Abstract
The utility model discloses a fluoride glass high-temperature composite needled felt, wherein a base fabric layer (3) is used as a support; the upper surface and the lower surface of the base fabric layer (3) are covered by a mixed fiber layer (2); the mixed fiber layer (2) is a glass fiber and polysulfonamide fiber combined layer; a modified fluorocarbon resin coating (1) is externally coated on the mixed fiber layer (2) on one side for finishing; and the proportion of glass fibers to polysulfonamide fibers in the mixed fiber layer (2) is 1:1. The fluoride glass high-temperature composite needled felt is a needled felt with high cost performance, which has the advantages of high temperature fluctuation resistance, high filtration efficiency, high severe environment damage resistance, long service life, low operation resistance and high processing air volume, and is particularly suitable for being used in a dust removal working condition of kiln tail gas of a cement rotary kiln.
Description
Technical field
The utility model relates to industrial smoke dust removal by filtration technical field, is specifically related to a kind of fluorine Bo Gaowen compound spiked felt.
Background technology
Cement operating mode industry is still the key object of current domestic strict control dust discharge amount at present, during " 12 ", not only requires cement industry will dust discharge amount be controlled at 30mg/Nm especially now
3Below, but also advocate the advanced high temperature filtration product that will constantly develop efficient low energy.
The dedusting of existing cement kiln end operating mode can not adapt to well with filter bag that kiln end temperature fluctuation is big, dust-filtering efficient is undesirable, rely on external imported product but not production domesticization, and manufacturing cost is crossed problems such as height.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides that the fluctuation of a kind of heatproof is big, filtration efficiency, high adverse environment resistant destruction, long life, low running resistance, handles the high performance-price ratio compound spiked felt of air quantity greatly.
For achieving the above object; The technological means that the utility model adopted is; A kind of fluorine Bo Gaowen compound spiked felt is a support with the base cloth layer, covers with mixed fiber layer in the top and bottom of base cloth layer; It is characterized in that: said mixed fiber layer is glass fibre and polysulphonamide fiber combination layer, is coated with modification fluorocarbon resin coating outside on the mixed fiber layer of a side to put in order.
Preferably, said base cloth layer adopts the PTFE base cloth.
The beneficial effect of the utility model is: the fluorocarbon modified resin that is used for top finish is on the basis of conventional polyflon, strand to be carried out modification; Make it have excellent performance such as bonding, crosslinked, stiffening; Can effectively resist big air quantity dedusting environment, adaptability is good, and the complex environment of anti-operating mode infringement is strong; Life-span is longer, and efficiency of dust collection is higher; Mixed fiber layer adopts the high temperature fiber raw material of homemade universalness; Fiber is moderate, has acid and alkali-resistance, resistance to oxidation hydrolysis and excellent properties such as high temperature resistant, and the heatproof fluctuation is big; Can dust emission concentration be controlled at below the 30mg, can be applicable in the middle of the rotary cement kiln kiln exit gas dedusting operating mode.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, fluorocarbon modified resinous coat, 2, mixed fiber layer, 3, base cloth layer.
The specific embodiment
As shown in Figure 1; A kind of fluorine Bo Gaowen compound spiked felt middle is used for the load-bearing carrier of dust-filtering with base cloth layer 3 as Nomex, and base cloth layer 3 adopts the PTFE base cloths; Cover with mixed fiber layer 2 in the top and bottom of base cloth layer 3; Mixed fiber layer 2 is glass fibre and polysulphonamide fiber combination layer, and glass fibre and polysulphonamide fiber combination layer adopt glass fibre and two kinds of fibers of fragrant sulfone synthetic fibre to form by 1: 1 mixed, through needing machine with base cloth layer 3 with after two mixed fiber layer 2 acupunctures become felt; It is carried out the typing of tetrafluoro emulsion heat of immersion, to reinforce the interfibrous obvolvent of felt body and to improve anti-extraneous infringement ability; Secondly fluorocarbon modified resinous coat 1 is coated in the felt surface behind the dipping and put in order, make its surface form the membranaceous coating of one deck dense thin to improve strainability, last press polish becomes the Nomex finished product, has the stereoscopic three-dimensional space structure of small-bore, many porositys.It is sewn into filter bag during concrete the use, and the dust interception that mainly cooperates deduster to be used for rotary cement kiln kiln tail operating mode is gathered dust.
