Abstract
A high-temp filtering material in the form of cloth, needled felt, or the substrate cloth of needled felt for the refractory cloth-bag duster is prepared from teflon fibers and other refractory fibers chosen from glass fibers, polyimide fibers and poly-phenyl thioether fibers.
Description
Technical field
The invention belongs to the technical field of filter cloth material, promptly provide a kind of and be applicable to for the manufacture method of high-temperature flue gas purification with the filtering material of sack cleaner.
Background technology
Sack cleaner is one of reliable apparatus of high-temperature flue gas purification, and it has particle arresting efficiency height, is not subjected to the advantages such as influence of the ratio resistance of dust.Sack cleaner uses glass cloth to make filtrate usually, and glass cloth originally can be done under 260 ℃ of temperature for a long time, but the folding resistance of glass cloth is relatively poor, and is damaged very fast under more frequent blowback condition, thereby reduced its service life.The woven high-temperature filter material of the polytetrafluoroethylene fibre of employing is also arranged in recent years, but its cost wants high more than glass fiber material, has influence on applying of it.
Summary of the invention
Purpose of the present invention particularly improves its service life when the cleaning high-temp flue gas in order to prolong the service life of bag-type duster filtering bag.
The present invention proposes a kind of is the manufacture method of the high-temperature filter material of raw material with the composite fibre, and it includes the politef fiber, it is characterized in that with polytetrafluoroethylene fibre and other high-temperature fibre and sth. made by twisting or blending or makes high-temperature filter material or base cloth.
Said other high-temperature fibre can be a glass fibre among the present invention, also can be polyimide fiber or polyphenylene sulfide fibre.
Said polytetrafluoroethylene fibre and other high-temperature fibre can be that long fibre also can be a short fiber among the present invention, can adopt cabling method to make covering yarn or wrap yarn with long fibre, but with short fiber then blending become yarn.
Said high-temperature filter material can be a filter cloth among the present invention, also can be Nomex or Nomex base cloth.
The polytetrafluoroethylene (PTFE) molecular structure is:
Have good decay resistance, except that motlten metal sodium and liquid fluorine, other all chemicals of ability, even be to boil also in the chloroazotic acid and do not change.The operating temperature range of its fiber is-269～250 ℃.
Glass fibre contains Na with it
+, K
+Ionic weight is divided into three kinds of high-alkali glass, medium-alkali glass fiber and alkali-free glass fibers, and the present invention mainly adopts medium-alkali glass fiber or alkali-free glass fiber, and its chemical corrosion resisting property is good, and its softening temperature is up to 550～750 ℃.
The molecular structure of polyimide is:
Its fiber has good radiation hardness, flame resistant performance and electrical property, and its operating temperature range is-310～+ 340 ℃.
The molecular structure of polyphenylene sulfide is:
In air, be heated to 450～500 ℃ and do not decompose, can long-term work under 280 ℃ of temperature.
The specific embodiment
To narrate the specific embodiment of composite fibre high-temperature-resistant filtering material of the present invention below, and the content of invention will be illustrated further and replenish in conjunction with these embodiment.
The present invention makes the technology of filter cloth and base cloth and divides two kinds:
A kind of be filament fiber and twist with the fingers or and close, promptly use covering yarn and wrap yarn technology, be heart yearn with the polytetrafluoroethylene (PTFE) long fibre, make covering yarn and wrap yarn with other high-temperature fibre coating polytetrafluoroethylene fibre, with this yarn weaving filter cloth or base cloth.
Another kind is a short staple spinning, and earlier with polytef flocks process cotton spinning operation: opening picking → comb and parallel cotton fibers prior to spinning → combing → slubbing is opened bar → two road drafting → slubbing → finespun and become the finespun line.
Perhaps adopt woolspinning process, polytef flocks is become fine yarn with scouring of wool → carding → combing → slubbing → finespun.
Again other high temperature resistant short fiber also is spun into fine yarn with identical method.
With above-mentioned polytetrafluoroethylene (PTFE) spun yarn and other high-temperature fibre spun yarn blending resultant yarn, be made into filter cloth or base cloth with this scribbled again.
Make the process using polytetrafluoroethylene fibre of Nomex and the short silk of other high-temperature fibre with method of the present invention and just make the high temperature resistant Nomex of composite fibre through cotton → all cotton → combings of shredding → mixings → feed → fold net → pre-needling → main acupuncture → have a shave → thermal finalization → singe → operations such as press polish.This high temperature resistant Nomex can directly be used as the sack cleaner filtrate, also can cooperate high temperature resistant base cloth to be used to make the compound highly dense surface layer fire resistant filter material of three gradients.
Embodiment 1
The polytetrafluoroethylene (PTFE) yarn of 80,160 of fixed heavy yarn count methods and 80,160 glass fiber yarn are made 40 or 80 complex yarns through the doubling operation.
Use common weaving process again, be made into 60～300 gram/m with shuttleless loom or air-jet loom
2Filter cloth or as the base cloth of Nomex.Its tensile strength should be: 1000N/5cm～7000N/5cm.
Embodiment 2
With 80 or 160 polytetrafluoroethylene fibre (F fiber) yarns and 80 or 160 polyphenylene sulfide fibres (PPS fiber) yarn through also, twist with the fingers the F-PPS composite yarn that technology forms 40 or 80.
With air-jet loom above-mentioned composite yarn is made composite acupuncture felt or Woven filter cloth.
Embodiment 3
Become 40 or 80 s' F-PI composite yarn with polyimide fiber (PI fiber) yarn blending with 80 or 160 polytetrafluoroethylene fibres (F fiber) yarn.
With shuttleless loom above-mentioned composite yarn is knitted and to be made composite acupuncture felt or Woven filter cloth.
Embodiment 4
Polytetrafluoroethylene (PTFE) weak point silk and the short silk of glass fibre are mixed the following operation of process:
Shredding → mixing → hello cotton → all cotton → combings → folded net → pre-needling → main acupuncture → have a shave → thermal finalization → singe → press polish → check → rolling
Just can be made into the Nomex of high temperature resistant filtration usefulness.
Embodiment 5
Polytef flocks and the short silk of polyphenylene sulfide fibre are mixed the following operation of process:
Shredding → mixing → hello cotton → all cotton → combings → folded net → pre-needling → main acupuncture → have a shave → thermal finalization → singe → press polish → check → rolling.Promptly can be made into the Nomex of high temperature resistant filtration usefulness.Above-mentioned Nomex can be directly used in the manufacturing sack cleaner, also can make the highly dense surface layer high-temperature-resistant filtering material of composite fibre three gradients with three kinds of different Nomex ligand cloth of fiber number.
Embodiment 6
Mix the following multiple working procedure of process with polytetrafluoroethylene fibre weak point silk and the short silk of polyimide fiber:
Shredding → hello cotton → all cotton → combings → folded net → acupuncture → have a shave → thermal finalization → singe → press polish → check → rolling.Make high temperature resistant filtration Nomex.
Other refractory fibrous material can also adopt as polybenzoxazole fibers (400～500 ℃ of heatproofs) or PBI fibre (500 ℃ of heatproofs), is convenient to work with them with the alkali-free glass fibre blending usually and more can gives full play to its heat resistance.
In addition, when making the composite fibre Nomex, visual raw-material situation is done suitable increase and decrease to above-mentioned operation, and the principle of its increase and decrease is will guarantee product on the one hand, will control production cost on the other hand, to obtain better economic benefit.
Make the composite fibre high temperature resistance filtration material with method of the present invention, make sack cleaner, it can enlarge the range of application of deduster, also can prolong the service life of deduster.
