participates in filtering, and pressure drop is low, saves the blower fan power consumption, reduces the deashing number of times and prolongs cleaning cycle, has effectively reduced investment of devices and operating cost;
2, because polytetrafluorethylecoatings coatings almost can be held back the whole dust in the dust-contained airflow, filter efficiency is high, smooth surface and be easy to deashing; Coefficient of friction is low, and the fissility during deashing is good;
3, because the chemical resistance of polytetrafluoroethylene (PTFE) is good, high temperature resistant, heatproof is up to 260 ℃ continuously, and moment can reach more than 280 ℃;
4, polytetrafluorethylecoatings coatings is sticking more many more unlike the such generation of ordinary filter filter material surface dust, the phenomenon that cause and stick with paste bag, hardens, pressure reduction rises rapidly;
5, because the smooth surface of polytetrafluorethylecoatings coatings has hydrophobicity,, under the effect of deashing external force, also come off easily, keep filtration resistance steady even moist dust bonding is arranged.
Description of drawings
Fig. 1 is the structural representation of the high accuracy coating woven filter cloth of the utility model.
The specific embodiment
As shown in Figure 1; The high accuracy coating woven filter cloth of the utility model; Comprise woven filter cloth 3, respectively be provided with polytetrafluoroethylene (PTFE) impregnation process layer 2 on the upper and lower surface of this woven filter cloth 3, the outer surface of a polytetrafluoroethylene (PTFE) impregnation process layer 2 applies polytetrafluorethylecoatings coatings 1 therein.
The thickness of said polytetrafluorethylecoatings coatings 1 is 20～200 μ m.
The high accuracy coating woven filter cloth of the utility model is compared with common filter cloth: under identical dust containing capacity, Air permenbility is good, and filtration resistance is little.Its filtration velocity can improve 1/3, and SR reduces by 1/4, but the above granule dust of collection cut size 0.5 μ m, and dust removing rate is more than 99.99%.
The polytetrafluorethylecoatings coatings on the high accuracy coating woven filter cloth surface of the utility model almost can be held back the whole dust in the dust-contained airflow, has high filter efficiency.In addition because PTFE has self-cleaning and hydrophobicity; The coating filtrate is easy to deashing; Dust can not go deep into filtrate inside simultaneously; Also can be blown gradually even there are some fine dusts to get into filtrate inside, thereby can under the situation that does not increase running resistance, guarantee the maximum that air communication is crossed, collected dust cake is superior to traditional filtrate.It has become " both surface filtration " with " in-depth filtration " of traditional filtrate.
