Description
Technical field
The utility model relates to the technical field of modified polyphenyl thioether filter bag sewing thread, specially a kind of modified polyphenyl thioether
The compound filter bag sewing thread of sewing thread.
Background technique
With the reinforcement of Environmental Protection in China dynamics, government further increases air contaminant treatment dynamics.Coal-burning power plant row
One of the main source as industrial gas emission is put, has obtained unprecedented attention, discharge standard is via original
30mg/Nm3It is increased to 20-10mg/Nm3, some areas 5mg/Nm3.Major technique as control dust particle is removed for pocket type
Dirt technology has become the major technique of coal-burning power plant's dust removal by filtration because having good dust emission control effect.According to system
Meter, by the end of the year in 2016, China's capacity of installed generator was up to 16.5 hundred million kilowatts, wherein 9.4 hundred million kilowatts of coal electricity installed capacity；Power generation
Amount is up to 6.0 trillion kilowatt hours, and wherein about 3.9 trillion kilowatt hour of coal fired power generation amount, accounts for the 65.5% of total power generation.And 9.4 hundred million
In kilowatt coal electricity, about 30% uses bag-type dusting or electric bag composite dedusting.According to data, a relatively advanced 1000MW is big
In type Thermal generation unit, the filter bag of the filtrate 160 × 8000 needed 2000, filtrate area is just more than 80,000 square metres reachable,
Thus it sees, China has had 5,000 ten thousand square metres of filtrate in the exhaust filtering task of carrying coal-burning boiler.And this part uses bag
The dedusting filtering bag of formula dedusting technology is essentially all using the polyphenyl thioether filter material or polyphenyl that can adapt to coal fire discharged operating condition
The production of the composite filtering material of thioether and polytetrafluoroethylene (PTFE), sulphur, nitrogen compound preferably to adapt in coal fired power generation, in flue gas emission
Equal corrosive substances.To reach stringenter discharge standard, in terms of filtrate, filter bag production technology, there is superfine fibre,
The technological innovations such as fibrous material is compound, needle thorn is impregnated with Spunlace line compound use, overlay film, lotion, the closure of filter bag pin hole.?
In the use of filter bag sewing thread, general choice has the polytetrafluoroethylene (PTFE) sewing thread of good temperature tolerance and chemical-resistance, to increase
The heatproof of strong filter bag, corrosion resistance.But since polytetrafluoroethylene material is without the spy for having liquid fluidity under molten condition
Point only produces staple fiber by film strips cracking technology at present, the list made by pressing aid extrusion process or film strips separating and cutting process
Filament length is fine.And since polytetrafluoroethylene material has very strong self-lubricity, staple fiber can not spin, therefore, can only use in the industry
Monofilament plying production sewing thread.Thus polytetrafluoroethylene (PTFE) sewing thread just necessarily has surface smooth, and frictional force is small, the obvolvent with filtrate
Gu the disadvantage of attached power difference；Simultaneously because material property also have the shortcomings that wear no resistance lost with thermal creep it is strong.Exactly these defect institutes
It causes, the pin hole of filter bag cannot deposit dust well in use, and form dust particles to block pin hole, prevent dust
It is penetrated by pin hole, to affect filter efficiency.Currently, emission request is in 15mg/Nm3Within project in, filter bag pin hole need
It wants silica gel coating closure or adhesive tape hot melt to block, so that the manufacturing to filter bag brings no small manpower and material resources waste, increases
Production cost is added.
Utility model content
The purpose of this utility model is to provide a kind of modified polyphenyl thioether filter bag sewing threads, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of modified polyphenyl thioether filter bag sewing thread,
It is made of modified polyphenyl thioether filter bag sewing thread, modified polyphenyl thioether yarn and nylon material yarn, the modified polyphenyl sulphur
Ether filter bag sewing thread, which is wrapped in, forms cored by the outer surface that modified polyphenyl thioether yarn and nylon material yarn alternate lay of stranding synthesize
Knot structure, and core yarn structure is individually to be twisted together it in the direction of the clock respectively by modified polyphenyl thioether yarn and nylon material yarn
After remerge and be twisted together into stock counterclockwise, the modified polyphenyl thioether filter bag sewing thread outer surface is coated with colloid wax.
Preferably, the nylon material yarn is the nylon material yarn merged for the multiply of sub-thread or two strands or more.
Preferably, the modified polyphenyl thioether filter bag sewing thread is the modified polyphenyl of the multiply merging of sub-thread or two strands or more
Thioether filter bag sewing thread.
Preferably, the modified polyphenyl thioether yarn is the modified polyphenyl thioether yarn of the multiply merging of sub-thread or two strands or more
Line, and modified polyphenyl thioether yarn is flat yarn.
Compared with prior art, the utility model has the beneficial effects that the filter bag seam that modified polyphenyl thioether sewing thread is compound
Line high temperature resistant, the corrosion-resistant and oxidation resistance of threading are strong, meet the principle that sewing thread performance is better than media performance, modified polyphenyl thioether
Nylon material tenacity of yarn in the compound filter bag sewing thread of sewing thread is good and wear-resisting, then combines with modified polyphenyl thioether yarn
Make to enhance the intensity of the compound filter bag sewing thread of modified polyphenyl thioether sewing thread, to improve service life, be filtered improving
While bag service life, additionally it is possible to realize that blocking up certainly for pin hole is self-closing by the feather of its outer surface, be unlikely to influence because of pin hole
Integral filter efficiency is reduced and is blocked or cost wastes caused by other technological means block pin hole because artificial, has centainly
Economic value and the meaning for promoting environmental protection.
