Description
Technical field
The invention belongs to a kind of special sewing thread for sewing filtering bag, particularly relate to a kind of composite sewing thread for sewing polyphenylene sulfide filter bag.
Background technology
Polluting administering industrial waste gas, alleviate in the field that atmospheric environment is endangered by haze, the control emission of coal-fired power plant is an importance.In recent years, undertaking the technical way of solid particulate matter emission control in coal-fired plant boiler waste gas is bag type dust removing technology and electricity, bag one composite dedusting technology, because both technology all refer to the use of dust removal and filtration bag, and adapt to filtrate first-selection polyphenylene sulfide (PPS) filtrate of coal-burning power plant's exhaust filtering operating mode or the filtrate being composited with polyphenylene sulfide fibre with other high-performance fiber, such as polyphenylene sulfide fibre mixes compound spiked felt, the spun lacing felt that (PPS+PTFE) makes with polytetrafluoroethylene fibre.Because media performance adapts to coal-burning power plant's exhaust temperature and has the operating mode of certain acid corrosion, newly go up the transformation project that engineering is still carried out for emission compliance, be substantially all and select this kind of filtrate a large amount of.
Example: in a domestic large-scale Thermal generation unit of relatively advanced 1000MW, the filter bag of the filtrate 160 × 8000 of needs 2000, filtrate area is just up to more than 80000 square metres.If PPS Yu PTFE is according to the proportioning of 60:40, then need PPS fiber 30 tons, PTFE chopped fiber 20 tons, PTFE base fabric 11 tons.
For improving the service life of filter bag, filtrate enterprise makes polyphenylene sulfide and the filter bag of composite filtering material thereof at present, almost all selects the politef sewing thread sewing with superior chemical performances such as heatproof, corrosion-resistant, antioxidation and hydrolysis, High-Speed Automatic sewing machine for sewing filtering bag bag body typically selects line density specification to be 1350dtex(1200den), fracture strength reaches more than 3.5cN/dtex, use three strands of monofilament pool capital and be twisted into, then need to select the line of more high linear density specification to use according to design at the bottom of bag mouth, bag.But, while politef sewing thread meets the resistance to gentle chemistry of filter bag and mechanics function needs, also occur in that a variation rather perplexing filter bag manufacturing enterprise, it is simply that the leakage ash problem of filter bag sewing pin hole.Specifically: because manufacturing the needs that polyphenylene sulfide fibre is adaptation filtration efficiency that filtrate uses, typically all select the fine fibre between line density 1.5-3dtex, these fabric hand are more fine and soft, and the initial modulus of fiber is relatively low, there is the material characteristics that the restoration after deformation is poor.After filtrate then shows as suture needle thorn needle outlet during sewing, the less resilience of fiber of pinhole edges resets, and sewing thread, through afterwards, still suffers from pinhole aperture around suture；Plus politef sewing thread smooth surface, the self-lubricity that material is had can cause obvolvent fastness between suture and filtrate relatively low, thus the dust granules causing sewing thread can not solidify pin hole obstruction well becomes pin hole occluder.So, filter bag is when cleaner unit works, and owing to discharging the effect of air inducing pressure, dust remains able to be penetrated by pin hole clearance, enters discharge, thus affects filter efficiency.For overcoming this shortcoming, current filter bag manufacturing enterprise major part is the way using silica gel manually to smear closure pin hole, filter bag is sewed needle tracking reworking, although also can obtain preferable effect, but result in substantial amounts of artificial waste.And if filtrate enterprise is to block pin hole to exchange as thicker sewing thread, in addition to needs increase material cost, foregoing politef profit certainly and not adhesiveness, it is also difficult to obstruction dust completely is escaped after penetrating pin hole, the most also can affect filter efficiency.
Therefore, tightened up coal-burning power plant's dust emission standard is put into effect in the Chinese government, bag type dust removing technology is had under the background that more filtration efficiency requires by coal-burning power plant, as one of technical factor improving media filtration efficiency, the research and development of " self-closing from resistance " technology of filter bag pin hole will have important value.Therefore, the present invention from this angle, has invented and a kind of can meet mechanical property, the chemical property that filter bag uses, the most also can not affect the sewing thread of filter efficiency because sewing pin hole.
Summary of the invention
The present invention provides a kind of composite sewing thread for sewing polyphenylene sulfide filter bag, and the sewing pin hole of filter bag can effectively be filled by this line, thus the dust reduced in dust removal and filtration penetrates, and improves media filtration efficiency.
