Abstract
The utility model provides a glass fiber film coating filter material which has a good filtering effect, good temperature resisting performance, low production cost and long service life. The material comprises a filtering material; the upper surface and the lower surface of the filtering material are respectively provided with a polytetrafluoroethylene dipping treating layer; a polytetrafluoroethylene coating is coated on the outer surface of one of the polytetrafluoroethylene dipping treating layers; and a polytetrafluoroethylene film is coated on the polytetrafluoroethylene coating. The glass fiber film coating filter material has low filtering resistance, and good air permeability, and the air permeability amount can reach 8-15m<3>/m<2>.min. According to the glass fiber film coating filter material, accumulated dust can be filtered through the surfaces, a dust layer of the common filtering material does not need to be used for filtering, the pressure dropping is low, the electricity consumption of a fan is saved, dust cleaning times is reduced and the dust cleaning period is prolonged, and the investment and the running cost of devices can be effectively reduced; and as a film is coated on the coating, the structure is compact, and firm and durable, and the filtering accuracy of the filtering material can be effectively improved.
Description
Technical field
The utility model relates to a kind of filtering material, especially a kind of glass coated filter material.
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 glass coated filter material of long service life.
Realize the glass coated filter material of the utility model purpose; Comprise filtrate; Respectively be provided with polytetrafluoroethylene (PTFE) impregnation process layer on the upper and lower surface of this filtrate; The outer surface of a polytetrafluoroethylene (PTFE) impregnation process layer applies polytetrafluorethylecoatings coatings therein, on said polytetrafluorethylecoatings coatings, is covered with polytetrafluoroethylene film.
Said filtrate is for weaving filter cloth or non-woven filtrate.
Described non-woven filtrate is a filter felt.
The thickness of said polytetrafluorethylecoatings coatings is 20～200 μ m.
The beneficial effect of the utility model glass coated filter material is following:
1, the filtration resistance of the glass coated filter material 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.
6, overlay film again after the coating, structure is careful, and firm and durable has improved the filtering accuracy of filtering material effectively.
Description of drawings
Fig. 1 is the structural representation of the glass coated filter material of the utility model.
The specific embodiment
As shown in Figure 1; The glass coated filter material of the utility model; Comprise filtrate 3; Respectively be provided with polytetrafluoroethylene (PTFE) impregnation process layer 2 on the upper and lower surface of this filtrate 3, the outer surface of a polytetrafluoroethylene (PTFE) impregnation process layer 2 applies polytetrafluorethylecoatings coatings 1 therein, on said polytetrafluorethylecoatings coatings, is covered with polytetrafluoroethylene film 4.
Said filtrate 3 is for weaving filter cloth or non-woven filtrate, and said non-woven filtrate is a filter felt.
The thickness of said polytetrafluorethylecoatings coatings 1 is 20～200 μ m.
The glass coated filter material 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 glass coated filter material surface of the utility model almost can be held back the whole dust in the dust-contained airflow, has high filter efficiency.Overlay film again after the coating, structure is careful, and firm and durable has improved the filtering accuracy of filtering material effectively.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 also is superior to traditional filtrate.It has become " both surface filtration " with " in-depth filtration " of traditional filtrate.
