Abstract
The utility model provides a tectorial membrane filter bag. It includes tectorial membrane and base cloth layer, the tectorial membrane is located the base cloth layer outside, the tectorial membrane adopts the polytetrafluoroethylene microporous membrane, and this polytetrafluoroethylene microporous membrane is equipped with 0.1 -3.5 mu m's micropore aperture, and the micropore porosity reaches 75 -90%, the fine bulk yarn fibre in succession of alkali -free glass is adopted on the base cloth layer, the unit area quality is 46 -122.7gm2, thickness is 0.64 -1.39mm, fibre web the average pore size is 11.385 mu m -24.9691 mu m, tectorial membrane filter bag has realized surface filtration, dust emission amount almost is zero, improve the throughput of dust -collecting equipment, reduce the differential pressure of dust -collecting equipment, the life of filter bag has been prolonged, deashing cycle and power consumption have been reduced, save the maintenance expense of dust -collecting equipment, improve the filtration velocity of dust -collecting equipment, with use volume and the investment that reduces the dust -collecting equipment cost is reduced.
Description
Technical field
This utility model relates to the membrane bag filter of sack cleaner especially sack cleaner filter bag.
Background technology
The Workplace powder ash of the industries such as current building materials, chemical industry, metallurgy and mining is big, and containing moisture in dust, need dust arrester to remove powder ash, can the sock filtration weak effect of existing cleaner unit, efficiency of dust collection is low, in dust removal process, powder ash there will be the phenomenon forming dust through filter bag, damages the healthy of labourer, and dedusting filtering bag need to frequently be changed, delay production, increase labour force, increase production cost, reduce labor efficiency.
Thin film is laminating at basis filter material surface, coated filter material is to use the three-dimensional reticular fiber of its film surface and its small micropore to filter, thus eliminating the necessity forming primary filter dirt cake, the granule of film surface cannot be introduced between the fiber of filter bag and fiber, therefore use pressure reduction and the air penetrability of membrane bag filter will not be affected in prolongation over time.Owing to filter effect results from film surface, thus less dust leakage can be produced, less Pressure Drop, and higher air quantity.It is a kind of special filtering technique, can create optimal treatment effect for any filtrate, thus higher filter efficiency can be provided > 99.99%, excellent ash-removal effect, and exhaust air rate higher in the level of low energy consumption.Thin film can really avoid dust to harden when using, and remains to keep the efficiency of dust collection of more than 99.999% simultaneously.Prolongation over time, the granule on filter bag surface cannot be introduced into the surface of this thin film therefore the use pressure reduction of its membrane bag flter and air penetrability will not be affected.After using a period of time, under identical working condition, the filtration pressure difference of BHA membrane bag flter is lower by 20%～40% than common glass in-depth filtration product, it is thus possible to increase the process ventilation flow rate of system, is greatly saved the power consumption of cleaner blower fan simultaneously.
Summary of the invention
In order to solve the deficiency of existing sock filtration effect, this utility model provides a kind of membrane bag filter, adopts overlay film microporous teflon membran, this membrane bag filter energy thoroughly Chalk-dust filtering, extends the physical life of filter bag greatly, improves production efficiency.
This utility model solves its technical problem and be the technical scheme is that a kind of membrane bag filter, it includes overlay film and base cloth layer, described overlay film is positioned at outside base cloth layer, described overlay film adopts microporous teflon membran, this microporous teflon membran is provided with the micropore size of 0.1-3.5 μm, micropore rate reaches 75-90%, and described base cloth layer adopts the continuous buiky yarn fiber of alkali-free glass fiber, and mass area ratio is 46-122.7g/m2, thickness is 0.64-1.39mm, and fibre web average pore size is 11.385 μm-24.9691 μm.
This membrane bag filter energy thoroughly Chalk-dust filtering, extends the physical life of filter bag greatly, improves production efficiency.
The beneficial effects of the utility model are: this utility model achieves surface filtration, dust discharge amount is almost nil, improve the ventilation of dust-collecting equipment, reduce the Pressure Drop of dust-collecting equipment, extend the service life of filter bag, decrease cleaning cycle and power consumption, save the maintenance expense of dust-collecting equipment, improve the filtration velocity of dust-collecting equipment, reduce and reduce use volume and the cost of investment of dust-collecting equipment.
