Abstract
A high-temperature resistant composite needle punched felt filter material comprises glass fiber chopped strands, a fiber surface layer, warps and wefts, and is characterized in that the glass fiber chopped strands are mixed with a high-temperature resistant raw material to form the fiber surface layer and a bottom layer via a lapping machine, the warps and the wefts are woven to form base fabric, the fiber surface layer and the base fabric are punched and trimmed simultaneously by a needling machine and then are manufactured into the high-temperature composite needle punched felt filter material, and after emulsion osmotic treatment, fine-filter three-dimension micropore stereo structures are formed on a deep layer of the inside of the needle punched felt. The filter material is adaptable to product recovery and high-temperature smoke filtration in industries of carbon black, coal firing boilers and the like, is adaptable to bag filters for pulse dedusting and high-speed back blowing, has fine performance, can be used for effectively treating dust pollution and recovering valuable miniature grains, and prolongs service life by 20%-30% compared with the conventional product.
Description
Technical field
The utility model relates to the material that a kind of exhaust gas dust dust removal by filtration is used, particularly a kind of high temperature resistant compound spiked felt filtrate.
Background technology
For the material that the exhaust gas dust dust removal by filtration is used, general representative woven filtrate is to use conventional methods manufacturing, so there are drawbacks such as production procedure is long, speed of production is low.Also exist and contain in the severe corrosive gas operating mode.In addition, the filtrate of the highly difficult purified treatment use of dust such as bituminous coal fired boiler, silica flour smelting has: PPS, P84, NOMEX etc., these products involve great expense, for production brings very big cost pressure.
Summary of the invention
For solving the problem that prior art exists, the utility model proposes a kind of filter precision height, little, the resistant to elevated temperatures compound spiked felt filtrate of resistance.
The technical scheme that the utility model is taked is: a kind of high temperature resistant compound spiked felt filtrate, comprise: the short chopping of glass, fiber surface layer, warp thread, weft yarn, it is characterized in that: select for use short chopping of glass and high temperature resistant raw material to mix, form fibrous face layer and bottom by the lapping machine; Be made into base cloth by warp thread and weft machine; Fiber surface layer and base cloth are made a spurt and are had a shave by needing machine simultaneously, make high temperature resistant compound spiked felt filtrate; Nomex is through emulsion infiltration processing; The smart filter of inner deep layer three-dimensional micropore stereochemical structure.Described high temperature resistant raw material can be: carbon fiber or polytetrafluoroethylene fibre.
The utility model has the advantages that: this product is applicable to that the finished product of industries such as carbon black, coal-burning boiler reclaims, and high-temperature flue gas filters.Be applicable to pulse dust cleaning, use in the bag hose of high speed blowback that function admirable can effectively be administered dust pollution, reclaims valuable subparticle, improve 20-30% service life with product than former.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
High temperature resistant compound spiked felt filtrate comprises: the short chopping 1 of glass, fiber surface layer 2, warp thread 3, weft yarn 4, and select for use short chopping 1 of ultra-fine 80s glass and high temperature resistant material carbon fiber to mix, form fibrous face layer 2 and bottom by the lapping machine; Become base cloth with warp thread 3 and weft yarn 4 are woven, by four plate needing machines through 240 per minutes of two-forty, walk secondary speed 0.5m/min and 420 per minutes of speed of having a shave, walk the fiber carding machine of secondary speed, make high temperature resistant compound spiked felt filtrate by lapping machine formation fibrous face layer 2 and bottom.Nomex also will be handled through the emulsion infiltration; The smart filter of its inner deep layer three-dimensional micropore stereochemical structure.High temperature resistant raw material can adopt carbon fiber or polytetrafluoroethylene fibre.
Claims (2)
1. high temperature resistant compound spiked felt filtrate comprises: the short chopping of glass, fiber surface layer, warp thread, weft yarn is characterized in that: select for use short chopping of glass and high temperature resistant raw material to mix, form fibrous face layer and bottom by the lapping machine; Be made into base cloth by warp thread and weft machine; Fiber surface layer and base cloth are made a spurt and are had a shave by needing machine simultaneously, make high temperature resistant compound spiked felt filtrate; Nomex is through emulsion infiltration processing; The smart filter of inner deep layer three-dimensional micropore stereochemical structure.
